Intrauterine growth is due to a number of genetic and environmental factors, and refers to the slowing growth of the fetus whose potential is higher than measured. The purpose of this work is the study of infants whose birth weight was below the 10 percentile values for a given gestational age. Newborn babies are born in the maternity ward of the Clinic for Gynaecology and Obstetrics Hospital Rijeka in 2013. All infants had less than 3000 grams. As a source of data to the maternity Protocol of 2013. The parameters are processed in the work include pregnant women age, parity, pregnancy complications, duration of pregnancy, fetal attitude, gender, weight, length, head circumference, Apgar score at one and five minutes, and the way delivery. Of the total number of live births 8.87% have stunted growth. Born 58% girls and 42% of boys. In the period from 38 to 41 weeks born 60.75% and before 37 weeks 39.25% of children. Complications that occur in pregnancy, placental insufficiency, oligohydramnios, preeclampsia and hypertension affect fetal growth. Intrauterine growth mostly affects birth weight and a higher percentage of children weighing less than 2,500 grams. With lower birth weight and gestational age less increased mortality and morbidity. Complications in infants with intrauterine growth require many hospitalization, and further growth in children can occur motor and neurological damage. The only real treatment is timely completion of delivery. Decision on the due date shall be made on the basis of the maternal and fetal condition.
