Abstract: Objective To evaluate the physical development of full term low birth weight infants,and analyze the effect of early nutrition on the development of intelligence. Methods The results were analyzed on 110 cases of full term low birth weight infants,who visited doctors from 2013 to 2015 in Xi'an No.4 Hospital and were follow-up to 12 months old as well. Results 1) 110 cases of full term low birth weight infants in the physical growth parameters (weight,length and head circumference) in different periods (born,1 month,3,6,9 months and 12 months of age) were still lower than the same sex did not the 3^rd percentile accounted for between existed significant difference(χ²=304.45,381.08,45.80,all P<0.01);2)The physical development index in different periods less than gay did not the 25^th percentile accounted for the ratio of the difference(χ²=193.06,203.12,110.35,all P<0.01);3)Body weight,still less than the 25^th percentile group in the Gesell assessment,the results were worse than 3 months group that the weight was greater than or equal to the 25^th percentile group,adaptability,fine motor,language in the two groups existed significant differences(χ²=8.071,7.981,9.870,all P<0.05). Conclusions After birth,the physical growth of the full term low birth weight infants shows a tendency to catch up,which is the fastest in 6 months.The nutritional status in 3 months have an effect on the Gesell value in 12 months.Early proper nutrition can help to catch up with the physical body of full term low weight infants,which is conducive to the development of intelligence.
