Preventative and promotive interventions are most effective when implemented early, at the individual and community level, to address the social, economic, environmental, and behavioral determinants of health and justice.
The public health approach centers on prevention, protection, and promotion by using evidence-based, population-level strategies. Key principles of the public health approach include addressing social determinants, empowering communities, ensuring health equity, applying proportional measures, and implementing intersectoral, multi-level policies—from primordial prevention to rehabilitation.
