Abstract
Background: China's obesity rate has grown "explosively" in the past few decades, and overtime work has become the norm for urban workers in China. It is of great significance to investigate the influence of working hours on obesity in order to prevent obesity and regulate the labor market. Methods: Based on the 2018 China Family Panel Studies, this paper first uses the logit regression method to investigate the effect of working hours on obesity of urban workers in China, and then uses the intermediary effect model to investigate the intermediary effect of weekly exercise time and sleep time. Finally, heterogeneity was analyzed for different gender and income groups. Results: (1) Urban workers who work more than 40 hours a week are more likely to be obese than those who work less than 40 hours a week. (2) The Mediator Model found that: in the conduction mechanism of working hours affecting obesity, week exercise time (less than 30 minutes per day) and sleep time (less than 8 hours per working day) both serve as a mediator, and the mediating effect of exercise time is greater than that of sleep time. That means, working more than 40 hours a week cannot only directly increase the risk of obesity among urban workers, but also indirectly increase their risk of obesity by reducing their exercise time and working-day sleep time. (3) A heterogeneity regression analysis found that, compared with urban workers who work less than 40 hours a week, working more than 40 hours a week has a greater impact on obesity among women and low-income groups. Conclusions: The above studies show that, obesity as a complex multifactorial disease, not only genetic, dietary and environmental factors should be taken into account, but also employee week work hours should be considered as a potential risk factor.
