Short-Term Exposure to PM_2.5 Chemical Components and Depression Outpatient Visits: A Case-Crossover Analysis in Three Chinese Cities.

ABSTRACT:

Background

The association between specific chemical components of PM_2.5 and depression remains largely unknown.

Methods

We conducted a time-stratified case-crossover analysis with a distributed lag nonlinear model (DLNM) to evaluate the relationship of PM_2.5 and its chemical components, including black carbon (BC), organic matter (OM), sulfate (SO₄^2-), nitrate (NO₃^-), and ammonium (NH₄⁺), with the depression incidence. Daily depression outpatients were enrolled from Huizhou, Shenzhen, and Zhaoqing.

Results

Among 247,281 outpatients, we found the strongest cumulative effects of PM_2.5 and its chemical components with the odd ratios (ORs) of 1.607 (95% CI: 1.321, 1.956) an
