A groundbreaking white paper from the USC Schaeffer Center highlights that broadening access to anti-obesity medications could significantly enhance life expectancy and reduce disease incidence, offering substantial societal benefits. This analysis underscores the importance of viewing these treatments not merely as expenses but as long-term investments in public health. With over 40% of U.S. adults classified as obese—a condition linked to more than 200 diseases—this issue carries an annual societal cost of $260 billion. Despite the availability of highly effective medications, coverage remains limited due to upfront cost concerns.

The study reveals that extending access to all qualifying adults without diabetes would yield a staggering $10 trillion in social value, enabling longer, healthier lives. This investment offers an annual return exceeding 13%, comparable to high-value initiatives like early childhood education. The research emphasizes the lifetime benefits of treatment, preventing or delaying obesity-related complications and improving overall quality of life.

Researchers utilized the Future Adult Model to simulate health trajectories, medical spending, and economic outcomes for adults aged 25 and older without diabetes who qualify for anti-obesity medication. Findings were segmented by age group, BMI, and diabetes risk. Assuming a conservative decline in net prices until generic competition begins in 2032, younger and healthier adults demonstrated the most significant gains, with potential life extensions of up to 1.8 years and additional diabetes-free years reaching 5.9.

While insurers often restrict coverage to sicker patients, the analysis suggests early intervention could prevent more severe and costly outcomes. Co-author Darius Lakdawalla notes that limiting coverage overlooks opportunities for prevention. Remarkably, nearly every analyzed group exhibited positive lifetime net social value, underscoring the broad applicability of expanded access.

Across populations, the internal rate of return (IRR) on expanding access exceeded 13% over three decades, reflecting the profound long-term health and economic benefits. Dana Goldman asserts that this policy represents one of the most effective strategies to enhance public health. The challenge lies in balancing innovation rewards with minimizing public costs.

This transformative approach to addressing obesity not only promises improved health outcomes but also positions society for significant economic advantages. By rethinking how we view and implement access to anti-obesity medications, policymakers have an unprecedented opportunity to revolutionize public health and welfare.
