Association between household physical activity level and type 2 diabetes among urban males in northern China

Physical activity contributes to preventing type 2 diabetes (T2D). Doing housework is an unstructured mild-intensity physical activity. We aimed to investigate the association between household physical activity level (HPAL) and T2D in urban Chinese men. This is a cross-sectional study. This study contained 13,862 male adults aged 35–78 (48.4 ± 7.1) years. According to the self-reported time (hours/day [h/d]) spent on housework, they were stratified into three levels: 0 h/d, >0–2 h/d, and >2 h/d. The association of HPAL with T2D was investigated by logistic regression analysis. The odds ratios (ORs) for T2D across increasing categories of HPAL were 1.00 (reference), 0.80 (95% confidence interval [CI] 0.72–0.89), and 0.60 (95% CI 0.51–0.70), respectively (P for trend
