Living Longer, Feeling Worse: Americans Now Spend 14 Years Of Their Lives In Poor Health

The Hidden Cost of Living Longer: A Decade Spent in Poor Health

People around the world are living longer than ever. Thought provokingly, however, a sweeping new global analysis finds those extra years are increasingly spent managing pain, illness, or disability rather than enjoying good health. Worldwide, the average person can now expect roughly 10.7 years of life at less than full health, based on 2023 population data. That figure covers everything from a bad back to a disabling condition. It’s not a sentence to a decade of severe illness, but it does mean a meaningful chunk of the average life gets lived with something wrong.

A major study published in The Lancet Public Health tracked the gap between how long people live and how many years are spent in good health, across 204 countries and territories from 1990 to 2023. Researchers call that difference the ‘morbidity gap,’ and central estimates suggest it widened in 203 of 204 places studied, though uncertainty around individual country numbers was often substantial. In 1990, the average person spent about 8.8 years in poor health. By 2023, that had climbed to 10.7 years, an increase of nearly two years, or about 22%.

Researchers point to a straightforward broad pattern: gains in survival have outpaced gains in healthy years. People are surviving conditions that once would have killed them, and some carry lasting health effects afterward. That’s a reasonable read of the data, though the study itself doesn’t pin the blame on medicine specifically, just on the mismatch between how long people live and how healthy those years turn out to be.

A Pattern That Deepens in Wealthier Countries

Here’s a twist: wealthier nations had the largest gaps between total lifespan and healthy lifespan, not the smallest. In 2023, the highest-income countries averaged a 12.7-year gap. The United States topped the list among individual countries at 14.0 years, meaning Americans spent about 17.8% of their expected lifespan in poor health. That U.S. figure carries real uncertainty, with a 95% range running from 10.8 to 17.5 years. Australia and Canada followed close behind, at 13.9 and 13.7 years.

Nauru, the Solomon Islands, and Laos posted the smallest gaps of any countries studied, but that’s not because those populations age more gracefully. It’s because shorter overall lifespans there leave less time to rack up years of poor health in the first place. Longer life, in other words, tends to come with a bigger absolute morbidity gap simply because there’s more life to fill. The picture gets murkier when looking at the proportion of life spent unhealthy rather than raw years, where the link to national wealth was far less consistent, complicating any simple story that richer automatically means healthier.

What’s Eating Into Healthy Years

So what’s driving the gap? Researchers traced it to a cluster of chronic problems that make life harder without necessarily ending it early. Five categories together accounted for 57.4% of all years lived in poor health globally in 2023. Low back pain and related joint and bone problems topped the list, followed closely by depression and anxiety. Hearing loss, falls, and a grab-bag of other long-term physical conditions rounded out the top five.

None of these make headlines the way heart disease or cancer do, yet they quietly consume an outsized share of people’s wellbeing across adulthood, not just in old age. The gap between healthy years and total years widens steadily through the adult life course rather than piling up only at the very end of life.

Women Carry a Heavier Load

A persistent divide separates men and women. Women live longer almost everywhere, but they also spend more of that life in poor health, a pattern researchers call the ‘gender health paradox.’ In 2023, women faced a gap of 12.1 years, about 15.9% of life expectancy, compared with 9.3 years, or roughly 13%, for men. It held across every region and income level studied, including during the brief disruption of the COVID-19 pandemic, when life expectancy and healthy life expectancy both fell sharply worldwide before trends resumed their prior course.

Risk factors most tied to the widening gap overall also emerged from the study. High blood sugar, high body weight, and childhood or maternal malnutrition ranked among the leading potentially modifiable risks associated with years lived in poor health, alongside tobacco use. In wealthier countries, body weight, blood sugar, and smoking dominated. In lower-income regions, particularly sub-Saharan Africa, child malnutrition and air pollution played larger roles. Because these figures come from statistical modeling rather than direct measurement, researchers reported them as ranges rather than fixed numbers.

Rethinking What ‘Progress’ Means

For decades, global health progress has been measured by one number: how long people live. This study argues that number alone is telling only half the story. A longer life that comes with a decade or more of pain, disability, or chronic illness isn’t the win it looks like on paper, and the fact that nearly every country studied shows the same pattern suggests health systems everywhere have a real gap to close, not just a statistic to celebrate.
