Clinical Trial Summary

The purpose of the study is to develop a culturally adapted intervention (CAI) program to improve weight and physical activity in overweight or obese adult Latinos at high risk for developing type 2 diabetes and/or cardiovascular disease (CVD) and to rigorously evaluate the effectiveness and implementation potential of the CAI program.


Clinical Trial Description

This study has two phases: Phase 1: Formative research and Phase 2: Randomized Controlled Trial (RCT). The purpose of the formative research phase is to develop a culturally adapted intervention (CAI) program to improve weight and physical activity in overweight or obese adult Latinos at high risk for developing type 2 diabetes and/or cardiovascular disease (CVD). The purpose of the RCT is to rigorously evaluate the effectiveness and implementation potential of the CAI program.

The proposed intervention will uniquely adapt the coach-led, technology-supported Group Lifestyle Balance (GLB) program that the investigators proved effective in the investigators' prior trial called E-LITE, to provide culturally and linguistically appropriate lifestyle intervention for weight loss and increased physical activity among high-risk Latinos in primary care. The CAI will be delivered in small groups as well as using existing, rapidly expanding internet and mobile technologies (Website, email, and mobile text messaging). Once developed the investigators will subject the CAI to rigorous evaluation in an RCT of 186 eligible and consenting Latinos. The investigators hypothesize that CAI participants will achieve a greater mean reduction in body mass index (BMI) from baseline to 24 months (primary outcome) than usual care controls. Secondary outcomes will include measures of cardiometabolic risk factors (e.g., lower fasting glucose and lipid levels), psychosocial well-being (e.g., improved mood), and behavior change (e.g., increased physical activity). The overarching research goal is to determine the effectiveness and implementation potential of the CAI based on the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. ;
