Ethnic disparities in childhood overweight are well-documented. In addition, disordered weight control behaviors (DWCB) have been linked to overweight and weight gain in multiple ways, but little is known about DWCB in youth of color, especially boys. We examined the distribution and determinants of ethnic and gender disparities in DWCB in early adolescents.
In fall 2005, 47 Massachusetts middle schools participating in the Healthy Choices overweight prevention study administered a self-report baseline survey assessing student sociodemographics, height, weight, and DWCB (vomiting or use of laxatives or diet pills in the past month to control weight). Data from 16,978 girls and boys were used in multivariate logistic regression models to estimate the odds of DWCB in youth of color compared with their white peers, controlling for individual- and school-level factors.
Among white youth, 2.7% of girls and 2.3% of boys reported DWCB. The odds of DWCB were elevated 2-10 times in most ethnic groups relative to whites. Disparities were attenuated but persisted after controlling for multiple individual- and school-level factors.
Ethnic disparities in DWCB must be considered in efforts to address the epidemic of childhood overweight.
儿童超重的种族差异已有大量记载。此外，不规律的体重控制行为（DWCB）与超重和体重增加存在多种关联，但关于有色人种青少年，尤其是男孩的 DWCB 知之甚少。我们研究了青少年 DWCB 的种族和性别差异的分布和决定因素。
2005 年秋季，参与健康选择超重预防研究的马萨诸塞州 47 所中学对学生的社会人口统计学、身高、体重和 DWCB（过去一个月为控制体重而呕吐或使用泻药或减肥药）进行了自我报告的基线调查。在多元逻辑回归模型中，使用来自 16978 名女孩和男孩的数据，控制个体和学校层面的因素，估计有色人种青少年与白人同龄人相比发生 DWCB 的几率。
在白人青少年中，2.7%的女孩和 2.3%的男孩报告有 DWCB。与白人相比，大多数族裔群体发生 DWCB 的几率高出 2 至 10 倍。在控制了多个个体和学校层面的因素后，差异虽然减弱但仍然存在。
在努力解决儿童超重的流行问题时，必须考虑 DWCB 的种族差异。
