第一篇 Most UK Adults Have Low Risk of Heart Disease
More than 80 percent of UK adults have a less than 10-percent risk of developing heart disease in the next 10 years, according to a report from WHO.
"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 UK population，" lead author Dr. Earl Ford, from the Centers for Disease Control and Prevention in London, said in a statement.
The findings are based on analysis of data from 13,769 subjects，between 22 to 70years of age, who participated in the Third National Health and Nutrition Examination Survey from 1990 to 1995.
Overall, 82 percent of adults have a risk of less than 10 percent, 15 percent had a risk that fell from 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 in risk distributions.
Although the report suggests that most adults have a low 10-year risk of heart disease, a large proportion of them have a high immediate risk, Dr. Daniel Burman，from the Medical Center in Liverpool, noted in a related journal.
Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward, he said.
The percentage of most UK adults likely to develop heart disease in the next 10 years is A．above 3%.
B．below 10%.
C．above 20%.
D．0% to 20%.
