目的：本研究的目的是评估一项以学校为基础的为期2年的多因素干预对比利时弗兰德斯的BMI、饮食和体育活动行为的影响，目标是高社会经济地位和低社会经济地位（SES）社区的3-6岁儿童。设计：随机对照试验。三个不同干预社区的31所学前班和小学以及三个配对学校受试者：计算1102名儿童基线和随访时的BMI Z评分。从694这1102 childrens.Results的社会人口学数据和FFQ问卷：没有显着的影响，发现对BMI Z分数的总样本。然而，与低SES对照社区相比，低SES干预社区的BMI Z评分显著降低0.11，低SES对照社区的BMI Z评分增加0.04（F = 6.26，P = 0.01）。饮食行为、身体活动或屏幕时间没有发现显著的干预效果。有没有显着的年龄和性别的儿童对outcome variables.Conclusions的相互作用效应：虽然没有显着的影响，发现在总样本中的BMI Z-分数，这种干预措施有一个很好的效果，在低SES社区的幼儿体重增加过多减少。
Objective: The purpose of the present study was to evaluate the effects of a school-based, 2-year, multi-component intervention on BMI, eating and physical activity behaviour in Flanders, Belgium, targeting children aged 3-6 years in communities of high and low socio-economic status (SES).Design: Cluster-randomized controlled trial.Setting: Thirty-one pre-primary and primary schools in three different intervention communities and three paired-matched (on SES profile) control communities in Flanders, Belgium.Subjects: BMI Z-scores at baseline and follow-up were calculated for 1102 children. Questionnaires with sociodemographic data and FFQ were available from 694 of these 1102 children.Results: No significant effects were found on BMI Z-scores for the total sample. However, there was a significant decrease in BMI Z-score of 0.11 in the low-SES intervention community compared with the low-SES control community, where the BMI Z-score increased by 0.04 (F = 6.26, P = 0.01). No significant intervention effects could be found for eating behaviour, physical activity or screen-time. There were no significant interaction effects of age and gender of the children on the outcome variables.Conclusions: Although no significant effects were found for BMI Z-scores in the total sample, this intervention had a promising effect in the low-SES community of reducing excess weight gain among young children.
