Premature aging linked to disadvantaged neighbourhoods and depression symptoms
Feeling depressed and living in a deprived urban neighbourhood could be making you age faster, according to a new study led by researchers at McMaster University. The findings, showed that living in urban environments marked by material and social inequities, and having depression symptoms, were independently associated with premature biological aging, even after accounting for individual-level health and behavioural risk factors, such as chronic conditions and poor health behaviours.
Depressive symptoms in the study were measured using a 10-item standardized depression scale. The researchers found an acceleration in the risk of death by one month for every point increase on the depressive symptom score. They theorized that emotional distress caused by depression may result in more biological wear and tear and dysregulation of physiological systems, which in turn could lead to premature aging.
