"Post-Protean" Public Health and the Geroscience Hypothesis

Area of Science:

• Public Health
• Gerontology
• Biomedical Research

Background:

• Life expectancy improvements have stalled in the US despite significant research investment.
• This stagnation is partly due to an over-reliance on the "Protean" public health model, focused on infectious disease.
• The "Protean" model is less effective for enhancing the quality of life for older individuals.

Purpose of the Study:

• To analyze the limitations of the "Protean" public health approach.
• To highlight the potential of the "Post-Protean" public health vision, including the Geroscience Hypothesis.
• To advocate for a shift in public health priorities towards increasing healthspan.

Main Methods:

• Conceptual analysis of historical public health paradigms ("Protean" vs. "Post-Protean").
• Review of the Geroscience Hypothesis and its implications for aging populations.
• Examination of current public health outcomes in relation to life expectancy and healthy life expectancy.

Main Results:

• The "Protean" model, effective against early-life infectious diseases, does not adequately address age-related health issues.
• "Post-Protean" public health, emphasizing indirect health improvement methods and experimental research, offers a more promising approach for aging.
• The Geroscience Hypothesis provides a framework for understanding and intervening in the aging process to improve healthspan.

Conclusions:

• Relaxing the dominance of the "Protean" model is necessary to realize the benefits of "Post-Protean" public health.
• Public health goals should shift from merely extending lifespan to increasing healthspan.
• Managing multi-morbidities and improving the quality of life for older adults requires a new public health paradigm.
