Impact of Continuously Improved Air Quality on Mental Health: A Quasi-experimental Study Based on Longitudinal Observations for Chinese Adults.

ABSTRACT: Long-term exposure to fine particulate matter (PM_2.5) has been linked with adverse mental health outcomes. However, questions remain regarding the nature of lagged effects over time and by extension potential benefits over time of continued reduction in pollution. Here, we aim to estimate the long-term association between exposure to PM_2.5 and depressive symptoms in China utilizing longitudinal models for prolonged exposures as well as a quasi-experimental design utilizing data from 23151 participants over 4 longitudinal waves that occurred in 124 cities in China between 2011 to 2018. Mixed-effects models as well as distributed lag nonlinear mixed models were fitted to assess the relationship between PM_2.5 and depressive symptoms. We also assessed the effec
