While overweight and obese children are more likely to have overweight or obese parents, less is known about the effect of parental weight status on children's success in weight management programmes.
This study was a secondary data analysis of a randomized controlled trial and investigated the impact of having zero, one or two obese parents on children's success in a school-based weight management programme.
Sixty-one Mexican-American children participated in a 24-week school-based weight management intervention which took place in 2005-2006. Children's heights and weights were measured at baseline, 3, 6 and 12 months. Parental weight status was assessed at baseline. Repeated measures anova and ancova were conducted to compare changes in children's weight within and between groups, respectively.
Within-group comparisons revealed that the intervention led to significant decreases in standardized body mass index (zBMI) for children with zero (F = 23.16, P < .001) or one obese (F = 4.99, P < .05) parent. Between-group comparisons indicated that children with zero and one obese parents demonstrated greater decreases in zBMI compared to children with two obese parents at every time point.
The school-based weight management programme appears to be most efficacious for children with one or no obese parents compared to children with two obese parents. These results demonstrate the need to consider parental weight status when engaging in childhood weight management efforts.
超重和肥胖儿童的父母更有可能超重或肥胖，但关于父母体重状况对儿童体重管理项目成效的影响，人们了解得较少。
本研究是一项对随机对照试验的二次数据分析，旨在调查有零个、一个或两个肥胖父母对儿童在校体重管理项目成效的影响。
61名墨西哥裔美国儿童参与了2005 - 2006年开展的一项为期24周的在校体重管理干预。在基线、3个月、6个月和12个月时测量儿童的身高和体重。在基线时评估父母的体重状况。分别进行重复测量方差分析和协方差分析，以比较组内和组间儿童体重的变化。
组内比较显示，对于父母均不肥胖（F = 23.16，P <.001）或父母一方肥胖（F = 4.99，P <.05）的儿童，干预导致标准化体重指数（zBMI）显著下降。组间比较表明，在每个时间点，父母均不肥胖和父母一方肥胖的儿童与父母双方均肥胖的儿童相比，zBMI下降幅度更大。
与父母双方均肥胖的儿童相比，在校体重管理项目对父母一方肥胖或父母均不肥胖的儿童似乎最有效。这些结果表明，在进行儿童体重管理工作时需要考虑父母的体重状况。
