Abstract:

Objective To investigate the anemia and levels of related micronutrients of pregnancy women and analyze the effects of anemia at different stages of gestation on physical indexes of neonates. Methods The fasting venous blood of 5 mL was drawn from 299 pregnancy women of Tongliang Country, Chongqing for detecting the hemoglobin and micronutrients related to anemia. The pregnancy outcomes and physical indexes of neonates were followed up. Results Among 299 pregnant women, the rates of vitamin A deficiency, marginal vitamin A deficiency, iron deficiency, and vitamin B12 deficiency were 11.0% (33/299), 43.8% (131/299), 5.7% (17/299), and 0.3% (1/299), respectively. The incidence of anemia during gestation period was 24.5%（62/253）. The levels of plasma vitamin A and iron of early pregnancy anemia group were significant lower than those of non-anemia group (P<0.05). The birth weights of neonates of late pregnancy anemia group were statistically lower than those of non-anemia group (P<0.05). Conclusion The incidences of anemia, vitamin A deficiency, and iron deficiency during gestation period are still high in Tongliang Country, Chongqing. The guidance of gestation dietary should be strengthened and the anemia should be treated in time so as to ensure the health of both mothers and fetuses.
