Objectives : To investigate the relationship between the degree of vitamin D deficiency and psychiatric symptoms among psychiatric inpatients. Studies on the association of vitamin D status with mental illnesses have been reported. However, the relationship of hypovitaminosis D with measures of depressive symptoms and cognitive functions remains unclear.
Methods : A sample of 108 psychiatric inpatients were enrolled with a manner of a retrospective study. Using serum levels of 25-hydroxyvitamin D [25(OH)D] and scores on the BDI and MMSE, an association between vitamin D level and depressive symptoms/cognitive declines were evaluated with Fisher’s exact tests and Pearson’s correlation analysis.
Results : Sixty-seven patients (62%) were classified as deficient in vitamin D. Serum 25(OH)D concentrations did not reveal significant difference between the groups. Additionally, there was no significant correlation between serum 25-OH vitamin D level and depressive symptoms and cognitive functions.
Conclusion : Vitamin D deficiency is common among psychiatric patients, independent of diagnostic category. Even though the role of vitamin D in psychiatric disorders is unclear, concerns about vitamin D deficiency and psychiatric approaches are necessary. Future studies on the relationship between vitamin D deficiency and major psychiatric symptoms are needed.
