Among high-income countries, US shows slowest progress in reducing risk | |
of chronic disease deaths, new study finds | |

Among all high-income Western countries, the United States has shown | |
the worst performance in reducing the probability of dying from chronic | |
diseases, a new study finds. | |
From 2010 to 2019, deaths due to chronic diseases declined in most age | |
groups in the US but increased among adults 20 to 45, “a rare | |
phenomenon in high-income western countries,” according to the study, | |
published Wednesday in the journal . | |
The study, led by researchers at Imperial College London, analyzed data | |
on 185 countries and territories and found that, from 2010 to 2019, the | |
probability of dying by age 80 from a noncommunicable disease — such | |
as cancer, heart disease and stroke — declined in most of those | |
countries, but the decline had slowed compared with the previous | |
decade. | |
“The risk of dying – or what we call probability in the paper – | |
from chronic diseases in most countries in the world is coming down,” | |
said Majid Ezzati, the study’s senior author and a professor in the | |
School of Public Health at Imperial College London and Imperial Global | |
Ghana. | |
“But we were doing better before,” he said. | |
Among the 25 high-income Western countries in the study, Denmark had | |
the largest decline in chronic disease deaths, while the United States | |
had the smallest, and Germany did only slightly better than the United | |
States. | |
“The US is the slowest, but it’s by no means the exception,” | |
Ezzati said. “Germany is doing nearly as badly.” | |
Among the high-income Western countries, there were small to moderate | |
declines in the probability of dying from a chronic disease by age 80 | |
from 2010 to 2019 overall. But the researchers noted that a possible | |
reason why the declines were not larger as a group is that in many | |
countries, neuropsychiatric conditions such as dementia increased and | |
contributed unfavorably to the trends. | |
The new study included data from the World Health Organization’s , | |
and the team of researchers analyzed deaths between time periods, | |
countries and by age groups: young adults 20 to 45, working-age adults | |
45 to 65, and older adults 65 to 80. | |
The data showed that from 2010 to 2019, chronic disease deaths declined | |
in about 80% of the world’s countries, home to more than 70% of the | |
global population. | |
The reasons for widespread decline in chronic disease mortality could | |
be tied to improvements in diagnosing and treating chronic diseases, | |
according to the study. For instance, there have been changes in | |
clinical guidelines as well as increases in the use of certain | |
medications and the early detection of certain cancers. | |
But in about 60% of countries, either the decline in chronic disease | |
deaths from 2010 to 2019 was smaller than it had been in the preceding | |
decade or there was a reversal of an earlier decline, the data showed. | |
“The countries that did really well did well both in older and | |
working ages. Countries that did really badly did badly in both older | |
and working ages,” Ezzati said. “And then there was some tradeoff | |
between these. Some places never slowed down in older ages, but they | |
have in working ages, and vice versa.” | |
From 2010 to 2019, Finland, Norway and Denmark all had a slower decline | |
in chronic disease deaths among older ages than they had in the | |
previous decade. But they still maintained significant progress in | |
reducing the risk of chronic disease deaths overall because that slower | |
decline among older adults was countered by faster declines among | |
working-age adults. | |
In the United States, small reductions in mortality among older adults | |
were combined with a stagnation among working-age adults and increases | |
in mortality among young adults, leading to the nation’s poor | |
performance compared with other high-income Western countries. | |
The study did not analyze why some countries had greater improvements | |
than others in reducing the probability of chronic disease deaths, but | |
Ezzati had some ideas. | |
In both high-income Western countries that performed poorly compared | |
with their peers – the United States and Germany – there are | |
segments of the population in which there has been less investment in | |
public health, he noted, and these disparities in investment can lead | |
to broad barriers to accessing care. | |
For instance, a barrier can be not having a primary care physician in | |
your local area, which can lead to the delayed screening for and | |
diagnosis of chronic conditions, Ezzati said. | |
Many Americans live in areas where critical-care services are lacking. | |
It’s estimated that . And a CNN analysis has found that people living | |
in 16% of the mainland United States are 30 miles or more from the | |
nearest hospital. | |
The United States also has had a rise in the probability of dying from | |
neuropsychiatric conditions, such as dementia and alcohol use | |
disorders, which did not appear to offset continued declines in deaths | |
from cancers and cardiovascular diseases – and these trends could | |
have contributed to the nation’s poor performance in reducing chronic | |
disease mortality, according to the researchers. | |
The new study was published a day after the Trump administration | |
released the ’s action plan on reducing in the United States. | |
US Health and Human Services Secretary Robert F. Kennedy Jr. has made | |
tackling chronic diseases a primary focus. In an , Kennedy noted that | |
the share of , according to data from the US Centers for Disease | |
Control and Prevention. | |
Elena Ladas, a professor of global integrative medicine at Columbia | |
University and an expert on noncommunicable diseases in young people, | |
said she is optimistic the United States is heading toward embracing | |
wellness as a prevention tool to reduce chronic disease deaths, but she | |
wants to see a clear implementation plan. | |
“They’re talking about the right things: Ultraprocessed foods need | |
to really be minimized, and exposures to pesticides and environmental | |
contaminants,” Ladas said of the MAHA report. “They’re talking | |
about what I think a lot of epidemiologists and clinicians have been | |
saying for a very long time. But how they’re going to implement that | |
remains to be seen.” | |
Ladas, who was not involved in the new study but has done public health | |
work in nearly two dozen countries, said the United States should | |
“think about wellness comprehensively” to reduce the burden of | |
chronic disease. | |
“Wellness approaches include good nutrition. We need to make healthy | |
food reasonably priced. A lot of times, farmer’s markets are more | |
expensive than the grocery store. You don’t see that in Europe. In | |
Europe, farmer’s markets are far less expensive than grocery | |
stores,” Ladas said. | |
“And mental health can include meditation and deep-breathing,” she | |
added. “There are more holistic wellness approaches to include for a | |
lot of these chronic conditions versus being only medication-based | |
resolutions. You need both.” | |
