Objective To understand the associations of physical activity domains with metabolic syndrome among a middle-aged Chinese population. <br> Methods In all, 3326 professional adults aged 35-64 years from Beijing and Zhejiang province were recruited with a cluster random sampling method. The Global Physical Activity Questionnaire was modified, and the recommended Asia-Pacific cut-offs of waist circumstance were introduced into the criteria for metabolic syndrome from the Adult Treatment Panel III. A binary logistic regression model was applied to examine the association of all physical activity domains with the risk of the syndrome. <br> Results Participants who engaged in domestic activity for 31176 MET-min/week had a 41.6% less chance of having metabolic syndrome [odds ratio (OR), 0.584;95%confidence interval (CI), 0.480-0.710] than those without this activity. In adjusted models, adults who actively commuted for 333 MET-min/week but<528 MET-min/week had a 25%less chance of having the syndrome (OR, 0.750;95%CI, 0.582-0.966) than those who did not. No interaction was detected between the two domains of activity and the syndrome. <br> Conclusion This study highlighted the independently negative association of traffic and house activity with the prevalence of the syndrome in this sample with a generally low level of moderate activity.
