本研究引入浓度指数（CI）来评估美国18-60岁成年人肥胖分布的社会经济不平等。CI提供了社会经济不平等的总结性衡量标准，并实现了跨性别、年龄和种族的比较。数据来自1988-1994年国家健康和营养调查III （NHANES III）。肥胖的社会经济不平等程度在性别、年龄和种族群体中差异很大。在女性中，我们发现与男性相比，社会经济地位（SES）与肥胖之间存在更强的负相关，与其他年龄组相比，中年成年人（41-49岁）的社会经济不平等更大。与之前的研究一致，我们发现社会经济地位和肥胖之间的关系存在显著的种族差异。尽管现有文献记录了少数族裔中肥胖的患病率高于白人，但我们的研究结果显示，少数族裔中肥胖的社会经济不平等程度较低。我们的分析表明，性别、年龄和种族可能是肥胖中社会经济不平等的重要因素。(C) 2003 Elsevier Ltd.版权所有。
This study introduces the concentration index (CI) to assess socioeconomic inequality in the distribution of obesity among American adults aged 18-60 years old. The CI provides a summary measure of socioeconomic inequality, and enabled comparisons across gender, age, and ethnicity. Data from the National Health and Nutrition Examination Survey III, 1988-1994 (NHANES III) were used. The degree of socioeconomic inequality in obesity varied considerably across gender, age, and ethnic groups. Among women, we found a stronger, inverse association between socioeconomic status (SES) and obesity compared with men, as well as greater socioeconomic inequality among middle-aged adults (41-49) compared to other age groups. Consistent with previous studies, we found remarkable ethnic differences in the relationship between SES and obesity. Although the extant literature documented a higher prevalence of obesity among minorities than in whites, our results presented a lower socioeconomic inequality in obesity within minority groups. Our analyses suggested that gender, age, and ethnicity could be important factors on socioeconomic inequality in obesity. (C) 2003 Elsevier Ltd. All rights reserved.
