| Abstract: | This study, carried out on mother-infant pairs in obstetric hospitals in Istanbul, was designed to investigate the impact of some maternal parameters on pregnancy outcome as well as to provide information on birth weight, and incidence of low birth weight, preterm birth, and small for gestational age birth. Low birth weight, preterm birth, and fetal malnutrition are among major risk factors influencing perinatal, neonatal, and postneonatal mortality and morbidity. Reported values for prepregnancy body weight and postpartum measurements of stature, weight, mid-upper arm circumference showed that the women in this series did not have caloric undernutrition, while nearly 9% were of low stature. Maternal stature, postpartum body weight, and postpartum weight and height values were found to be important determinants of birth weight. The frequency of preterm births in this series corresponds fairly well with that found in another group of Turkish mother-infant pairs in which gestational age was determined by Dubowitz scoring. In agreement with many previous studies, maternal stature and body weight stood out as important influences on the outcome of pregnancy in this series. Overall, the nutritional state of the mother prior to pregnancy is the most important determinant of birth weight. |
