Prevalence of micronutrients deficiency and micronutrient intake in pregnant women / Монголын Анагаах Ухаан

ABSTRACT

Background@#In order to study and evaluate the nutrition situation of the Mongolian people. The 2016-2017 NNS V includes 5 different age groups from Mongolian’s four economic development regions and Ulaanbaatar. The NNS V survey quantifies the prevalence of the nutrition conditions that are of greatest concern to the population, particularly young children and pregnant women.@*Goal@#To establish the prevalence of micronutrients deficiency and estimate micronutrient intake in pregnant women@*Materials and Methods@#Totally 2220 pregnant women included in cross-sectional study from urban and rural area. Survey procedures consisted of interview, anthropometric measurements, clinical examinations, and the collection of biological (blood and urine) samples for pregnant women. Micronutrient deficiencies were assessed by tests for hemoglobin, serum, ferritin, soluble transferrin receptor (sTfR), retinol-binding protein (RBP), 25-hydroxyvitamin D {25(ОН)D}, spot urine samples for determination of urinary iodine concentration.@*Result@#The prevalence of anemia, as measured by hemoglobin, was 21.4% and the iron deficiency anemia (IDA) was 10.5%, as measured by adjusted serum ferritin or soluble transferrin receptor (sTfR) was 29.6%. </br> Prevalence of iron deficiency as measured by serum ferritin was also highest in Western 35.1% and lowest in Eastern region 21.5% (P<0.01). The prevalence of vitamin D in pregnant women was high with 75.4% and 4.4% of all pregnant women had sufficient vitamin D status. An additional 20.2% of pregnant women having insufficient levels. The median concentration of 120.5µg/l indicates inadequate iodine status in pregnant women, as the desired range for adequate iodine nutrition in pregnancy 150-249 µg/l.@*Conclusion@#</br>1. One in every 5 pregnant women (21.4%) is anemic. </br>2. Vitamin D intake among pregnant women (7.3%) is very low, with 75.4% having vitamin D deficiency and vitamin D insufficiency –by 20.2%. </br>3. Median urinary iodine concentration of pregnant women is 120.2mg/l, considerably lower than WHO recommended reference range, indicating pregnant women are at risk of iodine deficiency. </br>4. Despite visible growth in vitamin and mineral supplements intake by pregnant women, compared to 2010, the infrequency of intake and failure to consume recommended number of supplements as instructed in the relevant guides persist.
