Socio-demographic correlates of meeting the physical activity recommendation among Chinese adult internet users

Porpose: Physical inactivity is a modifiable risk factor for many chronic diseases. In China, inactive lifestyle is increasing yearly on Chinese adults by rapid economic development which produces their lifestyle changes. Thus, we investigated the prevalence and socio-demographic correlates of meeting the physical activity recommendation among Chinese adult internet users. Methods: Data were analyzed for 1394 Chinese adults who responded an internet based crosssectional survey. The International Physical Activity Questionnaire Chinese version was used to determine whether the individuals met the physical activity recommendation (150minutes/week) on the ACSM/AHA guideline. Demographic data (gender, age, marital status, employment status, educational level, annual income level, and body mass index) were also obtained. A multivariate logistic regression analysis was utilized. Results: Overall, 87.3% of respondents met the physical activity recommendation. Age and annual income were significantly associated with meeting the physical activity recommendation. Women aged 40-49 years were more likely to meet the physical activity recommendation than those aged 30-39 years (OR = 2.12). Women with annual incomes of 40000∼50000 Yuan were more likely to meet the physical activity recommendation than those with annual incomes of 30000 Yuan or less (OR = 2.40). Conclusion: The high prevalence rate and different socio-demographic correlates of meeting physical activity recommendation were observed among Chinese adults compared with these in developed countries. Specific strategies accounting for such socio-demographic correlates may be needed for effectively promoting physical activity among Chinese adults.
