Associations of Domain-Specific Physical Activity With Leisure-Time Sedentary Behaviors in Chinese Professionals

Objective: To understand the association of domain-specific physical activity (PA) with leisure-time sedentary behavior (LTSB) among Chinese professionals. Methods: Totally, 3326 workers aged 35 to 64 years old from Beijing city and Zhejiang province were asked information on domain-specific PA with a revised Global Physical Activity Questionnaire (GPAQ). The association of domain-specific PA with LTSB-lifestyle (>= 4 hours/day spent on LTSB) was examined with a binary logistic regression model. Results: Compared with sedentary occupational activity (OA), light-, moderate-, and vigorous-intensity OA were respectively associated with 55.3% (ORs, 0.447; 95%CI, 0.378 to 0.529), 63.5% (ORs, 0.365; 95%CI, 0.285 to 0.468), and 77.1% (ORs, 0.229; 95%CI, 0.126 to 0.417) less the odds of having LTSB-lifestyle. Those performing domestic activity (DA) are greater than and equal to 19.6 MET-hours/week had 30.1% (ORs, 0.699; 95% CI, 0.576 to 0.848) less the odds. Conclusions: Both non-sedentary occupations and DA were negatively associated with LTSB-lifestyle in these professionals.
