Evaluation of the Growth of full term Kermanian neonates in the first month of life

The aim of this study was to determine the physical growth of healthy full-term neonates during the first month of life. for this porpuse ۷۸۹ Kermanian healthy full-term singeltone infants were prospectively studied at birth,on the ۱۰th and the ۳۰th day of life for increase in weight(WT),crown heel lenght (CHL),head circumference(HC),chest circumference(CC), and mid arm circumference(MAC).at birth male babies had statistically significant higher values than female for Wt,CHL,HC, (p<۰.۰۰۱).duringg the first ۱۰ days of life the mean (SD) gains in Wt,CHL,HC,CC and MAC were.۱۶۶.۶(۱۳۷.۷) gr ۰.۹(۰.۷),۰.۷(۰.۳),۰.۸(۰.۶) and ۰.۲(۰.۴) centimeter respectively.۹.۹%   of neonates showed weight reduction this period.on the ۳۰ th day of life the mean (SD) gain in weight was ۷۳۶.۶(۲۶۴) gr and the mean (SD) increase in CHL,HC,CC, and MAC were ۳.۱(۱.۳),۲.۴(۰.۹),۳.۱(۱.۲) and ۱.۳(۰.۶) centimeter respectively.there was a significant association (p<۰.۰۰۱) between breast feeding and weight gain during the first ۱۰ days of life.the study showed a significant correlation(p<۰.۰۰۱) between CHL,CC,HC and birthweight.the maximum correlation for CC was (r=۰.۷۷),CHL(r=۰.۷۳) and HC(r=۰.۷۰).multiple stepwise regression analysis showed a significant positive influence of gestational age,gender,maternal age,body mass index(BMI),type of delivery,and breast feeding on some of the anthropometric parameters on the ۱۰th and/or the ۳۰th day of life.percentiles of all anthropometric indices were compared with NCHS standards.the percentiles of Kermanian neonates have lower values than NCHS standards and this suggest,the need for developing national growth reference standards.
