When one person gains weight, close friends often gain weight, too. The study was published last month in the New England Journal of Medicine. The study sh

16、owed that when a person becomes severely overweight, there is a 57% increased chance that one of their friends will be, too. A sister or brother of the overweight person has a 40% increased chance of becoming fat. The increased risk for a wife or husband is a little less than that.2. in the United S

17、tates, experts estimate that up to 4% of adults and up to 8% of young children have food allergies. Every year these allergies cause about 30，000 cases of anaphylaxis, a sever reaction that requires immediate treatment. It can result in trouble breathing and in some cases death. The National Institu

18、te of Allergy and Infectious Diseases say 100 to 200 people die.

24、ple. However experts say a lot of people do not follow it. A recent study found that many Americans fail to wash their hands after using public toilets. More than 95% of Americans questioned said they always wash their hands after using public restrooms. However, the study found that only 67% of the

25、m actually do so. The study also found that American men are less likely than women to wash their hands after suing a public restroom. The American Society for Microbiology announced the findings. Judy Daly works for the group. She admits that hand washing may seem an unusual subject to study. But s

26、he says hand washing is a very serious issue. Experts say hand washing is the simplest and most effective way to reduce the spread of infectious diseases. Infections can spread by touching surfaces that have harmful organisms on them. Shaking hands with another person also can spread infection. Harm

27、ful bacteria may enter your body if you touch your mouth, nose or eyes. Among the most common infections spread by hand are colds, influenza, and throat and ear infections.

28、 serious diseases like cholera and hepatitis are spread this way, too. Many patients in hospitals also get infections. Some die from them.

31、ientists report in the journal Lancet that nine factors that people and societies can control cause nearly 2.5 million cancer cases each year. That is about 1/3 of the seven million annual global total. These include caners of the lung, breast, bladder, cervix, liver, pancreas, mouth and digestive t

32、ract. Leading the list of causes is smoking, which the researchers say is responsible for 20% of preventable cancers. Alcohols use and low consumption of fruits and vegetable cause another 5% each. Also significant are overweight and obesity, physical inactivity, urban air pollution, indoor smoke fr

33、om household cooking, contaminated injections in health clinics, and unsafe sex. One of the studys co-authors, Harvard University public health researcher Majid Ezzati, says the statistics reflect data on cancer deaths in 2001. He expects an increase in the proportion of death from these risk factor

34、s. “The estimates that we have are looking at what happens today as a result of past exposure. So one-third of cancer deaths today would have been avoided had these lifestyle and environmental exposures not been present. If we were to speculate about the future, we could actually say more than one i

35、n every three cancer deaths could be avoided because things such as smoking actually have been going up in many countries in the world, so we actually havent seen the full effects of it yet. ” The new study finds that developing countries had more than twice as many preventable cancer deaths as rich

36、 nations. Among the developing regions, Eastern Europe and Central Asia had the highest proportion of cancer deaths attributable to the nine risk factors - 39 percent compared to the global average of 35 percent. Furthermore, Mr. Ezzati says twice as many men as women died from such cancers. Mr. Ezz

37、ati and his colleagues say that the best option for reducing the increasing global burden of cancer is through lifestyle and environmental modifications because medical science is not close to controlling it. Despite the drive to seek cancer cures, they point out that advances in treatment have not

38、been as effective as for other chronic diseases, and effective screening methods are available for only a few cancers. “There is a huge amount of resources going in to the war on cancer and to biomedical technologies. It is certainly not matched by equivalent research and application of risk factor

39、reduction. So I think should be a reminder of how large the role of prevention can be for reducing cancer deaths.”Part D 1 42 doctors, dieticians, pharmacists2 24 hours a day, seven days a week3 Clearing house4 Free1. board-certified doctors2. 24 hours a day, seven days a week3. practice medicine 4.
