Adolescent disordered eating and obesity are interrelated and adversely relate to mental and metabolic health. Parental feeding practices have been associated with adolescent disordered eating and obesity. Yet, observable interactions related to food parenting have not been well characterized. To address this gap, N = 30 adolescents (M ± SD 14 ± 2 year) at risk for adult obesity due to above-average body mass index (BMI ≥70th percentile) or parental obesity (BMI ≥30 kg/m2 ) participated in a video-recorded parent-adolescent task to discuss a food/eating-related disagreement. Interactions were coded for individual/dyadic affect/content using the Interactional Dimensions Coding System. We examined associations of interaction qualities with parent-reported food practices, adolescent disordered eating behaviors/attitudes, and insulin resistance. Reported parenting practices were correlated with multiple interaction qualities (p-values <0.05), with the most consistent correspondence between parent-reported pressure to eat (e.g., pressure to eat more healthy foods) and negative aspects of parent-adolescent interactions. Also, after accounting for adolescent age, sex, and BMI-standard score, parent-adolescent interaction qualities were associated with adolescents' disordered eating and insulin resistance. Specifically, greater adolescent problem-solving related to less adolescent global disordered eating, shape, and weight concern (p-values <0.05); adolescent autonomy related to less weight concern (p = 0.03). Better parent communication skills were associated with less adolescent eating concern (p = 0.04), and observed dyadic mutuality related to adolescents' lower insulin resistance (p = 0.03). Parent-adolescent interaction qualities during food/eating-related disagreements show associations with parent-reported food practices and adolescent disordered eating. This method may offer a tool for measuring the qualities of parent-adolescent food/eating-related interactions. A nuanced understanding of conversations about food/eating may inform family-based intervention in youth at-risk for adult obesity.
青少年饮食失调和肥胖是相互关联的，与心理和代谢健康有负相关的关系。父母抚养孩子过程中给与的饮食与青少年饮食失调和肥胖有关。然而，与食物养育相关的可观察到的相互作用尚未得到很好的描述。为了填补这个空白，N=30名因身体质量指数(BMI≥70百分位)或父母肥胖(BMI≥30kg/m2)而有成人肥胖风险的青少年(M±SD 14±2y)参加了一项录像亲子任务，讨论与食物/饮食有关的分歧。使用交互维度编码系统对个体/二元情感/内容进行交互编码。我们检查了互动质量与父母报告的饮食习惯、青少年紊乱的饮食行为/态度和胰岛素抵抗的关系。报告的育儿行为与多种互动质量相关(p值<0.05)，父母报告的饮食压力(例如，吃更多健康食品的压力)与父母-青少年互动的消极方面之间的对应关系最为一致。此外，在考虑了青少年的年龄、性别和bmi标准评分后，父母与青少年的互动质量与青少年的饮食紊乱和胰岛素抵抗有关。具体来说，青少年解决问题的能力越强，青少年整体饮食失调、体型和体重担忧越少(p值<0.05); 青少年自主性与体重担忧较少相关(p = 0.03)。更好的父母沟通技巧与青少年较少的饮食关注相关(p = 0.04)，观察到的成对相互性与青少年较低的胰岛素抵抗相关(p = 0.03)。在与食物/饮食有关的分歧中，父母与青少年的互动质量与父母报告的饮食习惯和青少年饮食失调有关。这种方法可以提供一种工具来衡量父母和青少年与食物/饮食相关的互动的质量。对关于食物/饮食的对话的细致理解，可以为有成年肥胖风险的青少年提供以家庭为基础的干预。.
