New U.S. Plan for Disease Prevention
Urging Americans to take responsibility for their health, Health and Human Services Secretary Tommy Thompson on Tuesday launched a $15 million program to try to encourage communities to do more to prevent chronic diseases like heart disease, cancer and diabetes (糖尿病).
The initiative highlights the costs of chronic diseases—the leading causes of death in the United States—and outlines ways that people can prevent them, including better diet and increased exercise.
"In the United States today, 7 of 10 deaths and the vast majority of serious illness, disability and health care costs are caused by chronic diseases," the Health and Human Services department said in a statement.
The causes are often behavioral--smoking, poor eating habits and a lack of exercise.
"1 am convinced that preventing disease by promoting better health is a smart policy choice for our future," Thompson told a conference held to launch the initiative.
"Our current health care system is not structured to deal with the rising costs of treating diseases that are largely preventable through changes in our lifestyle. choices."
Thompson said heart disease and strokes will cost the country more than $351 billion in 2003.
"These leading causes of death for men and women are largely preventable, yet we as a nation are not taking the steps necessary for us to lead healthier, longer lives," he said.
The $15 million is designed to go to communities to promote prevention, pushing for changes as simple as building sidewalks to encourage people to walk more.
Daily exercise such as walking can prevent and even reverse heart disease and diabetes, and prevent cancer and strokes.
The money will also go to community organizations, clinics and nutritionists who are being encouraged to work together to educate people at risk of diabetes about what they can do to prevent it and encourage more cancer screening.
The American Cancer Society estimates that half of all cancers can be caught by screening, including Pap tests (巴氏试验) for cervical (子宫颈) cancer, mammograms (乳房×线照片) for breast cancer, colonoscopies (结肠镜检查), and prostate (前列腺的) checks.
If such cancers were all caught by early screening, the group estimates that the survival rate for cancer would rise to 95 percent.
Which of the following is NOT true of chronic diseases in the US？

Crystal Ear
One day a friend asked my wife Jill if I wanted a hearing aid. "He certainly does," replied Jill. After hearing about a remarkable new product, Jill finally got up the nerve to ask me if I'd ever thought about getting a hearing aid. "No way," I said. "It would make me look 20 years older. .... No, no," she replied. "This is entirely different. It's Crystal Ear!"
Jill was right. Crystal Ear is different--not the old-styled body worn or over-the-ear aid, but an advanced personal sound system so small that it's like contacts (隐形眼镜) for your ears. And Crystal Ear is super-sensitive and powerful, too. You will hear sounds your ears have been missing for years. Crystal Ear will make speech louder, and the sound is pure and natural.
I couldn't believe how tiny it is. It 'is smaller than the tip of my little finger and it's almost invisible when worn. There are no wires, no behind-the-ear device. Put it in your ear and its ready-to-wear mold (形状) fits comfortably. Since it's not too loud or too tight, you may even forget that you're wearing it？ Use it at work or at play. And if your hearing problem is worse in certain situations, use Crystal Ear only when you need it.
Hearing loss, which occurs typically prior to teenage years, progresses throughout one's lifetime. Although hearing loss is now the world's number one health problem, nearly 90 percent of people suffering hearing loss choose to leave the problem untreated. For many millions, treating hearing loss in a conventional way can involve numerous office visits, expensive testing and adjustments to fit your ear. Thanks to Crystal Ear, the "sound solution" is now convenient. Almost 90 percent of people with mild hearing loss, and millions more with just a little hearing drop-off (下降), can be dramatically helped with Crystal Ear. Moreover, its superior design is energy-efficient, so batteries can last months. Crystal Ear is now available to help these people treat their hearing loss with a small hearing amplifier (放大器).
