Most Adults in US Have Low Risk of Heart Disease
More than 80 percent of US adults have a less than 10-percent risk of developing heart disease in the next 10 years,according to a report in the Journal of the American College of Cardiology.Just 3 percent have a risk that exceeds 20 percent.
"I hope that these numbers will give physicians,researchers,health policy analysts,and others a better idea of how coronary heart disease is distributed in the US population,"lead author Dr.Earl S.Ford,from the Centers for Disease Control and Prevention in Atlanta,said in a statement.
The findings are based on analysis of data from 13,769 subjects,between 20 and 79 years of age,who narticipated in the Third National Health and Nutrition Examination Survey from 1988 to 1994.
Overall,82 percent of adults had a risk of less than 10 percent,15 percent had a risk that fell between 10 to 20 percent,and 3 percent had a risk above 20 percent.
The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group.By contrast,race or ethnicity had little effect on risk distributions.
Although the report suggests that most adults have a low 10-year risk of heart disease,a large proportion have ahigh or immediate risk,Dr.Daniel S.Berman,from Cedars-Sinai Medical Center in Los Angeles,and Dr.Nathan D.Wong,from the University of California at Irvine,note in a related editorial.
Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward,they add.

13 Million Americans Suffer from Social Anxiety Disorder
Social anxiety disorder prevents some 15 million Americans from leading normal social and romantic lives,a new survey finds.
The disorder leaves many isolated,ashamed and often misdiagnosed. Thirty-six percent of those with social anxiety disorder have symptoms for 10 years or more before seeking help,the Anxiety Disorders Association of America reports.
“Social anxiety disorder is when somebody has an intense,persistent and irrational fear of social or performance situations,”Jerilyn Ross,the association's president and CEO,said during a teleconference Wednesday.
“The condition causes people to avoid common,everyday situations and even other people for fear of being judged or criticized or humiliated or embarrassing themselves,”Ross said.
Social anxiety disorder can interfere with daily routines and job performance,Ross noted.“It also makes it very difficult for people to develop friends and romantic partnerships,” she said.
People with this disorder recognize their fear is excessive and irrational,Ross noted. “But they feel powerless to do anything about it,”she said.
Social anxiety disorder can start in the early teens,Dr. Mark H.Pollack,director of the Center for Anxiety and Traumatic Stress Disorders and a professor of psychiatry at Harvard Medical School,said during the teleconference.
“This is a disorder that starts affecting people early on,”Pollack said.“The typical age of onset is early adolescence,age 12 or 13,and many individuals report a history of anxiety dating back to earlier childhood.”
The disorder also has physical symptoms,including heart palpitations,feelings that their throat will close up,sweating,blushing,faintness,trembling and stammering,Ross said.
Among people with the disorder,75 percent said the condition affected their ability to do normal activities. In addition,69 percent said they didn't want people to think they were crazy,and 58 percent said they were embarrassed by their condition,Ross said.
However,when the condition is diagnosed and treated,many reported improvement in their lives.In fact,59 percent who were receiving treatment said treatment had a positive effect on their ability to have a romantic relationship.In addition,39 percent who had received treatment said knowing that treatment can be successful aided their decision to get help,Ross noted.

The symptoms of social anxiety disorder include all the following EXCEPT______.
A: heart palpitations
B: sore throat
C: sweating
D: blushing

Baseline Exam Is Key to Eye Health
Even people with no signs or risk factors for eye disease can suffer vision loss and need to get baseline（基线）eye exams at age 40,says the American Academy of Ophthalmology(AAO)（美国眼科学会）.
The reminder（提示）is part of the AAO's EyeSmart campaign to mark Save Your Vision Month in February.
“Many eye diseases progress without any warning signs,”Dr. Stephanie Marioneaux,a clin-ical correspondent for the AAO,said in a prepared statement.“Gradual changes in vision can af-fect your ability to function independently and have confidence in your abilities.”
Based on the findings from the initial screening,an eye doctor will create a schedule for follow-up eye exams.
People of any age who have symptoms of eye disease or are at high risk due to family history, diabetes（糖尿病）or high blood pressure should consult with their eye doctor to determine how often they should have their eyes checked,the AAO recommends .By 2020,43 million Americans will be at significant risk for vision loss or blindness due to age-related eye diseases such as cata-racts（白内障）and glaucoma（青光眼）. That's a more than 50 percent increase over the current number of Americans with such vision-threatening diseases.
But many Americans are unconcerned about the risk of vision loss.Only 23 percent of Amer- icans are very concerned about losing their vision,while most feel weight gain or joint or back pain are greater worries than vision loss,according to an AAO survey conducted for its EyeSmart campaign.

Everyone need to get baseline eye exams at age 40,according to the American Academy of Ophthalmology.

Obesity:the Scourge of the Western World
Obesity is rapidly becoming a new scourge of the western world,delegates agreed at the 11th European Conference on the issue in Vienna Wednesday to Saturday. According to state-ments before the opening of the conference一of 2,000 specialists from more than 50 countries一1.2 billion people worldwide are overweight,and 250 million are obese.
Professor Bernhard Ludvik of Vienna General Hospital said:“Obesity is a chronic ill-ness.In Germany,20 percent of the people are already affected,but in Japan only one per-cent.”But he said that there was hope for sufferers thanks to the new scientific discoveries and medication.
Professor Friedrich Hopichler of Salzberg said:“We are living in the new age(but)with the metabolism of a stone-age man.”“I have just been to the United States.It is really terni-ble.A pizza shop is springing up on every corner. We have been overrun by fast food and Co-ca-Cola-ization.”
Many of the experts stressed that obesity was a potential killer. Hopichler said:“Eighty percent of all diabetics are obese,also fifty percent of all patients with high blood pressure and fifty percent with adipose tissue complaints.”“Ten percent more weight means thirteen percent more risk of heart disease.Reducing one's weight by ten percent leads to thirteen percent lower blood pressure.”
Another expert Hermann Toplak said that the state health services should improve their financing of preventive programs.“Though the health insurance pays for surgery( such as re-ducing the size of the stomach)when the body-mass index is more than 40.That is equivalent to a weight of 116 kilograms for a height of 1.70 meters.One should start earlier.”
Ludvik said that prevention should begin in school.“Child obesity(fat deposits)correlates with the time which children spend in front of TV sets.”The consequences were only apparent later on. No more than fifteen percent of obese people lived to the average life ex-pectancy for their population group.

It seems that the______people are least affected by obesity among the developed countries and areas mentioned in the passage.

Exercise Can Replace Insulin for Elderly Diabetics
Most old people with so-called type Ⅱ diabetes could stop taking insulin if they would do brisk exercise for 30 minutes just three times a week,according to new medical research results reported in the Copenhagen newspaper Berlingske Tidende on Monday.
Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet's Center
for Muscle Research showed that physical exercise can boost the body's ability to utilise insulin by 30 percent,the newspaper reported.
This is equal to the effect most elderly diabetics get from their insulin medication today,it said.
Researchers had a group of non-diabetic men and a group of men with type II,all more than 60 years of age,exercise on bicycles six times a week for three months.After the three months the doctors measured how much sugar the test subjects'muscles could utilise as a measure for how well their insulin worked.
Associate Professor Dr.Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non-exercising persons.
"This means that the insulin works just as well for both groups.Physical exercise cannot cure people of diabetes,but it can eliminate almost all their symptoms.At the same time it can put off the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment,"Dela was quoted as saying.
Insulin is a hormone produced by the pancreas,controlling sugar in the body and used against diabetes.
Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to work up a sweat,but that the activity has to be maintained since it wears off after five days without sufficient exercise。
Most diabetics realise that they have to watch their diet while remaining unaware of the importance of exercise,Dela added.

Physical exercise may increase the body ability to utilise insulin by______.
A:70 percent
B:30 percent
C:60 percent
D:only a few percent
