@entity1 @entity9178 @entity378 @entity272
RATIONALE: The goal for @entity378 ( @entity378 ) elimination in the United States is a @entity378 disease incidence of less than 1 per million U.S. population by 2010, which requires that the @entity9178 ( @entity9178 ) prevalence be less than 1% and decreasing. OBJECTIVES: To estimate the prevalence of @entity9178 in the U.S. population. METHODS AND MEASUREMENTS: Interviews and medical examinations, including @entity272 ( @entity272 ), of 7,386 individuals were conducted in 1999-2000 as part of the National Health and Nutrition Examination Survey (NHANES), a nationally representative sample of the civilian, noninstitutionalized U.S. population. @entity9178 was defined as a @entity272 measurement of >/=10 mm. Associations of age, race/ethnicity, sex, poverty, and birthplace were assessed. Results among the 24- to 74-year-old subgroup were compared with NHANES 1971-1972 data. MEASUREMENTS AND MAIN RESULTS: Estimated @entity9178 prevalence was 4.2%; an estimated 11,213,000 individuals had @entity9178 . Among 25- to 74-year-olds, prevalence decreased from 14.3% in 1971-1972 to 5.7% in 1999-2000. Higher prevalences were seen in the foreign born (18.7%), non-Hispanic blacks/African Americans (7.0%), Mexican Americans (9.4%), and individuals living in poverty (6.1%). A total of 63% of @entity9178 was among the foreign born. Among the U.S. born, after adjusting for confounding factors, @entity9178 was associated with non-Hispanic African-American race/ethnicity, Mexican American ethnicity, and poverty. A total of 25.5% of @entity1 with @entity9178 had been previously diagnosed as having @entity9178 or @entity378 , and only 13.2% had been prescribed treatment. CONCLUSIONS: In addition to basic @entity378 control measures, elimination strategies should include targeted evaluation and treatment of individuals in high-prevalence groups, as well as enhanced support for global @entity378 prevention and control.
