(ORDO NEWS) — According to the study, there is a link between long-term exposure to polluted air and an increased risk of depression later in life.
Another reason to think about what pollutes our cities.
Xinye Qiu and colleagues conducted a population-based longitudinal cohort study of US Medicare patients over 64 years of age.
As part of the work, 8,907,422 people (mean age 73.7 years) were examined in the period from 2005 to 2016. By the end of the study, 1,526,690 participants had been diagnosed with depression.
The researchers found that, based on the tripollutant model, every 5 units increase in exposure to particulate matter, nitrogen dioxide, and ozone was associated with a percentage increase in depression risk of 0.91%, 0.61%, and 2.13%, respectively.
“We hope that this study may inspire other scientists to further consider possible environmental risk factors for preventing geriatric depression, for a better understanding of the disease in the future, and for improving mental health care for the elderly,” the authors write.
Recall that polluted air affects not only the psychological state in old age, but also the health of the population as a whole.
