Recent studies link vitamin D deficiency with depression; however evidences from the Nepalese population are scarce. The current study explored the association between vitamin D deficiency and depression among 300 adults of 18 years and above age residing in eastern Nepal. Validated Nepali version of the Beck Depression Inventory scale (BDI-Ia) was used to determine depressive symptoms and a BDI cutoff score of >= 20 was considered as clinically significant depression. Sociodemographic data were collected using semi-structured questionnaire. Blood samples were collected to measure serum 25-hydroxy vitamin D (25(OH)D) and classify vitamin D status (deficient, insufficient and sufficient). We used Chi-square test to identify the association of socio-demographic variables and vitamin D status with clinically significant depression. We found a significant association of gender, geographical location of residence, marital status, religion and vitamin D status with clinically significant depression. Binary logistic regression model was used to examine the likelihood of clinically significant depression among vitamin D deficient individuals. Vitamin D deficiency was significantly associated with increased odds of clinically significant depression even after adjusting for confounding variables. This finding suggests Vitamin D deficient people have increased odds of having clinically significant depression.
