"It appears that at least in terms of survival at older ages with
chronic disease, the medical system in the
United States may be better than the system
in England."
The study expands upon an earlier analysis by Banks and Smith that
found that Americans aged 55 to 64 suffered
from diseases such as diabetes at rates up
to twice those seen among similarly aged
people in England. The trend was observed
across all socioeconomic groups.
Researchers analyzed information from two comparable surveys of
people age 50 and over in the United States
and England -- the Health and Retirement
Survey and the English Longitudinal Survey
of Ageing -- funded by the National
Institute on Aging in the United States.
In the new study, researchers examined the prevalence of illness
among those 55 to 64 and 70 to 80. They also
looked for the first time at the onset of
new illnesses in those age groups in the
United States and England during the years
spanning 2002 to 2006. Finally, researchers
examined trends in death rates in each
country.
The findings showed that both disease prevalence and the onset of
new disease were higher among Americans for
the illnesses studied -- diabetes,
high-blood pressure, heart disease, heart
attack, stroke, chronic lung diseases and
cancer. Researchers found that the higher
prevalence of illness among Americans
compared to the English that they previously
found for those aged 55 to 64 was also
apparent for those in their 70s.
Diabetes rates were almost twice as high in the United States as in
England (17.2 percent versus 10.4 percent)
and cancer prevalence was more than twice as
high in the United States (17.9 percent
compared to 7.8 percent) for people in their
70s.
In spite of both higher prevalence and incidence of disease in
America, death rates among Americans were
about the same in the younger ages in this
period of life and actually lower at older
ages compared to the English.
Researchers say there are two possible explanations why death rates
are higher for English after age 65 as
compared to Americans. One is that the
illnesses studied result in higher mortality
in England than in the United States. The
second is that the English are diagnosed at
a later stage in the disease process than
Americans.
"Both of these explanations imply that there is higher-quality
medical care in the United States than in
England, at least in the sense that these
chronic illnesses are less likely to cause
death among people living in the United
States," Smith said.
"The United States' health problem is not fundamentally a health
care or insurance problem, at least at older
ages," Banks said. "It is a problem of
excess illness and the solution to that
problem may lie outside the health care
delivery system. The solution may be to
alter lifestyles or other behaviors."
The study also investigated the relationship between the financial
resources of individuals in both countries
and how soon they would they would die in
the future.
While poorer people are more likely to die sooner than their more
well-off counterparts, researchers say their
finding supports the view that the primary
pathway between health and wealth is that
poor health leads to a depletion of
household wealth, rather than being poor
causes one's health to decline. Researchers
found that the substantial changes in wealth
that occurred in the years 1992 and 2002 in
the United States through increases in stock
prices and housing prices did not alter the
probability of subsequent death.
