An opportunity for cancer prevention during preadolescence and adolescence: stopping human papillomavirus (HPV)-related cancer through HPV vaccination

Awareness of HPV vaccine and its socio-demographic determinants among the parents of eligible daughters in Bangladesh: A nationwide study

Background

Vaccination against Human papillomavirus (HPV) is recommended to avoid HPV infections and its associated diseases, including cervical cancer. However, there is no awareness study among Bangladeshi population. Hence, this nationwide study was conducted to explore HPV vaccine awareness and its determinants among parents of eligible adolescent girls.

Methods

This study was conducted among the parents of daughters aged 9-15 years from 42 out of 64 randomly selected districts of Bangladesh between June 28 to August 2, 2023. A multistage sampling method was used to enroll 2151 study participants from all eight divisions of Bangladesh. A semi-structured questionnaire was used for face-to-face interviews in this study. The statistical software Stata (Version 17) was used for statistical analyses.

Results

The average age of the participants was 38.18 (±5.86) years. Only 22.32 % of the participants were aware of the HPV vaccine. Every additional year of age increased the likelihood of being aware of the HPV vaccine by 3 % (AOR: 1.03; 95%CI: 1.00-1.06). Participants residing in the urban area had 3.56 times higher odds of awareness than rural and semi-urban people. Businessmen and housewives had 60 % (AOR: 0.40; 95 % CI: 0.22-0.69) and 77 % (AOR: 0.23; 95 % CI: 0.16-0.33) lower odds in comparison to job holders. The lower-income group exhibited significantly higher odds of awareness (AOR: 0.25, 95%CI: 0.16-0.39) compared to the middle and the higher-income group. Participants who never went through routine health check-ups had 77 % lower odds of being aware than those who availed of regular routine check-ups (AOR: 0.23; 95%CI: 0.16-0.34).

Conclusion

Awareness of the HPV vaccine among the general population of Bangladesh is very low. Age, residence, occupation, monthly income, and routine medical check-ups were associated with HPV vaccine awareness. A nationwide awareness campaign would increase this awareness level among the Bangladeshi population, especially among the parents of daughters.

Facilitators and barriers of HPV vaccination: a qualitative study in rural Georgia

INTRODUCTION

Human papillomavirus (HPV) vaccination protects against HPV-associated cancers and genital warts. Healthy People 2030 goal for HPV vaccine uptake is 80%, but as of 2021, only 58.5% of adolescents are up to date in Georgia. The purpose of the study is to assess the attitudes, vaccine practices, facilitators, and barriers to receiving the HPV vaccine in southwest Georgia.

METHODS

We conducted 40 semi-structured interviews in the United States from May 2020-Feburary 2022 with three different audiences (young adults, parents, and providers and public health professionals) guided by the P3 (patient-, provider-, practice-levels) Model. The audiences were recruited by multiple methods including fliers, a community advisory board, Facebook ads, phone calls or emails to schools and health systems, and snowball sampling. Young adults and parents were interviewed to assess their perceived benefits, barriers, and susceptibility of the HPV vaccine. Providers and public health professionals were interviewed about facilitators and barriers of patients receiving the HPV vaccine in their communities. We used deductive coding approach using a structured codebook, two coders, analyses in MAXQDA, and matrices.

RESULTS

Out of the 40 interviews: 10 young adults, 20 parents, and 10 providers and public health professionals were interviewed. Emerging facilitator themes to increase the uptake of the HPV vaccine included existing knowledge (patient level) and community outreach, providers' approach to the HPV vaccine recommendations and use of educational materials in addition to counseling parents or young adults (provider level) and immunization reminders (practice level). Barrier themes were lack of knowledge around HPV and the HPV vaccine (patient level), need for strong provider recommendation and discussing the vaccine with patients (provider level), and limited patient reminders and health education information around HPV vaccination (practice level). Related to socio-ecology, the lack of transportation and culture of limited discussion about vaccination in rural communities and the lack of policies facilitating the uptake of the HPV vaccine (e.g., school mandates) were described as challenges.

CONCLUSION

These interviews revealed key themes around education, knowledge, importance of immunization reminders, and approaches to increasing the HPV vaccination in rural Georgia. This data can inform future interventions across all levels (patient, provider, practice, policy, etc.) to increase HPV vaccination rates in rural communities.

Relationship between religiosity and HPV vaccine initiation and intention in urban black and hispanic parents

OBJECTIVE

Religion is believed to be an important sociocultural influence in the U.S., but little is known about how religiosity shapes the human papillomavirus (HPV) vaccine decision in racial/ethnic minorities. The purpose of this study was to examine the relationship between religiosity and HPV vaccine initiation and intention among urban, racial/ethnic minority parents of adolescents 11-14 years old.

DESIGN

This study employed a descriptive, cross-sectional design using baseline data from Black and Hispanic parents (N = 175 and 285, respectively) recruited from medically underserved communities. Chi-square tests for independence and independent-samples t-tests were run to assess sociodemographic differences in vaccine initiation and vaccine intention. Binary logistic regression analyses were conducted to determine whether religious attendance and religious salience were associated with parents' HPV vaccine decisions for their children.

RESULTS

Approximately 47% of Black parents had vaccinated their youth against HPV. Of those who had not initiated the vaccine for their child, 54% did not intend to do so. 54% of Hispanic parents had initiated the HPV vaccine for their youth. Of those who had not initiated the vaccine for their child, 51% did not intend to do so. Frequency of attendance at religious services and the importance of religion in one's life was not significantly correlated with HPV vaccine decision-making for Black nor Hispanic parents.

CONCLUSION

This study suggests that religiosity does not influence the HPV vaccine decision for urban, Black and Hispanic parents. Future studies using measures that capture the complexity of religion as a social construct are needed to confirm the findings. In addition, studies with representative sampling will enable us to make generalizations about the influence of religion on HPV vaccine decision-making for urban, racial/ethnic minority parents.

Self-sampling and HPV DNA testing for cervical precancer screening in a cohort of nuns in Ghana: a cross-sectional cohort study

Background

The need for cervical cancer screening has been emphasised in at-risk cohorts of women to reduce their risk of cervical cancer. Some women with decreased risk of acquiring human papillomavirus (HPV) infections, such as Catholic nuns, receive less attention and on occasion are missed in cervical cancer screening programmes. This study aimed to determine the high-risk HPV (hr-HPV) prevalence in such a cohort to emphasise the need for cervical precancer screening among all women. To improve compliance, we employed self-sampling.

Methods

This descriptive cross-sectional cohort study involved the data of 105 Catholic nuns subjected to cervical screening using self-samples in the Greater Accra, Volta, and Central regions of Ghana between June 4, 2022 and June 30, 2022. hr-HPV testing was performed on self-samples using the MA-6000 HPV DNA platform. Screen-positive nuns underwent follow-up pap smears and EVA colposcopy. In addition to descriptive analysis, univariate and multivariable nominal logistic regression was used to explore the relationship between hr-HPV positivity and selected continuous and categorical factors.

Findings

105 nuns from three convents were screened with hr-HPV DNA testing (MA-6000). Twenty-five tested positive for hr-HPV (prevalence of 23.8% (95% CI, 15.7-32.0) [HPV 18 only (n = 2, 1.9%), non-HPV 16/18 genotypes (others) (n = 22, 21.0%), and mixed infection with HPV 16 and other genotype(s) (n = 1, 1.0%)]. Pap smears for all 25 hr-HPV-positives came in as negative for intraepithelial lesions or malignancy, whereas EVA mobile colposcopy showed minor abnormal findings in two (8.0%; 95% CI, 1.0-26.0), both of whom were managed conservatively.

Interpretation

Our findings suggest that the hr-HPV prevalence in this cohort of nuns is similar to that of the general population. To meet the World Health Organization's target for cervical cancer elimination, it is important that all women are given access to cervical cancer screening and preventative services. Further, increasing 'anonymity' and privacy among nuns through self-sampling may be crucial to expanding choice, coverage, and uptake of screening in support of their health rights.

Funding

None.

Human papillomavirus vaccinations at recommended ages: How a middle school-based educational and vaccination program increased uptake in the Rio Grande Valley

Human papillomavirus (HPV) vaccination is recommended for U.S. adolescents at ages 11-12 requiring two or three doses depending on if the vaccine series started before age 15. The objective was to compare HPV vaccination rates among medically underserved, economically disadvantaged, students in rural middle school districts (Rio Grande Valley [RGV], Texas) by age of initiation (≤ age 11 years vs. age 12 years and older). This quasi-experimental study included 1,766 students (884 females; 882 males) who received at least one HPV vaccine dose through our school-based vaccination program between 08/2016-06/2022. Summary statistics were stratified by age at initiation and gender. The overall HPV up-to-date (UTD) rate was 59.7% (95% Confidence Interval: 57.4-62.0%). The median age at HPV UTD (range) was 12 years (9-19) and median interval between HPV vaccine doses (range) was 316 days (150-2,855). Most students received the HPV vaccine bundled with other vaccinations (72.4%, 1,279/1,766). There was a higher HPV UTD rate among students who initiated the HPV vaccine on or before age 11 than those who initiated on or after age 12 (73.6% versus 45.1%, respectively). The median age of HPV UTD was age 12 for those initiating on or before 11 years versus age 13 for those initiating on or after 12 years of age. Initiating the HPV vaccine at age ≤11 years increased completion of the HPV vaccine series. Improving HPV vaccine coverage and introduction of pan-gender vaccination programs will significantly decrease HPV-related diseases in the RGV.

Factors Predicting Mothers' Intention toward Human Papilloma Virus Vaccination of Adolescents: A Cross-sectional Study Among Iranian Families

BACKGROUND

Adolescents are prone to Sexually Transmitted Diseases (STDs) such as Human Papilloma Virus (HPV). Although HPV is a preventable disease, the vaccination rate is low. As parents should vaccinate their children to prevent HPV, the goal of this study was to identify the factors related to mother's intention to vaccinate adolescents against HPV.

MATERIALS AND METHODS

This cross-sectional study was performed in Qazvin from 2019 to 2020. The participants included 126 literate mothers who had a daughter between 12 and 14 years and health system information registry. To collect the data, a questionnaire was made based on the educational model of behavioral intent. Parents were interviewed in person in health centers or via phone at home. Data were analyzed using Spearman's correlation.

RESULTS

The mean (SD) age of the mothers, fathers, and girls were 39.60 (6.18), 43.51 (7.58), 13 (0.82) years, respectively. They hadn't received education regarding HPV. The mean (SD) of the knowledge, attitude, and HPV vaccination intention scores were 27.77 (18.08), 67.38 (10.25), and 15.44 (18.44), respectively. The factors related to HPV vaccination intention were parents' knowledge (r = 0.29, p = 0.001), positive attitude (r = 0.22, p = 0.010), parents' education (r = 0.22, p = 0.050) and family income (r = 0.21, p = 0.010).

CONCLUSIONS

The high cost of vaccines, economic problems, and lack of knowledge were strong limitations for HPV vaccination. Thus, health workers should have informed parents and teens of the benefits of HPV vaccination. This process should be supported by policy makers.

Attitudinal Correlates of HPV Vaccination in College Women

This study examined associations between general attitudes toward seeking medical care, attitudes about vaccines/fear of shots, and human papillomavirus (HPV) vaccine uptake and intentions in college women. Hypothesized associations were framed by the Theory of Planned Behavior (TPB). Participants (N = 330, mean age = 18.9 years, 75% White) completed a one-time survey. The majority (61%; n = 201) had received ≥1 HPV vaccine dose. Hierarchical logistic regression examined relationships between attitudes and vaccine uptake. Pearson correlation coefficients and Kruskal-Wallis tests examined associations between attitudes and vaccine intentions. Results were partially consistent with the TPB. In the final model, perceived benefits, but not fear of shots, were associated with vaccine uptake. Among the unvaccinated, perceived benefits, but not fear of shots, were associated with vaccine intentions. Provider recommendation was the strongest predictor of vaccine uptake. Findings suggest interventions incorporating discussion of perceived benefits and provider recommendation may improve HPV vaccine receipt among college women.

State of the art vaccination strategies as primary prevention to reduce incidence of gastrointestinal cancers

Immunizations have influenced the epidemiology of numerous gastrointestinal cancers. Human papillomavirus (HPV) is a common sexually transmitted infection (STI). Although most infections are transient and asymptomatic, persistent infections with oncogenic strains of HPV can progress to cervical, anal, penile, vaginal, vulvar, and oropharyngeal cancers. The introduction of HPV vaccinations has drastically reduced incidences of HPV-vaccine related infections and HPV related cervical cancers. The vaccine has proven to be safe and effective however, HPV vaccination rates have yet to reach target goals in the U.S. and many countries worldwide have not incorporated the vaccine into national immunization programs. The first successful nationwide vaccination program was employed against hepatitis B virus (HBV) in Taiwan in 1984 and demonstrated a statistically significant decrease in the incidence of hepatocellular carcinoma (HCC) in the 6 to 10 years after implementation of universal HBV vaccinations in infants. Twenty-year follow-up studies have continued to demonstrate statistically significant decreased rates of HBV related HCC among vaccinated populations. Despite the successful decrease in incidence of HBV-related HCC, efforts to create an effective prophylactic vaccination against hepatitis C virus (HCV) to prevent chronic HCV infection and its associated morbidity, including HCV-related HCC, have to date been unsuccessful.

Faith leaders' perceptions of needle exchange programs in the rural Illinois Delta Region: Religion as a social determinant of health

BACKGROUND AND OBJECTIVES

Despite increasing drug use in rural communities, potentially life-saving harm reduction interventions, such as needle exchange programs (NEPs), remain underutilized. Religion is an integral component of the rural culture that has been shown to influence health, yet no studies to date have explored rural faith leaders' perceptions of harm reduction strategies.

METHODS

An online cross-sectional survey was conducted among rural faith leaders (n = 133) in the rural Illinois Delta Region.

RESULTS

While most of the respondents felt that drug abuse was an issue in their communities, support was mixed regarding whether they were in favor of NEPs with the majority of respondents having never heard of an NEP before this survey. While the majority believed that NEPs would help decrease bloodborne disease transmission, it was also perceived that NEPs would increase drug use. Significant differences in perceptions based on race, marital status, and political party also exist.

CONCLUSION AND SCIENTIFIC SIGNIFICANCE

Congruent with previous harm reduction literature, many rural faith leaders have varied perceptions of NEPs. Rural faith leaders could benefit from education about NEPs, including the possible positive and negative impacts they can have on the community. Future studies should explore contextual differences among rural faith leaders. To date, no studies have examined faith-based organizations' perceptions of NEPs. The findings have the potential to increase the current body of knowledge and provide data to support recommendations for engaging faith-based organizations in behavioral health service delivery.

Changes in Strength of Recommendation and Perceived Barriers to Human Papillomavirus Vaccination: Longitudinal Analysis of Primary Care Physicians, 2008-2018

OBJECTIVES

To evaluate among pediatricians and family physicians human papillomavirus (HPV) vaccination recommendation practices for 11- to 12-year-old youth; report parental refusal/deferral of HPV vaccination; and report barriers to HPV vaccination changed over time.

STUDY DESIGN

We surveyed nationally representative networks of pediatricians and family physicians in 2008, 2010, 2013-2014, and 2018. Male vaccination questions were not asked in 2008; barriers and parental vaccine refusal questions were not asked in 2010.

RESULTS

Response rates were 80% in 2008 (680/848), 72% in 2010 (609/842), 70% in 2013-2014 (582/829), and 65% in 2018 (588/908). The proportion of physicians strongly recommending HPV vaccination for 11- to 12-year-old patients increased from 53% in 2008 to 79% in 2018 for female patients and from 48% in 2014 to 76% in 2018 for male patients (both P < .0001). The proportion of physicians indicating ≥50% of parents refused/deferred HPV vaccination remained steady for female patients (24% in 2008 vs 22% in 2018, P = .40) and decreased for male patients (42% in 2014 vs 28% in 2018, P < .001). Physician barriers to providing HPV vaccination were rare and decreased over time. Increasing numbers of physicians reported perceived parental barriers of vaccine safety concerns (5% "major barrier" in 2008 vs 35% in 2018, P < .0001) and moral/religious concerns (5% in 2008 vs 25% in 2018, P < .0001).

CONCLUSIONS

Between 2008 and 2018, more primary care physicians reported recommending HPV vaccination for adolescents, fewer reported barriers, and more physicians reported parents who had vaccine safety or moral/religious concerns.

A systematic review of human papillomavirus vaccination among US adolescents

The human papillomavirus (HPV) causes many anogenital and oral cancers affecting young adults in the United States. Vaccination during adolescence can prevent HPV-associated cancers, but vaccine uptake among adolescents is low and influenced by factors serving as barriers and facilitators to HPV vaccination. In this systematic review, we synthesized research using the socioecological framework model to examine individual-level, relationship-level, community-level, and societal-level factors that influence HPV vaccine initiation and completion among US adolescents. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to guide the methodology for this review. An electronic search was conducted in January 2020 using PubMed, Cumulative Index of Nursing and Allied Health Literature, ProQuest Central, Scopus, and American Psychological Association PsycInfo databases. The Joanna Briggs Institute tools were used to assess the quality for the 57 studies included in this review. The most consistent influences of HPV vaccination included age at vaccination, awareness, and knowledge about HPV vaccination, socioeconomic status, insurance status, race/ethnicity, and preventative care behaviors at the individual level. Provider recommendation, familial/peer support of vaccination, and parental health behaviors were influences at the relationship level. Although fewer findings elucidated community-level and societal-level influences, high-poverty areas, high-risk communities with large proportions of racial/ethnic minority groups, healthcare facilities servicing children, and combined health policies appear to serve as facilitators of HPV initiation and completion. Findings from this review can inform culturally relevant and age-specific interventions and multi-level policies aiming to improve HPV vaccination coverage in the United States.

Practice-, provider- and patient-level facilitators of and barriers to HPV vaccine promotion and uptake in Georgia: a qualitative study of healthcare providers' perspectives

Georgia experiences higher human papillomavirus (HPV)-associated cancer burden and lower HPV vaccine uptake compared with national estimates. Using the P3 model that concomitantly assesses practice-, provider- and patient-level factors influencing health behaviors, we examined facilitators of and barriers to HPV vaccine promotion and uptake in Georgia. In 2018, we conducted six focus groups with 55 providers. Questions focused on multilevel facilitators of and barriers to HPV vaccine promotion and uptake. Our analysis was guided by the P3 model and a deductive coding approach. We found that practice-level influences included organizational priorities of vaccinations, appointment scheduling, immunization registries/records, vaccine availability and coordination with community resources. Provider-level influences included time constraints, role, vaccine knowledge, self-efficacy to discuss HPV vaccine and vaccine confidence. Patient-level influences included trust, experiences with vaccine-preventable diseases, perceived high costs, perceived side effects and concerns with sexual activity. Findings suggest that interventions include incentives to boost vaccine rates and incorporate appointment scheduling technology. An emphasis should be placed on the use of immunization registries, improving across-practice information exchange, and providing education for providers on HPV vaccine. Patient-provider communication and trust emerge as intervention targets. Providers should be trained in addressing patient concerns related to costs, side effects and sexual activity.

Conceiving an application ontology to model patient human papillomavirus vaccine counseling for dialogue management

Background

In the United States and parts of the world, the human papillomavirus vaccine uptake is below the prescribed coverage rate for the population. Some research have noted that dialogue that communicates the risks and benefits, as well as patient concerns, can improve the uptake levels. In this paper, we introduce an application ontology for health information dialogue called Patient Health Information Dialogue Ontology for patient-level human papillomavirus vaccine counseling and potentially for any health-related counseling.

Results

The ontology’s class level hierarchy is segmented into 4 basic levels - Discussion, Goal, Utterance, and Speech Task. The ontology also defines core low-level utterance interaction for communicating human papillomavirus health information. We discuss the design of the ontology and the execution of the utterance interaction.

Conclusion

With an ontology that represents patient-centric dialogue to communicate health information, we have an application-driven model that formalizes the structure for the communication of health information, and a reusable scaffold that can be integrated for software agents. Our next step will to be develop the software engine that will utilize the ontology and automate the dialogue interaction of a software agent.

Parental knowledge gaps and barriers for children receiving human papillomavirus vaccine in the Rio Grande Valley of Texas

Purpose: Despite its availability for more than a decade, the human papillomavirus (HPV) vaccine has low uptake in Texas (49%). The objective of this study was to understand parental knowledge and attitudes about HPV and the HPV vaccine as well as child experience with the HPV vaccine among a medically underserved, economically disadvantaged population.

Methods: As part of a Cancer Prevention Research Institute of Texas-funded project to improve HPV vaccination rates, we surveyed parents / guardians of 4^th–12^th graders (ages 9–17) in the Rio Grande City Consolidated Independent School District (RGCCISD). Descriptive statistics were used to describe parents’ knowledge and attitude and children’s vaccine experience.

Results: Of the 7,055 surveys distributed, 622 (8.8%) were returned. About 84% of the respondents were female. About 57.1% of the parents /guardians had female RGCCISD students with a mean age of 11.7 ± 1.8 years. Overall, 43.9% reported receiving a healthcare provider recommendation and 32.5% had their child vaccinated. Higher percentages were reported if the respondent was female and had a female child aged ≥15 years old. Among survey respondents, 28.2% reported their child initiated the HPV vaccine and 18.8% completed the series. Barriers of uptake included work / school schedule conflicts and no healthcare provider recommendation.

Conclusions: There are still prominent gaps in parents’ and students’ complete understanding of HPV vaccination, gender preferences for vaccination, and provider recommendations. Future interventions must target men and minority populations in order to increase knowledge and awareness about HPV, the HPV vaccine, and HPV-associated cancers.

HPV Vaccine-Related Research, Promotion and Coordination in the State of Georgia: A Systematic Review

Human papillomavirus (HPV) vaccine was first recommended for female adolescents in the United States in 2006, and for male adolescents in 2011. In 2016, national HPV vaccine coverage was 43.4%, and slightly higher in Georgia (45.6%). Little is known about sub-state-level variation in HPV vaccination or Georgia specific research conducted to improve HPV vaccine uptake. We aimed to describe current uptake of HPV vaccination and synthesize Georgia-specific research of HPV vaccine uptake. We reviewed existing published and grey literature for different development, implementation and best practices related to vaccine uptake in adolescents. Studies measuring HPV vaccine uptake in Georgia utilizing quantitative, qualitative, or mixed-methods approaches were included alongside state-level information from National Immunization Survey-Teen, Community Health Needs Assessments, Behavioral Risk Factor Surveillance and Georgia Adolescent Immunization Surveys. Key findings across these reports were summarized. Forty-two titles and abstracts were identified through electronic database search for literature published between 2006 and 2017. Of these, five were from database sources and 37 were from additional sources. The most often mentioned barriers of HPV vaccine uptake in Georgia include cultural norms, vaccination education and a misalignment of vaccine uptake goals between the state and regional hospital community needs assessments. Increasing knowledge and uptake of HPV vaccine in Georgia requires significant research and to understand the vast socioeconomic, cultural and geographic barriers preventing uptake among adolescents. Georgia-specific efforts have been limited, however ongoing collaborations spearheaded by the Georgia Cancer Control Coalition provide opportunities for state-level support of research to address these barriers.

Human Papillomavirus Vaccine Interventions in the U.S.: A Systematic Review and Meta-analysis

CONTEXT

Despite current recommendations, human papillomavirus vaccine uptake remains low. A systematic review and meta-analysis assessed the effectiveness of interventions targeting human papillomavirus vaccine initiation and completion among children, adolescents, and young adults aged 9-26 years.

EVIDENCE ACQUISITION

Three electronic databases (CINAHL, OVID, and Web of Science) were searched for articles published in English peer-reviewed journals between January 2006 and January 2017 of U.S. studies that evaluated intervention strategies and reported post-intervention human papillomavirus vaccine initiation or completion rates among individuals aged 9-26 years. Study characteristics and outcomes were extracted. Data were collected in 2016 and analyzed in 2017.

EVIDENCE SYNTHESIS

Reviewers screened 983 unique titles and abstracts, read 241 full-text articles, and extracted data from 30 articles meeting the inclusion criteria (12 behavioral, ten environmental, four informational, and four combination strategies). Published EQUATOR (Enhancing the Quality and Transparency of Health Research) guidelines were used to assess study quality. Random effects meta-analyses were conducted. The meta-analyses included 17 RCTs and quasi-experiments involving 68,623 children, adolescents, and young adults. The pooled relative incidence estimates were 1.84 (95% CI=1.36, 2.48) for human papillomavirus vaccine initiation and 1.50 (95% CI=1.23, 1.83) for completion. Behavioral and informational interventions doubled human papillomavirus vaccine initiation (relative incidence estimate=2.04, 95% CI=1.36, 3.06 and relative incidence estimate=1.92, 95% CI=1.27, 2.91, respectively). Behavioral interventions increased completion by 68% (relative incidence estimate=1.68, 95% CI=1.25, 2.27).

CONCLUSIONS

Evidence supports behavioral interventions for increasing human papillomavirus vaccine initiation and completion. Future studies are needed to assess the effectiveness of interventions in reaching diverse populations and reducing missed opportunities for human papillomavirus vaccination.

HPV vaccine acceptance among African-American mothers and their daughters: an inquiry grounded in culture

BACKGROUND

Much of the research on African-Americans' HPV vaccine acceptance has largely focused on racial/ethnic differences related to cognitive, socio-economical, and structural factors that contribute to differences in HPV vaccine acceptance and completion. A growing body of literature suggest that cultural factors, such as mistrust of healthcare providers (HCPs) and the healthcare system, religion, and social norms related to appropriate sexual behaviors, also plays a prominent role in their HPV vaccine acceptance. However, these studies were limited in their use of theoretical approaches necessary to conceptualize and operationalize culture.

OBJECTIVE

To explore the influence of culture on African-American mothers' and daughters' HPV vaccine acceptance using the PEN-3, a culturally-centered conceptual framework.

METHODS

Grounded theory techniques were used to explore cultural factors that influenced the acceptance of the HPV vaccine among African-American mothers (n = 28) and their daughters (n = 34).

RESULTS

Positive attitudes towards vaccination stemmed from beliefs that the HPV vaccine has cancer prevention benefits and that vaccinations in general protected against infectious diseases. Negative attitudes stemmed from beliefs that the HPV vaccine was too new, not effective, daughters were too young, and that vaccines were not a one-size-fits-all intervention. Majority of mothers and daughters indicated that their religious doctrine did not impede their HPV vaccination decisions. For a few mothers, religious beliefs could not be separated from their HPV vaccination decisions and ultimately deterred HPV vaccine acceptance. HCP recommendations were valued however mothers were often dissatisfied with the detail of information communicated. Support networks provided both positive and negative types of social support to mothers and daughters. The media highlighted the cancer prevention benefits of the HPV vaccine and unintentionally communicated negative information of the HPV vaccine, which deterred HPV vaccine acceptance.

CONCLUSION

Study findings can inform the development of culturally appropriate interventions that advances the evidence on cervical cancer prevention.

Associations between population based voting trends during the 2016 US presidential election and adolescent vaccination rates

BACKGROUND

Politics play a role in the dissemination of public health information, including immunization-related issues. We aim to describe relationships between HPV vaccination rates and state voting patterns during the 2016 US presidential election.

METHODS

We classified each of the 50 states as either "Red" or "Blue," based on whether a higher proportion of the state's casted votes were for the Republican or Democratic nominee during the 2016 US presidential election. State-specific HPV, Tdap, and meningococcal vaccination rates were obtained from the 2016-National Immunization Survey-Teen. State socio-demographic factors and HPV vaccine legislation were obtained from the US Census Bureau and National Conference of State Legislatures. Vaccination rates and socio-demographic variables were compared using independent t-tests. Multiple linear regression compared vaccination rates between "Red" and "Blue" states, adjusting for percentage of both uninsured children and educational attainment.

RESULTS

Compared to "Blue" states, "Red" states had significantly lower unadjusted HPV vaccine series initiation (56% vs 66%, p < 0.05) and completion (39% vs 50%, p < 0.05) rates; yet had similar rates of Tdap (88% vs 89%, p > 0.05) and meningococcal (79% vs 83%, p > 0.05) vaccinations. After adjusting for potential confounders, the regression-adjusted mean rate for HPV vaccine initiation and completion remained significantly lower for "Red" states compared to "Blue" states (57% vs 65%, p < 0.05, and 41% vs 48%, p < 0.05, respectively).

CONCLUSION

HPV vaccination rates are associated with statewide-level voting patterns. Future interventions aimed at improving HPV vaccination rates should consider engaging local and national elected leaders to be proactive in disseminating accurate and authoritative immunization information.

Correlates of HPV vaccine initiation and provider recommendation among male adolescents, 2014 NIS-Teen

Vaccination is a safe and effective way to prevent Human Papillomavirus (HPV) infection and related cancers; however, HPV vaccine uptake remains low in the US. After the 2011 Advisory Committee on Immunization Practices (ACIP) recommendation for routine HPV vaccination of adolescent males, several studies have examined predictors for initiating the vaccine series in this population of interest, particularly with regard to provider recommendations. This study examined racial and ethnic differences for HPV vaccine initiation and provider recommendation in male adolescents. Based on prior HPV vaccine uptake estimates and healthcare utilization data, we hypothesized that minority adolescents would be more likely to initiate HPV vaccines, but less likely to receive a provider recommendation compared to white counterparts. We analyzed the 2014 National Immunization Survey-Teen (NIS-Teen), which included 10,753 male adolescents with provider-verified vaccination data in 50 US states, using multivariate logistic regression models to evaluate racial/ethnic differences in HPV vaccine initiation and provider recommendation. The odds of HPV vaccine initiation were 76 percent higher for Hispanic adolescents and 43 percent higher for non-Hispanic Other or Multiple race adolescents compared to white adolescents. Approximately half of parents reported receiving a provider recommendation for vaccination, with no significant difference in the odds of receiving a provider recommendation across racial/ethnic groups. Despite similar frequency of recommendations across racial and ethnic groups, male adolescents who are racial/ethnic minorities are more likely to initiate vaccination. Future research should focus on developing tailored interventions to increase HPV vaccine receipt among males of all racial/ethnic groups.

Barriers and facilitators to HPV vaccination among rural Alabama adolescents and their caregivers

INTRODUCTION

Half of all new human papillomavirus (HPV) infections occur in adolescents and young adults, and this population has poor HPV vaccination rates. Rural areas of the U.S. have high rates of HPV-related diseases and low vaccination rates as well. The purpose of this study was to determine the perceived barriers and facilitators to HPV vaccination among adolescents and their caregivers in rural south Alabama.

METHODS

Vaccinated and non-vaccinated adolescents ages 11-18 years old and primary caregivers were recruited from three rural counties in south Alabama. Participants completed individual interviews to discuss perceived barriers to vaccination and factors influencing their decision to vaccinate. Discussion groups were held to determine potential solutions to barriers elucidated from the interviews. Interview and discussion group transcripts were analyzed, and themes were identified.

RESULTS

Approximately 62.5% of adolescents had not initiated the HPV vaccine series. Of those adolescents who started the vaccine series (n = 9, 37.5%), about half completed it (n = 5). Few participants in this study reported speaking with their health care provider (HCP) about the vaccine in the past year. Lack of information about the vaccine, its side effects, and no HCP recommendation were common barriers cited by non-vaccinators. Facilitators to vaccination included cancer prevention, discussion with HCP, and peer testimonials. Potential solutions to barriers were also discussed.

CONCLUSIONS

Proposed strategies to increase HPV vaccination were similar between vaccinated and non-vaccinated groups. Education about HPV and the HPV vaccine is needed throughout these rural south Alabama communities to ensure informed decisions are made about vaccination and to increase vaccination rates.

Parents' knowledge, beliefs, and acceptance of the HPV vaccination in relation to their socio-demographics and religious beliefs: A cross-sectional study in Thailand

Thailand has one of the world's highest prevalence of cervical cancer, mainly caused by the human papillomavirus (HPV). HPV infections can successfully be prevented by vaccination, which is available at a cost but not yet implemented in the national vaccination program. Parents play a critical role in deciding whether to vaccinate their child against HPV. Thus, the aim was to examine the association between parents' knowledge, beliefs, and acceptance of the HPV vaccination for their daughters, considering their socio-demographics and religious beliefs. A cross-sectional design was used among three schools in Thailand: Nakorn Phatom province (suburban) and Bangkok (urban). Parents of 9-12-year-old daughters completed the questionnaires, guided by the Health Belief Model. In total, 359 parents completed the questionnaires; of those, 301 were included in the final analyses. The ordinary least squares (OLS) regression analysis showed that background knowledge of HPV and the HPV vaccine was positively related to knowledge of HPV and cervical cancer. For beliefs, knowledge was positively associated with susceptibility (i.e., parents' perceived risk of an HPV infection/ related disease), severity, and benefit. However, knowledge was not significantly related to barriers. For acceptance, higher susceptibility and benefit were related to higher acceptance, and greater knowledge was associated with higher acceptance. Thus, we found associations between parents' knowledge, beliefs, and acceptance of the HPV vaccination for their daughters, considering their socio-demographics and religious beliefs. Parents, who reported religion as important, as opposed to those who did not, were more favorable toward the HPV vaccination. Four out of ten mothers had never undergone a cervical cancer screening, but most had accepted previous childhood vaccinations for their daughters. The overall acceptance of the vaccine was high, and we believe our results are promising for future implementation of the HPV vaccination in the national childhood vaccination program in Thailand.

Multimodal Counseling Interventions: Effect on Human Papilloma Virus Vaccination Acceptance

Human papilloma virus (HPV) vaccine was developed to reduce HPV-attributable cancers, external genital warts (EGW), and recurrent respiratory papillomatosis. Adolescent HPV vaccination series completion rates are less than 40% in the United States of America, but up to 80% in Australia and the United Kingdom. Population-based herd immunity requires 80% or greater vaccination series completion rates. Pro-vaccination counseling facilitates increased vaccination rates. Multimodal counseling interventions may increase HPV vaccination series non-completers’ HPV-attributable disease knowledge and HPV-attributable disease prophylaxis (vaccination) acceptance over a brief 14-sentence counseling intervention. An online, 4-group, randomized controlled trial, with 260 or more participants per group, found that parents were more likely to accept HPV vaccination offers for their children than were childless young adults for themselves (68.2% and 52.9%). A combined audiovisual and patient health education handout (PHEH) intervention raised knowledge of HPV vaccination purpose, p = 0.02, and HPV vaccination acceptance for seven items, p < 0.001 to p = 0.023. The audiovisual intervention increased HPV vaccination acceptance for five items, p < 0.001 to p = 0.006. That HPV causes EGW, and that HPV vaccination prevents HPV-attributable diseases were better conveyed by the combined audiovisual and PHEH than the control 14-sentence counseling intervention alone.

Religion and HPV vaccine-related awareness, knowledge, and receipt among insured women aged 18-26 in Utah

INTRODUCTION

We investigate the associations between religious practice and human papillomavirus (HPV) vaccine-related awareness, knowledge, and receipt among young women in Utah.

METHODS

We surveyed 326 insured women aged 18-26 by mail. Fisher's Exact Tests and multivariable logistic regression models were used to evaluate the relations between religious practice and HPV vaccine-related outcomes. Data collection occurred January-December 2013; analyses were conducted June-September 2015.

RESULTS

Multivariable analyses reveal that when controlling for age, educational attainment, and marital status, participants who practiced an organized religion were significantly less likely to have heard of HPV (aOR = 0.25, p = 0.0123), to have heard of the HPV vaccine (aOR = 0.41, p = 0.0368), to know how HPV is spread (aOR = 0.45, p = 0.0074), to have received a provider recommendation for the HPV vaccine (aOR = 0.36, p = 0.0332), and to have received at least one (aOR = 0.50, p = 0.0073) or all three (aOR = 0.47, p = 0.0026) doses of the HPV vaccine. Bivariate analyses produce parallel results.

CONCLUSIONS

Results indicate that religious young women in Utah are not only under-vaccinated, but are also under-informed about HPV and the HPV vaccine. These results suggest that suboptimal vaccine coverage among religious young women may present a serious health risk for the community. Strategies for educational interventions targeted to this population are discussed.

Mothers, Fathers, Sons, and Human Papillomavirus Immunization Practices

Despite the fact that human papillomavirus (HPV) infection and HPV-related cancers are on the rise in men, male HPV vaccine series completion is less than 10% in many areas. This study examined parental knowledge of the HPV vaccine and intent to vaccinate their sons. A cross-sectional study of 341 parents of boys was conducted in school settings in rural southeastern Georgia. Mothers were 2.07 times more likely than fathers to vaccinate their sons. Future research directions should include strategies to increase HPV vaccination in both genders and focus on parents' perceived severity and vulnerability of their sons to HPV infection.

What explains the different rates of human papillomavirus vaccination among adolescent males and females in the United States?

PURPOSE

To identify factors that explain differences in HPV vaccination rates for male and female adolescents and to determine self-reported barriers by parents affecting vaccination decisions.

METHODS

The sample included adolescents 13-17 years old with a vaccination record documented in the 2012 and 2013 National Immunization Survey-Teen dataset. A logistic regression model was developed with 13 socio-demographic factors and survey year, along with significant interaction pairs with gender.

RESULTS

Subjects included 20,355 and 18,350 adolescent boys and girls, respectively. About half of the females (56%) received at least one dose of HPV vaccine, compared to 28% of males. Several factors differed between males and females, including higher vaccination rates among non-Hispanic Black males and lower vaccination rates for non-Hispanic Black females compared to Whites; and a stronger association with health care provider recommendation among males. The most common parental reasons for not vaccinating their children included 'not recommended by a health care provider' for males (24%), and 'unnecessary' for females (18%).

CONCLUSION

We found a significant gender interaction with several socio-demographic variables in predicting vaccination uptake. These gender differences may be partially an artifact of timing, because male vaccination became routine approximately five years after female vaccination.

Cancer Prevention: HPV Vaccination

OBJECTIVES

To provide an overview of human papillomavirus (HPV) vaccination as cancer prevention with current strategies that nurses can use to help patients and parents overcome barriers to HPV vaccination.

DATA SOURCES

Peer-reviewed literature, presentation abstracts, and current immunization recommendations from the Advisory Council on Immunization Practice.

CONCLUSION

Nurses can help prevent cancer by encouraging HPV vaccination during routine immunization and make HPV vaccination normal and routine.

IMPLICATIONS FOR NURSING PRACTICE

A vaccine to reduce/eliminate HPV-related cancers enables nurses' at all educational levels to advocate for cancer prevention through initiation and completion of the HPV vaccine series.

Human Papillomavirus Infection and Vaccination

Human papillomavirus (HPV) is an infection that can be sexually transmitted and result in health consequences including genital warts and cancers. Two vaccines, Gardasil® [Human Papillomavirus Quadrivalent (Types 6, 11, 16, and 18) Vaccine, Recombinant] and Cervarix™ [Human Papillomavirus Bivalent (Types 16 and 18) Vaccine], have been approved for the prevention of HPV and HPV-related diseases.

OBJECTIVES

To explore facilitators and barriers associated with HPV vaccine utilization and compliance regarding vaccine series completion in school-aged, adolescent, and young adult females in the United States; to discuss HPV infection and highlight the safety and efficacy of the HPV vaccine; and to illustrate delivery strategies that can improve immunization rates and review implications for healthcare providers.

METHODS

A literature review was performed using health-related online databases (CINAHL, MEDLINE, PubMED, Web of Science, EBSCOHost and Google Scholar) and archival searching to identify current vaccination rates and factors associated with vaccine uptake.

RESULTS

Despite the availability of vaccines that prevent cancer, acceptance and utilization rates of both HPV vaccines are less than recommended by the Advisory Committee for Immunization Practices (ACIP). Some of the barriers to HPV vaccination include lack of provider recommendation, negative parent or patient attitudes and beliefs, cost, and missed clinical opportunities. The primary facilitator to HPV vaccination is a strong provider recommendation.

CONCLUSIONS

Healthcare providers can enhance HPV vaccine utilization by taking an active role with patients. Strategies include education and advocacy for receiving the vaccine, maximizing access to the HPV vaccine, and implementing new strategies for vaccine-delivery.

Student HPV vaccine attitudes and vaccine completion by education level

PURPOSE

We describe HPV vaccine attitudes among students of different education levels.

METHODS

High school, college, and graduate-level health care professional students were surveyed regarding HPV vaccine knowledge, attitudes, and receipt. Relationships between categorical variables were analyzed using chi-square tests of independence and z-tests for proportions. Means for quantitative variables were compared using t-tests and one-way analysis of variance.

RESULTS

57% and 42% of the 889 students reported starting and completing HPV vaccine series, respectively, with no statistical difference by education level. 61% of students who reported receiving a provider recommendation had completed the series, compared to 6% of those who did not receive recommendation (p<0.001). The belief that HPV vaccine prevents cancer was strongly associated with vaccine completion (p=0.003).

CONCLUSION

HPV vaccine coverage rates remain suboptimal. Future interventions should focus on improving provider recommendation and patient belief that HPV vaccine prevents cancer.

The Influence of Religiosity and Spirituality on Rural Parents' Health Decision Making and Human Papillomavirus Vaccine Choices

General health implications of religiosity and spirituality on health have been associated with health promotion, so the purpose of this study was to examine the influence of religiosity and spirituality on rural parents' decision making to vaccinate their children against human papillomavirus (HPV). The associations of religiosity and spirituality with parental HPV vaccine decisions were examined in a sample of parents residing in small rural communities (N = 37). Parents of children aged 9 to 13 years participated in focus groups held in rural community contexts. Religiosity (i.e., participation in religious social structures) was a recurring and important theme when discussing HPV vaccination. Spirituality (i.e., subjective commitment to spiritual or religious beliefs) was found to influence the ways in which parents perceived their control over and coping with health issues potentially related to HPV vaccination. Together, religiosity and spirituality were found to play integral roles in these parents' lives and influenced their attitudes toward HPV vaccination uptake for their children.

Overcoming the triad of rural health disparities: How local culture, lack of economic opportunity, and geographic location instigate health disparities

OBJECTIVE

To discuss how the effects of culture, economy, and geographical location intersect to form a gestalt triad determining health-related disparities in rural areas.

METHODS

We critically profile each component of the deterministic triad in shaping current health-related disparities in rural areas; evaluate the uniquely composed intersections of these disparities in relation to Human Papillomavirus (HPV)-related cancer prevention in three isolated rural Georgia counties; and develop implications for future leadership in rural healthcare research, policy, and practice.

RESULTS

The deterministic triad of culture, economy, and geographical location is unique to a rural community, and even if two rural communities experience the same health disparity, each community is likely to have a discretely different composition of cultural, economic, and geographic determinants.

CONCLUSION

The deterministic triad presents a challenge for health policymakers, researchers, and practitioners trying to develop health-related interventions that are equitable, efficacious, and practical in low-resource rural communities. The situation is worsened by the limited opportunities for employment, which leads to greater disparities and creates propagating cultural norms that further reduce access to healthcare and opportunities for sustainable health promotion.

Adolescent risk-taking, cancer risk, and life course approaches to prevention

Adolescent risk-taking may have long-term consequences for adult cancer risk. Behaviors such as smoking and sexual activity, commonly initiated during adolescence, may result--decades later--in cancer. Life course epidemiology focuses on unique vulnerabilities at specific development periods and their importance to later development of disease. A life course epidemiological perspective that integrates social and biological risk processes can help frame our understanding how specific adult cancers develop. Moreover, life course perspectives augment traditional public health approaches to prevention by emphasizing the importance of unique windows of opportunity for prevention.

Highlights from a workshop on opportunities for cancer prevention during preadolescence and adolescence

In an effort to explore opportunities for cancer prevention during preadolescence and adolescence, the Cancer Prevention Across the Lifespan workgroup within the Division of Cancer Prevention and Control at the Centers for Disease Control and Prevention (CDC) convened an informal panel of experts for a 2-day workshop August 9-10, 2011. In this report, we provide highlights from the workshop. A central theme of the workshop was that preadolescence and adolescence are times of unique susceptibility and vulnerability within the lifespan. Participants discussed the evidence linking exposures during adolescence (e.g., risky behaviors, chemicals, medical imaging procedures) and subsequent cancer risk during adulthood. Participants also discussed potential opportunities to intervene on risk factors for cancer at multiple levels during adolescence, the importance of more focused approaches to adequately address health disparities, and the ongoing need for transdisciplinary and translational prevention research. Future opportunities for the CDC include further leveraging surveillance data from sources such as the National Health and Nutrition Examination Survey, the Youth Risk Behavior Surveillance System, and the National Children's Study and continuing to build on collaborations with other federal agencies and with national, state, and local organizations. Many ideas and insights generated during the workshop will be put into action as CDC continues to explore opportunities for cancer prevention during youth and across the lifespan.

Cancer prevention for the next generation

Given the continued growth in the number of persons with cancer in the United States, the primary prevention of cancer remains an urgent public health priority. As the field of cancer prevention continues to mature and scientific knowledge evolves, it is imperative to challenge the status quo and embrace new approaches to cancer prevention. In this commentary, we summarize recent trends and some of the scientific advances that have been made over the past few decades regarding the complex process of cancer development and the interaction of individual and social risk factors. We examine some of the assumptions and terminology that have characterized cancer prevention approaches for more than a quarter century and the impact of these assumptions and our use of terminology. We propose that it is possible for today's youth to experience lower cancer incidence rates as adults compared with previous generations. To accomplish this goal, a more transdisciplinary and multifaceted approach is needed, adapted as appropriate for different populations and stages of life. The greatest improvements in cancer prevention may occur as a result of innovative, multilevel interventions that build on the expanding scientific evidence base.

Turning disciplinary knowledge into solutions

Turning disciplinary knowledge about preadolescents' and adolescents' exposure to risk factors for cancer as adults into solutions for preventing such an outcome requires that investigators from a variety of backgrounds and disciplines come together to share knowledge. Optimally, these collaborations would occur across two dimensions: (1) transdisciplinary, from the molecular or cellular level (e.g., animal studies of endocrine disruption) to the societal level (e.g., economic studies related to state tobacco policies); and (2) translational, using basic research findings in clinical and other sciences to implement prevention programs and public policy. Only when collaboration is commonplace can the disparate groups of investigators working on cancer prevention during preadolescence and adolescence gain a holistic picture of the risk factors, inform one another's work, and learn what we need to know to devise successful interventions for preventing cancer. Working transdisciplinarily also helps to ensure that messages to health professionals, policymakers, the news media, and the public are consistent and coordinated. At present, those investigating preadolescent and adolescent risk for adult cancer disseminate their knowledge individually, thus missing the opportunity to synthesize knowledge, coordinate dissemination, and implement prevention programs. In this article, we distinguish multidisciplinary, interdisciplinary, and transdisciplinary approaches; argue for the benefits of a transdisciplinary approach to devising successful solutions; and explore how to achieve transdisciplinary functioning.

Rural African American parents' knowledge and decisions about human papillomavirus vaccination

PURPOSE

To identify predictors of human papillomavirus (HPV) vaccination among rural African American families.

DESIGN

Cross-sectional descriptive study in schools in three rural counties in southeastern United States. The sample consisted of African American parents or caregivers with children 9 to 13 years of age who attended elementary or middle school in 2010-2011.

METHODS

Using an anonymous, 26-item survey, we collected descriptive data during parent-teacher events from African American parents with children in elementary or middle school. The main outcome was measured as a response of "yes" to the statement "I have or will vaccinate my child with the HPV vaccine." In addition, composite scores of knowledge and positive attitudes and beliefs were compared. No interventions were conducted.

FINDINGS

We identified predictors of HPV vaccination and found that religious affiliation had a correlation with vaccinating or planning to vaccinate a child.

CONCLUSIONS

Results indicate a need for further research on the role of local culture, including religion and faith, in rural African Americans' decisions about giving their children the HPV vaccination.

CLINICAL RELEVANCE

This study emphasizes the importance of understanding rural African American parents' knowledge, attitudes, and spiritual beliefs when designing health education programs and public health interventions to increase HPV vaccination uptake among African American boys and girls living in rural areas.
