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 Prevention1 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 participated 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.2 By contrast3, 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 a high or immediate risk4, 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.

答案與題解：

1.A文章第一段提到,美國(guó)80%以上的成年人未來(lái)十年內(nèi)患心臟病的風(fēng)險(xiǎn)低于10%，而文章第六段進(jìn)而表明該數(shù)字是低的。

2.B文章第四段提到,未來(lái)十年內(nèi),美國(guó)成年人患心臟病的風(fēng)險(xiǎn)高于10%的可分為兩類,一類是10%至20%之間的占15%，另一類是20%以上的占3%。

3.B文章第三段提到,有13,769人參加了此次調(diào)查,即有一萬(wàn)多人參加了此次調(diào)查,而“more than 100 thousand people”表示的是“十萬(wàn)多人”。

4.C文章第五段提到,男人進(jìn)入最高風(fēng)險(xiǎn)組的概率大于女人,但并沒(méi)有表明參加此次調(diào)查的男性多于女性。

5.B文章第五段提到,種族對(duì)患病風(fēng)險(xiǎn)的分布影響很小。

6.A文章第五段提到,年齡越大,進(jìn)入最高風(fēng)險(xiǎn)組的比例也就越大。

7.C文章第七段提到,研究人員說(shuō),只有采取積極的治療措施和公共衛(wèi)生政策才能降低所有人群患病的風(fēng)險(xiǎn)概率,但并沒(méi)有提及美國(guó)政府是否會(huì)這樣做。
