RESUMO
Objective To compare the body weight,height,head circumference of premature babies fed by different ways,and to analyze the advantages and disadvantages.Methods 260 premature infants were selected as the research subjects,according to random number table,they were divided into four groups.Group A:premature infant formula feeding,80 cases;Group B:pure breast feeding group,60 cases;Group C:normal full term formula feeding,60 cases;Group D:premature infant formula mixed breast feeding,60 cases.All children were fed at the first 12 to 24h after birth.The body weight,height,head circumference and catch up full term time were evaluation index. Results After correct gestational age 40 weeks,group B children'weight,height,head circumference were higher than other groups,group C was the lowest levels,the difference was statistically significant (F =3.563,P <0.05).Correct gestational age 1,3,6 months later,group A children'weight,height and head circumference index were higher than other feeding group,the level of group D was the second,the lowest level was group C,the differences were statistically significant (F =3.011,2.853,2.779,all P <0.05).In 6 months,group A,38.8% (31 /80),was the fastest one to reach the full term infant,the difference was statistically significant (χ2 =29.149,P <0.05).At other time,the pur-suing number of group A was bigger,but there was no statistically significant difference.Conclusion For premature babies,preterm infant formula milk powder or premature infant formula and milk feeding way is better than that of pure breast feeding and normal full term milk powder,which can guarantee the children's nutrition demand,shorten the time of pursuing full term infant,promote baby's health.
