Physical activity may reduce depression severity linked to genetic risk

New research published in Nature Mental Health indicates that regular physical activity can mitigate the impact of genetic predisposition on the severity of depression symptoms. Researchers at the University of Texas at San Antonio analyzed data from over 23,000 adults participating in the National Institutes of Health’s All of Us Research Program, utilizing long-term fitness tracker data to ensure more accurate monitoring of daily habits compared to self-reported exercise logs.

The study found that individuals with the highest genetic risk for depression experienced the greatest benefits from staying active, showing significantly less severe symptoms than their less active counterparts. This suggests that lifestyle interventions could play a critical role in personalized medicine, potentially allowing clinicians to tailor exercise recommendations based on a patient’s genetic profile.

Separately, clinical challenges remain for the estimated 322 million people worldwide living with depressive disorders. While standard medications are effective for many, a segment of the population suffers from treatment-resistant depression. For these individuals, medical professionals are increasingly looking toward alternative interventions, such as repetitive transcranial magnetic stimulation (rTMS), when traditional antidepressants fail to alleviate symptoms.
