Key Points

  • The study aims to investigate how exposure to particulate matter influences depressive symptom trajectories over time.
  • Analyzed data from a national longitudinal survey in China.
  • Assessed individual and mixed exposures to particulate matter (PM) pollutants.
  • Examined the role of loneliness in mitigating depressive symptoms.
  • Higher exposures to PM pollutants are linked to increased risk of severe depressive symptoms.
  • Alleviating loneliness has a positive effect on reducing these depressive symptoms.
  • Coordinated control of PM pollutants is recommended to prevent worsening depressive symptoms.

Abstract

Exposures to individual and mixed PM pollutants increase the risk of severe depressive symptom trajectory groups, and reducing loneliness alleviates these effects. The findings underscore the need for further coordinated control of PM pollutants and alleviating loneliness to prevent depressive symptoms.
