A. Prevalence of Low-Risk and High-Risk Types by Age (n = 2065).

<p>Prevalence of overall and both hr- and lr-HPV types showed an almost similar age-distribution. In some women both low-risk and high-risk types were detected. B. Prevalence of Low-Risk and High-Risk Types by Sexual Age (n = 1943). Only sexually active women were selected (n = 1943). Overall HPV prevalence, as well as hr- and lr-HPV prevalence, showed an increase with rising sexual age. However, hr-HPV prevalence decreased from a sexual age of 10 years. In some women both low-risk and high-risk types were detected.</p

A. Prevalence High-Risk HPV Types.

<p>Most common types detected were HPV type 16 (2.8%, n = 57), HPV type 51 (2.5%, n = 51), and HPV type 52 (2.5%, n = 52). In some women both low-risk and high-risk types were detected. B. Prevalence Low-Risk HPV Types. In some women both low-risk and high-risk types were detected. HPV genotype 53 and 66 can also be considered as possible high risk types.</p

95% Confidence Interval of HPV Prevalence by Age (n = 2065).

<p>There was an overall increase in HPV prevalence with age till 22 years, afterwards a plateau phase was reached. A decrease is shown at 23 years and a peak among women aged 27 years, however, as the 95% confidence interval is overlapping with adjacent age groups, the differences were considered accidental findings.</p
