PurposeTo examine the bidirectional relationships between sleep quality and cognitive function in older Chinese, and further examine the sex differences in the relationships using the random intercept cross-lagged panel model.DesignA secondary observational analysis of a physical activity clustered randomized controlled trial (The Stay Active While Aging).SettingEight villages in Sichuan, China.

Methods: This study was a secondary analysis of a cluster randomized controlled trial in China. Eight villages were randomized 1:1 to intervention or control group.
Introduction: How education affects the relationship between sedentary behavior and cognitive function remains unclear. The aim of this study was to investigate the relationship between mentally active sedentary behavior and cognitive function in rural older Chinese across different levels of education.
Methods: Data from 517 participants aged 60 years and older in rural China at baseline, 4 weeks, 8 weeks, 6 months, 12 months, and 24 months were analyzed.
On the basis of the atomic graph-theoretical index - aEAID (atomic Extended Adjacency matrix IDentification) and molecular adjacent topological index - ATID (Adjacent Topological IDentification) suggested by one of the authors (Zhang Q), a highly selective atomic topological index - aATID (atomic Adjacent Topological IDentification) index was suggested to identify the equivalent atoms in this study. The aATID index of an atom was derived from the number of the attached hydrogen atoms of the atom but omitting bond types. In this case, the suggested index can be used to identify equivalent atoms in chemistry but perhaps not equivalent in the molecular graph.

Objective: To evaluate the effects of a multilevel intervention for increasing leisure-time activity levels in Chinese older adults.
Design, Setting, And Participants: This cluster randomized trial was conducted from May 2021 to May 2023, including an 8-week intervention period and a follow-up period of 24 months.
