Diet InterventionMore Outside Your Door: a Diet/physical Activity Intervention to Decrease Risk of Obesity in Alaska Native Preschoolers

The preschool age is a crucial period of growth and an optimal time to begin to establish healthy eating and physical activity habits leading to better food and activity choices into adulthood, thereby minimizing risk for obesity-related diseases and decreasing the cardiometabolic disparities in this Indigenous population. More Outside Your Door is a multi-level, randomized, stepped-wedge intervention trial designed to reduce the disparity of childhood obesity in Yup'ik Alaska Native children by increasing the proportion of nutrient-dense traditional and traditional-like foods offered and increasing physical activity, particularly outdoor activities related to traditional Yup'ik subsistence and lifestyle practices. This 5-year intervention trial targeting 3-5 year olds is conducted in partnership with Rural Action Community Action Program Head Start programs in 12 rural Alaskan communities, where each site is assigned annually to a wedge group to receive either a community-altered culturally-tailored 8-month traditional foods and activities curriculum intervention or the standard regional Head Start program intervention.
