Obesity Clinical Trial - Preventing Diabetes in Latino Youth

Status Completed

Clinical Trial Summary

Obesity and type 2 diabetes are critical public health issues in youth. This study will test the effects and estimate the cost-effectiveness of a culturally-grounded community-based lifestyle intervention on type 2 diabetes risk among obese Latino adolescents with prediabetes.

Clinical Trial Description

Obesity and related health disparities represent some of the most significant public health challenges facing society. In particular, obese Latino adolescents are disproportionately impacted by insulin resistance and type 2 diabetes. Prediabetes is an intermediate stage in the pathogenesis of type 2 diabetes and represents a critical opportunity for intervention. The Diabetes Prevention Program established that lifestyle intervention can prevent or delay type 2 diabetes in adults with prediabetes. To date, no diabetes prevention studies have been conducted in obese Latino youth with prediabetes, a highly vulnerable and underserved group. Therefore, investigators propose a randomized-controlled trial to test the short-term (6-month) and long-term (12-month) efficacy of a culturally-grounded, lifestyle intervention, as compared to usual care, for improving glucose tolerance and reducing diabetes risk in 120 obese Latino adolescents with prediabetes. Investigators will further test intervention effects on changes in quality of life, explore the potential mediating effects of changes in total, regional, and organ fat on improving glucose tolerance and increasing insulin sensitivity, and estimate the initial incremental cost-effectiveness of the intervention as compared with usual care for improving glucose tolerance. The overall approach is framed within a multilevel Ecodevelopmental model that leverages community, family, peer, and individual factors during the critical transition period of adolescence when changes in health behaviors and health outcomes are linked to future health trajectories. The intervention is guided by Social Cognitive Theory and employs key behavioral modification strategies to enhance self-efficacy and foster social support for making and sustaining healthy behavior changes. The proposal builds upon extant collaborations of a transdisciplinary team of investigators working in concert with local community agencies to address critical gaps in how diabetes prevention interventions for obese Latino youth are developed, implemented and evaluated. This innovative approach is an essential step in the development of scalable, cost-effective, solution-oriented programs to prevent type 2 diabetes in this and other populations of high-risk youth. ;

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.
