Title: Healthy Children, Strong Families: American Indian Communities Preventing Obesity
Brief Summary: Healthy Children, Strong Families-2 (HCSF-2) is a family focused early childhood intervention which addresses the growing problem of childhood obesity in American Indian communities. The study works with six rural and urban American Indian communities across the US to test the ability of the intervention to increase adoption of healthy lifestyles and to reduce the prevalence of obesity among preschool aged American Indian children and their primary caregivers - creating healthier children, healthier families and healthier communities. Our primary hypothesis is that children and their primary caregivers who receive the HCSF-2 intervention will have better obesity related outcomes than those who do not receive HCSF-2.
