Brief Summary

According to a national study in 2002, the prevalence of ID, IDA, and ID+IDA among pregnant women in China was 42.6%, 9.1%, and 61.7% respectively. A similar study in Hebei province at the same time showed that the prevalence of IDA among pregnant and lactating mothers was 46.39% and 47.21% respectively. There was a significant difference between urban and rural areas. Women living in rural areas had higher chances of having IDA (p\<0.01). WHO and UNICEF recommend taking iron, folic acid and multiple micronutrients during pregnancy. However, we don't know much about their influence on maternal and infant health and their clinical effectiveness. Health Department of China recommends taking 400ug folic acid before pregnancy and during early pregnancy. But for various reasons, not all expecting mothers take this advice. Besides, we don't have a national level technical standard of how to take nutrition supplements during pregnancy. Therefore, it's crucial for us to study if iron/folic acid or folic acid only can prevent perinatal complications, as well as their influences on infant and toddler health. The purpose of this study is to test whether taking iron/folic acid and folic acid only from early pregnancy until delivery will lower the chances of pregnancy complications, and to see how supplements affect gestation results. As well, it will evaluate a) whether taking iron supplement during pregnancy can prevent IDA during pregnancy; b) whether taking iron supplement can increase mother and fetus iron storage; and c) how mother's iron level affects newborn's iron level. We hope to understand nutrition conditions during pregnancy and investigate the relations between pregnancy diet and complications during pregnancy, weight gain during pregnancy, and newborn birth weight. We will evaluate the influence of taking iron and folic acid during pregnancy on the health of infants and toddlers.
