Fetal macrosomia is commonly associated with gestational diabetes mellitus (GDM) which may lead to various complications. We attended to establish maternal constitutional and metabolic risk factors responsible for the genesis of macrosomia. 219 GDM mothers were divided into two groups treated by diet or insulin. This study shows that maternal glycemic status and maternal nutritional status before pregnancy are important determinants of fetal macrosomia.

Fetal growth is affected by various maternal factors. Metabolic disturbances often present in pregnancy complicated by insulin-dependent diabetes mellitus may have important effect on birthweight. The aim of this study was to evaluate the influence of maternal morphometric and metabolic factors on birthweight parameters in women with IDDM. Data were analyzed from 124 diabetic women who delivered in I Department of Obstetrics and Gynaecology University Medical School in Warsaw between 1989-1998. Maternal morphometric factors, glycemic control, insulin requirement, glycosylated hemoglobin and fructosamine levels were correlated with birthweight and birthweight ratios. Glycemic control in first weeks of second part of pregnancy as well as maternal height and weight gain during pregnancy affected birthweight in women with insulin-dependent diabetes mellitus.

Various maternal genetic, morphometric and environmental factors may have important effect on birth weight. The aim of this study was to evaluate the influence of maternal pregravid weight, height, body mass index, weight gain during gestation and the length of fenoterol therapy on birth weight in case of imminent preterm labor. The study was performed in the group of 148 pregnant women who delivered after 36th week of gestation as a result of successful tocolytic treatment. Analyzed parameters were correlated with birth weight index and birth weight ratio, also in relation to parity. It was established that birth weight was significantly correlated with maternal morphometric factors but not with fenoterol therapy.
