This study aims to explore the prevalence and determinations of physical inactivity among hospital employees in Shanghai, China. A cross-sectional study of 4612 employees aged 19 to 68 years was conducted through stratified cluster sampling from different classes of Shanghai hospitals in 2011. The total physical activity was evaluated using the metabolic equivalent according to the Global Physical Activity Questionnaire. Among the participants, 38.5%, 32.3%, and 64.6% of the employees are inactive at work, commuting, and taking leisure time, respectively. Up to 41.8% of the men and 37.8% of the women (P = 0.012) are physically inactive. When the age and educational level are adjusted, male doctors and medical technicians show a higher percentage of physical inactivity than male workers in logistics (P = 0.001). Among females, employees who are working in second- and third-class hospitals show a higher proportion of physical inactivity than those who are working in community health care centers. Logistic regression analyses show that the odds ratios (ORs) of leisure-time physical inactivity associated with the intensity of physical activity at work are 2.259, 2.897, and 4.266 for men (P < 0.001) and 2.456, 3.259, and 3.587 for women (P < 0.001), respectively. The time during commuting activities is significantly associated with leisure-time physical inactivity in either sex (OR = 2.116 for men and 2.173 for women, P < 0.001). Hospital employees, particularly doctors and medical technicians, show a higher proportion of physical inactivity than other inhabitants in Shanghai. The time and intensity of activity at work and commuting are associated with leisure-time activities.
本研究旨在探讨中国上海医院员工中身体活动不足的患病率及其决定因素。2011年，通过对上海不同等级医院进行分层整群抽样，对4612名年龄在19至68岁的员工开展了一项横断面研究。根据全球身体活动问卷，使用代谢当量评估总体身体活动情况。在参与者中，分别有38.5%、32.3%和64.6%的员工在工作、通勤和休闲时间身体活动不足。高达41.8%的男性和37.8%的女性身体活动不足（P = 0.012）。在调整年龄和教育水平后，男性医生和医技人员身体活动不足的比例高于后勤男性职工（P = 0.001）。在女性中，在二级和三级医院工作的员工身体活动不足的比例高于在社区卫生服务中心工作的员工。逻辑回归分析表明，男性工作时身体活动强度与休闲时间身体活动不足的比值比（OR）分别为2.259、2.897和4.266（P < 0.001），女性分别为2.456、3.259和3.587（P < 0.001）。通勤活动时间与两性的休闲时间身体活动不足均显著相关（男性OR = 2.116，女性OR = 2.173，P < 0.001）。医院员工，尤其是医生和医技人员，身体活动不足的比例高于上海其他居民。工作和通勤时的活动时间及强度与休闲时间活动相关。
