Abstract

A cross-sectional study has been conducted in 210 pregnant women at 5 communes of
Dai Tu district, Thai Nguyen province to determine the prevalence of vitamin D deficiency.
Serum 25(OH) D was measured by HPLC method.
Results: The prevalence of vitamin D
deficiency 25(OH) D <50 nmol/L was 22.4%, among them: 21% had mild vitamin D deficiency and 1.4% had moderate vitamin D deficiency. Prevalence of vitamin D insufficiency, 25(OH) D between 50-74.9 nmol/L, in pregnant women was 50.0%. Pregnant
women who were not farmers had 72% increased risk for vitamin D deficiency (OR=0.28;
95% CI: 0.12-0.69; p<0.001). Singleton pregnant women had 1.58 times higher risk for
vitamin D deficiency (OR=1.58; 95% CI: 1.16-2.15; p<0.01).
Conclusions: Vitamin D
deficiency and insufficiency are common among pregnant women. The prevention of micronutrient deficiency especially vitamin D deficiency should be promoted by appropriate
interventions to improve the micronutrient status for pregnant women
