目的探讨儿童肥胖营养健康教育+运动综合干预的效果,并进行成本效益分析。方法 8所学校1507名小学生分为干预组(n=749)和对照组(n=758),干预措施为营养健康教育+运动的综合方法,干预1年后比较干预前后学生的肥胖相关形态学指标和血生化指标的变化,并进行干预成本效果和成本效益分析。结果干预后干预组男生肥胖检出率较干预前显著下降,干预组腰围、腰围身高比(WHR)、低密度脂蛋白水平显著低于对照组(均P<0.05),超重肥胖学生干预前的腰高比、低密度脂蛋白显著高于正常体重组学生(P<0.05),干预后无统计学差异。成本效益分析表明每下降1kg/m2(BMI)的成本为每人245.01元。结论营养健康教育和增加学生身体活动的综合干预方法可显著降低少年儿童肥胖的发生率,并获得收益。
Objective To explore the effects of obese children’s nutrition, health education and sports comprehensive intervention and carry out cost-benefit analysis. Methods A total of 1,507 pupils from 8 schools were divided into intervention group (n = 749) and control group (n = 758). The interventions were comprehensive nutrition and health education + exercise method. The obesity related morphology Indicators and changes in blood biochemical indicators, and intervention cost-effectiveness and cost-benefit analysis. Results After intervention, the prevalence of obesity in male intervention group was significantly lower than that before intervention. The WHR and LDL levels in intervention group were significantly lower than those in control group (all P <0.05) Waist-height ratio, low-density lipoprotein were significantly higher than those of normal weight group (P <0.05), and no significant difference after intervention. Cost-benefit analysis shows a cost of 245.01 yuan per person for every 1 kg / m2 (BMI) drop. Conclusion Nutritional health education and comprehensive intervention to increase physical activity of students can significantly reduce the incidence of obesity in children and obtain benefits.
