本研究探讨了早期青春期非洲裔美国女孩的身体质量指数（BMI）和随后的饮食失调（如节食和限制/清除）之间的身体不满的中介作用。参与者包括701名非洲裔美国女孩在第六和第七年级的城市学校服务于低收入社区，平均年龄12.15（SD=0.72）年。参与者在基线和大约6个月后进行评估。使用客观测量的身高和体重计算BMI z评分。参与者完成了关于体型不满和最近节食和限制/清除行为的问卷调查。在基线时，51.5%的参与者超重/肥胖，60.4%的人表示对身体不满意，希望变小。路径分析显示，身体不满意度的变化显著介导了初始BMI z评分与节食行为增加之间的关系（B =0.280，p=.001），但不影响限制/清除行为（p =.05）。身体的不满解释了早期青春期非洲裔美国女孩超重和随后的饮食失调症状之间的一些关联。通过筛查确定的身体不满意可能是进一步负面后果的指标，包括饮食失调行为。
This study examined the mediating role of body dissatisfaction between body mass index (BMI) and subsequent disordered eating (e.g. dieting and restricting/purging) among early adolescent African American girls. Participants included 701 African American girls in 6th and 7th grades in urban schools serving low-income communities, mean age 12.15 (SD=0.72) years. Participants were assessed at baseline and approximately 6 months later. Objectively measured height and weight were used to calculate BMI z-score. Participants completed questionnaires on body size dissatisfaction and recent dieting and restricting/purging behaviors. At baseline, 51.5% of participants were overweight/obese, and 60.4% expressed body dissatisfaction and a desire to be smaller. Path analytic analyses revealed change in body dissatisfaction significantly mediated the relation between initial BMI z-score and increases in dieting behaviors (B = 0.924, SE=0.280, p=.001) but not restricting/purging behaviors (p =.05). Body dissatisfaction explains some associations between excess body weight and subsequent disordered eating symptoms among early adolescent, African American girls. Body dissatisfaction, identified by screening, may be an indicator of further negative consequences, including disordered eating behaviors.
