Culturally-adapted Diabetes Prevention Lifestyle Intervention for Latinos

Status Completed

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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
