Prevalence and demographic correlates of meeting the recommendation among China’s Adult Physical Activity Guidelines / 体力科学

<p>Recently, the China Adult Physical Activity Guideline (CAPAG) have been published. However, it is unclear to know the prevalence of people meeting the CAPAG, and who meet. Therefore, we conducted this study to investigate the prevalence and demographic characteristics of people achieving the recommended CAPAG. Cross-sectional data in the present study was analyzed for 1,655 Chinese urban adults. The Chinese version of International Physical Activity Questionnaire was used to examine CAPAG level of adults. According to CAPAG, Chinese adults are recommend to meet ≥6000 Step/day. Demographic data, including age, marital status, educational level, income level, body mass index and self-rated health were obtained with the questionnaire. To examine the association of demographic and health status with PA level, a multivariate logistic regression analysis was utilized. Overall, 61.1% of respondents met the PA recommendation. Unmarried and healthy (self-rated health) were significantly associated with meeting the physical activity recommendation. Women aged 30 to 39 years were less likely to achieve the recommendation. Women with incomes of 1,000 Yuan or less were more likely to meet the recommendation than those with incomes of 4,000 Yuan or more. Adults with normal weight were more likely to those with underweight. Differences in associations of demographic correlates with the PA recommendation were observed between men and women, which suggest that gender-specific strategies might be more effective in promoting PA among Chinese urban adults.</p>

Age Differences in the Relation of Perceived Neighborhood Environment to Walking among Chinese adult women dwelling in urban area / 体力科学

Evidence from Western countries suggests that built environmental attributes can influence the physical activity participation in adults, but whether or not this is the case for Chinese is unknown. Also, the strength of the relationship of environment to physical activity may differ by age group. The present study examined age-related differences in associations between perceived neighborhood environment and walking in Chinese women dwelling in Beijing. Cross-sectional data were collected through an internet-based survey. Total of 737 women aged 30 to 59 years responded. All of them were then divided into three groups based on the age: aged from 30-39, from 40-49 and from 50-59. In addition to socio demographic information, the perceived neighborhood environment was measured by Neighborhood Environment Walkability Scale Questionnaire, and their walking time per week was collected through International Physical Activity Questionnaire. To measure relationship between perceived neighborhood environment and walking time, partial correlations were computed, adjusting for socio demographics. Walking time was significantly related to residential density in aged 40-49 years, and land use mix-access, walking/cycling facilities, traffic safety variables in aged 50-59 years. The present study indicates that there would be differences in associations between neighborhood attributes by age-groups. Future, public health promotion of walking activity and the design of interventions need to consider the contribution of neighborhood level built environment influences.

SOCIO-DEMOGRAPHIC CORRELATES OF MEETING THE PHYSICAL ACTIVITY RECOMMENDATION AMONG CHINESE ADULT INTERNET USERS / 体力科学

<b>Porpose:</b> 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.<b>Methods:</b> Data were analyzed for 1394 Chinese adults who responded an internet based cross-sectional 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.<b>Results:</b> 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).<b>Conclusion:</b> 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.
