BACKGROUND: Evidence on the dose-response connection involving depressive symptoms and various types of physical activity in urban and rural populations is scarce. This study compares the dose-response connection across depressive symptoms and different types of activity in populations living in rural and urban areas. METHODS: The study is based on a cross-sectional weighted sample from the 2020 China Health and Retirement Longitudinal Study (CHARLS). Physical activity and depressive symptoms were assessed using self-reported activity from the CHARLS questionnaire and the Centre for Epidemiological Studies Depression Scale. Physical activity was computed in metabolic equivalents (METs) and depressive symptom cutoff is 10. 1 MET is the amount of oxygen used during rest (3.5 mL O2/kg/min). Multivariate logistic regression analyses were used to determine the dose-response relationship between different types of physical activity and depressive symptoms. RESULTS: Physical activity of different types showed a varying relationship with depressive symptoms with dose in rural populations. However, in urban populations, recreational physical activity exhibited a negative correlation with depressive symptoms, while non-recreational activity displayed a positive correlation. Specifically, in the rural population, 600-3,000 METs-min/week of recreational physical activity was inversely linked to depressive symptoms, but recreational physical activity exceeding 3,000 METs-min/week was asso...
