Loneliness is a salient risk factor for obesity, emotional eating, and poor diet. Because adolescents and parents are embedded within a family unit, their experiences of loneliness may be associated with both their own and one another's behaviors. To examine the extent to which parent and child loneliness predict body mass index (BMI) and eating in parents and adolescents, an actor–partner interdependence model of loneliness, eating, and BMI in adolescent–parent dyads was analyzed. There were actor effects among adolescents such that greater loneliness was positively associated with emotional eating and BMI‐z, and there was an actor effect among parents such that higher loneliness was positively related to emotional eating. There was a partner effect among adolescents such that greater parental loneliness was positively associated with adolescent emotional eating, and there was a partner effect among parents such that higher adolescent loneliness was positively associated with parental emotional eating. There were several actor–partner effects for loneliness and junk food in dyads with boys. Findings highlight the importance of dyadic models of loneliness in adolescent–parent dyads.

来自家庭生活，活动，阳光，健康和饮食研究的父母-青少年双性恋的孤独，进食和体重指数

孤独是肥胖，情绪饮食和不良饮食的重要危险因素。由于青少年和父母都嵌入一个家庭单元中，因此他们的孤独感可能与他们自己和彼此的行为有关。为了检查父母和孩子的孤独感在多大程度上预测了父母和青少年的体重指数（BMI）和进食，我们分析了青少年-父母双子座的行为者-伴侣相互依赖性的孤独，进食和BMI模型。有青少年演员的影响，使得更多的孤独感呈正情绪饮食和BMI-相关ž，并且父母之间有演员效应，因此较高的孤独感与情绪饮食成正相关。青少年之间有伴侣效应，父母的孤独感与青少年的情感饮食呈正相关，而父母之间的伴侣效应则是青少年的孤独感与父母的情感饮食呈正相关。在男生双子座中，孤独感和垃圾食品对演员和伴侣有多种影响。研究结果突显了二元模型的孤独感在青少年父母双胞胎中的重要性。
