Summary: The study found an independent association between physical frailty and social activity, including social participation and engagement. In particular, exercise circle activity was strongly associated with physical frailty, and the strength of the relationship between social engagement and physical frailty varied with age, with a stronger association in older adults.

Summary: The study suggests that increasing step count is associated with better hippocampal volume, and moderate-to-vigorous physical activity (MVPA) is associated with attention-processing speed in individuals with T2D. People with T2D who are receiving insulin therapy may benefit more from MVPA in terms of cognitive function.

Summary: The study aimed to investigate the association of water turnover and total energy expenditure with physical activity and body composition in Japanese preschool children. Results showed that WT and TEE were moderately positively correlated with body weight, fat-free mass, and exercise duration.

Summary: The association between alcohol consumption and dementia in Japanese was investigated using repeated alcohol assessments. Non-drinkers and regular drinkers with alcohol consumption of >= 450 g per week had a higher risk of disabling dementia compared to light drinkers. Long-term abstinence, former drinking, and regular heavy weekly consumption of >= 450 g were also associated with increased risk of dementia.

Summary: This study evaluated the association between soy product and isoflavone intake and the risk of disabling dementia. The results showed that total soy product intake was not associated with the risk of disabling dementia, but natto intake may contribute to reducing the risk in women.

Summary: This study aimed to investigate the potential effect of dietary diversity on the risk of disabling dementia in a nationwide large-scale cohort of the Japanese population. The study found that dietary diversity was inversely associated with disabling dementia among women, but there was no significant association among men.

Summary: This study used data from the UK Biobank to investigate the association between cancer status and the risk of dementia. The results showed that cancer patients had a lower risk of dementia, especially in those with cancers in the male genital system. Non-melanoma skin cancer and prostate cancer were also associated with a reduced risk of dementia.

Summary: This study found a positive association between vigorous physical activity and life satisfaction among adolescents aged 11-15. Both boys and girls who engaged in more frequent vigorous physical activity per week were more likely to have higher life satisfaction. In addition, more hours of vigorous physical activity were also associated with better life satisfaction.

Summary: This study aimed to explore the individual and joint effects of particulate matter PM2.5 and physical activity (PA) on physical function (PF). The results showed that PM2.5 was negatively associated with PF, while PA was positively associated with PF. Physical activity attenuated the adverse effects of air pollution on PF.

Summary: In high-pollution areas, there is an interaction between physical activity and air pollution in their associations with brain volumes. Physical activity is associated with beneficial outcomes in gray matter volume and white matter hyperintensity volume, while air pollution is associated with detrimental outcomes in gray matter volume. The associations between air pollution and white matter hyperintensity volume are exacerbated by physical activity, and the beneficial associations of physical activity with white matter hyperintensity volume are attenuated by air pollution.

Summary: This study found that multiple adverse childhood events are associated with worse psychomotor speed and verbal fluency in later life, especially in women. Early-life abuse/maltreatment and poverty/financial difficulties were associated with worse psychomotor speed.
