“…There was a notable increase in the rates of smoking and a decline in the proportion of population with formal schooling over the study time period, which may have negatively impacted and cognitive performance and confounded the relationship between body composition and cognition. 30 , 31 These environmental factors may confound the association between MAMC and cognitive function, as smoking and lower education levels are associated with cognitive decline. 32 However, higher MAMC was associated with better global cognitive function even when controlling for environmental variables, with no differences between sex ( Table 1 ), suggesting these associations may be independent of behavioral factors.…”

Background Dementia affects 55 million people worldwide and low muscle mass may be associated with cognitive decline. Mid-arm muscle circumference (MAMC) correlates with dual-energy Xray absorptiometry and bioelectrical impedance analyses, yet are not routinely available. Therefore, we examined the association between MAMC and cognitive performance in older adults. Methods We included community-dwelling adults ≥55 years from the China Health and Nutrition Survey. Cognitive function was estimated based on a subset of the modified Telephone Interview for Cognitive Status (0-27, low-high) during years (1991, 1993, 1997, 2000, 2004, 2006, 2009, 2011, 2015, 2018). A multivariable linear mixed-effects model was used to test whether MAMC was associated with rate of cognitive decline across age groups and cognitive function overall. Results Of 3702 adults (53% female, 63.2 ± 7.3 years), mean MAMC was 21.4 cm ± 3.0 and baseline cognitive score was 13.6 points ±6.6. We found no evidence that the age-related rate of cognitive decline differed by MAMC ( P = .77). Declines between 5-year age groups ranged from −.80 [SE (standard error) .18] to −1.09 [.22] for those at a mean MAMC, as compared to −.86 [.25] to −1.24 [.31] for those at a 1 MAMC 1 standard deviation above the mean. Higher MAMC was associated with better cognitive function with .13 [.06] higher scores for each corresponding 1 standard deviation increase in MAMC across all ages. Conclusion Higher MAMC at any age was associated with better cognitive performance in older adults. Understanding the relationship between muscle mass and cognition may identify at-risk subgroups needing targeted interventions to preserve cognition.

Regional and Geographical Disparities in Body Mass Index (BMI) Among Chinese Older Adults: The Chinese Longitudinal Healthy Longevity Survey

et al. 2020

This study examined the regional and geographical disparities in body mass index (BMI) among Chinese older adults. Using panel data from the Chinese Longitudinal Healthy Longevity Survey, participants included 3,740 older adults (age ≥ 65 years) who answered all three waves of the survey (2009–2014). Sex-stratified and multistate Cox regression was used to examine the disparities in BMI change. Results showed that both older males and older females who resided in the central-south had lower rates of weight change from nonobese to obese, compared with those from the east. Older females from urban regions had higher rate of weight change from nonobese to obese, compared with rural participants (hazard ratio [HR]: 1.35, 95% confidence interval [CI] = [1.13, 1.60]; p < .01). However, there were no disparities between urban and rural areas among older males ( p > .05). These results provided practical implications for regional and geographical disparities in BMI among Chinese older adults.
