SPARK: Smartphone App to Support Lifestyle and Blood Sugar Control in Gestational Diabetes Patients

What this Trial Is About

Gestational diabetes mellitus (GDM) is a growing public health concern that requires effective and scalable lifestyle support for affected women to manage their condition and reduce risks for both mother and baby. This project aims to evaluate a new mobile health platform called SPARK, which is designed to help women with GDM improve self-management and prevent negative obstetric and neonatal outcomes. The study is a multi-center randomized controlled trial recruiting women with GDM in South Eastern Sweden. Participants will all receive standard care for GDM. In addition, those in the intervention group will use the SPARK digital platform, which supports healthy eating, physical activity, and glucose control. The platform includes an app for patients and a caregiver interface that allows healthcare providers to monitor blood glucose levels and provide feedback. The study will focus on outcomes measured at gestational weeks 36-37, including blood glucose control, HbA1c levels, diet, physical activity, and metabolic and inflammatory biomarkers. During the study, researchers will assess pregnancy outcomes as well as adverse obstetric and neonatal events. Secondary outcomes include cardiometabolic risk factors and behaviors related to physical activity and healthy eating one year after delivery. Participants will be monitored through the platform and clinical assessments to measure these outcomes and support ongoing management of GDM.
