Abstract

BACKGROUND

Childhood obesity is becoming a serious problem, and prevention programs are needed.

OBJECTIVE

The purpose of this study was to evaluate, after 1 y, the effectiveness of a multicomponent, school-based obesity intervention program.

METHODS

This intervention, conducted in Barcelona, Spain, was a quasi-experimental obesity primary prevention intervention targeting schoolchildren aged 9-10 y. Participants were assigned to an intervention group (IG) (1464 students) or to a comparison group (CG) (1609 students). The intervention consisted of a 9-session classroom program, 6 weekly sessions of physical education and out-of-school physical activity, and a workshop for families. It lasted from October 2011 to May 2012. Data obtained at baseline (spring 2011) and follow-up (spring 2012) included information on nutrition and physical activity, through 2 self-reported questionnaires, and measurement of weight, height, triceps skinfold thickness, and waist circumference. The cumulative incidence rate (CIR) of obesity was calculated from triceps skinfold measures. A multilevel logistic regression model was fitted to determine the association between the intervention and the CIR of obesity. The effect size of the program was estimated with Cohen's criteria.

RESULTS

The overall prevalence of obesity at baseline was 12.7%. At the 12-mo follow-up, the incidence of obesity was 7.8% in the IG compared with 11.4% in the CG (P < 0.005), representing 31% fewer new cases of obesity in the IG. The Cohen's d effect size of the program was 0.33. In the multilevel analysis, there was a protective effect of the intervention on the CIR of obesity at 12 mo (OR: 0.7; 95% CI: 0.5, 0.9) (P = 0.009).

CONCLUSIONS

The first Prevención de la Obesidad Infantil en Barcelona (Childhood Obesity Prevention in Barcelona) (POIBA) intervention, targeting children aged 9-10 y, reduced the incidence of obesity as measured by adiposity. The intervention could prevent 1 in 3 new cases of childhood obesity in this age range.

摘要

背景

儿童肥胖正成为一个严重的问题，因此需要预防项目。

目的

本研究旨在评估一项多组分、以学校为基础的肥胖干预项目在 1 年后的有效性。

方法

该干预措施在西班牙巴塞罗那进行，是一项针对 9-10 岁学龄儿童的肥胖初级预防干预的准实验。参与者被分配到干预组（IG）（1464 名学生）或对照组（CG）（1609 名学生）。干预措施包括 9 节课堂课程、6 节每周体能教育和课外体能活动以及家庭工作坊。它从 2011 年 10 月持续到 2012 年 5 月。在基线（2011 年春季）和随访（2012 年春季）中获得的数据包括通过 2 份自我报告问卷获得的营养和身体活动信息，以及体重、身高、三头肌皮褶厚度和腰围的测量值。肥胖的累积发病率（CIR）是从三头肌皮褶测量值计算得出的。使用多水平逻辑回归模型来确定干预与肥胖 CIR 之间的关联。使用 Cohen 标准估计该计划的效果大小。

结果

基线时肥胖的总体患病率为 12.7%。在 12 个月的随访中，IG 的肥胖发病率为 7.8%，CG 为 11.4%（P<0.005），IG 中肥胖的新发病例减少了 31%。该计划的 Cohen's d 效果大小为 0.33。在多层次分析中，干预措施对 12 个月时肥胖 CIR 具有保护作用（OR：0.7；95%CI：0.5，0.9）（P=0.009）。
