Acceptability of the human papillomavirus vaccine among Latina mothers

Factors influencing human papillomavirus school-based immunization in Alberta: A mixed-methods study protocol

More than 1,300 Canadians are diagnosed with cervical cancer annually, which is nearly preventable through human papillomavirus (HPV) immunization. Across Canada, coverage rates remain below the 90% target set out by the Action Plan for the Elimination of Cervical Cancer in Canada (2020-2030). To support this Plan, the Canadian Partnership Against Cancer has commissioned the Urban Public Health Network (UPHN) to coordinate a quality improvement project with Canada's school-based HPV immunization programs. In Alberta, the UPHN partnered with Alberta Health Services (AHS) for this work. This study has one overarching research question: what are parent/guardian and program stakeholder perceived barriers, enablers and opportunities to immunization for youth as part of the school-based HPV immunization program in Alberta? This study uses a mixed-methods sequential explanatory design. A survey will be emailed to a sample of Albertans with children aged 11-17 years. Questions will be based on a Conceptual Framework of Access to Health Care. Subsequent qualitative work will explore the survey's findings. Parents/guardians identifying as vaccine hesitant in the survey will be invited to participate in virtual, semi-structured, in-depth interviews. Stakeholders of the school-based immunization program will be purposively sampled from AHS' five health zones for virtual focus groups. Quantitative data will be analyzed using SAS Studio 3.6 to carry out descriptive statistics and, using logistic regression, investigate if Framework constructs are associated with parents'/guardians' decision to immunize their children. Qualitative data will be analyzed using NVivo 12 to conduct template thematic analysis guided by the Framework. Study results will provide insights for Alberta's public health practitioners to make evidence-informed decisions when tailoring the school-based HPV immunization program to increase uptake in vaccine hesitant populations. Findings will contribute to the national study, which will culminate in recommendations to increase HPV immunization uptake nationally and progress towards the 90% coverage target.

Sexual behaviour, human papillomavirus and its vaccine: a qualitative study of adolescents and parents in Andalusia

BACKGROUND

Human papillomavirus (HPV) is one of the most common sexually transmitted infections and can be prevented by vaccination. The purpose of this study is to gain a better understanding, by analysing interview responses of adolescents and parents, of how adolescent sexual behaviour is approached in families, how widespread knowledge about HPV is in Andalusia, the autonomous region with the lowest vaccination rate in Spain, as well as to learn more about the interviewees' position regarding vaccination.

METHODS

A qualitative study by means of 15 focus groups of adolescents (N = 137, aged 14-17 years) and five focus groups of parents with children of those ages (N = 37) was conducted in the provinces of Granada, Seville and Jaén (Andalusia, Spain). The audio data were transcribed verbatim, coded and analysed thematically using NVIVO-10 software.

RESULTS

There were three major results: (1) There is a lack of communication between adolescents and parents regarding sexual behaviour; (2) In both groups, scarce knowledge about HPV and vaccination was found; (3) Parents mistrust vaccination due to a lack of qualified and verified information about its benefits.

CONCLUSIONS

Healthy adolescent sexual behaviour is aided by communication within the family. Families need more information based on the evidence about HPV and vaccination. Health professionals are a key element in this process.

Cervical cancer, human papillomavirus (HPV), and HPV vaccination: exploring gendered perspectives, knowledge, attitudes, and cultural taboos among Mexican American adults

Background: Gendered perspectives may be particularly important in shaping norms and values around HPV and HPV vaccination, as previous research suggests that sexuality taboos (e.g. promiscuity) may contribute to low perceived risk among adolescent and young adult Hispanic females. However, research to date focuses primarily on Hispanic mothers, adolescent females, and women of HPV vaccine-eligible age. Hispanic father's perspectives are relatively unknown despite father's important role in shaping norms for their female children. Objective: To close this gap, this study examines gendered perspectives in knowledge, beliefs, and attitudes about HPV and HPV vaccination from Hispanic parents (mothers and fathers), women of vaccine-eligible age (18-26 years old), and women eligible for Pap Test screening (>26 years old) living in two counties along the Texas-Mexico border. Design: We conducted eight focus groups. Research staff transcribed audio recordings verbatim and uploaded them into Atlas(ti) 5.0 for analysis. The research team analyzed the data for content, meaning, patterns and themes using the constant comparison approach. Results: Perspectives were highly gendered. Women's (all groups combined) beliefs focused on misconceptions around how the HPV virus is contracted (e.g. toilet surfaces). Women also linked HPV-related sexual risk to adultery and indiscretion of male partners. Fathers (men) were more likely to link risk to female promiscuity. Fathers also worried that HPV vaccination might increase promiscuity. All groups believe that HPV vaccination is a way to protect Hispanic females in the face of beliefs around sexual behavior and risk of contracting HPV. Conclusion: Results suggest gendered differences in risk beliefs concerning HPV among Hispanics living along the Texas-Mexico border. Researchers can use these findings to address barriers to HPV vaccination, as well as to create culturally appropriate prevention messages that may help reduce disparities in HPV among Hispanic women.

Acceptability of the human papillomavirus vaccine in schools in Lusaka in Zambia: Role of community and formal health system factors

Zambia has one of the highest cervical cancer rates in the world. This paper explores the acceptability of the Human Papillomavirus vaccine administered in girls (9-13 years) in Zambia. A qualitative case study was conducted in two schools in Lusaka district, which participated in the pilot for the Human Papillomavirus vaccine rollout. The study revealed that community level health systems factors such as knowledge levels about the vaccine, sexual morality concerns, conflicting views from parents on the vaccine, rumours that the vaccine contained cervical cancer and that it causes infertility in girls, previous bad experience with other vaccines, religious beliefs such as belief that God protects against illness, the nature of the school environment as well as faith in doctors shaped the uptake of the vaccine. Furthermore, formal health system factors such as availability of health workers and nature of collaboration between the Ministries of Health and Education influenced acceptability of the vaccine among the girls. Strengthening collaboration between community and formal health systems can play a vital role in supporting uptake of vaccines at community level as factors that hinder uptake of the vaccines emanate from both the community and health sector.

Vaccipack, A Mobile App to Promote Human Papillomavirus Vaccine Uptake Among Adolescents Aged 11 to 14 Years: Development and Usability Study

BACKGROUND

More than 90% of human papillomavirus (HPV)-related cancers could be prevented by widespread uptake of the HPV vaccine, yet vaccine use in the United States falls short of public health goals.

OBJECTIVE

The purpose of this study was to describe the development, acceptability, and intention to use the mobile app Vaccipack, which was designed to promote uptake and completion of the adolescent HPV vaccine series.

METHODS

Development of the mobile health (mHealth) content was based on the integrated behavioral model (IBM). The technology acceptance model (TAM) was used to guide the app usability evaluation. App design utilized an iterative process involving providers and potential users who were parents and adolescents. App features include a vaccine-tracking function, a discussion forum, and stories with embedded messages to promote intention to vaccinate. Parents and adolescents completed surveys before and after introducing the app in a pediatric primary care setting with low HPV vaccination rates.

RESULTS

Surveys were completed by 54 participants (20 adolescents aged 11 to 14 years and 34 parents). Notably, 75% (15/20) of adolescents and 88% (30/34) of parents intended to use the app in the next 2 weeks. Acceptability of the app was high among both groups: 88% (30/34) of parents and 75% (15/20) of adolescents indicated that Vaccipack was easy to use, and 82% (28/34) of parents and 85% (17/20) of adolescents perceived the app to be beneficial. Higher levels of app acceptability were found among parents with strong intentions to use the app (P=.09; 95% CI -2.15 to 0.15).

CONCLUSIONS

mHealth technology, such as Vaccipack, may be an acceptable and nimble platform for providing information to parents and adolescents and advancing the uptake of important vaccines.

Beliefs around childhood vaccines in the United States: A systematic review

BACKGROUND

While childhood vaccines are safe and effective, some parents remain hesitant to vaccinate their children, which has led to outbreaks of vaccine preventable diseases. The goal of this systematic review was to identify and summarize the range of beliefs around childhood vaccines elicited using open-ended questions, which are better suited for discovering beliefs compared to closed-ended questions.

METHODS

PubMed, Embase, and PsycINFO were searched using keywords for childhood vaccines, decision makers, beliefs, and attitudes to identify studies that collected primary data using a variety of open-ended questions regarding routine childhood vaccine beliefs in the United States. Study designs, population characteristics, vaccine types, and vaccine beliefs were abstracted. We conducted a qualitative analysis to conceptualize beliefs into themes and generated descriptive statistics.

RESULTS

Of 1727 studies identified, 71 were included, focusing largely on parents (including in general, and those who were vaccine hesitant or at risk of hesitancy). Seven themes emerged: Adverse effects was most prominent, followed by mistrust, perceived lack of necessity, pro-vaccine opinions, skepticism about effectiveness, desire for autonomy, and morality concerns. The most commonly described beliefs included that vaccines can cause illnesses; a child's immune system can be overwhelmed if receiving too many vaccines at once; vaccines contain harmful ingredients; younger children are more susceptible to vaccine adverse events; the purpose of vaccines is profit-making; and naturally developed immunity is better than that acquired from vaccines. Nearly a third of the studies exclusively assessed minority populations, and more than half of the studies examined beliefs only regarding HPV vaccine.

CONCLUSIONS

Few studies used open-ended questions to elicit beliefs about vaccines. Many of the studies that did so, focused on HPV vaccine. Concerns about vaccine safety were the most commonly stated beliefs about childhood vaccines, likely because studies were designed to capture barriers and challenges to vaccination.

Perception about barriers and facilitators of the school-based HPV vaccine program of Manizales, Colombia: A qualitative study in school-enrolled girls and their parents

In 2012, Colombia implemented a school-based HPV vaccination program of a 3-dose series for nine year old girls. Following a mass psychogenic response after vaccination in a Colombian town, vaccination rates dropped from 80% in 2012-2013 to 5% in 2016. The study aimed to identify barriers and facilitators of HPV vaccine uptake among girls eligible for vaccination in the initial years of vaccine implementation from 2012 to 2014, and their parents. We conducted 19 individual qualitative interviews and 18 focus groups with an average of 5 girls, in Manizales, Colombia between 2016 and 2017. In total, 49 girls from six schools and 58 of their parents participated in the study. Participants had some degree of awareness about cervical cancer, especially among those of middle and upper socioeconomic level. However, the vaccine was known as a prevention measure only after pap-smears and condoms. The main facilitator for vaccine uptake for parents was the desire to prevent diseases in general and for girls, it was facilitated by receiving positive information about the vaccine. The main barriers for vaccine uptake or for three doses completion were the event in Carmen de Bolivar, fear of adverse effects and fear of needles. Girls and parents stated that they received little or no information from schools or health care services about the HPV vaccine prior to vaccination. Our results suggest that improving HPV vaccination rates in Colombia will require a comprehensive education program including mass media information about HPV vaccine.

HPV Vaccine recommendations: does a health care provider's gender and ethnicity matter to Unvaccinated Latina college women?

Objectives: There are disparities in the uptake of HPV vaccine among racial/ethnic minority women. The strongest predictor of HPV vaccine uptake among adult women is health care provider (HCP) recommendation; however, it is unclear how issues relating to race/ethnicity may mitigate these recommendations. Research shows that racial/ethnic and gender concordance between a patient and HCP can improve patient satisfaction, access and quality of care. If concordance contributes to improved patient-provider interactions, then it may be a factor in patient decisions regarding HPV vaccination. The objectives of this study were to (1) explore gender and ethnicity HCP preference regarding HPV vaccination among unvaccinated; and (2) understand factors associated with those preferences. Design: Unvaccinated Latina college students (n = 187) completed a survey that assessed HCP preferences, medical mistrust, cultural assimilation and HPV vaccine recommendation. Logistic regression models evaluated associations between above variables with HPV knowledge and preference for a female and/or Latina HCP. Results: Most respondents had health insurance (71%), a regular HCP (64%), were US-born (67%), with foreign-born parents (74%). Thirty-four percent and 18% agreed that they would be more likely to get the HPV vaccine if the recommending HCP was female and Latino, respectively. Latina women reporting higher medical mistrust preferred a HPV vaccine recommendation from a Latino/a provider. Conclusions: Latinas' preferences regarding gender and ethnicity of their HCPs may affect patient-provider interactions. Increasing diversity and cultural awareness among HCPs, and providing linguistically and culturally-appropriate information may decrease patient-provider mistrust, increase uptake of the HPV vaccine, and decrease persistent cervical cancer disparities.

Knowledge and Attitudes Toward Human Papillomavirus Vaccination Among Latina Mothers of South American and Caribbean Descent in the Eastern US

Purpose: The purpose of this study was to examine knowledge, attitudes, barriers, and facilitators for human papillomavirus (HPV) vaccination among Latina mothers of HPV vaccine-eligible children in low-income urban areas, as well as useful strategies to improve HPV vaccination. Methods: The study included 132 Latina mothers of HPV vaccine-eligible children, interviewed in 14 focus groups. Using semi-structured discussions, mothers were asked about their knowledge about HPV infection and vaccine, views toward HPV vaccination, barriers for HPV vaccine initiation as well as completion, and opinions on strategies to improve HPV vaccination. Results: Only 55% of mothers reported having ever heard of the HPV vaccine, 27% of mothers indicated initiating the HPV vaccine, and 14% indicated completing the multi-dose series. Mothers generally lacked knowledge about HPV infection and vaccination, with varying degrees by Latino descent. Health care provider (HCP) recommendation was the strongest barrier/facilitator for HPV vaccination. Useful strategies to improve HPV vaccine initiation and completion that the mothers suggested included strong recommendation from HCPs and addressing side effects and safety concerns. Other useful strategies included community and school-based approaches and the use of text messaging and smartphone technology to educate mothers and send vaccine reminders. Conclusion: The findings provide insight for the development of interventions targeting low-income Latina mothers and the need to improve HCP communication on HPV vaccination.

A randomized, controlled, pragmatic trial of an iPad-based, tailored messaging intervention to increase human papillomavirus vaccination among Latinos

Human papillomavirus (HPV) causes a number of cancers that disproportionally affect Latinos yet there is a paucity of research on interventions to increase HPV vaccination among this population. We sought to evaluate the efficacy of a web-based, individually customizable intervention, called CHICOs (Combatting HPV Infection and Cancers, tailored intervention) for its impact on HPV vaccine utilization. We conducted a three-armed, randomized, controlled trial in the waiting rooms of five family medicine practices from June 2014-February 2016 where CHICOS was compared to an iPad-based version of the Vaccine Information Sheet from the Centers for Disease Control and Prevention (untailored intervention), and usual care. Pair-wise comparisons between study arms of 6 different measures of HPV vaccine uptake were assessed, with analyses stratified by adolescents versus young adults. Of the 1,294 participants enrolled in the study, 1,013 individuals could be assessed for vaccination. Across study arms, 265 adolescents, but only 18 young adults, received an HPV vaccine dose during the study period. In both intention-to-treat and per-protocol analyses there were essentially no differences between the CHICOS and untailored arms in any vaccination measure, or between the untailored or CHICOS arms and usual care. Our study suggests that a tailored educational intervention may not be effective for increasing HPV vaccine uptake among Latino adolescents or young adults. However, the higher than expected baseline levels of positive vaccination attitudes of study participants could have diminished the statistical power of the study. Trial Registration Number: ClinicalTrials.gov (NCT02145156).

HPV Knowledge and Vaccine Initiation Among Mexican-Born Farmworkers in North Carolina

The human papilloma virus (HPV) vaccine is an effective but underused cancer prevention tool. This study assessed knowledge of HPV and HPV vaccine initiation among Mexican-born farmworkers in North Carolina. Interviewer-administered questionnaires were conducted with 100 Latino farmworkers and 100 nonfarmworker Latino North Carolina residents in 2015 as part of an ongoing community-based participatory research project. Farmworkers had low levels of knowledge about HPV and the HPV vaccine. They had a similar amount of HPV and HPV vaccine knowledge compared to nonfarmworkers. Farmworkers and nonfarmworkers learned about the HPV vaccine from different sources. Adolescent children of farmworkers and nonfarmworkers had low HPV vaccine initiation. However, for children living in the United States with farmworker parents, vaccine initiation was high. To prevent HPV-related cancers and improve health equity, interventions are needed in order to increase HPV education and vaccine initiation among children of Mexican-born farmworkers and nonfarmworkers. Public health programs should look for partners outside the traditional health care setting to reach underserved populations. Other key strategies include promoting catch-up vaccines, improving patient-provider communication, and providing case management services.

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.

Using Community Engagement to Develop a Web-Based Intervention for Latinos about the HPV Vaccine

Human papillomavirus (HPV) infection is pervasive among sexually active women and men, and Hispanic women are at particularly high risk as they have higher rates of invasive cervical cancer compared to other racial or ethnic groups in the United States. There is a need for interventions to increase HPV vaccination among this high-risk population. This study investigated how to modify a previously developed web-based intervention that provided individually tailored information about HPV to improve its use among the Latino population. A community-oriented modification approach incorporated feedback from a community advisory committee, and focus groups among the Latino population, to modify the intervention. Several themes emerged including a need for basic information about HPV and HPV vaccination, changes to make the intervention appear less clinical, and incorporation of information addressing barriers specific to the Latino community. This work was done in preparation for a randomized trial to assess the impact of this modified intervention on HPV vaccination attitudes and uptake among Latino young adults and parents of adolescents. If effective, our intervention could be a resource for reducing HPV vaccination concerns, improving immunization rates, and educating Latinos about HPV and the HPV vaccine outside of the time boundaries of the traditional clinical encounter.

Determinants of HPV vaccine awareness and healthcare providers' discussion of HPV vaccine among females

Two human papillomavirus (HPV) vaccines are available and can prevent 98% of HPV 16 and 18 infections. This study aimed to explore determinants of 1) HPV vaccine awareness among a cohort of low-income women participating in a cancer prevention program in Central Texas and compare them to United States residents; 2) determinants of healthcare providers' discussion of HPV vaccine among female residents of the United States.

Bivariate and multivariable analysis of HPV vaccine awareness using survey data (n = 359) collected between 2014 and 2016 in Central Texas, and the Health Information and Nutrition Survey (HINTS) data which is a nationally representative dataset (unweighted n = 1214) collected in 2013 were conducted. Bivariate and multivariable regression analyses of healthcare providers' discussion of the HPV vaccine using the HINTS survey data were also conducted.

Compared to non-Hispanic Whites, there was a decreased likelihood of HPV vaccine awareness among non-Hispanic Blacks (OR = 0.50; 95% CI = 0.28–0.90) and Hispanics (OR = 0.55; 95% CI = 0.30–0.99) in the grant funded program, as well as non-Hispanic Blacks (OR = 0.28; 95% CI = 0.14–0.58) and Hispanics (OR = 0.22; 95% CI = 0.12–0.41) in the HINTS data. There was also a decreased likelihood of healthcare providers discussing the HPV vaccine with respondents who were 35–49 years (OR = 0.50; 95% CI = 0.30–0.84), 50–64 years (OR = 0.26; 95% CI = 0.14–0.49) or ≥ 65 years compared to those who were 18–34 years among the HINTS data respondents.

Interventions to increase HPV awareness among non-Hispanic Blacks and Hispanics, as well as encourage healthcare providers' discussion of the HPV vaccination during patient encounters regardless of the patient's age are needed.

•

African Americans and Hispanics were less likely to be aware of the HPV vaccine.

•

Residence was not associated with HPV vaccine awareness.

•

Age was associated with healthcare providers' discussion of HPV vaccine.

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.

Understanding HPV vaccination among Latino adolescent girls in three U.S. regions

A multi-site study was conducted to assess HPV vaccine initiation and correlates of initiation among Latina adolescents. The study was a collaboration of the CDC/NCI-funded Cancer Prevention and Control Research Network. Data were collected in 2009 from caregivers of Latina adolescents recruited from Los Angeles Country (n = 274), Washington State (Yakima Valley region; n = 90), and Texas (Houston, n = 38; Lower Rio Grande Valley, n = 42). A set of 24 survey items assessed use of the HPV vaccine and awareness, attitudes and barriers to vaccination. Moderate levels of vaccine awareness among caregivers and low uptake of the vaccine (26-37%) among girls were observed. Attitudinal barriers such as concerns about negative effects of the vaccine on daughter's sexual behavior, fertility, and future health were infrequently endorsed. Efforts to understand regional similarities and differences may help inform interventions.

Factors Influencing Mexican Women's Decisions to Vaccinate Daughters Against HPV in the United States and Mexico

Mexican and Mexican-American women bear high cervical cancer burdens, yet relationships between mothers' experiences of vaccinating daughters against cervical cancer-causing human papillomavirus (HPV) on both sides of the border are unknown. We surveyed 400 Mexican-born women in Oxnard, California, United States and Cuernavaca, Morelos, Mexico, about their beliefs and practices regarding daughters' HPV vaccination, conducting in-depth interviews with 35 participants. Contextualizing interview findings in survey data, we identify key factors influencing mothers' experiences regarding daughters' HPV vaccination in both countries. Although US acculturation influenced some participants' concerns, US and Mexico participants overwhelmingly desired eventual vaccination; structural rather than cultural barriers limited vaccine uptake.

Evaluation of fotonovela to increase human papillomavirus vaccine knowledge, attitudes, and intentions in a low-income Hispanic community

BACKGROUND

It has nearly been a decade since the introduction of the vaccine against human papillomavirus (HPV), yet vaccination rates in the United States have remained suboptimal, particularly among Hispanics. Culturally and linguistically relevant health education tools targeting Hispanics are needed to increase the current rate of HPV vaccination. This article evaluates a theory-informed, evidence-guided fotonovela (photographic short story) intervention to improve HPV vaccination knowledge, attitudes, and intention among young adults.

METHODS

Young adults (N = 41, aged 18-26 years) in a low-income primary care clinic in Southern California were administered pre- and post-intervention surveys to measure changes in perceived susceptibility to HPV, perceived benefit of vaccination in committed relationship, intention to vaccinate, intention to encourage social networks to vaccinate, and attitude towards vaccination. Post-intervention survey also examined attitudes towards fotonovela. Relationships between attitudes towards fotonovela and demographic characteristics were assessed with Fisher's exact test. Self-reported gains in knowledge were categorized and tabulated. Changes in perceptions and intentions were analyzed with the marginal homogeneity test.

RESULTS

The majority of participants were female (78.0%), Latino/Hispanic (92.7%), single (70.7%), and had at least a college education (61.0%). The mean age was 21.9 years (SD 0.4). The fotonovela was viewed as entertaining (95.1%), educational (97.6%), and easy to read (100 %). Following the intervention, Hispanic participants improved in all five variables of interest measured in the survey, including perceived susceptibility (+10.5%, p = 0.03), benefit of vaccination (+7.8%, p = 0.25), intent to vaccinate (+18.4%, p = 0.06), intent to encourage others to vaccinate (+10.5%, p = 0.14) and attitude towards vaccination (+13.1%, p = 0.05). Improvements in perceived susceptibility and attitude towards vaccination reached statistical significance (p < 0.05). The most frequent gains in knowledge were the risk of HPV infection despite condom use (N = 16) and relationship status (N = 8), three-dose vaccine administration schedule (N = 13), and burden of HPV infection among males (N = 9).

CONCLUSION

Results are promising because they demonstrate that health messages delivered through a narrative format can promote positive changes in knowledge, attitudes, and intentions. The fotonovela may be a powerful vehicle for HPV education, particularly among Hispanics.

Cultural influences on HIV testing among Latino youth

Young Latinos aged 13-24 years in the USA are disproportionately impacted upon by HIV. Despite the elevated risk, lower rates of HIV testing have been documented among Latino youth relative to other racial/ethnic groups. The objective of the current study was to examine the influence of acculturation and cultural values on HIV testing among Latino youth. The study consisted of 51 sexually experienced young Latinos aged 13-16 years from a major city in the Southeastern USA. Participants completed a survey on HIV testing history, cultural orientation and Latino cultural values. Results indicate that 21.6% of the young people had been tested for HIV. The number of times tested ranged from one to four (M = 1.9 ± 1.0). HIV testing was associated with US American cultural orientation and familism (and emphasis on strong family commitment, family support and emotional closeness). Participants with greater orientation to US American culture were more likely, whereas those who endorsed higher familism value were less likely, to have had an HIV test. For participants scoring high on familism, the desire to maintain family honour may serve as a deterrent to testing. Incorporating culturally relevant strategies, such as promoting sexual communication and conversations on HIV prevention within the family, may enhance testing and narrow the gap in HIV infection between Latino youth and other ethnic groups.

Increasing Cervical Cancer Screening Among US Hispanics/Latinas: A Qualitative Systematic Review

Hispanic/Latina women experience the highest cervical cancer incidence rates of any racial/ethnic group in the USA and tend to present with more severe cases and experience higher mortality compared to most other populations. The goals of this qualitative systematic review were to explore existing interventions to increase cervical cancer screening among US Hispanics/Latinas and to identify characteristics of effective interventions and research gaps. Six online databases were searched from their inception through June 30, 2013, using designated search terms and keywords. Peer-reviewed articles that documented an intervention designed to improve screening for cervical cancer among Hispanics/Latinas ages 18 years and older living in the USA were reviewed. Data were abstracted using a standardized form to document intervention characteristics and results. Forty-five articles, describing 32 unique interventions, met inclusion criteria. Identified interventions consisted primarily of educational programs and/or provision of screening. Interventions used lay health advisors (LHAs), clinic-based outreach/delivery strategies, partnerships with churches, and mass media campaigns. Twelve interventions resulted in significant increases in cervical cancer screening rates. Interventions developed utilizing theory, applying community-based participatory research approaches, and using LHAs were identified as having the greatest potential for improving cervical cancer screening among Hispanics/Latinas. There continues to be a need for the development of interventions in geographic areas with new and emerging Hispanic/Latino populations and that are comprehensive, follow participants for longer periods of time, and broaden the roles and build the capacities of LHAs.

Mothers' acceptance of human papillomavirus (HPV) vaccination for daughters in a country with a high prevalence of HPV

Cervical cancer is the second most common cancer among women in Argentina and the mortality rate is not declining despite opportunistic screening. Free-of-charge human papillomavirus (HPV) vaccination of 11-year-old girls was introduced in 2011. Parental acceptance of HPV vaccination is considered to be of great importance for HPV vaccine uptake. However, little is known regarding this factor in Argentina. The aim of the present study was to explore maternal HPV vaccination acceptance, willingness to pay for HPV vaccination and correlates of this willingness, awareness of HPV and HPV-associated disease and behaviors and attitudes associated with HPV vaccination acceptance. A total of 180 mothers of girls aged 9-15 years comprised this quantitative, cross-sectional, survey-based study, conducted at two hospitals in the Mendoza Province. Correlates of willingness to pay for HPV vaccination were obtained using multivariable logistic regression models. Maternal HPV vaccination acceptance was 90%, and 60% of mothers were willing to pay for HPV vaccination. Mothers who were gainfully employed and had a higher disposable household income were significantly more willing to pay for HPV vaccination [odds ratio (OR)=2.54, 95% confidence interval (CI) 1.01-6.38; OR=3.28, 95% CI 1.36-7.94, respectively], as were mothers who were aware of cervical cancer prior to the study (OR=3.22, 95% CI 1.02-10.14). Only one in 10 mothers were informed that HPV vaccination does not offer complete protection against cervical cancer. In conclusion, the present study showed high maternal HPV vaccination acceptance, although acceptance decreased when vaccination was not free-of-charge. Continuous public education campaigns are needed to improve knowledge of HPV, HPV vaccines and HPV-associated disease.

[Acceptability of human papillomavirus vaccine in mothers from Valencia (Spain)]

INTRODUCTION

In October 2008, Valencian Community started its human papillomavirus (HPV) vaccination schedules for 14 year-old girls. The aim of this study is to assess knowledge about HPV infection and its vaccine among the mothers of these girls, and to identify factors associated with the willingness to vaccinate their daughters.

MATERIAL AND METHODS

Cross-sectional study by means of a questionnaire to mothers of girls born in 1995, and attending secondary schools in the province of Valencia during 2010-2011. Cluster stratified random sample (n=1279).

STATISTICAL ANALYSIS

percentages, confidence intervals, OR, Chi-squared and multivariate logistic regression contrasts.

RESULTS

A total of 833 (65.1%) questionnaires were completed. The results obtained showed that, 76.6% of mothers had vaccinated their daughters against HPV; 93.8% knew about the vaccine, particularly through television (71.5%); and 78.5% received positive advice from a health professional which increased the vaccination of their daughters (OR: 2.4). There was low overall knowledge about HPV infection and vaccination. Confidence of the mothers in vaccines as a preventative method increases the HPV vaccination (OR: 3.8). The first reason for refusal was the fear of adverse events (45.6%).

CONCLUSIONS

Apparently, the media does not influence the willingness to vaccinate. It would be desirable to minimize the perception of risk of the vaccine. Positive health advice from a health professional can have a positive effect on vaccination. There is a gap between the level of knowledge and decision-making to vaccinate.

Acceptability of human papilloma virus vaccination among women in the United Arab Emirates

BACKGROUND

Human papilloma virus (HPV) is a common sexually transmitted infectious agent. It is estimated that 10% of all women worldwide are infected with HPV, that is some 660 million each year. HPV vaccination has a reported efficacy of more than 98% for protection against infection in females. In 2008 the Abu Dhabi Health Authority in the United Arab Emirates (UAE) introduced free HPV vaccination for all eligible schoolgirls in both public and private schools.

METHODS

A cross-sectional study of 640 women aged 18-50 years in the Emirate of Abu Dhabi in UAE from April 2012 to October 2012 was conducted.

RESULTS

Thirty-seven percent of the women in our sample had heard about HPV vaccination, and 80% of these would consider getting vaccinated themselves, and 87% would recommend vaccination to relatives or friends. Most women in the study (69%) had a favorable opinion about the vaccine. Only 17% of the women felt it might not be culturally acceptable, and 1% felt that there might be religious objections to HPV vaccination. Vaccine safety and recommendation by a doctor (36% each) were the factors identified most frequently by our sample of women which would enhance the uptake of the HPV vaccination.

CONCLUSIONS

Knowledge about HPV vaccination among women in our sample was below average (37%); however, 80% of those who had heard about HPV vaccination were willing to be vaccinated themselves, and 87% would recommend vaccination to relatives and friends.

Perception of human papillomavirus infection, cervical cancer and HPV vaccination in North Indian population

BACKGROUND

Human Papillomavirus (HPV) -associated cervical cancer is the second-most common cancer in women worldwide but it is the most frequent gynaecological cancer and cancer associated death in India women. The objective of this study was to assess knowledge about cervical cancer, HPV, HPV vaccine, HPV vaccine acceptance among school and undergraduates students and their parent's perception about acceptance of HPV vaccine in Northern part of India (Delhi and NCR regions).

MATERIALS AND METHODS

A qualitative questionnaire based survey among 2500 urban/rural students aged 12-22 years was conducted.

RESULTS

Overall, a low frequency (15%) of HPV and cervical cancer awareness was observed in students and their parents. However, the awareness was much higher in females belonging to urban setup compared to boys with a perception that HPV causes cervical cancer in women only. Additionally, only (13%) participants who were aware of cervical cancer and HPV) were willing to accept HPV vaccination. Apparently, parents of female students were two times more willing to accept HPV vaccination for their ward than male students (p<0.001; OR 95%CI = 2.09 (1.58-2.76).

CONCLUSION

Cervical cancer and HPV awareness among school, undergraduate students and also to their parents was found to be very low in this part of India. The level of awareness and education appears to be insignificant determinants in rural compared to urban setup. Better health education will be needed to maximize public awareness for cervical cancer prevention.

Race, ethnicity, and income factors impacting human papillomavirus vaccination rates

BACKGROUND

Human papillomavirus (HPV) infection and cervical cancer disproportionately affect low-income and minority women. HPV vaccines have the potential to either reduce or exacerbate racial disparities in HPV-related diseases and cervical cancers, depending on the equitability of vaccine uptake.

OBJECTIVES

This review aims to identify barriers and facilitators of equitable uptake of HPV vaccination among low-income and minority girls. This review discusses factors related to race, ethnicity, and income that are associated with initiation and completion rates of the 3-dose HPV vaccine series and presents targets for intervention.

METHODS

We reviewed relevant English-language literature to identify current vaccination rates and factors associated with vaccine uptake. Study findings related to race (black, Latino, Asian), and incomes were summarized.

RESULTS

Current trends in the United States indicate low uptake among all adolescents, and that rates stagnated between 2011 and 2012. Low-income and minority adolescents are equally or more likely to start the HPV vaccination series than are white and higher-income adolescents, but are less likely to complete all 3 shots. Provider recommendation is a key factor in HPV vaccination, and minorities are less likely to report receiving recommendations for HPV vaccination.

CONCLUSIONS

As black, Hispanic, and Asian populations continue to grow in the United States over the next several decades, it is imperative that we not only improve HPV vaccination rates overall, but also focus on high-risk populations to prevent an increase in cervical cancer disparities.

Barriers and facilitators to HPV vaccination of young women in high-income countries: a qualitative systematic review and evidence synthesis

BACKGROUND

Vaccination against Human Papillomavirus (HPV) is recommended for adolescent young women prior to sexual debut to reduce cervical cancer related mortality and morbidity. Understanding factors affecting decision-making of HPV vaccination of young women is important so that effective interventions can be developed which address barriers to uptake in population groups less likely to receive the HPV vaccine.

METHODS

We undertook a qualitative systematic review and evidence synthesis to examine decision-making relating to the HPV vaccination of young women in high-income countries. A comprehensive search of databases from inception to March 2012 was undertaken to identify eligible studies reporting the perspectives of key stakeholders including policy makers, professionals involved in programme, parents, and young women. Factors affecting uptake of the vaccine were examined at different levels of the socio-ecological model (policy, community, organisational, interpersonal and intrapersonal).

RESULTS

Forty-one studies were included. Whether young women receive the HPV vaccine is strongly governed by the decisions of policy makers, healthcare professionals, and parents. These decisions are shaped by: financial considerations; social norms and values relating to sexual activity, and; trust in vaccination programmes and healthcare providers. Financial constraints may be overcome through universal healthcare systems offering the HPV vaccine free at the point of delivery. In the healthcare setting, judgements by healthcare professionals about whether to recommend the vaccine may restrict a young woman's access to the vaccine irrespective of her own beliefs and preferences. Parents may decide not to allow their daughters to be vaccinated, based on cultural or religious perceptions about sexual activity.

CONCLUSIONS

Barriers to the uptake of the HPV vaccine have implications for young women's future sexual, physical and reproductive health. Interventions to address barriers to uptake of the vaccine should target appropriate, and multiple, levels of the socio-ecological model. Issues of trust require clear, accessible, and sometimes culturally appropriate, information about the HPV vaccination programme. Although young women are central to the HPV vaccination programme, their views are underrepresented in the qualitative literature. Future research should consider young women's perceptions of, and involvement in, consent and decision-making.

Provider-verified HPV vaccine coverage among a national sample of Hispanic adolescent females

BACKGROUND

Hispanic females have the highest cervical cancer incidence rate of any racial or ethnic group in the United States, yet relatively little research has examined human papillomavirus (HPV) vaccination among this fast-growing population. We examined HPV vaccination among a national sample of Hispanic adolescent females.

METHODS

We analyzed provider-verified vaccination data from the 2010-2011 National Immunization Survey-Teen for Hispanic females ages 13 to 17 years (n = 2,786). We used weighted logistic regression to identify correlates of HPV vaccine initiation (receipt of one or more doses), completion (receipt of three doses), and follow-through (receipt of three doses among those who initiated the series).

RESULTS

HPV vaccine initiation was 60.9%, completion was 36.0%, and follow-through was 59.1%. Initiation and completion were more common among older daughters and those whose parents had received a provider recommendation to vaccinate (all P < 0.05). Completion was less common among daughters who had moved from their birth state (P < 0.05). All vaccination outcomes were less common among daughters without health insurance (all P < 0.05). Vaccination did not differ by parents' preferred language (all P > 0.05), although intent to vaccinate was higher among Spanish-speaking parents (P < 0.01). Spanish-speaking parents were more likely to indicate lack of provider recommendation (20.2% vs. 5.3%) and cost (10.9% vs. 1.8%) as main reasons for not intending to vaccinate (both P < 0.05).

CONCLUSIONS

Many Hispanic females have not received HPV vaccine. Several factors, including provider recommendation and health insurance, are key correlates of vaccination.

IMPACT

HPV vaccination programs targeting Hispanics are needed and should consider how potential barriers to vaccination may differ by preferred language.

HPV vaccination: are we initiating too late?

BACKGROUND

Human papillomavirus (HPV) vaccination is recommended in early adolescence. While limited data suggest that patients frequently delay initiation of the three-dose series, age-based variability in initiation of HPV vaccination and its clinical relevance are not well described. Thus, this study aims to characterize HPV vaccination delay among adolescent and young adult females.

METHODS

This retrospective cohort study examined age at HPV vaccination initiation and missed opportunities for receipt of the first vaccine dose (HPV1) among 11-26 year-old females (n=22,900) receiving care at 16 urban academically-affiliated ambulatory care clinics between 2007 and 2011. Predictors of timely vaccination and post-licensure trends in age at HPV1 receipt were assessed using multivariable logistic regression and a generalized linear mixed model, respectively. Chlamydia trachomatis and Papanicolaou screening before HPV vaccination initiation, as markers of prior sexual experience and associated morbidity, were examined in a subcohort of subjects (n=15,049).

RESULTS

The proportion of 11-12 year-olds who initiated HPV vaccination increased over time (44.4% [2007] vs. 74.5% [2011], p<0.01). Initiation rates also improved among 13-26 year-olds. Thus, the mean age at HPV1 receipt remained unchanged between 2007 and 2011 (16.0 ± 2.7 vs. 15.9 ± 4.0 years, p=0.45). Spanish language was a positive predictor (AOR 1.62, 95% CI 1.05-2.48) of HPV vaccination initiation among 11-12 year-olds in 2011. The majority (70.8-76.4%) of unvaccinated subjects experienced missed vaccination opportunities. Of the subcohort, 36.9% underwent Chlamydia screening before HPV1 receipt (19.1% with ≥ 1 positive result). Of those with prior Papanicolaou screening (16.6%), 32.1% had ≥ 1 abnormal result.

CONCLUSIONS

These low-income, minority females frequently delayed initiation of HPV vaccination. Many had evidence of prior sexual experience and associated morbidity, placing them at risk of HPV-related complications. Promoting timely HPV vaccination and reducing missed vaccination opportunities are crucial.

Predictors of human papillomavirus vaccination among daughters of low-income Latina mothers: the role of acculturation

PURPOSE

Human papillomavirus (HPV) vaccination is a safe and effective primary prevention strategy for cervical cancer. Little is known about correlates of HPV vaccination among Hispanic adolescents living in the United States. The purpose of this study was to (1) examine relationships between both U.S./American and Latina acculturation and variables typically associated with HPV vaccine uptake (e.g., physician recommendation); and (2) identify predictors of HPV vaccine uptake among daughters of Latina mothers.

METHODS

Latina mothers (N = 200) recruited from a Federally Qualified Health Center serving low-income families in Florida completed a semistructured interview that assessed awareness of and knowledge about HPV and HPV-vaccines, vaccination beliefs, whether their daughter's physician had recommended the HPV vaccine, health history, U.S./American and Latina acculturation, mother and daughter demographics, and daughter's HPV vaccination status.

RESULTS

Only 18% of daughters had received at least one dose of the vaccine. Higher levels of U.S./American acculturation were associated with greater odds of vaccine uptake and other common predictors of HPV vaccination (e.g., physician recommendation, vaccine awareness). A multivariate logistic regression analysis identified three independent predictors of vaccine uptake: physician recommendation, daughter's age, and low worry about how to pay for the vaccine.

CONCLUSIONS

Despite generally favorable views of HPV vaccination, observed rates of vaccine uptake in this sample were substantially lower than national estimates. Latina mothers who are more integrated into U.S. society may be more likely to vaccinate their daughters against HPV. Findings provide promising directions for future HPV vaccination interventions with Hispanic adolescents.

"HPV? Never heard of it!": a systematic review of girls' and parents' information needs, views and preferences about human papillomavirus vaccination

BACKGROUND AND OBJECTIVE

Two human papillomavirus vaccines were licenced in 2006/2007 for cervical cancer prevention. National vaccination programmes for schoolgirls were subsequently introduced in some European countries, North America and Australia. To understand factors influencing vaccine uptake and to inform the development of appropriate UK educational materials, we aimed to synthesise evidence of girls' and parents' information needs, views and preferences regarding HPV vaccination.

DESIGN

Systematic review and mixed method synthesis of qualitative and survey data.

DATA SOURCES

Twelve electronic databases; bibliographies of included studies 1980 to August 2011.

REVIEW METHODS

Two reviewers independently screened papers and appraised study quality. Studies were synthesised collaboratively using framework methods for qualitative data, and survey results integrated where they supported, contrasted or added to the themes identified.

RESULTS

Twenty-eight qualitative studies and 44 surveys were included. Where vaccination was offered, uptake was high. Intention to decline was related to a preference for vaccinating later to avoid appearing to condone early sexual activity, concerns about vaccine safety and low perception of risk of HPV infection. Knowledge was poor and there were many misconceptions; participants tried to assess the potential benefits and harms of vaccination but struggled to interpret limited information about HPV in the context of existing knowledge about sexually transmitted infections and cancer. Conclusion Many girls and their parents have limited understanding to an extent that impinges on their ability to make informed choices about HPV vaccination and could impact on future uptake of cervical screening. This is a considerable challenge to those who design and provide information, but getting the messages right for this programme could help in developing patient information about other HPV related cancers.

Health care professional communication about STI vaccines with adolescents and parents

Vaccination of adolescents against sexually transmitted infections (STIs) is an important prevention strategy that may reduce the global burden of disease. The World Health Organization, Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices, and other national health agencies recommend the use of existing STI vaccines, and many countries have incorporated them into their routine vaccination schedule. Despite this, however, data indicate that STI vaccine uptake is suboptimal for a variety of reasons. Health care professionals (HCP) have been shown to have a strong beneficial effect on STI vaccine uptake, yet studies demonstrate that many HCPs fail to discuss or recommend them to adolescent patients. This review article focuses on HCP communication about STI vaccines with adolescents and their parents. It describes STI vaccine message content and delivery as well as the context in which HCPs formulate their messaging approach. It also examines other contextual factors that may shape communication about STI vaccines. Studies from many countries indicate that HCPs often possess misinformation about adolescents, including their sexual risk behaviors, as well as STIs, vaccine safety and efficacy, and STI vaccination recommendations. They also have misconceptions of parental barriers to STI vaccination. These may impact STI vaccine communication and have a negative influence on STI vaccine uptake. These findings highlight the critical need for improved HCP education related to adolescent health, sexuality, and STI vaccination. This may be particularly important in settings without an existing infrastructure or expertise in caring for this unique patient population.

Hispanic mothers' and high school girls' perceptions of cervical cancer, human papilloma virus, and the human papilloma virus vaccine

PURPOSE

Cervical cancer incidence and mortality are higher for Hispanic women than for women in other population groups. However, the incidence could be reduced if teenaged Hispanic girls received the human papillomavirus (HPV) vaccine before they become sexually active. Unfortunately, few Hispanic girls receive this vaccine, which prevents cervical cancer. This study assessed Hispanic mothers' and girls' perceptions about cervical cancer, HPV, and the HPV vaccine. Results show factors that affect whether Hispanic high school girls receive the vaccine.

METHODS

Twenty-four Hispanic mothers and 28 Hispanic girls from an urban school district in southeast Texas each participated in one of eight focus groups. Bilingual moderators facilitated the mothers' groups in English and Spanish and the girls' groups in English. We analyzed transcripts of the discussions and identified themes using the grounded theory approach.

RESULTS

Our analysis found several themes that affect whether Hispanic girls get the HPV vaccine: gaps in knowledge; fears and concerns about the vaccine; sociocultural communication practices; and decision-making about HPV vaccination. Both mothers and girls had limited knowledge about cervical cancer, HPV, and the vaccine. Some girls who received the vaccine said they wished their mothers had involved them in making the decision.

CONCLUSIONS

Findings may help in developing school or community-based educational programs for Hispanic families. Such programs should provide information on the HPV vaccine and the link between HPV and cervical cancer, and they should assist mothers and girls in communicating to make informed decisions about the vaccine.

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

OBJECTIVE

We conducted a descriptive study of the correlates of refusal and acceptance of human papillomavirus (HPV) vaccination by rural parents of preadolescent and adolescent children. We hypothesized that the correlates of parents who allow their children aged 9 to 13 years to get the HPV vaccine and those of parents who do not allow vaccination would differ significantly.

METHODS

This cross-sectional study was implemented during the school years 2009-2011 in the elementary and middle schools of three rural counties in Georgia. Parents were recruited at school functions to complete an anonymous validated survey.

RESULTS

Parents who chose to vaccinate their children or intended to vaccinate were twice as likely to be from a race other than African American and 2.7 times more likely to have a religion other than Baptist. Using stepwise logistic regression and after adjustment for race and religion, we found that parents who had vaccinated or intended to vaccinate had significantly higher scores on perceived barriers (1.02 times more likely to vaccinate) and lower scores on perceived benefits (1.01 times more likely to vaccinate) (model p < .001).

CONCLUSIONS

The results suggest that healthcare providers in rural areas can increase HPV vaccine uptake and reduce HPV-related cancers by using a multifaceted approach to educating their patients within the context of the patients' cultural values, geographic location, and economic situation. Such an approach could dispel misinformation and increase vaccine uptake.

Race, ethnicity and income as factors for HPV vaccine acceptance and use

If distributed equitably, Human Papillomavirus (HPV) vaccines have the potential to reduce racial disparities in HPV-related diseases and cervical cancers. However, current trends in the US indicate low uptake among all adolescents, with persistent disparities among minority and low-income adolescents despite largely positive views of vaccination among their parents. As Black, Hispanic, and Asian populations continue to grow in the US over the next 40 y, it is imperative that we not only improve HPV vaccination rates overall, but focus on high-risk populations to prevent an increase in cervical cancer disparities. This review discusses initiation and completion rates of the three-dose HPV vaccine series among adolescents in high-risk groups and describes cultural similarities and differences in motivation and barriers to vaccination. The goal of this review is to highlight factors leading to vaccination in different adolescent racial groups and to help guide the development of strategies to increase rates of vaccine initiation and completion among groups at the highest risk for developing cervical cancer.

The role of herd immunity in parents' decision to vaccinate children: a systematic review

BACKGROUND AND OBJECTIVE

Herd immunity is an important benefit of childhood immunization, but it is unknown if the concept of benefit to others influences parents' decisions to immunize their children. Our objective was to determine if the concept of "benefit to others" has been found in the literature to influence parents' motivation for childhood immunization.

METHODS

We systematically searched Medline through October 2010 for articles on parental/guardian decision-making regarding child immunization. Studies were included if they presented original work, elicited responses from parents/guardians of children <18 years old, and addressed vaccinating children for the benefit of others.

RESULTS

The search yielded 5876 titles; 91 articles were identified for full review. Twenty-nine studies met inclusion criteria. Seventeen studies identified benefit to others as 1 among several motivating factors for immunization by using interviews or focus groups. Nine studies included the concept of benefit to others in surveys but did not rank its relative importance. In 3 studies, the importance of benefit to others was ranked relative to other motivating factors. One to six percent of parents ranked benefit to others as their primary reason to vaccinate their children, and 37% of parents ranked benefit to others as their second most important factor in decision-making.

CONCLUSIONS

There appears to be some parental willingness to immunize children for the benefit of others, but its relative importance as a motivator is largely unknown. Further work is needed to explore this concept as a possible motivational tool for increasing childhood immunization uptake.

Provider perceptions of barriers and facilitators of HPV vaccination in a high-risk community

BACKGROUND

Maximizing HPV vaccine uptake among those at highest risk for cervical cancer is critical. We explored healthcare provider perspectives on factors influencing HPV vaccination among adolescent girls in a community with high cervical cancer rates.

METHODS

From March to May 2009, we conducted in-depth interviews with 21 medical staff providing care to adolescent girls at two clinics in Los Angeles, CA, serving a predominantly Hispanic population with high cervical cancer rates. Interviews were recorded and transcribed data were reviewed for coding and thematic content related to potential barriers and facilitators of HPV vaccination.

RESULTS

Providers and medical staff overwhelmingly focused on parental beliefs as barriers to HPV vaccination. Perceived parental misconceptions acting as barriers included the belief that adolescents do not need vaccinations and that no-cost vaccine programs like Vaccines for Children are only available for younger children. Perceived parental concerns that the vaccine will promote sexual activity were prevalent, which prompted providers to frame HPV vaccine as a "routine" vaccine. However, the medical staff felt mothers with a friend or relative supportive of HPV vaccination were more likely to request the vaccine. The staff also noted that for Hispanic parents the "preferred" source of information is peers; if the "right people" in the community were supportive of HPV vaccine, parents were more willing to vaccinate. Other barriers included lack of immunization records among immigrant parents and a difficult-to-reach, mobile clientele.

CONCLUSIONS

Providers noted a number of barriers to HPV vaccination, including some perceived parental misconceptions that could be addressed with education about the need for adolescent vaccines and available free vaccine programs. Because community support appears particularly important to Hispanic parents, the use of promotoras - peer liaisons between health organizations and the community - may increase HPV vaccine uptake in this population.

Formative research on HPV vaccine acceptability among Latina farmworkers

The purpose of this study was to identify the barriers and benefits to human papillomavirus (HPV) vaccination in a low-income, Latina farmworker population in central Florida. This study reports on formative qualitative research conducted on perceptions of benefits, barriers, costs, place, and promotion related to the HPV vaccine from surveys and interviews with a sample of 46 low-income, Latina farm workers and 19 health care workers serving this population. It was found that Latina farmworkers hold many misperceptions about the HPV vaccine and the potential links between HPV infection and cervical cancer. In addition, it was observed that HPV vaccination intention was inversely related to concerns about adolescent sexual behavior and low perceived risk of infection but might be positively influenced by belief in illness prevention and physician recommendation. These findings add to the growing research on HPV vaccine acceptability among Latina subgroups to inform intervention development, marketing materials, education, and policy.

Global challenges of implementing human papillomavirus vaccines

Human Papillomavirus vaccines are widely hailed as a sweeping pharmaceutical innovation for the universal benefit of all women. The implementation of the vaccines, however, is far from universal or equitable. Socio-economically marginalized women in emerging and developing, and many advanced economies alike, suffer a disproportionately large burden of cervical cancer. Despite the marketing of Human Papillomavirus vaccines as the solution to cervical cancer, the market authorization (licensing) of the vaccines has not translated into universal equitable access. Vaccine implementation for vulnerable girls and women faces multiple barriers that include high vaccine costs, inadequate delivery infrastructure, and lack of community engagement to generate awareness about cervical cancer and early screening tools. For Human Papillomavirus vaccines to work as a public health solution, the quality-assured delivery of cheaper vaccines must be integrated with strengthened capacity for community-based health education and screening.

Fathers' intentions to accept human papillomavirus vaccination for sons and daughters: exploratory findings from rural Honduras

OBJECTIVES

Little is known about fathers' attitudes toward human papillomavirus (HPV) vaccination in low-resource settings. We sought to determine the awareness of HPV vaccination among Honduran fathers, and to assess their intention to accept HPV vaccination for their sons and daughters.

METHODS

We conducted 100 structured interviews of fathers recruited from medical and business settings between May 2007 and June 2008. After assessing baseline knowledge, fathers received a brief explanation of HPV infection, cervical cancer, genital warts, and HPV vaccination. They were then asked whether they would accept HPV vaccination for their sons and daughters.

RESULTS

Prior to receiving information about HPV, 85% of fathers believed that cervical cancer was preventable, over two-thirds could correctly name some form of prevention, 22% of fathers had heard of HPV, and 17% had heard of HPV vaccination. After receiving HPV-related information, 100% of fathers intended to accept HPV vaccination for their sons and 94% intended to accept HPV vaccination for their daughters.

CONCLUSIONS

Few Honduran fathers were aware of HPV or HPV vaccination, but after receiving information, most would accept HPV vaccination for their sons and daughters.

Racial disparities in awareness of the human papillomavirus

BACKGROUND

Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States yet is one of the least recognized among the general public. HPV awareness may be relatively low among minority women. Because HPV awareness is associated with uptake of the HPV vaccine, it is critical to assess HPV awareness in the population and identify any racial/ethnic gaps.

METHODS

This study used nationally representative data collected by the National Survey of Family Growth between July 2007 and December 2008. A multivariable logistic regression model was used to determine the independent effect of race/ethnicity on HPV awareness while controlling for sociodemographic and clinical confounders in a sample of 4088 women. Stratified multivariable analysis was also conducted to assess the relationship between race/ethnicity and HPV awareness among women in different age groups.

RESULTS

After adjusting for confounders, Hispanic and black women overall were significantly less likely to have heard of HPV compared to white women (odds ratio [OR] 0.39, 95% confidence interval [CI] 0.29-0.54 and OR 0.39, 95% CI 0.29-0.54, respectively). Black women aged 15-18 and Hispanic women aged 19-26 had particularly low rates of HPV awareness (OR 0.17, 95% CI 0.07-0.43 and OR 0.18, 95% CI 0.11-0.30, respectively) compared to white women of the same ages.

CONCLUSIONS

Hispanic and black women have significantly lower levels of HPV awareness than white women. Targeted educational efforts will be important to improve HPV awareness and associated preventive health measures to avoid HPV-related morbidity and mortality.

Implementing HPV Vaccines: Public Knowledge, Attitudes, and the Need for Education

This article reviews qualitative research on public knowledge and attitudes to HPV vaccines, focusing on socio-economically challenged populations. Keyword searches were conducted on MEDLINE and ISI Web of Science for relevant peer-reviewed literature in English. A high acceptance of HPV vaccines was found despite low knowledge about HPV (types, prevalence, transmission, health risks, and cervical screening). Facilitators of HPV vaccine uptake included fear of cancer and desire to protect children's health. Barriers included low knowledge levels, perception of HPV vaccines as potential causes of sexual disinhibition, concerns about vaccine costs, social stigma, adverse effects, and parental unwillingness to permit vaccination of pre-adolescent children. Despite acceptance of HPV vaccines, implementation in low-resource settings faces social and economic difficulties. To pursue and strengthen cervical screening in these settings, public education about HPV is key.

Patient-provider communication and human papillomavirus vaccine acceptance

The authors performed telephone interviews of parents of adolescents (n = 430) and their older adolescents (n = 208) in Monroe County, New York to measure parent and adolescent acceptance of human papillomavirus (HPV) vaccine, its association with ratings of provider communication, and vaccine-related topics discussed with the adolescent's provider. More than half of adolescent girls had already received an HPV vaccination, with fewer than one quarter refusing. Parent and teen ratings of provider communication was high, and not related to HPV vaccine refusal. Parents were more likely to refuse if they were Hispanic (odds ratio [OR] = 5.88, P = .05) or did not consider vaccines "very safe" (OR = 2.76, P = .04). Most parents of boys (85%) believed males should be given HPV vaccine if recommended. Few parents and teens recalled discussing that vaccination does not preclude future Pap smear testing. Providers should address cultural and vaccine safety concerns in discussions about HPV vaccine.

HPV AWARENESS AMONG LATINA IMMIGRANTS AND ANGLO AMERICAN WOMEN IN THE SOUTHERN U.S.: CULTURAL MODELS OF CERVICAL CANCER RISK FACTORS AND BELIEFS

Latinas have higher cervical cancer age-adjusted incidence and mortality rates, and present with more advanced disease compared to non-Latino whites. This study used a cross-sectional mixed methods survey design, exploring knowledge, attitudes, and beliefs regarding the human papillomavirus (HPV), the HPV vaccine, and cervical cancer screening with four groups of women (Mexican, Honduran, Puerto-Rican, Anglo American; n=80) attending low-income health clinics along with one group of Latina health care workers (n=17). Data analyses included univariate frequency distributions and one-way ANOVA tests for quantitative data, thematic and content analysis of qualitative data, and cultural consensus analysis using the covariance method to compare groups. Results indicate overall cultural consensus for the five subgroups for both the agree/disagree questions and rankings on cervical cancer risk factors. However, differences were found between Latina women compared to Anglo American patients and health care clinic workers around birth control practices as possible causal factors for cervical cancer. Other findings suggested greater awareness of HPV and the HPV vaccine among Anglo American and Puerto Rican women compared to Mexican and Honduran women. Mexican and Honduran women were less likely to be aware of HPV and the HPV vaccine, and more likely to be uninsured and without a regular health care provider. Results point to the need to assess knowledge, attitudes, and beliefs in specific subgroups experiencing cervical cancer disparities to identify target areas for health education. Study findings will be used to inform the development and pilot testing of health education curriculum modules for cervical cancer prevention.

Maternal support for human papillomavirus vaccination in Honduras

BACKGROUND

Cervical cancer is a leading cause of cancer death for women in Latin America, and vaccinating against human papillomavirus (HPV) has the potential to limit this disease. We sought to determine Honduran women's awareness of HPV vaccination and interest in vaccinating their daughters against HPV.

METHODS

We interviewed mothers aged ≥17 at primary care clinics in Honduras. First, we collected demographic information and assessed knowledge related to cervical cancer prevention and awareness of HPV and HPV vaccination. Because most participants were not familiar with HPV, education about the relationships among HPV, sexual activity, and cervical cancer was provided before we asked participants if they would accept HPV vaccination for a 9-year-old daughter. We used multivariable logistic regression to determine predictors of vaccine acceptance.

RESULTS

We interviewed 632 mothers. Only 13% had heard of HPV vaccination before the interview. After education, 91% would accept HPV vaccination for a 9-year-old daughter. Mothers who intended to vaccinate knew more at baseline about cervical cancer prevention than did those who did not endorse vaccination. Demographic characteristics did not predict vaccine acceptance.

CONCLUSIONS

Few Honduran mothers were aware of HPV or HPV vaccination. However, most Honduran mothers would accept HPV vaccination for their daughters after receiving education about the relationship between HPV infection and cervical cancer. Baseline cervical cancer knowledge was associated with vaccine acceptance.
