SUMMARY:

Pre-gestational obesity represents a significant risk factor for the development of Gestational Diabetes Mellitus (GDM), a condition that independently poses severe risks of maternal-fetal complications. However, the influence of pre- gestational obesity on these outcomes in women with GDM remains incompletely understood. Therefore, this study aimed to evaluate the association between pre-gestational obesity and maternal and neonatal outcomes in women diagnosed with GDM. This was a prospective, longitudinal, observational cohort study involving maternal-child dyads diagnosed with GDM. GDM was diagnosed according to the guidelines of the Brazilian Diabetes Society. Women were stratified into two groups based on their pre- gestational BMI: < 30 kg/m2 (non-obese) and ≥ 30 kg/m2 (obese). Data collection occurred at three time points: T1 (second trimester), T2 (third trimester), and T3 (immediate postpartum). Collected data included sociodemographic, clinical, and anthropometric characteristics, glycemic control parameters, as well as postpartum perinatal outcomes. Glycemic control was evaluated through capillary blood glucose measurements at fasting, post-breakfast, post-lunch, and post-dinner across all three time points. Gestational weight gain (GWG), presence of anemia, blood pressure alterations, treatment type (dietary management or insulin therapy), and maternal complications were also analyzed. Regarding neonatal outcomes, associations between pre-gestational obesity and the incidence of neonatal hypoglycemia, breastfeeding within the first hour of life, neonatal complications, and intrauterine growth were evaluated. A total of 164 women (53.7% with pre- gestational obesity and 46.3% without) and their neonates were included. Women with obesity demonstrated higher educational attainment, lower income, higher parity, and lower gestational weight gain across all three evaluated periods (p < 0.001). Additionally, pre-gestational obesity was associated with a higher rate of insulin therapy requirement (46.6% vs. 30.3%; p = 0.033). No statistically significant differences were observed regarding mean capillary blood glucose levels throughout pregnancy or in neonatal outcomes. These partial findings suggest that pre-pregnancy obesity impacts GDM management and gestational weight gain, even when patients are followed by a specialized multidisciplinary care service.
