ABSTRACT
BACKGROUND: Vitamin D insufficiency and deficiency are highly prevalent in populations with HIV, but there is limited data on predictors for suboptimal levels. METHODS: To determine risk factors for Vitamin D insufficiency/deficiency, 185 charts were retrospectively reviewed. RESULTS: Proportions with Vitamin D levels < 10 ng/ml, 10 - 20 ng/ml, 20 - 30 ng/ml and > 30 ng/ml were 14.6%, 44.8%, 24.9%, and 15.7%, respectively. Bivariate analysis showed that Vitamin D levels < 20 ng/ml were associated with a lower albumin level (p =.02), female gender (p = .0003), and African-American (AA) race (p = .0001). Tenofovir exposure showed borderline significance (p = .09). AA race was the only significant factor in multivariate modeling. CONCLUSIONS: Vitamin D insufficiency/deficiency was high. AA race was an independent risk factor. Although not significant, obese persons with a poorer nutritional status and possibly those on tenofovir may also be at higher risk.
