Effects of pre-pregnancy overweight and obesity of mothers and infants on iron-deficiency anemia in infants
Objective:To observe the effect of maternal overweight and obesity before pregnancy and infant overweight and obe-sity on Iron-deficiency anemia in infants under 2 years old.To provide clues and basis for community maternal and child health care and reduce the incidence of Iron-deficiency anemia in children.Methods:A retrospective Cohort study was conducted on 611 pairs of mothers and children who underwent physical examination at the Waitan Street Health Service Center in Huangpu District of Shanghai from January 1,2021 to December 31,2023.The data of pre pregnancy body mass index(pBMI),weight,height,hemoglobin and calculated length weight of the offspring within 2 years old were extracted,and the correlation between pre pregnancy and infant overweight and obesity and infant Iron-deficiency anemia was analyzed by logistic regression.Results:In the logistic regression analysis with the mother's pBMI as an independent variable,compared with the normal pBMI,the AOR of pre pregnancy overweight and obesity on the risk of Iron-deficiency anemia in infants aged 6 months,1 year,and 2 years old was 2.426;2.314;4.369,95%CI(1.351,4.356);(1.125,4.761);(1.261,15.137);In the logistic regression analysis with infant overweight and obesity as independent variable,overweight and obesity of children at the age of 1 and 2 sig-nificantly increased the risk of Iron-deficiency anemia of children(AOR=2.537);4.159,95%CI(1.186,5.429);(1.205,14.348),P＜0.05.Conclusion:Pre-pregnancy overweight and obesity of mothers and overweight and obesity of infants are independent risk factors for the occurrence of Iron-deficiency anemia in infants aged 1 and 2 years.
