A study found a short-term
increase in diabetes risk in people who quit smoking. Another study links each
hour spent sitting and watching TV daily to an increased risk of death.
People who stop smoking often replace cigarettes with food. A new study says
the weight they gain may increase their diabetes risk in the short term.
Type two diabetes is common in people who eat too much and exercise too little
and those with a family history of it. Smoking is another risk factor. But
quitting smoking may carry a temporary risk.
The study found that smokers who quit had a seventy percent increased risk of
developing the disease in the first six years. That was compared to those who
had never smoked.
The risks were highest in the first three years. And the risk returned to
normal after ten years of not smoking.
The researchers say weight gain is probably to blame for the increase. But they
say smokers should stop anyway -- and the real message is not to even start.
Type two diabetes interferes with the body's use of insulin. The substance
produced by the pancreas normally lowers blood sugar during and after eating.
Over time, high blood sugar can lead to blindness, kidney failure, heart
disease and nerve damage.
The study is from the Johns Hopkins University School of Medicine. It appears
in the Annals of Internal Medicine.
Another American study says obesity has become as great a threat to quality of
life as smoking. It compared losses in what are called "quality-adjusted
life years." The study found that losses from obesity are now equal to, if
not greater than, those from smoking.
These days, there are fewer smokers in the country but more people who are
extremely overweight. The findings are based on questions about health-related
quality of life in government telephone surveys.
The study is from Columbia University and the City College of New York. It
appears in the American Journal of Preventive Medicine.
And another study has linked each hour of watching television daily to an
eighteen percent increased risk of death from heart disease. The study of
adults in Australia also found an increased risk of death from others causes.
The findings are published in Circulation: Journal of the American Heart
Lead author David Dunstan at the Baker IDI Heart and Diabetes Institute in Victoria
says the body was designed to move. He says even if people have a healthy body
weight, sitting for long periods of time still has an unhealthy influence on
blood sugar and blood fats.
