Air pollution and depressive symptomatology: Exploratory analyses of intervening psychosocial factors

Exploratory modelling revealed associations of individual perceptions, social factors, and physical components of air pollution with depressive symptomatology. Residents of the Los Angeles Metropolitan Area who have experienced a recent, undesirable life event and who perceive poor air quality in their neighborhood have greater symptoms of depression. These effects control for socioeconomic status and prior psychological status. In addition we show that perceived air quality is a function of both toxic components of ambient air as well as individual psychosocial experiences.This research was supported by the National Institute for Mental Health (MH 28924-10A1) and the Southern California Edison Health Effects Research Laboratory (J-1909902).
