Accelerometer-Measured Physical Activity in Chinese Adults

Background Following adoption of a Western lifestyle, China is experiencing a decline in physical activity levels, which is projected to contribute to future increases in the burden of chronic diseases. Purpose This study aims to target public health interventions and identify personal characteristics associated with physical activity and sedentary behavior in urban Chinese adults. Methods In a sample of 576 men and women aged 40–74 years from Shanghai, multiple logistic regression was used to examine demographic, anthropometric, and lifestyle factors in relation to levels of physical activity and sedentary behavior assessed by Actigraph accelerometers. Results Participants spent 317 minutes/day in physical activity and 509 minutes/day sedentary. In multivariate models, people aged ≥60 years were significantly less likely than those aged Conclusions Physical activity promotion programs in urban China should target older people, obese individuals, and cigarette smokers, as these population subgroups exhibited low levels of physical activity.
