The multivariate logistic regression analysis suggested that boys ( OR=2.059, 95%CI：1.949-2.175), not living on campus( OR=1.306, 95%CI 1.214-1.405), history of alcohol consumption ( OR=1.158, 95%CI：1.083-1.238 ), average daily consumption of sugar-sweetened beverages in the past week ( less than once, OR=1.214, 95%CI 1.103-1.336; once and more, OR=1.431, 95%CI 1.259-1.626 ), average daily consumption of fries in the past week ( less than once, OR=1.171, 95%CI 1.065-1.288; once and more, OR=1.266, 95%CI 1.102-1.454 ), and average daily consumption of sweets in the past week (less than once, OR=0.727, 95%CI 0.658-0.802; once and more, OR=0.504, 95%CI 0.444-0.572) were associated with overweight and obesity in students. @*Conclusion @#The prevalence rates of overweight and obesity among students aged 7-22 years in Zhejiang Province are 13.99% and 8.75%, respectively, which are associated with boys, not living on campus, and consumption of sugar-sweetened beverages, fries, sweets and alcohol.
