Pollution… how depressing!

A French epidemiological study conducted on 123,764 participants from the Constances cohort (1) recently showed that a continuous and high exposure to fine particles (PM2,5), black carbon (BC) and nitrogen dioxide (NO2) was significantly associated with depressive symptoms. This association was all the stronger among men, especially single people with low income and level of education.
Very bad news as the urbanization of populations (associated with greater exposure to air pollution) continues to increase, while depression is ranked as the leading cause of morbidity (and disability) in the world.
More than half of humanity now lives in cities, and by 2050, it will be two thirds! These results are a real public health warning signconclude the researchers who invite political decision-makers to support the implementation of targeted interventions for the prevention of mental illness in particularly polluted areas.
It is true, we feel like adding, that if public policies do not effectively reduce the exposure of the population to atmospheric pollutants, such provisions would be the lesser evil. But will this be one of the priorities of governments?
