Determining the Impact of a Community-Based Intervention on Knowledge Gained and Attitudes Towards the HPV Vaccine in Virginia

A Systematic Review of Human Papillomavirus Vaccination Challenges and Strategies to Enhance Uptake

Human papillomavirus (HPV) vaccination has revolutionized cervical cancer prevention. Clinical trials confirm that the quadrivalent (HPV types 6, 11, 16, 18) and bivalent (HPV types 16, 18) vaccines effectively prevent HPV infections and cervical neoplasia. The latest HPV vaccine protects against nine virus types responsible for 90% of cervical cancer cases globally. Despite their undoubted effectiveness in reducing morbidity and mortality associated with HPV infections, challenges in vaccine coverage and uptake persist. The current study aimed to identify the primary challenges associated with HPV vaccination, propose effective strategies to improve vaccination uptake, and compile relevant evidence into a comprehensive overview to inform policy and practice. A systematic review protocol, following PRISMA-P and PRISMA guidelines, was established. Articles were sourced from the Web of Science using keywords from a comprehensive review of HPV vaccination challenges and strategies. Studies published between 1 January 2020, and 1 May 2024, including RCTs and observational, qualitative, and cross-sectional studies, were included, while reviews, protocols, and commentaries were excluded. Titles, abstracts, and full texts were screened per PRISMA guidelines. The review identified five key strategies to improve HPV vaccination uptake: parental and school engagement, use of technology and multimedia tools, healthcare providers' role, multicomponent interventions, and targeted interventions for immigrant groups. This review emphasized the need for a multifaceted approach to improving vaccination rates, offering a robust foundation for policy and stakeholder initiatives.

Human Papillomavirus Awareness by Educational Level and by Race and Ethnicity

Importance

Understanding disparities in human papillomavirus (HPV) awareness is crucial, given its association with vaccine uptake.

Objective

To investigate differences in HPV awareness by educational attainment, race, ethnicity, and their intersectionality.

Design, Setting, and Participants

This 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 Measures

Weighted 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.

Results

A 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 Relevance

Disparities 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.

Overcoming barriers to HPV vaccination in rural Vermont through a multicomponent peer-based approach

Human Papillomavirus (HPV) causes almost all cervical cancers and many cancers of the anus, vagina, vulva, penis, and oropharynx. The HPV vaccine provides protection to all adolescents from a broad spectrum of cancers, yet HPV vaccination rates remain lower than those of other routine vaccines. Developing effective HPV vaccine interventions is particularly important in rural areas, whose residents have lower rates of HPV vaccination and higher cervical cancer incidence and mortality; however, interventional research in these populations is relatively limited. Furthermore, though rural areas are heterogeneous in many regards, few interventions engage stakeholders to develop community-specific solutions to overcome obstacles associated with HPV vaccination. Based on a review of existing literature, we recommend a multicomponent peer-based approach that includes school-based vaccination and awareness, parental involvement, and stakeholder engagement to increase HPV vaccination in rural areas, and we provide an example of such an intervention in rural Vermont.
