What is the Origin of Lifespan Gap?

This phrase is a translational term derived from epidemiological and gerontological studies that analyze mortality and morbidity data across populations. It conceptually stems from the comparison of average life expectancy with the theoretical maximum human lifespan, which is thought to be around 120 years. The term 'gap' emphasizes the potential for improvement through targeted health interventions.

What is the Mechanism of Lifespan Gap?

The existence of a lifespan gap is driven by the cumulative burden of chronic, age-related diseases, which are fundamentally rooted in physiological decline and dysregulated homeostatic mechanisms. Key biological mechanisms contributing to the gap include telomere attrition, mitochondrial dysfunction, cellular senescence, and chronic low-grade inflammation, all of which are significantly influenced by hormonal imbalances and metabolic health. Bridging this gap requires interventions that target these underlying biological hallmarks of aging.

Lifespan Gap

Meaning

The Lifespan Gap, in a clinical and public health context, refers to the quantifiable difference between an individual’s actual chronological age and their predicted maximum lifespan potential, often informed by genetic, lifestyle, and environmental factors. More specifically in longevity science, it is frequently used to highlight the discrepancy between lifespan (the total years lived) and healthspan (the years lived in good health). Addressing this gap is the central goal of preventative medicine and age-management strategies.
