Almost all cervical cancers are causally related to infections by human papillomavirus (HPV), with HPV types 16 and 18 responsible for ~70% of this malignancy. American Indian (Al) women have one of the highest incidences of cervical cancer among U.S. women, and this rate is increasing. Al women also have the poorest cervical cancer survival of any racial/ethnic group. Reasons for the high incidence, poor survival, and variation by tribe are unknown, but might be explained by lower rates of Papanicolaou (Pap) screening, a higher prevalence of oncogenic HPV infection,15 or a higher prevalence of particularly virulent HPV 16 or HPV 18 variant. We found that the prevalence of high-risk HPV types in Al women was over twice that in White women. After adjusting for age and abnormal Pap results, the odds ratio of high-risk HPV infection in Al versus White women was 2.9 and Al women were 4 times more likely to have an abnormal Pap test. In this Research Project, we propose to partner with the Hopi Tribe in Arizona to conduct 2 theoretically linked studies, designed to complement one another and cover the lifespan of HPV prevention and screening. The first study aims to increase HPV vaccination rates among girls aged 11-12 years by engaging motherdaughter dyads. The second study examines the presence of high-risk HPV types and variants, particularly HPV 16 and 18, in Hopi women. Our specific aims in Study 1 are to 1) Compare the number of Hopi girls ages 11-12 receiving HPV vaccination before and after a 2-year implementation of our mother-daughter educational intervention; and 2) Assess individual predictors of HPV vaccination. In Study 2 we aim to 2): compare the prevalence of high-risk HPV types in Hopi women adherent with cervical cancer screening guidelines to those who are non-adherent; and 4) Compare risk and protective factors for high-risk HPV infection among screening adherent and non-adherent Hopi women. We hypothesize that screening nonadherent women will have more high risk HPV types, more risk factors, and fewer protective factors than those who are adherent. This study fits into the multi-level health disparities model by examining how individual, family, and organizational variables influence cervical cancer prevention among Hopi women and young adolescents.

几乎所有的宫颈癌都与人乳头瘤病毒（HPV）感染有关，其中HPV 16和18型占这种恶性肿瘤的约70%。美国印第安人（Al）妇女是美国妇女中宫颈癌发病率最高的人之一，而且这一比例正在上升。在所有种族/族裔群体中，妇女的宫颈癌生存率最低。发病率高、生存率低和部落差异的原因尚不清楚，但可能是由于巴氏（Pap）筛查率较低、致癌HPV感染的患病率较高、特别强毒的HPV 16或HPV 18变异体的患病率较高。我们发现，高危型HPV的流行率在Al妇女是两倍以上，在白色妇女。校正年龄和异常巴氏试验结果后，高危型HPV感染的优势比在铝与白色妇女是2.9和铝妇女有4倍以上的可能性异常巴氏试验。在 在这个研究项目中，我们建议与亚利桑那州的霍皮部落合作，进行两项理论上相关的研究，旨在相互补充，并涵盖HPV预防和筛查的寿命。第一项研究的目的是通过让母女二人组参与，提高11-12岁女孩的HPV疫苗接种率。第二项研究检查了霍皮族妇女中高危HPV类型和变体的存在，特别是HPV 16和18。我们在研究1中的具体目标是：1）比较11-12岁霍皮族女孩在实施母女教育干预2年前后接受HPV疫苗接种的人数; 2）评估HPV疫苗接种的个体预测因素。在研究2中，我们的目标是2）：比较遵守宫颈癌筛查指南的霍皮族妇女与未遵守者的高危HPV类型的患病率;和4）比较筛查遵守者和未遵守者霍皮族妇女中高危HPV感染的风险和保护因素。我们假设，筛查不依从的妇女将有更多的高危HPV类型，更多的危险因素，和更少的保护因素比那些谁是坚持。本研究通过研究个人、家庭和组织变量如何影响霍皮族妇女和青少年的宫颈癌预防，符合多水平健康差异模型。
