Summary: This study examines the potential associations between dietary branched-chain amino acids (BCAAs) and physical function in the elderly Chinese population. The results show that a higher intake of BCAAs is positively associated with increased handgrip strength, shorter times for 4-m fast walking, and repeated chair rises. Individuals with higher BCAA intake also have a reduced risk of developing low muscle strength and low physical performance.

Summary: This study investigated the relationship between objectively measured sleep duration and physical function in older adults, finding a positive association between sleep duration and grip strength but no significant associations with other physical function outcomes. Lengthening sleep duration may help enhance grip strength in older adults, suggesting implications for improving health through better performance in specific physical functions. Further research should explore the mechanisms underlying the relationship between sleep duration and physical function in older adults.

Summary: This study aimed to investigate the relationship between metabolic syndrome, sleep duration, and mild cognitive impairment (MCI) in community-dwelling older Chinese adults. The findings revealed a significant association between long sleep duration (>10 hours) and increased risk of MCI in older adults with metabolic syndrome. Preventive measures for MCI may be more effective in individuals with metabolic syndrome and long sleep duration.

Summary: This study investigated the association between dietary protein intake and change in physical performance among Chinese community-dwelling older adults. Results showed that total and animal protein intakes were not associated with 4-year change in physical performance, while higher plant protein intake was linked to less decline in physical performance in females.

Summary: This study examined the associations between single essential metals and essential metal mixture with fasting plasma glucose (FPG) levels in Chinese elderly people. The results showed that urine vanadium (V) and magnesium (Mg) were negatively associated with FPG levels, while urine selenium (Se) was positively associated. The essential metal mixture displayed a linear dose-response relationship with reduced FPG levels, with magnesium having the largest contribution.

Summary: A larger kyphosis angle is independently associated with poorer physical performance in community-dwelling older adults. This association is unidirectional, indicating that an increase in kyphosis angle is related to a decrease in physical performance, but physical performance does not affect kyphosis progression.

Summary: Experimental evidence suggests that neonicotinoids (NEOs) exposure is associated with lipid accumulation and increased leptin levels. However, the relationship between NEOs exposure and dyslipidemia in humans is unclear. We detected NEOs and their metabolites in urine samples from individuals randomly selected from the Yinchuan community-dwelling elderly cohort. Our findings reveal a positive association between NEOs exposure and dyslipidemia risk, with certain NEOs and their metabolites being major contributors.

Summary: The study found that adhering to physical activity guidelines was associated with lower mortality risk in both stroke survivors and controls, with a dose-response relationship. In stroke survivors, physical activity was more effective in reducing risk among younger individuals.

Summary: This study aimed to investigate the association between nutritional status and sleep quality in Chinese community-dwelling older adults. The results showed that there was a close association between nutritional status and sleep quality in older adults, and well-nourished individuals were less likely to have sleep disorders.

Summary: This study examined the impact of sleep duration on cognitive performance in older adults in China. The findings revealed a U-shaped relationship between sleep duration and the risk of cognitive impairment. Both short and long sleep durations were associated with an increased risk of cognitive impairment. Moderate sleep duration may be a possible strategy to prevent cognitive decline.

Summary: Previous studies have explored the relationship between single essential metal elements (EMEs) and sleep quality in older adults, but the impact of the EME mixture on sleep quality is not well understood. This study examined the associations between single EMEs and the EME mixture and sleep quality in older adults living in Chinese communities. The results showed that Mo, Sr, and Mg were negatively associated with poor sleep quality, both individually and as part of the EME mixture. The EME mixture in urine was found to be associated with decreased odds of poor sleep quality, with Mo being the most significant contributor. Further research is needed to better understand the relationship between multiple EMEs and sleep quality.

Summary: A U-shaped association was found between sleep duration and subjective cognitive complaints (SCCs) in Chinese elderly, with the least association observed at 8 hours of sleep. Both longer and shorter sleep durations than 8 hours were linked to worse SCCs.

Summary: This study aimed to explore the prospective associations between sleep duration trajectories and all-cause mortality among Chinese elderly. The results showed that moderately and rapidly increased sleep duration trajectories were associated with higher subsequent mortality in Chinese elderly. Furthermore, individuals who reported sleep exceeding 9 hours may be at high risk for all-cause mortality.
