How long-term air pollution and its metal constituents affect type 2 diabetes mellitus prevalence? Results from Wuhan Chronic Disease Cohort.

Background: Epidemiological evidence linking type 2 diabetes mellitus (T2DM) with air pollution is discrepant and most are restricted to the influences of air-pollutant mass concentration. This study aims to explore the effects of long-term exposure to air pollution and its metal constituents on T2DM prevalence in China.

Methods: We used data on 10,253 adult residents from the baseline survey of Wuhan Chronic Disease Cohort in 2019.

Association of depressive symptoms with ambient PM in middle-aged and elderly Chinese adults: A cross-sectional study from the China health and Retirement Longitudinal Study wave 4.

Depressive symptoms have become a serious public health issue worldwide. Several studies showed that air pollution, especially fine particulate matter (PM), may be a risk factor of mental disorders. However, existing studies reported inconsistent results and little evidence is available in developing countries, like China.
