Introduction: The present study aimed to investigate whether women who developed gestational diabetes mellitus (GDM) comply with the guidelines for gestational weight gain (GWG) according to their pre-pregnancy Body Mass Index (BMI).
Methods: A retrospective study was conducted involving 195 pregnant women with GDM, aged 2545 years, attending an academic hospital outpatient clinic. These women were divided into three groups according to pre-pregnancy BMI (underweight, optimal, overweight).
Results: The mean GWG was 9.9±6.3 kg; in 28% of cases, GWG was higher than suggested by the Institute of Medicine (IOM) guidelines. The three groups differed in GWG (underweight: 5.5±5.1 vs optimal: 10.9±2.7 vs overweight: 16±5.4 kg, P<0.001), with those being underweight gaining less, and those being overweight gaining more than suggested by IOM. Fetal weight in the optimal and overweight groups was higher compared with the low weight group (underweight: 2990±456 vs optimal: 3146±467 vs overweight 3201±650 g, P=0.089).
Conclusion: GWG in women with GDM depends on the pre-pregnancy weight. A better compliance of women to the guidelines is advisable, to avoid pregnancy complications.
