We sought to examine (1) the effects of ethnoracial status on Drive for Thinness (DT) and bulimic symptoms in a large sample of women, and (2) whether the strength of the association between DT and bulimic symptoms differed among ethnoracial groups.
Participants (M age = 19.59 years) from five ethnoracial groups (n = 14 American-Indian/Alaska Native, n = 233 Asian, n = 186 Black, n = 125 Hispanic White, and n = 990 non-Hispanic White), completed Eating Disorder Inventory (EDI; Garner et al., 1983) scales.
EDI DT scores were significantly lower in Black women compared to both Hispanic and non-Hispanic White women. EDI Bulimia scores were significantly lower in Black women compared to Asian, Hispanic, and non-Hispanic White women. No significant differences were observed among Asian, Hispanic, or non-Hispanic White women. Ethnoracial status moderated the association between DT and Bulimia scores, with a significantly weaker association in Black women compared to Asian, Hispanic, and non-Hispanic White women.
Findings refute misconceptions that disordered eating uniquely impacts White women and support a nuanced understanding of how ethnoracial status may influence eating disorder risk. Future work should examine sociocultural factors unique to ethnoracial subgroups to inform more targeted and effective intervention strategies.
我们试图研究（1）在一大群女性样本中，种族地位对瘦身驱动力（DT）和暴食症状的影响，以及（2）DT与暴食症状之间关联的强度在不同种族群体中是否存在差异。
来自五个种族群体的参与者（平均年龄 = 19.59岁）（n = 14名美国印第安人/阿拉斯加原住民，n = 233名亚洲人，n = 186名黑人，n = 125名西班牙裔白人，以及n = 990名非西班牙裔白人）完成了饮食失调量表（EDI；加纳等人，1983年）。
与西班牙裔和非西班牙裔白人女性相比，黑人女性的EDI DT得分显著更低。与亚洲、西班牙裔和非西班牙裔白人女性相比，黑人女性的EDI暴食得分显著更低。在亚洲、西班牙裔或非西班牙裔白人女性之间未观察到显著差异。种族地位调节了DT与暴食得分之间的关联，与亚洲、西班牙裔和非西班牙裔白人女性相比，黑人女性的关联显著更弱。
研究结果驳斥了饮食失调只对白人女性有独特影响的误解，并支持了对种族地位如何影响饮食失调风险的细致理解。未来的研究应考察不同种族亚群体特有的社会文化因素，以便制定更有针对性和有效的干预策略。
