N2 - Cervical cancer is the leading malignant neoplasm in women in Taiwan. In order to compare the validity of various cervical neoplasia screening methods, estimate the prevalence of low- and high-grade squamous intraepithelial lesions (LSIL and HSIL), and identify risk factors for LSIL and HSIL, a community-based cervical neoplasia screening program was implemented in Sanchi, Chutung, Potzu, Kaohsu, Makung, Huhsi, and Paihsa townships, Taiwan. Both cervical smears and cervicograms were used for the screening of cervical neoplasia. Subjects who had positive cervical smears, cervicogram, or both, were further confirmed by colposcopy-guided biopsy. A total of 10,628 married women aged 30 to 64 years were recruited from seven study townships which gave a response rate of 25.2%. Among 667 subjects who screened positive, 555 (82%) underwent colposcopy-guided biopsy. The age-adjusted prevalence was 3.4% for LSIL and 1.7% for HSIL. The biopsy-confirmed rates for cervical smear-detected LSIL and HSIL were 62.8% and 80.6%, respectively; while 56.6% of minor lesions and 22.2% of major lesions identified by cervicogram were biopsy-confirmed as LSIL and HSIL, respectively. The sensitivity of detecting LSIL was higher for cervicograms (79.3%) than for cervical smears (16.7%), and cervicograms had a lower sensitivity in detecting HSIL (48.4%) than cervical smears (90.0%). Multiple logistic regression analysis showed a striking geographical variation in prevalence of LSIL and HSIL. The prevalence of LSIL decreased with the increase in age, and increased with the duration of taking oral contraceptives. The prevalence of HSIL increased with the parity and the duration of taking oral contraceptives and was also significantly associated with the history of cervical cancer among mother and sisters. It is suggested that improvements in the participation rate of cervical neoplasia screening would promote women's health in Taiwan.
