Background: Vitamin D defciency is highly prevalent among Japanese female university students. Vitamin D defciency is associated with physical and mental health problems, including sleep disorders. This study aimed to clarify the relationship between vitamin D defciency and sleep and mental health problems among Japanese female university students. Methods: Participants were 224 female university students. Blood levels of 25-hydroxyvitamin D [25(OH)D] were measured using liquid chromatography-tandem mass spectrometry for vitamin D assessment. Mental health was assessed using the K6. Sleep–wake status as a factor related to mental health was assessed using the Athens Insomnia Scale (AIS) and Munich ChronoType Questionnaire. Loneliness was assessed using the Three-Item Loneliness Scale. Factors predicting mental health problems with a K6 score≥5 were explored using the Mann–Whitney U test, Fisher’s exact probability test, and classifcation and regression tree (CART) analysis. Results: The median (interquartile range) serum 25(OH)D concentration was 14.5 (11.8–18.3) ng/mL. Of the participants, 80.8% had vitamin D defciency (25(OH)D<20 ng/mL), and 26.3% had severe vitamin D defciency (25(OH) D<12 ng/mL). In total, 41.1% had mental health problems with a K6 score of≥5. Although there was no signifcant association between vitamin D defciency and sleep–wake problems, vitamin D defciency was more prevalent among those with K6 scores≥5 (P=0.02). Compared to those with K6<5, those with K6≥5 had signifcantly higher Loneliness and AIS scores (P<0.001), greater social jetlag (P=0.03), shorter sleep duration on weekdays (P=0.03), and lower serum 25(OH)D concentration (P=0.02). In the CART analysis, the algorithm was set in the order of Loneliness score≥6, AIS score≥7, social jetlag≥150 min, and serum 25(OH)D concentration<14 ng/mL, and the target accuracy (95% confdence interval: CI) was 76.5 (70.3–81.9)%, and sensitivity and specifcity (95% CI) were 62.2 (51.4–72.2)% and 86.3 (79.2–91.6)%, respectively. Conclusions; Loneliness, insomnia symptoms, social jetlag, and vitamin D defciency were associated with mental health problems among Japanese female university students. |
