Associations of sunlight affinity with depression and sleep disorders in American males: Evidence from NHANES 2009-2020.

ABSTRACT:

Objective

Depression and sleep disorders are globally prevalent, yet male-specific studies remain scarce. This study investigates associations between sunlight affinity (a novel dual-dimensional metric comprising psychological [sunlight preference score, SPS] and behavioral [sunlight exposure duration, SED] dimensions) and subthreshold depression (StD), major depressive disorder (MDD), short sleep, and trouble sleeping in American males.

Methods

We analyzed weighted data from 7,306 males in the National Health and Nutrition Examination Survey (2009-2020) and assessed sunlight affinity's associations with depression and sleep disorders based on multiple logistic regression, threshold effects analysis, restricted cubic spline (RCS) analysis, subgroup analysis, and mediation an
