Abstract
OBJECTIVE: To evaluate the prevalence and predictors of low vitamin D status among pregnant women with HIV infection. METHODS: The present cross-sectional study analyzed repository specimens collected at 12-34 weeks of pregnancy among women enrolled across 17 sites in Latin America and the Caribbean between 2002 and 2009. Logistic regression modeling was used to identify factors associated with low vitamin D status (25-hydroxyvitamin D <30 ng/mL). RESULTS: Among 715 women, 218 (30.5%) were vitamin D deficient (<20 ng/mL) and 252 (35.2%) were insufficient (21- /mL). Factors associated with low vitamin D status included residence in subtropical latitudes (adjusted odds ratio [aOR] 1.97, 95% confidence interval [CI] 1.35-2.88), assessment during non-summer seasons (autumn: aOR 1.85, 95% CI 1.20-2.86; spring: 4.3, 2.65-6.95; winter: 10.82, 5.74-20.41), employment (aOR 1.56, 95% CI 1.06-2.38), and assessment before 20 weeks of pregnancy (aOR 1.89, 95% CI 1.18-3.06). Factors protective against low vitamin D status were CD4 count below 200 cells per mm(3) (aOR 0.45, 95% CI 0.26-0.77) and protease inhibitors (aOR 0.62, 95% CI 0.40-0.95). CONCLUSION: Low vitamin D status was prevalent among pregnant women with HIV infection. Further studies are warranted to identify the impact of low maternal vitamin D status.
