To assess whether parental overweight status and disinhibited overeating are predictive of daughters' accelerated weight gain and disinhibited overeating.
Participants were part of a longitudinal study of girls (N = 197) and their parents. Measured height and weight were used to calculate BMI [weight (kilograms)/height (meters)(2)]. Parents' disinhibited eating behavior was assessed using the Eating Inventory. Girls' disinhibited eating was assessed using a behavioral protocol to measure eating in the absence of hunger. Girls were classified based on parental overweight at study entry into four groups: neither, mother only, father only, or both parents overweight.
Girls with both parents overweight had the most rapid increases in BMI from 5 to 13 years of age; BMI increased most slowly among the neither parent overweight group, with intermediate increases in BMI among mother only and father only overweight groups. Daughters with both parents overweight at study entry were eight times more likely to be overweight at age 13, controlling for daughters' weight at age 5. Girls with both parents overweight had higher levels of disinhibited eating across all ages than all other groups. Although girls in all parental weight status groups showed increases in disinhibited eating over time, girls with both parents overweight had larger increases in disinhibited eating over time compared with all other groups.
Girls growing up in families differing in parental overweight had divergent developmental trajectories for BMI and disinhibited overeating. Findings reveal the need to focus prevention efforts on overweight parents of young children.
评估父母的超重状况和无节制的暴饮暴食是否可预测女儿体重的加速增加和无节制的暴饮暴食。
参与者是一项针对女孩（N = 197）及其父母的纵向研究的一部分。测量身高和体重用于计算体重指数[体重（千克）/身高（米）²]。使用饮食量表评估父母无节制的饮食行为。使用行为方案评估女孩无节制的饮食，以测量在不饥饿时的进食情况。根据研究开始时父母的超重情况将女孩分为四组：父母均不超重、仅母亲超重、仅父亲超重或父母均超重。
父母均超重的女孩在5至13岁期间体重指数增加最快；父母均不超重组的体重指数增加最慢，仅母亲超重组和仅父亲超重组的体重指数增加处于中间水平。在研究开始时父母均超重的女儿，在控制了女儿5岁时的体重后，13岁时超重的可能性是其他组的8倍。父母均超重的女孩在所有年龄段的无节制饮食水平均高于所有其他组。尽管所有父母体重状况组的女孩随着时间推移无节制饮食都有所增加，但与所有其他组相比，父母均超重的女孩随着时间推移无节制饮食增加幅度更大。
在父母超重情况不同的家庭中成长的女孩，在体重指数和无节制暴饮暴食方面有不同的发育轨迹。研究结果表明有必要将预防工作重点放在幼儿超重的父母身上。
