Active transport and health outcomes: Findings from a population study in jiangsu,China

To investigate the prevalence of active transport (at,defined as walking or bicycling for transport) and to explore the association between at and health outcomes,we conducted a population-based cross-sectional study in jiangsu,china,where walking and bicycling are still the main modes of transport. in this study,8400 community residents aged 18 or above were interviewed following a multistage random sampling method (100% response rate). face-to-face questionnaire survey data,anthropometric measurements,and biochemical data from blood tests were collected. results show that 49.6% of the subjects,as part of daily transport,actively traveled on average 5.3 days per week,53.5 minutes per day,and 300.3 minutes per week. there was an inverse correlation between at and some health outcomes: at respondents had a higher prevalence of cholesterol disorder; at respondents who actively travelled every day had a higher risk of diabetes,whilst at respondents with shorter daily or weekly duration had a lower risk of obesity,central obesity,and cholesterol disorder. moreover,at influences more health aspects among urban residents than among rural residents. findings of this study do not support the notion that at is beneficial to population health. further research is needed in determining the negative side effects of at. © 2013 shu-rong lu et al.
