Body image is multidimensional and less is known about how the combination of positive and negative body image relates to eating behaviors. We used a person-centered approach to identify profiles of body image and explore the relationship between profile membership, sex, age, race, and current marital status, and eating behaviors in a community sample of adults. We recruited 288 adults 18 and older living in the United States using Prolific Academic. Participants completed an online survey assessing body appreciation, functionality appreciation, body dissatisfaction, weight bias internalization, and adaptive and maladaptive eating behaviors. We used latent profile analysis to identify four distinct body image profiles: appreciation & mild dissatisfaction, functional appreciation & moderate dissatisfaction, strong dissatisfaction, and strong appreciation. Profile membership differed by sex with more women and younger adults in profiles higher in negative body image. The relationships between profiles and eating behaviors differed; the three profiles including negative body image had the lowest adaptive and highest maladaptive eating behaviors. The identification of clinically relevant profiles: (1) confirm positive and negative body image coexist, (2) identify high- and low-risk profiles of body image and eating behavior, and (3) offer preliminary suggestions for screening and tailoring preventive interventions.
身体意象是多维的，对于积极和消极身体意象的组合如何与饮食行为相关知之甚少。我们采用以个体为中心的方法来确定身体意象的特征，并在一个成年人群体中探讨特征分类、性别、年龄、种族和当前婚姻状况与饮食行为之间的关系。我们使用 Prolific Academic 在美国招募了 288 名 18 岁及以上的成年人。参与者完成了一项在线调查，评估了身体欣赏、功能欣赏、身体不满、体重偏见内化以及适应性和非适应性饮食行为。我们使用潜在剖面分析来识别出四个不同的身体意象特征：欣赏和轻度不满、功能欣赏和中度不满、强烈不满和强烈欣赏。特征分类因性别而异，具有更高负面身体意象的特征分类中女性和年轻人更多。特征分类与饮食行为之间的关系也不同；包括负面身体意象的三个特征分类具有最低的适应性和最高的非适应性饮食行为。这些发现具有临床意义，确认了积极和消极的身体意象同时存在，确定了高风险和低风险的身体意象和饮食行为特征分类，并为筛查和定制预防干预措施提供了初步建议。
