Analysis Of Related Factors Of Iron Deficiency Anemia In Infants

Objective:To explore the epidemiological characteristics of children with iron deficient anemia(IDA)in the local area and to analyze its influencing factors,and provide a basis for the prevention and clinical diagnosis and treatment of the disease.Methods:All the 6-month-old and 12-month-old children who had their health examination at our health care department were recruited in this study.The hemoglobin level was tested,and a questionnaire was used to collect information regarding their birth histories,feeding patterns,and the home environments.Results:A total of 2491 children finished all the tests and the questionnaire,and 393children were finally diagnosed as IDA,indicating a prevalence of 15.8%in this district,mainly with mild anemia.IDA prevalence in the 6-month-old group(21.1%)was significantly higher than the 12-month-old group(10.6%),but had no sexy differences.The hemoglobin level in the 6-month-old group(115.73±9.03g/L)was significantly less than the 12-month-old group(120.02±9.12 g/L)(T=11.80,(49)<0.001).The height and weight of the anemia group were significantly lower than those of the normal group.(T=7.80.5.12,(49)<0.001)IDA prevalence of the 6-month-old children in the breast-fed group(17.5%)was significantly less than the mixed-fed group(24.9%)(?~2=8.77,(49)=0.003).IDA prevalence of the 12-month-old children in the breast-fed group(35.3%)and the mixed-fed group(31.3%)was significantly higher than and the formula-fed group(5.1%)(?~2=117.37,(49)<0.001)The univariate analysis showed that IDA prevalence in the 6-month-old group was associated with account location,premature birth,mother-education,feeding methods.When sex,birth history and other factors were controlled in multivariate-logistic regression analysis,there is an increased risk of anemia among local children than local children(OR=1.37,95%CI:1.03-1.82).Children whose mother,s degree of education is secondary school,compared to whose mother,s degree of education is college or older,the risk of IDA is increased.(OR=1.47,95%CI:1.08-1.99).Preterm birth increased the risk of anemia in infants.(OR=2.24,95%CI:1.28-3.91)Mixed-fed group are more at risk for anemia than breast-fed group.(OR=31.61,95%CI 1.18-2.18)The univariate analysis showed that IDA prevalence in the 12-month-old group was associated with account location,mother-childbearing age and feeding methods.When sex,birth history and other factors were controlled in multivariate-logistic regression analysis,there is an increased risk of anemia among local children than local children(OR=1.81,95%CI:1.20-2.72).Children whose mother,s childbearing age is more than 30 years old,compared to whose mother,s childbearing age is 24~29 years old,the risk of IDA is increased.(OR=2.05,95%CI:1.27-3.29).Breast-fed group and Mixed-fed group and are all more at risk for anemia than formula-fed group.(OR=10.22,9.43,95%CI:6.12-17.06.5.93-15.00)IDA is a common nutritional disease in infants.Infants are strongly advocated to breastfeed for at least 4 months,preferably delayed to 6-9 months,and after 4-5 months timely to added iron-rich,high absorption food supplement.The importance of breastfeeding cannot be emphasis on,while ignoring the normal development needs of infants.Strengthen the mission work in the floating population and low-education parents to prevent the IDA and the complications.
