The current study examined predictors of eating and body image disturbances in psychiatrically hospitalized female adolescents and investigated whether the predictors differ by ethnicity.
Participants were 427 (320 Caucasian, 53 Latina, 54 African American) female adolescent psychiatric inpatients. Predictors of eating disorder features (dietary restraint, binge eating, and purging) and body image dissatisfaction (BID) were tested separately for the three ethnic groups. In addition to the eating and BID variables, the following predictor variables were considered: depression, anxiety, impulsivity, negative self-esteem, peer insecurity, and abuse.
Caucasians reported significantly higher levels of dietary restraint and BID than Latinas and African Americans, whereas reports of binge eating did not differ by ethnicity. Regression analyses revealed that the predictor variables accounted for significant and substantial amounts of the variance in the four eating and body image domains. Different psychological and social variables predicted eating disorder symptoms and BID across ethnic groups.
These findings suggest, for psychiatrically hospitalized adolescent females, that different patterns of factors may contribute to the maintenance of eating and body image disturbances across ethnic groups. Future research testing models of the etiology or maintenance of these disturbances needs to include ethnicity to ascertain whether the hypothesized components operate differently by ethnicity.
本研究调查了因精神疾病住院的女性青少年饮食及身体意象障碍的预测因素,并探究这些预测因素是否因种族不同而存在差异。
研究对象为427名因精神疾病住院的女性青少年(320名白人、53名拉丁裔、54名非裔美国人)。分别对三个种族的饮食失调特征(饮食节制、暴饮暴食和清除行为)及身体意象不满(BID)的预测因素进行了测试。除饮食及身体意象不满变量外,还考虑了以下预测变量:抑郁、焦虑、冲动性、消极自尊、同伴不安全感及虐待。
白人报告的饮食节制和身体意象不满水平显著高于拉丁裔和非裔美国人,而暴饮暴食的报告在种族间无差异。回归分析显示,预测变量在四个饮食及身体意象领域中解释了显著且大量的方差变异。不同的心理和社会变量在不同种族中预测饮食失调症状和身体意象不满。
这些发现表明,对于因精神疾病住院的青春期女性,不同模式的因素可能在不同种族中导致饮食及身体意象障碍的持续存在。未来关于这些障碍病因或持续存在模式的研究需要纳入种族因素,以确定假设的组成部分是否因种族不同而有不同作用。
