Sharing your newfound knowledge will allow a network to grow and ultimately spark a grassroots movement to alleviate health disparities.
Participating in community service is the most direct and effective way of promoting health in your community.
Write letters and reach out to your elected officials and see if they are aware actively supporting initiatives that promote community health. Suggest some issues for your elected official to look into or question the effectiveness of a current policy. The constituency is best at not only identifying community problems, but for resolving them as well!
