In the intervention group and the control group, one middle school and one high school were randomly selected. The students from the two classes randomly selected in the first and second grades in the four schools that were selected, the questionnaire survey and medical examination was conducted before and after the intervention to evaluate the intervention effect.

          Results After intervention, the ratio of overweight and obesity of the intervention group decreased from 22.70% before intervention to 17.45%, statistical significance (χ 2 = 4.11, P <0.05), and the ratio of overweight and obesity of the control group increased from 22.39% before intervention to 22.91%, no significant difference ( P>0.05). After the intervention, the response rates of limiting red meat, fried food and sugar-sweetened beverages were all higher than those before the intervention, the differences were statistically significant (χ 2 = 125.73, 10.69, 208.55, 170.66, 50.01, P<0.01).

          Conclusion The comprehensive intervention measures of overweight and obesity in the model of health promotion school can encourage students to develop healthy behaviors and effectively prevent and control middle school students from overweight and obesity, and it is easy to form a long-term intervention mechanism.
