Item Assessing the Effectiveness of Web-Based Modules on Human Papillomavirus Among Dental and Dental Hygiene Students(Springer, 2023) Shukla, Anubhuti; Chintapalli, Aparna; Ahmed, Mohammed Khader Alisha Bin; Welch, Kelly; Villa, Alessandro; Cariology, Operative Dentistry and Dental Public Health, School of DentistryLiterature suggests that deficiencies among dental professional students in both knowledge and awareness of human papillomavirus (HPV) and its association with oropharyngeal cancers (OPC), as well as its risk factors implicating the prevalence of HPV, may be due to the lack of HPV-related education during professional schooling. The aim of this study was to assess the effectiveness of an online learning tool to educate dental and dental hygiene students about HPV and its association with OPC, rapidly evolving disease patterns, and dental professionals' role in HPV-associated OPC prevention efforts. A three-section online learning module was developed to improve dental professionals' comfort levels with, and knowledge of, HPV. The participants were recruited to participate in surveys before and after the intervention. Descriptive statistics and chi-square analysis were computed to study the effectiveness of the modules in improving the knowledge of students about this topic. Pre-intervention survey participants totaled 142, and 107 participants answered the post-intervention survey. The majority of the study participants had some baseline understanding of HPV prior to accessing the modules. After reviewing the modules, there was a statistically significant increase in the proportion of respondents who identified OPC (p = 0.01), vaginal cancer (0.02), vulvar cancer (0.04), and penile cancer (0.01) as associated with HPV. A gap in the understanding of HPV vaccine-eligible groups was noted in almost half of the participants; while most participants could correctly identify that boys and girls aged 9-12 years were eligible to get the vaccine, the gap in knowledge in this regard was related to "25-year-old with an abnormal pap result." Due to the evolving nature of this topic, there is a need to find new and effective methods of disseminating HPV-related information among the existing and future dental workforce.Item Coadministration of a 9-Valent Human Papillomavirus Vaccine With Meningococcal and Tdap Vaccines(AAP, 2015-07) Schilling, Andrea; Parra, Mercedes Macias; Gutierrez, Maricruz; Restrepo, Jaime; Ucros, Santiago; Herrera, Teobaldo; Engel, Eli; Huicho, Luis; Shew, Marcia; Maansson, Roger; Caldwell, Nicole; Luxembourg, Alain; ter Meulen, Ajoke Sobanjo; Department of Pediatrics, IU School of MedicineBACKGROUND: This study in 11- to 15-year-old boys and girls compared the immunogenicity and safety of GARDASIL 9 (9-valent human papillomavirus [9vHPV] vaccine) administered either concomitantly or nonconcomitantly with 2 vaccines routinely administered in this age group (Menactra [MCV4; Neisseria meningitidis serotypes A/C/Y/W-135] or Adacel [Tdap; diphtheria/tetanus/acellular pertussis]). METHODS: Participants received 9vHPV vaccine at day 1 and months 2 and 6; the concomitant group (n = 621) received MCV4/Tdap concomitantly with 9vHPV vaccine at day 1; the nonconcomitant group (n = 620) received MCV4/Tdap at month 1. Antibodies to HPV-, MCV4-, and Tdap-relevant antigens were determined. Injection-site and systemic adverse events (AEs) were monitored for 15 days after any vaccination; serious AEs were monitored throughout the study. RESULTS: The geometric mean titers for all HPV types in 9vHPV vaccine 4 weeks after dose 3, proportion of subjects with a fourfold rise or greater in titers for 4 N meningitidis serotypes 4 weeks after injection with MCV4, proportion of subjects with antibody titers to diphtheria and tetanus ≥0.1 IU/mL, and geometric mean titers for pertussis antigens 4 weeks after injection with Tdap were all noninferior in the concomitant group compared with the nonconcomitant group. Injection-site swelling occurred more frequently in the concomitant group. There were no vaccine-related serious AEs. CONCLUSIONS: Concomitant administration of 9vHPV vaccine with MCV4/Tdap was generally well tolerated and did not interfere with the antibody response to any of these vaccines. This strategy would minimize the number of visits required to deliver each vaccine individually.Item Evaluation methods for vaccination campaigns on college campuses: A scoping review(Elsevier, 2022-12) Carr, Alexcia; Pittman , Eric; Imeri , Hyllore; Nasruddin , Saara; Sparkmon, Wesley; Head, Katharine J.; Vivo, Sarah; Barnard , Marie; Communication Studies, School of Liberal ArtsBackground Vaccinations are successful, cost-effective tools to prevent the spread of certain infectious diseases. Many colleges conduct vaccination campaigns on their campuses for various vaccine-preventable diseases, including measles, mumps, influenza, HPV, and most recently, for SARS-CoV-2, the virus responsible for COVID-19. Implementing these campaigns requires substantial effort and understanding their effectiveness is an important factor in justifying these programs. Aim This scoping review aims to identify, review, and summarize existing evaluation methods for vaccination campaigns on college campuses in order to provide evaluation guidance for institutions planning future vaccination campaigns. Methods Publications that focused on vaccination campaigns on college campuses for students and/or faculty and staff and described their evaluation methods were included in our analysis. A systematic search of the literature identified 2,101 articles. After duplicates were removed, titles and abstracts were screened, and references searched, 43 articles were identified for full-text review. Sixteen articles provided evaluation information and were systematically reviewed. Results Interventions targeted a variety of vaccine-preventable diseases, with the majority either aiming to increase HPV vaccine uptake or vaccinate against meningococcal serogroups. Most studies reported on campaigns that included both educational activities and provided vaccinations. Evaluation methods varied widely. Some studies measured vaccine-related knowledge and attitudes. Vaccine uptake was most commonly measured as a simple count of doses administered. Conclusions College campus vaccination campaigns are evaluated in multiple ways, with little consistency in how the effectiveness of campaigns are measured. There is a need to develop clear evaluation methods for college vaccination programs, especially how to calculate vaccination rates associated with these efforts.Item HPV Vaccine Awareness, Past Behaviors, and Future Intentions Among a Diverse Sample of Fathers Aged 27 to 45 Years: A National Survey(Sage, 2024) Quist, Kevin M.; Fontenot, Holly B.; Zimet, Gregory; Lim, Eunjung; Matsunaga, Masako; Liebermann, Erica; Allen, Jennifer D.; Pediatrics, School of MedicineMen aged 27 to 45 are eligible for human papillomavirus (HPV) vaccination as of 2019, yet relatively little is known about whether they have received or intend to receive it. We conducted a cross-sectional, online survey among fathers aged 27 to 45 between March and April 2022, to assess associations between HPV vaccination awareness, behaviors, intentions, and psychosocial constructs from the Health Belief Model. We examined the characteristics of those who had (a) heard of the HPV vaccine, (b) already received ≥ 1 dose, and (c) intentions for future vaccination among those who had never been vaccinated. Among 400 men who completed the survey, 32% were not aware of the HPV vaccine. Among those who were aware, 41% had received ≥ 1 dose. Sixty-three percent of unvaccinated men reported that they intended to get vaccinated in the future. Multivariable logistic regression analyses revealed that age and race/ethnicity were associated with having been vaccinated previously. Among the unvaccinated, multivariable logistic regression analyses revealed that those with a higher perceived risk of HPV-associated cancer had 3.73 greater odds of reporting they would seek vaccination compared to those with lower perceived risk (95% confidence interval [CI] = [1.28, 12.3]). We did not find perceived benefits, barriers, or decision self-efficacy to be related to future vaccine intentions. Since recommendations for this group include shared clinical decision-making, public health efforts should focus on raising awareness of vaccine eligibility, emphasizing risk factors for HPV-associated cancers so that individuals have an accurate perception of risk, and encouraging conversation between men and their providers.Item Human Papillomavirus Vaccine Communication: Perspectives of 11–12 Year-Old Girls, Mothers, and Clinicians(Elsevier, 2013) Kowalczyk Mullins, Tanya L.; Griffioen, Anne M.; Glynn, Susan; Zimet, Gregory D.; Rosenthal, Susan L.; Fortenberry, J. Dennis; Kahn, Jessica A.; Pediatrics, School of MedicineObjectives: Because little is known about the content of human papillomavirus (HPV) vaccine-related discussions with young adolescent girls in clinical settings, we explored communication between 11- and 12 year-old girls, mothers, and clinicians regarding HPV vaccines and concordance in reports of maternal and clinician communication. Methods: We conducted individual interviews with 33 girls who had received the quadrivalent HPV vaccine in urban and suburban clinical settings, their mothers, and their clinicians. Data were analyzed using qualitative methods. Results: From the perspectives of both girls and mothers, clinicians and parents were the preferred sources of HPV vaccine information for girls. Vaccine efficacy and risks/benefits of vaccination were the most commonly reported desired and actual topics of discussion by mothers, girls, and clinicians. Clinician recommendation of vaccination was reported by nearly one-fifth of girls and nearly half of mothers. The most common concordant messages were related to efficacy of the vaccine, with concordance in 70% of triads. The most common discordant messages were related to sexual health. Approximately half of clinicians (16) reported discussing sexual health, but only 5 mothers (15%) and 4 girls (12%) reported this. Triads recruited from suburban (vs. urban) practices had higher degrees of concordance in reported vaccination communication. Conclusions: HPV vaccine efficacy and safety are important topics for clinicians to discuss with both girls and mothers; educating mothers is important because parents are a preferred source of vaccine-related information for girls. Because girls may be missing important vaccine-related messages, they should be encouraged to actively engage in vaccine discussions.Item Increasing Efforts to Reduce Cervical Cancer Through State-Level Comprehensive Cancer Control Planning(2015-07) Meyerson, Beth E.; Zimet, Gregory D.; Multani, Gurprit S.; Levell, Caleb; Lawrence, Carrie A.; Smith, Jennifer S.; Department of Medicine, IU School of MedicineReducing cervical cancer disparities in the United States requires intentional focus on structural barriers such as systems and policy that impact access to human papillomavirus (HPV) vaccination, cervical cancer screening, and treatment. Such changes are difficult and often politicized. State comprehensive cancer control (CCC) plans are vehicles that, if designed well, can help build collective focus on structural changes. Study objectives were to identify the prioritization of cervical cancer in state CCC plans, the conceptualization of HPV within these plans, and the focus of plans on structural changes to reduce cervical cancer disparities. Data were gathered by systematic content analysis of CCC plans from 50 states and the District of Columbia from February–June 2014 for evidence of cervical cancer prioritization, conceptualization of HPV, and focus on structural barriers to cervical cancer vaccination, screening or treatment. Findings indicate that prioritization of cervical cancer within state CCC plans may not be a strong indicator of state efforts to reduce screening and treatment disparities. While a majority of plans reflected scientific evidence that HPV causes cervical and other cancers, they did not focus on structural elements impacting access to evidence-based interventions. Opportunities exist to improve state CCC plans by increasing their focus on structural interventions that impact cervical cancer prevention, detection, and treatment, particularly for the 41% of plans ending in 2015 and the 31% ending between 2016 and 2020. Future studies should focus on the use of policy tools in state CCC plans and their application to cervical cancer prevention and treatment.Item IUPUI Center for HPV Research: Effects of a Brief Health Messaging Intervention on HPV Vaccine Acceptability among Parents of Adolescent Sons(Office of the Vice Chancellor for Research, 2014-04-11) Donahue, Kelly; Stupiansky, Nathan; Cox, Anthony; Cox, Dena; Zimet, GregoryBackground: Human papillomavirus (HPV) is an very common infection that is a primary cause of warts and many cancers, including cervical, anal, vaginal, vulvar, penile, and head and neck cancers. In an effort to address the problems associated with HPV infection and prevention, the Center for HPV Research at IUPUI (Zimet & Fortenberry, Co-Directors) fosters collaboration among investigators from multiple disciplines and departments at IUPUI, IU Bloomington, Purdue University, and University of Notre Dame. There currently are 25 faculty and 7 pre- and post-doctoral trainees who are members of the Center. The Center for HPV Research was established in July, 2012 with funds from the IUPUI Signature Center Initiative, The Department of Pediatrics, and the IU Simon Cancer Center. In this abstract we highlight a study representing a collaboration among 5 center members, including our current center-supported post-doc. Objectives: HPV vaccination coverage remains very low among adolescent males in the U.S. We explored the effect of brief Web-based health messages on parents’ willingness to vaccinate their sons against HPV. Methods: A U.S. national sample of parents of 11-17-year-old sons (N=779) completed a Web-based survey assessing attitudes and behaviors related to HPV vaccination. Parents of non-vaccinated sons (79% of the sample) were randomized to a two-level normalizing message (NM) condition: no message vs. NM (“Millions of doses of the vaccine have been administered to adolescent girls in the US at this time.”) and a three-level protection message (PM) condition: no message vs. son-only PM (“The HPV vaccine can protect your son from most kinds of genital warts and anal cancers,”) vs. son+partner PM (son-only message plus “If your son gets vaccinated it can also protect his future spouse from genital warts and cancer.”). Parents then reported willingness to vaccinate their sons against HPV on a scale of 1-100. Intervention effects were analyzed using a 2×3 between-subjects ANOVA. Results: Mean willingness was 55.2 (SD=29.7). A significant interaction was found between health messaging conditions, F(2,576) = 3.17, p = 0.043). Parents receiving the son-only PM reported significantly lower willingness if they received the NM vs. no NM (p=.014). Parents receiving no NM reported significantly higher willingness if they received the son + partner PM vs. no PM (p=.029). Conclusions: Reading brief online health messages affected parents’ willingness to vaccinate their adolescent sons against HPV. Overall, presenting normalizing information pertaining to adolescent females (for whom routine immunization was first recommended) appeared to lower parent willingness to vaccinate their adolescent sons. Presenting information about protecting their son and/or son’s partner against HPV-associated outcomes appeared to increase parent willingness to vaccinate in the absence of such normalizing information.Item The IUPUI Center for HPV Research: Updates 2014-2015(Office of the Vice Chancellor for Research, 2015-04-17) Zimet, Gregory D.; Fortenberry, J. DennisBackground: Human papillomavirus (HPV) is a very common infection. High risk (HR) HPV types (particularly types 16 & 18) are causally implicated in many cancers, including cervical, anal, vaginal, vulvar, penile, and head and neck cancers. In an effort to address the problems associated with HPV infection and prevention, the Center for HPV Research at IUPUI (Zimet & Fortenberry, Co-Directors) fosters collaboration among investigators from multiple disciplines and departments at IUPUI, IU Bloomington, Purdue University, and University of Notre Dame. There currently are 32 faculty and 8 pre- and post-doctoral fellows who are members of the Center. The Center for HPV Research was established in July, 2012 with funds from the IUPUI Signature Center Initiative, the Department of Pediatrics, and the IU Simon Cancer Center. Over the past year, Center members had 6 external & internal grants funded, 5 additional grants submitted, 8 peer-reviewed articles published, and gave over 20 scientific conference and invited presentations. In this abstract we highlight a study representing a collaboration among 5 center members, with Dr. Marcia Shew as the lead and including an MPH student. Objectives: Most HR HPV infections do not progress to cancer, but progression is associated with persistent infection. HPV was previously thought to "clear" or persist, but newer studies suggest that HPV may be a latent virus that can be re-detected episodically. This study examined the persistence and/or redetection of HR HPV in young women recruited 6 years after identification of a HR HPV infection during their prior involvement in a longitudinal study of adolescent women. Methods: 30 women from the prior study (the Young Women’s Project) were recruited for 2 visits, 6 weeks apart. During Visit 1 they had a Pap test, HPV DNA testing, HPV serology, and were administered a semi-structured interview. During Visit 2, Pap test results were given, a self-swab for HPV testing was obtained, and a qualitative interview was administered. Results: 15 women had normal Pap test results, 2 were ASCUS, and 3 LGSIL. 12 women had a history of colposcopy for a previous abnormal Pap results and 4 had received treatment for cervical dysplasia. 26 of the women had HPV 16 in the original YWP study. 11 had HPV 16 redetected in the present study, including in 6 women who had apparently "cleared" the infection during the original YWP study. Conclusions: High risk HPV may not always (or ever) "clear" Persistent low viral levels may not be detectible. However, some HPV infections may be episodically detected if changes in immune function lead to increases in viral copies. Questions raised by this research include: 1) who is at risk for episodic detection?; 2) what factors are predictive of episodic detection?; 3) how likely is episodically-detect HR HPV to progress to cervical disease?; 4) what is the predictive value of a negative HPV DNA test?; and 5) what do we tell women with a positive HR HPV DNA screen if they have been sexually abstinent or with a life-long partner ... or if they have a new partner?Item A model of health care provider decision making about HPV vaccination in adolescent males(Elsevier, 2015-08) Alexander, Andreia B.; Best, Candace; Stupiansky, Nathan; Zimet, Gregory D.; Department of Pediatrics, IU School of MedicineIntroduction In the U.S., HPV vaccination of adolescent males remains low, despite the recommendation for routine vaccination. Although research has highlighted that health care provider (HCP) recommendation is very influential in HPV vaccine uptake, research on this topic in the male population is lacking. Accordingly, we used a qualitative approach to identify HCP knowledge, attitudes, and behaviors regarding adolescent male HPV vaccination, one year, after routine vaccination of adolescent males was recommended. Method A total of 20 U.S. pediatric HCPs participated in 20–30 min interviews about knowledge, attitudes, and practices regarding male HPV vaccination. Interviews were audio-recorded, transcribed and, analyzed using inductive content analysis. Results The providers had been in practice for 1–35 years, 75% were female, and 75% were White. Opinions on HPV vaccination were shaped by knowledge/perception of the risks and benefits of vaccination. Although all providers frequently offered HPV vaccine to male patients, the strength and content of the offer varied greatly. Vaccination opinions determined what issues were emphasized in the vaccine offer (e.g., stressing herd immunity, discussing prevention of genital warts), while adolescent age influenced if and how they pitched their vaccine offer (e.g., HPV as a STI). Most providers agreed with the ACIP recommendations, however, several expressed that providers’ preexisting opinions might remain unchanged despite the recommendations. Consistent with the literature on determinants of HPV vaccination, providers believed that their own recommendation was a major factor in a family's decision to vaccinate. Barriers to vaccination included the “newness” and sexual nature of the vaccine, lack of insurance coverage, and the vaccine not being mandated. Conclusions Providers’ opinions about, and approaches to offering, HPV vaccination to males were highly variable. Interventions designed to improve male HPV vaccination should focus on helping providers to routinely recommend the vaccine to all of their eligible patients, both males and females.Item Persistent Disparities in Cervical Cancer Screening Uptake: Knowledge and Sociodemographic Determinants of Papanicolaou and Human Papillomavirus Testing Among Women in the United States(Sage, 2020) Johnson, Nicole L.; Head, Katharine J.; Foxworthy Scott, Susanna; Zimet, Gregory D.; Communication Studies, School of Liberal ArtsObjectives: Cervical cancer is the second-most common type of cancer among women aged 15-44, and racial, ethnic, and economic disparities exist in survival rates despite widely available screening tests and early treatment options. The objective of this study was to describe the association among knowledge, sociodemographic characteristics, and cervical cancer screening, with the goal of developing interventions to prevent cervical cancer in populations at risk of the disease. Methods: In 2017, we conducted a nationwide survey of women in the United States aged ≥18 who had ever received a Papanicolaou (Pap) test (N = 630). We conducted t tests and one-way analysis of variance to determine sociodemographic differences (age, education, race, ethnicity, income, type of health insurance) in knowledge about cervical cancer screening (Pap test and human papillomavirus [HPV] test). We used logistic regressions to define significant determinants of cervical cancer screening behaviors in the previous 5 years. Results: Of 629 respondents, 407 (64.7%) had an annual household income <$30 000, and 322 of 536 (60.1%) respondents had government-provided health insurance. Of 630 women who had ever had a Pap test, 425 (67.5%) had an HPV test. Hispanic and non-Hispanic white women were more likely than Hispanic and non-Hispanic black women (odds ratio [OR] = 2.49; 95% CI, 1.12-4.54; P = .02) and women with government-provided health insurance (OR = 1.91; 95% CI, 1.08-3.37; P = .03) were more likely than women with private health insurance to have received a Pap test in the previous 5 years. Knowledge of HPV was a significant predictor of having received an HPV test in the previous 5 years (OR = 1.37; 95% CI, 1.22-1.54; P < .001). Conclusion: Disparities in cervical cancer screening among sociodemographic groups of women suggest the need for targeted interventions to improve knowledge about Pap and HPV tests.
