目标。对652名学龄前儿童（72%的移民，38%的低教育水平（EL）父母）进行了多维生活方式干预，减少了体脂，但没有BMI和改善健康。本研究的目的是检验干预是否对移民和/或低EL父母的儿童同样有效。群集随机对照单盲试验，于2008/09年在瑞士随机选择的40所幼儿园进行。这种针对不同文化的干预包括体育活动计划和营养、媒体使用和睡眠方面的课程。主要结局包括BMI和有氧适能。次要结果包括体脂、腰围和运动敏捷性。流动父母的孩子从干预中获得的好处与他们的同龄人相似（p为相互作用>= 0.09）。然而，低EL父母的孩子受益较少，尽管这些差异没有达到统计学意义（交互作用>= 0.06）。非移民、移民、中/高EL和低EL父母的儿童BMI的平均干预效应值分别为-0.10、-0.05、-0.11和-0.04 kg/m(2)，有氧适能的平均干预效应值分别为0.55、0.20、0.37和-0.05个阶段。这种干预在移民父母的学龄前儿童中同样有效，而低EL父母的儿童受益较少。(C) 2012爱思唯尔公司版权所有。
Objective. A multidimensional lifestyle intervention performed in 652 preschoolers (72% of migrant, 38% of low educational level (EL) parents) reduced body fat, but not BMI and improved fitness. The objective of this study is to examine whether the intervention was equally effective in children of migrant and/or low EL parents.Methods. Cluster-randomized controlled single blinded trial, conducted in 2008/09 in 40 randomly selected preschools in Switzerland. The culturally tailored intervention consisted of a physical activity program and lessons on nutrition, media use and sleep. Primary outcomes included BMI and aerobic fitness. Secondary outcomes included %body fat, waist circumference and motor agility.Results. Children of migrant parents benefitted similarly from the intervention compared to their counterparts (p for interaction >= 0.09). However, children of low EL parents benefitted less, although these differences did not reach statistical significance (p for interaction >= 0.06). Average intervention effect sizes for BMI were -0.10, -0.05, -0.11 and -0.04 kg/m(2) and for aerobic fitness were 0.55, 0.20, 0.37 and -0.05 stages for children of non-migrant, migrant, middle/high EL and low EL parents, respectively.Conclusions. This intervention was similarly effective among preschoolers of migrant parents compared to their counterparts, while children of low EL parents benefitted less. (C) 2012 Elsevier Inc.
