目的：研究抽样偏差对暴饮暴食障碍(Bed)黑人和白人妇女招募临床样本的影响。方法：对来自新英格兰妇女健康项目的35名黑人和302名白人连续接受评估的临床样本和来自新英格兰妇女健康项目的黑人和白人妇女的社区样本的临床特征进行比较。结果：在白人女性中，诊所和社区样本在某些特征上存在差异(较高的身体质量指数[BMI]，临床样本中对饮食和形状的担忧较多)，但这些差异反映了轻微到中等的影响大小。相比之下，在黑人女性中，与社区样本相比，临床样本在饮食失调的几个特征(饮食担忧、饮食约束和形状担忧)方面的水平显著更高(大效应量)，更高的BMI(中等效应量)，但暴饮暴食的频率(中等效应量)更低。对临床样本中黑人和白人女性的比较显示，除了黑人女性的BMI显著更高外，临床表现几乎没有差异。结论：白人和黑人招募的女性卧床临床样本之间似乎都存在抽样偏差，尽管黑人女性的偏差似乎要大得多。寻求治疗的黑人女性与不寻求治疗的黑人女性有着显著不同的特征。(C)2005年，由威利期刊公司出版。
Objective: The current study investigated sampling bias as it affects recruited clinic samples of Black and White women with binge eating disorder (BED).Methods: Clinical characteristics of a recruited clinic sample (35 Black and 302 White consecutively evaluated women) with BED were compared with a community sample of Black and White women with BED drawn from the New England Women's Health Project. The clinic and community groups met the same definition of BED and were assessed with identical methods.Results: Among White women, the clinic and community samples differed on some features (higher body mass index [BMI], and greater eating concerns and shape concerns in the clinic sample) but these differences reflected small to moderate effects sizes. In contrast, among Black women, the clinic sample had substantially higher levels (large effect sizes) of several features of eating disorders (eating concerns, dietary restraint, and shape concern), higher (moderate effect size) BMI, but lower frequency of binge eating (moderate effect size) than the community sample. A comparison of Black and White women within the clinic sample revealed little difference in clinical presentation, except for the significantly higher BMI among Black women.Conclusion: A sampling bias appears to exist between both white and Black recruited clinic samples of women with BED, although the bias appears to be substantially greater for Black women. Black women with BED who seek treatment have significantly different characteristics than those who do not. (c) 2005 by Wiley Periodicals, Inc.
