China owns a huge labor force of around half billion workers in 2018. However, little is known about the prevalence of obesity and the association between obesity and economic status in this special population. By employing the concentration index (CI) and decomposition analysis, this paper addresses this knowledge gap by using the most recent nationally representative dataset. In specific, this study examines the prevalence of obesity and the socioeconomic gradient in the probability of obesity among Chinese workers between 16 and 65. Our results show that the prevalence of obesity is completely different by using a different measure: the overall prevalence of being general obesity (measured by body mass index, BMI ≥ 28) varies by gender and residency from a minimum of 5.88% to a maximum of 9.46%, whereas abdominal obesity (measured by waist circumference, WCmale ≥ 85 cm & WCfemale ≥ 80 cm) prevalence presents a socking level from 64.53% to 67.69%. Moreover, the results show a pro-rich distribution of obesity (general and abdominal) among male workers (CI = 0.112; CI = 0.057) and a pro-poor distribution among female workers (CI = -0.141; CI = -0.166). We also find that the direction of the contribution of socioeconomic factors to income-related inequalities in obesity differs by gender. These results have substantial implications for the measurement of socioeconomic inequality in adiposity and for improving health-related policies targeting the Chinese labor force.
2018 年，中国拥有约 5 亿劳动力。然而，对于这个特殊人群中肥胖的流行程度以及肥胖与经济地位之间的关系，人们知之甚少。本文利用集中指数（CI）和分解分析，利用最新的全国代表性数据集来填补这一知识空白。具体来说，本研究考察了中国 16 至 65 岁工人中肥胖的流行程度以及肥胖与经济地位之间的社会经济梯度。我们的研究结果表明，采用不同的衡量标准，肥胖的流行程度有很大的不同：总体肥胖（通过身体质量指数 BMI≥28 来衡量）的流行率因性别和居住地而异，最低为 5.88%，最高为 9.46%，而腹型肥胖（通过腰围 WCmale≥85cm&WCfemale≥80cm 来衡量）的流行率则令人震惊，高达 64.53%至 67.69%。此外，研究结果表明，男性工人的肥胖（普通肥胖和腹型肥胖）呈富有的分布（CI=0.112；CI=0.057），而女性工人的肥胖呈贫穷的分布（CI=-0.141；CI=-0.166）。我们还发现，社会经济因素对肥胖相关收入不平等的贡献方向因性别而异。这些结果对衡量肥胖的社会经济不平等以及改善针对中国劳动力的与健康相关的政策具有重要意义。
