Objectives
Micronutrient Nutrition Status of Pregnant Women is very impotent for the health not only for pregnant women but also for infants, elimination of micronutrient deficiency in pregnant women is an important goal of ICN2.
Methods
China National Nutrition and Health Survey 2010-2013(CHNNS2010-2013) is a nationally representative cross-sectional study. It involved the random selection of 150 districts (urban) or counties (rural). The Hb, CRP and ferritin of 3500 healthy pregnant women were measured. Serum zinc concentrations of 1337 participants were measured by ICP-MS. Serum retinol concentrations of 1209 participants were measured by HPLC. Serum 25-hydroxyvitamin D levels of 1985 participants were measured by EIA kit.
Results
The national prevalence of anemia in pregnant women was 17.2%.The mean serum zinc level of the pregnant women was 739.7 µg/L and the deficient prevalence of zinc was 3.7 %. The mean serum retinol level of the pregnant women was 1.63 µmol/L and the prevalence of VAD was 5.3 %. The median serum 25-hydroxyvitamin D level was 15·5 ng/ml, with 74·9 % of vitamin D deficient.
Conclusions
Vitamin D deficiency is prevalent among pregnant Chinese women. Anemia is still the public-health issue in Chinese pregnant women. VAD is of mild public-health issue in Chinese pregnant women such as in the poor rural areas and low- income.
