Association of Short-Term Exposure to Air Pollution with Depression in Patients with Asthma: A Cross-Sectional Study in Delhi, India
Year: 2024
Type: article
Study design: Observational Study
Abstract: Background: Patients with asthma are a population at risk for depression and subsequent mental health risks. Previous studies have suggested that exposure to air pollution is associated with lower asthma control and a higher risk of depression. There is limited evidence on the effect of short-term exposure to air pollution on mental health in susceptible populations, such as patients with asthma. Objectives: ) to air pollution and depression in patients with asthma. Methods: ) were procured from Central Pollution Control Board (CPCB) air quality monitors, and 1-month average exposures were computed using inverse distance weighting (IDW) based on participant residence and workplace address. Ordinal and binary logistic regressions were respectively used to assess the associations for depression status and asthma control with per-unit interquartile range (IQR) increase of air pollution exposure. Sensitivity analyses were conducted using two-pollutant models and mediation effects were evaluated using the Karlson-Holm-Breen method. Results: exposure was not associated with depression status or asthma control. Conclusions: Our study shows that greater short-term exposure to air pollution may be associated with increased odds of depression and uncontrolled asthma in patients with asthma. Further studies are required to replicate our results and confirm this association. https://doi.org/10.1289/JHP1003.
