Objective To evaluate the physical growth retardation of premature infants and analyze the possible influencing factors. Methods The results were analyzed on 183 cases of premature infants meeting the selecting conditions,who visited doctors from March 2012 to July 2014 in Xi'an NO.4 Hospital and were followed-up to 1 year old as well. Results 1) By analyzing the weight,length and head circumference,the ratios of growth retardation at birth were respectively 21.3%,15.3%,18.03%,the ratios of the extra uterine growth retardation (EUGR) were 21.9%,11.48%,16.39% for corrected 40 weeks;9.8%,4.92%,3.28% for 3 months;8.7%,4.37%,4.92% for 6 months;8.7%,2.73%,4.92% for 9 months;8.2%,3.83%,3.83% for 12 months.The differences of the ratio of the growth retardation were statistically significant compared with different stages.2) By analyzing the weight,length and head circumference of 6 months,the intrauterine growth retardation (IUGR),birth weight,feeding way and the length of days were risky factors of growth retardation.However,gestational age was not the risky factor. Conclusions The most effective interventive time period should be corrected gestational age within the first 3 months.To strengthen the prenatal care and reduce the incidence of intrauterine growth retardation and extremely low birth weight,shorten the hospitalizate days is the key to prevent the extrauterine growth retardation.
