利用国家收入动态研究的数据，我们记录了种族隔离后南非不同种族和性别之间体重不足和肥胖的差异。使用非线性分解方法，我们分解种族内跨性别的这些差异，然后分解性别内跨种族的差异。不同性别的肥胖和体重不足差异中，只有不到三分之一是由协变量的差异来解释的。相比之下，至少 70% 的不同种族肥胖差异可以通过协变量的差异来解释。吸烟和锻炼等行为变量解释了性别间体重差异的最大部分。然而，对于性别内种族间的体重差异，社会经济地位和背景变量对肥胖差异具有最大的解释力，而背景变量在解释体重不足差异方面发挥着关键作用。这些结果表明，消除肥胖和体重不足的差异需要针对特定群体制定针对性的政策。 (C) 2014 Elsevier B.V. 保留所有权利。
Using data from the National Income Dynamics Study, we document differentials in both underweight and obesity across race and gender in post-Apartheid South Africa. Using a nonlinear decomposition method, we decompose these differences across gender within race and then across race within gender. Less than one third of the differences in obesity and underweight across gender are explained by differences in covariates. In contrast, at least 70% of the obesity differences across race are explained by differences in covariates. Behavioral variables such as smoking and exercise explain the largest part of the bodyweight differentials across gender. For bodyweight differentials across race within gender, however, socioeconomic status and background variables have the largest explanatory power for obesity differentials, while background variables play the key role in explaining the underweight differentials. These results indicate that eradicating obesity and underweight differentials will require targeting policies to specific groups. (C) 2014 Elsevier B.V. All rights reserved.
