Cervical pap screening cytological abnormalities among HIV-infected adolescents in the LEGACY cohort.

OBJECTIVES

To determine the prevalence of cervical Pap screening (CPAP-S), identify factors associated with CPAP-S, and explore risk factors for abnormal cervical cytology in female adolescents with perinatally and behaviorally acquired HIV infection.

DESIGN

Cross-sectional.

SETTING

LEGACY is a national observational cohort chart review study of 1478 HIV-infected persons (<age 24 years) managed in 22 HIV specialty clinics in the United States.

PARTICIPANTS

Sexually active females aged 13-24 years in the LEGACY cohort.

MAIN OUTCOME MEASURES: CPAP-S and abnormal cervical cytology.

RESULTS

Of 231 sexually active female LEGACY participants 13-24 years of age 49% had documentation of CPAP-S between 2001 and 2006. Fifty-eight percent of 113 cervical tests were abnormal (2% high-grade). In multivariable analysis, perinatal HIV infection and black race were associated with decreased likelihood of CPAP-S (adjusted prevalence ratio [APR] 0.66, 95% CI 0.45-0.96 and APR 0.74, 95% CI 0.56-0.96, respectively). Presence of any sexually transmitted infection (STI) was independently associated with increased likelihood of CPAP-S (APR 1.56, 95% CI 1.21, 2.02). CD4+ T-lymphocyte count <200 cells/mL and previous STI diagnosis were independently associated with increased likelihood of abnormal cervical cytology (APR 2.19, 95% CI 1.26-3.78 and APR 1.94, 95% CI 1.29-2.92, respectively).

CONCLUSIONS

Among sexually active HIV-infected adolescent females, prevalence of CPAP-S was low and cytology was abnormal in more than half of Pap smears. Perinatally HIV-infected, sexually active females were less likely to undergo CPAP-S than their behaviorally HIV-infected counterparts. Interventions targeted at HIV-infected adolescents and care providers are needed to improve CPAP-S in HIV-infected young women, especially those with perinatally acquired HIV infection.
