Factors related to obesity and overweight in Chinese population. A: Factors related to obesity and overweight in total adult population (left), male adult population (middle) and female adult population (right) in China. B: Factors related to obesity and overweight in children and adolescents (left), boys (middle) and girls (right) in China. Multiple logistic regression models were used to estimate the association between obesity and overweight with all potentially associated variables for total and sex-specific populations. In the adult population, the models included geographical regions, urbanization, income quartiles, sex, age, marital status, education, employment, smoking, alcohol drinking and physical activity. Among children aged 0-5 the models included parental levels of education, employment, smoking, alcohol drinking, and physical activity as well as the family income quartiles, geographical regions, urbanization. The underweight population were not included in these models. Adjusted Odds ratios (ORs) and 95%CI from logistic regression were presented with the Forest plot.
