Background Women with a history of gestational diabetes mellitus (GDM) are at an increased risk developing type 2 (T2DM). Lifestyle interventions aimed postpartum weight loss to reduce T2DM have been reported, but poor compliance remains barrier. Smartphone-based may improve compliance, data on its use in women recent GDM limited. Objective This trial investigate the efficacy smartphone app restoring optimal following delivery GDM, setting population high rates and diabetes. Methods In this unblinded randomized controlled trial, 200 were receive intervention or standard care delivery. The enabled logging weight, meals, activity, web-based interaction team comprising dieticians, physiotherapist, occupational therapist. primary outcome was achievement (defined as restoration first trimester if BMI≤23 kg/m2 least 5% from BMI>23 kg/m2) 4 months post partum. Secondary measures included absolute loss, serum metabolic markers, self-reported nutritional intake, health education, quality life via questionnaires user engagement group. Results total, 40% (38/96) group achieved compared 32% (28/93) control (P=.27). Compared group, reported significantly reduced caloric intake after (P<.001) higher health-directed behavior scores (P=.045). also emotional distress (P=.01). At months, participant maintained 60.8% (SD 33.9%). Conclusions Although statistically significant increase achieving healthy not observed, promising, improved behaviors lower intake. Importantly, retention suggest that larger study longer follow-up period might confirm effectiveness for management.
