Air quality and obesity at older ages in China: The role of duration, severity and pollutants.

Background

Population ageing and air pollution have emerged as two of the most pressing challenges in China. However, little evidence has explored the impact of air pollution on obesity among older adults in China.

Methods

The China Health and Retirement Longitudinal Study-a nationally representative sample of middle-aged and older Chinese was linked to the air pollution data at the city level.
