Views on HPV and HPV Vaccination: The Experience at a Federal Qualified Clinic in Puerto Rico

Latinx fathers report low awareness and knowledge of the human papillomavirus vaccine, but high willingness to vaccinate their children if recommended by a healthcare provider: A qualitative study

This descriptive qualitative study explored Latinx fathers' awareness, knowledge, and acceptability of the human papillomavirus (HPV) vaccine for their adolescent children. Data were collected through individual, semi-structured interviews and analysed using a hybrid method of thematic analysis that incorporated deductive and inductive approaches. Nineteen, majority foreign-born Latinx fathers participated. Four main themes and two subthemes emerged from the analyses. Results found fathers' low awareness and knowledge of HPV and the HPV vaccine. Results also identified fathers' positive attitudes toward vaccines in general. Moreover, results revealed fathers trust in healthcare providers and high willingness to vaccinate their children against HPV if recommended by their child's primary healthcare provider. Findings indicate the need for increased efforts to raise awareness and knowledge among Latinx fathers of HPV and the HPV vaccine. Given the limited research focused on Latinx fathers, the study's findings are valuable in building a knowledge foundation for developing future studies and interventions to promote the HPV vaccine targeting Latinx fathers living in the United States. Future research should quantify Latinx fathers' awareness, knowledge, and acceptability of the HPV vaccine for their sons and daughters and assess fathers' role in the decision-making process to vaccinate their children against HPV.

Sex and educational attainment differences in HPV knowledge and vaccination awareness among unvaccinated-sexually active adults in Puerto Rico

Human papillomavirus (HPV) knowledge and HPV vaccination uptake remain suboptimal. We assessed sex and educational attainment differences in HPV knowledge and vaccine awareness. Data from a cross-sectional study (2018–2021) in Puerto Rico among adults aged 21–49 was analyzed (n = 278). Adequate knowledge was defined as a score of ≥70% of correct responses on a 13-item knowledge scale. Multivariable logistic regression was used to assess the association of sex (men vs. women) and education (high school or less vs. more than high school) categories with adequate HPV knowledge and vaccine awareness. Adequate HPV knowledge was higher among women (53%) and men (46%) with more than high school and was lower among women (46%) and men (27%) with high school or less. For HPV vaccine awareness, similar results were observed. Women (OR = 3.0 ; 95%CI = 1.4–6.2) and men (OR = 2.3 , 95%CI = 1.1–4.8) with more than high school and women with high school or less (OR = 2.3 , 95%CI = 1.0–5.2) were more likely to have adequate HPV vaccine knowledge than men with high-school or less education. Heightened HPV vaccine awareness was also seen among more educated women and men and women with similar lower education when compared to men with ≤ high school. Men and individuals with lower educational attainment were more likely to have inadequate HPV knowledge and vaccine awareness. HPV vaccine-oriented educational interventions should target these high-risk groups.

Disparities in Healthcare Providers' Recommendation of HPV Vaccination for U.S. Adolescents: A Systematic Review

Infrequent provider recommendations continue to be a key barrier to human papillomavirus (HPV) vaccination, including among adolescents at higher risk for future HPV cancers. To inform future interventions, we sought to characterize disparities in health care providers' HPV vaccine recommendation for U.S. adolescents. We systematically reviewed studies published in 2012-2019 that assessed provider HPV vaccine recommendations for adolescents aged 9-17. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we identified 52 eligible studies and used a standardized abstraction form to assess recommendation prevalence by adolescent demographic characteristics. Studies consistently found that fewer parents of boys than girls reported receiving HPV vaccine recommendations (14 studies, range of difference: -11 to -35 percentage points). Studies also found fewer recommendations for adolescents who were younger (2 studies, -3% to -12% points), non-White (3 studies, -5% to -7% points, females only), lower income (3 studies, -1% to -8% points), or uninsured (1 study, -21% points, males only). Studies identified geographic disparities in southern and rural areas. In conclusion, findings from this systematic review identify disparities in HPV vaccine recommendation that may contribute to suboptimal vaccine uptake. Efforts to improve providers' HPV vaccine communication should focus on increasing recommendation consistency, especially for lower-income, non-White, and rural adolescents.

Provider communication and HPV vaccine uptake: A meta-analysis and systematic review

Provider communication can be critically important to families as they consider HPV vaccination. We sought to characterize the association of provider communication and HPV vaccine uptake, and when communication better motivates vaccination. We searched four databases for studies published between 2006 and 2019. Eligible studies examined health care provider communication (defined as recommendation or discussion) and HPV vaccine uptake (defined as initiation, completion, or follow-through) in the US. Two coders independently identified eligible studies and coded effect sizes and study characteristics. We pooled effect sizes using random-effects meta-analysis. We identified 59 eligible studies of 265,083 patients. Receiving a provider recommendation was associated with higher HPV vaccine initiation (pooled OR = 10.1, 95% CI: 7.6-13.4). HPV vaccine initiation was 24% for patients without and 60% for patients with a provider recommendation. The pooled effect size for provider recommendation and initiation was smaller for probability samples, clinical records, and NIS-Teen (all p < 0.002). Recommendations were equally effective for males and females, for different patient ages, and over time. Provider recommendation was also associated with higher HPV vaccine series completion and follow-through. Provider discussion was similarly associated with higher HPV vaccine initiation (OR = 12.4, 95% CI: 6.3-24.3). In summary, provider communication was robustly associated with HPV vaccination initiation, completion, and follow-through. These findings suggest that US public health efforts to increase HPV vaccine coverage should continue to emphasize provider communication.

Perceived Barriers and Trends in HPV Vaccination via Patient Survey Responses at Kalamazoo, Michigan's Federally-Qualified Health Center

Human Papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the United States. Despite numerous studies proving the safety and efficacy of the HPV vaccine, immunization rates remain low, especially among underserved populations. To identify factors contributing to low HPV vaccination rates, patients at a federally qualified health center in Kalamazoo MI were surveyed. Surveys were administered during routine patient visits to determine self-reported vaccination status and vaccination barriers. A total of 98 vaccine-eligible (males/females, ages 9-26 years old) patients/guardians completed the survey. In all, 46% of respondents completed the multi-dose vaccination course, and 56% of those identified as female. White patients reported higher vaccination rates (50%) than patients of color (45%). Of those vaccinated, the most common reason was "physician recommendation" (39%). Those not fully vaccinated most commonly reported being "too young" (39%). Importantly, individuals who had begun, but not completed, the vaccination course reported that their provider had not spoken to them about future vaccines in the series (74%). This study revealed disparities in vaccination rates between the sexes and racial groups, and emphasized the influential role of physician's recommendation on vaccination. Interestingly, other frequently cited barriers to vaccination-an association with sex, personal/religious beliefs, efficacy-proved to be insignificant barriers for this population. Instead, age-related misunderstandings and lack of consistent physician communication about vaccination provided significant barriers. Based on our results, education and reminders about the HPV vaccine by providers is a significant tool to maximize vaccination coverage.

Resources for assessing parents' vaccine hesitancy: a systematic review of the literature

The concept of Vaccine Hesitancy has begun to appear in the scientific landscape, referring to the reluctance of a growing proportion of people to accept the vaccination offer. A variety of factors were identified as being associated with vaccine hesitancy but there was no universal algorithm and currently there aren’t any established metrics to assess either the presence or impact of vaccine hesitancy. The aim of this study was to systematically review the published questionnaires evaluating parental vaccine hesitancy, to highlight the differences among these surveys and offer a general overview on this matter. This study offers a deeper perspective on the available questionnaires, helping future researches to identify the most suitable one according to their own aim and study setting.

Central American Immigrant Parents' Awareness, Acceptability, and Willingness to Vaccinate Their Adolescent Children Against Human Papillomavirus: A Pilot Cross-Sectional Study

Despite increasing interest in understanding the factors influencing awareness and acceptability of the human papillomavirus (HPV) vaccine among Latino parents, to date limited information is available specific to Central American parents living in the United States (US). Therefore, this pilot cross-sectional study was designed to explore and assess Central American immigrant parents’ awareness, acceptability, and willingness to vaccinate their children against HPV, and interest in participating in future HPV-associated cancer prevention study. Fifty-six Central American parents, majority immigrant (96.4%; n = 54) from four countries, El Salvador—50% (n = 27); Guatemala—25.9% (n = 14); Honduras—22.2% (n = 12); and Panama—1.9% (n = 1) participated in this study. Participants completed an interviewer-administered questionnaire survey in their preferred language (i.e., Spanish or English). A little over half of the participants were mothers (57.1%; n = 32) and parents’ mean age was 43.2 years (SD = 6.4). The majority was married or cohabitating (76.8%, n = 43), and 39.3% (n = 22) reported having two children. Seventy-five percent (n = 42) of parents reported they had heard of the HPV vaccine. Fewer fathers were aware of the HPV vaccine (58.3%; n = 14 vs.87.5%, n = 28; p = 0.01) than mothers. Among parents who had heard of the HPV vaccine (n = 42), 85.7% (n = 36) reported their children had received at least one dose of the HPV vaccine. Fewer fathers reported their child had been vaccinated against HPV (64.3%, n = 9 vs. 96.4%, n = 27; p = 0.06) than mothers. Moreover, 90% of parents (n = 18) whose children were unvaccinated reported willingness to vaccinate their adolescent children against HPV if recommended by their child’s physician. Findings indicate parents’ low to moderate awareness of the HPV vaccine, and high willingness to vaccinate their adolescent children if recommended by their child’s physician. Findings also demonstrate fathers’ lower awareness and acceptability of the HPV vaccine than mothers. Despite limitations and the need for more research, findings of this pilot study serve as a valuable first step toward building a knowledge foundation that is needed for developing future studies and interventions targeting Central American immigrant parents living in the US. Future studies can build on the findings of this exploratory study with other research designs and address its limitations by having a larger sample size and accounting for additional factors associated with Central American immigrant parents’ HPV awareness, knowledge, beliefs, attitudes, and vaccine acceptability from other communities across the US.

Brazilian Immigrant Parents' Awareness of HPV and the HPV Vaccine and Interest in Participating in Future HPV-Related Cancer Prevention Study: an Exploratory Cross-Sectional Study Conducted in the USA

This exploratory community-based study assessed Brazilian immigrant parents' awareness of HPV and the HPV vaccine, HPV information sources, and their interest in participating in a future HPV-related cancer prevention study. This study is a cross-sectional analysis of data from a convenience sample of Brazilian immigrant parents living in selected cities in Massachusetts. Participants completed a brief survey in their language of preference (English or Portuguese) administered by bilingual interviewers. Forty-seven Brazilian immigrant parents, each representing a unique family, participated in the study. All participants completed the survey in Portuguese. Although the majority reported being aware of HPV (93.6%, n = 44), only 74.5% (n = 35) were aware of the HPV vaccine. Fewer fathers than mothers had heard of the HPV vaccine (61.9%; n = 13 vs. 84.6%, n = 22; p = 0.04). Of those who were aware of the HPV vaccine (n = 35), 82.6% (n = 29) reported hearing about the HPV vaccine from their child's physician. Additionally, nearly all participants (97.9%, n = 46) reported being interested in participating in future HPV-related cancer prevention study. Findings of this exploratory study indicate parents' low to moderate awareness of the HPV vaccine and high interest in participating in future HPV-related cancer prevention study. These findings are important and serve as a valuable first step toward building a knowledge foundation that is critically needed for developing future studies targeting Brazilians immigrant parents and adolescents living in the USA.

Exploring HPV Knowledge, Awareness, Beliefs, Attitudes, and Vaccine Acceptability of Latino Fathers Living in the United States: An Integrative Review

To conduct an integrative review to identify and synthesize studies exploring human papillomavirus (HPV) knowledge, awareness, beliefs, attitudes, and acceptability of the HPV vaccine among Latino fathers living in the United States. The review methodology was informed by those developed by Whittemore and Knafl, which allow for the inclusion of qualitative, quantitative, and mixed methods studies. Using the preferred reporting items for systematic reviews meta-analyses guidelines, five electronic databases (PubMed, Medline, PsycINFO, CINAHL, Science Direct) were searched for peer-reviewed, full-text studies published in English with samples that included Latino fathers and examined knowledge, awareness, beliefs, attitudes about the HPV and the HPV vaccines. Studies that did not provide information on the inclusion of fathers in the sample were excluded. Identified eligible studies were analyzed and synthesized using the matrix method. Eleven eligible studies were identified. Most (n = 10) included mothers and fathers. One study included only fathers, and this study determined that although fathers held positive attitudes toward the HPV vaccine, a notable number of participants were unsure of or had not formed an opinion about the HPV vaccine. Fathers felt that a recommendation from their child's physician would impact whether they vaccinated their child. Moreover, of the ten studies including both parents, only two specifically compared fathers' and mothers' knowledge and awareness about the HPV and vaccine acceptability. These two studies determined that fathers were less aware of the HPV and had lower HPV vaccine-related knowledge than mothers. Nevertheless, all of the 11 examined studies, found moderate to high acceptability of the HPV vaccine among Latino parents despite uncertainty about possible vaccine risks and costs. Only 11 studies were identified that included Latino fathers. Of these studies, only one was conducted exclusively with Latino fathers and two compared fathers and mothers. Additional research focusing on Latino fathers is needed given the central role of the family in the Latino culture and the shared role fathers and mothers have in decision-making related to their children's health.

Parents' uptake of human papillomavirus vaccines for their children: a systematic review and meta-analysis of observational studies

OBJECTIVE

To examine factors associated with parents' uptake of human papillomavirus (HPV) vaccines for their children.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Cochrane Library, AIDSLINE, CINAHL, EMBASE, PsycINFO, Social Sciences Abstracts, Ovid MEDLINE, Scholars Portal, Social Sciences Citation Index and Dissertation Abstracts International from inception through November 2017.

METHODS

We included studies that sampled parents and assessed uptake of HPV vaccines for their children (≤18 years) and/or sociodemographics, knowledge, attitudes or other factors associated with uptake. Study risk of bias was assessed using the Effective Public Health Practice Project tool. We pooled data using random-effects meta-analysis and conducted moderation analyses to examine variance in uptake by sex of child and parent.

RESULTS

Seventy-nine studies on 840 838 parents across 15 countries were included. The pooled proportion of parents' uptake of HPV vaccines for their children was 41.5% (range: 0.7%-92.8%), twofold higher for girls (46.5%) than for boys (20.3%). In the meta-analysis of 62 studies, physician recommendation (r=0.46 (95% CI 0.34 to 0.56)) had the greatest influence on parents' uptake, followed by HPV vaccine safety concerns (r=-0.31 (95% CI -0.41 to -0.16)), routine child preventive check-up, past 12 months (r=0.22 (95% CI 0.11 to 0.33)) and parents' belief in vaccines (r=0.19 (95% CI 0.08 to 0.29)). Health insurance-covered HPV vaccination (r=0.16 (95% CI 0.04 to 0.29)) and lower out-of-pocket cost (r=-0.15 (95% CI -0.22 to -0.07)) had significant effects on uptake. We found significant moderator effects for sex of child.

CONCLUSIONS

Findings indicate suboptimal levels of HPV vaccine uptake, twofold lower among boys, that may be improved by increasing physician recommendations, addressing parental safety concerns and promoting parents' positive beliefs about vaccines, in addition to expanding insurance coverage and reducing out-of-pocket costs. Limitations of this meta-analysis include the lack of intervention studies and high risk of bias in most studies reviewed. Further studies should disaggregate HPV vaccine uptake by sex of child and parent.
