To understand the association of domain-specific physical activity (PA) with leisure-time sedentary behavior (LTSB) among Chinese professionals.
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.
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.
Both non-sedentary occupations and DA were negatively associated with LTSB-lifestyle in these professionals.
了解中国职业人群中特定领域身体活动（PA）与休闲久坐行为（LTSB）之间的关联。
采用修订后的全球身体活动问卷（GPAQ），对来自北京和浙江的3326名年龄在35至64岁的劳动者进行特定领域PA信息调查。使用二元逻辑回归模型检验特定领域PA与LTSB生活方式（每天LTSB时间≥4小时）之间的关联。
与久坐职业活动（OA）相比，轻度、中度和剧烈强度的OA分别使LTSB生活方式的几率降低55.3%（比值比[ORs]，0.447；95%置信区间[CI]，0.378至0.529）、63.5%（ORs，0.365；95%CI，0.285至0.468）和77.1%（ORs，0.229；95%CI，0.126至0.417）。每周进行家务活动（DA）≥19.6梅脱-小时的人群，其几率降低30.1%（ORs，0.699；95%CI，0.576至0.848）。
在这些职业人群中，非久坐职业和家务活动均与LTSB生活方式呈负相关。
