Men's knowledge of the human papillomavirus vaccine

A systematic review and thematic synthesis exploring how gay, bisexual and other men who have sex with men (GBMSM) experience HPV and HPV vaccination

There are suboptimal levels of HPV vaccine uptake among gay, bisexual and men who have sex with men (GBMSM), despite the prevalence and incidence rates of HPV infection among GBMSM being higher than heterosexual males. This systematic review provides a thematic synthesis of qualitative research which examined the perceptions and experiences of GBMSM to HPV vaccine acceptability and explored the barriers and facilitators to participating in HPV vaccination. This review offers new insights about GBMSM understandings of HPV and how they are shaped by a complex relationship between limited knowledge and information of HPV, feminization of HPV with the focus on cervical cancer and women, and the socio-political governmentality of health services in meeting their health needs. Public health communication is required that focuses on the risks of HPV for anal, penile and oropharyngeal cancers and is culturally congruent to tailor and work with GBMSM more effectively for HPV vaccination. Healthcare providers need training around sexual health stigma and should proactively offer the HPV vaccination outside sexual health clinics for this vulnerable group.

Acceptance of Human Papillomavirus (HPV) vaccine among the parents of eligible daughters (9-15 years) in Bangladesh: A nationwide study using Health Belief Model

BACKGROUND

To align with the 2030 vision of the World Health Organization (WHO) to ensure 90% of girls receive the HPV vaccine before turning 15, Bangladesh has recently started the (HPV) vaccine campaign nationwide. Therefore, our study aimed to assess the level of its acceptance among parents of eligible daughters in Bangladesh.

METHODS

This nationwide cross-sectional study was conducted among the self-identified parents of daughters in the age group of 9-15 years between June 28 and August 2, 2023. A total of 2,151 parents were conveniently selected from all eight divisions of Bangladesh. Data was collected through face-to-face interviews using a semi-structured questionnaire. The Health Belief Model was used to appraise respondents' beliefs concerning HPV and its vaccination. Adjusted odds ratios (AOR) with a corresponding 95% confidence interval (CI), and a p-value of <0.05 was considered statistically significant. R Studio (Version 2023.09.0+463) was used as an interface for data analysis, while R (the programming language) was used for statistical computations.

RESULTS

The mean age of the study participants was 38.18 (±5.86) years. The overall acceptance rate of the HPV vaccine was 86.61% (95%CI: 85.09-88.02). The vaccine acceptance level was positively associated with all the domains of the HBM (p<0.001), except in the perceived barrier domain (p = 0.489). After adjustment for other factors, it was found that higher age was associated with a decreased acceptance (AOR: 0.92; 95% CI: 0.89-0.95). The urban residents exhibited 42% lower odds of vaccine acceptance than rural (AOR: 0.58; 95% CI: 0.36-0.92). Similarly, participants of the middle-income group had 44% lower odds than the lower-income group (AOR: 0.56; 95% CI: 0.32-0.97).

CONCLUSION

Our study found a reasonably good level of acceptance of the HPV vaccine among the parents of eligible daughters. Multiple factors such as younger age, urban residence, belonging to the middle income group, history of regular routine health check-ups, knowledge of cervical cancer, positive perception about benefits of the vaccine, and positive cues to actions were associated with HPV vaccine acceptance.

Human Papillomavirus associated prevention: knowledge, attitudes, and perceived risks among men who have sex with men and transgender women in Pakistan: a qualitative study

OBJECTIVES

Men who have sex with men (MSM) and transgender individuals are at higher risk of genital warts and anal cancer due to sexually transmitted human papillomavirus infection. This study explores MSM and transgender women's perceptions of Human papillomavirus (HPV) infection and HPV prevention strategies (screening and vaccination) in Pakistan.

DESIGN

A qualitative study using focus group discussions (FGD) with self-identified MSM, male sex workers and transgender women were conducted between March 2019 to August 2019 in Karachi, Pakistan.

METHODS

Participants were recruited from community-based organization (CBO) working for MSM and transgender women. A total of 38 men and 10 transgender women took part in 6 FGDs. Discussions were recorded, translated, transcribed verbatim and analyzed using content analysis.

RESULTS

Three themes were identified from the emerging analysis. These are, 1) Knowledge and risk perceptions about STIs and HPV, 2) Beliefs and attitudes towards HPV prevention, 3) Participant's recommendations for HPV vaccination and anal Pap screening. Participants described lack of knowledge of HPV and its health consequences as HIV is the only focus of attention of the government and the local CBOs. None of participants had heard about HPV prevention including vaccination and anal Pap screening for men but expressed a positive attitude towards prevention. Genital warts and anal cancer were perceived as severe potential consequences of a known risk behaviors. All participants stated they would be interested in taking an HPV vaccine but acknowledged that the provision of services for sexually transmitted infections (STI) are inadequate to meet the needs of key populations and are not prioritized by the government. The main perceived barriers to access HPV prevention included cost and challenges to access public health care services or openly discussing one's sexual orientation with health care providers. Participants generally preferred the CBO for more professional, unbiased staff attitudes that respect patients' integrity, confidentiality and privacy. Most participants thought that in case the government is non-cooperative, CBOs should work in the interest of HPV eradication and generate funds through international funding.

CONCLUSIONS

The findings from this study can help public health policy and researchers to understand this minority's perspective on HPV prevention. Given the low level of knowledge about HPV infection and its negative health consequences there is a need of HPV education combined with STI education and awareness through HPV brochures to educate the target population effectively.

Reported rationales for HPV vaccination vs. Non-vaccination among undergraduate and medical students in South Carolina

Objective: We sought to identify factors that influence Human Papillomavirus (HPV) vaccination rates in individuals at two higher education institutions in South Carolina (SC).Participants: We surveyed 1007 students with a mean age and standard deviation of 20.3 ± 3.3 from September 2018 to December 2018.Methods: Participants answered 13 questions, assessing HPV vaccination rates, demographics, and rationales for vaccination vs. non-vaccination.Results: Of 1007 respondents, 700 received HPV vaccination, 165 were unvaccinated, 75 received partial vaccination and 138 were uncertain. Commonalities in HPV vaccination existed between females (p = 0.037), individuals who received standard childhood vaccinations (p = 0.04), and those not native-born in SC (p < 0.001). Of non-vaccinated individuals, 37% "never thought about vaccination," 32% did not perceive a need for vaccination, and 31% reported vaccine safety as reasons for not receiving the vaccine.Conclusions: Promotion of HPV vaccination may benefit from targeting SC natives, males, and individuals who are under-vaccinated or unvaccinated.

"We fear the unknown": Emergence, route and transfer of hesitancy and misinformation among HPV vaccine accepting mothers

Although licensed since 2006, US HPV vaccination rates remain suboptimal. Since mothers are decision-makers for young adults' vaccination, assessing ongoing knowledge deficits and misunderstanding among parents is important for determining the content and mode of interventions to reach parents. Guided by the social-ecological model and health belief model, 30 interviews with vaccine accepting mothers in the U.S. Midwest were conducted from January through June 2020. Researchers examined ecological determinants of acceptance, perceptions of vaccination barriers, and perceived cues to action for empowering other mothers to vaccinate their children. Data were analyzed using thematic analysis. Results found vaccine accepting mothers exhibited ongoing misconceptions and negative attitudes toward HPV vaccine. Physicians, peers and the media were identified as primary pro-HPV vaccine sources, yet hesitancy and misinformation occurred with each source. Trust in provider recommendation was the primary source for decision-making, yet trust was still lacking. While mothers looked to the media for HPV information, the media were identified as the main source of confusion and distrust. Results show that parents who accept the HPV vaccine can still be hesitant. Thus, mothers who have vaccinated their children for HPV may still need attitudinal and educational training prior to establishing them as role models in interventions for empowering other parents to vaccinate their children. Results showing that the media sow confusion and hesitancy also call for more attention to social media policies to guard against misinformation about the HPV vaccine.

Knowledge and Behavior of University Students toward Human Papillomavirus and Vaccination

Objectives:

Human papillomavirus (HPV) causes cervical cancer. This study aimed to determine the knowledge and attitude of university students toward HPV infection and vaccine prevention in Turkey.

Methods:

A total of 1563 female and male university students participated in the study. The study design was descriptive and cross-sectional. The study included students enrolled in the departments of faculties and vocational schools.

Results:

In total, 16.8% of students stated that they had heard of HPV. There was a statistically significant relationship between the mean awareness of HPV and different variables, such as age, gender, marital status, family history of cancer, and conversation about sexual matters (P < 0.01). As the age of the students increased, the chance of hearing about HPV also increased. Of all the students, 1.5% took HPV vaccination. Furthermore, 87.7% of the female students stated that they had heard of cervical cancer.

Conclusions:

The depth of knowledge among Turkish university students toward cervical cancer, HPV infection, and vaccination was inadequate. It is important to provide educational and counseling services by nurses to make university students aware of HPV infection and vaccination.

Attitudes to HPV Vaccination among Parents of Children Aged 10 to 13 Years

STUDY OBJECTIVE

This study aimed to determine the willingness of parents to allow their sons and/or daughters aged 10-13 years to be vaccinated for human papillomavirus (HPV).

DESIGN, SETTING, AND PARTICIPANTS

This was a descriptive study conducted in an elementary school to recruit students' parents into the study. The sample consisted of 368 (69.1%) parents of children aged 10-13 years who were willing to participate in the study as a couple.

INTERVENTIONS

Questionnaire-based data were collected from the couples.

MAIN OUTCOME MEASURES

Prior information regarding HPV and vaccination and the opinions of parents of children aged 10-13 about HPV vaccination for their daughter or son.

RESULTS

Only 26.9% of mothers and 25.0% of fathers claimed to be aware of HPV, and only 24.5% of mothers and 21.2% of fathers claimed to be aware of its vaccine. If the vaccine were available in Turkey, 21.6% of mothers and 22.4% of fathers would be willing to vaccinate their sons; although the vaccine for girls is available in Turkey, only 14.4% of mothers and 15.5% of fathers were willing to vaccinate their daughters.

CONCLUSIONS

Few participants reported knowing about the HPV vaccine, while far fewer intended to vaccinate their daughters and sons against the infection. Both males and females should be informed about HPV and its vaccine, and initiatives to increase both awareness and the information of health care professionals should be encouraged.

Parental attitudes towards male human papillomavirus vaccination: a pan-European cross-sectional survey

Background

Human papillomavirus (HPV) is a common sexually transmitted virus that can lead to severe diseases in both women and men. Today, HPV vaccination is offered to females only across Europe. We aimed to examine parental attitudes to HPV vaccination of their sons given brief information about HPV in both genders.

Methods

A literature study on acceptability of male HPV vaccination was carried out to inform the construction of a study questionnaire. Following up on a Danish study from 2012, this questionnaire was applied in 1837 computer assisted interviews with parents of sons in the UK, Germany, France and Italy. In each country, the parents were representative in terms of geographical dispersion, city size and age of sons in the household. The applied questionnaires took the varying vaccination policies and delivery systems into account. The data were analysed pooled and for each country using significant statistical tests (chi-2) with a 95 % confidence interval.

Results

Approximately ¾ of parents in the UK, Germany and Italy were in favour of HPV vaccination of their sons. In France, this applied to 49 % of respondents. Favourable parents wanted to protect their sons from disease and found gender equality important. Parents in doubt about male HPV vaccination needed more information about HPV diseases in men and male HPV vaccination; Rejecting parents were generally sceptical of vaccines and feared vaccination side-effects. Parents in countries with active vaccination policies (UK and Italy) tended to trust the importance of national vaccination programmes. Parents in countries with passive vaccination strategies (Germany and France) had greater need for information from health care professionals (HCP) and public health authorities.

Conclusion

Given brief information about HPV in both genders, parental acceptance of HPV vaccination of sons is as high as acceptance levels for girls. All parents should be informed about HPV to make informed decisions about HPV vaccination for their children. There is a need for joint efforts from public health authorities and HCPs to provide parents with such information.

Human papillomavirus vaccines and cervical cancer: awareness, knowledge, and risk perception among Turkish undergraduate students

The aim of this study was to evaluate awareness, knowledge, and risk perception about human papillomavirus (HPV), cervical cancer, and HPV vaccines among undergraduate students in Turkey. The convenience sample of this descriptive cross-sectional study consisted of 605 undergraduate students in Istanbul University during a semester. Demographic characteristics of students, their reproductive health and lifestyle behaviors, and knowledge of HPV and HPV vaccine were questioned using self-administered forms. The overall proportion of students who had heard about HPV infection was 48.8%, while the proportion of students who had heard of the HPV vaccine was 44.5%. Forty eight percent of females and 60% of males reported never having heard of the HPV. Only 45.7% of females had knowledge about HPV as a cause of genital warts, and 58.1% correctly indicated that HPV caused cervical cancer. The majority of students in both genders (>80%) knew that the infection is primarily transmitted through sexual intercourse. Females were more concerned than males about having cervical/penile cancer associated with HPV in the future. Only 46.4% of females and 39% of males reported having heard of the HPV vaccine. The majority of the female and male students did not know who should get the HPV vaccine and when to get vaccinated. Among males, 25.8% reported that they would consider getting vaccinated (if available) and 38.4% intended to vaccinate their children. Turkish undergraduate students had a low to moderate level of knowledge regarding HPV infection and HPV vaccine. In order to increase awareness about HPV and develop positive behaviors, young people should be provided with accurate information through educational activities in the community and health care services.

Ethnic and gender differences in HPV knowledge, awareness, and vaccine acceptability among White and Hispanic men and women

The purpose of this study was to examine factors associated with human papillomavirus (HPV) knowledge and awareness, and HPV vaccination among White and Hispanic males and females. Differences in HPV knowledge, sources of information, vaccine awareness, vaccination status, and interest in vaccination were examined. A community sample was recruited from local health care clinics in a medium sized Midwestern city between May 2010 and December 2011. Participants (N = 507) were White (n = 243) and Hispanic, males (n = 202) and females between the ages of 15-30. Results indicate that White and female participants were significantly more likely to have heard of HPV, have higher levels of HPV knowledge, have been diagnosed with HPV, and be aware of the HPV vaccine for women. White and female participants were also more likely to have heard of HPV from their physician and were significantly more interested in receiving the HPV vaccine in the future. There was no effect of ethnicity on interest in the vaccine per a doctor's recommendation, however. Findings suggest that Whites and females have greater levels of HPV awareness and knowledge and that, while Hispanic participants are less likely than White participants to be told about the HPV vaccine from their provider, they may be equally receptive to such a recommendation.

Promoting HPV prevention in the school setting

In pediatrics especially, it is important to incorporate the latest immunization and Healthy People 2020 guidelines while working to promote health and prevent disease in children. Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States with at least 20 million people infected. Consequently, approximately 18,000 women and 7,000 men are diagnosed with HPV associated cancers yearly. Gardasil is a quadrivalent vaccine that protects against HPV strains 6, 11, 16, and 18. It is currently recommended by the Advisory Committee on Immunization Practices for both males and females between 11 and 26 years of age. HPV immunization rates are lower than the intended 80% goal of Healthy People 2020, with only 26.7% of the population having completed the vaccination series. Focused, timely, and persistent education and prevention efforts are needed in school settings to increase vaccination rates and decrease HPV morbidity.

Awareness and knowledge of human papillomavirus (HPV) infection among high-risk men of Hispanic origin attending a sexually transmitted infection (STI) clinic

Background

Genital Human papilloma virus (HPV) is one of the most commonly diagnosed Sexually Transmitted Infection (STIs) in men and women. Knowledge about HPV infection among men is limited. This study aims to determine correlates of adequate knowledge of HPV infection among men who attend an STI clinic in Puerto Rico.

Methods

A cross-sectional study of 206 men was conducted at an STI clinic in San Juan, PR. Adequate knowledge was defined as a score of at least 70% of correct responses among those men who reported having ever heard of HPV. Variables that achieved statistical significance in the bivariate analysis (p<0.05) were included in the multivariate logistic regression model.

Results

Although 52.5% of men reported having heard of HPV infection before the survey, only 29.3% of this sub-group had an adequate knowledge of HPV. Most men did not know that HPV is a risk factor for anal (38.7%), penile (50.0%) and oral (72.6%) cancer. Factors associated with adequate knowledge of HPV in age-adjusted models were being men who have sex with men (MSM) (OR=2.6;95%CI=1.1-6.1), self-report of genital warts (OR=3.2;95%CI=1.3-7.9) and herpes (OR=7.4;95% CI=2.2-25.1). MSM was marginally associated with adequate knowledge (OR=2.3;95% CI=0.9-5.9) and self-report of herpes remained significantly associated (OR=5.0;95%CI=1.3-18.4) in multivariate logistic regression analysis.

Conclusions

Awareness and knowledge of HPV was very low in this group of men. Interventions to increase knowledge and awareness in this group are necessary to promote preventive practices for HPV-related cancers in high-risk groups.

Gay and bisexual men’s human papillomavirus vaccine intentions: A theory-based structural equation analysis

In this study, we examined the structural relationships among constructs from the Health Belief Model as they relate to human papillomavirus vaccine intentions in young gay and bisexual men in the United States ( N = 183). A model was identified that fit the data well and accounted for 56% of the variance in vaccine intentions. Perceived benefits and barriers were the most proximate predictors of intentions, whereas knowledge and perceived threat exerted only indirect influence. Clarifying the propositional structures within the Health Belief Model can help to advance our understanding of human papillomavirus–related cognitions and behaviors and inform vaccine promotion programs.
