Attitudes Regarding HPV Vaccinations of Children among Mothers with Adolescent Daughters in Korea

Investigating the knowledge and attitude of mothers with teenagers toward human papillomavirus vaccine injection

BACKGROUND

Human papillomavirus (HPV) is a large family of viruses and is considered the most common sexually transmitted infection. One of the effective and cost-effective primary prevention methods are vaccines made against the HPV. Considering the significant prevalence of HPV disease and the importance of its prevention, this study was prepared and compiled with the aim of determining the knowledge and attitude of mothers with teenagers toward the injection of the HPV vaccine and its related factors in order to increase the acceptance of this virus vaccination.

MATERIALS AND METHODS

The current research is a cross-sectional study (descriptive and analytical) that was conducted in the health and treatment centers of Pakdasht city in the year 2021. The sample size was calculated to be 407 people, which consisted of mothers with teenage girls or boys aged 11-16 years. The tools of data collection were information-demographic-medical form, questionnaire measuring knowledge, and attitude of mothers about HPV. Experiment and data analysis were done with SPSS version 26. Strobe checklist was also used to write the text of the article.

RESULT

The average age of mothers was 35.61 (6.11) and the average age of fathers was 41.61 (7.21). Most of the people (49.1%) had one child, and most of the children were girls (57.5%). The average knowledge score was 23.98 ± 3.22, and the average attitude score was 10.04 ± 1.84. The average total score of knowledge and attitude was 34.02 ± 4.12 (at the average level). The results of the Mann-Whitney test indicated that the mean average of knowledge and attitude according to the gender of the child, membership in virtual medical networks, place of residence, income adequacy, history of cervical cancer in the family, history of physical illness in teenagers, and history of genital warts mean (P) < 0.05) were significant. Also, Spearman's test showed that there is a positive and significant correlation between mothers' knowledge and attitude toward the HPV vaccine (R = 0.296), which was statistically significant (P < 0.05).

CONCLUSION

The results of this study indicate that the acceptance of vaccination by mothers can be related to various factors. Therefore, it is expected that by knowing the factors related to the acceptance rate of mothers, we design support programs in line with increasing the acceptance of mothers to carry out adolescent vaccinations.

Human papillomavirus vaccination hesitancy among young girls in Ethiopia: factors and barriers to uptake

Background

Human papillomavirus (HPV) vaccinations protect against HPV infections. The infection might lead to vaginal cancer, vulvar cancer, genital warts, cervical intraepithelial neoplasia lesions, and cervical cancer. This study assessed hesitancy of HPV vaccination, associated factors, and barriers to vaccination among youth girls in Ethiopia.

Methods

An institutional-based cross-sectional study was conducted among female undergraduate students at the University of Gondar, College of Medicine and Health Sciences, between July and August 2022. The data was collected using a self-administered questionnaire. A simple random sampling method was used to recruit participants. The data were entered and analyzed with SPSS version 26. Descriptive statistics were used to describe the participants' demographic characteristics. Logistic regression was performed to identify the significant factors associated with acceptance of the HPV vaccine. A p-value <0.05 was considered statistically significant.

Results

The study included 423 participants with a mean age of 22.5 ± 6.7 years. Only more than one-third (35.2, 95% CI: 27.2-44.1) received the HPV vaccine. Currently, more than one-fourth (27.9, 95% Cl: 21.4-33.8) of participants are hesitant to receive the HPV vaccine. Higher monthly income (AOR = 1.52, 95% CI: 1.08-6.34), good knowledge of the HPV vaccine (AOR = 2.12, 95% CI: 1.12-4.87), and a positive attitude towards the vaccine (AOR = 3.03, 95% CI: 1.63-9.56) were significantly associated with acceptance of HPV vaccination. Safety concerns (63.1%), misinformation (42.8%), and parental concerns (42.3%) about the HPV vaccine were among the top perceived reported barriers to receiving the HPV vaccine.

Conclusion

This result showed that more than a quarter number of youth girls are still hesitant to receive HPV vaccinations. To increase vaccination acceptance, interventions should focus on awareness-raising programs about HPV infection and vaccines and addressing safety and parental concerns.

Willingness of caregivers to have their daughters vaccinated against human papilloma virus and associated factors in Jimma Town, Southwest Ethiopia

Introduction

Human Papillomavirus (HPV) is a widespread sexually transmitted infection and a leading cause of cervical cancer. Although there is a significant HPV prevalence in Ethiopia, yet the uptake of the HPV vaccine remains low. This study aimed to assess the level of caregivers' willingness to vaccinate their daughters against the human papilloma virus and associated factors in Jimma town.

Methods

A community-based cross-sectional study was conducted from June 1-30, 2023. A total of 471 study participants were selected using multi-stage sampling techniques. Data was collected using an interviewer-administered questionnaire. Binary and multiple logistic regression analyses were done to identify associated factors, and the adjusted odds ratio and 95% confidence interval were computed. A value p of <0.05 was used to determine statistical significance.

Results

About 82.4% (95% CI: 79.0-86.0) of caregivers indicated a willingness to have their daughters vaccinated. Having college education or above (AOR:3.31, 95%CI:1.02-10.8), good knowledge of the HPV vaccine (AOR:2.25, 95%CI:1.05-4.85), good knowledge of sexually transmitted infections (STIs) (AOR:2.04, 95%CI: 1.09-3.82), good knowledge of cervical cancer (AOR:2.50, 95%CI:1.31-4.77) and a positive attitude towards the vaccine (AOR:4.03, 95%CI: 2.26-7.22), were associated with willingness.

Discussion

The majority of caregivers were willing to vaccinate their daughters against HPV. Caregivers who had higher education, good knowledge about the HPV vaccine, cervical cancer, and STIs, as well as positive attitudes towards the vaccine, were more likely to be willing to vaccinate. Efforts should be made to educate caregivers about the vaccine, cervical cancer, and STIs while promoting positive attitudes.

Uptake of Human Papilloma Virus Vaccination and Associated Factors Among Female Students Attending Secondary Schools in South West Shoa, Oromia, Ethiopia, 2022

BACKGROUND

Human papillomavirus (HPV) vaccination is one of the key preventative measures for cervical cancer, provided that effective vaccine uptake is employed. However, HPV vaccine uptake is low in settings with limited resources such as low- and middle-income countries.

OBJECTIVES

To assesses the uptake of HPV vaccine and associated factors among female students attending secondary schools in South West Shoa Zone, Oromia, Ethiopia, 2022.

METHODS

A cross-sectional study was conducted in secondary schools of South West Shoa Zone between November 1st to November 30th 2022. A multi-stage sampling technique was employed among 634 female students attending secondary schools. Data were collected by self-administered structured questionnaires, entered into Epi-info version 7.2.2.6, and exported to SPSS version 25 for statistical analysis. Bivariable analyses were considered for Multivariable analysis. Adjusted odds ratio (AOR) along with 95% confidence levels were estimated to assess the strength of the association, and a P value <0.05 was considered to indicate statistical significance.

RESULTS

The proportion of HPV vaccine uptake was 31.65% (95% CI, 25-38). Having adequate knowledge AOR = 8.51 (95% CI = 4.57-15.84), living in rural area AOR = 0.25 (95% CI = 0.15-0.42), having older sibling AOR = 4.07(95% = 2.50-6.63), mother's educational level (Diploma and above) AOR = 4.08 (95% CI = 1.75-9.49), and secondary education AOR = 3.98 (95% CI = 1.87-8.48) were significantly associated with HPV vaccine uptake among female students attending secondary schools in South West Shoa Zone, Oromia, Ethiopia.

CONCLUSIONS

The study revealed that HPV vaccine uptake was very low among female students attending secondary schools in South West Shoa Zone, Oromia, Ethiopia. Adequate knowledge, having older sibling, living in rural area, and having mothers with higher educational level were significantly associated with HPV vaccine uptake. All concerned bodies should work jointly to enhance the uptake of HPV vaccination among female students.

An Integrative Review of the Influence on Human Papillomavirus Vaccination Adherence among Adolescents

To enhance the vaccination rate of adolescents against HPV, understanding their current vaccination intentions and identifying the factors that influence their decision to vaccinate are imperative. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) was used to search for relative literature. Five electronic databases (CINAHL, PubMed, Web of science, Research Information Sharing Service (RISS) and Korea Citation Index (KCI)) were searched from 2007 to 2022, and 19 studies were selected for final review. The Mixed Methods Assessment Tool (MMAT) was used as a critical appraisal tool to evaluate the quality for various types of research designs. This integrative review revealed three themes, including facilitators (personal characteristics and environmental factors), barriers (lack of awareness and knowledge about HPV, concerns about side effects, and the burden of costs), and ways to increase vaccination uptake (knowledge promotion and HPV vaccines coverage by public insurance). To encourage HPV vaccine uptake, it is essential to enhance public knowledge, create compelling advertisements, and ensure that the vaccines are covered by public insurance. Moreover, providing educational programs that emphasize the effectiveness and significance of HPV vaccines to adults who can influence the vaccination decisions of adolescents is vital.

Knowledge and attitude toward human papillomavirus vaccination and associated factors among adolescent school girls in Ambo town, Ethiopia, 2021: A multicenter cross-sectional study

Background and Aims

The human papillomavirus (HPV) vaccination has shown considerable promise in lowering the incidence of cervical cancer. However, there are few studies done on knowledge and attitude toward the HPV vaccine, especially in the local setting. Therefore, this study aimed to assess knowledge and attitudes regarding HPV vaccination and related factors among adolescent girls in Ambo town, Ethiopia, in 2021.

Methods

A cross-sectional study was conducted from May 1 to May 30, 2021, at selected schools in Ambo town among 422 adolescent girls. A structured self-administered questionnaire was used to collect the data. The collected data were coded, and entered into Epi-Info 7.2.2.6 and exported to STATA 16 for analysis. Descriptive statistics were used to compute summary statistics and proportions. Bivariate and multivariate logistic regression analyses were carried out. The adjusted odds ratio (AOR) along with a 95% confidence interval (CI) was computed to ascertain the association.

Results

Current study revealed that 24.9% (95% CI: 20.8-29.0) and 55.6% (95% CI: 50.5-60.4) of respondents had good knowledge and favorable attitude, respectively. The factors like being secondary school students [AOR = 2.01, 95% CI; (1.24, 3.27)], having health workers as a source of information [AOR = 2.13, 95% CI; (1.30, 3.47)], and respondents who have heard about the HPV vaccine at school [AOR = 1.66, 95% CI; (1.02, 2.71)] were significantly associated with respondent's knowledge of HPV vaccine. Moreover, the perceived severity of the diseases [AOR = 2.89, 95% CI; (1.61, 5.21)], and the perceived benefit of the vaccine [AOR = 4.26, 95% CI; (2.43, 7.48)] were factors significantly associated with an attitude of the respondents about the HPV vaccine.

Conclusion

There was low knowledge and unfavorable attitude toward HPV vaccination among the school adolescents in the study area. Several seemingly major deterrents of knowledge and attitude toward the HPV vaccination were identified. Therefore, all parties involved should collaborate to improve female students' knowledge and attitudes toward Human Papilloma Virus vaccination.

HPV pathogenesis, various types of vaccines, safety concern, prophylactic and therapeutic applications to control cervical cancer, and future perspective

Over 98% of cervical cancers (CC) are caused by regular infections with "high risk" genotype of the human papilloma virus (HPV). However, this is not always the causative factor. Therefore, production of HPV vaccinations represents a significant chance to minimize the risk of CC. Phase III studies for a number of preventative HPV vaccines based on L1-virus-like particle (VLPs) have just been completed and the preliminary results are very convincing. However, there are a lot of practical concerns that need to be resolved before the use of these vaccinations. These vaccines were challenged with obvious queries such as protection time, subject receiving vaccines, time of vaccination, and how to include them into ongoing screening programs. Although these vaccines were 90% effective at preventing HPV infection as these offered only modest advantages for the removal of pre-existing infections. New advancements in the creation of therapeutic vaccinations have been explored for further improvement and post-vaccination surveillance. Therapeutic vaccines attempted to boost cell-mediated immunities and these are detrimental to the infected cell as opposed to neutralizing antibodies (different from prophylactic vaccines).

Human Papillomavirus (HPV) Vaccination Intent among Mothers of Adolescent Sons: A National Survey on HPV Knowledge, Attitudes and Beliefs in South Korea

PURPOSE

Human papillomavirus (HPV) is one of the most common sexually transmitted infections affecting both males and females but there is an apparent lack of knowledge and apprehension towards male HPV vaccination South Korea. The purpose of the present study was to examine the associations between knowledge and perceptions of male HPV vaccination and vaccination intent among Korean mothers of adolescent sons.

MATERIALS AND METHODS

We conducted a cross-sectional study using a nationwide online survey. The independent variables were mothers' sociodemographic characteristics, history of HPV diagnosis, general HPV knowledge, HPV vaccine knowledge, and attitudes and beliefs towards male HPV vaccination. The outcome variable was mothers' intent to vaccinate their sons, which was classified into three categories: non-intent, undecided and intend to vaccinate. We performed univariate analysis and multinomial logistic regression analysis.

RESULTS

A total of 906 eligible mothers completed the survey. Mothers received low scores on the HPV-related knowledge scales with low ratings on the scale measuring perceived risk of HPV. Approximately 10% of the mothers intended to vaccinate their sons against HPV, 61.0% were undecided and 1.5% already had their sons vaccinated. According to the multinominal logistic regression analysis, having a daughter in the family, mothers' previous diagnosis with HPV, general HPV knowledge, influence, harm, and risk were significantly associated with being undecided and having intentions to vaccinate their sons (p<0.05).

CONCLUSIONS

Our study revealed that Korean mothers are generally less aware of male HPV vaccination, have low perceived risk of HPV, and remain highly hesitant on vaccinating their sons against HPV. It is therefore important to raise public awareness about male HPV vaccination and alleviate vaccine hesitancy. Such efforts will contribute to improving parents' vaccination intent, increasing vaccine uptake among male adolescents and prevention of HPV-associated diseases.

Knowledge and attitude regarding human papillomavirus vaccine and its associated factors among parents of daughters age between 9-14 years in central Ethiopia, 2021

Background

Human Papillomavirus (HPV) is the most common sexually transmitted disease and the major cause of cervical cancer, which threatened the lives of several women and remains a critical concern in Africa and around the world. Ethiopia initiates the human papillomavirus vaccines on 3 rd December 2018 for the primary time to vaccinate six million girls.

Objective

This study assessed knowledge and attitudes toward the human papillomavirus vaccine among parents of daughters aged between 9 and 14 years in the Central Ethiopia.

Methods

A community-based cross-sectional study was conducted on 619 parents whose daughters were aged between 9 and 14 years old from February 01 to February 30, 2021. A multistage sampling method was employed to select study participants. Data were collected using an interview administered questionnaire adapted from related literature. Descriptive, bivariate, and multivariate binary logistic regression analyses were done by using SPSS v. 20.0.

Results

A total of 619 parents participated in the current study of whom, only 242 (39.1%) and 249 (40.2%) of the respondents were knowledgeable and had a favorable attitude toward the HPV, respectively. Age (AOR 1.98, 95% CI: 1.07, 3.69), place of residence (AOR 3.6, 95% CI: 1.45, 8.92), and wealth status (AOR 1.89, 95% CI: 1.09, 3.26) was independently associated with the knowledge of parents toward the HPV.

Conclusion

Policymakers and other stockholders require more effort to provide a resource to enhance knowledge and attitudes toward the HPV through the mass media and other health education outlets. Keywords: Knowledge, HPV Vaccine, Attitude, Cervical cancer, Central Ethiopia.

Indepth Interviews' on Acceptability and Concerns for Human Papilloma Virus Vaccine Uptake among Mothers of Adolescent Girls in Community Settings in Ibadan, Nigeria

Human papillomavirus (HPV) vaccine offers protection of between 80 and 100% for anogenital warts and 60-80% in reducing the incidence of pre-malignant lesions from cervical cancer. However, uptake remains low in Nigeria among adolescent girls. This study was a qualitative study that assessed mothers' acceptability and concerns regarding uptake of HPV vaccine by their adolescent daughters. In-depth interviews were conducted with 20 mothers of adolescents girls aged 9-15 years. A snowballing sampling technique was adopted to select the mothers within the community. Consent was obtained for the use of audiotapes, which were transcribed verbatim with thematic analysis of data. Mothers were between the ages of 30-49 years and most of them were traders. Almost all of the women have heard about cervical cancer, but their knowledge about cervical cancer and HPV vaccine was low. Despite their low knowledge, most of the mothers accepted that the vaccine is good and was willing for their adolescent daughters to take the HPV vaccine for the prevention of HPV. However, cost of the vaccine, side effects, and potential exposure of their daughters to promiscuity after taking the vaccine for protection were the major concerns expressed by the mothers as regards to HPV vaccine uptake by their daughters. Findings highlight the need for health promotion and education programs about cervical cancer, HPV, and HPV vaccine to increase awareness and knowledge among mothers of adolescent girls. Also, HPV vaccination should be included as part of routine immunization for female adolescents.

Factors Associated with the HPV Vaccination among Korean Americans and Koreans: A Systematic Review

Koreans and Korean Americans (KAs) have limited HPV knowledge and awareness. KAs share a culture with Koreans, and this culture has affected their behavior around HPV. This systematic review aimed to synthesize the factors associated with HPV vaccination among Koreans and KAs. The literature search was done with four databases. The vaccination rate, awareness and knowledge of HPV, and factors associated with vaccination intention were identified. Eighteen articles were selected. Koreans and KAs had low levels of HPV knowledge and awareness. Perceived benefits and seriousness were associated with vaccination intention. Cervical cancer history, beliefs that their daughters need a pap smear test, sexual intercourse experiences, occupation, low education, and income were associated with vaccination intention. This systematic review discovered that HPV vaccination behavior is associated with HPV vaccine awareness, perceived benefits of the vaccine, and the perceived seriousness of HPV infection among Koreans and KAs. Based on the results, we suggest healthcare providers provide a HPV vaccine recommendation by emphasizing the benefits of the vaccination to Koreans and KAs. This study can be the basis for developing interventions to increase HPV vaccination by guiding the target population and variables, as well as the intervention content.

Resources for assessing parents' vaccine hesitancy: a systematic review of the literature

The concept of Vaccine Hesitancy has begun to appear in the scientific landscape, referring to the reluctance of a growing proportion of people to accept the vaccination offer. A variety of factors were identified as being associated with vaccine hesitancy but there was no universal algorithm and currently there aren't any established metrics to assess either the presence or impact of vaccine hesitancy. The aim of this study was to systematically review the published questionnaires evaluating parental vaccine hesitancy, to highlight the differences among these surveys and offer a general overview on this matter. This study offers a deeper perspective on the available questionnaires, helping future researches to identify the most suitable one according to their own aim and study setting.

YouTube as a Source of Information and Education on Hysterectomy

BACKGROUND

Globally, YouTube is one of the most popular websites, and the content is not restricted to entertainment. The purpose of this study was to assess the quality of information in YouTube videos pertaining to hysterectomy.

METHODS

We explored YouTube using the search terms "hysterectomy" and "remove uterus." The videos that appeared were sorted using the filter "sort by view count." Of the initial 100 videos, the top 50 videos for each search term were included for review, as determined by the "relevance" filter based on YouTube's algorithm. After excluding 34 videos for various reasons, 66 were included in the final analysis. Each video rated as "useful" was further analyzed for reliability and completeness of information; a set of pre-determined criteria were modified from a previous study and used to grade the quality of videos.

RESULTS

The top 66 videos on hysterectomy had a total of 4,679,118 views. Based on authorship, the videos were categorized as follows: videos uploaded by patients, 37%; academic videos, 35%; videos uploaded by physicians, 13%; commercial videos, 4%; and videos uploaded by non-physicians, 2%. The type of content was also categorized: 50% of the videos recorded personal experiences, 23% recorded surgical techniques, 21% involved explanations of the surgery, and 4% were commercial videos. The majority of the videos made by patients were negatively biased toward hysterectomy surgery (71.72%), while the majority of those made by academics or physicians were surgical educational videos for doctors, not patients.

CONCLUSION

YouTube is currently not an appropriate source for patients to gain information on hysterectomy. Physicians should be aware of the limitations and provide up-to-date and peer-reviewed content on the website.

Awareness and knowledge of human papillomavirus vaccination and their influential factors among Chinese women: a systematic review

Objectives

To systematically review the knowledge attitudes and the influential factors on human papillomavirus (HPV) vaccination among Chinese women.

Methods

Published studies on knowledge and attitudes of HPV vaccination for preventing cervical cancer among Chinese female population were retrieved using the major Chinese and English databases. Meanwhile, handwork retrieval was also conducted and the references including in the literature were retrieved. The quality of the literature was rigorously evaluated and extracted independently by two researchers and the data were analyzed and described by review manager 5.3 (RevMan5.3) software.

Results

In all, 19 articles including 8 articles in Chinese and 11 in English were chosen. A total of 30,176 participants were included and the sample size ranged from 64 to 6,024. The overall awareness of HPV and HPV vaccine among Chinese women was at a low level. Chinese women generally showed poor knowledge about HPV and HPV vaccine. Acceptance of HPV vaccination among Chinese women was at a high level. Vaccination intentions were influenced by the theory of planned behavior (TPB) and measured by attitudes subjective norms and perceived behavioral control.

Conclusions

The health authorities may evaluate and develop TPB-based interventions to increase HPV vaccination intentions of Chinese women. HPV vaccination programs should focus on carrying out multi-level and targeted health education and developing effective public health strategies after balancing the cost and benefit of HPV vaccine program. Medical staff should play the positive role in promoting the use of HPV vaccines in China. Integration of policy and community perspectives and multi-level interventions are essential to maximize the public health benefits of HPV vaccination.

Awareness and attitude towards human papillomavirus and its vaccine among females with and without daughter(s) who participated in cervical cancer screening in Shenzhen, China

OBJECTIVES

To evaluate the awareness of HPV and HPV vaccine, and willingness to be vaccinated against HPV, among women with and without daughter(s) in Shenzhen, China.

METHODS

Cross-sectional survey in January and June 2015 by means of a self-administered questionnaire to collect information. Multivariate logistic regression was used to explore the factors associated with awareness of HPV and its vaccine and the willingness to be vaccinated.

RESULTS

A total of 9855 women (mean age 37.09 years, SD 7.48) were included in the analysis. Although only 42.3% had heard of HPV and 21.0% of HPV vaccine, 63.3% were willing to be vaccinated. 73.9% of the 5799 women with daughter(s) were willing have their daughter(s) vaccinated. Women with daughter(s) did not have a higher awareness of HPV (43.2% vs. 41.5%, P = 0.109) and HPV vaccine (21.1% vs. 20.9%, P = 0.854) than women without daughter(s), but did tend to be more willing to be vaccinated themselves (66.3% vs. 59.9%, P < 0.001). Women's awareness of HPV and specific knowledge of HPV vaccine were predictors of the willingness to have both themselves and their daughters vaccinated. These associations may be modified by residency status, education and monthly income.

CONCLUSIONS

Although awareness of HPV and HPV vaccine among women in Shenzhen was low, willingness to have themselves and their daughter(s) vaccinated was relatively high, especially among mothers. High awareness of HPV and its vaccine will help improve the acceptability of HPV vaccination according to residency status, education and monthly income.

Clinical nurses' awareness and caring experiences for patients with cervical cancer: A qualitative study

To determine the degree to which nurses are aware of cervical cancer and to describe nurses' experiences of caring for patients with cervical cancer. To promote quality of nursing care of cervical cancer, we need to explore their perceptions and nursing experience in doing cervical-cancer care. This study was a qualitative descriptive design. Interviews were conducted with 14 registered nurses. The interviews were audiotaped, transcribed and analyzed. Content analysis was performed. Fourteen nurses who had been working at wards and cancer education centers were recruited in this study. Nine key themes emerged from three categories such as nurses' awareness of cervical cancer, awareness of cervical cancer patient and caring experience. Nurses expressed fear of cervical cancer and helplessness in the face of a life-threatening prognosis. Nurses stated that they might have prejudice about cervical cancer, since it is caused by a sexually transmitted disease. They also recalled that patients with cervical cancer were more sensitive and demanding. Our findings provide a comprehensive and in-depth perspective in understanding the experience of caring for cervical cancer patients. Clinical nurses showed complex emotional reactions to cervical cancer, and expressed prejudice against the sex life of cervical-cancer patients. More education is required to ensure that clinical nurses can provide a nurse-led intervention with patients by managing nurses' fear, prejudice, and the care burden.

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.

Burden of Human papillomavirus (HPV)-related disease and potential impact of HPV vaccines in the Republic of Korea

Background

We aimed to review the burden and the potential impact of human papillomavirus (HPV) vaccines on HPV-related diseases in the Republic of Korea and to discuss cervical cancer prevention practices in this country.

Methods

Cancer burden statistics were retrieved from GLOBOCAN-2018 and Statistics Korea. HPV disease burden was assessed via systematic review. Vaccine types relative contribution (RC) was estimated using data from an international project using formalin-fixed paraffin-embedded specimens.

Results

Despite a downtrend in cervical cancer in recent years, Korean rates remain high. In contrast, oropharyngeal cancer incidence has gradually increased and other anogenital cancers remain rare.

In Korea, HPV prevalence in general population is around 20%. In cervical cancer, RC of HPVs 16/18 (74.0%) increased to 92.0% when including HPVs 31/33/45/52/58. Limited information was available for other HPV-related cancer sites.

Regarding prevention, since the inclusion of the HPV vaccine into the National Immunization Program, almost half (49%) of the target cohort in 2016 had received the first dose of vaccine. Further, percentage of women screened with pap has increased from 41.1%-2009 to 53.0%-2016.

Conclusions

HPV-related disease burden in Korea is significant. Results suggest that the combination of effective and high coverage HPV vaccination and screening programmes could substantially impact on HPV-related disease in Korea.

•

HPV-related disease burden (cancer and genital warts) in Korea is significant.

•

HPV16 is the most frequent genotype, causing itself more than 60% of HPV-related cancers.

•

HPV vaccine types 16/18/31/33/45/52/58/6/11 cause 92.0% of cervical cancers.

•

HPV vaccines could significantly impact on the HPV-related disease burden.

Acceptability of two- versus three-dose human papillomavirus vaccination schedule among providers and mothers of adolescent girls: a mixed-methods study in five countries

PURPOSE

The World Health Organization revised its human papillomavirus (HPV) vaccination recommendations to include a two (2-) dose schedule for girls aged ≤ 15 years. We investigated acceptability of 2- versus 3-dose schedule among adolescent vaccination providers and mothers of adolescent girls in five countries.

METHODS

Adolescent vaccination providers (N = 151) and mothers of adolescent girls aged 9-14 years (N = 118) were recruited from Argentina, Malaysia, South Africa, South Korea, and Spain. We assessed providers' preference for a 2- versus 3-dose HPV vaccination schedule via quantitative surveys. Mothers' attitudes towards a 2-dose schedule were assessed through focus group discussions.

RESULTS

Most adolescent providers preferred a 2- over a 3-dose HPV vaccination schedule (overall: 74%), with preference ranging from 45.2% (South Africa) to 90.0% (South Korea). Lower cost, fewer clinic visits, and higher series completion were commonly cited reasons for 2-dose preference among providers and mothers. Safety and efficacy concerns were commonly cited barriers to accepting a 2-dose HPV vaccination schedule among providers and mothers. Mothers generally accepted the reduced schedule, however requested further information from a trusted source.

CONCLUSIONS

Adolescent vaccination providers and mothers preferred the 2-dose over 3-dose HPV vaccination schedule. Acceptability of a 2-dose HPV vaccination could be improved with additional information to providers and mothers on HPV vaccination safety and efficacy.

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.
