Cervical cancer can be diagnosed early by cancer screening programs. The aim of this study was to evaluate the cervical smear test results of healthy women. We enrolled 94,848 healthy women from 30-65 years of age in whom both HPV typing and a cervical smear test was performed between 2014 and 2017. HPV was detected in 3001 women (3.16%). The mean age was 42 ± 8.94 years old. Positive HPV types were HPV16; HPV16 and multiple infection; HPV31; HPV51; HPV39; HPV52; HPV56; HPV18; HPV68; HPV35; HPV18 and multiple infection; HPV58; HPV45; HPV59; HPV16, HPV18 and multiple infection; HPV16 and 18; and HPV33, in descending order. Cytology results were normal in 63.61%. We also identified atypical squamous cells of undetermined significance in 6.60%, atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion in 0.73%, low-grade squamous intraepithelial lesion in 10%, high-grade squamous intraepithelial lesion and atypical glandular cells in 0.53%, and adenocarcinoma in situ in 0.03%. In terms of HPV subtypes, abnormal smear results were divided into an HPV16, HPV18, and multiple infection group (25%), an HPV35 group (23.61%), an HPV 16 and multiple infection group (22%), and an HPV16-only group (21.85%). Most cases of HPV (39.02%) and abnormal cytology (43.04%) were detected between the ages of 30 and 40. This study is remarkable because it is a community-based study and includes a large population of healthy women to detect HPV prevalence, its subtype, and abnormal smear results.
