The prevalence and influencing factors of physical activity and sedentary behaviour in the rural population in China: the Henan Rural Cohort Study

Abstract

ObjectivesTo estimate the prevalence and influencing factors of physical activity (PA) and sedentary behaviour (SB) in rural areas of China.DesignCross-sectional study.SettingA multistage, stratified cluster sampling method was used to obtain samples in the general population of Henan province in China.Participants38 515 participants aged 18–79 years were enrolled from the Henan Rural Cohort Study for the cross-sectional study.Main outcome measuresThe International Physical Activity Questionnaire was used to assess the levels of PA and SB. Multiple logistic regression analysis was used to calculate ORs and 95% CIs of potential influencing factors with physical inactivity.ResultsThe age-standardised prevalence of light PA and sitting >7.5 hours per day were 32.74% and 26.88% in the general Chinese rural adults, respectively. Gender differences were: 34.91%, 29.76% for men and 31.75%, 25.16% for women, respectively. The prevalence of participants with both light PA and sitting >7.5 hours per day was 13.95%. Education at least junior middle school, divorced/widowed/unmarried, RMB1000> per capita monthly income ≥RMB500, sitting >7.5 hours per day were negatively associated with light PA. For sitting >7.5 hours per day, the negative factors were being men, divorced/widowed/unmarried, heavy smoking, Fishery products, vegetable and fruits intake .ConclusionPhysical inactivity and SB were high in rural China. There is an increased need to promote a healthy lifestyle to the rural population.Clinical trial registrationThe Henan Rural Cohort Study has been registered with the Chinese Clinical Trial Register.Registration number: ChiCTR-OOC-15006699.http://www.chictr.org.cn/showproj.aspx?proj=11375

Independent and interactive effect of sitting time and physical activity on prevalence of hyperuricemia: the Henan Rural Cohort Study

“…The total value of MET was obtained by adding value of these three categories. Finally, based on the standard scoring criteria of IPAQ, three levels of PA were determined: the light (physically inactive) activity category was for individuals who met neither moderate activity nor vigorous activity criteria, moderate activity should meet either of the following four criteria: (1) [16]. The individual total ST every day in the past week was estimated by using the question "About how many hours in each 24-h day do you usually spend on sitting?…”

Independent and interactive effect of sitting time and physical activity on prevalence of hyperuricemia: the Henan Rural Cohort Study

“…PA and ST levels were assessed by using the International Physical Activity Questionnaire (IPAQ) [20]. As the details have been described previously [16,19], PA-metabolic equivalent (MET) was calculated by using MET coe cient of activity × duration (hour per time) × frequency (times per week) [19]. Therefore, according to the categories of PA, each category of vigorous activity, moderate activity and walking was calculated with the corresponding MET values of 8, 4, and 3.3 respectively.…”

“…The total value of MET was obtained by adding value of these three categories. Finally, based on the standard scoring criteria of IPAQ, three levels of PA were determined: light (physically inactive), moderate and vigorous [16]. The individual total ST every day in the past week was estimated by using the question "About how many hours in each 24-h day do you usually spend on sitting?…”

“…Whether PA can offset the adverse effect of ST still need to be elucidated. In addition, there are high prevalence of physical inactivity and sedentary behavior [16] as well as prevalent HUA in Chinese rural areas [17]. Given these, it is necessary to conduct this study to examine the independent association of PA and ST with serum uric acid level and HUA in rural Chinese population, and further to estimate the interaction effect of PA and ST on HUA.…”

The Influence of Social Support on Physical Activity in Chinese Adolescents: The Mediating Role of Exercise Self-Efficacy

“…Chinese adolescents were also found to be physically inactive, with only 10.3% performing moderate-to-vigorous PA for more than 60 min per day on five days a week, as recommended [6]. Furthermore, it has been shown that PA participation of Chinese adolescents varies by gender, with males more likely to be physically active than females [7][8][9]; in this case, gender is usually considered in the research to investigate correlates of PA.…”
