Nutritional status before pregnancy, blood glucose and maternal body size in pregnancy, and the anthropometry of newborns – preliminary insights from the cribs study

The main goal of this study was to test the association of pre-pregnancy body mass index (BMI) and fasting glucose level in pregnancy on birth size of newborns. The sample consisted of 177 healthy pregnant woman and their newborns from the islands (Hvar and Brač) and the mainland (Split- Dalmatian County) who are participants in the Croatian Islands Birth cohort Study (CRIBS). Anthropometric variables (body weight, height and waist circumference) were measured according to the International Biological Program. Peripheral blood of pregnant women was taken between 22nd and 26th week of gestation, and fasting glucose values >5.1 mmol/L were considered elevated. Statistical analyses were done by SPSS10.0 for Windows. There was a significant positive correlation between pre-pregnancy BMI and fasting glucose levels during pregnancy as well as between pre- pregnancy BMI and birth weight, length, and head circumference of the newborns. Hyperglycemic women gave birth to significantly heavier newborn girls then normoglycemic women (p<0.05). There was a positive correlation between pre- pregnancy BMI, fasting glucose during pregnancy and the anthropometry of newborns.
