Epidemiology studies have investigated the association between vitamin D and the risk of sleep disorders, but the results remain controversial. Therefore, we conducted this meta-analysis with the goal of clarifying the association between vitamin D and sleep disorders risk. All relevant studies were searched using PubMed, EMBASE, and Web of Science from inception to January 2018. Pooled odds ratios (ORs) and 95% confidence interval (CIs) were calculated using a fixed-effect model A total of nine studies (6 cross-sectional, 2 case-control, and 1 cohort studies) involving 9397 participants were included.
By comparing the lowest verse highest levels of serum vitamin D, we found that participants with vitamin D deficiency (VDD) had a significantly increased risk of s

  • sleep disorders (OR: 1.50, 95% CI: 1.31, 1.72).

Subgroup analysis showed that VDD also was associated with

  • poor sleep quality (OR: 1.59, 95% CI: 1.23, 2.05),
  • short sleep duration (OR: 1.74, 95% CI: 1.30, 2.32), and
  • sleepiness (OR: 1.36, 95% CI: 1.12, 1.65).

Subgroup analyses further indicated that serum 25(OH)D <20 ng/mL could significantly increase the risk of unhealthy sleep.
This meta-analysis suggest that vitamin D deficiency is associated with a higher risk of sleep disorders. More high-quality cohort studies and randomized controlled trials (RCTs) are needed to verify this association.
