Living Longer, Yet Less Healthy: Insights from a Global Study
Recent studies reveal that while life expectancy is increasing, people are spending more years in suboptimal health.
The fundamental promise of modern medicine has been to extend lifespan. However, a newly published international study brings to light a troubling paradox—we are living longer, but much of that time is spent grappling with severe health challenges.
Emerging Global Health Disparities
As reported in the study published in JAMA Network Open on Wednesday, women are disproportionately affected by this health gap, experiencing an average of 2.4 more years of compromised health compared to men.
The authors of the study noted, “A sex disparity in the healthspan-lifespan gap was identified here at global scale,” highlighting the impact of longer life expectancy in women coupled with a significant burden of noncommunicable diseases.
In the United States, the gap between health span and lifespan is most stark, with Americans reporting 12.4 years of compromised health. This disparity is largely fueled by the rising prevalence of noncommunicable diseases, such as diabetes and heart disease.
Urgent Action Needed to Tackle Chronic Diseases
Over the last 20 years, global life expectancy has increased by more than six years, yet health-adjusted life expectancy—which reflects quality of life—has risen by only 5.4 years, as per the study’s findings.
This discrepancy underscores an urgent need to enhance health management and address chronic illnesses that compromise life quality, the researchers emphasized.

Additionally, the economic repercussions could be significant, including higher healthcare expenditures due to chronic illnesses, lower workforce participation, and increased pressure on social security and Medicare systems.
In the U.S., mental health conditions and musculoskeletal disorders, such as arthritis and osteoporosis that impact the muscles, bones, and connective tissues, are major factors contributing to this gap.
The researchers highlighted the necessity of focusing not only on longevity but also on improving quality of life. They called for policies and initiatives that prioritize health and well-being in light of an aging global population, aiming to reduce the disparity between health span and lifespan.
