Enabling the improvement of people’s health depends both on people taking control of their health as they age to the extent they can and on systems that support healthy choices and provide everyone with affordable, high-quality care. To start, people should have access to care throughout the course of their lives, without regard to their health status, wealth, or location.
Further, while personal behaviors may affect longevity and disability, they are not the only determinants of healthy living and aging. A strong public health system with well-funded programs and activities is important for fostering positive health outcomes for all members of a community. Access to affordable, high-quality clinical preventive services and medical care is critical. Other factors outside the medical system also affect health and longevity. For instance, access to employment, education, housing, healthy foods, safe streets and neighborhoods, and other social supports promote health and reduce health disparities across the population. In addition, environmental conditions, cultural norms, and the historical legacy of discriminatory private- and public-sector practices also play a role in determining health outcomes. Policies and interventions aimed at improving health must address both personal behaviors and systemic factors.
