Latino migrant farmworkers are at great risk of obesity and its concomitant negative health impacts. Obesity interventions for this underserved, minority population are limited. We expanded upon our prior intervention work in childhood obesity to develop a multi-family, behavioral intervention, ADAPT. We conducted three phases in the development of the ADAPT program: Phase 1, a needs assessment, Phase 2, in-depth focus groups with Latino parents, their children, and stakeholders, and Phase 3, a feasibility and acceptability trial to inform program optimization. Acceptability and feasibility of ADAPT promoting healthier eating and physical activity behaviors was found. Each phase of the project led to implementation changes to ADAPT, resulting in greater intervention optimization. Participants reported key facilitators and barriers to our intervention, expressing great interest in participation. They particularly liked our mindfulness session. We are currently examining the feasibility of integrating mindfulness to optimize ADAPT efficacy.
