APHA's Annual Meeting & Exposition is where public health professionals convene, learn, network and engage with peers. With the Annual Meeting, we strengthen the profession of public health, share the latest research and information, promote best practices and advocate for public health issues and policies grounded in research. The environments in which people live, work, learn and play have a tremendous impact on their health. Responsibility for the social determinants of health falls to many nontraditional health partners, such as housing, transportation, education, air quality, parks, criminal justice, energy, and employment agencies. Public health agencies and organizations will need to work with those who are best positioned to create policies (legal and regulatory) and practices that promote healthy communities and environments and secure the many co-benefits that can be attained through healthy public policy.
