| Outline of Final Research Achievements |
We investigated the relationship serum folate levels and birth defects in 15,037 mother child pairs, where information on lifestyle factors and maternal folate uptake in the first trimester of pregnancy was available, and where children were singleton births born after 22 gestational weeks. Participants were selected from the 20,929 mother-child pairs enrolled in the Hokkaido Study of Environment and Children’s Health. Logistic regression analyses, both crud and adjusted (After adjusting for mother’s age, parity, social factors, alcohol consumption and smoking status during the first trimester), indicated no associations between serum folate levels were and any birth defcts. This results may be due to the small sample size. Further studies will include investigations on relationship between maternal folate-related gene polymorhisms, folate intake during the first trimester of pregnancy and birth defects.
