Abstract
INTRODUCTION: Nearly half of all women gain above gestational weight gain (GWG) recommendations. This study assessed the feasibility and efficacy of a pilot behavioral intervention on GWG and physical activity behaviors. METHODS:Women (n = 45) 14-20 weeks gestation enrolled in a behavioral intervention. Physicians 'prescribed' the intervention to low risk patients. The intervention included self-monitoring, support, and optional walking groups. Process evaluation measures regarding usage and acceptability of study components were obtained. Physical activity was objectively measured at baseline and 35 weeks. The percentage of participants with appropriate GWG was calculated. Control data was obtained from the same clinic where participants were recruited. RESULTS: Overall, the intervention was acceptable to participants; attrition was low (6.7%), weekly contact was high (87%), and self-monitoring was high (Fitbit worn on 82% of intervention weeks; weekly weighing on 81%). Facebook (40% of weeks) and study website use (19%) was low, as was walking group attendance (7% attended a single group). Participants reported a lack of discussions about the study with their physician. Results showed no significant difference between intervention and control participants in the percentage who gained excess weight (p = 0.37). There was a significant decrease in moderate-to-vigorous physical activity in intervention participants (p < 0.0001). DISCUSSION: Continued efforts for promoting physical activity and appropriate GWG are needed. Although acceptable, the intervention was not efficacious. Trainings for, or input from prenatal healthcare providers on how to best encourage and support patients' engagement in healthy behaviors, such as PA, are warranted.
