PETRA 2021: The 14th PErvasive Technologies Related to Assistive Environments Conference

 

Part of the PROMISS diet trial was the persuasive technology sub study. For this sub study we designed a tablet application and foodbox that 48 participants could using during their diet trial for diet tracking. We studied the adherence (commitment to using the technology), protein intake, experience of dietary advice and technology, and the effect of gamification in our app on the protein knowledge of users. This paper presents the most important results.

Participants are positive about the tablet application, but negative about the foodbox. On average, participants used the tablet actively for 133 days. Participants stay committed during their use, 83% of the days that they used the tablet for were active days. We did not find a significant change in the protein intake of our participants, compared to participants without a tablet.

Based on these results we conclude that a diet tracking application designed for older adults is a feasible and appreciated tool to use within a dietary intervention study in older persons.

The PROMISS (PRevention Of Malnutrition In Senior Subjects) project presented its results in a hybrid conference on 25 June 2021. With the European population growing older, the challenge is to age healthily and actively. However, in Europe, between 20-50% of all older adults living at home are malnourished or at risk of protein energy malnutrition.

Based on the outcomes of the European-funded research project PROMISS (PRevention Of Malnutrition In Senior Subjects), it was concluded that for optimal physical functioning, older adults should eat at least 1.0 gram protein/kg bodyweight/day. However, more than half of the older adults does not meet this requirement. Based on these and other results PROMISS developed optimized, sustainable and evidence-based dietary and physical activity recommendations to prevent malnutrition and support active and healthy ageing.

 

Recommendations

Based on scientific evidence, PROMISS recommends the following for older adults on:

Protein intake

  • Consume more than 1.0 g protein per kg body weight per day as it benefits physical function;
  • Consume at least 30 g of protein in one meal per day and, if possible, in two meals per day;
  • Use protein-enriched food products to increase protein intake when appetite is poor or with a vegetarian diet;
  • Increase protein intake gradually and use products with a high protein density, and especially high protein drinks, to avoid feelings of fullness and bloating.
  • Older adults, their dietitians or health professionals should evaluate the protein intake with the Protein Screener at proteinscreener.nl.

 

A more sustainable diet

  • Eat more plant-based protein such as legumes, cereals, nuts and seeds;
  • It is not necessary to go completely vegan or vegetarian;
  • Eat less animal based protein (such as beef, lamb, and processed meats) and choose chicken and pork – if meat is eaten;
  • Fish should not be eaten more than once a week;
  • If fish is eaten, eco-labels on certified fish products such as the blue Marine Stewardship Council (MSC) logo, and Aquaculture Stewardship Council (ASC) logo should be considered.

 

Physical activity

  • Be physically active for at least 30 minutes per day, as it benefits physical function and quality of life, and helps to prevent frailty and protein-energy malnutrition;
  • The longer, the more frequent, and/or the more intensive older adults are physically active, the more their health will benefit;
  • Engage in activities that strengthen the muscles and bones, for example resistance training;
  • Sedentary behaviour should be reduced as much as possible, as this lowers the risk of functional decline and frailty.

Dietary protein may slow the decline in muscle mass and function with aging, making it a sensible candidate to slow down or even prevent disability progression. At present, studies providing reliable estimates of the association between protein intake and physical function, and its interaction with physical activity, in community-dwelling older adults are lacking. We wanted to investigate the longitudinal relationship between protein intake and physical function, as well as how the results varied with different physical activity levels. For this we used individual participant data from four cohorts in the PROMISS consortium (Health ABC, NuAge, LASA and Newcastle 85+) with more than 5700 participants living in the community and followed up to almost 9 years. We found that higher daily protein intake may reduce physical function decline not only in older adults with protein intake below the current recommended dietary allowance of 0.8 grams/kg bodyweight/day, but also in those with a protein intake that is already considered sufficient, i.e. above and beyond the 0.8 grams/kg bodyweight/day. This dose-dependent association was observed for all levels of physical activity, suggesting that the results on the association between protein intake and physical function do not change by physical activity level.

Eating adequate amounts of protein is important for the maintenance of health, independence, and quality of life especially for older adults. While meat is an important source of protein, it holds the most weight in the environmental impact of EU diets. This study aimed to gain a deeper understanding of meat consumption behavior among older adults by identifying and comparing different groups of older adults with differing patterns of meat consumption and liking.

A survey was conducted among 2,500 community-dwelling older adults aged 65+ years in Finland, Poland, Spain, the Netherlands, and the United Kingdom. Three groups of older consumers were identified: heavy meat consumers, medium meat consumers, and light meat consumers. The groups differed significantly in several socio-demographics and background characteristics, appetite, protein intake, attitudes towards meat and plant-based ‘meat’ substitutes, and liking of protein sources other than meat. Health and sustainability food choice motives were important determinants for being classified as a medium or light meat consumer compared to a heavy meat consumer whereas food fussiness, sensory appeal, and familiarity were important determinants for being classified as a heavy meat consumer compared to a light meat consumer. Opportunities and barriers to meeting the high protein needs in an environmentally sustainable way and implications for designing dietary strategies to address the unique health and sustainability challenges among older adults in the EU are discussed.

As we age, our taste and smell functions deteriorate. This is thought to contribute to poor appetite, decreased food intake, poorer dietary quality, and the development of undernutrition in older adults. In this study, we evaluated whether poor taste and smell were indeed associated with poor appetite, food intake, dietary quality, and the occurrence of undernutrition.

We recruited 359 Dutch older adults over 65 years old from the large, ongoing Longitudinal Aging Study Amsterdam (LASA). We collected all of our data during a single home visit at the participants’ homes between 2017 and 2018. Taste and smell function were measured with objective standardized tests, and were rated subjectively by the participants themselves. Poor appetite, food intake and dietary quality were assessed with two questionnaires: the Council of Nutrition Appetite Questionnaire (CNAQ) and a Food Frequency Questionnaire (FFQ). Undernutrition was defined as either >5% bodyweight loss over the previous 2 years, or a low BMI.

Of our 359 participants, 9.2% had poor taste, 17% had poor smell, 6.1% had poor appetite, and 2.1% suffered from undernutrition. Various associations were found of poor taste or smell with poor appetite, food intake, or dietary quality, but not with undernutrition. Both self-reported poor taste and smell were consistently associated with poor dietary quality.

Taste and smell impairments may have diverse consequences for appetite, food intake, or dietary quality. However, this does not necessarily translate into undernutrition.

About one in four older adults do not eat enough protein. Providing information to older adults about dietary protein might lead to an improvement in protein intake. To optimally provide this information, it is important to know what older adults already know about dietary protein. We measured the knowledge about dietary protein in almost 2000 community-dwelling older Europeans from five countries. Most older adults knew that dietary protein is important for health and muscles. Fewer older adults knew the correct protein content of foods. However, only few older adults were knowledgeable on the recommended protein intake. Overall, about half of the older population had a poor knowledge. Males, those unable to walk for 5 minutes, those not always making their own food decision, and those with a lower income were more likely to have poor knowledge. Furthermore, large knowledge differences were observed between the five countries. We conclude that the level of knowledge about dietary protein can be improved in about half of the older population. Better communication and information about dietary protein is thus needed and should be targeted to the groups with the poorest knowledge.

The Horizon2020 PROMISS project tackles malnutrition with a specific focus on protein-energy malnutrition.

PROMISS makes use of large-scale databases to understand the relationships between food intake, food characteristics, physical activity, the oral and gut microbiota, and poor appetite, malnutrition and poor health among older adults. Preferences and attitudes of older persons about food intake and physical activity are also taken into account.

Based on the outcomes of this research, PROMISS has developed optimized, sustainable and evidence-based dietary and physical activity recommendations

This newsletter focuses on the recommendations on sustainable protein intake for older people living at home.

Background and Method

Older adults are recommended to sleep 7-8 hours/day. Time in bed (TIB) differs from sleep duration and includes also the time of lying in bed without sleeping. This study was based on cross-sectional analysis of the Healthy Ageing Network of Competence (HANC Study). Physical activity and sedentary behaviour were measured by a tri-axial accelerometer (ActiGraph) placed on the dominant wrist for 7 days. TIB was recorded in self-reported diaries and participants were categorized as “usually”, “sometimes”, or “rarely” meeting the recommended TIB of 7-9 hr/night in the measurement period, corresponding to “≥80%”, “20-79%”, and “<20%” of measurement days, respectively.

Results and Conclusion

341 older adults (median age 81 (IQR 5), 62% women) were included with median TIB of 8hr 21min (IQR 1hr 10min)/day, physical activity level of 2054 (IQR 864) counts per minutes (CPM)/day with 64% (IQR 15%) of waking hours in sedentary behavior. Those who are more active (with average CPM within the highest tertile) are less likely to be categorized as “rarely” complying to 7-9hr TIB (67 % lower risk) when compared to those who are less active (CPM within the lowest tertile of average CPM). Being highly sedentary (≥10 hr/day of sedentary behavior) resulted in over 3 times higher risk to be categorized as “rarely” complying to 7-9hr TIB (relative risk ratio 3.21 (1.50-6.88), p=0.003). For older adults, being physically active and less sedentary was associated with being in bed for 7-9 hours/night for most nights (≥80%). Practical implication of this study is to recommend older adults to be in bed for preferably 7 to 9 hours per night. In order to achieve this goal, clinicians can recommend evidence-based strategies to older adults for promoting adequate TIB and improving sleep quality. Future longitudinal studies are warranted to explore the causal relationship between physical activity, time in bed, and sleep duration. Lower sensitivity of wrist-worn accelerometers to distinguish physical activity at higher intensities needs to be considered and perhaps replaced or coupled with measures from thigh-worn or hip-worn accelerometers.

In order to prevent protein malnutrition in the midst of environmental challenges, this study offers insight into more sustainable ways of increasing older adults’ (≥65) protein intake in Europe.

A choice experiment (n = 2159) was conducted in five European countries (the Netherlands, the United Kingdom, Poland, Finland, and Spain).

The model shows that the majority of older adults accept protein-enriched burgers. Overall they prefer red meat and poultry above plant-based burgers. For red meat and poultry burgers, older adults prefer products with carbon labels indicating a lower environmental impact. Four consumer segments were identified. The largest segment (41%), “Meatlovers”, are not likely to change their red meat and poultry consumption. However, carbon labeling entails some opportunities. “Eco-friendly” consumers (28%) are willing to consume protein from more sustainable sources and herewith constitute the primary target group. “Poultry lovers” (12%) are most likely to shift their protein consumption based on health-related motives. Further research is recommended to identify sustainable protein-rich products for older adults who dislike burgers (19%).

Subsequent consumer profiling indicates that intentions to consume sustainable protein-enriched burgers are associated with gender, country, importance attached to health, sustainability and familiarity, knowledge of protein, and environmental impact. In contrast, financial situation, importance attached to price, convenience, and sensory appeal are less relevant in shaping older adults’ preferences.

Introduction: Short-term metabolic and observational studies reveal that protein intake above the recommended dietary allowance of 0.83 g/kg body weight /day may have positive effects on muscle mass and physical function in old age, but evidence from randomized controlled trials is not clear.

Methods: The PRevention Of Malnutrition In Senior Subjects in the EU (PROMISS) trial evaluates the effect of a personalized protein rich diet on physical function. Some participants are additionally advised to consume protein shortly after usual physical activity. A total of 264 older adults over 65 living at home with a lower protein intake (< 1.0 g/kg body weight/day) from Finland and the Netherlands will be randomized into three study groups; two intervention groups and one control group. Intervention group 1 receives personalized dietary advice in order to increase their protein intake to at least 1.2 g/kg of bodyweight/day. Intervention group 2 receives the same advice as Intervention group 1, and in addition advice to consume protein through protein rich or protein enriched foods within half an hour after performing usual physical activity. The control group receives no intervention. We will investigate the effect of increasing protein intake after 6-months looking if there’s a change in how long a person takes to walk 400-m. Other outcome measures are i.e. changes in a physical performance test, muscle strength and body composition. We also investigate cost-effectiveness by change in health care costs.

Discussion: The PROMISS trial will provide evidence whether increasing protein intake, and additionally optimizing the timing of protein intake, has a positive effect on the course of physical functioning after 6 months among older adults living at home with a lower protein intake.

The Journal of Nutrition

Eating more dietary protein than what is currently recommended is suggested to improve physical functioning and well-being in older adults. However, increasing protein intake is likely to have adverse consequences for the climate if the level of greenhouse gas emissions (GHGE) associated with various protein sources is not considered. Therefore, there is a need to identify changes in the diet of older adults that can increase their protein intake while reducing their diet’s GHGE.

In this study we used diet optimization techniques to identify dietary changes that simultaneously increase protein intake in older adults and reduce their diet’s GHGE. We used dietary data on 1,354 community-dwelling older adults (56-101 y) from the Longitudinal Aging Study Amsterdam cohort to calculate the average intake of 254 food items (e.g. chicken breast) and 25 food groups (e.g. poultry). Starting from this average diet, we modelled several diets by applying nutritional, environmental, and acceptability conditions such as ‘the modelled diet’s GHGE needs to be 50% lower than that of the average diet’. Then we calculated the differences in intakes between the modelled diets and the average diet to determine what and how much change in food intake is needed.

We found that achieving a high-protein diet without considering GHGE resulted in a 5-12% increase in GHGE in men and 9-14% increase in women. To achieve a high-protein diet with a moderate GHGE reduction, meat intake needed to be reduced to the amount recommended by the national food-based dietary guidelines for men but no change in total meat intake was needed for women. Further, a replacement of beef/lamb and processed meat with poultry and pork was needed, as well as increases in whole grains, nuts, and meat/dairy alternatives and decreases in discretionary food products like sweets for both men and women.

In conclusion, meeting the protein requirement of the growing older population with reduced GHGE requires a change in meat type (and quantity for men), an increase in consumption of a variety of plant-proteins, and a reduction in consumption of discretionary food products.

European Journal of Ageing

Diet plays an important role in susceptibility to chronic diseases during the ageing process. However, a poor appetite or ability to eat and its association with physical function have not been explored considerably among community-dwelling older adults. The current study examined whether having an illness or physical condition affecting one’s appetite or ability to eat is associated with body composition, muscle strength, or physical function among community-dwelling older adults. This is a secondary analysis of cross-sectional data from the Age, Gene/Environment Susceptibility-Reykjavik Study (n=5764). Illnesses or physical conditions affecting one’s appetite or ability to eat was assessed with a questionnaire. Those who reported illnesses or physical conditions affecting their appetite or ability to eat were considered to have a poor appetite. A total of 804 (14%) individuals reported having conditions affecting their appetite or ability. The current study found that people with a poor appetite or ability to eat had a significantly lower fat free mass and body mass index, less grip strength and poorer physical function than those without any conditions affecting their appetite or ability to eat. The strong associations with physical function suggests that any condition affecting one’s appetite or ability to eat requires attention.

Gamification means that you use game elements, such as point or badges, to a non-game task, such as a diet journal. Gamification is nowadays applied in many different areas. In this paper we describe the design of a gamified version of an earlier designed diet journal system that is used within the trail of the PROMISS-project. The goal of adding gamification to the existing system is to further stimulate the diet compliance and adherence to the system, but also increase the knowledge about the diet and make using the system more fun. We created 5 different mini-games, testing the participant’s knowledge about the diet. These mini-games were used as a reward for consuming the right amount of protein in a meal. Playing the games with success results in improvements to a cartoon garden displayed on the screen, making the look of the app more attractive. Next to the games, a profile page of the participant was added, as well as achievements for different activities in the app.

Adequate protein intake is required to maintain muscle health, which contributes to the prevention or delay of disability and mortality. At present, the European Food Safety Authority advises older adults to consume at least 0.8 grams of protein per kilogram of body weight (BW). Experts in the field believe that older adults need even more protein (1.0 to 1.2 g/kg BW.) Little is known about the proportion of older adults that does not reach these recommended levels of protein intake.

In this study we estimated the proportion of community-dwelling older adults (≥55 years) that consumed less protein than recommended. We were also interested in whether these proportions differed across subgroups of age, sex, body mass index, education level, living status, appetite and recent weight loss. For example, do women less often meet recommended protein intake levels then men? We used data on 8103 older adults from European and North-American countries.

We found that 22% of the older adults had a protein intake below 0.8 g/kg BW. Nearly half (47%) and three-quarters (71%) of the older adults had a protein intake below 1.0 and 1.2 g/kg BW, respectively. Women, older adults with a higher body mass index and older adults with poor appetite were more likely to have a protein intake below the recommendation. The proportions differed only marginally by subgroups according to age, education level, living status and recent weight loss.

This study shows that a substantial proportion of older adults does not meet the recommended levels of protein intake, which make them at risk for inadequate protein intake and potential health problems. This stresses the need for awareness and for dietary strategies in order to increase protein intake in older adults.

The current dietary guidelines recommend a protein intake of ≥0.8 g protein per kg body weight per day (g/kg BW/d), but experts propose a higher intake for older adults (1.0 to 1.2 g/kg BW/d). Since there are differences in body composition and hormonal milieu between sex and race, protein needs may also differ between men and women or blacks and whites.  It is unknown whether optimal protein intake differs by sex or race.

We aimed to examine sex- and race-specific associations of dietary protein intake with 3- and 6-year changes in muscle mass and gait speed, and the development of mobility limitation during 6 years in US older men and women.

Data were from 2400 community-dwelling men and women aged 70-81 years and living in the areas of Memphis, TN, and Pittsburgh, PA (US), who participated in the Health, Aging, and Body Composition (Health ABC) Study.

We found that a higher protein intake was associated with less muscle mass loss over 3 years in women, specifically black women, but not over 6 years or with a decline in gait speed. In men, protein intake was not associated with changes in muscle mass and gait speed. A higher protein intake was associated with a lower risk of mobility limitation in both men and women, specifically white women. In conclusion, associations between protein intake and physical outcomes may vary by sex and race. Therefore, it is important to consider sex and race in future studies regarding protein needs in older adults.

The outbreak of COVID-19, a new form of coronavirus, and its rapid spread around the world has required the PROMISS project partners to adapt to keep everyone safe and healthy.

  • Our annual PROMISS consortium meeting was held virtually and although we couldn’t meet up face-to-face, we were able to have virtual in-depth discussions and decide effectively on the project’s next steps.
  • Our PROMISS long-term (cost)effectiveness study also had to adapt its final tests to ensure participants’ health and safety. Starting from March 16 2020, the final follow-up measurement was postponed until further notice. Final measurements were resumed in April (through interview by phone) except for the physical measurements. Starting from the beginning of June, the physical measurements at the clinic site were also resumed in both Finland and the Netherlands. Those with no health complaints potentially caused by the coronavirus were allowed to visit the clinic site.

The PROMISS consortium encourages everyone to follow the guidance of the World Health Organisation and government measures taken in our respective countries. For reliable information about the pandemic, please visit only trusted sources among which:

Adequate protein intake is important for the health and physical functioning of older adults. There are indications that the timing of protein intake may influence total protein intake, but evidence is limited so far. Therefore we studied the association between timing of protein intake and the total amount of protein ingested in 739 community-dwelling Dutch older adults (70+), who participated in the Dutch National Food consumption Survey 2010-2012. Participants were interviewed at home by trained dieticians twice, with a mean interval of four weeks about all food and drinks they had eaten the day before. For all foods and drinks consumed, the amount and time of consumption was recorded. For each day we calculated how much protein the participant ingested. If the participant ingested less than 0.8 g protein per kilogram of body weight, protein intake was considered to be low that day.

The results showed that protein intake differed across hours of the day with peaks between 08:30-09:29h (mostly breakfast), 12:30-13:29h (mostly lunch), and 17:30-18:29h (mostly dinner). On the 290 days that protein intake was low, for each hour of the day the average amount of protein ingested was lower compared to the 1188 days with a higher protein intake. This lower intake at either time of day may, however, just reflect a lower food consumption and does not necessarily provide information on the distribution of protein intake over the day. Therefore, we also investigated how much of the total protein was ingested in the morning, midday or in the evening. On days with a low protein intake, a larger part of the total protein intake was ingested in the morning (22%), compared to days with a higher protein intake (17%). If a larger part of total protein was consumed in the morning, there was a higher change that the total protein intake of that day was low. Weaker associations were observed for the part of protein that was ingested midday or in the evening. These results confirm results of other studies on this topic and suggest that timing of protein intake may influence total protein intake. Drawing final conclusions on the effect of timing of protein on total protein intake from our study is difficult. It is important to look in more depth into the timing of protein intake in experimental studies actively manipulating protein intake at different hours of the day, to see if timing of protein intake can be used to increase the likelihood of an adequate protein intake among older adults.

As many older adults do not meet the (current and higher) recommendations, we examined the feasibility (effectiveness and appreciation) of two dietary advice strategies to increase protein intake following either an even distribution of protein consumption over the day (‘even’ strategy) or a peak in protein consumption during one meal moment (‘peak’ strategy).

Older adults aged ≥ 65 years (n=60) who live at home were randomised into one of three groups; two intervention groups (‘even’ or ‘peak’ strategy) and one control group. Over the course of four weeks, participants of both intervention groups received personalised dietary advice and protein enriched food products (such as puddings, rice pudding, coconut water and whey-protein powder) to increase their daily protein intake. The ‘even’ group was advised to consume a maximum of 20 g of protein during each meal or snack moment while the ‘peak’ group was advised to consume at least one daily meal with 35–45 g of protein.

Both intervention groups increased their protein intake after four weeks significantly compared to the control group and participants following the ‘peak’ strategy more often had at least one meal per day very high in protein (≥35 g). Both intervention groups considered the advice to increase protein as (very) clear, and most reported they would (partly) continue following the advice  to increase protein intake.

The ‘even’ and ‘peak’ dietary advice strategies were effective in increasing protein intake in four weeks and both well appreciated by community-dwelling older adults.

As involuntary weight loss in older age is related to functional decline and to mortality, the knowledge about factors affecting body weight is of importance. One factor that may influence body weight in older people is the oral health status. Therefore, we aimed to investigate the longitudinal associations of different oral health characteristics with body weight in community-dwelling older adults.

We used data of 657 community-dwelling older adults aged 55-80 years from the Longitudinal Aging Study Amsterdam (LASA). The first assessment of oral health and body weight took place in 2005/07 and the second in 2015/16. To describe oral health status, aspects relating to teeth, dentures, and oral problems (e.g. bleeding gums) as well as the self-rated oral health were assessed.

The proportions of people being edentulous and wearing dentures increased during follow-up and the proportions of people suffering from oral health problems remained relatively stable over time. About two thirds of the participants rated their oral health status as healthy. In our analyses, only the self-rated oral health status was associated with body weight.

In community-dwelling older adults self-rated oral health may indicate changes in body weight in the long term. Therefore, this simple measure could serve to identify a risk for weight loss and to initiate oral interventions in clinical practice.

The Centre of expertise for Agrotechnology and Biotechnology at the VIVES University of Applied Sciences, Belgium, has gathered extensive expertise on malnutrition among older persons in the PROMISS project. Taking this expertise, VIVES developed specific training and education material for different actors within the practice-oriented research project “Seniorproof”.

For example, an “ambiance box“ was developed to inspire caregivers to decorate a meal attractively. In addition, a taste panel was set up that can help companies and industrial kitchens to develop new food products that are adapted to the preferences and needs of the older persons.

Frailty is a clinical syndrome defined as an increased vulnerability to recover after a health shock. Pre-frailty and frailty are estimated to be present in 42% and 11% of community‐dwelling older adults respectively, and both increase with age. Frail older adults are at increased risk of disability, hospitalisation, care home admission and death. In this study we have used five criteria: muscle weakness, slow walking speed, low physical activity, exhaustion, and unintentional weight loss to define frailty. Malnutrition is central to all these criteria and it might be that a good intake of dietary protein is a viable strategy to change the progression of frailty in older adults by slowing down the progressive loss of muscle mass and physical function. We used data from a study on 700 very old adults that turned 85 years old in 2006/2007 living in North East England and we followed them until they were 90. Protein intake was estimated with a 24-hour multiple pass recall (people were asked what foods and drinks were consumed in the past 24 hours) on two different occasions in 2006/2007. We found that participants with higher protein intake were less likely to become frail if they were pre-frail to begin with. This was also true for those who had protein intake higher than 0.8 or 1.0 grams per kilogram of adjusted bodyweight. Energy intake seems to play an important role in this relationship between protein and frailty.

Malnutrition is a state of energy or protein deficiency, which causes measurable changes in body functions. Among older people malnutrition is widespread and is associated with frailty, functional decline and poor quality of life. Malnutrition can be caused by multiple different factors such as disease-related, functional, psychological, and socio-economic aspects. Moreover, it is assumed that the oral health status plays a role in the development of malnutrition, as mastication and insalivation are important steps in eating and digesting. Therefore, the aim of our study was to investigate the association of different oral health characteristics and the development of malnutrition during 9-years in community-dwelling older adults.

The data used were from the Longitudinal Aging Study Amsterdam (LASA). We included participants aged 55-80 years without malnutrition at the beginning of the investigation. To describe oral health status, aspects relating to teeth, dentures, oral hygiene and oral problems (e.g. bleeding gums) as well as the self-rated oral health were assessed.

Of the 19 investigated oral health characteristics, toothache while chewing was identified to increase the risk of devolving malnutrition. In addition, for a poor self-rated oral health and the feeling of a dry mouth in combination with having no teeth we found indications that they might play a role in the long-term development of malnutrition. Regarding strategies to prevent malnutrition in older people these three aspects are of specific interest as they are modifiable and can be easily assessed by self-reports.

A common phenomenon amongst older adults is a decline in appetite, which is thought to contribute to the occurrence of undernutrition. This decline in appetite is called: “Anorexia of Aging”. Many factors are thought to contribute to anorexia of aging, including a decrease in smell function as we become older. A deteriorating sense of smell is believed to diminish eating pleasure and change people’s food-related choices. This would then lead to lower food intake and ultimately undernutrition.
In this study, we evaluated whether sense of smell was associated with appetite, weight change and BMI. In other words: do people with poorer sense of smell also report poorer appetite, suffer more weight loss and have a lower BMI? In 2012-2013, we used a commercially available smell test (the 40-item UPSIT test) to assess sense of smell in 824 Dutch older adults, aged 55-65 years old. All these older adults were also enrolled in the larger LASA-study which studies the consequences of aging in the Netherlands. In addition to the results of the smell test, we made use of the self-reported appetite, weight, and BMI, as well as many other variables measured by LASA.
Ultimately, 673 participant had correctly filled out the UPSIT-test and were included in this study. No association between sense of smell and appetite or weight change could be found. However, there was an association between poorer sense of smell and lower BMI in older adults who smoke, but not in older adults who do not smoke.
This means that poor sense of smell in older adults who also smoke might be a vulnerable group when it comes to undernutrition.

Considering today’s environmental challenges such as climate change and biodiversity loss, sustainable dietary strategies are needed to meet the high protein requirement of a growing aging population. This study investigated the readiness of older adults to accept the consumption of the following alternative, more sustainable protein sources: plant-based protein, insects, single-cell protein, and in vitro meat. We used data from a survey that was conducted among 1825 older adults aged 65 years or above living in the United Kingdom, the Netherlands, Poland, Spain, and Finland.

Dairy-based protein was the most accepted protein source among older adults, with 75% of the respondents reporting dairy to be acceptable or very acceptable. When it came to alternative, more sustainable protein sources, 58% of the respondents reported to accept plant-based protein, 20% reported to accept single-cell protein, 9% reported to accept insect-based protein, and 6% reported to accept in vitro meat-based protein. We found that fussy eaters were less likely to accept eating alternative, more sustainable protein sources. Older adults who were more active in sustainable food consumption (e.g. purchases organic food) and who were highly educated were more likely to accept eating alternative, more sustainable sources. Valuing health, sensory appeal, and price when making food choices, as well as gender and country of residence were found to influence acceptance, although not consistently across all the protein sources.

This paper concludes that a relatively high acceptance of plant-based protein sources provides an opportunity to increase protein intake in an environmentally sustainable way in EU older adults. More research is needed to determine ways to increase acceptance of more innovative, technology-driven protein sources such as single-cell protein and in vitro meat among older adults.

Frailty can be described as a fragile health state that makes a person very vulnerable for health problems. Frail older persons are at higher risk for developing mobility problems, becoming institutionalized and losing independence. For older adults and their families, the possibility to postpone or prevent the development of frailty is likely highly desirable.

Diet is one of the modifiable factors that are supposed to contribute to the prevention of frailty in older adults. Moreover, previous studies have shown that many older adults consume a diet that is of insufficient quality (i.e., their diet does not fully conform to national dietary guidelines) or that is low in protein. We investigated whether poor diet quality and low protein intake would increase the risk of developing frailty in the future.

The data are from the Health, Aging, and Body Composition (Health ABC) Study, which consists of community-dwelling older adults aged 70 years and over, who live in the areas of Memphis, TN, and Pittsburgh, PA (USA).

We found that older adults with a poor-quality diet had a higher risk of developing frailty compared to older adults with a good-quality diet. We found no relationship between protein intake and risk of frailty. In conclusion, our study suggests that it is important to adhere as much as possible to the national dietary guidelines for older adults to postpone or prevent the development of frailty.

We aimed to determine the contribution of protein intake, and the interaction between protein intake and physical activity, to the transition between disability free and disability using the Newcastle 85+ Study. We included more than 700 older adults living in the community and turning 85 in 2006/2007 and we followed them until 90 years of age. Protein intake was estimated with a 24-hour multiple pass recall (people were asked what foods and drinks were consumed in the past 24 hours) on two different occasions in 2006/2007. Study participants were also asked about their ability to perform 17 activities of daily living (ADL) (able to get in and out of a chair, cut own toenails, manage own medications, etc.) in 2006/2007, and after 18, 36 and 60 months. A simple score was derived by summing the number of ADLs that the participant had difficulty with and a score >1 was considered as disability. We found that an increase in protein intake, especially ≥0.8 or 1g of protein per kg of adjusted body weight per day (g/kg aBW/d) decreased the likelihood of developing disability. An average 85-year-old with protein intake <1g/kg aBW/d was expected to spend 0.86 years disability free and 3.63 years disabled over 5 years while another participant with ≥1.0 g/kg aBW/d was expected to spend 1.58 years disability free and 3.01 years disabled. We also found that those physically active and with a good protein intake were less likely to transition from disability-free to disability than those within the same physical activity level but with worse protein intake. This means that higher protein intake, especially in combination with higher physical activity may delay the incidence of disability in very old adults.

In this paper we introduce a system that uses persuasive communication to stimulate the participants of the PROMISS project to be adherent to their diet advice. We have done literature research towards the different personalization strategies that can be used for persuasive communication. In order to personalize the messages that are send by the system, user characteristics such as gender and personality traits can be used. Furthermore, the design of the system is tailored to the elderly target group. Existing literature towards design principles for elderly is consulted during the design process.

We have first created a prototype of the system and we evaluated this prototype during a pilot study with seven participants. From this pilot we learned more about how the users perceive the system, which gave us insights that are used to improve the system. One important remark made by the participants was about the limited added value of the system in their diet. Such remarks are taken into account for the next version of the application. Furthermore, we extended the requirements of the system with input from the dietitians from PROMISS, to take into account how the diets will be designed in the next trial of the PROMISS project. We have briefly evaluated the new design with participants of the pilot, who were very enthusiastic about the changes made. The system described in this paper will be used in the next trial of the PROMISS project.

Prof. Marian de van der Schueren, our PROMISS member from ESPEN (European Society for Clinical Nutrition and Metabolism), is spreading the word in the Netherlands on the importance of increasing protein intake for older adults.

“Stay fit: eat more protein!” published in a magazine for older people (KBO-PCOB Magazine) includes 7 robust tips from our PROMISS partner on how to ensure you’re getting enough protein and also lists 25 foods rich in protein such as tenderloin, salmon, milk, eggs or walnuts.

Addressing an even wider audience in the NRC (Dutch national newspaper), “Ageing healthy with proteins” also focuses on why protein is important for older people: “Proteins are essential for preserving muscle mass, resilience and your mental state”, explains Prof. de van der Schueren.

European older adults have been studied according to their appetite and protein intake profiles, and the relevant dietary and physical activity behavioural determinants were identified. A survey with 1,825 older adults aged 65 years or above in five European countries (Netherlands, United Kingdom, Finland, Spain and Poland) was conducted in June 2017.

Older adults with a poor appetite and lower level of protein intake is characterized by a larger share of people aged 70 years or above, living in the UK or Finland, having an education below tertiary level, who reported some or severe financial difficulties, having less knowledge about dietary protein and being fussier about food. This group also tends to have a higher risk of malnutrition in general, oral-health related problems, experience more difficulties in mobility and meal preparation, lower confidence in their ability to engage in physical activities in difficult situations, and a lower readiness to follow dietary advice. Therefore, effective dietary strategies to increase protein intake should take into account sensory properties, familiarity, affordability, accessibility and convenience.

Consumption of certain foods at a certain moment of the day and physical activity level or pattern were associated with a lower risk of having lower protein intake. Low level of physical activity emerged as a risk factor for having a lower protein intake in older adults with poor appetite, and vigorous physical activities between lunch and dinner were associated with a lower risk in older adults with good appetite.

This study provides an overview and highlights the similarities and differences in older adults’ profiles, as well as the challenges in promoting healthy ageing regarding protein intake. Recommendations for optimal dietary and physical activity strategies to prevent protein malnutrition were derived, discussed and tailored according to older adults’ profiles.

Sarcopenia is a progressive loss of muscle mass and muscle strength that may lead to disability, falls, and hospitalisation. The very old, those aged 85 years and older, are the fastest growing age group in most western societies and are at especially high risk of sarcopenia. Onset of sarcopenia may be partly explained by diet. Therefore, we aimed to explore the role of dietary patterns and protein intake in the risk of sarcopenia over 3 years. Our study, the Newcastle 85+, was based in North East England, and involved more than 750 people aged 85 years old. These participants had their diet estimated by a 24 hour multiple pass recall (people are asked what foods and drinks they consumed in the past 24 hours) on two different days of the week and from this, dietary patterns were derived. Sarcopenia was measured over 3 years according to a muscle mass index, gait speed and grip strength. We identified three dietary patterns: ‘Low Red Meat’, ‘Traditional British’ and ‘Low Butter’ that varied by unsaturated fat spreads/oils, butter, red meat, gravy and potato consumption. We found that very old adults who had a dietary pattern high in foods characteristic of a traditional British diet (high butter, red meat, gravy and potato consumption, and high fat and energy intake), especially compared to a low butter dietary pattern (high in unsaturated fat spreads/oils, fibre, percentage of energy from protein and starch) had an increased risk of sarcopenia even when overall protein intake was good. These results add to the limited literature on the role of the whole diet in sarcopenia in very old adults.

Over 20 million older citizens are at risk of protein malnutrition in Europe, whose consequences on health are serious and often irreversible.

Based on the outcomes of our research, PROMISS will develop optimised, sustainable and evidence-based dietary and physical activity strategies, which are currently tested in the Netherlands and Finland for effectiveness and cost-effectiveness in a long-term intervention study.

The project will show whether these strategies together with new food concepts and products will prevent malnutrition and support active and healthy ageing.

Our PROMISS partner, Christine Yung Hung from the University of Ghent, Belgium, presented PROMISS project results at the 168th EAAE Seminar on 7 February in Uppsala, Sweden.

The seminar addressed the questions of behavioural perspectives in agricultural economics and management by an exchange of current ideas and knowledge related to the effect of human personal characteristics, values, rationality, attitudes, emotions, goals, cognition etc. on production and consumption decisions.

Christine Yung Hung’s presentation contributed to the theme by presenting some of PROMISS’ WP4 results under the heading “Behavioural Determinants Shaping Protein Intake in European Older Adults”. PROMISS’ WP4 aims to quantify specific attitudes and preferences of older adults, as food consumers, with regard to dietary and physical activity characteristics and daily patterns according to appetite and malnutrition strata, and was therefore an excellent fit for the seminar’s overall theme.

Sharing insights these insights will help the advancement of the academic field but may also contribute to the formulation of efficient and effective public and private policy schemes, advisory support, and measures to affect production and consumption choices.

Daily sedentary time and physical activity among Dutch older adults

Higher physical activity is associated with lower chronic disease risk among older adults. However, less is known about the optimal balance between daily physical activity and sedentary time and their correlates among older adults. In this study van Ballegooijen et al from the VU University in Amsterdam objectively measured physical activity patterns and assessed its correlates in a large sample of older Dutch adults. In addition, they examined different combined profiles of sedentary time and physical activity across strata of sex, age, education and BMI groups.

They made use of cross-sectional data from 1,201 participants of the 2015-2016 examination of the Longitudinal Aging Study Amsterdam, a population-based cohort of older Dutch adults. The mean age was 71 year and 51% were women Participants were instructed to wear an Actigraph accelerometer for 7 consecutive days at the right hip. Time spent in sedentary (<100 counts per minute [cpm]), light (100-2020 cpm), and moderate and vigorous activity (MVPA) ≥2020 cpm) were calculated and compared across age, sex, education and BMI groups.

The authors conclude that the majority of wake time was spent sedentary 65% followed by light (33%), and moderate to vigorous physical activity (2%). Higher age and higher BMI were related to more time spent sedentary, while female sex and lower education were related to less time spent sedentary. The combination of high sedentary time and low physical activity was significantly associated with higher age, higher BMI, and slower walking speed compared to the combination of low sedentary time and high physical activity. This suggests that increasing light activity might be an effective and feasible strategy in older persons to reduce sedentary time.

In a nutshell, these are the key findings of the study:

  • Dutch older adults spend on average 65% of their waking time sedentary.
  • Older adults’ sedentary time differs by age, sex, education and BMI groups.
  • The combination of high sedentary time and low physical was associated with higher age, higher BMI, and slower walking speed compared to the combination of low sedentary time and high moderate to physical activity.

Protein shakes don’t count: Why older adults should eat real food

NBC News publishes an article on protein mentioning the results of the study performed by PROMISS researcher Nuno Mendonca.

“Older adults need to eat more protein-rich foods when they’re trying to lose weight, dealing with a chronic or acute illness, or facing a hospitalization, according to a growing consensus among scientists.”

The article mentions the results of a study published in 2017 by PROMISS researcher Nuno Mendonca and followed nearly 2,000 older adults over six years: “People who consumed the least amount of protein were almost twice as likely to have difficulty walking or climbing steps as those who ate the most, after adjusting for health behaviors, chronic conditions and other factors.”

In order to preserve muscle mass and physical function, it is important to consume a sufficient amount of protein with food. However, research shows that around 50% of adults aged 65 years and older consume less than 1.0 gram/kg body weight of protein per day.

The practical question is how to calculate if you fall in this case?

PROMISS researchers set up a short food questionnaire, named the Protein Screener 55+ or Pro55+ to provide you with the probability for low protein intake in community-dwelling older people.

The Pro55+ finally consists of questions on weight and height, and the consumption (amount on average day or frequency in 4 weeks) of: slices of bread (number); glasses of milk (number); meat with warm meal (portion size); cheese (amount and frequency); dairy products (like yoghurt) (frequency); egg(s) (frequency); pasta/noodles (frequency); fish (frequency); and nuts/peanuts (frequency).

Validation tests proved that the Pro55+performs well in discrimination persons with a low and high protein intake.

Our conclusion is that the Pro55+ can be used to validly screen for protein intake below 1.0 gram/kg body weight of protein per day in community-dwelling older adults.

Available in English, its online version can be found at www.proteinscreener.nl.

PROMISS encourages such tool to be up-taken and used in other countries, and in other languages as well.

Healthcare and communications professionals will bring PROMISS-results to the older adults

The world is facing a situation without precedent: we will soon have more older people than children, and more people at very
old age than ever before. When looking at nutrition in old age, it strikes that more than 90 % of older people in Europe are living at home, and a very poor appetite is reported by 10–15 % of them, which, consequentially, causes malnutrition, and a ‘cascade’ of deteriorated body functions and illnesses; muscle loss, cognitive decline, weak immune systems and slowed wound healing.

The PROMISS project intends to tackle malnutrition, and Professor Marjolein Visser from Vrije Universiteit Amsterdam explains that, in order to design concrete and tailored solutions, optimal protein intake combined with physical activity at certain time points release extra positive effects on ageing. We should however not be left alone in improving our nutrition: the support by healthcare professionals is key.

Press Release – March 2018

Across Europe, one out of five older adults living at home is malnourished, or at risk of protein-energy malnutrition. Improving protein intake might prevent malnutrition.

Many older persons today do not meet the current Recommended Dietary Allowance (RDA) of protein intake, which may lead to mobility limitations, loss of muscle strength, and increases the risks of chronic protein-energy malnutrition. There is increasing evidence that adequate protein intake is crucial in old age, which makes recognition of low protein intake key, and interventions to prevent malnutrition essential.

These are the issues at the core of the PROMISS research, and you can read about this in our first press release.

PROMISS and the Health ABC Study

The Health, Aging and Body Composition (Health ABC) Study is one of the longitudinal studies contributing to work package 1 of PROMISS. The Health ABC cohort consists of 3,075 black and white US older adults aged 70 years and over, who were generally well-functioning at baseline. The main focus of the Health ABC study is to determine risk factors for functional decline and loss of independence in healthier older people.

 Since the start of PROMISS in April 2016, several researchers have used the Health ABC data to investigate associations of dietary intake with appetite, malnutrition and mobility limitation in US older adults. In the first paper, entitled Protein intake and mobility limitation in community-dwelling older adults: the Health ABC Study, it was hypothesized that older adults with low protein intake would have a greater risk of developing mobility limitations than those with higher protein intake. The results confirmed the hypothesis: it was shown that older adults with a lower protein intake (<0.7 and 0.7-<1.0 kg/kg body weight/d) had a higher risk of developing mobility limitations in the following 6 years compared to older adults with the highest protein intake (≥1.0 g/kg body weight/d).

The second paper, entitled Poor appetite and dietary intake in community-dwelling older adults, focused on differences in food intake in community-dwelling older adults with different appetite levels. This study showed that 21.8% of the participants had a poor appetite. Those participants consumed less protein, dietary fiber, whole grains, fruits and vegetables, but consumed more dairy foods, fats, sweets and sodas compared to the participants with a very good appetite.

The association between diet quality and protein-energy malnutrition was investigated in the third paper, entitled Prospective associations of poor diet quality with long-term incidence of protein-energy malnutrition in community-dwelling older adults: the Health, Aging and Body Composition Study.” This study showed that the majority of the participants consumed a diet of insufficient quality and that 40% of the participants had a protein intake below the recommended daily intake. Furthermore, in 4 years almost 25% of the participants developed protein-energy malnutrition. It was observed that a higher protein intake may reduce the risk of developing persistent protein-energy malnutrition.

Researchers of work package 1 of PROMISS are currently working on a two other studies by using data from the Health ABC Study. In the first one, those data will be used in a multi-cohort paper on determining the prevalence of low protein intake in community-dwelling older adults. In a second paper, the association between poor diet quality and the risk of developing frailty in (initially non-frail) community-dwelling older adults will be investigated.

 

Combining physical activity and functional tasks in older age

Part of the work carried out in the PROMISS project is based on the HANC study. HANC is an ongoing large-scale European project between 8 Danish and German entities. Currently, 560 older adults (average 82.7 years old) with mobility impairment have a baseline assessment from 12 different domains (e.g. physical activity and sedentariness, sleep, muscle function, environmental characteristics). Assessment involve 7-day measurement by wrist-worn accelerometers, which contributes especially to PROMISS WP2 on reporting physical activity, sedentary behavior in older adults and can be compared with other cohorts in the PROMISS consortium.

Li-Tang Tsai and Paolo Caserotti, from the University of Southern Denmark, have reported preliminary results of accelerometer data from 2 cohorts: data from HANC suggested that older people with a combination of low activity count and low variability of activity throughout the week (meaning their activity level is stable throughout the weak) performed worst in functional tasks (SPPB: walking speed, chair stand, balance test) while those with high activity count and high variability of activity throughout the week performed best in the same tasks.

The team is currently working on a manuscript which will describe and compare accelerometer data from 5 cohorts within PROMISS consortium. This work will be an input to the symposium on “The impact of appetite, low protein, and physical activity on function: the PROMISS study” in the 24th Nordic Congress of Gerontology on 2-4 May in Oslo, reporting on “Associations between accelerometer-assessed physical activity, sedentary behavior, and handgrip strength among older adults across Europe and USA”.

Various issues influence our appetite and metabolism, and gut bacteria have a role to play in there. A previous research project focused on one of the substances made by gut bacteria, namely butyrate, which is thought to improve body weight, appetite, and glucose- and fat-metabolism.

The project demonstrated in mice that most effects of butyrate on body weight and metabolism were actually not caused by butyrate directly.  Rather, butyrate caused a decrease in appetite and food intake, which in turn caused the improvements in body weight and metabolism. Because of its effects on appetite, the researchers concluded that butyrate might potentially be used as weight-losing drug.

PROMISS would like more research to be carried out. The fact that that project was performed in mice, not in human beings, cannot make us jump to the conclusions that their results would be similar in human beings.  The PROMISS experience is that effects in mice (promising as they might be) are often not as remarkable in humans. Furthermore, even if butyrate would work as effective in humans as it does in mice, we think that it might only work in specific individuals.

Malnutrition is a critical issue, with a direct impact on older people’s quality of life. In Europe alone, about one out of 5 older people living at home is malnourished or at risk of malnutrition.

Preventing malnutrition is urgent for the whole society, for older generations of today as well as those of tomorrow.

Last February 2016, the European Innovation Partnership on Active and Healthy Ageing (EIP AHA) opened new calls inviting organisations to get involved in developing, promoting or deploying innovative solutions and ecosystems for active and healthy ageing. The Call for Commitments targeted innovative solutions for active and healthy ageing.

The call received a strong support. The European Commission has recorded over 850 commitments from 28 Member States (and beyond) while 78 Reference Site applications (from 22 Member States) were submitted, representing regional and national alliances of stakeholders invested in the scaling up of innovation for active and healthy ageing.

We are very happy that the commitment submitted by PROMISS has been accepted, letting us become one of the official members of the EIP AHA, and more precisely of the A3 action group on Functional decline and frailty.
