Effects of physical activity, sedentary time, and sleep duration on hypertension prevalence in Chongqing / 西安交通大学学报(医学版)

ABSTRACT

Objective: To explore the effects of physical activity, sedentary time, and sleep duration on the prevalence of hypertension in Chongqing municipality through the cross-sectional study. Methods: A multi-stage stratified random sampling method was adopted to conduct the questionnaire survey and physical examination on permanent residents (age>15 years old) from 4 rural and 4 urban areas in Chongqing. Data on basic personal information were collected and analyzed. Binary logistic regression was used to find potential risk factors for hypertension. Results: A total of 15,280 subjects were enrolled in this study. According to the Chinese Hypertension Prevention Guideline 2010, the prevalence of hypertension in the whole population was 20.7%. The result of binary Logistic regression analysis demonstrated that MET ≤2.29 h/d, sedentary time≤6.1 h/d, and sleeping duration≤ 6 h/d or >9 h/d were the risk factors for hypertension while sedentary time between 4.1-6.0 h/d was the protective factor of hypertension in Chongqing. For high risk factor (MET≤2.29 h/d, sedentary time≥6.1 h/d, and sleep duration≤6 h/d), the percentage in the rural residents was higher than that in the urban residents. For protective factor (sedentary time 4.1~6.0 h/d), the percentage in the rural residents was significantly lower than that in the urban residents. Conclusion: The prevalence of hypertension is high in Chongqing. Insufficient physical activity, long sedentary time, and insufficient/excessive sleep duration may increase the risk of hypertension. The higher prevalence of hypertension in rural areas may be correlated with insufficient physical activity, longer sedentary time, and insufficient/excessive sleep duration.
