Associations of mood, stress, and social support with sleep duration and daytime sleepiness among adolescents in semi-rural Georgia.

Objective: Adolescents are at greater risk for poor sleep compared to childhood; however, there is limited data regarding psychosocial determinants of adverse sleep health among semi-rural adolescents. We investigated associations of mood, stress, and social support with self-reported sleep duration and daytime sleepiness among adolescents. Methods: Adolescents ( Results: Most participants were non-Hispanic White (55%), female (53%), and approximately 35% were eligible for free-reduced lunch. Mean sleep duration (± SD) and daytime sleepiness was 8.04 ± 1.36 and 5.17 ± 2.37, respectively; and 42% of participants reported insufficient sleep (<8 h). Depressive (β = 0.13, 95% CI: 0.08, 0.18) and anxiety (β = 1.20, 95% CI 0.51, 1.88) symptoms, and stress (β = 1.97, 95% CI 1.21, 2.74) were associated with higher sleepiness scores. The psychosocial factors were associated with higher odds of insufficient sleep duration, but not continuous sleep duration. Higher social support was associated with lower sleepiness, but not sleep duration. There was no observed effect modification by social support. Conclusions: Experiences of psychosocial factors were associated with more sleepiness and insufficient sleep, while social support was associated with less sleepiness. Future studies should explore intervention strategies to enhance mood and social support and reduce stress to improve sleep among semi-rural adolescents.
