不同喂养方式对早产儿近期生长发育的影响

目的探讨不同喂养方式对早产儿近期生长发育的影响。方法将90例早产儿按喂养方式分为奶粉喂养、母乳喂养和混合喂养3组,监测各组出生时、纠正胎龄40周、纠正年龄1月、纠正年龄2月时身长、体质量、头围等指标的变化。结果纠正胎龄40周时,母乳喂养组体质量、身长、头围、体质量增加量、头围增加量、年龄别体质量z评分等指标均大于其余两组,差异有显著性（F=5.110~27.738,P〈0.05）。奶粉喂养组身长增加量小于其余两组,差异有显著性（F=25.311,P〈0.05）。纠正年龄1月时,奶粉喂养组身长增加量大于其余两组,差异有显著性（F=6.518,P〈0.05）;母乳喂养组体质量增加量、头围增加量大于其余两组,差异有显著性（F=8.770、19.482,P〈0.05）。纠正年龄2月时,奶粉喂养组体质量、身长、体质量增加量、头围增加量大于其余两组,差异有显著性（F=4.047~17.044,P〈0.05）;母乳喂养组身长增加量小于其余两组,差异有显著性（F=22.241,P〈0.05）。结论纠正胎龄40周时母乳喂养组生长占优势,此后奶粉喂养组生长占优势。

INFLUENCE OF DIFFERENT FEEDING PATTERNS ON SHORT-TERM GROWTH AND DEVELOPMENT IN PREMATURE INFANTS

ObjectiveTo explore the influence of different feeding patterns on short-term growth and development of premature infants.MethodsAccording to feeding patterns,90 premature infants were divided into three groups as milk-powder feeding,breast feeding and mixed feeding.Changes of body length,body weight and head circumference were recorded at birth,40 weeks,one and two months of correction age.ResultsAt 40 weeks of correction age： in breast feeding group,the increase of body weight,body length,head circumference,and agespecific body weight z score were greater than the other two groups,the differences between them were significant（F=5.110-27.738,P0.05）;the increase of body length in milk-powder feeding group was less than the other two groups,with significant difference between the two groups（F=25.311,P0.05）.At one month of correction age： the increase of body length in milk-powder feeding group was greater than the other two groups（F=6.518,P0.05）;in breast feeding group,the increase of body weight and head circumference was greater than the other two groups（F=8.770,19.482;P0.05）.At two months of correction age： the increase of body length,body weight,and head circumference in milk-powder feeding group was greater than the other two groups（F=4.047-17.044,P0.05,）;the increase of body length in breast feeding group was less than the other two groups（F=22.241,P0.05）.ConclusionAt 40 weeks of correction age,the growth in breast feeding group predominates,after this,the growth in milk-powder feeding group prevails.
