The Equitable Healthy Aging in Public Health Toolkit provides local health departments with guidance on advancing equitable healthy aging in community health improvement practice. The toolkit includes modules on foundational principles such as social justice, social determinants of health and intersectionality across the life course, age-friendly public health frameworks, and evidence-based actions to advance equitable healthy aging in community health improvement infrastructure, assessment, implementation planning, and practice. The toolkit is based on contemporaneous public health knowledge and practice on healthy aging and health equity along with advisory input from the Trust for America's Health and the National Association of City and County Health Officials. The toolkit was informed by Florida Department of Health practitioners (n = 79) and further vetted and well received with a statewide master class of public health leaders (n = 29). The toolkit is publicly available and free of charge.
