Study focus
This study evaluated the feasibility of a mobile health app, Plunde, for promoting lifestyle changes in individuals at risk of Type 2 diabetes. It found significant reductions in body weight and waist circumference among app users.
This study highlights the potential of mobile health applications in managing lifestyle changes for individuals at risk of Type 2 diabetes. The significant reductions in body weight and waist circumference suggest that such interventions could play a crucial role in diabetes prevention strategies, ultimately improving health outcomes and reducing healthcare costs.
Effectiveness of the app remains unclear for some outcomes. Study results may not be generalizable beyond the trial population. No significant changes in self-evaluated functional health status.
