摘要

Overweight and obesity in adult populations is considered to be a growing epidemic worldwide, and appears to be rapidly increasing in China. From 1992 to 2002, the incidence of overweight in adults increased by 39.0%, while that of obesity doubled. To identify the determinants of adult overweight and obesity in China, micro-level data from a questionnaire survey entitled the Preference Parameters Study,' which was conducted by the Global Centers of Excellence programme at Osaka University, were analysed. In addition to the entire sample, data from urban and rural subsamples were also analysed in order to investigate whether the determinants of overweight and obesity differed. The results suggested that body mass index (BMI) is correlated with subjective well-being, gender, age, labour intensity and drinking and eating habits among urban respondents, and with age, monthly income, number of siblings and eating habits among rural respondents.
