Key clinical point: Low vitamin D levels appear to be associated with depression in adolescents.
Major finding: Odds of depression dropped 10% for every additional 10 nmol/L of serum vitamin D levels in adolescents (OR, 0.90).
Study details: The findings are based on a cross-sectional cohort study using 2005-2010 NHANES data on vitamin D levels and major depressive disorder prevalence in adolescents aged 12-17.
The research was funded by the Denver Health Division of General Pediatrics. The authors had no relevant financial disclosures.
