SES were indicated bu per capita family income and parental tertiary education. The time trends of the associations between SES and childhood overweight and underweight were analyzed by Logistic regression, and the correlation between SES and childhood BMI were estimated by Quantile regression. RESULTS: The prevalence of overweight and underweight have increased by 1.22 times and 0.39 times, respectively. Logistic regression results show that family income per capita changed from a protective factor for childhood overweight into a risk factor over almost two decades, while parental tertiary education increased the odds more prominent. For childhood underweight, the SES indicators show no statistically significant effect. Estimations from Quantile regression also show the same pattern with Logistic results.
