ISGlobal: Long-term exposure to air pollution may increase the odds of depression


News from ISGlobal


A greater probability of developing depression following long-term exposure may be added to the long list of negative health effects already attributed to air pollution. This is the conclusion of a study published in the International Journal of Hygiene and Environmental Health led by a team from the ISGlobal).

The team’s main objective was to investigate the possibility of associations between long-term exposure to air pollution and a history of depression or anxiety disorders. They compared data on levels of exposure to various ambient air pollutants in Barcelona with information collected in the course of interviews with nearly 1000 people resident in the city aged between 45 and 74 years. The study group were volunteers belonging to the ALFA (Alzheimer and Families) cohort who participated in several studies related to Alzheimer disease undertaken by the Pasqual Maragall foundation.

The results show a significant association between long-term exposure to air pollution (NOx, NO2, PM2.5 and PM10), a history of depression and the use of antidepressants.
