Risk Factors For Anemia In Premature Infants At The Corrected Age Of 6 Months And Its Effects On Neuropsychological Development

Objective: To explore the risk factors for anemia in preterm infants when correcting gestational age at 6 months age,and to study the effects of anemia on neuropsychological development of preterm infants.Methods: A total of 93 preterm infants with a correct gestational age of 6 months who were examined in the Department of Children Healthcare in the First Hospital of Lanzhou University from March to December 2019,were selected as the research subjects.According to the detected hemoglobin value,they were divided into two groups:anemia(n=50),non-anemia(n=43).And design questionnaires,collect relevant clinical data,understand the related factors that affect anemia in preterm infants by univariate analysis of variance and t test,and use binary logistic regression to analyze the risk factors for anemia preterm infants when correcting gestational age at 6 months age.Gesell Development Scale was used to evaluate the neuropsychological development of all subjects,and t-test and person bivariate correlation analysis were used to analyze the effect of anemia on neuropsychological development of premature infants.Results: 1.The smaller the gestational age and the lower the birth weight,the lower the hemoglobin value of premature infants,and statistically significant(P<0.05).2.Gestational age,birth weight,days of hospitalization in the neonatal period,non-infectious respiratory diseases in the neonatal period,and maternal pregnancy illnesses are all related factors of anemia in preterm infants,among which low birth weight and maternal pregnancy illnesses are high risk of anemia in preterm infants,the influencing factors are all statistically significant(P<0.05).3.Corrected gestational age At 6 months of age,the development quotient of the 5 energy zones of the Gesell Development Scale of the anemia group was significantly lower than that of the non-anemic group,the difference was statistically significant(P<0.05).4.Gesell score DQ values of 5 energy zones are all correlated with hemoglobin value,which isstatistically significant(P<0.05),and the correlations are from coarse to fine,fine to fine,adaptive,personal-social,language.Conclusion: 1.Birth weight and avoidance of illness during maternal pregnancy are protective factors for anemia in preterm infants.2.Anemia affects the neuropsychological development of premature infants.
