Abstract
Objective. To determine the effect of body weight (BW), body mass index (BMI) and gestational weight gain (GWG) of pregnant women on newborns' growth, to evaluate their connection and perinatal risks. Methods. BW and BMI were determined at the beginning and end of pregnancy in 400 women, as well as GWG during the pregnancy. BMI was classified in categories: <18.5 decreased, 18.5–24.9 normal, 25–29.9 overweight and >30 obesity, and GWG: <8 kg small, 8–16 kg normal and >16 kg excessive GWG. In estimation of the newborns' body growth, birth weight (BW), body lenght (BL), ponderal index (PI) and centile values (CV) were used. Results. There was a significantly higher occurence of BMI >30 in women 30 years and multiparas. Age and parity did not affect newborns' growth. In 88 (22%) pregnant women with BMI1 >25 there was a significant increase in birth of newborns with BW >4000 g and CV >90. In women with excessive BMI and GWG there was an increased occurence of hypertension in pregnancy. There was an excessive GWG in 111 (27.8%) women, more often connected with increased occurence of newborns with CV >90. There was no significant effect of anthropometric measures on delivery and Apgar score. Conclusion. Nutritive status of the mother and gestational weight gain are important indicators for her health and also fetal growth. Relying on maternal body weight alone in determining fetal growth is unadequate, while physical proportions index helps in more precise determination. Mother's overweight before and during pregnancy has a negative effect on both her and newborn's health and is related with the risk of negative delivery outcome.
