研究背景情绪性进食过量（EOE）和情绪性进食不足（埃厄）是儿童早期常见的行为，被认为与体重状况有关。来自英国双胞胎队列的数据表明，环境，而不是遗传，目前研究的目的是在从另一个以人群为基础的英国双胞胎队列中选出的高或低肥胖风险的4岁双胞胎的子样本（n=398）中复制这一发现父母的评级的儿童EOE和埃厄进行了分析，使用遗传模型fitting.ResultsConclusionsGenetic的影响是不显着的，而共享的环境因素解释71%（52-79%）的方差EOE和77%（62-85%）在埃厄。两种行为呈正相关（r=0.53，95%CI：0.44，0.61），且影响情绪化进食和埃厄的共有环境因素中约有三分之二相同（r（C）=0.67，95%CI：0.51，0.85）。
BackgroundEmotional over-eating (EOE) and emotional under-eating (EUE) are common behaviours that develop in early childhood and are hypothesised to play a role in weight status. Data from a British twin cohort demonstrated that environmental, rather than genetic, factors shape individual differences in both behaviours in early childhood.ObjectiveMethodsThe aim of this current study was to replicate this finding in a subsample (n=398) of 4-year-old twins selected for high or low risk of obesity from another population-based cohort of British twins (the Twins Early Development Study).Parental ratings of child EOE and EUE were analysed using genetic model fitting.ResultsConclusionsGenetic influence was not significant, while shared environmental factors explained 71% (52-79%) of the variance in EOE and 77% (62-85%) in EUE. The two behaviours correlated positively (r=0.53, 95% CI: 0.44, 0.61), and about two-thirds of the shared environmental factors influencing EOE and EUE were the same (r(C)=0.67, 95% CI: 0.51, 0.85).Emotional eating in childhood is shaped by the home family environment; parents are therefore promising intervention targets.
