Abstract
OBJECTIVES: 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. STUDY DESIGN: This is a cross-sectional study. METHODS: 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. RESULTS: 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 <0.001), after adjusting for confounding factors. Further adjustment for waist circumference or body mass index (BMI) had a minimal impact on these ORs. The inverse association of HPAL with T2D was persistent in subgroup analyses based on age, hypertension, family history of diabetes, smoking, BMI, waist circumstance, and fasting plasma glucose level. CONCLUSION: Our findings indicated that HPAL was inversely associated with the risk of T2D among urban males in northern China. This implied that household physical activity may contribute to long-term glucose control. Well-designed longitudinal studies are required to improve our understanding of this association.
