Different family interactions related to body weight and shape may co-occur and represent a broader ‘family body culture’. This may be important in the context of COVID-19 due to a heightened focus on body weight/shape, and many young adults living back with their families. This study aimed to, first, explore relationships between different family body-related interactions to assess the presence of a family body culture, and second, explore relationships between aspects of family body culture, disordered eating and mental health among young adult females during the COVID-19 pandemic. Participants were 233 females aged 18–25 years who completed measures of family body culture (family fat talk; family weight concern; family weight teasing), disordered eating, anxiety and depression. Results showed all aspects of family body culture were significantly, positively related. Engaging in fat talk with family members (self fat talk) was a key correlate of disordered eating, anxiety and depression. Family concern with weight was also significantly associated with disordered eating. Findings suggest that among some families there is a more problematic family body culture with a greater importance placed on body weight and shape through various body-related interactions. Additionally, findings highlight two key aspects of family body culture related to disordered eating and wellbeing among young adult females. Specifically, vocalising critical remarks about one's own body when with family and an environment that may indirectly communicate a high importance of body weight and shape (e.g., via dieting). These should be considered in future family interventions to support healthy eating behaviours.

与体重和体形相关的不同家庭互动可能同时发生，并代表更广泛的“家庭身体文化”。这在 COVID-19 的背景下可能很重要，因为人们更加关注体重/体形，而且许多年轻人与家人住在一起。本研究旨在首先探讨不同家庭身体相关互动之间的关系，以评估家庭身体文化的存在；其次，探讨新冠疫情期间年轻成年女性家庭身体文化、饮食失调和心理健康之间的关系-19大流行。参与者是 233 名 18-25 岁的女性，她们完成了家庭身体文化（家庭肥胖谈话；家庭体重关注；家庭体重戏弄）、饮食失调、焦虑和抑郁的测量。结果显示家庭身体文化的各个方面都显着正相关。与家人进行肥胖谈话（自我肥胖谈话）是饮食失调、焦虑和抑郁的关键相关因素。家庭对体重的担忧也与饮食失调显着相关。研究结果表明，在一些家庭中，存在着更成问题的家庭身体文化，通过各种与身体相关的互动，更加重视体重和体形。此外，研究结果强调了家庭身体文化中与年轻成年女性饮食失调和健康相关的两个关键方面。具体来说，当与家人和环境在一起时，对自己的身体发出批评性的评论，这可能会间接传达体重和体形的高度重要性（例如，通过节食）。在未来的家庭干预中应考虑这些因素，以支持健康的饮食行为。
