Vaccination interest and trends in human papillomavirus vaccine uptake in young adult women aged 18 to 26 years in the United States: an analysis using the 2008-2012 National Health Interview Survey

Pilot Randomized Controlled Trial of an Intervention to Promote HPV Uptake Among Young Women Who Attend Subsidized Clinics

OBJECTIVE

To evaluate the preliminary efficacy, acceptability, and feasibility of Step Up to Prevention, a technology-enhanced intervention to promote human papillomavirus (HPV) vaccination uptake among young minority and low-income women.

DESIGN

A pilot randomized controlled trial.

SETTING

Two federally supported outpatient clinics in a large city in the northeastern United States.

PARTICIPANTS

Women who were 18 to 26 years of age (N = 60).

METHODS

We randomized participants into four groups: computer information, in-person tailored, combined, and usual care. We administered computer-assisted self-interview surveys before the intervention (baseline), immediately after the intervention (postintervention), and after their clinic visit (post-clinic visit). We conducted a descriptive analysis of participant characteristics. For preliminary efficacy, we used logistic regression-assessed HPV vaccine initiation uptake rates, and we used descriptive statistics to compare theoretical mediators. We used conventional content analysis to assess participant feedback about intervention acceptability. We assessed feasibility through recruitment and retention rates and our ability to deliver the intervention.

RESULTS

We observed significant differences in initial HPV vaccine uptake between the intervention groups and the usual care group. Participant feedback indicated that the intervention was acceptable, empowering, and informative. We met our recruitment target, maintained a high retention rate (98%), and delivered the complete intervention to all participants.

CONCLUSION

We report the preliminary efficacy, acceptability, and feasibility of this intervention to promote HPV vaccine initiation among young women in federally subsided health care settings by advancing favorable views and improving knowledge about HPV vaccination.

HPV vaccination uptake among foreign-born Blacks in the US: insights from the National Health Interview Survey 2013-2017

INTRODUCTION

Human papillomavirus (HPV) vaccination uptake is lower among foreign-born than US-born individuals, but HPV-related (e.g., cervical) cancer risks are disproportionately higher among immigrant populations. Although timely vaccination can help reduce these risks, less is known about differences in the low HPV vaccination uptake among foreign-born groups, especially Black immigrants. The purpose of this study was to examine the differences in HPV vaccination initiation among US- and foreign-born Black men and women.

METHOD

Data from the 2013-2017 National Health Interview Survey on Black adults, aged 18-37 years, were analyzed in 2019. HPV vaccination initiation prevalence among US- and foreign-born blacks by region of birth were examined. Multivariate binary logistic regression analysis was used to examine the relationship between foreign-birth status and HPV vaccination initiation separately among men and women, after adjusting for sociodemographic and health-related factors.

RESULTS

There were significant differences (p < 0.001) in HPV vaccination initiation among Blacks from the US (22.5%), Africa (14.2%), and Americas/Caribbean Islands (11.4%). Adjusted odds of HPV vaccination initiation were lower among foreign- than US-born Blacks (AOR 0.71, CI 0.52, 0.98) but insignificant after controlling for health-related factors. Being ≤ 17 years versus 18-26 years at age of vaccine eligibility (AOR 3.44, CI 2.90, 4.07) was associated with HPV vaccination, and this relationship remained significant among men and women. Being single was associated with vaccination initiation among men, and some college experience, fair/poor health, obstetric/gynecological visit, and pap test were associated with HPV vaccination. Conclusion Cancer prevention strategies to promote HPV vaccination should consider making age-appropriate, gender-specific, and culturally relevant programs among foreign-born blacks in the US. Health insurance is also a key factor that might help with the lower rates of vaccinated black immigrants.

Stigma and cervical cancer prevention: A scoping review of the U.S. literature

Cervical cancer is preventable through HPV vaccination and screening however, uptake falls below national targets. A scoping review was conducted to describe stigmas related to HPV infection and vaccination and cervical cancer and screening in the US. Results were organized into the domains proposed by Stangl and colleagues' Health Stigma and Discrimination Framework. Common drivers of stigma were fear of social judgement and rejection, self-blame, and shame. Positive facilitators included social norms that provided motivation to receive HPV vaccination and screening. Gender and social norms were notable negative facilitators of stigma. HPV infection and cervical cancer resulted in stigma marking through the belief that both result from incautious behavior-either multiple sexual partners or failing to get screening. Stereotyping and prejudice were stigma practices attributed to HPV infection and cervical cancer through these same behaviors. Stigma experiences related to HPV infection, cervical cancer, and abnormal screening results included altered self-image based on perceived/anticipated stigma, as well as discrimination. This review advances understanding of the multiple dimensions of stigma associated with these outcomes in the US population. Three areas warrant additional consideration. Future studies should 1) assess how stigma dimensions affect uptake of cervical cancer preventions efforts; 2) focus on US women most affected by cervical cancer incidence and mortality to identify potential differences in these dimensions and tailor interventions accordingly; 3) include women from geographic areas of the US with high rates of cervical cancer to adapt interventions that address potential regional variations in resources and need.

Monogamy as a Barrier to Human Papillomavirus Catch-Up Vaccination

Background: Human papillomavirus (HPV) is the most prevalent sexually transmitted infection (STI) in the United States. Although a vaccine to prevent HPV infection exists, only 53.7% of females 13-17 years of age were up-to-date on the HPV vaccination series in 2018. There is a catch-up period of vaccination for females 18-26 years of age that shows consistent underparticipation. A potential barrier to vaccination is relationship status, as long-term relationships may negatively impact HPV risk perception. This study examined monogamy as a risk factor for nonvaccination and explored how risk perception may influence this association. Materials and Methods: An electronic survey was distributed to females 18-26 years of age who attended a large public university in the mid-Atlantic region (n = 629). Multivariable and descriptive statistics were estimated using SAS 9.4 to explore the likelihood of vaccination during the catch-up period by relationship status. Results: Most participants had received the HPV vaccine, a small proportion of whom received it during the catch-up period. After adjusting for confounders, women who were in monogamous relationships were significantly less likely to have participated in HPV catch-up vaccination compared to women who were single and dating (adjusted odds ratio: 0.36, 95% confidence interval: 0.15, 0.87). Women in monogamous relationships had a lower average sexually transmitted disease (STD) risk perception compared to women who were single and dating (p < 0.0001). Conclusions: A decreased risk perception may present a barrier to participating in catch-up vaccination for monogamous women. Practitioners and the public health community should focus on communicating HPV risk to women in monogamous relationships, especially given the recently expanded age range for HPV vaccination.

Acceptability of vaccination against human papillomavirus among women aged 20 to 45 in rural Hunan Province, China: A cross-sectional study

OBJECTIVE

This study aimed to examine the intentions of and barriers to vaccination against human papillomavirus (HPV) among women aged 20 to 45 in rural areas, and to determine the popular sources to getting information about HPV vaccine and vaccination.

METHODS

This cross-sectional study was conducted in 2018 with a sample of women aged 20 to 45 from rural areas of Hunan Province in China. Anonymous self-administered questionnaires were used to collect sociodemographic information and characteristics related to reproductive health of participants, and intentions of and barriers to HPV vaccination. All statistical analysis methods were performed with SPSS 18.0.

RESULTS

A total of 2101 women participated in the study, with 58.55% intended to vaccinate against HPV. Increased intention of HPV vaccination was associated with higher age (adjusted odds ratio [AOR] = 1.35 and 1.50, respectively) and education level (AOR = 1.13 and 1.47, respectively). Women who have heard of HPV vaccine (AOR = 2.67, 95% confidence interval [CI]: 1.20-5.98) and have been aware of that cervical cancer could be prevented (AOR = 2.01, 95%CI: 1.44-2.82) were more willing to vaccinate. Having never heard of HPV vaccine and worry about efficacy and safety of vaccines were the most commonly cited reasons to refuse vaccination. The preferred source to get the knowledge was medical personnel (58.45%), followed by WeChat or Microblog, TV programs, and Internet.

CONCLUSION

We found the intention of HPV vaccination among women aged 20 to 45 in rural China is low. Findings highlighted the importance of knowledge and trust in HPV vaccine, and suggested strengthening educational interventions on HPV vaccine and vaccination through multiple sources, including HPV vaccine coverage in health insurance to increase access.

Human Papillomavirus Vaccination Initiation and Completion among Youth Experiencing Homelessness in Seven U.S. Cities

Little is known about human papillomavirus (HPV) vaccination uptake among youth experiencing homelessness (YEH), who may be at higher risk for HPV than their housed counterparts. We examined the prevalence and associations of HPV vaccination initiation and completion among YEH. Guided by the Behavioral Model for Vulnerable Populations, we analyzed cross-sectional data collected from YEH (N = 1074; ages 18-26) in seven U.S. cities to assess HPV vaccination prevalence and to identify predisposing, enabling, and need factors associated with HPV vaccination status. Due to timing differences in the release of HPV vaccine recommendations, we conducted separate logistic regression analyses for men (n = 673) and women (n = 401). Approximately 19% of men and 37% of women had initiated and completed HPV vaccination. Several factors among men (i.e., older age, Latinx ethnicity, San Jose or St. Louis residence compared with New York City, never having had sex, and not previously being tested for STIs) and women (i.e., lower education level, San Jose or Houston residence compared with New York City, and never having had sex) were associated with lower odds of HPV vaccination initiation, completion, or both. Gay men had higher odds of initiating and completing the vaccination series than their heterosexual counterparts. Our findings reveal that HPV vaccination uptake is low among YEH and that there are vaccination disparities among subgroups of YEH. HPV vaccination strategies and resources that are easy-to-understand, facilitate point-of-care services, and address societal and system-level vaccination barriers encountered by YEH are needed.

Social Determinants of Health and Human Papillomavirus Vaccination Among Young Adults, National Health Interview Survey 2016

Human papillomavirus (HPV) vaccination has the potential to reduce the burden of anogenital cancers. Vaccine uptake remains suboptimal, especially among young adults. Social determinants of health (SDOH) are societal level conditions that may indirectly influence health behaviors, including HPV vaccination. The purpose of this study was to assess HPV vaccination and SDOH among young adult women and men. The 2016 National Health Interview Survey was restricted to participants ages 18-26 (n = 3593). The Healthy People 2020 SDOH Framework was used to identify variables for economic stability, health and healthcare, education, social and community context, and neighborhood and built environment. Survey-weighted logistic regression models identified SDOH variables significantly associated with HPV vaccination. Reported HPV vaccination occurred for 45.7% of women and 14.5% of men in the sample. Among women, education determinants-highest level of education completed and English language-were significantly associated with HPV vaccination. Men (adjusted OR 0.65, 95% CI 0.54, 0.79) and women (adjusted OR 0.66, 95% CI 0.49, 0.90) who did not use the Internet to look up health information were at lower odds to be vaccinated for HPV. These findings can inform future HPV vaccine uptake efforts by focusing specifically on these SDOH areas-education and health and healthcare. Identifying SDOH leverage points is critical to promoting HPV vaccination and ultimately reducing HPV-associated cancers.

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.

Human papillomavirus risk perceptions and relationship status: a barrier to HPV vaccination?

The purpose of this study was to assess the association between relationship status and perceived risk for human papillomavirus (HPV) among young adults. College adults, aged 18-26 years, completed an online survey from November 2016-April 2017 (n = 385). The survey assessed HPV vaccination status, perceived HPV risk, and current relationship status. Logistic regression models estimated the odds of perceived high risk for HPV, stratified by vaccination status. Among unvaccinated women, relationship status and HPV risk perception were significantly associated, with dating women more likely (OR = 5.33, 95%CI 1.16-24.50) to perceive a high risk for HPV compared to women in a committed relationship. Women in relationships were less likely to perceive themselves at high risk for HPV, even though HPV infection is prevalent among young adults. This association is not present for vaccinated women, suggesting that relationship status and risk perceptions may represent barriers to HPV vaccine uptake.

Outreach and Reminders to Improve Human Papillomavirus Vaccination in an Integrated Primary Care System

This study evaluated the impact of health system-based outreach and reminders on human papillomavirus (HPV) vaccine series initiation and completion. Parents of 10 to 12 year olds (n = 1805) were randomized to receive either (1) an outreach letter and brochure recommending HPV vaccination followed by automated HPV vaccine reminders or (2) usual care. We interviewed a subset of 50 parents to assess program acceptability. Outcomes were HPV vaccine initiation during the study period and on-time series completion. Rates of HPV vaccine initiation during the study period (July 2015 to August 2016) were similar between the intervention and control groups, but initiation within 120 days of randomization was higher in the intervention group (23.6% and 18.8%, P = .04) as was completion during the study period (10.3% vs 6.8%, P = .04). Reminders for doses 2 and 3 did not affect completion. The program was acceptable to parents. This study provides evidence that health system-based outreach and reminders can improve HPV vaccination.

Changes in HPV Knowledge Among College Women from 2008 to 2015

The human papillomavirus (HPV) can cause anogenital cancers and genital warts; however, it can be prevented through the HPV vaccine, which has been available since 2006. While this vaccine is targeted toward 11-to-12-year-olds, 18-to-26-year-old young adult women are eligible for "catch-up" vaccination. Knowledge of HPV may impact HPV vaccine uptake among this population. The purpose of this study was to assess changes in HPV knowledge and HPV vaccine information sources among young adult college women over a 7-year period. Two independent samples (N = 223 for 2008; N = 323 for 2015) completed a 23-item knowledge scale and survey regarding HPV. Adjusted logistic regression models compared the odds of correctly answering each knowledge item between each time period. The study found that HPV knowledge increased significantly over time (p < 0.01). The participants in 2015 were more likely than the 2008 participants to accurately report that a condom can decrease the chance of HPV transmission; there is a vaccine for women that prevents certain types of HPV; HPV can cause genital warts; HPV can be passed to a newborn at birth; and even if you do not see a wart, you can transmit HPV. Recent participants were also more likely to correctly report only women can get HPV as false. While improvements in HPV knowledge were found over time, misperceptions regarding outcomes associated with HPV persist. In order to promote HPV vaccination among this population, health literacy skills, in addition to knowledge, should be improved.

HPV Vaccination Among Foreign-Born Women: Examining the National Health Interview Survey 2013-2015

INTRODUCTION

Human papillomavirus vaccination is less prevalent among foreign-born than U.S.-born women and may lead to disparities in human papillomavirus-related cancers in the future. There is limited research on factors associated with vaccination uptake between these two groups. This study examined the association between place of birth and human papillomavirus vaccine uptake, and what determinants of vaccination attenuate this relationship.

METHODS

The 2013-2015 National Health Interview Survey data on women was analyzed in 2016, to determine differences in prevalence of human papillomavirus vaccination between foreign- and U.S.-born women. Multivariate binary logistic regression analysis was used to examine the association between foreign-born status and human papillomavirus vaccine initiation, after controlling for health insurance status, having a usual source of care, obstetrician/gynecologist visits, Pap tests, length of U.S. residency, and citizenship.

RESULTS

Human papillomavirus vaccination prevalence varied significantly among women born in different regions of the world. European and South-American women had the highest vaccination rates among all foreign-born women. Compared with U.S.-born women, foreign-born women were significantly less likely to report human papillomavirus vaccine initiation. This relationship was partially attenuated after adjusting for the covariates. Among foreign-born women, Asians were significantly less likely to report human papillomavirus vaccination uptake than white women. Additionally, living in the U.S. for >5 years was significantly associated with vaccine initiation, but attenuated by U.S. citizenship status.

CONCLUSIONS

Public health interventions to improve human papillomavirus vaccination need to be developed to address multicultural audiences with limited access to health insurance and health care.

"My mom said it wasn't important": A case for catch-up human papillomavirus vaccination among young adult women in the United States

The human papillomavirus (HPV) vaccine prevents HPV-related diseases, including anogenital cancers and genital warts. In the United States, while it is recommended to adolescents ages 11 to 12, catch-up vaccination is available for those previously unvaccinated until age 26. Parental decisions or lack of provider recommendation during adolescence are barriers to on-time vaccination. Young adult women, ages 18 to 26, are a key catch-up vaccination population as this is a period for autonomous decision-making, high healthcare utilization, and other recommended prevention behaviors. Additional intervention research is required to promote HPV vaccine uptake among young adult women. Evidence-based and theory-informed interventions need to be developed and evaluated to reach a large number of women. In order to improve HPV vaccination among young adult women, future research should integrate the themes of health literacy, alternative healthcare settings, and OB/GYN providers to facilitate improved access and shared decision-making for the vaccine. This last chance for HPV-related cancer prevention should not be forgotten in public health efforts.

Does Self-Efficacy Mediate the Relationships Between Social-Cognitive Factors and Intentions to Receive HPV Vaccination Among Young Women?

Drawing upon health behavior change theories, the current study examined whether self-efficacy mediated relationships between social-cognitive factors (i.e., perceived risk, perceived benefits, perceived barriers, perceived severity, and cue to action) and human papillomavirus (HPV) vaccination intentions among college women. Unvaccinated women (N = 115) aged 18 to 25 years attending a Midwestern university completed an anonymous web-based survey assessing study variables. Correlational analyses and mediation analyses were conducted. Self-efficacy mediated relationships between two social-cognitive factors (i.e., perceived barriers to HPV vaccination-indirect effect = -.16, SE = .06, 95% confidence interval [CI] = [-.31, -.06]-and perceived risk of HPV-related conditions-indirect effect = .16, SE = .09, 95% CI = [.01, .37]) and HPV vaccination intentions but was unrelated to the other three social-cognitive factors. Based on these findings, future research should test whether increasing self-efficacy through education on risk of HPV-related conditions and reducing barriers to HPV vaccination improves vaccine uptake in college women.

The feminization of HPV: How science, politics, economics and gender norms shaped U.S. HPV vaccine implementation

Human papillomavirus (HPV) can cause a number of anogenital cancers (i.e., cervical, penile, anal, vaginal, vulvar) and genital warts. A decade ago, the HPV vaccine was approved, and has been shown to be a public health achievement that can reduce the morbidity and mortality for HPV-associated diseases. Yet, the mistaken over-identification of HPV as a female-specific disease has resulted in the feminization of HPV and HPV vaccines. In this critical review, we trace the evolution of the intersection of science, politics, economics and gender norms during the original HPV vaccine approval, marketing era, and implementation. Given the focus on cervical cancer screening, women were identified as bearing the burden of HPV infection and its related illnesses, and the group responsible for prevention. We also describe the consequences of the feminization of HPV, which has resulted primarily in reduced protection from HPV-related illnesses for males. We propose a multilevel approach to normalizing HPV vaccines as an important aspect of overall health for both genders. This process must engage multiple stakeholders, including providers, parents, patients, professional organizations, public health agencies, policymakers, researchers, and community-based organizations.

Human Papillomavirus Vaccination and Age at First Sexual Activity, National Health and Nutrition Examination Survey

The National Health and Nutrition Examination Survey (NHANES) collects information on human papillomavirus (HPV) vaccination history as well as sexual activity. We evaluated data from NHANES to assess report of HPV vaccination with ≥1 dose and 3 doses among females and males aged 11 to 26 years during 2007-2014. We also examined age at first vaccine dose and age at first sexual activity among females aged 14 to 26 years. Vaccination significantly increased in females aged 13 to 26 years, but not among 11- to 12-year-old girls, and remained low for both females and males. In NHANES 2011-2014, among females with known age at first vaccine dose, 43.1% reported having had sex before or in the same year they received their first HPV vaccine, and this varied by race/ethnicity. Clinicians should provide strong recommendations consistent with guidelines, including routine vaccination of girls and boys at age 11 or 12 years.

"We've Been Together. We Don't Have It. We're Fine." How Relationship Status Impacts Human Papillomavirus Vaccine Behavior among Young Adult Women

BACKGROUND

Vaccination against the human papillomavirus (HPV) has the potential to significantly reduce morbidity and mortality associated with genital warts and HPV-related cancers. However, HPV vaccination rates continue to be suboptimal among the "catch-up" population of 18- to 26-year-old women. One consistent risk factor for nonvaccination is being in a relationship. This study aimed to understand how relationship status and vaccination status impact risk perceptions and perceived need for the HPV vaccine among young adult women.

METHODS

In-depth interviews were conducted with a sample (n = 50) of recently HPV vaccinated and unvaccinated college women, and stratified by four relationship categories. Comparative thematic analysis was used to assess relationship status and HPV risk perceptions.

RESULTS

Women in relationships perceived their risk of HPV to be low, which they attributed to monogamy and few sexual partners. Women in dating relationships reported higher HPV risk, which was linked to unprotected sex and sexual activity. In contrast, single women stated that their low risk for HPV was due to sexual inactivity.

CONCLUSIONS

This study builds on the epidemiological literature, by understanding how relationship status impacts HPV vaccination among young adult women. Relationship status contributed to HPV risk perceptions and vaccination decisions among these women. Perceptions were framed based on sexual behavior, such as monogamy or number of sexual partners. Future efforts should tailor health messages to young adult women's specific risk misperceptions about HPV.

Determinants of geographic inequalities in HPV vaccination in the most populated region of France

BACKGROUND

In France, there are recommendations and reimbursements for human papillomavirus (HPV) vaccination but no HPV vaccination programs. Therefore, vaccination is largely determined by parents' initiative, which can lead to inequalities. The objective of this study was to determine the factors associated with poorer vaccination coverage rates in the most populated region of France.

METHODS

The data of this study were obtained from the National Health Insurance between 2011 and 2013. Correlations between vaccination initiation rate (at least 1 dose reimbursed) and socio-demographic/cultural factors were assessed using Pearson's product-moment correlation coefficient. Multivariate analyses were performed using logistic regression.

RESULTS

In total, 121,636 girls received at least one HPV vaccine dose. The vaccination rate for girls born from 1996 to 1999 was 18.7%. Disparities in vaccination coverage rates were observed between the 8 departments of the region, ranging from 12.9% to 22.6%. At the department level, unemployment, proportion of immigrants and foreigners, and coverage by CMU health insurance ("Couverture Maladie Universelle", a health insurance plan for those who are not otherwise covered through business or employment and who have a low income) were significantly inversely correlated with vaccination rates, whereas urban residence, medical density, income and use of medical services were not related to coverage. In the multivariate model, only the percentage of foreigners remained independently associated with lower vaccination coverage. At the individual level, the use of medical services was a strong driver of HPV vaccination initiation.

CONCLUSION

We observed geographic disparities in HPV vaccination initiation coverage. Even if no clear factor was identified as a vaccination determinant, we observed a failure of vaccination only based on parents' initiative. Therefore, an organized policy on HPV vaccination, such as school-based programs, can help improve coverage rates.

Factors Associated with Human Papillomavirus Vaccination Status at U.S. Colleges and Universities

Human papillomavirus (HPV) vaccination rates remain low, but college student vaccination could offset this trend. This study identifies characteristics that could enhance HPV vaccination among U.S. college students. Data were from the National College Health Assessment II survey (fall 2012, N = 18,919). Univariate and logistic regression analyses were used to examine associations among demographic characteristics, college region and size, health status, receipt of health services, sexual health information, and HPV vaccination status. Among women, ethnic minorities, students attending schools in the South, those not receiving routine gynecological care in the past 12 months, and those unsure of when they last received gynecological care were less likely to report HPV vaccination. Among men, African Americans, students attending schools in the South and West, and those receiving sexually transmitted infection information were more likely to report vaccination. Data suggest that college health education can help to improve U.S. HPV vaccination rates. Campus health practitioners providing sexual health information and referrals are positioned to assist in this effort.

Human papillomavirus vaccine information, motivation, and behavioral skills among young adult US women

This study elicited the information needs, motivations, and behavioral skills related to human papillomavirus vaccine decision-making among young adult women. Interviews were conducted with college women, aged 18-26 years, and stratified by recently vaccinated ( N = 25) and unvaccinated ( N = 25). Comparative thematic analysis using the Information, Motivation, and Behavioral Skills Model was conducted. Healthcare providers were identified as the most trusted sources for information. While unvaccinated women did not have experience receiving the vaccine, they reported the same procedural knowledge for vaccination. These findings suggest that young adult women have the information and procedural knowledge for human papillomavirus vaccination, but motivations may influence their decision-making.

Trends and predictors of HPV vaccination among U.S. College women and men

BACKGROUND

HPV vaccination was recommended by the Advisory Committee on Immunization Practices for young adult females in 2006 and males in 2011 to prevent HPV-related cancers and genital warts. As this prevention mechanism continues to disseminate, it is necessary to monitor the uptake of this vaccine. College students represent an important population for HPV vaccination efforts and surveillance due to increased risk for HPV infection and representing a priority population for catch-up HPV vaccination. The purpose of this study was to assess the trends in HPV vaccination among U.S. college females and males from 2009 to 2013, and to examine whether predictors for HPV vaccination differ between males and females.

METHODS

The National College Health Assessment-II (Fall 2009-2013) was used to assess trends in HPV vaccination using hierarchical logistic regression across genders and demographics. Data from 2013 were used to assess demographic variables associated with HPV vaccination for males and females, respectively. The analysis was conducted in 2015.

RESULTS

Females had nearly double the rates of HPV vaccination compared to males over time. All demographic sub-groups had significant increases in vaccine rates over time, with select male sub-groups having more accelerated increases (e.g., gay). Young age (18-21 vs. 22-26years) was a significant predictor for HPV vaccination among males and females, while race/ethnicity was a predictor of vaccination among females only.

CONCLUSIONS

These findings identified specific demographic sub-groups that need continued support for HPV vaccination. Campus health centers may be rational settings to facilitate clinical opportunities for HPV vaccination among unvaccinated college students.

The Impact of Socio-Economic Determinants on the Vaccination Rates with Rotavirus and Human Papiloma Virus Vaccine

BACKGROUND

Socio-economic inequalities may have an impact on the uptake of selfpaid vaccines. The aim of the study was to identify the effect of some socio economic determinants on vaccination rates with self-paid human papilloma virus (HPV) and rotavirus (RV) vaccines.

METHODS

Vaccination coverage data, available in electronic database cepljenje.net (administered by the National Institute of Public Health), were collected at administrative unit level. The socio-economic determinants (the average gross pay in euros, the unemployment rate, the educational and households structure, the population density, the number of inhabitants, the number of children aged from 0 to 4, the number of women aged from 15 to 30) were extracted from Statistical Office of the Republic of Slovenia web page. The strength of the correlation between socioeconomic variables and self-paid HPV and RV vaccination rates was determined.

RESULTS

Rotavirus vaccination rates show a slight negative correlation with the number of residents per administrative unit (ρ=-0.29, p=0.04), and no correlation with other socio-economic variables. Likewise, no correlation has been found between HPV vaccination rates and the selected socio-economic variables.

CONCLUSION

Ecological study did not reveal any correlations between socio economic variables and vaccination rates with RV and HPV self-paid vaccines on administrative unit level.

HPV Vaccination Completion and Compliance with Recommended Dosing Intervals Among Female and Male Adolescents in an Inner-City Community Health Center

Human papillomavirus (HPV) vaccination continues to lag behind other adolescent vaccines, especially in areas with pervasive disparities in HPV-related cancers. The purpose of this study was to examine HPV vaccine completion and dosing intervals among low-income adolescents in urban areas. The study included electronic health record data on HPV vaccination for 872 adolescents who received at least one dose of the HPV vaccine. Only 28.4% completed the 3-dose series. For the whole sample, HPV vaccine completion was higher for non-English speakers and among adolescents seen at Newark-South and East Orange sites. Completion was higher among non-English speaking female and Hispanic adolescents, females seen in Newark-South and East Orange sites, and insured Black adolescents. Completion was also dramatically lower among non-English speaking Black adolescents seen at Newark-North, Irvington, and Orange sites (12.5%) compared to other Black adolescents (22.0-44.4%). The mean dosing intervals were 5.5 months (SD = 4.6) between dose 1 and 2 and 10 months (SD = 6.1) between dose 1 and 3. Longer durations between vaccine doses were found among uninsured adolescents and those seen at Newark-North, Irvington, and Orange sites. Non-English speakers had longer duration between dose 1 and 3. Further, durations between dose 1 and 3 were dramatically longer among insured adolescents seen at Newark-North, Irvington, and Orange locations for the whole sample (M = 11.70; SD = 7.12) and among Hispanic adolescents (M = 13.45; SD = 8.54). Understanding how the study predictors facilitate or impede HPV vaccination is critical to reducing disparities in cervical and other HPV-related cancer, especially among Black, Hispanic, and low-income populations.

Preventing Cervical Cancer in the United States: Barriers and Resolutions for HPV Vaccination

Human papillomavirus (HPV) vaccination rates for preadolescent and adolescent girls in the United States are far behind those of other developed nations. These rates differ substantially by region and state, socioeconomic status, and insurance status. In parents and young women, a lack of awareness and a misperception of the risk of this vaccine drive low vaccination rates. In physicians, lack of comfort with discussion of sexuality and the perception that the vaccine should be delayed to a later age contribute to low vaccination rates. Patient- and physician-targeted educational campaigns, systems-based interventions, and school-based vaccine clinics offer a variety of ways to address the barriers to HPV vaccination. A diverse and culturally appropriate approach to promoting vaccine uptake has the potential to significantly improve vaccination rates in order to reach the Healthy People 2020 goal of over 80% vaccination in adolescent girls. This article reviews the disparities in HPV vaccination rates in girls in the United States, the influences of patients’, physicians’, and parents’ attitudes on vaccine uptake, and the proposed interventions that may help the United States reach its goal for vaccine coverage.

The role of anticipated regret and health beliefs in HPV vaccination intentions among young adults

Although cognitions have predicted young adults' human papillomavirus (HPV) vaccine decision-making, emotion-based theories of healthcare decision-making suggest that anticipatory emotions may be more predictive. This study examined whether anticipated regret was associated with young adults' intentions to receive the HPV vaccine above and beyond the effects of commonly studied cognitions. Unvaccinated undergraduates (N = 233) completed a survey assessing Health Belief Model (HBM) variables (i.e., perceived severity of HPV-related diseases, perceived risk of developing these diseases, and perceived benefits of HPV vaccination), anticipatory emotions (i.e., anticipated regret if one were unvaccinated and later developed genital warts or HPV-related cancer), and HPV vaccine intentions. Anticipated regret was associated with HPV vaccine intentions above and beyond the effects of HBM variables among men. Among women, neither anticipated regret nor HBM variables showed consistent associations with HPV vaccine intentions. Findings suggest that anticipatory emotions should be considered when designing interventions to increase HPV vaccination among college men.

Estimating human papillomavirus vaccination coverage among young women in Victoria and reasons for non-vaccination

Background Adult Australian women aged 18 to 26 years were offered human papillomavirus (HPV) vaccine in a mass catch up campaign between 2007 and 2009. Not all doses administered were notified to Australia’s HPV vaccine register and not all young women commenced or completed the vaccine course. Methods: We surveyed vaccine age-eligible women as part of the Victorian Population Health Survey 2011–2012, a population based telephone survey, to ascertain self-reported vaccine uptake and reasons for non-vaccination or non-completion of vaccination among young women resident in the state of Victoria, Australia. Results: Among 956 women surveyed, 62.3 per cent (57.8–66.6%) had been vaccinated against HPV and coverage with three doses was estimated at 53.7 per cent (49.1–58.2%). These estimates are higher than register-based estimates for the same cohort, which were 57.8 per cent and 37.2 per cent respectively. A lack of awareness about needing three doses and simply forgetting, rather than fear or experience of side effects, were the most common reasons for failure to complete all three doses. Among women who were not vaccinated, the most frequent reasons were not knowing the vaccine was available, perceiving they were too old to benefit, or not being resident in Australia at the time. Conclusions: It is likely that at least half of Victoria’s young women were vaccinated during the catch-up program. This high level of coverage is likely to explain the marked reductions in HPV infection, genital warts and cervical disease already observed in young women in Victoria.

Prevalence and predictors of human papillomavirus (HPV) vaccination among young women surviving childhood cancer

PURPOSE

Human papillomavirus (HPV) is a sexually transmitted infection and the cause of cervical and other cancers. Vaccination is available to protect against genital HPV and is recommended for individuals aged 9-26 years. This study aimed to estimate the prevalence of HPV vaccination among childhood cancer survivors and to identify factors associated with vaccine outcomes.

METHODS

Young adult females with (n = 114; M age = 21.18 years, SD = 2.48) and without (n = 98; M age = 20.65 years, SD = 2.29) a childhood cancer history completed surveys querying HPV vaccination initiation/completion, as well as sociodemographic, medical, and health belief factors. Multivariable logistic regression was used to calculate odds ratios (ORs) and 95 % confidence intervals (CIs) for vaccine outcomes.

RESULTS

Among survivors, 38.6 % (44/114) and 26.3 % (30/114) initiated or completed vaccination compared to 44.9 % (44/98) and 28.6 % (28/98) among controls, respectively. In the combined survivor/control group, physician recommendation (OR = 11.24, 95 % CI 3.15-40.14) and familial HPV communication (OR = 7.28, 95 % CI 1.89-28.05) associated with vaccine initiation. Perceptions of vaccine benefit associated with vaccine completion (OR = 10.55, 95 % CI 1.59-69.92), whereas perceptions of HPV-related severity associated with non-completion (OR = 0.14, 95 % CI 0.03-0.71).

CONCLUSION

Despite their increased risk for HPV-related complication, a minority of childhood cancer survivors have initiated or completed HPV vaccination. Modifiable factors associated with vaccine outcomes were identified.

IMPLICATIONS FOR CANCER SURVIVORS

HPV vaccination is a useful tool for cancer prevention in survivorship, and interventions to increase vaccine uptake are warranted.

Initiation of Human Papillomavirus Vaccination Among Predominantly Minority Female and Male Adolescents at Inner-City Community Health Centers

OBJECTIVES

We examined the prevalence and correlates of human papillomavirus (HPV) vaccine initiation among adolescents in low-income, urban areas.

METHODS

The study consisted of electronic health record data on HPV vaccination for 3180 adolescents (aged 10-20 years) at a multisite community health center in 2011.

RESULTS

Only 27% initiated the HPV vaccine. The adjusted odds ratio (AOR) of HPV vaccination was lower among older adolescents (AOR = 0.552; 95% confidence interval [CI] = 0.424, 0.718) and those seen by nonpediatric health care providers (HCPs; AOR = 0.311; 95% CI = 0.222, 0.435), and higher among non-English speakers (AOR = 1.409; 95% CI = 1.134, 1.751) and those seen at 2 site locations (AOR = 1.890; 95% CI = 1.547, 2.311). Insurance status was significant only among female and Hispanic adolescents. Language was not a predictor among Hispanic adolescents. Across all analyses, the interaction of age and HCP specialty was associated with HPV vaccination. Dramatically lower HPV vaccination rates were found among older adolescents seen by nonpediatric HCPs (3%-5%) than among other adolescents (23%-45%).

CONCLUSIONS

Improving HPV vaccination initiation in low-income urban areas is critical to reducing disparities in cervical and other HPV-related cancer, especially among Black, Hispanic, and low-income populations.

Factors related to vaccine uptake by young adult women in the catch-up phase of the National HPV Vaccination Program in Australia: Results from an observational study

BACKGROUND

Australia commenced a publically-funded, National Human Papillomavirus (HPV) Vaccination Program in 2007 with a two year catch-up phase for females aged 12-26 years.

OBJECTIVE

To identify the factors associated with the uptake of the HPV vaccine (which has a recommended 3-dose schedule in Australia) by young adult women vaccinated by general practitioners and community-based programs within the catch-up phase.

METHODS

1139 women who were eligible to receive the free HPV vaccine during the catch-up period were recruited in 2008-2009 (age 20-29 years at recruitment), in New South Wales, after having a normal (negative) cervical smear result recorded on the NSW Pap Test Register. Participants completed a self-administered questionnaire providing information on vaccination status, and sociodemographic and other factors.

RESULTS

Overall, 880 (77%) women reported receiving ≥ 1 dose of the vaccine and 777 women (68%) reported receiving ≥ 2 doses. In multivariable analysis (adjusting for the period for which each woman was eligible for free HPV vaccination), uptake of ≥ 1 dose of the vaccine was significantly associated with being born in Australia (p < 0.01), being single (p = 0.02), being nulliparous (p < 0.01), living in a higher socioeconomic status area (p-trend = 0.03), living in more remote areas (p = 0.03), drinking alcohol (p < 0.01) and using hormonal contraceptives (p < 0.01). Although vaccinated women were more likely to have fewer sexual partners than unvaccinated women (p-trend = 0.02), they were also more likely to report a prior sexually transmitted infection (STI) (p = 0.03). Similar factors were associated with receiving ≥ 2 doses.

CONCLUSIONS

In this group, women living in higher socioeconomic status areas were more likely to be vaccinated against HPV in the catch-up phase of the national program. Although vaccinated women tended to have fewer sexual partners, they also reported prior STIs, which may be a marker of increased risk of prior exposure to HPV. The findings of this study reinforce the continuing need to prioritise equitable delivery of vaccination to various population subgroups.

Human papillomavirus vaccination for men: advancing policy and practice

ABSTRACT 

The quadrivalent HPV vaccine (HPV4) is safe and highly efficacious, and can significantly reduce the burden of HPV-related genital warts and cancers among men, in addition to promoting herd immunity. Nevertheless, HPV4 coverage among boys remains low in most settings. Research to date has focused predominantly on HPV vaccination of girls to prevent cervical cancer. Most countries with publicly funded healthcare where HPV4 is licensed cover the costs of HPV vaccination programs for girls only. We critically review the evidence for extending publicly funded HPV vaccination programs to boys in addition to girls. After an overview of research on HPV prevalence and associated cancers among men, we review cost–effectiveness studies, benefits of universal versus targeted vaccination approaches and multifaceted health equity concerns, along with directions in vaccine delivery programs and intervention research to promote HPV vaccine uptake for boys. Comprehensive evaluation of the systematic exclusion of boys from publicly financed HPV vaccination programs is warranted given tremendous public health implications of new infections and subsequent cancers that could have otherwise been averted.

Emergency medicine physician attitudes toward HPV vaccine uptake in an emergency department setting

A physician's recommendation is the most effective published method of motivating HPV vaccination initiation. The emergency department (ED) is the 'public health safety net', and often the only access to care for underserved populations. Recommendation of the HPV vaccine in the ED is a potential avenue to improve vaccination rates among sub-populations who do not have access to routine medical care. We assessed willingness of EM physicians to recommend the vaccine, target high-risk women, and disclose perceived barriers to vaccination in the ED. A cross sectional study using an 11-item survey, was used to assess physician attitudes toward recommending the HPV vaccine in an ED setting to age eligible patients. 67.4% stated they would recommend the vaccine, 23.9% were neutral, and 8.7% would not recommend the vaccine to age eligible patients in the ED. 41% noted lack of adequate reimbursement for vaccination as a barrier to vaccination in the ED (P<0.05). Physicians were comfortable targeting women at high risk for cervical cancer for vaccination (P<0.05). EM physicians are comfortable targeting high-risk women for HPV vaccination in an ED setting. Support of EM physicians in the national effort to improve HPV vaccine uptake is an important step in eradicating a largely preventable yet lethal cancer.
