Factors Associated with HPV Vaccine Awareness in a Population-Based Sample of Hispanic Women in Puerto Rico

Perceptions of dengue risk and acceptability of a dengue vaccine in residents of Puerto Rico

Dengvaxia is the first dengue vaccine recommended in the United States (U.S.). It is recommended for children aged 9-16 y with laboratory-confirmed previous dengue infection and living in areas where dengue is endemic. We conducted focus groups with parents and in-depth interviews with key informants (i.e. practicing pediatricians, physicians from immunization clinics, university researchers, and school officials) in Puerto Rico (P.R.) to examine acceptability, barriers, and motivators to vaccinate with Dengvaxia. We also carried out informal meetings and semi-structured interviews to evaluate key messages and educational materials with pediatricians and parents. Barriers to vaccination included lack of information, distrust toward new vaccines, vaccine side effects and risks, and high cost of/lack of insurance coverage for laboratory tests and vaccines. Motivators included clear information about the vaccine, a desire to prevent future dengue infections, the experience of a previous dengue infection or awareness of dengue fatality, vaccine and laboratory tests covered by health insurance, availability of rapid test results and vaccine appointments. School officials and parents agreed parents would pay a deductible of $5-20 for Dengvaxia. For vaccine information dissemination, parents preferred an educational campaign through traditional media and social media, and one-on-one counseling of parents by healthcare providers. Education about this vaccine to healthcare providers will help them answer parents' questions. Dengvaxia acceptability in P.R. will increase by addressing motivators and barriers to vaccination and by disseminating vaccine information in plain language through spokespersons from health institutions in P.R.

Exploring Sources of Information and Religious Beliefs in Regard to HPV and Vaccination Among Hispanic/Latino College Students in the USA

We identified (a) sources of and communication about HPV information and (b) factors (e.g., religious affiliations) related to information sources and communication regarding HPV among Hispanic/Latino college students attending US institutions. Applying a cross-sectional design, we recruited 209 participants from US colleges. Most participants used healthcare professionals for their sources and communication about HPV-related information. Respondents who were practicing Catholics tended to use the Internet and healthcare professionals as their sources for HPV-related information. Healthcare professionals, TV, schoolteachers, same-sex friends, and family members affected participants' HPV vaccination, knowledge, and attitudes. Religious faith may influence information-seeking behaviors and requires more research.

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

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

Understanding parents' views toward the newly enacted HPV vaccine school entry policy in Puerto Rico: a qualitative study

BACKGROUND

The Human papillomavirus vaccine (HPV) is an essential tool for the prevention of HPV-related cancers. In Puerto Rico, the Secretary of Health established a school entry requirement of at least one dose of HPV vaccination in girls and boys aged 11 and 12 years, taking effect in August 2018. Our study aimed to examine parents' and guardians' views of unvaccinated children about the process of implementation of the new HPV vaccination school entry policy in Puerto Rico and identify potential barriers and facilitators related to the implementation of this requirement.

METHODS

During April through November 2019, we conducted three focus groups (n = 12) and eight in-depth semi-structured interviews with parents of children aged 11 and 12 who had not yet initiated the HPV vaccine series. The interview topics addressed were: perception of vaccination, HPV vaccine and it is inclusion as new school entry requirement practice, procedure of the sources of information, influencers, and willingness to change. The interviews were recorded and transcribed by our staff members. We identified emergent themes through thematic analysis.

RESULTS

The participants' perspective on the HPV vaccine school requirement was mixed. Lack of information of the HPV vaccines and lack of communication about the school-entry requirement were the themes most mentioned in the interviews. Moreover, previous negative experiences from friends or family members and adverse effects deterred some participants from vaccinating their kids. We discussed barriers in the process of soliciting an exemption.

CONCLUSION

Most barriers mentioned by study participants are modifiable. Information about the HPV vaccine mandate's implementation and educational materials regarding HPV vaccine safety need to be provided to address parents' concerns related to the vaccine's side effects. Schools (teachers, principal directors, and administrative staff), the government, and parent organizations need to be part of these efforts. This multilevel approach will help to improve disseminating information about HPV vaccination to clarify doubts and misinformation among parents.

Knowledge of HPV, its vaccines, and attitudes toward HPV vaccines among obstetrician-gynecologists, pediatricians and immunization services providers in Western China

Background

In mainland China, HPV vaccines have been available to the public. However, only a few related studies among health care providers, as the key information providers, were reported although public concerns on HPV vaccines still exist. In this study, we aim to assess the knowledge of HPV, its vaccines, and attitudes toward HPV vaccines among the three most important groups of health care providers in Western China.

Method

This was a cross-sectional questionnaire-based study. Health care providers including obstetrician-gynecologists (OB-GYNs), pediatricians, and immunization service providers in Western China were investigated regarding their knowledge of HPV and its vaccines and their attitudes toward HPV vaccines.

Results

Of 1079 health care providers completing the survey, 1015 (94.1%) knew HPV infection is the primary cause of cervical cancer. However, lower knowledge levels of other HPV-related diseases were also found (43.2%). About three-quarters (74.1%) of practitioners interviewed would be willing to recommend HPV vaccination, which was found to be lower among the OB-GYNs (69.6%) and the pediatricians (73.2%). “Lack of relevant knowledge,” “concerns on safety and efficacy” and price were the three most important concerns surrounding HPV vaccination.

Conclusion

The interviewed practitioners did not have adequate knowledge of HPV and its vaccines in depth. Education interventions are highly recommended to the health care providers, especially for OB-GYNs and pediatricians, to increase the coverage of HPV vaccination among the population. For the currently high price of vaccines, a future co-sharing mechanism between the government, the providers, and the individuals might be a solution.

¡Habla de VPH! An Educational Activity for College Students in Puerto Rico

OBJECTIVE

To evaluate human papillomavirus (HPV) infection knowledge, willingness to get vaccinated, and vaccination uptake, following a brief educational activity entitled ¡Habla de VPH! (Let's talk about HPV!) in a sample of college students at the University of Puerto Rico, Bayamón.

METHODS

Participants completed a self-administered questionnaire developed by the research team, which gathered information regarding sociodemographic characteristics, HPV vaccination status, and willingness to receive the vaccine. Once the participant completed the survey, the staff of the Outreach Program conducted an educational activity. Study participants completed a pre- and post-test, which included a scale with items related to knowledge about HPV infection, associated malignancies, and the vaccine. To compute the mean knowledge score for each test, the correct responses were summed; the total scores for each test ranged from 0 to 11. Follow-up interviews (3 and 6 months) explored knowledge changes and-in the previously unvaccinated students-vaccine uptake.

RESULTS

A total of forty students answered the questionnaire. A significant difference between the average knowledge before (7.6 ± 2.1) and after the intervention (10.6 ±0.6) (P < .001) was observed. Of the non-vaccinated group, 59.3% reported being interested in receiving the vaccine. By the 3- and 6-month follow-ups, only 2 students had started the vaccine series.

CONCLUSION

Knowledge about HPV and associated malignancies increased significantly. However, few students initiated the vaccine after either of the followups. Future efforts should line up the vaccine promotion and outreach activities with immunization services, making the vaccine available in the communities to be impacted.

Content analysis of digital media coverage of the human papillomavirus vaccine school-entry requirement policy in Puerto Rico

Background

In August 2018, Puerto Rico (PR) became the 4th state or territory in the United States to adopt a human papillomavirus (HPV) vaccine school-entry requirement, for students 11–12 years old. Evidence suggests that the content of media coverage may impact people’s perception of HPV vaccine and their willingness to vaccinate. This study aimed to analyze the content of digital news coverage related to the implementation of the policy in PR.

Methods

A content review was conducted of digital media published from January 2017 through December 2018. The content reviewed was carried out in two steps: 1) creating a matrix to summarize each article’s content about the policy and 2) qualitative analysis using a grounded theory approach.

Results

The search resulted in 34 articles obtained from 17 online local and international news outlets that reported the policy's implementation. Analyses showed that 61% of the news articles did not mention the number of required doses, and 79% discussed the new policy concerning cancer prevention. In 2017, news coverage focused mostly on describing the policy, while 2018 coverage focused on controversies surrounding the implementation. Neutral emergent codes included: 1) Description of the policy; 2) Information about HPV related cancers; and 3) General information about HPV vaccine. Negative emergent codes included: 1) infringement to patient and parental autonomy; 2) Hesitancy from the political sector, and 3) Hesitancy from groups and coalitions. Positive content included: 1) knowledge and acceptance of HPV vaccine for cancer prevention; 2) importance of education and protective sexual behaviors; and 3) new vaccination law proposal.

Conclusions

Most of the media coverage in PR was neutral and included limited information related to the vaccine, HPV, and HPV-related cancers. Neutral and negative themes could influence public concerns regarding the new policy, as well as HPV vaccination rates in PR.

Barriers to Human Papillomavirus Vaccine Uptake Among Racial/Ethnic Minorities: a Systematic Review

BACKGROUND

Human papillomavirus (HPV) is associated with poor health outcomes, including cervical cancer. Racial/ethnic minority populations experience poor health outcomes associated with HPV at higher rates. A vaccine is available to protect against HPV infections and prevent HPV-related sequelae; however, vaccination rates have remained low in the United States (U.S.) population. Thus, there is an urgent need to increase the HPV vaccination rate. Moreover, little is known about barriers to HPV vaccination in racial/ethnic minority groups. This paper highlights the most recent findings on barriers experienced by these groups.

METHODS

The PubMed database was searched on July 30, 2020, for peer-reviewed articles and abstracts that had been published in English from July 2010 to July 2020 and covered racial/ethnic disparities in HPV vaccination.

RESULTS

Similar findings were observed among the articles reviewed. The low HPV vaccination initiation and completion rates among racial/ethnic minority populations were found to be associated with lack of provider recommendations, inadequate knowledge and awareness of HPV and HPV vaccination, medical mistrust, and safety concerns.

CONCLUSIONS

Provider recommendations and accurate distribution of information must be increased and targeted to racial/ethnic minority populations in order to bolster the rate of vaccine uptake. To effectively target these communities, multi-level interventions need to be established. Further, research to understand the barriers that may affect unvaccinated adults in the catch-up age range, including males, may be beneficial, as majority of the previous studies focused on either parents of adolescents or women.

Knowledge and perception of female nursing students about human papillomavirus (HPV), cervical cancer, and attitudes toward HPV vaccination

Objective: The researchers aimed to evaluate the knowledge and perceptions of first-year female nursing students about human papillomavirus (HPV), cervical cancer (CC), and HPV vaccination. Participants: The sample included 690 female nursing students from sampled universities between April and June 2015. Methods: Students were surveyed by using a pretested HPV and CC awareness questionnaire. Results: More than half of the students (65.1%) answered questions incorrectly with a mean HPV knowledge score of 6.085 ± 3.38. The majority of students (82.6%) did not hear HPV vaccine. Only, 2.8% of the students had been vaccinated. A statistically significant relationship was found between HPV knowledge score and hearing about HPV vaccine (U = 28280.500, p = .015), and believing HPV vaccine protectiveness (χ² = 14.153, p = .001). Conclusions: This study highlights the lack of knowledge and low level of awareness about HPV, CC, and HPV vaccination among first-year nursing college students.

Seroprevalence of HPV 6, 11, 16 and 18 and correlates of exposure in unvaccinated women aged 16-64 years in Puerto Rico

Background

To understand risk factors for HPV exposure in Puerto Rican women, we evaluated HPV 6, 11, 16, and 18 serology in women aged living in the San Juan metropolitan area.

Methods

As part of a cross-sectional study, a population-based sample of 524 HPV unvaccinated Hispanic women ages 16–64 years completed face-to-face and computer assisted interviews and provided blood and self-collected anal and cervical specimens. Serology used multiplex virus-like particle based-IgG ELISA and HPV DNA was detected with L1-consensus PCR.

Results

32% and 47% were seropositive to HPV types included in the bivalent (16/18) and quadrivalent (6/11/16/18) vaccines, respectively. Type-specific seroprevalence was HPV6 − 29%, HPV11 − 18%, HPV16 − 23%, and HPV18 − 17%; seroprevalence was high in the youngest age-group (16–19: 26–37%). HPV seropositivity was associated with having ≥ 3 lifetime sexual partners (OR=2.5, 95% CI=1.7–3.9) and detection of anogenital HPV DNA (OR=1.8, 95% CI=1.2–2.6).

Conclusions

The high cumulative exposure of HPV vaccine types 6/11/16/18 in this Hispanic population was influenced by factors related to HPV exposure through sexual behavior. High seroprevalence in the youngest age-group indicates early age of exposure to HPV in Puerto Rico, highlighting the need for HPV vaccination starting prior to age 16.

Prevalence and correlates of cervical HPV infection in a clinic-based sample of HIV-positive Hispanic women

Objectives

Puerto Rico (PR), is the fifth highest jurisdiction of the United States of America (US) with respect to HIV prevalence and the leading in cervical cancer incidence. This cross-sectional study describes the prevalence and correlates of cervical HPV infection among a clinic-based sample of 302 women living with HIV/AIDS in PR.

Methods

Data collection included questionnaires, blood and cervical samples. Multivariable logistic regression models were used to estimate the magnitude of association (adjusted Prevalence odds ratio [aPOR]) between HPV cervical infection and other covariates.

Results

Mean age of participants was 40.3 years (± 10.3 SD). The prevalence of HPV infection was 50.3%; 41.1% for low-risk types and 29.5% for high-risk types. Having ≥ 10 lifetime sexual partners (aPOR = 2.10, 95% CI:1.02–4.29), an abnormal Pap (aPOR = 3.58, 95% CI:1.93–6.62), active genital warts (aPOR = 3.45, 95% CI:1.60–7.42), and CD4 counts ≤ 200 (aPOR = 4.24, 95% CI: 1.67–10.78) were positively associated with any cervical HPV infection. Similar results were observed for HR HPV infection.

Conclusions

A high burden of HPV co-infection exists among women living with HIV/AIDS in this population. Given the high incidence of HIV in PR and the higher risk of cervical cancer among women living with HIV/AIDS, HPV vaccination should be promoted in this population.

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.
