Study focus
This study evaluated the effects of a health coach-led lifestyle intervention on dietary behaviors in rural adults with type 2 diabetes and prediabetes, finding improvements in dietary self-efficacy and intake.
Improving dietary habits is crucial for managing type 2 diabetes and prediabetes, particularly in rural populations who may face unique challenges. This study highlights the potential of community-based interventions led by health coaches to enhance dietary behaviors, which can lead to better health outcomes and empower individuals in their diabetes management.
Limited generalizability due to the rural population focus Unclear effectiveness for some outcomes No significant change in HbA1c levels
