Adaptive Mobile Health Intervention to Reduce Excess Gestational Weight Gain

Does standard care plus an evidence-based, adaptive mobile health lifestyle intervention reduce excessive gestational weight gain (GWG) for patients with overweight or obesity compared with standard care alone?In this cluster-randomized trial including 58 randomized clinicians treating 1265 enrolled pregnant patients, compared with standard care, the intervention significantly lowered the weekly rate of GWG and total GWG. Fewer patients in the intervention group than in the standard care group exceeded the national guidelines for weekly rate of GWG and for total GWG.This cluster-randomized clinical trial demonstrated that an evidence-based, mobile health lifestyle intervention modestly reduced total GWG and weekly rate of GWG among patients with overweight or obesity.
