Background: Many strategies are required for cervical cancer reduction eg provision of education cautious sexual behavior, HPV vaccination, and early detection of preinvasive cervical lesions and invasive cancer Basic health data for cervical cytology/ HPV DNA and associated factors are important to make an appropriate policy to fight against cervical cancer Aims: To assess the prevalence of abnormal cervical cytology and/or HPV DNA and associated factors, including sexual behavior, among Bangkok Metropolitan women Materials and Methods: Thai women, aged 25to65 years old, had lived in Bangkok for 5 years were invited into the study Liquidbased cervical cytology and HPV DNA tests were performed Personal data were collected Main Outcomes Measures: Rates of abnormal cytology and/ or highrisk HPV (HRHPV) and factors associated with abnormal test(s) were studied Results: Abnormal cytology and positive HRHPV were found in 63% (279/4442 women) and 67% (295/4428), respectively The most common abnormal cytology was ASCUS (35%) while the most common HRHPV genotype was HPV 16 (14%) followed by HPV 52 (10%), HPV 58 (09%), and HPV 18 and HPV 51 at equal frequency (07%) Both tests were abnormal in 16% (71/4428 women) Rates of HRHPV detection were directly associated with severity of abnormal cytology: 54% among normal cytology and 130%, 308%, 400%, 395%, 563% and 1000% among ASCUS, ASCH, AGCNOS, LSIL, HSIL, and SCC, respectively Some 5% of women who had no HRHPV had abnormal cytology, in which 03% had HSIL Factors associated with abnormal cytology or HRHPV were: age 40 years, education lower than (for cytology) or higher than bachelor for HRHPV), history of sexual intercourse, and sexual partners 2 Conclusions: Rates for abnormal cytology and HRHPV detection were 63% and 67% HRHPV detection was directly associated with severity of abnormal cytology Significant associated factors were age 40 years, lower education, history of sexual intercourse, and sexual partners 2
