To examine the association between physical activity and its different domains with sleep quality among rural older adults in Chengdu, and to further investigate whether this relationship differs between different age groups.
Using data from a cluster randomized controlled trial conducted from May 2021 to May 2023 in rural areas of Chengdu, the study included 511 older adults aged 60 years and above from eight villages. A questionnaire survey was conducted using the Physical Activity Scale for the Elderly (PASE), the Pittsburgh Sleep Quality Index (PSQI), and other instruments. Linear mixed models were used to analyze the relationship between physical activity andits three domains (leisure time physical activity, work-related physical activity, and household physical activity) and sleep quality.
There was a statistically significant association between leisure time physical activity and sleep quality (P< 0.05), and there was no statistically significant association of total physical activity, work-related physical activity, household physical activity with sleep quality (P > 0.05). The association between leisure time physical activity and sleep quality was more pronounced among those aged ≥ 70 years (β=-0.009, P=0.049).
Rural older adults with higher leisure time physical activity level have better sleep quality. There is a need to carry out intervention programs to increase leisure time physical activity level among rural older adults to improve their sleep quality.
