Adherence

Enhanced care interventions (physician letter, personalized chart, and registered dietitian counseling) do not significantly improve gestational weight gain outcomes compared to usual care in the aggregate population of women with pregestational obesity.

For pregnant women with obesity, adding intensive lifestyle interventions (dietitian visits, personalized charts, physician letters) to standard care does not significantly improve overall gestational weight gain outcomes compared to standard care alone. However, this lack of benefit is driven by Class I and II obesity patients who do well with standard care; Class III obesity patients specifically benefit from the enhanced intervention.
