Abstract
Conclusion: Women with higher pre-pregnancy BMI and women with excessive weight gain in pregnancy had higher rates of inadequate glycaemic control in the 3rd trimester and of LGA newborns. In all BMI groups, excessive weight gain in pregnancy led to an increased occurrence of LGA. Although maternal prepregnancy BMI is important for the occurrence of LGA, weight gain in pregnancy is also an important factor that can significantly influence fetal overgrowth. This highlights the need, not only to control women’s weight before pregnancy, but also during its course, to reduce the risk of fetal overgrowth. Background and aims: Maternal BMI and weight gain are associated with maternal and fetal complications in gestational diabetes (GD), but their relative contribution is not clearly defined. The aims of this study are, in women with GD, to analyse: 1) the relationship between maternal pre-pregnancy BMI and previous maternal factors; 2) the absolute weight gain and excessive weight gain in pregnancy according maternal BMI ; 3) the influence of maternal pre-pregnancy BMI and maternal excessive weight gain in the evolution of pregnancy and in fetal overgrowth.
