Describe the three-year results of a program designed for the adoption of a healthy life style in primary school students on the body mass index (BMI) and the consumption of food.
Community randomized and controlled trial. Two communities in the State of Mexico with similar socio-demographic characteristics were randomized to implement the intervention (n=816) or serve as a control (n=408). The intervention was carried out in primary schools and it consisted of education on healthy habits, modification of distributed food and physical activity. The primary outcome was the change in BMI.
After three years, intervention resulted in a lower increase of BMI (1.6 vs. 1.9 Kg/m², p< 0.01) and a decreased consumption of total calories, bread, fat and sugar consumption in the schools.
School programs are useful to address childhood obesity, but its benefits are not immediate.
描述一项旨在让小学生采用健康生活方式的项目对体重指数（BMI）和食物消费的三年效果。
社区随机对照试验。墨西哥州两个具有相似社会人口特征的社区被随机分为实施干预组（n = 816）或对照组（n = 408）。干预在小学开展，包括健康习惯教育、分发食物的调整和体育活动。主要结局是BMI的变化。
三年后，干预导致BMI的增长较低（1.6 vs. 1.9 Kg/m²，p < 0.01），并且学校中总热量、面包、脂肪和糖的消费量减少。
学校项目有助于解决儿童肥胖问题，但其益处并非立竿见影。
