OBJECTIVE: To determine whether the prescription and follow-up of a behavioral program (customized nutritional advices and a constant physical activity) influences the occurrence of unfavorable maternal/neonatal outcomes among overweight/obese women.
METHODS: A case-control study (1:3) included single pregnant women with BMI≥25, enrolled at 1st trimester. Cases (95) were prescribed (by both the dietitian and gynecologist) a low-glycemic index diet with an average intake of 1700/1800 Kcal/day plus 30 minutes walking at least 3 times/week (with four follow-up visits until delivery). Controls (275) received a nutritional booklet about a healthy lifestyle, than attended their scheduled visits until delivery by the obstetricians in charge.
RESULTS: Gestational weight gain was similar between groups, despite obese women were higher in Cases (67.4%) than in Controls (54.5%, p=0.029). The occurrence of gestational diabetes mellitus (GDM) was lower in Cases (21.5%) than in Controls (32.7%; p=0.041). Such reduction remained related with the group of intervention (p=0.004) after correcting for confounders (BMI≥ 30, a family history of diabetes, age ≥ 35 and ethnicity). A higher number of Controls developed pregnancy induced hypertension (PIH) (11.6% vs 1.1% in cases, p<0.001). Preterm birth (PTB) occurred in one Case and in 28 Controls (10.2%; p=0.004). In the half of them, PTB was spontaneous while medically indicated for Intrauterine Growth Restriction, haemorrhage, PIH, GDM/macrosomia, Rh isoimmunisation in the remnant.
CONCLUSIONS: An early behavioral intervention among overweight/obese pregnant women reduces unfavorable pregnancy outcomes.
