Background Considering the high prevalence of both vitamin D deficiency (VDD) and sleep
impairment in children and adolescents, this study was conducted to determine the
association between VDD and sleep duration in the Iranian pediatric population. Methods
This multicentric national study was conducted in 2019 on 2564 frozen sera obtained from 7
to 18-year students who were studied in the fifth survey of a national school-based
surveillance program conducted in 30 provinces of Iran. Sleep duration was assessed using …

Background
Considering the high prevalence of both vitamin D deficiency (VDD) and sleep impairment in children and adolescents, this study was conducted to determine the association between VDD and sleep duration in the Iranian pediatric population.
Methods
This multicentric national study was conducted in 2019 on 2564 frozen sera obtained from 7 to 18- year students who were studied in the fifth survey of a national school-based surveillance program conducted in 30 provinces of Iran. Sleep duration was assessed using a questionnaire based on the World Health Organization-Global School-based Student Health Survey protocol. Short sleep duration was defined as sleep duration less than 8 h/day VDD Vitamin D < 20 ng/dL, and vitamin D insufficiency as 20–30 ng/dL.
An adjusted logistic regression model was applied to evaluate the associations of vitamin D status with sleep duration.
Results
The Mean (SD) of students’ age was 12.1(3.0) years; overall 10.6%of participants had VDD and 23% of participants had short sleep duration. in the adjusted logistic model, students with a low level of vitamin D (insufficient and deficient) had a higher odds of short sleep duration in comparison to those with normal vitamin D level (OR: 1.29, 95%CI: 1.02–1.62).
Conclusion
The current study showed that low Vitamin D levels (insufficient and deficient)were significantly associated with short sleep duration in school-aged children. Further studies are recommended to determine the efficacy of vitamin D replacement in improving sleep duration and quality.
