PROJECT ABSTRACT Sugar-sweetened beverage (SSB) consumption in early childhood has profound implications on future health risks into adulthood. Family-based strategies have demonstrated effectiveness in reducing chronic health risk among children, yet few family-based interventions have specifically targeted healthy beverage consumption. This study advances a long-term goal of developing scalable, multi-level interventions to promote intergenerational health among indigenous families. Using community-based participatory methods and an indigenous conceptual framework – the Navajo Wellness Model – we will conduct a cluster randomized trial to study the effectiveness of Water is K’é, an innovative multi-level intervention designed to promote healthy beverage consumption through strengthened connections with Navajo culture, health information and access to reliable drinking water. Early child education sites will be randomly assigned to immediate or delayed intervention. Children enrolled in the programs, their primary caregiver and other family members will be enrolled and followed for 12 months to assess beverage consumption, health outcomes, as well as family cohesion and cultural continuity. Using a mixed methods design, we will explore how intergenerational family dynamics influence the way in which Water is K’é shapes family health and wellbeing. Finally, we will build greater research capacity in among Navajo partners through Community Advisory Group guidance and leadership, as well as mentorship of tribal college students interested in community research.
