目的：描述 URMEL-ICE（一种基于德国学校的超重预防干预措施）对儿童 BMI 和其他脂肪量指标的影响。方法：采用整群随机对照设计。以体力活动、看电视时间和软饮料消费为重点的干预措施已纳入二年级课程，并由任课教师亲自实施。它包括 29 节教学课、每天 2 节短练习和 6 节家庭作业课。 BMI 被评估为主要结果指标，腰围和皮褶厚度作为次要结果。分析了 945 名儿童的数据。结果：根据基线值进行调整的多变量分析显示，干预措施对 BMI 没有显着影响，但对腰围（-0.85；95% 置信区间 (95% CI) -1.59 至 -0.12）和肩胛下皮褶厚度（-0.64；95% CI -1.25 至 -0.02）有显着影响。对基线和随访之间的个体时间滞后进行额外调整后，这些效应降低至-0.60（95% CI -1.25至0.05）和-0.61（95% CI -1.26至0.04），并失去统计学意义。结论：这项研究有助于超重预防的随机学校研究领域，并表明在一年内，综合干预对 BMI 没有影响，但可以实现对脂肪量产生影响的趋势。版权所有 (C) 2012 S.

Objective: To describe the effects of URMEL-ICE, a German school-based intervention for overweight prevention, on children's BMI and other measures of fat mass. Methods: A cluster-randomised controlled design was used. The intervention which focused on physical activity, TV time and soft drink consumption was integrated into a second-grade curriculum and was implemented by classroom teachers themselves. It comprised 29 teaching lessons, 2 short exercise blocks per day and 6 family homework lessons. BMI was assessed as primary outcome measure, waist circumference and skinfold thickness as secondary outcomes. Data of 945 children were analysed. Results: Multivariate analyses adjusted for baseline values showed no statistically significant effect of the intervention on BMI, but on waist circumference (-0.85; 95% confidence interval (95% CI) -1.59 to -0.12) and subscapular skinfold thickness (-0.64; 95% CI -1.25 to -0.02). After additional adjustment for individual time lag between baseline and follow-up, these effects were reduced to -0.60 (95% CI -1.25 to 0.05) and -0.61 (95% CI -1.26 to 0.04) and lost their statistical significance. Conclusion: This study contributes to the field of randomised school-based studies on overweight prevention and shows that within a 1-year, integrated intervention no effect on BMI, but a tendency towards effects on fat mass can be achieved.
