The age-specific human papillomavirus (HPV) seroprevalence and HPV type distribution in women with normal cervical cytology were studied. Cervical smear samples obtained using liquid-based smears from 582 clinically healthy women aged between 15 and 68 years from five centers from four different regions of Turkey, were studied between February 2010 and January 2011. Overall, 530 of the women with normal cytology were included and the samples were analyzed for the presence of HPV by AmpliTaq. Positive samples were typed further for 37 different HPV genotypes by a line blot assay. HPV was positive in 17.9% of the women. HPV prevalence was highest in the age group of 2529 years (31.8%), and decreased with increasing age. HPV 16 was the most common type (3.6%) followed by type 6 (2.6%) and type 45 (2.2%). Types 11 and 18 were rare (0.6% and 0.4%, respectively). Among the risk factors, number of sexual partners and parity were positively correlated with HPV positivity. In the present study, a large number of sex partners and high parity increased the risk for HPV infection. The age-specific distribution of HPV in women with normal Pap smears did not show a U-shaped curve in contrast to European countries and the USA. J. Med. Virol. 84: 12421247, 2012.
