Background: Hypovitaminosis D levels have been implicated in a wide array of psychiatric disorders. Yet, the relationship between vitamin D levels and antenatal psychiatric disturbances is ambiguous. This study aimed to identify the psychosocial and clinical factors associated with antenatal hypovitaminosis D. Methods: A total of 169 of pregnant women was recruited from Zagazig University Obstetrics and Gynecology Outpatient clinics, Egypt, where they received their antenatal care. The psychometric measures included Hamilton Anxiety Rating Scale, Zagazig Depression Scale, Beck Scale for Suicide Ideation and Structured Clinical Interview for DSM-IV-TR Axis I Disorders for assessment of associated anxiety and depressive symptoms, current suicide ideation and psychiatric disorders, respectively. Serum 25(OH)D levels were measured using ELFA technique. Results Around 57% of women had antenatal hypovitaminosis D. Those with hypovitaminosis D were likely to be of lower income (P=0.023), exposed to intimate partner violence (IPV) (P=0.009), and experienced higher levels of anxiety (P=0.006). Logistic regression confirmed the association between hypovitaminosis D and history of IPV exposure (OR 2.0, 95% CI: 1.1, 3.9), and comorbid anxiety symptoms (OR 2.4, 95% CI: 1.0, 6.2). Predictors of IPV exposure in women with antenatal hypovitaminosis D were lower education (P=0.045), unplanned pregnancy (P=0.016), anxiety symptoms (P=0.036), and current suicide ideation (P<0.001). Conclusions: Antenatal hypovitaminosis D was prevalent among pregnant women. It would predict IPV exposure and comorbid anxiety symptoms. Women, as part of their antenatal assessment, should be regularly screened for vitamin D insufficiency, IPV exposure, and associated affective symptoms.
