Study focus
This study evaluated the effectiveness of a mHealth voice messaging intervention for preventing and controlling type 2 diabetes mellitus (T2DM) in rural Bangladesh, finding improvements in knowledge but no impact on T2DM occurrence.
Understanding the effectiveness of mHealth interventions is crucial for public health strategies, especially in rural areas where access to healthcare is limited. This study highlights the potential of technology to enhance knowledge about diabetes, but also points to the challenges in sustaining engagement and achieving health outcomes.
Limited engagement due to technological faults. High frequency of mobile phone number changes among participants. Message fatigue affected participant retention.
