Every Little Step Counts: Efficacy Trial

Every Little Step Counts: Efficacy Trial

Funding: National Institutes of Health/National Institute on Minority Health and Health Disparities, center grant award P20 MD002316 NIMHD (2012-2017)

This study, using a randomized-controlled trial, tests the efficacy of  a culturally-grounded, community-based diabetes prevention program to increase insulin sensitivity and weight-specific quality of life in 160 obese Latino adolescents. The study also explores potential mediators and moderators of the intervention’s effects and estimates the initial incremental cost-effectiveness of the intervention for increasing insulin sensitivity. The intervention is guided by Social Cognitive Theory and framed within a multilevel ecodevelopmental model to address surrounding contextual factors that are thought to influence health behaviors and health outcomes in obese Latino youth during a critical life period. The project builds upon extant collaborations of a transdisciplinary team of investigators with the community to address critical gaps in how prevention interventions for obese Latino youth are developed, implemented and evaluated. This innovative approach is an essential step in the development of cost-effective, solution-oriented programs to improve the health of Latino youth.


  • Enrollment and data collection are complete.
  • Data cleaning and analysis are underway.
  • Additional funding has been secured to adapt and evaluate the intervention for obese Latino youth with prediabetes. (NIH/NIDDK - R01 DK107579)
  • Additional funding has been secured to further refine and test the feasibility, acceptability, and preliminary efficacy among Latino families in Maryvale, AZ. (Az Dept Health Services ADHS16-105121)
