【单选题】MostAdults in U. S. Have Low Risk of HeartDiseaseMore 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 theAmericanCollege ofCardiology. 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 authorDr.Earl S. Ford, from theCenters forDiseaseControl and Prevention inAtlanta, 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 NutritionExamination 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 a high or immediate risk,Dr.Daniel S.Berman, fromCedars-Sinai MedicalCenter in LosAngeles, andDr. NathanD、Wong, from the University ofCalifornia at Irvine, note in a related editorial.
