The associations of trouble sleeping, biological age acceleration with depressive symptoms: Evidence from three cohorts.
Sleep problems and biological aging accelerate together to worsen depression risk, suggesting treating both sleep and aging processes jointly could prevent mood disorders.
Using evidence from three large cohort studies, this analysis demonstrates that self-reported sleep difficulties and biological age acceleration (PhenoAge or similar aging clock-based metric) are independently associated with depressive symptoms, with individuals experiencing both exposures showing compounded depression risk. The findings support integrated interventions targeting sleep and biological aging simultaneously as a prevention strategy for depression.

Why it surfaced
Three-cohort replication of biological age acceleration and sleep as depression risk factors; relevant to aging watchlist; moderate novelty given many similar papers; solid multi-cohort design adds confidence.
