Factors Associated with HPV Vaccination among Cambodian American Teenagers

Racial, Ethnic, and Gender Differences in the Timing of Initiating the HPV Vaccine in the United States: the Case of Southeast Asian Americans

Despite the availability of the human papillomavirus (HPV) vaccine, non-Latinx (NL) Southeast Asian Americans have the highest incidence of HPV-associated cervical cancer in the US. Little is known about NL-Southeast Asian Americans' HPV vaccination coverage due to being categorized under the "Asian American" monolith. Therefore, this study uses restricted data from the 2011-2018 National Health and Nutrition Examination Survey (NHANES) to disaggregate NL-Southeast Asian Americans and compare this population's age-specific probabilities of initiating HPV vaccinations to two Asian American subgroups (NL-East Asian and NL-South Asian Americans) and NL-White, NL-Black, and Latinx Americans. Multinomial logistic regression models examine the differences in the timing of initiating the HPV vaccine series, late (ages 13-26) or never, relative to on-time vaccination (by age 12). NL-Southeast Asian Americans are significantly more likely to never vaccinate and to vaccinate late than NL-White, NL-Black, and Latinx Americans, relative to on-time vaccination. NL-Southeast Asian American boys/men are significantly more likely to never initiate the HPV vaccine than Latinx boys/men, relative to on-time vaccination. NL-Southeast Asian American girls/women are significantly more likely to never vaccinate and vaccinate late than NL-White, NL-Black, and Latinx girls/women, relative to on-time vaccination. There are significant gender differences in uptake among all racial and ethnic groups, except among NL-Southeast and NL-East Asian Americans. Disaggregated data on NL-Southeast Asian Americans helps scholars and public health officials uncover health disparities and improve health interventions. Targeted HPV vaccine promotion and services for this population are needed to mitigate current and future health disparities and promote health equity.

An analysis of the knowledge of adults aged between 18 and 45 on HPV along with their attitudes and beliefs about HPV vaccine: the Cyprus case

BACKGROUND

The aim of this research is to analyze knowledge of adults between 18 and 45 years of age and living in the Northern Cyprus about Human Papilloma Virus (HPV) along with their attitudes and beliefs towards HPV vaccine.

MATERIALS AND METHODS

The research, which was planned as a descriptive and cross-sectional, was executed on the web. The research was completed with 1108 women and men adults between 18 and 45 years of age, living in the Northern Cyprus and volunteered to participate in the study.

RESULTS

51.90% of the adults participating in the study were found to be women, 8.84% had a Sexually transmitted disease (STD) before and 63.27% of the individuals who had a sexually transmitted disease before also had had HPV and they knew it, 77.55% had undergone a treatment for their disease, 59.18% were found to be actively infected with HPV. Statistically significant and positive correlations were determined between the overall scores of the participants from the Human Papillomavirus Knowledge Questionnaire (HPV-KQ) and their scores in the perceived severity, perceived benefits and perceived susceptibility sub-dimensions of the Health Belief Model Scale for Human Papilloma Virus and Its Vaccination (HBMS-HPVV) (p < 0.05). There was a statistically significant and negative correlation between HPV-KQ scores, questions on Current HPV Vaccination Program and the perceived barriers sub-dimension of the HBMS-HPVV whereas there was a statistically significant and positive correlation between the HPV-KQ scores, questions on Current HPV Vaccination Program and the perceived benefits and perceived susceptibility sub-dimensions of the HBMS-HPVV (p < 0.05).

CONCLUSIONS

It has emerged that the participants do not have enough information about HPV, they do not know the ways and symptoms of protection from HPV, they do not have enough information about early diagnosis and screening, and they know very little about the HPV vaccine. Health policies should be developed to increase the awareness of individuals about HPV, to increase education and to provide free vaccines.

Acceptance of Human Papillomavirus Vaccination and Associated Factors among Girls in Arba Minch Town, Southern Ethiopia, 2020

Background

Cervical cancer is Ethiopia's second biggest cause of cancer-related death among women. The introduction of human papilloma virus (HPV) vaccination is expected to have a significant impact on the burden of cervical cancer. In Ethiopia, particularly in our study area, little is known regarding girls' acceptance of HPV vaccination. Therefore, this study has assessed the acceptance of HPV vaccination and associated factors among girls in Arba Minch town, southern Ethiopia.

Methods

A school-based cross-sectional study was conducted on January 1, 2020. Based on convenience, Arba Minch town was purposefully selected. Stratification was done to stratify private and public schools, then simple random sampling to select sample schools from each, and finally, a proportional allocation of sample size to each school. The determinants and independent variables that influence the acceptance of the human papillomavirus vaccination were determined using a multivariable logistic regression model.

Results

This study's overall acceptance rate for study participants was 50.4% (95% CI) (45.9-55.2). Girls' age (AOR = 2.93, 95% CI (1.57_5.47), P value 0.001), mothers' educational level (secondary and more than secondary, AOR = 2.40, 95% CI (1.01_5.73), P value 0.048, and 3.64, 95% CI (1.61_8.25), P value 0.002, respectively), positive attitude (AOR = 5.22, 95% CI (2.96_9.19), Pvalue ≤ 0.001), good knowledge (AOR = 2.49, 95% CI (1.19_5.24), P value 0.001), and receiving childhood immunization (AOR = 14.85, 95% CI (8.58_25.72), Pvalue ≤ 0.001) were factors associated with girls' acceptance of the human papillomavirus vaccination. Conclusions and Recommendation. Only half of the study participants accepted HPV vaccination. Therefore, Arba Minch town health institutions should better boost the acceptance of HPV vaccination by improving the knowledge and attitudes of girls. Factors associated with girls' acceptance of HPV vaccination were age, mothers' educational status, positive attitude, knowledge of HPV vaccination, and receiving childhood immunization.

A systematic review of human papillomavirus vaccination among US adolescents

The human papillomavirus (HPV) causes many anogenital and oral cancers affecting young adults in the United States. Vaccination during adolescence can prevent HPV-associated cancers, but vaccine uptake among adolescents is low and influenced by factors serving as barriers and facilitators to HPV vaccination. In this systematic review, we synthesized research using the socioecological framework model to examine individual-level, relationship-level, community-level, and societal-level factors that influence HPV vaccine initiation and completion among US adolescents. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to guide the methodology for this review. An electronic search was conducted in January 2020 using PubMed, Cumulative Index of Nursing and Allied Health Literature, ProQuest Central, Scopus, and American Psychological Association PsycInfo databases. The Joanna Briggs Institute tools were used to assess the quality for the 57 studies included in this review. The most consistent influences of HPV vaccination included age at vaccination, awareness, and knowledge about HPV vaccination, socioeconomic status, insurance status, race/ethnicity, and preventative care behaviors at the individual level. Provider recommendation, familial/peer support of vaccination, and parental health behaviors were influences at the relationship level. Although fewer findings elucidated community-level and societal-level influences, high-poverty areas, high-risk communities with large proportions of racial/ethnic minority groups, healthcare facilities servicing children, and combined health policies appear to serve as facilitators of HPV initiation and completion. Findings from this review can inform culturally relevant and age-specific interventions and multi-level policies aiming to improve HPV vaccination coverage in the United States.

Awareness, knowledge, social norms, and vaccination intentions among Khmer mother-daughter pairs

Cervical cancer is caused by human papillomavirus (HPV) infection, which can be prevented by vaccination. Mothers play an important role in promoting vaccination and health education. However, Cambodian American mothers reported to have challenges to play a role as primary health educators due to lack of health knowledge and language and cultural gaps. Therefore, this study aims to understand the Cambodian American daughters' and mothers' awareness, knowledge and social norms of HPV vaccination and their health communication and vaccination decision-making. We conducted a pilot randomized clinical trial to promote HPV vaccination. In this study, we have only reported findings from baseline data examining individual, interpersonal and social determinants of HPV vaccination behavior among 19 dyads of Cambodian American mothers and daughters. Both mothers and daughters demonstrated low levels of awareness and knowledge. A significant relationship was found between the daughters' HPV vaccine decisions and their perception of their mothers' intention on HPV vaccination for them. Culturally and linguistically appropriate communication strategies such as storytelling or visual presentation approaches may be more effective than the current practice of using information-based written materials to promote HPV vaccination and health education among Cambodian Americans.

Knowledge of Cervical Cancer, Human Papilloma Virus (HPV) and HPV Vaccination Among Women in Northeast China

This study aimed to research the understanding and knowledge of cervical cancer, human papilloma virus (HPV), and HPV vaccination, and the acceptance of HPV vaccination, among a population of women in northeastern China. A cross-sectional survey was carried out by questionnaire to investigate knowledge of cervical cancer, HPV, and HPV vaccination. The 230 female participants were native residents of northeastern China, and their ages ranged between 18 and 65 years. Questionnaires were randomly acquired by the respondents from online and paper questionnaire distribution. The questionnaire included questions on three major aspects to record people's perceptions of cervical cancer, HPV, and vaccines. Of the sample of 230 women surveyed, 80.9% had heard of cervical cancer, but understanding was only 15.7%; 38.3% knew about HPV; 20% knew about HPV vaccine; 39.6% agreed to receive HPV vaccination, and the remainder were mainly concerned about its safety and effectiveness. Data analysis showed that age, family income, and whether there was experience of screening all influenced knowledge of cervical cancer, but this was not statistically significant. The level of education had no obvious effect on the degree of knowledge about cervical cancer; however, with an improvement in education, women's awareness of HPV vaccine improved significantly (p < 0.05). Women who have received cervical cancer screening had significantly greater knowledge about cervical cancer and HPV than those with no screening (p < 0.05). Women in northeastern China have little knowledge of cervical cancer, HPV, and HPV vaccine, lack disease knowledge, and hold a skeptical attitude about HPV vaccination. Medical institutions are the main channel providing information to these women.

A systematic review of practice-, provider-, and patient-level determinants impacting Asian-Americans' human papillomavirus vaccine intention and uptake

INTRODUCTION

Asian-Americans have been documented to have low human papillomavirus (HPV) vaccine initiation and completion. No research has attempted to examine underlying mechanisms of HPV vaccine uptake disparities among Asian-Americans. Using the P3 (practice, provider, and patient) model, this study aimed to identify practice-, provider-, and patient-level determinants of Asian-Americans' HPV vaccine intention and uptake.

METHODS

We conducted a systematic review of published literature regarding practice-, provider- and patient-level determinants of vaccine intention (e.g., intention, willingness, or acceptability) and uptake (e.g., initiation or completion). Eligible studies were those presenting empirical/original data, focusing on Asian populations in the U.S., including outcomes related to HPV vaccine intention and uptake, and analyzing data on factors associated with these outcomes separately for Asian groups.

RESULTS

Twenty-six studies (19 quantitative and 7 qualitative studies) were included in the review. Most commonly studied subgroups were Koreans (n = 9), Chinese (n = 6), and Cambodians (n = 5). Studies showed varied prevalence across subgroups (intention: 23.4%-72%; initiation: 14%-67%; completion: 9%-63%). Only 3 studies included measurements of practice-level determinants (language services, insurance policy). Twelve studies measured provider-level determinants (most commonly documented: HPV vaccine recommendation). All studies measured patient-level determinants (most commonly documented: HPV and HPV vaccine knowledge, perceived safety, perceived susceptibility, and perceived relationship between HPV vaccine and sexual activity).

CONCLUSIONS

Existing research on determinants of HPV vaccine intention and uptake among Asian-Americans currently lacks measurements of practice-level constructs and perspectives of clinic staff and providers, which are needed to guide system-level interventions and provider training. Data regarding patient-level determinants suggest that interventions for Asian-American populations can focus on providing educational information in culturally-appropriate manners, leveraging familial influences, and attending to access-related or cultural beliefs about HPV vaccine. Interventions should take into account varied vaccine intention and uptake prevalence in different Asian subgroups.

Factors Associated with Initiation of HPV Vaccination Among Young Women and Girls in Urban and Suburban New Orleans

Vaccination coverage against human papilloma virus (HPV) in the United States remains low. This study aimed to identify factors associated with initiation of HPV vaccination among young women and girls in New Orleans, Louisiana. The study was conducted in Pediatrics and Obstetrics & Gynecology clinics in New Orleans between 2014 and 2017. Surveys were administered to women ages 18 through 26, and guardians of girls ages 12 through 17. Demographics, health history, sources of medical information, knowledge of HPV and HPV vaccination, opinions on vaccination, expected support for vaccination, and systems-level barriers were assessed. Participants self-reported discussion of the vaccine with a healthcare provider, and whether they or their child had been vaccinated. Participants were predominantly black and low-income. Among young adults, 61/121 (50%) had received any doses of the HPV vaccine; 71/94 (75%) of girls had received it (p < 0.01). In both groups, knowledge of the HPV vaccine, believing the vaccine was available from their usual healthcare provider, and having discussed the vaccine with their provider were associated with increased odds of vaccination. Among young adults, additional factors associated with vaccination were younger age, distance from a healthcare center, knowledge of HPV, and expectation of support from parents. Among guardians, holding negative views on vaccination was associated with decreased odds of vaccination. Discussion of the vaccine with a healthcare provider was the factor most strongly associated with initiation of HPV vaccination in both groups. The results provided actionable items to increase HPV vaccination uptake in these populations.

Health system factors influencing uptake of Human Papilloma Virus (HPV) vaccine among adolescent girls 9-15 years in Mbale District, Uganda

Background

Globally, cervical cancer is the fourth most common cancer in women with more than 85% of the burden in developing countries. In Uganda, cervical cancer has shown an increase of 1.8% per annum over the last 20 years. The availability of the Human Papillomavirus (HPV) vaccine presents an opportunity to prevent cervical cancer. Understanding how the health system influences uptake of the vaccine is critical to improve it. This study aimed to assess how the health systems is influencing uptake of HPV vaccine so as to inform policy for vaccine implementation and uptake in Mbale district, Eastern Uganda.

Methods

We conducted a cross sectional study of 407 respondents, selected from 56 villages. Six key informant interviews were conducted with District Health Officials involved in implementation of the HPV vaccine. Quantitative data was analyzed using Stata V.13. Prevalence ratios with their confidence intervals were reported. Qualitative data was audio recorded, transcribed verbatim and analyzed using MAXQDA V.12, using the six steps of thematic analysis developed by Braun and Clarke.

Results

Fifty six (14%) of 407 adolescents self-reported vaccine uptake. 182 (52.3%) of 348 reported lack of awareness about the HPV vaccine as the major reason for not having received it. Receiving vaccines from outreach clinics (p = 0.02), having many options from which to receive the vaccine (p = 0.02), getting an explanation on possible side-effects (p = 0.024), and receiving the vaccine alongside other services (p = 0.024) were positively associated with uptake.

Key informants reported inconsistency in vaccine supply, inadequate training on HPV vaccine, and the lack of a clear target for HPV vaccine coverage as the factors that contribute to low uptake.

Conclusion

We recommend training of health workers to provide adequate information on HPV vaccine, raising awareness of the vaccine in markets, schools, and radio talk shows, and communicating the target to health workers.

Uptake of the HPV vaccine was lower than the Ministry of Health target of 80%. We recommend training of health workers to clearly provide adequate information on HPV vaccine, increasing awareness about the vaccine to the adolescents and increasing access for girls in and out of school.

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.

HPV vaccine acceptance among African-American mothers and their daughters: an inquiry grounded in culture

BACKGROUND

Much of the research on African-Americans' HPV vaccine acceptance has largely focused on racial/ethnic differences related to cognitive, socio-economical, and structural factors that contribute to differences in HPV vaccine acceptance and completion. A growing body of literature suggest that cultural factors, such as mistrust of healthcare providers (HCPs) and the healthcare system, religion, and social norms related to appropriate sexual behaviors, also plays a prominent role in their HPV vaccine acceptance. However, these studies were limited in their use of theoretical approaches necessary to conceptualize and operationalize culture.

OBJECTIVE

To explore the influence of culture on African-American mothers' and daughters' HPV vaccine acceptance using the PEN-3, a culturally-centered conceptual framework.

METHODS

Grounded theory techniques were used to explore cultural factors that influenced the acceptance of the HPV vaccine among African-American mothers (n = 28) and their daughters (n = 34).

RESULTS

Positive attitudes towards vaccination stemmed from beliefs that the HPV vaccine has cancer prevention benefits and that vaccinations in general protected against infectious diseases. Negative attitudes stemmed from beliefs that the HPV vaccine was too new, not effective, daughters were too young, and that vaccines were not a one-size-fits-all intervention. Majority of mothers and daughters indicated that their religious doctrine did not impede their HPV vaccination decisions. For a few mothers, religious beliefs could not be separated from their HPV vaccination decisions and ultimately deterred HPV vaccine acceptance. HCP recommendations were valued however mothers were often dissatisfied with the detail of information communicated. Support networks provided both positive and negative types of social support to mothers and daughters. The media highlighted the cancer prevention benefits of the HPV vaccine and unintentionally communicated negative information of the HPV vaccine, which deterred HPV vaccine acceptance.

CONCLUSION

Study findings can inform the development of culturally appropriate interventions that advances the evidence on cervical cancer prevention.

HPV VACCINE ADHERENCE AMONG ADOLESCENTS: INTEGRATIVE REVIEW

ABSTRACT Objective: to identify what factors are connected to adolescent adherence to the vaccination against Human Papillomavirus. Method: integrative developed using the following data base: Medical Literature Analysis and Retrieval System Online and Web of Science, Cumulative Index to Nursing and Allied Health Literature, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Latin-American and Caribbean Literature in Health Sciences), and Base de dados de Enfermagem (Nursing Database); using the descriptors and keywords: Papillomaviridae, immunization, vaccines. The final sample had 31 original articles. Result: Vaccine adherence predictors were identified as: knowledge about virus infection risk, vaccination and its benefits; cervical cancer and genital warts prevention; sexual activity; being over 14 years old; mothers’ intention to adhere to vaccination; mother-child communication about sexually transmitted infections, contraception and condoms; vaccination offered in school; recommendation by teachers and health professionals; vaccine safety and effectiveness. Conclusion: Evidence points towards the necessity to redesign the presentation strategy of the vaccine, because despite the cultural differences among the countries where the studies were carried out, it is noticeable that society shelters adolescents aged from 10 to 14 years old, considering it early for sexual initiation and presenting difficulties to broach sexuality-related topics with children.

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

OBJECTIVE

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

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

The Uptake of Human Papillomavirus Vaccination and Its Associated Factors Among Adolescents: A Systematic Review

Background: The purpose of this review was to explore the uptake of the human papillomavirus (HPV) vaccination, its associated factors, and the facilitators of and barriers to HPV vaccination among adolescents. Methods: A comprehensive literature search was conducted through 5 electronic databases, including PubMed, CINAHL, Cochrane Library, Medline, and PsycInfo from January 2006 to March 2015 for studies examining the uptake, awareness, knowledge, acceptability, and intention of adolescents with regard to HPV vaccination. Results: Twenty-eight studies were identified and included. The HPV vaccination uptake rate (at least 1 dose) varied significantly among countries, ranging from 2.4% to 94.4%. Scotland achieved the highest uptake of all the studies included in this review, while Hong Kong had the lowest, at 2.4% to 9.1%. This review also showed that adolescents had limited awareness and knowledge of HPV infections and vaccines, even 10 years after the vaccine had become available. Conclusions: It is recommended that barriers to the uptake of the vaccine should be addressed, and that school-based sexual health education of HPV infection and vaccine promotion should be reinforced.

Human Papillomavirus: A Qualitative Study of Korean American Female College Students' Attitudes Toward Vaccination

BACKGROUND

Human papillomavirus (HPV) vaccines have the potential to reduce Korean American women's high burden of cervical cancer, but information is limited about their awareness of HPV and its vaccine.
.

OBJECTIVES

This study aimed to explore Korean American female college students' awareness of and attitudes toward HPV vaccination.
.

METHODS

A qualitative descriptive study was used. Five focus group interviews were conducted with 20 Korean American female college students aged 18-26 years from Massachusetts. Data were analyzed using inductive content analysis.
.

FINDINGS

Major themes were awareness, misunderstandings, attitudes, social influences, and cultural influence. A critical need exists to develop and implement culturally and linguistically appropriate HPV prevention education programs to promote HPV vaccination in this population.
