NCT03113916

Brief Summary

This pragmatic randomized clinical trial will assess the efficacy, cost, and sustainability of a culturally tailored weight-loss program targeting obese Hispanic women with pre-diabetes or T2D. The intervention will be integrated into patient care at a Federally Qualified Health Center serving over 30,000 low-income patients, and will be delivered by trained clinic staff, with minimal support from research staff. After the effectiveness clinical trial, two cohorts of clinic patients will receive the intervention in a sustainability test.
