The prevalence of weight-related problems in adolescents is high. Parents of adolescents may wonder whether talking about eating habits and weight is useful or detrimental.
To examine the associations between parent conversations about healthful eating and weight and adolescent disordered eating behaviors.
Cross-sectional analysis using data from 2 linked multilevel population-based studies.
Anthropometric assessments and surveys completed at school by adolescents and surveys completed at home by parents in 2009-2010.
Socioeconomically and racially/ethnically diverse sample (81% ethnic minority; 60% low income) of adolescents from Eating and Activity in Teens 2010 (EAT 2010) (n = 2793; mean age, 14.4 years) and parents from Project Families and Eating and Activity in Teens (Project F-EAT) (n = 3709; mean age, 42.3 years). EXPOSURE Parent conversations about healthful eating and weight/size.
Adolescent dieting, unhealthy weight-control behaviors, and binge eating.
Mothers and fathers who engaged in weight-related conversations had adolescents who were more likely to diet, use unhealthy weight-control behaviors, and engage in binge eating. Overweight or obese adolescents whose mothers engaged in conversations that were focused only on healthful eating behaviors were less likely to diet and use unhealthy weight-control behaviors. Additionally, subanalyses with adolescents with data from 2 parents showed that when both parents engaged in healthful eating conversations, their overweight or obese adolescent children were less likely to diet and use unhealthy weight-control behaviors.
Parent conversations focused on weight/size are associated with increased risk for adolescent disordered eating behaviors, whereas conversations focused on healthful eating are protective against disordered eating behaviors.
青少年体重相关问题的患病率很高。青少年的父母可能会想知道，谈论饮食习惯和体重是否有益或有害。
研究父母关于健康饮食和体重的谈话与青少年饮食失调行为之间的关系。
使用 2 项基于人群的多层次关联研究的数据进行横断面分析。
2009-2010 年，青少年在学校进行人体测量评估和调查，父母在家完成调查。
来自 Eating and Activity in Teens 2010（EAT 2010）（n=2793；平均年龄 14.4 岁）的社会经济和种族/民族多样化样本（少数民族占 81%；低收入者占 60%）和 Project Families and Eating and Activity in Teens（Project F-EAT）（n=3709；平均年龄 42.3 岁）的父母。
父母关于健康饮食和体重/大小的谈话。
青少年节食、不健康的体重控制行为和暴食。
参与与体重相关对话的母亲和父亲的孩子更有可能节食、使用不健康的体重控制行为和暴食。母亲进行仅关注健康饮食行为的对话的超重或肥胖青少年不太可能节食和使用不健康的体重控制行为。此外，对来自 2 位父母的青少年进行的亚分析表明，当父母双方都进行健康饮食对话时，他们超重或肥胖的青少年子女不太可能节食和使用不健康的体重控制行为。
关注体重/大小的父母谈话与青少年饮食失调行为的风险增加有关，而关注健康饮食的谈话则可预防饮食失调行为。
