背景：家庭环境会影响青少年肥胖的风险。然而，我们并不完全了解父母影响超重/肥胖青少年饮食行为的机制，特别是养育方式（例如，规则或惯例）和/或他们自己的饮食行为是否与其超重/肥胖青少年的饮食质量相关。 目的：本研究探讨了养育方式和/或父母饮食质量模型是否与超重/肥胖青少年的饮食质量相关，同时考虑养育方式和家庭功能的调节作用。方法：基线对 172 名参加生活方式改变干预措施的超重/肥胖青少年及其父母之一的数据进行了分析 [平均年龄 = 13.1 (1.8)；平均 BMI z 分数 = 2.70 (0.83)]。父母与青少年二人在网上完成了三项 24 小时饮食回忆。膳食质量指数是通过对 3 天的膳食回忆中评估的不同食物类别的分数进行求和来计算的。父母填写了有关家庭功能、饮食养育方式（即孩子是否每天吃早餐）和风格（权威和宽容）的调查问卷。使用 Stata 软件版本 13，通过路径分析对变量之间的相互关系进行建模。结果：饮食质量的父母模型与青少年饮食质量显着相关。此外，养育方式显着调节了父母的榜样作用，因此，权威的养育方式与塑造健康的饮食习惯相结合，与更好的青少年饮食质量相关。结论：这项工作表明，父母的健康行为榜样很重要；然而，有必要考虑建模所表达的更广泛的情感/关系背景，因为养育方式会调节这些影响。这项研究深入了解了养育方式如何改变父母建模的有效性，并强调需要考虑养育方式以提高当前基于家庭的干预措施的有效性。
Background: The familial environment can influence adolescents' risk for obesity. However, we do not fully understand the mechanisms through which parents can influence overweight/obese adolescents' dietary behaviours, specifically whether parenting practices (e.g., rules or routines) and/or their own dietary behaviours are associated with their overweight/obese adolescent's dietary quality.Objectives: This study examined whether parenting practices and/or parental modeling of dietary quality are associated with overweight/obese adolescents' dietary quality while considering the moderating effects of parenting styles and family functioning.Methods: Baseline data from 172 overweight/obese adolescents and one of their parents who enrolled in a lifestyle modification intervention were analyzed [mean age = 13.1 (1.8); mean BMI z-score = 2.70 (0.83)]. Parent-adolescent dyads completed three 24-hr dietary recalls online. An index of dietary quality was computed by summing the scores for different food categories assessed in the dietary recall over 3 days. Parents completed questionnaires about their family functioning, dietary parenting practices (i.e., whether child eats breakfast everyday), and styles (authoritative and permissive). Path analysis was used to model interrelationships among the variables using the Stata software version 13.Results: Parental modeling of dietary quality was significantly associated with adolescent dietary quality. Additionally, parenting styles significantly moderated parental modeling, such that an authoritative parenting style in conjunction with modeling healthy eating habits was associated with better adolescent dietary quality.Conclusions: This work suggests that parental modeling of health behaviours is important; however, it is necessary to consider the broader emotional/relational context into which modeling is expressed since parenting styles moderated these effects. This study provides insight into how parenting styles may alter the effectiveness of parental modeling and highlights the need to account for parenting styles to improve the efficacy of current family-based interventions.
