About

There is an urgent need to engineer targeted physical activity interventions that are effective and scalable for obese adolescents and young adults (AYA) with type 2 diabetes (T2D), who often have very low levels of physical activity. The BEAM Trial is a mobile health (mHealth) intervention that uses behavioral economic-informed financial incentives and text messaging to promote physical activity in AYA with T2D and prediabetes.
