Effect of an HPV Vaccination Multi-Level, Multi-Component Program on HPV Vaccination Initiation and Completion in a Pediatric Clinic Network

Despite clear evidence of the public health benefits of the human papillomavirus (HPV) vaccine in preventing HPV-related cancers and genital warts, underutilization of HPV vaccination in the United States persists. Interventions targeting multi-level determinants of vaccination behavior are crucial for improving HPV vaccination rates. The study’s purpose was to implement and evaluate the adapted Adolescent Vaccination Program (AVP), a clinic-based, multi-level, multi-component intervention aimed at increasing HPV vaccine initiation and completion rates in a five-clinic pediatric network in Bexar County, Texas. The adaptation process was guided by established frameworks and involved formative work with clinic stakeholders. The study utilized a quasi-experimental single group pre- and post- study design, with an external comparison data using the National Immunization Survey-Teen (NIS-Teen) datasets for the same time period to examine the AVP’s effect on HPV vaccination initiation and completion. A series of interrupted time series analyses (ITSA) compared the clinic system patient outcomes (HPV vaccination initiation and completion rates) in the post-intervention to the general adolescent population (NIS-Teen). Of the 6438 patients (11–17 years) with clinic visits during the 3-year study period, HPV vaccination initiation rates increased from 64.7% to 80.2% (p < 0.05) and completion rates increased from 43.2% to 60.2% (p < 0.05). The AVP was effective across various demographic and economic subgroups, demonstrating its generalizability. ITSA findings indicated the AVP improved HPV vaccination initiation and completion rates in clinic settings and that AVP strategies facilitated resilience during the pandemic. The minimal adaptation required for implementation in a new clinic system underscores its feasibility and potential for widespread adoption.

Serum Proteomic Signatures in Cervical Cancer: Current Status and Future Directions.

In 2020, the World Health Organization (WHO) reported 604,000 new diagnoses of cervical cancer (CC) worldwide, and over 300,000 CC-related fatalities. The vast majority of CC cases are caused by persistent human papillomavirus (HPV) infections. HPV-related CC incidence and mortality rates have declined worldwide because of increased HPV vaccination and CC screening with the Papanicolaou test (PAP test). Despite these significant improvements, developing countries face difficulty implementing these programs, while developed nations are challenged with identifying HPV-independent cases. Molecular and proteomic information obtained from blood or tumor samples have a strong potential to provide information on malignancy progression and response to therapy in CC. There is a large amount of published biomarker data related to CC available but the extensive validation required by the FDA approval for clinical use is lacking. The ability of researchers to use the big data obtained from clinical studies and to draw meaningful relationships from these data are two obstacles that must be overcome for implementation into clinical practice. We report on identified multimarker panels of serum proteomic studies in CC for the past 5 years, the potential for modern computational biology efforts, and the utilization of nationwide biobanks to bridge the gap between multivariate protein signature development and the prediction of clinically relevant CC patient outcomes.

Policy Approaches for Increasing Adolescent HPV Vaccination Coverage: A Systematic Review.

US jurisdictions have enacted a wide range of policies to address low human papillomavirus (HPV) vaccination coverage among adolescents, but it is unclear which policies are effective. To systematically review the impact of governmental policies on adolescent HPV vaccination coverage. PubMed, Embase, and Scopus databases. Eligible studies, published from 2009 to 2022, evaluated the impact of governmental policies on HPV vaccination coverage among adolescents ages 9 to 18. Two investigators independently extracted data on study sample, study design and quality, policy characteristics, and HPV vaccination outcomes. We summarized findings by policy type: school-entry requirements (SERs), federally-funded policies related to the Vaccines for Children program and Medicaid, educational requirements, and others. Our search yielded 36 eligible studies. A majority of studies evaluating HPV vaccine SERs found positive associations between SERs and HPV vaccination coverage (8 of 14), particularly for SERs in Rhode Island and Washington, DC. All studies evaluating SERs for other adolescent vaccines observed positive spillover effects for HPV vaccination (7 of 7). Federally-funded policies related to Vaccines for Children and Medicaid were consistently associated with higher HPV vaccination coverage (7 of 9). Relatively few studies found associations between educational requirements and HPV vaccination coverage (2 of 8). Studies used limited vaccination data sources and non- or quasi-experimental designs. Some studies had no or poorly matched comparison groups. Our findings suggest promise for SERs and federally-funded policies, but not educational requirements, for increasing HPV vaccination coverage among adolescents.

"You Don't Know If It's the Truth or a Lie": Exploring Human Papillomavirus (HPV) Vaccine Hesitancy among Communities with Low HPV Vaccine Uptake in Northern California.

Vaccine hesitancy, delaying or refusing to vaccinate despite the availability of vaccines, impedes the progress of achieving optimal HPV vaccine coverage. Little is known about the sources of human papillomavirus (HPV) vaccine hesitancy among racially/ethnically and geographically diverse communities. The purpose of this paper is to explore HPV vaccine hesitancy among rural, Slavic, and Latino communities that reside in counties with low HPV vaccine uptake rates. Key informant interviews and focus groups were conducted with rural, Slavic, and Latino communities that reside within counties in California that have low HPV vaccine up to date rates (16-25%). Qualitative data were transcribed verbatim and analyzed using inductive and deductive thematic analysis. A total of seven focus groups and 14 key informant interviews were conducted with 39 individuals from seven California counties. Salient themes that contributed to HPV vaccine hesitancy included the following: social media and the anti-vaccination movement; a strong belief in acquiring immunity naturally; prior vaccine experiences; and vaccine timing concerns. Participants suggested the provision of culturally appropriate, in-language, in-person easy to understand HPV vaccine education to mitigate HPV vaccine hesitancy. Our findings can inform future interventions to increase HPV vaccine uptake among hesitant communities.

Individual and Geospatial Determinants of Health Associated With School-Based Human Papillomavirus Immunization in Alberta: Population-Based Cohort Study.

Human papillomavirus (HPV) infection causes nearly all cervical cancer cases and is a cause of anogenital and oropharyngeal cancers. The incidence of HPV-associated cancers is inequitable, with an increased burden on marginalized groups in high-income countries. Understanding how immunization status varies by material and social deprivation, health system, and geospatial factors is valuable for prioritizing and planning HPV immunization interventions. The objective of this study was to describe school-based HPV immunization rates by individual and geospatial determinants of health in Alberta, Canada. Health administrative data for male and female individuals born in 2004 in Alberta were used to determine HPV immunization status based on age and the number of doses administered in schools during the 2014/2015-2018/2019 school years. Immunization status and its relationship with material and social deprivation and health system factors were assessed by a logistic regression model. Geospatial clustering was assessed using Getis-Ord Gi* hot spot analysis. Mean scores of material and social deprivation and health system factors were compared between hot and cold spots without full HPV immunization using independent samples t tests. A multidisciplinary team comprising researchers and knowledge users formed a co-design team to design the study protocol and review the study results. The cohort consisted of 45,207 youths. In the adjusted model, the odds of those who did not see their general practitioner (GP) within 3 years before turning 10 years old and not being fully immunized were 1.965 times higher (95% CI 1.855-2.080) than those who did see their GP. The odds of health system users with health conditions and health system nonusers not being fully immunized were 1.092 (95% CI 1.006-1.185) and 1.831 (95% CI 1.678-1.998) times higher, respectively, than health system users without health conditions. The odds of those who lived in areas with the most material and social deprivation not being fully immunized were 1.287 (95% CI 1.200-1.381) and 1.099 (95% CI 1.029-1.174) times higher, respectively, than those who lived in areas with the least deprivation. The odds of those who lived in rural areas not being fully immunized were 1.428 times higher (95% CI 1.359-1.501) than those who lived in urban areas. Significant hot spot clusters of individuals without full HPV immunization exist in rural locations on the northern and eastern regions of Alberta. Hot spots had significantly worse mean material deprivation scores (P=.008) and fewer GP visits (P=.001) than cold spots. Findings suggest that material and social deprivation, health system access, and rural residency impact HPV immunization. Such factors should be considered by public health professionals in other jurisdictions and will be used by the Alberta co-design team when tailoring programs to increase HPV vaccine uptake in priority populations and regions.

HPV Vaccine Uptake, Willingness to Receive, and Causes of Vaccine Hesitancy: A National Study Conducted in Saudi Arabia Among Female Healthcare Professionals.

Epidemiological evidence has shown that human papillomavirus (HPV) is the most frequent cause of sexually transmitted infection, and vaccination is an essential measure to prevent associated diseases and complications. This study aimed to assess the HPV vaccine uptake and its associated factors as well as HPV vaccine hesitancy by female healthcare workers (HCWs) in Saudi Arabia. This online, questionnaire-based, cross-sectional study involved female HCWs in Saudi Arabia between July and October 2022. The study tool included questions about sociodemographic, occupational, and reproductive characteristics, uptake of HPV vaccination, and reasons of hesitancy. Chi-squared and t-tests were used for bivariate analyses, and multivariable logistic regression was used to adjust for confounders. The total number of participants was 1857. Around 20% of HCWs received at least one dose of the HPV vaccine, and around 45% were willing to take it this year. Lower odds of vaccine uptake were reported among older participants and those with a higher level of education. However, nurses, HCWs with a previous HPV infection, those with a family history of cervical cancer, or those with a previous cervical cancer screening test had higher odds of receiving the vaccine. On the other hand, older participants and diploma degree holders were less willing to take the HPV vaccine. Higher odds of willingness were reported in married HCWs, those with a previous HPV infection, those who received a previous HPV vaccine dose, or those who were screened for cervical cancer. Lack of knowledge and some misconceptions were the most reported reasons for hesitancy. Certain factors that affect HCWs personal decisions to take the vaccine were identified. By targeting these issues, epidemiologists, public health officialsand women's health care providers can work to increase HPV vaccine uptake and reduce the burden of HPV-related diseases in this population.

Exploring human papillomavirus vaccine hesitancy among college students and the potential of virtual reality technology to increase vaccine acceptance: a mixed-methods study.

Human papillomavirus (HPV) can cause cancers in men and women. Despite the availability of an effective vaccine, HPV vaccination coverage remains suboptimal among college students. Literature showed that hesitancy for HPV vaccination is a leading barrier to the uptake in this group. However, prior interventions have shown limitations in reducing HPV vaccine hesitancy in college students. Thus, this study examined a conventional educational approach using a vaccine information statement (VIS), and subsequently explored college students' HPV vaccine hesitancy and the potential of virtual reality (VR) technology to overcoming the limitations of interventional efforts. We employed a mixed-methods design along with convenience sampling, constituting a one-way pre- and post-intervention (HPV VIS) survey (Study A) and individual interviews (Study B). All data collections occurred with 44 college students at an urban public university at the mid-south region of the U.S. between October 2022 and April 2023. Study A assessed changes in HPV vaccination outcomes including knowledge, beliefs/attitudes, vaccine hesitancy, and intentions. Study B measured college students' primary reasons for HPV vaccine hesitancy and preferred strategies for the vaccination promotion including VR-based education. We conducted paired t-test and Wilcoxon signed ranks test for quantitative data and framework analysis for qualitative data. Participants reported significant improvements in knowledge [t(43) = 6.68, p < 0.001] regarding HPV vaccination between before and after reading the HPV VIS. No change was observed in beliefs/attitudes, vaccine hesitancy, and intentions. The framework analysis revealed college students' reasons for HPV vaccine hesitancy, needed information, and preferred strategies along with the potential of VR technology for future HPV vaccination education. The findings provided essential information on designing HPV vaccination information focused on vaccine hesitancy among college students. Future research should consider these findings in developing interventions including VR to increasing HPV vaccine acceptance among college students.

Immunogenicity of 2-Dose HPV Vaccine Series for Postpartum Women

Postpartum human papillomavirus (HPV) vaccination is a promising strategy to increase HPV vaccination uptake in the US, particularly for reaching vaccine-naive women and those who lack health insurance beyond the pregnancy period. However, completion of the 3-dose vaccine regimen is challenging. To evaluate the immunogenicity of a 2-dose postpartum HPV vaccination regimen (0 and 6 months) and assess whether it is noninferior to a 3-dose postpartum HPV vaccination regimen (0, 1-2, and 6 months) administered to historical controls. A noninferiority, open-label, nonrandomized immunogenicity trial was conducted from August 4, 2020, to June 23, 2022, of postpartum patients aged 15 to 45 years who delivered at 2 hospitals in Baltimore, Maryland. Historical controls were adolescents and young women aged 16 to 26 years. Two doses of the nonavalent HPV vaccine administered 6 months apart. The primary outcome was noninferiority (90% CI, lower bound >0.67) of the geometric mean titer (GMT) ratio for HPV-16 among postpartum women compared with historical controls. Secondary outcomes were noninferiority of GMT ratios for the other 8 HPV types and percentage seroconversion for each HPV type. As a noninferiority trial, the primary analysis used the per-protocol analysis. Of 225 enrolled participants, the mean (SD) age at baseline was 29.9 (6.8) years, and 171 (76.0%) were HPV-16 seronegative at baseline. Of these 171 participants, 129 (75.4%) received a second vaccine dose and completed the subsequent 4-week serologic measurements. Relative to historical controls, the HPV-16 GMT ratio was 2.29 (90% CI, 2.03-2.58). At month 7, HPV-16 GMT was higher after the 2-dose regimen (7213.1 mMU/mL [90% CI, 6245.0-8331.4 mMU/mL]) than among historic controls after the 3-dose regimen (3154.0 mMU/mL [90% CI, 2860.2-3478.0 mMU/mL]). Similarly, the lower bound of the 90% CI of the GMT ratio was above 1 for the 8 HPV types 6, 11, 18, 31, 33, 45, 52, and 58. A total of 118 of 134 women (88.1%) seroconverted for HPV-16 after the first dose; 4 weeks after the second dose, the seroconversion rate was 99% or greater for all HPV types. This study suggests that immunogenicity of a 2-dose HPV vaccination regimen given 6 months apart among postpartum women was noninferior to a 3-dose regimen among young historical controls. Most women seroconverted after the first dose of the 2-dose regimen. These results demonstrate that postpartum vaccination using a reduced schedule may be a promising strategy to increase HPV vaccine series completion. ClinicalTrials.gov Identifier: NCT04274153.

Human Papillomavirus Vaccination in Pediatric, Adolescent, and Young Adult Cancer Survivors-Opportunity to Address Gaps in Cancer Prevention and Survivorship.

The risks of secondary cancers associated with human papillomavirus (HPV) infection are as much as three times higher for survivors of pediatric, adolescent, and young adult cancer (PYAC) compared to the general population. Despite this, HPV vaccination rates among PYAC survivors remain low. Whereas pediatric oncology providers endorse HPV vaccination of PYAC survivors, many lack the resources or opportunities to intervene. The responsibility of HPV vaccination, therefore, falls to primary care providers and practices. This article provides an overview of the challenges with HPV vaccination that are distinct to PYAC survivors and discusses potential strategies to increase HPV vaccine coverage in this population.

Determinants of Human Papillomavirus Vaccine Acceptance among Caregivers in Nigeria: A Fogg Behavior Model-Based Approach.

Human papillomavirus (HPV) vaccine uptake among adolescent girls is critical to reducing the burden of HPV-related cancers in Nigeria. This study assesses the factors influencing caregivers' acceptance of HPV vaccination for their charges, using the Fogg Behavior Model (FBM) as a theoretical framework. We analyzed cross-sectional data from 1429 caregivers of girls aged 9-17 in six Nigerian states, using a survey instrument based on the FBM. Participants were recruited via Facebook and Instagram advertisements and interviewed through Facebook Messenger in August and September 2023. The study received ethical clearance from Nigeria's National Health Research Ethics Committee. We applied bivariate and multivariate analyses to assess the relationships between the caregiver's perception of how likely their adolescent girl was to get vaccinated in the next 12 months and motivation, ability, social factors (such as discussions with family and friends), injunctive norms, previous COVID-19 vaccination, and respondents' sociodemographic characteristics. Adjusted odds ratios derived from logistic regression analyses revealed that caregivers' motivation and ability, as well as social factors, were significantly associated with their perception that the adolescent girl in their care would get vaccinated within the next 12 months. Our findings suggest that behavioral interventions tailored to enhance motivation, ability, and social support among caregivers could significantly increase HPV vaccine uptake among adolescent girls in Nigeria.

The association of caregiver attitudes, information sources, and trust with HPV vaccine initiation among adolescents

ABSTRACT This study described caregiver attitudes and the information sources they access about HPV vaccination for adolescents and determined their influence on human papillomavirus (HPV) vaccination initiation. An online survey was administered to 1,016 adults in July 2021. Participants were eligible if they were the caregiver of a child aged 9–17 residing in Mississippi, Arkansas, Tennessee, Missouri, and select counties in Southern Illinois. Multivariate logistic regression was used to estimate the association of caregiver attitudes and information sources with HPV vaccination. Information from doctors or healthcare providers (87.4%) and internet sources other than social media (31.0%) were the most used sources for HPV vaccine information. The highest proportion of caregivers trusted their doctor or healthcare providers (92.4%) and family or friends (68.5%) as sources of information. The HPV vaccine series was more likely to be initiated in children whose caregivers agreed that the vaccine is beneficial (AOR = 4.39, 95% CI = 2.05, 9.39), but less likely with caregivers who were concerned about side effects (AOR = 0.61, 95% CI = 0.42, 0.88) and who received HPV vaccination information from family or friends (AOR = 0.57, 95% CI = 0.35, 0.93). This study found that caregivers’ attitudes, information sources, and trust in those sources were associated with their adolescent’s HPV vaccination status. These findings highlight the need to address attitudes and information sources and suggest that tailored interventions considering these factors could increase HPV vaccination rates.

Applying the COM-B behaviour model to understand factors which impact 15-16 year old students' ability to protect themselves against acquirement of Human Papilloma virus (HPV) in Northern Ireland, UK.

High-risk strains of Human Papillomavirus (HPV) can lead to the development of a number of cancers including cervical, vulvar, penile, anal and oropharyngeal. HPV vaccination programmes offer the HPV vaccine to males and females 12-13 years old in schools throughout the UK. However, knowledge of HPV remains low in post-primary schools. The aim of this study is to capture 15-16 year old students' perceptions regarding the current provision of HPV education, and whether providing HPV education to 15-16 year olds could influence their intention to be vaccinated and/or future sexual health decisions related to HPV. Between 5th November 2021 and 6th May 2022, seven focus groups were conducted with 34 students in post-primary schools in Northern Ireland, United Kingdom. The data was analysed using the COM-B behaviour model to explore the perceived facilitators and barriers impacting students' ability to protect themselves from acquirement of HPV. Students perceived their knowledge of HPV to be poor and supported the addition of comprehensive mandatory HPV education at 15-16 years old when many of them were becoming sexually active. They identified barriers including lack of parental education, school ethos and religion and insufficient education regarding their legal rights to self-consent to HPV vaccination. Students felt that removal of these barriers would lead to safer sexual practices, increased awareness of the importance of HPV screening and increased HPV vaccination uptake. The recommendations provided by students need to be supported by the Education Authority in conjunction with the Department of Health in order to be successfully implemented into the post-primary school curriculum.

Educational Interventions Planned to Increase Human Papillomavirus Vaccination Acceptance among Adolescents and Their Parents in Asia: A Systematic Literature Review

Abstract One of the Global strategies to accelerate the elimination of cervical cancer is vaccinated with HPV vaccines by age 15 years by 2030. Recent studies showed that increased vaccine-related knowledge associated with HPV-vaccine acceptance and intention to vaccinate. In other words, insufficient information is the main barriers to vaccination acceptance. Accordingly, interventions that improve understanding of HPV vaccines may increase HPV vaccination coverage. The aim of this study was to summarize educational interventions designed to increase HPV vaccine acceptance in adolescents and their parents. We searched the databases of PubMed, Science Direct and Google Scholar on October-December 2020. We performed a literature search for published articles in English and searched relevant keywords (papillomavirus vaccines and knowledge, acceptance, intervention studies, communication, education). Our search was limited to studies targeting populations from Asian countries. Thirteen interventional studies performed in Asian countries met the inclusion criteria. Five studies used PowerPoint presentation and slide presentation as an educational intervention. Two studies applied written media that was an educational sheet that provided information on HPV vaccines. Two studies used social media and mobile for educational intervention. Two studies designed the educational intervention in 30 minutes and 1 hour lecture which following by question and answer. Two of studies conducted two educational interventions. First one was applied PowerPoint presentation and social media and the second one used lecture and group discussion. HPV vaccine acceptance is varied widely between studies across Asian countries. Increasing public awareness about HPV vaccines, will increase acceptance. Increasing acceptance, will lead to demand people for health policy makers to will introduce HPV vaccines into their national immunization program.

Stories to Prevent Cancer: A Pilot Study Using Cancer Survivor Narratives to Increase Human Papillomavirus Vaccine Intentions.

Human papillomavirus (HPV) vaccination rates are lower than other recommended adolescent vaccines. Cancer survivor narratives are used to promote cancer prevention and control, but little is known about their impact on adolescent HPV vaccination. This pilot study explored the feasibility and effects of a video education intervention using a cancer survivor narrative to improve parents' attitudes toward and intentions to get the HPV vaccine. This study utilized a one-group design; participants completed a pre-intervention survey, watched the video before attending their sons' wellness visits, and completed a post-intervention survey within one week of their appointment. Using the narrative persuasion framework, we developed a 4-minute video of a local HPV-related cancer survivor to promote the HPV vaccine as cancer prevention. We recruited 37 participants between June and October 2020. Participants were parents of males ages 9-17 who had not yet initiated HPV vaccination. After the video, more parents agreed that HPV vaccination is safe (pre: 66% vs. post: 82%; P = .045) and that their child's chances of getting HPV-related cancer in the future are high (pre: 24% vs. post: 46%; P = .014). Overall, 91% of parents felt the cancer survivor story helped them understand the risks of HPV cancers, and 52% said the story influenced their decision to start HPV vaccination for their child. Our findings suggest that cancer survivor narratives influence parents' vaccine opinions and understanding of their child's risk of HPV infection, leading to increased parental intent to get the HPV vaccine for their adolescent males.

Urban and rural healthcare providers’ perspectives on HPV vaccination in Minnesota

ABSTRACT Human papillomavirus (HPV) vaccination can dramatically reduce the incidence of HPV-associated cancers. However, HPV vaccination coverage in rural areas is lower than in urban areas, and overall HPV vaccination coverage in the United States remains lower than other adolescent vaccines. We conducted 20 qualitative interviews with adolescent healthcare providers and clinic staff in urban and rural Minnesota and assessed their perspectives on HPV vaccination. Guiding interview topics included: strategies to persuade families to vaccinate their children, the impact of the patient-provider relationship and the clinical environment on vaccination uptake, and provider perceptions of parents’ vaccine attitudes. In thematic analysis, all participants reported using common vaccination strategies, such as framing the HPV vaccine in terms of cancer prevention. The analysis also revealed three themes described as occurring uniquely or more intensely in rural communities than urban communities: the rural value of choice or independence, the spread of misinformation, and close-knit, multifaceted patient-provider relationships in clinical practice. Interventions aimed at increasing HPV vaccination should consider the distinctive circumstances of rural healthcare providers and patients.

Abstract A036: The role of multisectoral partnerships in the dissemination of HPV vaccination campaigns in Puerto Rico

Abstract INTRODUCTION: The Human Papillomavirus (HPV) is the most common sexually transmitted infection worldwide. Despite the availability of an effective vaccine, HPV vaccination uptake is suboptimal in Puerto Rico (PR). Knowledge and understanding of the benefits of HPV vaccination can influence the intention to vaccinate. The Puerto Rico Community Cancer Control Outreach Program (PRCCCOP) and our network of multisectoral partners disseminated an HPV vaccination educational campaign tailored to promote HPV vaccination among kids and adolescents aged 9-26. OBJECTIVE: To effectively disseminate Human Papillomavirus (HPV) prevention educational campaigns through a network of multisectoral collaborators to increase HPV vaccination uptake in PR. METHODS: The PRCCCOP trained collaborators on basic HPV, HPV-caused cancers, and HPV vaccine knowledge and the use of educational materials. Collaborators distributed educational materials to their clientele who visited in person, participated in sponsored events, and accessed their virtual platforms or via email. In addition to printable educational materials, PRCCOP public service announcement videos about HPV vaccination were transmitted at our participating Federally Qualified Health Centers (FQHC). The PRCCOP provided all collaborators with continued training, assistance, and educational materials. RESULTS: Our program impacted 65 municipalities (83.3% of the island). Electronic and printed versions of our educational materials were disseminated in 40 clinics and vaccination centers across the island, including all 22 FQHCs in Puerto Rico (PR). Over 2,000 people were reached via in-person events and health fairs. Additionally, 18 workshops were imparted in clinical and academic settings. CONCLUSION: Community outreach can be an expensive and labor-intensive task. By establishing partnerships and sharing resources, the PRCCCOP has lowered costs while widely disseminating its educational campaigns and expanding its network outside the traditional academic/health services arena. Collaborating with multisectoral organizations allowed us to increase our presence throughout the island, diversify the types of dissemination mediums, and reach vulnerable and hard-to-reach populations.

Assessing Barriers to Human Papillomavirus (HPV) Vaccination in At-Risk Rural Communities of Western North Carolina, United States.

Human papillomavirus (HPV) vaccination among adolescents in rural, western North Carolina (NC) remains suboptimal. Data are needed to understand the barriers to HPV vaccination in these communities. We conducted a cross-sectional pilot study of parental attitudes and provider practices regarding HPV vaccination in rural western NC counties with lower HPV vaccination rates. Eight health department clinics were enrolled in the study. Further, 29 provider and 32 parent surveys were analyzed along with environmental scans. Median provider comfort regarding knowledge of HPV-associated diseases was 85% (IQR = 75-95), on a scale of 0-100% (100% representing complete comfort). Median parental comfort level regarding knowledge of HPV-associated diseases and the HPV vaccine was 75% (IQR = 50-89) and 75% (IQR = 49-96), respectively. Less than 25% of parents rated the HPV vaccine as 'extremely effective' against genital (16.7%) and anal cancers (17.9%). Parents were more likely to rate the vaccine as 'extremely effective' to 'very effective' if their child was female. There was no significant difference between parental- and provider-reported comfort with knowledge about HPV-associated diseases (p = 0.0725) and the HPV vaccine (p = 0.167). This study identified multiple opportunities to increase HPV vaccine coverage among unvaccinated adolescents at parental, provider, and clinic levels. Health education of rural NC residents and providers in public health settings may identify future interventions to increase HPV vaccine uptake.

Human Papillomavirus Awareness by Educational Level and by Race and Ethnicity

ImportanceUnderstanding disparities in human papillomavirus (HPV) awareness is crucial, given its association with vaccine uptake.ObjectiveTo investigate differences in HPV awareness by educational attainment, race, ethnicity, and their intersectionality.Design, Setting, and ParticipantsThis cross-sectional study used the Health Information National Trends Survey (HINTS) 5 cycles 1 to 4 data (January 26, 2017, to June 15, 2020). The data were analyzed from December 12, 2022, to June 20, 2023. A sample of the noninstitutionalized civilian US population 18 years or older was included in the analysis.Main Outcomes and MeasuresWeighted prevalence of HPV awareness, HPV vaccine awareness, and knowledge that HPV causes cancer, stratified by educational attainment and by race and ethnicity. Interaction between educational attainment and race and ethnicity was assessed using a Wald test.ResultsA total of 15 637 participants had educational attainment data available; of these, 51.2% were women, and the median age was 58 (IQR, 44-69) years. A total of 14 444 participants had race and ethnicity information available; of these, 4.6% were Asian, 13.9% were Black, 15.3% were Hispanic, 62.6% were White, and 3.6% were of other race or ethnicity (including American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, and more than 1 race or ethnicity). Awareness of HPV by educational attainment ranged from 40.4% for less than high school to 78.2% for college or higher; awareness by race and ethnicity ranged from 46.9% among Asian individuals to 70.2% among White individuals. Awareness of HPV vaccines across educational attainment ranged from 34.7% among those with less than high school to 74.7% among those with a college degree or higher and by race and ethnicity from 48.4% among Asian individuals to 68.2% among White individuals. Among adults who were aware of HPV, knowledge that HPV causes cervical cancer differed by educational attainment, ranging from 51.7% among those with less than high school to 84.7% among those with a college degree or higher, and by race and ethnicity, ranging from 66.0% among Black individuals to 77.9% among Asian individuals. The interaction between educational attainment and race and ethnicity on HPV awareness and HPV vaccine awareness was not significant; however, within each educational attainment level, awareness differed by race and ethnicity, with the lowest awareness consistently among Asian individuals regardless of educational attainment. Within each racial and ethnic group, HPV awareness and HPV vaccine awareness significantly decreased with decreasing educational attainment.Conclusions and RelevanceDisparities in HPV awareness were evident across social factors, with the lowest awareness among Asian individuals and individuals with lower educational attainment. These results emphasize the importance of considering social factors in HPV awareness campaigns to increase HPV vaccination.

A qualitative study of ethnic Korean women and men's experiences of HPV and HPV vaccination in the United States

ABSTRACT Introduction Approximately 42.5% of adults aged 18–59 in the United States is estimated to be affected by human papillomavirus (HPV) infection. However, Asian Americans have the lowest HPV vaccination initiation rate compared to other racial groups. This study aims to explore the experiences of HPV and the HPV vaccination among ethnic Korean women and men in the United States. Methods A total of 33 ethnic Korean and Korean Americans aged 27–45 years living in the U.S. were recruited via word-of-mouth and social media using a purposive sampling strategy. They participated in an online survey. Of the 33 participants, 29 (14 females and 15 males) participated in in-depth interviews via password-protected Zoom. A content analysis approach was used to analyze the interviews. Results Only 32% of participants had received the HPV vaccine at least once (female: 35.3%, male: 12.5%). Six major themes emerged from data analysis: (1) awareness of HPV, HPV vaccine, and HPV-associated cancers; (2) attitudes toward the HPV vaccine; (3) barriers to HPV vaccination; (4) women's experiences and preferences for pap smear testing; (5) experiences with HPV diagnosis; and (6) HPV and HPV vaccination education preferences. Conclusion The findings highlight cultural factors that may impede the discussion about and uptake of HPV vaccination and HPV-associated cancer screening, which emphasize the need for culturally appropriate interventions to overcome stigma around HPV and enhance vaccination rates. Healthcare providers should consider ethnic and cross-cultural differences perceptions to effectively HPV-related health information. This study provides insight into the experiences and understanding of HPV and vaccination among ethnic Korean men and women, laying the groundwork for developing culturally-tailored programs that sim to increase HPV vaccination rates and mitigate the stigma and impact of HPV-related disease in this community.

Self-reported HPV vaccination status and HPV vaccine hesitancy in a nationally representative sample of emerging adults in Croatia.

The aim of this study was to determine self-reported human papillomavirus (HPV) vaccination status among emerging adults in Croatia, intention to get the HPV vaccine among unvaccinated individuals and correlates of HPV vaccine hesitancy. Data were collected via a cross-sectional survey based on a probabilistic national sample. The sample included 1,197 individuals aged 18-25 years (50.6% were women) who were recruited from November 2021 to February 2022 as part of the commercial online panel. Analyses included 981 participants who correctly answered two "attention trap" questions using descriptive statistics and multivariate analyses. The data were post-hoc weighted for gender and age and adjusted for clustering effect. To adjust standard errors for the sampling design, multivariate analyses were carried out using the complex samples module in the IBM SPSS 27 statistical software package. Overall, 18.3% of participants (25.0% of women and 11.7% of men) reported that they were HPV vaccinated, while 21.9% did not know their HPV vaccination status. Of those vaccinated, 65.6% were women. The odds of being HPV-vaccinated were significantly higher among female participants. Among the unvaccinated, 35.4% expressed a willingness to get the vaccine. The odds of vaccination hesitancy were significantly lower among women, participants who reported a higher perceived risk of STIs, those who recognized that HPV could result in cervical cancer, and significantly higher among those who were more religious. Our findings suggest a need to increase HPV vaccination uptake in Croatia through raising awareness about HPV vaccine effectiveness and also through the implementation of strategies to make vaccination more available.
