This study examined the correlates of race, weight status, and binge eating among 715 female undergraduate students (77% Caucasian; 13% African American) enrolled at an urban university. Approximately 21.7% of Caucasians and 36.8% of African-Americans (AA) were overweight/obese. Higher BMI was associated with BED, and severity of binge eating symptoms. After removing participants who endorsed compensatory behaviors ≥ 1×/week from the analyses, 8.4% of the sample met criteria for BED (2.4% of the AA and 9.9% of the Caucasian students) and 44% reported severe binge eating symptoms. AA students were less likely to have BED than Caucasian students and reported less severe binge eating symptomatology. For Caucasian students, mood, cognitive restraint, drive for thinness, and BMI all contributed significant individual variance in binge eating severity. For African Americans, mood, body image dissatisfaction, and drive for thinness were found to be unique contributors. For those meeting criteria for BED, retrospectively recalled predictors of binge eating included negative affect (e.g., self-anger, worry, guilt), but not hunger. Behavioral triggers for binge behavior differed by race, as well, with African American students retrospectively reporting lower levels of anxiety prior to bingeing. Results from this study suggest that there are racial differences in binge eating behaviors. Future studies are needed to examine differences in eating practices among racial groups (e.g., grazing, large portions, high fat food preparation) that may contribute to early onset weight gain and obesity. The results suggest the importance of sensitive tailored weight and disordered eating interventions for college women from diverse backgrounds.
本研究调查了 715 名女大学生（77%为白种人，13%为非裔美国人）的种族、体重状况和暴食行为的相关性，这些学生就读于一所城市大学。大约 21.7%的白人和 36.8%的非裔美国人（AA）超重/肥胖。较高的 BMI 与 BED 和暴食症状的严重程度有关。在从分析中排除每周至少有一次代偿性行为的参与者后，8.4%的样本符合 BED 标准（2.4%的 AA 和 9.9%的白种人学生），44%报告严重的暴食症状。AA 学生患 BED 的可能性低于白种人学生，且暴食症状的严重程度较轻。对于白种人学生，情绪、认知约束、对瘦的渴望和 BMI 都对暴食严重程度有显著的个体差异。对于非裔美国人，情绪、身体形象不满和对瘦的渴望是独特的贡献因素。对于符合 BED 标准的人，暴食的回溯预测因素包括负性情绪（例如，自我愤怒、担忧、内疚），而不是饥饿。暴食行为的行为触发因素因种族而异，非裔美国学生在暴食前报告的焦虑水平较低。这项研究的结果表明，暴食行为存在种族差异。需要进一步的研究来检查不同种族群体的饮食行为差异（例如，频繁进食、大量进食、高脂肪食物准备），这些差异可能导致体重早期增加和肥胖。结果表明，对于来自不同背景的大学生，需要进行敏感和量身定制的体重和饮食失调干预。
