Background: Interventions to prevent excessive gestational weight gain (GWG) have had limited success This pilot study examined the effectiveness of a single goal (SG) high dietary fiber intervention to prevent excessive GWG.
Methods: Twelve weekly lessons focused on consuming a high fiber diet (≥30 g/day). Snacks containing 10-12 g of dietary fiber were given for the first six weeks only. Body composition was measured at baseline and at the end of the intervention. At one-year postpartum, body weight retention and dietary practices were assessed. A p-value is reported for the primary analysis only. For all other comparisons, Cohen’s d is reported to indicate effect size.
Results: The SG group increased fiber intake during the study (32 g/day at 6 weeks, 27 g/day at 12 weeks), whereas the UC group did not (~17 g/day). No differences were found for the proportion of women classified as excessive gainers (p=0.13). During the intervention, the SG group gained less body weight (-4.1 kg) and less fat mass (-2.8 kg) (d=1.3). At one year postpartum, the SG group retained less weight (0.35 vs. 4.4 kg, respectively; d=1.8), and reported trying to currently eat high fiber foods.
Conclusion: The SG intervention resulted in less weight gain, fat accrual, and weight retention at one year postpartum. A residual intervention effect was detected postpartum with the participants reporting continued efforts to consume a high fiber diet.
