Patterns of Vitamin D Deficiency in a Community Outpatient Psychiatric Practice: a Real-World Evaluation of Treatment Gaps

Vitamin D is traditionally recognized for its role in bone mineralization but recent observations suggest additional pertinent functions in neuronal biology. The present study examines the rate and pattern of Vitamin D deficiency in the outpatient mental health clinic of a community teaching hospital as well as the vitamin D supplementation practices of outpatient psychiatrists. Participants include 148 consecutive psychiatric outpatients. Individuals with conditions that alter the metabolism of vitamin D were excluded from the study as are those who may be taking medications that influence Vitamin D metabolism. Statistical analysis was performed using the SPSS 25th edition, statistical significance set at p < 0.05. The majority of patients in the study were between 41 and 65 years old (n = 91, 61.5%), African American (n = 120, 81.1%) and female (n = 80, 54.1%). The median level is 23.7 ng/ml. As defined by the Endocrine Society’s Clinical Practice Guidelines, 68.2% of the population had insufficient and deficient Vitamin D levels (32.4% and 35.8% respectively), 62.4% of whom were not prescribed any Vitamin D supplementation and of this untreated group, 84% were African Americans. No clinical or demographic characteristics showed any statistical difference in both the “treated” and “not treated groups”. Logistic regression did not reveal any significant predictors for Vitamin D deficiency. Vitamin D deficiency remains a significant issue among patients with psychiatric disorders. Our findings show gaps in Vitamin D deficiency treatment and recommend that future studies examine physician prescription practices in light of the racial disparity in Vitamin D deficiency treatment oberved in this study.
