We used a new conceptual framework that integrates tenets from health economics, social epidemiology, and health behavior to analyze the impact of socioeconomic forces on the temporal changes in the socioeconomic status (SES) gap in childhood overweight and obesity in China. In data from the China Health and Nutrition Survey for 1991 to 2006, we found increased prevalence of childhood overweight and obesity across all SES groups, but a greater increase among higher-SES children, especially after 1997, when income inequality dramatically increased. Our findings suggest that for China, the increasing SES gap in purchasing power for obesogenic goods, associated with rising income inequality, played a prominent role in the country's increasing SES gap in childhood obesity and overweight.
我们使用了一个新的概念框架，该框架整合了健康经济学、社会流行病学和健康行为学的原理，分析了社会经济因素对中国儿童超重和肥胖的社会经济地位（SES）差距的时间变化的影响。在中国健康与营养调查（CHNS）1991 年至 2006 年的数据中，我们发现所有 SES 群体的儿童超重和肥胖的流行率都在增加，但高 SES 儿童的增长幅度更大，尤其是在 1997 年收入不平等急剧增加之后。我们的研究结果表明，对于中国来说，与收入不平等相关的购买致肥胖商品的购买力的 SES 差距不断扩大，在中国儿童肥胖和超重的 SES 差距不断扩大中发挥了重要作用。
