Description
Summary:Objective The aim of this study was to examine the impacts of short-term exposure to air pollutants on hospitalizations for mental disorders (MDs) in Qingdao, a Chinese coastal city, and to assess the corresponding hospitalization risk and economic cost. Methods Daily data on MD hospitalizations and environmental variables were collected from January 1, 2015, to December 31, 2019. An overdispersed generalized additive model was used to estimate the association between air pollution and MD hospitalizations. The cost of illness method was applied to calculate the corresponding economic burden. Results With each 10 μg/m 3 increase in the concentration of fine particulate matter (PM 2.5 ) at lag05, inhalable particulate matter (PM 10 ) at lag0, sulfur dioxide (SO 2 ) at lag06 and ozone (O 3 ) at lag0, the corresponding relative risks (RRs) and 95% confidence intervals (CIs) were 1.0182 (1.0035–1.0332), 1.0063 (1.0001–1.0126), 1.0997 (1.0200–1.1885) and 1.0099 (1.0005–1.0194), respectively. However, no significant effects of nitrogen dioxide (NO 2 ) or carbon monoxide (CO) were found. Stratified analysis showed that males were susceptible to SO 2 and O 3 , while females were susceptible to PM 2.5 . Older individuals (≥ 45 years) were more vulnerable to air pollutants (PM 2.5 , PM 10 , SO 2 and O 3 ) than younger individuals (
