Singaporeans are living longer. They are also living sicker.
That is the uncomfortable truth emerging from the world’s most comprehensive study on aging. The island-state now boasts the longest, healthiest lives on Earth. But look closer. The gain isn’t in vitality. It is in time spent managing decline.
A new study published in The Lancet Public Health reveals a stark divergence. While total lifespan has surged, healthy life expectancy is lagging. We are adding years to life, but not necessarily quality to those years.
The Widening Gap Between Living and Health
The research, led by the Institute for Health Metrics and Evolution (IHME) in collaboration with the Yong Loo Lin NUS School of Medicine, analyzed data from 204 countries between 1990 and 2023.
They tracked what experts call the “morbidity gap.” This is simple math: total life expectancy minus healthy life expectancy.
Globally, that gap has widened. On average, people now spend 10.7 years in poor health. That is up from 8.8 years in 1990. It represents a 21.9% increase in the burden of illness.
Singapore’s numbers are more extreme.
The morbidity gap here expanded by approximately 2.35 years. That is a 26.6% jump. The country leads the world in total longevity, yet it also leads in the accumulation of non-fatal health burdens.
“The next frontier for Singapore is not simply to add more years to life… but to reduce the burden of chronic ill-health.” — Assoc Prof Marie Ng, NUS Medicine
This breaks the old assumption known as the “compression of morbidity.” For decades, public health officials believed that medical advances would push illness right up against the moment of death. The idea was simple: stay healthy until the end. Then, die quickly.
The data rejects that. Instead, illness accumulates. It drags on through adulthood. The “bad” years are not compressed. They are expanding.
Who Bears the Burden? The Gender Divide
The crisis hits women harder.
This is the “gender health paradox.” Women live longer, yes. But they live sicker.
In 2023, Singaporean women could expect to live to 87.5. Men? 83.1. But women carry a heavier load. They spend an estimated 12.1 years with health conditions. Men manage 10.4.
Globally, the pattern holds. Women’s morbidity gap is 12.1 years. Men’s is 9.3.
Why does this happen? It is partly biology, partly behavior, and partly healthcare gaps. But the result is consistent. Women outlive men, only to spend more of those extra years in discomfort or disability.
The Silent Killers: Not What You Think
If you want to prevent a stroke or heart attack, you are still right to do so. But the data shows these are not the primary drivers of lost health years.
In Singapore, the top five contributors to the morbidity gap are:
* Musculoskeletal disorders (think low back pain)
* Mental disorders (depression and anxiety)
* Unintentional injuries (falls)
* Diseases of the senses (hearing loss)
* Cardiovascular diseases
Globally, non-fatal conditions account for 57.4% of all morbidity gap years.
Professor Simon Hay, first author of the IHME study, notes that while we have been successful at stopping death, we are failing at preserving function.
“This does not diminish the importance of preventing deaths,” Hay says. “But it highlights that the definition of public health progress should be broadened. We must measure if people are able to live with good health and mobility.”
What Is Causing This? The Risk Factors
The culprits are familiar, yet stubborn.
For Singapore, the leading risks driving these non-fatal illnesses are:
* High fasting plasma glucose (prediabetes and diabetes)
* High body mass index (obesity)
* Occupational risks
* High systolic blood pressure
* Dietary risks
Globally, tobacco use and air pollution still play major roles. But metabolic health is king.
The rise in diabetes and obesity is directly correlated with the rise in the morbidity gap. These conditions do not kill quickly. They erode. They limit movement. They cloud cognition. They keep people out of the workforce long before death.
The New Goal: Healthspan, Not Just Lifespan
Singapore’s public health model has shifted focus. The goal is no longer just to keep people alive. It is to keep them functioning.
Assoc Prof Marie Ng points out that these “non-fatal” conditions have profound effects. They strip away independence. They end careers. They degrade quality of life.
The solution requires a different toolkit.
- Prevention: Tackle obesity and diabetes before they become chronic.
- Early Intervention: Screen for mental health and mobility issues early.
- Rehabilitation: Help people recover function, not just survive episodes.
- Support Systems: Ensure environments (homes, workplaces) accommodate aging bodies.
The metrics are changing. Policymakers are now tracking healthy life expectancy alongside mortality rates. The aim is to turn added years into added good health.
But can it be done?
The gap has widened. The conditions are entrenched in lifestyle and biology. We are watching a generation live longer, but perhaps less well. The technology exists to keep hearts beating. The challenge now is keeping people moving.
That is a harder problem to solve.
