Worldwide research in down syndrome have shown that advanced maternal age (˃30 years) at conception, lower folate status and/or impaired folate metabolism, maternal weight gain during pregnancy, low socioeconomic conditions, radiation exposure, use of contraceptive pills, and taking tobacco/smoking are major maternal risk factors for giving birth child with DS. However, the occurrence of those factors in pregnant women at advanced age has not yet been investigated in Bangladesh. Therefore, a large scale study was needed to explore the overall scenario in Bangladesh. This pilot cross sectional study was aimed to determine the serum folate and homocysteine status at advanced age pregnant women. We measured serum folate and homocysteine concentrations using the Enzyme-Linked Immunosorbent Assay (ELISA). Out of 70 pregnant women, serumfolate level was low (<5 ng/ml) in 13 (18.57%), intermediate (5-6.9 ng/ml) in 8 (11.43%) and normal in 49 (70%) whereas homocysteine concentrations were found low (<5 ng/ml) in all participants. Finally, questionnaire data indicates, low socioeconomic status, overweight during pregnancy, taking contraceptive pills and taking tobacco/smoking was higher percentage in folate-deficient pregnant women than normal serum folate level women. Additionally, women (n=13) with low folate level belongs to low socioeconomic status, overweight, taking contraceptive pills and tobacco/smoking did not give birth child with DS phenotypes. Together, our preliminary findings give an overview of DS associated risk factors in Bangladeshi pregnant women. Large scale study is going on. In next study, we might able to investigate DS risk factors, their associations with serum folate and homocysteine levels and finally with DS phenotypes in child throughout the country.
