Abstract
PURPOSE: Excessive gestational weight gain is associated with detrimental outcomes to both the mother and baby. Currently, the best approach to prevent excessive gestational weight gain in overweight and obese women is undetermined. The present study aimed to evaluate the effectiveness of a group-based outpatient dietary intervention in pregnancy to reduce excessive gestational weight gain. METHODS: In this retrospective study, overweight and obese pregnant women who attended a single 90-min group education session were compared to women who received standard care alone. Total gestational weight gain, maternal and neonatal outcomes were compared between the intervention and control groups. Data were analysed using Student t, Mann-Whitney and Chi-squared tests as appropriate. A 24-h dietary recall was analysed and compared to the Australian National Nutrition Survey. RESULTS: A significant reduction in gestational weight gain was observed with this intervention (P = 0.010), as well as in the rate of small for gestational age births (P = 0.043). Those who attended the intervention had saturated fat and sodium intake levels that exceeded recommendations. Intake of pregnancy-specific micronutrients including folate, calcium and iron were poor from diet alone. CONCLUSIONS: A low-intensity antenatal dietary intervention may be effective in reducing excessive gestational weight gain, although multi-disciplinary interventions yield the best success. Further research is required to identify the optimal modality and frequency to limit excessive gestational weight gain. Dietary interventions tailored to ethnicity should also be explored. LEVEL OF EVIDENCE: Level II, controlled trial without randomization.
