Bedingt durch den demographischen Wandel in Europa mit einem steigenden Anteil der älteren Bevölkerung wird es immer wichtiger, dass ältere Menschen in ganz Europa gesund und aktiv bleiben. In Europa sind zwischen 13,5% und 29,7% der älteren Menschen, die zu Hause leben, unterernährt oder es besteht das Risiko einer Protein-Energie-Mangelernährung. PROMISS hat sich zum Ziel gesetzt, die Proteinmangelernährung bei Senioren untersuchen und ihr letztendlich vorzubeugen. Damit trägt PROMISS zur Verbesserung des aktiven und gesunden Alterns bei.

PROMISS Newsletter #4 – Recommendations on sustainable protein intake
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.

- Our food choices can make a difference in coping with climate change.
- Acceptability of protein sources among older persons in Europe

Associations between Objectively Measured Physical Activity, Sedentary Behaviour and Time in Bed among 75+ Community-dwelling Danish Older Adults

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.
