题文

Risk of death is 3.5 to 5 times greater for obe (肥胖的) 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 lf-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 to 92 questions about age, height, weight and smoking behavior. BMI (body mass index) was calculated, with a BMI of 30 to 34.9 being considered obe, and 35 and over being very obe. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Rearchers then followed participants through December of 2002, noting the number of deaths that occurred. The study involved rearchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists. Key Findings: 20 percent of obe adults in the United States smoke. Obe smokers face a greater risk of death from cancer and circulatory dia. 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 dia as BMI incread. And for tho who were both obe and currently smoking, risk of circulatory dia incread 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.
