A staggering one in eight Americans has been diagnosed with type 2 diabetes,
a new Harris Interactive poll suggests.
And more than one third of those polled have been diagnosed with diabetes or
have a parent, sibling, spouse or child with the condition.
"Type 2 diabetes has become one of the most common and fastest growing
diseases. Fully one in eight adults - approximately 29 million people - now
report that they have been diagnosed with this dangerous condition," said Harris
Poll Chairman Humphrey Taylor.
Added Dr Ronald Tamler, clinical director of the Mount Sinai Diabetes Center
in New York City: "Diabetes is very insidious. You don't know you're in trouble
until the complications hit or until it's so out of control you have
uncontrolled urination and thirst" - two of the common symptoms of diabetes.
Awareness still lacking
While type 2 diabetes is occurring in epic proportions, the new poll also
found that awareness of the disease is still surprisingly low, with only 21% of
those surveyed considering themselves well-versed on the disease. That means the
remaining 79% may not know they're at risk or may already have the disease,
which is known as the "silent" killer.
But people already diagnosed with diabetes tend to be much more aware of the
health risks, with slightly more than two-thirds considering themselves either
"extremely" or "very" knowledgeable about the disease, the poll found.
Still, 35% of respondents with diabetes said their diabetes was only
"somewhat" controlled and 5 percent said it was "not at all" well
"Because diabetes is a chronic condition, the treatment of which is
critically dependent on patient behaviour and self-care, this may be the most
alarming finding," Taylor said.
People understand the risk
On a more encouraging note, many people polled do understand that a number of
factors can contribute to type 2 diabetes, including being overweight (79% of
respondents realise this is a risk factor), diet (74%) and physical inactivity
These numbers were greater among people who had been diagnosed with
Interestingly, 60% of respondents know that genetics can be a component of
type 2 diabetes.
"We have a public perception that type 2 diabetes is entirely a disease of
lifestyle and that is not true," said Dr Robert Ratner, chief scientific and
medical officer of the American Diabetes Association. "There is no question that
lifestyle contributes to it, but the problem is one of biology. Environment
really does play a role but the biology sets them up."
Indeed, certain ethnic groups, including many Native American tribes, bear a
disproportionate diabetes burden, Ratner added.
Most adults, whether they actually have diabetes or not, seem fairly
knowledgeable about the long-term consequences of the disease, which can include
amputation of limbs, blindness, kidney disease and heart disease, the poll
There was an exception. Only 39% of adults overall and 56% of those with type
2 diabetes knew that the disease can cause strokes.
"People need to be aware that this is another disease caused by diabetes that
can be prevented," said Nancy Copperman, director of Public Health Initiatives
at North Shore-LIJ Health System in Great Neck, NY. "The idea of having a stroke
might motivate them to change their lifestyle."
A full and happy life with diabetes
The disease seems to be taking a toll on those polled, with 20% acknowledging
it has been a "significant" burden and 43% saying it has been "somewhat" of a
burden for themselves and their families. The burden comes in the form of
dietary restrictions, medication costs, eye problems, cardiovascular problems
and foot problems.
In addition, 9% of people with type 2 diabetes said the condition has
rendered them unable to work.
Still, with awareness of genetic factors as well as lifestyle contributors,
"you can live a very full and happy life and thrive with diabetes," said Mount
In people with type 2 diabetes, either the body doesn't produce enough of the
hormone insulin or cells can't use the insulin properly. Insulin is necessary
for the body to use glucose - blood sugar - for energy. When glucose builds up
in the blood instead of going into cells, it can lead to diabetes complications,
according to the American Diabetes Association.
The prevalence of type 2 diabetes found in this new poll is higher than that
reported by the US Centers for Disease Control and Prevention, although the CDC
data is more rigorous, Ratner said.
The poll was conducted online within the United States by Harris Interactive,
among 2 090 adults aged 18 and older. The survey was not based on a probability
sample, so no estimate of theoretical sampling error can be calculated.
