流行病学研究表明，进食障碍症状的表现存在种族差异。然而，还没有研究检查种族和青春期饮食障碍症状轨迹之间的联系，这是为文化敏感的预防计划提供信息所必需的。目前这项研究的目的是检查从童年到成年的饮食障碍症状的轨迹，并检查种族是否与轨迹组成员有关。数据来自2,305名黑人和白人女孩，她们参与了一项基于社区的纵向队列研究(匹兹堡女孩研究)，调查精神病理学的发展。儿童版和成人版的饮食态度测试在9岁到21岁之间的六个时间点评估了自我报告的饮食失调症状。生长混合模型被用来检验节食、暴食症/食物专注和总进食障碍症状评分的发展轨迹。考虑到与种族和饮食失调的潜在混淆，经济压力(即接受公共援助)和体重被纳入协变量。在进食障碍症状中发现了四到六种不同的发展模式，包括没有、增加、减少或增加-减少的轨迹。黑人女孩更有可能处于节食、暴食症/食物专注和总进食障碍症状得分下降的轨道上。与黑人女孩相比，白人女孩更有可能遵循节食和总进食障碍症状得分增加的轨迹。这些结果强调了研究种族背景对进食障碍症状的影响的重要性，以及在这些群体中可能需要不同的预防干预措施的时间和重点。
Epidemiological research suggests racial differences in the presentation of eating disorder symptoms. However, no studies have examined associations between race and eating disorder symptom trajectories across youth and adolescence, which is necessary to inform culturally sensitive prevention programs. The purpose of the current study was to examine the trajectories of eating disorder symptoms from childhood to young adulthood and to examine whether race was associated with trajectory group membership. Data were drawn from 2,305 Black and White girls who participated in a community-based longitudinal cohort study (Pittsburgh Girls Study) examining the development of psychopathology. The child and adult versions of the Eating Attitudes Test assessed self-reported eating disorder symptoms at six time points between ages 9 and 21 years. Growth mixture modeling was used to examine developmental trajectories of dieting, bulimia/food preoccupation, and total eating disorder symptom scores. Given potential confounds with race and disordered eating, financial strain (i.e., receiving public assistance) and weight were included as covariates. Four to six distinct developmental patterns were found across eating disorder symptoms, including none, increasing, decreasing, or increasing-decreasing trajectories. Black girls had a greater likelihood of being in the decreasing trajectories for dieting, bulimia/food preoccupation, and total eating disorder symptom scores. White girls were more likely to follow increasing trajectories of dieting and total eating disorder symptom scores compared to Black girls. These results highlight the importance of examining the influence of racial background on eating disorder symptoms and the potential need for differences in the timing and focus of prevention interventions in these groups.
