摘要：The goals of the Central California Regional Obesity Prevention Program (CCROPP) are to promote safe places for physical activity, increase access to fresh fruits and vegetables, and support community and youth engagement in local and regional efforts to change nutrition and physical activity environments for obesity prevention. CCROPP has created a community-driven policy and environmental change model for obesity prevention with local and regional elements in low-income, disadvantaged ethnic and rural communities in a climate of poor resources and inadequate infrastructure. Evaluation data collected from 2005–2009 demonstrate that CCROPP has made progress in changing nutrition and physical activity environments by mobilizing community members, engaging and influencing policymakers, and forming organizational partnerships. KEY FINDINGS ▪ CCROPP took a community-driven policy and environmental change approach to obesity prevention, with local and regional components. ▪ CCROPP community partners and public health departments increased access to healthy food and physical activity opportunities through neighborhood engagement, inclusive partnerships, and local policymaking. ▪ Community resident engagement was the central strategy CCROPP used to change food and physical activity environments. ▪ CCROPP sites informed state-level policy, and disseminated their accomplishments and lessons learned through state and national networks. CALIFORNIA'S CENTRAL Valley, one of the nation's leading agricultural regions, is also one of the poorest, where overweight and obesity occur alongside hunger, and where food deserts—places where fresh affordable produce can't be found—abound. 1 The Central California Regional Obesity Prevention Program (CCROPP) involved 8 counties (Fresno, Kings, Kern, Madera, Tulare, Merced, Stanislaus, and San Joaquin) with similar geographic, social, and political characteristics: few dense urban neighborhoods and many isolated small rural towns. The absence of environments that support access to healthy foods and opportunities for physical activity in the Central Valley has led to the emergence of a new type of obesity-prevention initiative that seeks to create environments that create the conditions that support individuals to adopt healthy eating and physical activity patterns.
