85例早产儿早期追赶生长影响因素分析
Influencing factors of physical catch-up growth of 85 preterm infants during infancy
摘要
Abstract
Objective To analyze the influencing factors of physical catch-up growth of preterm infants during infancy including weight, length and head circumference, so as to provide reference for physical evaluation and clinical intervention.Methods Eighty-five preterm infants in the management of Changsha Hospital for Maternal and Child Health Care and followed up regularly in the first 12 months after birth were selected in the study, and they who were divided into early preterm group ( 40 cases ) and late preterm group ( 45 cases ) according to gestational weeks at birth.The standard deviation of the difference method ( Z-score) was used to evaluate weight, length and head circumference.The characteristics of catch-up growth during infancy of these 85 premature infants were analyzed.The ratio of growth retardation ( GR) and the increase in Z values (△Z) were compared between two groups in different age periods.Furthermore, the related factors of GR for weight at 12 month were analyzed.Results The percentages of neonates with △Z<-2 in weight, length and head circumference were 88.2%(75/85), 88.2%(75/85) and 91.7%(78/85), respectively at birth, and they were 9.4%(8/85),4.7%(4/85) and 2.3%(2/85), respectively at the age of 12 months.In two groups the△Z values of weight, length and head circumference were more than 0.5 under the age of six months, while they were less than 0.3 after six months of age.The△Z values of weight, length and head circumference in late preterm group were significantly more than those of early preterm group at the first month ( t value was 7. 70, 6.12 and 5.52, respectively, all P<0.05), but there was no statistical significance in the difference of△Z values at other months of age.The incidence of intrauterine growth retardation ( IUGR) was higher in the GR infants at 12 month of age than that in normal growth infants (χ2 =4.50,P <0.05), but nutrition fortifying rate and early family touch rate were lower (χ2 value was 7.07 and 4.66, respectively, both P<0.05).Conclusion The best time of catch-up growth for preterm infants is the first year after birth, and the catch-up growth in weight, length and head circumference is featured by growing fast at first and slowing down later.Nutrition fortifying at birth and receiving early touch in family can promote catch-up growth in preterm infants.关键词
