Risk of death is 3.5 t0 5 times greater for obese smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 t0 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 t0 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.

In many societies, there is often greater acceptance of light skin than dark skin.Light skin may be seen as a mark of beauty, intelligence and success.These beliefs can lead to social pressure even within the same racial or ethnic group, if some members are darker skinned than others.
The result is that skin lightening has become a common activity across Africa, Asia and other areas of the world.More and more people with dark skin are using skin-lightening products, even if they may face health risks.
They believe that having whiter skin will improve their lives.Many people think they will have a better chance of getting a job or marrying into a better family.Or they want to look like what their society generally considers beautiful.
Some beauty care products and soaps contain chemicals that make skin lighter.This process is also called bleaching.But some of the chemicals are extremely dangerous.One of the chemicals has been linked to kidney (肾) damage and some kinds of cancer.It also causes low birth weight in babies when mothers use it during pregnancy.
At first, bleaching products make the skin color lighter.But after long-term use they can cause problems.They can even make some skin darker.The chemicals in the products block and break down the natural process that gives color to skin.The skin loses its natural barrier to protect against sunlight.Then the skin can become thick and discolored.Usually the person will use more of the product in an effort to correct the problem, but this only makes it worse.
Fatimata Ly treats skin conditions in the Senegalese capital,Dakar.Doctor Ly says skin bleaching has become a problem throughout Senegal.She says the chemicals are now more dangerous because they are stronger.Some cases have resulted in blackened fingernails, infections and permanent skin damage.
And these are not the only risks.Experts say some people who change their skin color suffer emotional damage.They feel regret and sadness.They feel that instead of risking their health, they should have learned to love and accept their skin color as it was.
1.Which of the following words can replace the underlined word “bleaching”?
