Comparing Levels of Prevention and Service Provision Across the Lifespan.
The four levels of prevention primordial, primary, secondary, and tertiary serve as a foundational framework in public health to mitigate disease onset and progression. These levels align closely with the continuum of healthcare service provision across the lifespan, from early childhood to older adulthood, ensuring that interventions are tailored to developmental and health needs at each stage.

Lifespan Prevention Strategies
Primordial prevention focuses on preventing the emergence of risk factors by addressing social and environmental determinants of health. This level is particularly relevant in early life stages, where policies promoting healthy behaviors, such as access to nutritious food and safe environments, are critical. For example, integrated care models that incorporate early childhood education, housing, and nutrition services exemplify primordial prevention in action (Gonzalez-Bautista et al., 2025).
Primary prevention aims to avert the onset of disease through health promotion and specific protective measures. Vaccination programs, health education, and lifestyle interventions fall under this category. These services are typically delivered through primary care settings and are essential across all age groups. In older adults, primary prevention may include fall prevention programs and screenings for hypertension or diabetes (Bayly et al., 2021).

Secondary prevention involves early detection and prompt intervention to halt disease progression. Screening programs for cancer, mental health assessments, and early treatment of chronic conditions are examples. These services are often integrated into routine care across the lifespan, with age-specific adaptations. For instance, mental health screenings in adolescents and mammography in middle-aged women exemplify secondary prevention tailored to life-stage needs (Stephan et al., 2025).
Tertiary prevention focuses on managing established diseases to prevent complications and improve quality of life. Rehabilitation services, chronic disease management, and palliative care are central to this level. These services are particularly vital in older populations, where multimorbidity and functional decline are prevalent. Effective tertiary care models emphasize interdisciplinary collaboration and patient-centered approaches to optimize outcomes (Bayly et al., 2021).
Service provision across the lifespan must be dynamic and responsive to changing health needs. A life-course approach integrates these levels of prevention into a cohesive system that supports individuals from birth to the end of life. For example, the Pan American Health Organization advocates for integrated, person-centered care models that align preventive strategies with developmental stages and social contexts (Gonzalez-Bautista et al., 2025). However, disparities in access to essential services, particularly in rural and underserved areas, persist as a barrier to equitable prevention and care (Wood et al., 2025).

In conclusion, aligning the four levels of prevention with service provision across the lifespan enhances the effectiveness of public health interventions. A coordinated, life-course approach ensures that individuals receive appropriate preventive and therapeutic services at every stage, ultimately improving population health outcomes and reducing health disparities.
