Trial ID: NCT05228860


The goal of ADELANTE is to determine whether a multi-level intervention to improve household food insecurity and glycemic control is effective for Latino patients with diabetes. Specifically, ADELANTE aims to 1. determine whether weekly household food delivery plus an intensive lifestyle intervention is more effective than usual care for improving glycemic control (HbA1c) at 6 months, 2. examine the effects of the multi-level intervention on = household food insecurity, dietary behaviors, and psychosocial outcomes, and 3. assess the future potential for implementation and dissemination of this multi-level intervention in primary care settings.
