La salud de la mujer / Woman's HealthUna de cada 4 mujeres están infectadas por virus del papiloma
Una de cada 4 mujeres norteamericanas de 14 a 59 está infectada por el virus del papiloma humano (VPH), según una encuesta recintemente publicada. La Dra. Eileen Dunne coordinadora del estudio ha llamado la atención sobre el problema. Muchas de esas mujeres van a desarrollar alteraciones celulares (incluso cáncer de cuello uterino o de vulva) y condilomas genitales. El VPH también produce cáncer de pene y de ano.

¿Cual es la situación en España? No hay datos fidedignos, pero es alarmante por el alto grado de promiscuidad sexual entre la juventud y, sobre todo, por no hacer uso correcto del condón. El tiempo que tarda en aparecer el cáncer es muy variable, llegando a tardar hasta 10 años. En la encuesta norteamericana la mayor tasa de infecciones corresponde a la edad 20-24 años.

Prevalence of HPV infection among females in the United States. Dunne EF, Unger ER, Sternberg M, McQuillan G, Swan DC, Patel SS, Markowitz LE. Centers for Disease Control and Prevention, Atlanta, Ga 30333, USA. dde9@cdc.gov
CONTEXT: Human papillomavirus (HPV) infection is estimated to be the most common sexually transmitted infection. Baseline population prevalence data for HPV infection in the United States before widespread availability of a prophylactic HPV vaccine would be useful. OBJECTIVE: To determine the prevalence of HPV among females in the United States. DESIGN, SETTING, AND PARTICIPANTS: The National Health and Nutrition Examination Survey (NHANES) uses a representative sample of the US noninstitutionalized civilian population. Females aged 14 to 59 years who were interviewed at home for NHANES 2003-2004 were examined in a mobile examination center and provided a self-collected vaginal swab specimen. Swabs were analyzed for HPV DNA by L1 consensus polymerase chain reaction followed by type-specific hybridization. Demographic and sexual behavior information was obtained from all participants. MAIN OUTCOME MEASURES: HPV prevalence by polymerase chain reaction. RESULTS: The overall HPV prevalence was 26.8% (95% confidence interval [CI], 23.3%-30.9%) among US females aged 14 to 59 years (n = 1921). HPV prevalence was 24.5% (95% CI, 19.6%-30.5%) among females aged 14 to 19 years, 44.8% (95% CI, 36.3%-55.3%) among women aged 20 to 24 years, 27.4% (95% CI, 21.9%-34.2%) among women aged 25 to 29 years, 27.5% (95% CI, 20.8%-36.4%) among women aged 30 to 39 years, 25.2% (95% CI, 19.7%-32.2%) among women aged 40 to 49 years, and 19.6% (95% CI, 14.3%-26.8%) among women aged 50 to 59 years. There was a statistically significant trend for increasing HPV prevalence with each year of age from 14 to 24 years (P<.001), followed by a gradual decline in prevalence through 59 years (P = .06). HPV vaccine types 6 and 11 (low-risk types) and 16 and 18 (high-risk types) were detected in 3.4% of female participants; HPV-6 was detected in 1.3% (95% CI, 0.8%-2.3%), HPV-11 in 0.1% (95% CI, 0.03%-0.3%), HPV-16 in 1.5% (95% CI, 0.9%-2.6%), and HPV-18 in 0.8% (95% CI, 0.4%-1.5%) of female participants. Independent risk factors for HPV detection were age, marital status, and increasing numbers of lifetime and recent sex partners. CONCLUSIONS: HPV is common among females in the United States. Our data indicate that the burden of prevalent HPV infection among females was greater than previous estimates and was highest among those aged 20 to 24 years. However, the prevalence of HPV vaccine types was relatively low.
