Abstract PO-274: Human papillomavirus vaccination rates and knowledge among Latinx women in East Los Angeles

Background:Women with autoimmune inflammatory rheumatic diseases (AIIRDs) may be more vulnerable to human papillomavirus (HPV) infection and HPV-related cervical cancers [1,2]. However, the HPV test and HPV vaccination rate was...

Background: Human papillomavirus (HPV) is the most common sexually transmitted infection, with estimates for the probability of infection with the virus exceeding 80% for women and 90% for males across their lifetime. People with HIV (PWH) are at a higher risk of acquiring oral HPV infection, despite antiretroviral therapy, making them more susceptible to Oropharyngeal cancer (OPC). Puerto Rico (PR) has a significant burden and disparity of HPV and HIV-related malignancies, and socio-economic disadvantages, which limit access to HPV vaccine. While HPV vaccination rates in the US is 46% in young adults, HPV vaccination rates in PR are limited, particularly in PWH. Here, we described the prevalence of oral HPV infection among PWH in PR and investigated socio-behavioral factors associated with HPV infection. Methods: We evaluated 135 sexually active PWH with a median age of 48 years old. Oral rinse samples were collected and analyzed for HPV and genotyped using the DNA ELISA kit HPV SPF10 and RHA kit HPV SPF10-LiPA25. An administered questionnaire collected sociodemographic characteristics and lifestyle variables. Statistical analyses were performed in R-statistical software. Results: There was a 32% prevalence of oral HPV infection, of which 61% were high-risk genotypes, with HPV-18 being the most abundant (39%). The prevalence of oral HPV was higher in males than females (34% vs. 17%), and high-risk genotypes were only present in males. High proportion of our cohort (67%) did not have the HPV vaccine while 60% have the knowledge of HPV infection. Knowledge of HPV infection was higher in males than females (56% vs 33%), but even then, vaccination rates were very low (20% males vs 11% females). Conclusion: High prevalence of oral HPV infection was observed in PWH, higher than previously observed in PR. Limited HPV vaccination rates may possibly be due to age ineligibility, access, or lack of awareness of the vaccine. Males had a higher prevalence of oral HPV infection and were the group in which high-risk HPV genotypes were detected. Although female vaccination rates were low, the lack of high-risk genotypes may be due to early access to HPV vaccine based on regular established screening protocols for cervical cancer, but these protocols have not been established for high HPV-related cancer risk male populations. The incidence in OPC is increasing and it is expected to exceed that of cervical cancer, these findings highlight the need to establish better preventive public health strategies from an educational standpoint, and medical care access.

Background: Despite having guidelines recommending vaccination against the human papillomavirus (HPV) and widespread coverage for the vaccine, HPV vaccination rates among U.S. Hispanic and island Puerto Rican (PR) girls are low. In 2012, only 16% of PR girls aged 11–18 and 42% of U.S. Hispanic girls aged 13-17 were vaccinated with all three HPV vaccine doses; far fewer than the Healthy People 2020 goal of 80%. Parents are crucial to the success of HPV vaccine uptake efforts. Few studies focusing on parents have examined possible differences in HPV knowledge and vaccine acceptability within ethnic groups. The purpose of the study is to assess potential differences in HPV knowledge, vaccine awareness, and acceptability between U.S. Hispanic and island PR women. Methods: We utilized data from the Health Information National Trends Survey (HINTS) 2007 and HINTS Puerto Rico 2009. For the current study, we restricted our analyses to female respondents in both surveys for a total sample of 792 women (n = 375; U.S. Hispanic HINTS 2007 and n = 417; Puerto Rican HINTS-PR 2009). Using the Wald chi-square test, we assessed if there were significant differences in HPV knowledge, vaccine awareness, and acceptability between U.S. Hispanics and island PR women. Results: Island PR women had significantly higher HPV vaccine awareness (66.9% vs. 61.0%; Wald X2 F(1, 97) = 16.03, p < .001) and were more accepting of the HPV vaccine for a real or hypothetical daughter (74.8% vs. 56.1%; Wald X2 F(2, 96) = 7.18, p < .001) compared to U.S. Hispanic women. Both groups were highly knowledgeable that HPV causes cancer (89.2% in both samples) and HPV is a sexually transmitted infection (78.1% [U.S. Hispanics] and 84.7% [PR]). Less than 10% of both groups recognized that HPV can go away on its own without treatment. Conclusions: Our study found that island PR women were more aware of and accepting of the HPV vaccine when compared to U.S. Hispanic women. Future research should further explore these in-group differences to determine what in the PR socio-cultural context or environment may have led to higher HPV vaccine awareness and acceptability. Findings may also assist in developing culturally appropriate health education programs and media to promote HPV vaccination among both groups. Citation Format: Daisy Y. Morales-Campos, Robin C.

HPV vaccination rates remain low: cancer prevention community needs to continue promoting the vaccine's safety and efficacy, say experts.

Human Papillomavirus and Vaccination

Background: The human papillomavirus (HPV) virus is a known pathogen and carcinogen causing deadly cancers of the genitalia and head and neck. The HPV vaccine is a safe, effective cancer-preventing vaccine recommended for girls and boys at ages 11-12. Full HPV vaccine coverage is available through health insurance plans and the state of California, yet no data were readily available to describe California state-wide coverage of HPV vaccination. The Data Workgroup of the California HPV Vaccination Roundtable aimed to map State-level HPV vaccine coverage. Methods: Workgroup collected, analyzed, and mapped 2018 HPV vaccination data from the NIS-T survey, quality performance metrics from public and private health plans, and the statewide CAIR. NIS-T provides state-level estimates of routine adolescent vaccines, including HPV. Performance data were obtained from Medi-Cal and commercial health plans, administrative claims, and medical records. CAIR contains individual-level, provider-reported immunizations. HPV vaccination coverage for adolescents were estimated at the state and county level. Maps of county-level HPV vaccination and HPV-related cancer rates were built. Results: Rates of HPV-related cancers ranged from 6-12 per 100,000. Regarding HPV vaccination, there were considerable variation in the metrics and limitations of each data source, therefore estimates are not easily comparable. CAIR estimates of HPV vaccination coverage (28%) are lower than those for Medi-Cal managed care (45%) and commercial HMO members (50%). In 2018, aggregated results showed that overall 50% of 13 year old were vaccinated. We observed in the CAIR data that boys and girls are vaccinated at similar rates. However, significant county/regional HPV vaccination rates exist ranging from 9% (rural, northern) to 55% (urban, western). Northern, rural country have both the lowest HPV vaccination completion rates for 13-year-olds (9%), and the highest HPV-attributable cancer rates in the state (12 cases per 100,000 persons. Race/ethnic variations exist for HPV vaccination and HPV- related cancers–especially cervical cancer. Conclusions: This state-level data report approach may facilitate practice and policy action and help other states in developing their own reports for HPV vaccine improvements. Stakeholders are encouraged to utilize this Report when planning HPV vaccination interventions. We recommend that health systems: 1) assess HPV vaccination rates for 13-year-olds, 2) establish data exchange with CAIR, 3) implement recommended strategies to improve coverage, 4) collaborate with health plans and clinicians and 5) partner with community advocacy groups and clinic/hospital parent/patient advisory groups to improve data accuracy, as well as reduce HPV vaccine hesitance and promote at least 80% HPV vaccination completion by 2026.

Background: the distribution of human papillomavirus (HPV) infection, vaccination rates, and awareness levels varies across China. Methods: this study examined HPV infection prevalence, vaccine uptake, and barriers among 2440 women aged 30–64 in Shenzhen, China, using partial least squares structural equation modeling (PLS-SEM) to analyze associated factors. Results: The overall HPV prevalence was 14.2% (347/2440), with HPV52 being the most common type, followed by HPV58 and HPV53. Factors significantly associated with HPV infection included more sexual partners, genital tract infections, manual labor, and single marital status (p < 0.05), whereas higher education demonstrated a protective association (p < 0.05). The HPV vaccination rate was 41.8% in ages 30–45. There were direct effect indicators of younger age, fewer pregnancies, and premenopausal status (p < 0.05) on HPV vaccine uptake, whereas inversely associated factors included divorce/widowed, lower household income, irregular menstruation, more deliveries, no contraception, and lack of HPV knowledge. Among 828 unvaccinated individuals, 47.9% of those aged 46–64 were willing if the age restrictions were expanded, with the main barrier being a lack of vaccine knowledge (40.7%). Willingness was significantly associated with younger age and healthcare occupation (p < 0.05), but negatively with eastern Shenzhen residence, lower household income, no HPV disease awareness, abnormal leucorrhea, lack of HPV knowledge, and belief against post-vaccination screening (p < 0.05). Conclusions: Socioeconomic disparities in HPV infection and vaccination rates in Shenzhen highlight intervention priorities. The impact of HPV knowledge underscores the need for effective health communication. The vaccination willingness and infection status among women aged 45+ provide supporting evidence for expanding HPV vaccination to older age groups.

Vaccinating Adolescents—New Evidence of Challenges and Opportunities

Same-day human papilloma virus vaccination improves vaccine uptake in a dermatology sexually transmitted infection clinic: A quality improvement-based model for improving vaccination rates.

Background: Human papillomavirus (HPV) vaccination rates in the United States remain low and lag behind other recommended adolescent vaccines. Studies evaluating the association of geographic and area-level characteristics with HPV vaccination rates provide a valuable resource for public health planning.Method: We used the Rochester Epidemiology Project data linkage system to ascertain HPV vaccination rates between 2010 and 2015 in a 7-county region of southern Minnesota. Geocoded individual patient data were spatially linked to socioeconomic data from the American Community Survey at the census block group level. Bayesian hierarchical logistic regression was used to model incident vaccination rates, adjusting for individual- and area-level sociodemographic characteristics, and geolocation. Geolocation was modeled as an approximated Gaussian field using a Stochastic Partial Differential Equations approach. All models were estimated using Integrated Nested Laplace Approximations.Results: In adjusted models, increasing age and female sex were associated with increased HPV vaccination. Lower socioeconomic status was associated with decreased rates of initiation [adjusted odds ratio (AOR); 95% confidence interval = 0.90 (0.86-0.95)], completion of the second dose [AOR = 0.88 (0.83-0.93)], and completion of the third dose [AOR = 0.85 (0.80-0.92)]. Geographic spatial analysis demonstrated increased odds of vaccination for the eastern region and in the greater Rochester metropolitan area, showing significant spatial variation not explained by individual level characteristics and ACS block group-level data.Conclusions: HPV vaccination rates varied geographically and by individual and geographically indexed sociodemographic characteristics.Impact: Identifying geographic regions with low HPV vaccination rates can help target clinical and community efforts to improve vaccination rates.

In the United States, uptake of human papillomavirus (HPV) vaccination has been exceptionally low as compared with other vaccines. During the coronavirus disease (COVID-19) pandemic, routine vaccinations were deferred or delayed, further exacerbating HPV vaccine hesitancy. The specific effect of the pandemic on HPV vaccination rates in the United States has not been yet described. We aimed to determine the percentage of children achieving full HPV vaccination (2 doses) by age 15 years and to compare prepandemic to pandemic rates of HPV vaccination at pediatric practices across our institution. A retrospective chart review was performed to compare HPV vaccination rates in the "prepandemic" and "pandemic" periods for all children 9 through 14 years of age. Additionally, peaks in COVID-19 positivity were compared with HPV vaccination rates. Of children aged 9-14 years, 49.3% received at least 1 dose of HPV vaccine in the prepandemic period, compared with 33.5% during the pandemic (P < 0.0001). Only 33.5% of patients received the full 2-dose series of HPV prepandemic, compared with 19.0% of patients during the pandemic (P < 0.0001). When COVID-19 positivity rates peaked, HPV vaccination also declined. The issue of low HPV vaccination rates was amplified due to the COVID-19 pandemic, as illustrated by the correlation between peaks in COVID-19 positivity and low rates of HPV vaccination.

Purpose: The purpose of this study is to determine the association between awareness of human papillomavirus (HPV), cervical cancer, and HPV vaccine and intention to vaccinate preteens and teens against HPV. Background: Genital human papillomavirus (HPV) is the most common sexually transmitted infection in the United States, and results in 14 million new cases each year. Around 50% of new HPV infections occur among persons aged 15-24 years old. Cervical cancer is primarily attributable to HPV, and the yearly cost of cervical cancer screening as well as treatment of HPV-related diseases is around $8 billion. In 2009, around 35,000 HPV-related cancers were reported in the United States. The level of coverage for 3 HPV vaccine doses for females aged 13-15 years was only 30% in 2011. This is far below the 80% target coverage level set by Healthy People 2020. The 2013 National Immunization Survey-Teen found that only 50% of Maryland females aged 13-17 years and only 34.2% of male adolescents reported beginning the HPV vaccine series. According to the 2013 Maryland Cancer Data, Maryland had the 25th highest cervical cancer mortality rate from 2006-2010. During these years, more black women were diagnosed with cervical cancer than White women, and their rate of cervical cancer incidence has been increasing at a rate of 4.9% more per year than white women. We investigate the relationship between HPV, cervical cancer, and HPV vaccine awareness and intention to vaccinate preteens and teens against HPV. Methods: Utilizing the principles of community-based participatory research (CBPR), the Johns Hopkins Center to Reduce Cancer Disparities, in collaboration with its Community Advisory Groups in Baltimore City and Prince George's County, developed and implemented a survey to assess the knowledge, awareness and behavioral intentions on cervical cancer, HPV and HPV vaccine. The study was approved by the Johns Hopkins School of Medicine's Institutional Review Board and implemented between March 2015 and July 2015 in Baltimore City and Prince George's County. Four hundred and three individuals recruited through community events completed the assessment. Upon completion of the assessment, participants were given feedback on their responses to address any knowledge gap and educational materials. Binary and multinomial logistic regression were used to determine the association between awareness of HPV, cervical cancer, and HPV vaccine and intention to vaccinate children between the ages of 11 and 18 years against HPV. Results: The majority of study participants were female (78%), black or African American (87%), have at least one year of college or technical school (55%) and have an annual household income of less $20,000 (38%). Awareness of the existing of HPV vaccine is significantly associated (OR=2.54, P&amp;lt;0.0007, CI 1.487-4.355) with the intention to vaccinate children against HPV. We also found that individuals who never heard of the HPV vaccine are significantly less likely (OR=0.394, p&amp;lt;0.0007, CI 0.230-0.673) to vaccinate their children against HPV than those who have heard of the vaccine. Furthermore, those who are aware of HPV are significantly more likely to know that HPV can cause cervical cancer (OR=5.25, P&amp;lt;0.0001, CI 3.272-8.454) and to know that HPV is transmitted through sexual contact (OR=3.66, P&amp;lt;0.0001, CI 2.199-6.100) compared to those who never heard of HPV. Conclusion: Awareness of HPV, cervical cancer, and HPV vaccine are significantly associated the intention to vaccinate children between the ages of 11 and 18 years against HPV. Increasing knowledge of cervical cancer and the importance of HPV vaccination among parents and caretakers of preteens and teens have the potential to increase the rates of HPV vaccination and prevent future cervical cancers. More research is needed to explore other factors that are related to HPV vaccination.

Introduction: Human Papillomavirus (HPV) is the most common sexually transmitted disease. The contraction of HPV is associated with the development of several different types of cancers, including anal, cervical, and oropharyngeal cancers. These cancers have proven to impact Black and Hispanic women disproportionately across the United States, suffering from high rates of HPV infection and high incidence of cervical cancer. Despite knowledge of this risk, HPV vaccination rates remain low among minority women. Personal beliefs and access surrounding HPV vaccination may be contributors to these disparities. This survey aims to study the motivations behind the choice to receive HPV vaccination among health science students. Health science students are the target for this study as they are uniquely situated as the future providers of their communities. If the study is able to gauge how they feel about HPV vaccination, then the scientific community can target interventions to impact change beginning with the providers themselves. Females specifically were chosen as they are the primary targets of HPV vaccination. HPV vaccination rates among female health science students are a secondary result. Methods: A 37-item electronic survey was sent out to female health science students at the University of Florida which include the schools of Dentistry, Medicine, Nursing, Pharmacy, Public Health, and Veterinary Science. The online survey was then distributed in July of 2021 through Qualtrics. The survey evaluated previous HPV knowledge, motivations for or against HPV vaccination, and beliefs surrounding HPV vaccination. Results: The survey was delivered and distributed in July of 2021. In this study there are four different types of questions analyzed to gather information on previous HPV knowledge, attitudes, beliefs and external influences. Results will be categorized and compared based on race/ethnicity. By analyzing these groups there is an opportunity to understand how one's racial or ethnic background can affect their medical decisions in health science students and the recommendations they give to others. Results are pending. Conclusion: This being the first study of its kind warrants further investigation as health science students are trusted individuals of the medical community. If these students are against HPV vaccination, then medical schools could target interventions to teach students about racial disparities in HPV infection and vaccination recommendation. So, when given the opportunity as a provider these students can recommend vaccination to their patients. These results are indicative of knowledge gaps and attitudes within the younger generations of the medical community. Citation Format: Katya M Marcia, John M Allen.
