Objectives: To describe Papanicolaou (Pap) test findings and identify prevalence and correlates of dysplastic cervical abnormalities in low-income adolescent females.
Design and setting: This cross-sectional study included a modified random sample of female students ages 16 to 25 years at 54 U.S. Job Corps centers.
Participants: 5,734 female students enrolled in a federal job training program. Admission health records were reviewed and abstracted.
Main outcome measure: Pap test findings using the Bethesda classifications. Pap smear results indicating dysplasia (atypical squamous cells of undetermined significance [ASCUS] with dysplasia) or squamous intraepithelial lesions (low-grade squamous interepithelial lesions [LGSIL] or high-grade squamous intraepithelial lesions [HGSIL]). Participants with less severe findings were compared with those who needed follow-up.
Results: For 71.4% of participants, no abnormalities were found. 15.6% had benign cellular changes, 9.2% had reactive changes, and 9.9% had epithelial cell abnormalities. Of those tested, 5.6% (+/- 0.8%) had dysplastic Pap smear findings, with 0.3% (n = 12) HGSIL. All groups were equally affected, with abnormalities not associated with race/ethnicity, age, geographic region, education level, size of city of residence, or receiving public assistance.
Conclusions: In this population, dysplastic Pap smear results were not uncommon. Findings indicate that Pap screening, alone or in combination with more sensitive tests, can identify cervical abnormalities, including HGSIL, that suggest a need for further evaluation or follow-up.
