The CDC’s Prevention Status Reports(link is external), evaluates public policies pertinent to 10 health problems faced by every state: excessive alcohol use, food safety, teen pregnancy, health care-associated infections, HIV, prescription drug overdose, heart disease and stroke, motor vehicle injuries, tobacco use, and nutrition, physical activity and obesity. The CDC gives each state a red, yellow, or green rating on each topic, depending on the success of their policies and programs in dealing with that specific issue. Green means that the policy is established in agreement with recommendations or expert recommendations, yellow means that the policy is established with partial accordance, and red means that the policy has not been established.
Pick a state and choose an issue identified as underperforming. Approach that health issue focusing on the elements in the spectrum of prevention: influencing policy and legislation, changing organizational practices, fostering coalitions and networks, educating providers, promoting community education and strengthening individual knowledge and skills. The entire effort culminates in a submission of a comprehensive policy brief.
