An interesting debate in the literature is about the role of race/ethnicity not only as a risk factor for eating disorders (EDs), but also as a moderator of the relations between other risk factors and ED symptoms. The following research question was explored: Does race/ethnicity moderate the relations between the implicit belief that high-fat food is shameful and ED symptoms?
About 15,000 (N = 14,964) volunteers (67.7% White, 7.7% Asian, 7.4% Hispanic, 6.9% Black) completed the Implicit Association Test (IAT) measuring the implicit associations between high-fat (vs. low-fat) food and shameful (vs. acceptable) on the Project Implicit mental-health website (https://implicit.harvard.edu) between 2011 and 2017. ED symptoms and demographics were measured via self-report.
Race/ethnicity moderated (beta = 0.087, p = .002) the relations between IAT and ED symptoms, adjusting for BMI, age, sex, education, such that the IAT was related to ED symptoms among Whites (r = 0.113, p < .001), Hispanics (r = 0.086, p = .004), and Asians (r = 0.097, p = .001), but not Blacks (r = 0.056, p = .071).
Although the effect size was small, findings imply that some ED risk factors may vary among racial/ethnic groups. Future studies should use prospective designs to examine whether implicit biases actually represent a risk factor for ED symptoms and whether this varies by race/ethnicity.
文献中存在一个有趣的争论，即种族/民族不仅是饮食失调（ED）的风险因素，而且还是其他风险因素与 ED 症状之间关系的调节因素。本研究探讨了以下问题：种族/民族是否调节了对高脂肪食物感到羞耻的内隐信念与 ED 症状之间的关系？
约 15000 名（N=14964）志愿者（67.7%为白人，7.7%为亚裔，7.4%为西班牙裔，6.9%为黑人）于 2011 年至 2017 年在 Project Implicit 心理健康网站（https://implicit.harvard.edu）上完成了内隐联想测验（IAT），该测验测量了高脂肪（与低脂肪）食物与羞耻（与可接受）之间的内隐联想。ED 症状和人口统计学数据通过自我报告进行测量。
种族/民族调节了（β=0.087，p=0.002）IAT 与 ED 症状之间的关系，调整了 BMI、年龄、性别、教育等因素，使得 IAT 与白人（r=0.113，p<0.001）、西班牙裔（r=0.086，p=0.004）和亚裔（r=0.097，p=0.001）的 ED 症状相关，但与黑人（r=0.056，p=0.071）无关。
尽管效应大小较小，但研究结果表明，一些 ED 风险因素可能因种族/民族群体而异。未来的研究应采用前瞻性设计，以检验内隐偏见是否确实是 ED 症状的风险因素，以及这种情况是否因种族/民族而异。
