Abstract

Background: The prevalence of high-risk genotypes of the human papillomavirus (HR-HPV) in Galicia remained unknown before the introduction of the HPV vaccine. The objective of this study was to estimate this prevalence in non-vaccinated women when vaccination against HR-HPV started. Sample representativeness was also evaluated.

Methods: Female volunteers aged 16-64 years, residents in Galicia, Spain, completed a questionnaire and provided biological samples for a virological study and for cytology. The sample was weighted; prevalence rates were estimated and are shown with 95% confidence intervals.

Results: Virological results were available for 1703 women. HR-HPV prevalence was 10.1%, decreasing notably at ages above 30 years. HPV-16 was the most frequent genotype and 3.6% of women were infected by more than one genotype. No adjustment was necessary to generalize the results of the study.

Conclusions: In Galicia in 2009 there would be 96 400 women aged 16-64 years infected with HR-HPV. It is possible to estimate HR-HPV prevalence in a population starting from a volunteer sample.

高危人乳头瘤病毒在加利西亚,西班牙:患病率和样本代表性的评价。
背景:在引入HPV疫苗之前,加利西亚人乳头瘤病毒(HR-HPV)高危基因型的流行率仍然未知。本研究的目的是估计当开始接种HR-HPV疫苗时,未接种疫苗的妇女的患病率。并对样本的代表性进行了评价。方法:年龄16-64岁的西班牙加利西亚居民女性志愿者完成了一份调查问卷,并提供了用于病毒学研究和细胞学研究的生物样本。对样本进行加权;对患病率进行估计,并以95%置信区间显示。结果:1703例妇女获得病毒学结果。HR-HPV患病率为10.1%,在30岁以上年龄组明显下降。HPV-16是最常见的基因型,3.6%的妇女感染了一种以上的基因型。不需要调整来概括研究结果。结论:2009年加利西亚16-64岁女性感染HR-HPV为96 400例。可以从志愿者样本开始估计人群中的HR-HPV患病率。
