Mapping drivers of life expectancy change in Asia from 1990 to 2023

Abstract

Life expectancy is a key indicator of population health and an important guide for health policy. Although Asia represents approximately 60% of the global population, studies of longitudinal trends in life expectancy and their underlying drivers across Asian countries remain limited, with most previous research focused on western or high-income settings. Here we provide a comprehensive analysis of life expectancy, cause-specific mortality and risk factors in 1990–2023 across 34 Asian countries and territories, utilizing data from the Global Burden of Disease Study 2023. Life expectancy increased in all countries and territories between 1990 and 2023, with the largest annual gains observed in South Asia and the smallest annual gains in high-income Asia Pacific countries and territories. Reductions in cardiovascular disease mortality were the primary contributors to life expectancy gains in Central Asia, East Asia and high-income Asia Pacific, whereas declines in diarrhoeal diseases and tuberculosis contributed most in South and Southeast Asia. In 2019–2023, life expectancy declined in several Asian regions, largely driven by the COVID-19 pandemic, with a nearly two-year loss in the first year of the pandemic. The causes of changes in life expectancy and the contributing risk factors varied across regions and countries/territories. Therefore, under the principles of proportional universalism, proactive and effective policies at both regional and national levels are essential to reduce premature mortality and reduce life expectancy inequalities across Asia.
