International Gains to Achieving Healthy Longevity

Area of Science:

• Health Economics
• Gerontology
• Public Health Policy

Background:

• The relationship between biological and chronological age significantly impacts individual health and longevity.
• Aging processes present complex challenges across multiple diseases and health outcomes.
• Economic valuation of health interventions is crucial for policy development.

Purpose of the Study:

• To quantify the economic gains associated with improving the alignment of biological and chronological age.
• To assess the impact of targeting aging on health, life expectancy, and overall welfare.
• To estimate the financial benefits of slowing the aging process globally and nationally.

Main Methods:

• Economic modeling to evaluate the dollar value of improved age-related health.
• Analysis of synergies between health improvements and life expectancy.
• Cross-disease complementarity assessment in aging interventions.
• Calculation of GDP benefits from increased life expectancy.

Main Results:

• Substantial economic gains for individuals by targeting aging, exploiting health and life expectancy synergies.
• Improvements in life expectancy and an increasing older population significantly boost these gains.
• An estimated annual benefit of 4%-5% of GDP for each year increase in life expectancy.
• The United States shows a particularly acute need for healthy longevity initiatives.

Conclusions:

• Improving the biological-chronological age relationship yields significant economic advantages.
• Healthy longevity is increasingly vital for enhancing societal welfare and economic productivity.
• Policy interventions aimed at slowing aging are essential, especially in developed nations like the US.
