What this trial studies

This research aims to evaluate the effectiveness of a couple-based lifestyle intervention designed to prevent type 2 diabetes among partnered adults at high risk. The intervention focuses on enhancing lifestyle changes through the support of romantic partners, addressing both individual behaviors and the shared environment of couples. The study will recruit 162 couples from community and healthcare settings, assessing the impact of relationship satisfaction and perceived partner support on lifestyle changes. By engaging couples, the study seeks to improve retention rates and health outcomes in populations disproportionately affected by diabetes.
