The purpose of the Centers for Disease Control and Prevention (CDC) Division of Nutrition, Physical Activity, and Obesity (DNPAO) Health Equity Resource Toolkit for State Practitioners Addressing Obesity Disparities is to increase the capacity of state health departments and their partners to work with and through communities to implement effective responses to obesity in populations that are facing health disparities. The Toolkit's primary focus is on how to create policy, systems, and environmental changes that will reduce obesity disparities and achieve health equity. For the purpose of this Toolkit, "policy" refers to procedures or practices that apply to large sectors which can influence complex systems in ways that can improve the health and safety of a population. States are already conducting activities to address obesity across populations. This Toolkit provides guidance on how to supplement and compliment existing efforts. It provides evidence-informed and real-world examples of addressing disparities by illustrating how the concepts presented can be promoted in programs to achieve health equity using three evidence-informed strategies as examples: 1. Increasing access to fruits and vegetables via healthy food retail with a focus on underserved communities. 2. Engaging in physical activity that can be achieved by increased opportunities for walking with a focus on the disabled community, and other subpopulations that face disparities. 3. Decreasing consumption of sugar drinks with an emphasis on access to fresh, potable (clean) water with a particular focus on adolescents and other high consumers. Though the Toolkit utilizes these three strategies as examples, the planning and evaluation process described in the Toolkit can be applied to other evidence-informed strategies to control and prevent obesity. This Toolkit is a unique resource as it is developed at a state level for health departments and practitioners who work with and through communities, rather than solely addressing communities themselves. Its purpose is to inform state programs that seek to address obesity with a focus on health equity. CDC is also currently developing a Health Equity Playbook, which focuses on addressing health disparities from the community perspective and updating the document Promoting Health Equity: A Resource to Help Communities Address Social Determinants of Health. As you plan and evaluate your state obesity a nd health equity programs, these resources may further enrich your understanding of health equity and social determinants of health.
