Job Strenuousness and Obesity: The Case of a Developing Country
利用印尼家庭生活调查数据，发现工作强度与肥胖负相关，但该关系源于低社会经济地位工人被选入高强度工作，而非因果效应，提醒发展中国家慎用发达国家结论。
This paper analyses the Indonesian Family Life Survey to show that job strenuousness is negatively related to obesity, which is largely consistent with the literature. However, this paper does not interpret the relationship as causal. Instead, efforts are made to demonstrate that the relationship is attributable to sample selection: workers with low socioeconomic status are lightweight and selected for strenuous jobs. This paper warns against reflexive applications of the conclusions derived from the developed world to the developing world. Our results imply that sedentariness at work probably plays a small role in the prevalence of obesity in the region.
