Investigation on physical activity and occupational stress among street office staffs of a city in China

Abstract

Objective: To investigate the relationship between physical activity (PA) and occupational stress(OS) among street office staffs of a city in china. Methods: A total of 504 street office staffs were collected by using stratified cluster sampling method from April to June in 2016, the international physical activity questionnaire(IPAQ) and job content questionnaire(JCQ) were used to survey the PA and OS. Results: In all subjects, the average score of job demand was(3.57±0.83), job decision was(2.71±0.63), social support was (2.79±0.79), demand-control ratio was (1.35±0.47) and 75.60% felt OS in self-evaluation. There were significant differences in OS between subjects with different gender, ages, job rank and job hours (P<0.01), also, there were significant differences in OS between different levels of occupational and leisure related PA (P<0.01). After controlling the potentially confounding effects, compared with low PA group, the OR values of medium-level and high-level groups of occupation-related PA were 1.38(95%CI=1.21~1.94) and 2.21(95%CI=2.06~2.67) respectively, however, the OR values of the medium-level and high-level groups of leisure-related PA were 0.89(95%CI=0.73~1.12) and 0.67(95%CI=0.38~0.96) respectively. Conclusion: Street office staffs have high level of OS, and leisure-related PA may be a protective factor for occupational stress.
