Prevalence of circumcision in men in the United States: data from the National Health and Nutrition Examination Survey (NHANES), 1999-2002
Background: Male circumcision has been shown to reduce the risk for HIV infection. The objective of this study is to describe the prevalence and trends of circumcision in the United States.
Methods: Information about circumcision status and sexual behaviors was collected as part of National Health and Nutrition Examination Surveys during 1999-2002. The questionnaire concerning circumcision status and sexual behaviors was administered using audio computer assisted self-interview. Medical artwork was used to aid the reporting of circumcision status.
Results: Data on circumcision status were available for 4,139 men/boys born between 1940 to 1988. The overall prevalence of circumcision was 79% (95% confidence interval (CI) 77-81). Circumcision prevalence varied by race-ethnicity: 89% in non-Hispanic whites, 78% in non-Hispanic blacks, and 41% in Mexican Americans. Among men born from 1940 to 1979 in the United States, temporal trends in circumcision prevalence differed by race-ethnicity: circumcision prevalence increased in Non-Hispanic blacks and Mexican Americans but was relatively unchanged in non-Hispanic whites. Overall, among men born in the 1980s in the United States, the prevalence of circumcision (83%) significantly decreased from its peak (91%) in the 1970s (p<0.001). Circumcision prevalence was higher in men with more education (85% in men > high school compared to 73% in men < high school, p<0.001). In multivariate analyses, circumcision status was not associated with age at first sex, number of lifetime sexual partners, or the likelihood of having ever had a male partner. Among the 21 HIV-infected men identified in the survey, 7 were uncircumcised and 14 were circumcised (prevalence ratio =1.9, 95% CI 0.5-6.7).
Conclusions: In the United States the prevalence of circumcision is high, but differs by race-ethnicity. The prevalence of circumcision decreased in those born in the 1980s compared to those born in the 1970s. Sexual behaviors did not differ by circumcision status.
