The document outlines Lalonde's conceptual framework for subdividing health into its principal determinants: human biology, environment, lifestyle, and health care organization. Human biology includes physical and mental aspects that develop from human genetics. Environment refers to external factors like air, water, and soil quality that individuals have little control over. Lifestyle consists of personal decisions and habits that impact health. Health care organization is the structure, resources, and relationships within the medical system.
