Despite medical advances, life expectancy gains are slowing
After nearly doubling over the 20th century, the rate of increase in life expectancy has slowed considerably in the last three decades, according to a new study.
www.sciencedaily.comHere are the latest developments on healthy life expectancy (HALE) from reputable sources:
-
Global outlook: The Global Burden of Disease study projects that global life expectancy will rise by about 4.2–4.9 years by 2050, with increases larger in lower-income regions, but healthy life expectancy gains may lag behind overall life expectancy in many high-income countries. This suggests more years alive but not necessarily in good health, highlighting a growing focus on healthspan alongside lifespan.[2]
-
UK and Europe: Recent UK data show a decline in healthy life expectancy for both men and women, with men around 18 years and women about 22.5 years expected to be spent in poor health for a birth cohort today, underscoring widening health inequality concerns and the need for stronger public health investment. Similar patterns have been reported in Scotland, where HALE has fallen to a ten-year low, reflecting regional disparities in health outcomes.[4][9]
-
Australia and New Zealand: New estimates from the Global Burden of Disease indicate that healthy life expectancy has risen over the past few decades to roughly 70 years in Australia and about 69.4 years in New Zealand, yet improvements in total life expectancy outpace HALE due to persistent risk factors like obesity and cardiovascular disease.[1]
-
Global health perspective: WHO data show that before the COVID-19 pandemic, both life expectancy and HALE were increasing, but the pandemic reversed some of that progress, especially impacting HALE due to delayed management of non-communicable diseases and other health disruptions; ongoing recovery varies by country.[5][7]
-
The broader trend: Several independent analyses published in 2024–2026 emphasize that while life expectancy growth has slowed in many places, the key opportunity lies in slowing aging and extending healthspan through geroscience, risk-factor reduction, and addressing health disparities to ensure more years lived in good health rather than merely longer lives.[3]
Illustrative takeaway:
- If life expectancy rises but HALE stalls or declines in some regions, the proportion of life spent in ill health increases, reinforcing the call for policies that promote preventive care, obesity reduction, blood pressure and cholesterol management, smoking cessation, and access to effective treatments for NCDs.[4][5]
