Continuing Care Retirement Communities

Abstract Malnutrition and sarcopenia are present in parallel in older adults and characterized by a combination of inadequate nutrient intake and decreased muscle mass, strength, and/or function. The presence of both conditions has been termed Malnutrition-Sarcopenia Syndrome (MSS) and is associated with negative health outcomes. The objective of this correlational study was to identify the prevalence and factors associated with the malnutrition-sarcopenia syndrome among older adults living in continuing care retirement communities. A convenience sample of 104 older adults living in CCRCs participated in this study. Muscle mass, strength, and function were measured using bioimpedance analysis, Jamar digital hand dynamometer, and the Short Physical Performance Battery test, respectively. Physical activity, sedentary time, and nutritional status were measured using ActiGraph GT3X and Mini Nutritional Assessment, respectively. Questionnaires were used to measure self-efficacy for exercise and goal congruence for physical activity and protein intake. Of the 104 participants, 37 (35.2%) had sarcopenia, 19 (18.1%) had malnutrition, and 14 (13.5 %) had MSS. Compared with those without MSS, older adults with MSS were more than two times more likely to have a sedentary lifestyle (Odd ratio, 2.028; 95% confidence interval, 2.012–2.044). Findings showed that sarcopenia, malnutrition, and MSS are prevalent in older adults living in continuing care retirement communities. Older adults should be screened and assessed for both malnutrition and sarcopenia. The results also suggest that decreasing the sedentary time could help in preventing MSS among older adults living in continuing care retirement communities.

Abstract Background Older adults are recommended to sleep 7–8 h/day. Time in bed (TIB) differs from sleep duration and includes also the time of lying in bed without sleeping. Long TIB (≥9 h) are associated with self-reported sedentary behavior, but the association between objectively measured physical activity, sedentary behavior and TIB is unknown. Methods 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. Sedentary behavior was classified as < 2303 counts per minute (cpm) in vector magnitude and physical activity intensities were categorized, as 2303–4999 and ≥ 5000 cpm in vector magnitude. TIB was recorded in self-reported diaries. Participants were categorized as UTIB (usually having TIB 7–9 h/night: ≥80% of measurement days), STIB (sometimes having TIB 7–9 h/night: 20–79% of measurement days), and RTIB (rarely having TIB 7–9 h/night: < 20% of measurement days). Multinominal regression models were used to calculate the relative risk ratios (RRR) of being RTIB and STIB by daily levels of physical activity and SB, with UTIB as the reference group. The models were adjusted for age, sex, average daily nap length and physical function. Results Three hundred and fourty-one older adults (median age 81 (IQR 5), 62% women) were included with median TIB of 8 h 21 min (1 h 10 min)/day, physical activity level of 2054 (864) CPM with 64 (15) % of waking hours in sedentary behavior. Those with average CPM within the highest tertile had a lower RRR (0.33 (0.15–0.71), p = 0.005) for being RTIB compared to those within the lowest tertile of average CPM. Accumulating physical activity in intensities 2303–4999 and ≥ 5000 cpm/day did not affect the RRR of being RTIB. RRR of being RTIB among highly sedentary participants (≥10 h/day of sedentary behavior) more than tripled compared to those who were less sedentary (3.21 (1.50–6.88), p = 0.003). Conclusions For older adults, being physically active and less sedentary was associated with being in bed for 7–9 h/night for most nights (≥80%). Future longitudinal studies are warranted to explore the causal relationship sbetween physical activity and sleep duration.
