U.S. Leads World with 14-Year Morbidity Gap, Study Finds

An analysis released in The Lancet Public Health identifies the United States as having the highest morbidity gap on the planet, with citizens spending an average of 14 years of their lives battling disease or disability as of 2023. This figure surpasses the gaps recorded in Australia (13.9 years) and Canada (13.7 years).

While global life expectancy climbed from 64.6 years in 1990 to 73.8 years in 2023, healthy life expectancy rose more modestly from 55.9 to 63.1 years. The nine‑year rise in total lifespan is therefore offset by a smaller seven‑year increase in years lived without major health problems, deepening the disparity.

Dr. Christopher J.L. of the Institute for Health Metrics and Evaluation stresses that health systems must evolve beyond merely extending life. Priorities should include robust disease‑prevention strategies, enhanced long‑term care services, and effective chronic disease management to shrink the morbidity gap.

Gender analysis shows that women, although living longer than men in every region, endure a larger morbidity gap—12.1 years compared with 9.3 years for men. Senior author Catherine Bisignano notes that early action on the conditions that generate long‑lasting health issues for women is crucial.

Musculoskeletal problems, particularly lower‑back pain, dominate the list of health issues driving the global morbidity gap. Mental health concerns such as depression and anxiety, hearing loss due to aging, injuries from falls, and other non‑communicable diseases follow closely behind.

The study also spotlights preventable risk factors: elevated blood sugar, rising obesity, tobacco use, and malnutrition among children and pregnant women. Addressing these lifestyle elements could substantially reduce the years people spend in ill health.

Overall, the findings call for a renewed focus on health quality, suggesting that the world must aim for longer, healthier lives rather than simply longer lives.
