Objectives: Excess gestational weight gain is associated with increased risk of poor nutrition-related outcomes in infants. This study investigated the Goals for Reaching Optimal Wellness (GROWell) RCT on breastfeeding practices.

Methods: The GROWell trial tested an mHealth dietary intervention beginning prenatally (approximately 15 weeks) to achieve appropriate gestational weight gain and postpartum weight loss in pregnant women who were overweight/obese in California. The intervention group received personalized, goal-oriented text messages regarding dietary choices, while the attention control group received text messages about healthy pregnancy, labor, delivery, and early infancy. Surveys were administered at baseline, 3 and 6 months postpartum (n=454). Labor and delivery data is being collected from medical record abstraction (current n=50). Baseline diet quality was captured using the Rapid Eating Assessment for Participants questionnaire (range Healthy Eating Index Score=24-72), and physical activity was assessed using the Pregnancy Physical Activity Questionnaire (range 0-800 MET). To assess the unadjusted and covariate adjusted effect of the intervention, logistic regression was used for binary outcomes.

Results: Mean (SD) age of mothers was 33.7 (4.1) years and 70% were college educated. Baseline diet quality score was 52.9 (6.3) and physical activity score was 125.6 (76.4). Breastfeeding practices did not differ between groups: breastfeeding initiation (intervention=92.4%, control=89.2%, P=0.37), breastfeeding exclusivity at 3 months (intervention=71.0%, control=69.9%; P=0.94) and at 6 months (intervention=47.7%, control=40.1%, P=0.29). Results were similar in adjusted models.

Conclusions: A mHealth dietary intervention administered to pregnant women did not impact breastfeeding outcomes. Designing mHealth dietary interventions focused on both the mother and infant may be more effective at improving nutrition across the lifespan.
