Knowledge of cervix cancer, human papilloma virus (HPV) and HPV vaccination at the moment of introduction of the vaccine in women in Belgium

Vaccine Hesitancy among European Parents-Psychological and Social Factors Influencing the Decision to Vaccinate against HPV: A Systematic Review and Meta-Analysis

BACKGROUND

Due to low adherence to HPV vaccination programs, the European region struggles with vaccination rates lower than 30% among the targeted population. The present report investigated various socio-demographic and psychological factors influencing European parents' hesitancy towards vaccinating their children.

METHODS

As of September 2023, four databases were searched. After applying inclusion criteria, all articles comparing psychological and socio-demographic factors in parents who vaccinate or do not vaccinate their children were included.

RESULTS

Twenty-five primary publications met the criteria, totaling 385,460 responders, of which 311,803 want to or have already vaccinated their child, and 73,555 do not wish to do so. Immigrant and employment status, religion, age of parents and the child's gender seemed to influence their decision to vaccinate their child. Previous experience with vaccines, perceived safety and efficacy and the mother's previous abnormal CCS results also impacted their decision. The caregivers' education, gender, civil status, number of children, family history of neoplasia or mother's CCS attendance did not influence their hesitancy to vaccine.

CONCLUSION

Multiple demographic, social, economic and psychological barriers involved in the parents' hesitancy to vaccinate their children against the HPV virus were highlighted. Specific at-risk categories that need to be targeted with information, education and vaccination campaigns were identified.

Awareness Levels of the Link Between Oropharyngeal Cancer and HPV Infection Among Spanish Women: a Hospital-Based Cross-sectional Study

Several observational studies have demonstrated the increased awareness of human papillomavirus (HPV) as an etiological factor of oropharyngeal cancers (OPCs). The incidence of OPCs has increased in recent times, particularly among younger women, and the efficacy of the HPV vaccine in preventing these cancers has gained attention among the medical community. The aim of this study was to explore the health literacy of Spanish adult women regarding factors associated with HPV and its link to OPCs, as well as their awareness of the HPV vaccination. A survey was distributed to 508 women, and 409 (70.5%) were considered as valid participants. The majority of the participants were Caucasian (97.8%) with a mean age of 44.1 ± 11.6. Out of all the participants, only 48.9% women identified HPV as a possible etiology of OPC. The most common sources of information regarding this association were the internet (31.3%), video media (28.9%), and healthcare professionals (28.9%), whereas 16.1% of the participants reported that they had obtained information from three or more sources. The average number of correct answers in the 16-item survey which was used to determine the participants' knowledge of HPV-related diseases was 8.7 ± 4.2, and the average number of correct answers in the 6-item survey regarding the usefulness of the HPV vaccination was 3.3 ± 1.6. According to bivariate models, the variables associated with a poorer level of awareness were related mainly to education (p < 0.001), sexual behavior (p < 0.001), and employment status (p < 0.001). This study contributes toward the discovery of the previously unforeseen psychosocial burden of HPV and its related diseases among Spanish women.

Women's Knowledge of Cervical Cancer: A cross-sectional study in Al Buraimi Governorate, Oman

Objectives

This study aimed to assess knowledge of cervical cancer and its prevention among Omani women aged 20-65 years.

Methods

This cross-sectional study took place across eight primary healthcare institutions in Al Buraimi Governorate, Oman, between November 2018 and February 2019. It was carried out on the basis of a predesigned, validated and self-administered questionnaire containing 55 questions.

Results

Data from 791 completed questionnaires were included in the final analysis, which represents a response rate of 79.1%. The results indicated that 86.7% of surveyed women had previously heard of cervical cancer and 13.0% expected this disease to affect them in the future. The results also showed that women were less aware of the association between the human papillomavirus (HPV) and cervical cancer (24.7%). The participants considered the HPV infection and initiation of sexual intercourse below 17 years of age as the lowest risks associated with cervical cancer. Moreover, 63.8% of the participants were unaware of the availability of a vaccination 'against HPV-related cervical cancer' and many respondents were unaware of a Pap test. Those women aged over 30 years, married and with a high level of education were more likely to be aware of cervical cancer.

Conclusion

Generally, there was inadequate knowledge and awareness of cervical cancer among women aged 20-65 years. Young women aged 20-30 years showed relatively lesser knowledge of cervical cancer as compared to their older counterparts. Thus, concerted efforts are needed to promote such awareness among women in Oman.

Cervical cancer screening using HPV tests on self-samples: attitudes and preferences of women participating in the VALHUDES study

Background

Interventions to reach women who do not participate regularly in screening may reduce the risk of cervical cancer. Self-collection of a vaginal specimen has been shown to increase participation. The relative clinical accuracy of human papillomavirus (HPV) testing on first-void urine (with Colli-Pee) and on vaginal self-samples versus on cervical clinician-collected samples is being investigated in the VALHUDES trial. The current study assesses attitudes and experiences regarding self-sampling among women enrolled in VALHUDES.

Methods

Questionnaires from 515 women (age 25–64 years [N = 498]; < 25 [N = 10], age ≥ 65 [N = 3], enrolled between December 2017 - January 2020) referred to colposcopy because of previous cervical abnormalities and enrolled in VALHUDES (NCT03064087) were analysed.

Results

Of the 515 participants, nearly all women confirmed that self-sampling may help in reaching under-screened women (93%). Nevertheless, 44% of the participants stated before starting collection that a clinician-collected sample is more effective than a self-collected sample. After self-sampling, the large majority of women (> 95%) declared that instructions for self-collection were clear, that collection was easy, and that they were confident about having performed the procedure correctly, for both urine and vaginal collection. However, a proportion of women found self-sampling unpleasant (9.5% [49/515] for urine collection; 18.6% [96/515] and 15.5% [80/515] for vaginal sampling with cotton swabs or plastic brushes, respectively). For their next screening round, 57% would prefer self-sampling whereas 41% opted for collection by a clinician. Among women preferring self-sampling, 53% would choose for urine collection, 38% for vaginal self-collection and 9% had no preference. Age did not modify preferences.

Conclusion

We conclude that both urine and vaginal self-sampling are well accepted by women, with a preference for urine sampling. Although the large majority of women are confident in their ability to perform self-sampling, four to five over ten women preferred specimen collection by a clinician.

Trial registration

The study VALHUDES was registered in ClinicalTrials.gov (identifier: NCT03064087).

Determinants of Human Papillomavirus Vaccine Uptake by Adult Women Attending Cervical Cancer Screening in 9 European Countries

INTRODUCTION

Human papillomavirus-vaccinated cohorts, irrespective of age, will likely reduce their subsequent screening requirements, thus opening opportunities for global cost reduction and program sustainability. The determinants of uptake and completion of a 3-dose human papillomavirus vaccination program by adult women in a European context were estimated.

STUDY DESIGN

This was an intervention study.

SETTING/PARTICIPANTS

Study participants were women aged 25-45 years, attending opportunistic or population-based cervical cancer screening in Belgium, Denmark, Finland, France, Germany, Slovenia, Spain, Sweden, and the United Kingdom between April 2016 and May 2018.

INTERVENTION

Study participants completed a questionnaire on awareness and attitudes on adult female human papillomavirus vaccination and were invited to receive free human papillomavirus vaccination.

MAIN OUTCOME MEASURES

Main outcome measures were acceptance, uptake, and completion of vaccination schedule. Determinants of vaccine uptake were explored using multilevel logistic models in 2019.

RESULTS

Among 3,646 participants, 2,748 (range by country=50%-96%) accepted vaccination, and 2,151 (range=30%-93%) received the full vaccination course. The factors associated with higher vaccine acceptance were previous awareness of adult female (OR=1.22, 95% CI=1.00, 1.48) and male (OR=1.59, 95% CI=1.28, 1.97) vaccination. Women in stable relationships (OR=0.56, 95% CI=0.45, 0.69) or with higher educational level (OR=0.76, 95% CI=0.63, 0.93) were more likely to refuse vaccination. Recruitment by postal invitation versus personal invitation from a healthcare professional resulted in lower vaccine acceptance (OR=0.13, 95% CI=0.02, 0.76). Vaccination coverage of >70% of adolescent girls in national public programs was of borderline significance in predicting human papillomavirus vaccine uptake (OR=3.23, 95% CI=0.95, 10.97). The main reasons for vaccine refusal were vaccine safety concerns (range=30%-59%) and the need for more information on human papillomavirus vaccines (range=1%-72%). No safety issues were experienced by vaccinated women.

CONCLUSIONS

Acceptance and schedule completion were largely dependent on recruitment method, achieved coverage of national vaccination programs, and personal relationship status. Knowledge of benefits and safety reassurance may be critical to expanding vaccination target ages. Study results suggest that there are no major opinion barriers in adult women to human papillomavirus vaccination, especially when vaccination is offered face to face in healthcare settings.

Development and Validation of Questionnaire to Assess Knowledge about Cervical Cancer among Women Aged 20 to 65 years in Oman

OBJECTIVE

This study aimed to develop and validate a questionnaire to assess awareness of cervical cancer, its risk factors, and methods of prevention among Arabic-speaking women aged 20 years and over.

METHODS

The study took place at primary healthcare institutions, Al Buraimi Governorate, Oman, between November 2018 to February 2019. In phase I, seventy items concerning cervical cancer and its prevention were generated through a literature review. In phase 2, the questionnaire was validated through calculating the content validity index (CVI) for both item level (I-CVI) and the scale level (S-CVI), in this phase a shortened English questionnaire of 55 items was formed, then rigorously translated to the Arabic language in phase III. The questionnaire was tested for reliability in two stages: A pilot and a large field test in phase IV.

RESULTS

A total of 55 out of 70 items formed the final version of the questionnaire. The final instrument had an S-CVI/Ave of 0.92. The questionnaire called the Knowledge in Cervical Cancer and Prevention Methods 55-items (KCCPM-55). The Cronbach alpha coefficient was 0.940 for the whole questionnaire, and ranged between 0.57 to 0.93 for each of the domains. Test-retest reliability was examined in a subsample of the total participants sample (r = 0.769, p < 0.001).

CONCLUSION

The KCCPM-55 has been successfully developed in the Arabic language and found to be a valid and reliable instrument for assessing the level of knowledge about cervical cancer and prevention methods among women aged 20 to 65 years in Oman.

A nationwide post-marketing survey of knowledge, attitude and practice toward human papillomavirus vaccine in general population: Implications for vaccine roll-out in mainland China

BACKGROUND

Human papillomavirus (HPV) vaccine has been increasingly discussed in mainland China since its first approval in 2016. To date, nearly all studies assessing HPV vaccine perceptions and attitudes were implemented during pre-licensure period. Therefore, the nationwide post-marketing survey was conducted to update knowledge, attitudes and practice on HPV vaccine among general population in mainland China.

METHODS

Participants aged 18-45 years living in mainland China were recruited in April 2019 by multi-stage non-randomized sampling. Sociodemographic factors, HPV and HPV vaccine related awareness, knowledge, attitudes, vaccine uptake and potential obstacles were assessed in questionnaires. Bivariate analysis and multivariate regression were used to identify disparity among subgroups with different sociodemographic characteristics.

RESULTS

4,000 women (32.1 ± 7.81y) and 1,000 men (31.8 ± 7.96y) were included in final analysis. Less than one third of participants had heard of HPV (female: 31%; male: 22%) and HPV vaccine (female: 34%; male: 23%). Knowledge score was also unfavorable on HPV (female: 3 out of 13; male: 1.8 out of 13) and HPV vaccine (female: 3 out of 6; male: 2 out of 5). Only 3% females had been vaccinated three years after HPV licensure in China, although willingness to get vaccinated among those unvaccinated were high (mean willingness score ± SD: female: 3.3 ± 0.97; male: 3.0 ± 0.98). Industry of employment and household income were the major factors related to awareness and knowledge of vaccine, whereas HPV and HPV vaccine awareness were key influential factors for willingness. The main obstacles of vaccination were safety concerns, lack of knowledge, and high price of HPV vaccines.

CONCLUSIONS

Findings highlight a lack of vaccine awareness, knowledge, and poor uptake in mainland China and underscore the necessity of health education campaigns. The identified priority groups, contents to be delivered and practical obstacles could furthermore provide insight into health education to reduce disparities and accelerate HPV vaccine roll-out in China.

Knowledge, Attitudes, and Practices Regarding Cervical Cancer Screening among HIV-infected Women at Srinagarind Hospital: A Cross-Sectional Study

Introduction:

In recent years, the lives of HIV-infected patients in Thailand have improved significantly due to continuous advances in treatment. However, the rate of cancer related to HIV infection (especially cervical cancer) is likely to increase. Although the World Health Organization (WHO) recommends Papanicolaou testing in all HIV-infected women, few of these patients receive this kind of screening in Thailand. Therefore, we conducted this study to evaluate the knowledge, attitudes, and practices of these patients with regard to cervical cancer screening.

Materials and Methods:

This cross-sectional study was conducted in HIV-infected women aged 18-65 years from April to November 2019 via a self-administered cervical cancer screening questionnaire, which consisted of four parts: demographic data, knowledge, attitudes, and practices.

Results:

Three hundred HIV-infected women were recruited. Most of the participants had good attitudes toward screening and practiced adequate screening (75.3% and 71.3%, respectively). However, only 62 participants (20.7%) demonstrated adequate knowledge. The crucial factors that were associated with adequate screening practice were age 40-49 years-old (AOR =3.26, 95%CI=1.02-10.37), CD4 cell count (AOR = 3.41, 95%CI = 1.29-8.99), having been advised about cervical cancer screening (AOR= 6.23, 95%CI 1.84-21.07), and attitude toward screening (AOR= 5.7, 95%CI = 2.23-14.55). The major reasons for not undergoing screening were embarrassment (41.86%), lack of symptoms (41.86%), fear of the results (36.04%), and fear of pain (36.04%).

Conclusion:

The reasons for inadequate testing were disregard and misconceptions about the procedure. To prevent invasive cervical lesions in HIV-infected women, health care providers should inform these patients about the importance of regular cervical cancer screening.

HPV vaccine acceptance is high among adults in Mexico, particularly in people living with HIV

OBJECTIVE

To measure HPV vaccine acceptance in diverse Mexican adult popula-tions, taking into account HIV status.

MATERIALS AND METHODS

A total of 1 329 men and women, with and without HIV, participated in one of three intervention studies, offering HPV vaccination, carried out in the states of Morelos, Tlaxcala and Mexico City; either the bivalent (Morelos n=103, Tlaxcala n=127) or quadrivalent HPV-vaccine (Mexico City n=1 099) was offered.

RESULTS

HPV vaccine was accepted by 80.3% of participants; acceptance was higher in people living with HIV than those without (84.4 vs. 78%, p=0.004). Women had greater HPV infection knowledge (p<0.0001) than men and slightly higher (p=0.4) vaccine acceptance. The main reason for vaccine non-acceptance among HIV-positive participants was their doctor recommended they not get vaccinated.

CONCLUSIONS

Acceptance of HPV-vaccine was high in men and women regardless of HIV status. Even higher rates of acceptability may be achieved by educating healthcare providers to recommend HPV vaccine to their patients.

HPV vaccination in a context of public mistrust and uncertainty: a systematic literature review of determinants of HPV vaccine hesitancy in Europe

Europe is increasingly described as the region in the world with the least confidence in vaccination, and particularly in the safety of vaccines. The aim of this systematic literature review was to gather and summarise all peer-reviewed and grey literature published about determinants of Human Papillomavirus (HPV) vaccine hesitancy in Europe. Ten thematic categories were identified across the 103 articles which were included in the review. Participants from European studies most commonly reported issues with the quantity and quality of information available about HPV vaccination; followed by concerns about potential side effects of the vaccine; and mistrust of health authorities, healthcare workers, and new vaccines. Comparative analyses indicated that confidence determinants differed by country and population groups. This evidence supports the need to develop context-specific interventions to improve confidence in HPV vaccination and design community engagement strategies aiming to build public trust.

Factors Influencing Knowledge and Practice Regarding Cervical Cancer and Pap smear Testing among Omani Women

Background:

Knowledge of cervical cancer and performance of Pap smear testing are influenced by several sociodemographic factors. This study aimed to describe the effect of relevant variables on knowledge and compliance with guidelines in Oman.

Methods:

In this cross-sectional survey, participants were divided into three groups: patients who attended Outpatient Gynecology Department, female medical staff and university graduate students.

Results:

There were 204 outpatients, 133 staff, and 157 students. Adequate knowledge among was seen in 38.7%, 35.3%, and 7.6%, respectively. Knowledge of cervical cancer and Pap smear was significantly lower among outpatients with secondary education, while those with high level of income were more likely to have adequate cancer knowledge. Uptake of Pap smear was significantly greater among outpatients aged ≥ 30 years, with high income and a positive history of cancer.

Conclusion:

Culturally tailored interventions that focus on improving cancer risk knowledge are needed to maximize screening uptake for cervical cancer.

Knowledge about Human Papillomavirus and Cervical Cancer: Predictors of HPV Vaccination among Dental Students

Background: The objective of this study is to determine the influence of dental students’ knowledge and attitude regarding human papillomavirus infection of cervical cancer on willingness to pay for vaccination. Basic research design: A convenience sampling method was used. The minimal sample size of 136 was calculated using the Raosoft calculator with a 5 % margin of error and 95% confidence level. Participants: The study population were all final year dental students from the School of Dentistry. Methods: A self-administered questionnaire was used to measure knowledge levels and attitudes regarding human papillomavirus vaccination. Contingent valuation was conducted for willingness to pay for vaccination. Main outcome measures: The Center for Disease Control and Prevention has stated that human papillomavirus are associated with oropharynx cancer and the American Dental Association insist on expanding public awareness of the oncogenic potential of some HPV infections. Thus, as future dental practitioners, dental students should be aware of human papillomavirus and their links with cancer and the benefits of vaccination. Results: Knowledge on HPV and cervical cancer did not impact on attitudes towards vaccines. However, significant correlation existed between knowledge and willingness to pay for vaccination. Conclusions: Dental students’ knowledge on HPV and cervical cancer has no influence on their attitude towards HPV vaccines. However, their willingness to pay for HPV vaccination is influenced by their knowledge of cervical cancer and HPV vaccination.

Human Papillomavirus vaccination in general practice in France, three years after the implementation of a targeted vaccine recommendation based on age and sexual history

In France, vaccination against human papilloma virus (HPV) was recommended in 2007 for all 14-year-old girls as well as "catch-up" vaccination for girls between 15-23 y of age either before or within one year of becoming sexually active. We evaluated the vaccine coverage according to the eligibility for vaccination in a sample of young girls aged 14 to 23 years, who were seen in general practices. A survey was proposed to 706 general practitioners (GPs) and carried out from July to September 2010. GPs, also called "family doctor," are physicians whose practice is not restricted to a specific field of medicine but instead covers a variety of medical problems in patients of all ages. Each participating GP included, retrospectively, the last female patient aged 14-17 y and the last female patient aged 18-23 y whom he had seen. A questionnaire collected information regarding the GP and the patients' characteristics. The vaccine coverage was determined according to the eligibility for vaccination, i.e. the coverage among younger women (14-17) and among those sexually active in the second age range (18-23). Sexual activity status was assessed by GP, according to information stated in the medical record. The 363 participating physicians (response rate 51.4%) included 712 patients (357 in the 14- to 17-year-old group and 355 in the 15- to 23-year-old group) in their responses. The rate of the vaccination coverage in the 14- to 17-year-old group was 55%. Among the girls in the 18- to 23-year-old group, 126 were eligible, and their vaccination coverage rate was 82%. The evaluation of the eligibility by the GPs was incorrect in 36% of the cases. Of the 712 patients, 6% of the girls had been vaccinated without a need for the vaccination, and 26% of the girls had not been vaccinated, although they needed to be vaccinated. Regarding the vaccine uptake, vaccination at the age of 14 was not as effective as vaccinating the older population for which vaccination was indicated as a catch-up program, based on sexual history. However, in more than one-third of the older population, difficulties remained regarding the determination of eligibility, according to the sexual history of the patient.

Knowledge, Attitude and Practice Concerning Human Papilloma Virus Infection and its Health Effects among Rural Women, Karnataka, South India

BACKGROUND

Cervical cancer is one of the commonest cancers among women all over the world. The association of cervical cancer with human papilloma virus (HPV) is well established. Knowledge about the causal relationship between HPV and cervical cancer is important to make appropriate, evidence-based health care choices. In this context we conducted a community based study among women about the knowledge, attitude and practice about HPV infections and their health effects.

MATERIALS AND METHODS

A cross sectional interview based house to house survey was conducted with a validated data collection tool covering sociodemographic factors, knowledge, attitude and practice about HPV and its health effects, among 1020 women from a rural village, Perdoor, in Udupi district, Karnataka, India in 2013-14.

RESULTS

The mean age of participants was 38.9 years (SD=12.6). Study participants showed a high literacy rate (85.7%). Only 2.4% of sexually exposed women had undergone Pap smear testing. Partners of 4.4%women had undergone circumcision and they belonged to the Muslim community. Male condom usage was reported by 26 women (2.6%). However, none of the participants had heard of HPV and its health effects.

CONCLUSIONS

This community based study found complete ignorance about HPV among rural South Indian women in spite of a high literacy level.

Effect of a group educational intervention on rural Chinese women's knowledge and attitudes about human papillomavirus (HPV) and HPV vaccines

Background

Statistics regarding HPV prevalence and cervical cancer rates in rural China are high, however, low levels of HPV awareness and HPV-related knowledge pose a great challenge for cervical cancer control.

Methods

The authors conducted an educational intervention study, which was embedded in a cervical cancer screening project in Yangcheng county, Shanxi Province, China from October to December, 2011 and was designed to assess the short-term effectiveness of a hospital-based, brief, HPV-focused session on rural Chinese women’s knowledge and attitudes. Student’s t-test was used when comparing quantitative variables. Chi-squared test or Fisher’s exact tests was used when comparing qualitative variables.

Results

We found that following the intervention, significant increases were detected in awareness regarding HPV (5.9 % vs. 59 %, p < 0.001) and cervical cancer (63.0 % vs. 89.2 %, p < 0.001). Changes were also observed regarding women’s intention to vaccinate themselves (82.0 % vs. 89.0 %, p = 0.001) and their daughters (82.9 % vs. 88.0 %, p = 0.011), although the impact was more modest compared with the impact on change of awareness. Among women who were aware of HPV, 60.3 % knew that cervical cancer is related to HPV, while only 5.0 % knew the relationship between HPV and genital warts after the educational intervention.

Conclusions

Educational campaigns, particularly those targeting women with limited education and poor access to public media or other educational channels are needed to improve knowledge regarding HPV in the general population.

Knowledge about cervical cancer early warning signs and symptoms, risk factors and vaccination among students at a medical school in Al-Ahsa, Kingdom of Saudi Arabia

BACKGROUND

Cervical cancer is the second most common cancer among females and also the most preventable. In the literature there is abundant evidence that awareness regarding cervical cancer and its prevention is low in the developing countries. Medical students are the future health professionals and can play an important role in increasing awareness among the general population. To assess the knowledge regarding symptoms, risk factors and prevention of cervical carcinoma among medical students in th Kingdom of Saudi Arabia, the present study was planned.

MATERIALS AND METHODS

This cross-sectional study was conducted using a self-administered questionnaire with students at the College of Medicine, King Faisal University, Al-Ahsa, KSA, from December 2012 to May 2013.

RESULTS

The responses of 188 students (males 111, females 77) in their second, third, fourth, and fifth years were recorded and used in the data analysis. The majority of the students were not aware of the early warning signs, symptoms and risk factors. On average, only 43.7% males and 56% of females were aware about the early signs and symptoms whereas 51.4% males and 57.8% females had knowledge about the risk factors of cervical cancers. Some 55% males and 46.8% females were unable to select the correct answer regarding human papilloma virus (HPV) infection as the cause of cervical cancer. Majority of the students (67%) were not aware about the availability of vaccine against HPV.

CONCLUSIONS

Lack of knowledge regarding early signs and symptoms, risk factors and prevention of cervical cancer was observed in the present study.

National HPV immunisation programme: knowledge and acceptance of mothers attending an obstetrics clinic at a teaching hospital, Kuala Lumpur

BACKGROUND

Introduction of the HPV vaccine is a forefront primary prevention method in reducing the incidence of carcinogenic human papillomavirus (HPV) and cervical cancer. The Malaysia government has implemented the National HPV immunisation programme since 2010, supplying HPV vaccine free to targeted 13 year olds. This study aimed to explore the level of knowledge among mothers on cervical cancer, HPV, HPV vaccine and National HPV (NHPV) immunisation programme since its' implementation. It also assessed acceptance of mothers towards HPV vaccine being administered to their daughter, son or themselves.

MATERIALS AND METHODS

A cross sectional study was conducted on 155 respondents using self-administered questionnaires; conducted in December 2012 at the Obstetrics and Gynaecology Clinic in a teaching hospital in Kuala Lumpur. Respondents were selected using a multistage sampling technique.

RESULTS

A response rate of 100% was obtained. Overall, 51.0% of mothers had good knowledge, with 55% having good knowledge of cervical cancer, 54.2% for both HPV and the National HPV immunisation programme and 51.0% for the HPV vaccine. Regression analyses showed that ethnicity was associated with knowledge on cervical cancer (p=0.003) while education was associated with knowledge on HPV (p=0.049). Three factors are associated with knowledge of the National HPV immunisation programme; ethnicity (p=0.017), mothers' education (p=0.0005) and number of children (p=0.020). The acceptance of HPV vaccine to be administered among daughter was the highest at 87.1%, followed by for mothers themselves at 73.5%, and the least is for sons 62.6%.

CONCLUSIONS

This study found that the overall level of knowledge was moderate. Adequate information on cervical cancer, HPV, HPV vaccination and the National HPV immunisation programme should be provided to mothers in order to increase acceptance of the HPV vaccine which can reduce the disease burden in the future.

Awareness and knowledge about human papillomavirus infection and vaccination among women in UAE

BACKGROUND

Cervical cancer is the second commonest female cancer worldwide. The 50-55 cases of cervical cancer are reported annually in the UAE. There is a scarcity of data from Middle Eastern region regarding knowledge and attitude of women towards HPV infection, cervical cancer prevention and HPV vaccine. The aim of our study was to assess the knowledge of women regarding HPV infection and vaccine in UAE.

MATERIALS AND METHODS

A cross-sectional survey of 640 women aged 18-50 years was conducted in Al-Ain district in UAE using convenience sampling. Women with previous diagnosis of cervical cancer, non- residents of UAE, younger than 18 or older than 50 years of age and those unable to speak Arabic or English were excluded from the study. Logistic regression analysis was performed to assess the association of HPV knowledge with independent factors like age, education etc.

RESULTS

Only 29% of our sampled women have ever heard of HPV infection. Only 15.3% women recognized it as STI. Only about 22% women have also heard of the HPV vaccine. Three quarter of the women in our study thought that cervical cancer can be prevented. About 28% recognized vaccine as a preventive measure against cervical cancer. Age (AOR 1.049, 95%CI 1.02-1.08) and husband's level of education were found to be significant (p value 0.015) after adjusting for women's age.

CONCLUSIONS

The knowledge of HPV infection and vaccine is low in the UAE. Few women recognized HPV as sexually transmitted infection. Increasing age and husband's education are associated with better knowledge of HPV infection.

What do women with gynecologic cancer know about HPV and their individual disease? A pilot study

Background

The vaccinations against human papilloma virus (HPV) are highly effective in preventing persistent infection. The level of knowledge about HPV and the consequences of an infection with this virus are low in the general population and in patients who suffer from HPV-associated diseases. We aimed to compare the level of knowledge about HPV and about the women’s individual malignant disease between women with and without HPV-associated gynecologic cancer as well as the knowledge about individual malignant diseases.

Methods

In a pilot study, 51 women with HPV-related cancer (cervical cancer: n = 30; vulvar or vaginal cancer: n = 21) and 60 women with non-HPV associated gynecologic malignancies (ovarian cancer: n = 30; endometrial cancer, n = 30) were included. They answered a questionnaire including questions about personal medical history, risk factors for cancer development, and HPV.

Results

The general level of knowledge of the term “HPV” was low (29.7%, 33/111) and it was similar in patients with HPV-related and non-HPV-associated cancer (18/60, 30.0% vs. 15/51, 29.4%, respectively; p = 1.000). When asked about their disease, 80% (24/30) of women with ovarian cancer correctly named their diagnosis, followed by women with cervical cancer (73.3%, 22/30), endometrial cancer (70%, 21/30) and vaginal or vulvar cancer (42.9%, 9/21; p = 0.008).

Conclusion

The level of knowledge about HPV and the malignant diseases the patient suffered from was low. This applied even to patients with HPV associated malignancies.

Vaccine knowledge in students in Paris, France, and surrounding regions

INTRODUCTION

In France, young adults are legally freed from parental authority at the age of 18 years and are, thus, responsible for their own vaccine record. This young adult population is more frequently exposed to vaccine-preventable infectious diseases.

OBJECTIVE

To determine the factors associated with students' knowledge of the interval between two antitetanus boosters and their report of having up-to-date vaccinations.

METHODS

In April 2009, a survey was conducted involving a random sample of students between 18 and 25 years of age eating lunch at university dining facilities in Paris and its suburbs (Ile de France).

RESULTS

Among the 677 students approached, 583 agreed to participate. Only 207 (36%) of respondents knew the recommended dosing interval between two doses of tetanus vaccine booster (10 years). The majority of students (69%) reported having up-to-date vaccinations. Declaring having up-to-date vaccinations was significantly associated with having a general practitioner (OR 3.03 [95% CI 1.69 to 5.55]). Health care students were significantly more likely to know the decennial interval between two antitetanus boosters (OR 2 [95% CI 1.28 to 3.25]). Most of responding students (n=519 [89%]) believed that vaccines were very useful.

CONCLUSIONS

An overall lack of knowledge of vaccines was observed among this student population. Health care providers, such as GPs and university medical practice staff, who interact with these young individuals have an essential role to promote better vaccination coverage in this population.

The impact of ethnicity on awareness and knowledge of and attitudes towards the human papillomavirus and vaccine among adult women

OBJECTIVE

To determine whether ethnicity affects awareness, knowledge, and attitudes regarding the human papillomavirus (HPV) and the HPV vaccine.

METHODS

English speaking women (n = 172) aged 18 and older were recruited from an outpatient gynaecology clinic to complete a self-administered cross-sectional questionnaire that gathered information about (1) virus awareness and knowledge, (2) vaccine awareness and knowledge, (3) attitudes towards the vaccine and (4) participant demographics. Subjects received a virus knowledge score (0 to 6), a vaccine knowledge score (0 to 10) and an attitudes score (8 to 40), with a higher score indicating more positive attitudes towards the vaccine.

RESULTS

Virus and vaccine awareness was significantly higher in Caucasian respondents than in non-Caucasian respondents: 93% versus 69% (P < 0.001) and 94% versus 64%, (P < 0.001), respectively. In a multivariate logistic regression model, the Caucasian ethnic group, higher education status, and greater number of years in Canada each emerged as independent predictors of vaccine awareness. Both virus and vaccine knowledge scores were significantly higher in Caucasian than non-Caucasian women: 4.6 versus 3.89 (P = 0.001) and 7.2 versus 6.4, (P = 0.042), respectively. Caucasian women had significantly higher (more positive) attitudes towards the vaccine than non-Caucasians (31.4 vs. 29.2, P = 0.021). Higher HPV vaccine knowledge was positively associated with an interest in vaccination (r(2) = 0.26, P < 0.01) and a more positive vaccine attitudes score (r(2) = 0.40, P < 0.001).

CONCLUSION

Virus and vaccine awareness were both higher in Caucasian women than in non-Caucasian women. Improving HPV vaccination knowledge has the potential to improve attitudes and vaccine uptake.

Acceptance of human papillomavirus (HPV) vaccination among young women in a country with a high prevalence of HPV infection

Cervical cancer is the second most common cancer among women in Argentina and the mortality has remained unchanged for the last 30 years. The 2011 national implementation of human papillomavirus (HPV) vaccination will be a key component of future cervical cancer prevention. Vaccination of young adult women is not included in the program, although these women could also benefit from the vaccine, especially in underserved areas with a high prevalence of HPV. However, research on acceptance of HPV vaccination within this group is scarce. The aim of this study was to investigate acceptance of HPV vaccination, the correlation between acceptance and cost, as well as other factors and perceptions of HPV vaccination among young adult women in Argentina. In total, 174 young women aged 18-30 years were included in this quantitative cross-sectional hospital-based study in a low resource area of the Mendoza Province, conducted through structured questionnaire-based interviews. Multinomial logistic regression models were used to investigate correlates of acceptance. Acceptance of HPV vaccination was high if it was free (95%) and even if it was not (75%). A significant positive association was found between acceptance and belief in vaccine safety (p=0.01) and between acceptance and not being a welfare recipient (p=0.00). Nearly half the participants incorrectly believed that they would be fully protected against cervical cancer after vaccination. Our findings suggest that acceptance of HPV vaccination is high among young women in a high-risk, relatively underserved area, even if vaccination is not free. Extensive misconceptions about the vaccine, however, highlight the need for further education about HPV vaccination.

Knowledge about HPV, relation between HPV and cervix cancer and acceptance of HPV vaccine in women in eastern region of Turkey

Objective

The aim of this study is to determine the knowledge of the women living in the eastern region of Turkey about human papillomavirus (HPV) and cervix cancer and their approaches to HPV vaccine.

Methods

The questionnaire forms were distributed to 1,052 patients who applied to the Gynecology Department of Elazig Training and Research Hospital. The subjects were recruited from the general gynecology outpatient clinic of the hospital. The patients from sexually transmitted disease and oncology outpatient clinics were not included in the study. The information about 945 women who completely filled in the questionnaire form was included into the study. The questions set forth in the questionnaire form consisting of 20 questions were prepared by taking the studies previously performed as model.

Results

Ninety-five percent of the women were married and 83.5% were housewives (unemployed). Thirteen percent of the women were illiterate, only 12% were graduated from university. Seventy-four percent of the women did not hear about HPV, 78.4% did not know about HPV vaccine, 63% did not know about the fact that some viruses cause cancer, and 83% did not know about the relation between HPV and cervix cancer. According to the multivariate analysis, free-of-charge vaccination, vaccinated relatives or friends, graduation from university and being under the age of 25 predict to accept the vaccine for themselves.

Conclusion

The young population and the women who graduated from university seem to be more well-informed about HPV and more sensitive about being vaccinated. In addition, free vaccination will ensure the expansion of the vaccine.

Awareness and attitude towards human papillomavirus (HPV) vaccine among medical students in a premier medical school in India

BACKGROUND

As preventing cancer with the help of a vaccine is a comparatively new concept, awareness and education about it will have important implication in the implementation of this strategy.

MATERIALS AND METHODS

Present explorative questionnaire based survey included 618 MBBS students for final analysis.

RESULTS

Majority of participants (89.6%) were well aware of the preventable nature of cervical cancer. Most of them (89.2%) knew that necessary factor responsible for cervical cancer is infection with high risk HPV. Awareness regarding the availability of vaccine against cervical cancer was 75.6%. Females had a better awareness regarding availability of vaccine, target population for vaccination and about the catch up program. Overall acceptance of HPV vaccine among the population studied was 67.8%. Medical teaching had a definitive impact on the understanding of this important public health issue. Females seemed to be more ready to accept the vaccine and recommend it to others. For our study population the most common source of information was medical school teaching. Majority of participants agreed that the most important obstacle in implementation of HPV vaccination program in our country is inadequate information and 86.2% wanted to be educated by experts in this regard.

CONCLUSION

HPV vaccine for primary prevention of cervical cancer is a relatively new concept. Health professional will be able to play a pivotal role in popularizing this strategy.

Inuit women's attitudes and experiences towards cervical cancer and prevention strategies in Nunavik, Quebec

OBJECTIVES

To describe the attitudes about and experiences with cervical cancer, Pap smear screenings and the HPV vaccine among a sample of Inuit women from Nunavik, Quebec, Canada. We also evaluated demographic and social predictors of maternal interest in HPV vaccination.

STUDY DESIGN

A mixed method design was used with a cross-sectional survey and focus group interviews.

METHODS

Women were recruited through convenience sampling at 2 recruitment sites in Nunavik from March 2008 to June 2009. Differences in women's responses by age, education, and marital status were assessed. Unconditional logistic regression was used to determine predictors of women's interest in HPV vaccination for their children.

RESULTS

Questionnaires were completed by 175 women aged 18-63, and of these women a total of 6 women aged 31-55 participated in 2 focus groups. Almost half the survey participants had heard of cervical cancer. Women often reported feelings of embarrassment and pain during the Pap smear and older women were more likely to feel embarrassed than younger women. Only 27% of women had heard of the HPV vaccine, and 72% of these women were interested in vaccinating their child for HPV. No statistically significant predictors of maternal interest in HPV vaccination were found.

CONCLUSIONS

Our findings indicate that health service planners and providers in Nunavik should be aware of potential barriers to Pap smear attendance, especially in the older age groups. Given the low awareness of cervical cancer, the Pap smear and the HPV vaccine, education on cervical cancer and prevention strategies may be beneficial.

Human papillomavirus (HPV) vaccine acceptance and perceived effectiveness, and HPV infection concern among young New Zealand university students

Two-hundred undergraduate students completed an anonymous questionnaire after viewing a human papillomavirus (HPV) vaccine television commercial. Eight-four percent of participants would accept a free HPV vaccine, whereas 47% were unconcerned about future personal HPV infection risk. Males were less likely to accept a free HPV vaccine and to be concerned about future personal HPV infection risk. Perceived HPV vaccine effectiveness was significantly greater among participants who had previously heard of the vaccine and who knew that HPV is sexually transmitted. More education on the role of sexual behavioural characteristics of both males and females in HPV transmission is necessary to promote awareness and concern of personal HPV infection risk and acceptance of HPV vaccination.

Examining future adolescent human papillomavirus vaccine uptake, with and without a school mandate

PURPOSE

To develop a model of adolescent (HPV) human papillomavirus vaccine utilization that explored future HPV vaccination rates, with and without a school mandate, for the vaccine at middle school entry.

METHODS

A dynamic, population-based, compartmental model was developed that estimated over a 50-year time horizon HPV vaccine uptake among female adolescents living in the United States. The model incorporated data on parental attitudes about this vaccine and adolescent health care utilization levels.

RESULTS

Without a mandate, our model predicted that 70% coverage, a lower threshold value used in many previous modeling studies of HPV vaccination, would not be achieved until a mean of 23 years after vaccine availability. Maximal coverage of 79% was achieved after 50 years. With a school mandate in place, utilization increased substantially, with 70% vaccination coverage achieved by year 8 and maximal vaccination coverage, 90%, achieved by year 43.

CONCLUSIONS

Our results suggest that vaccine utilization is likely to be low for several years, though strong school mandates might improve HPV vaccine uptake. These results affect the interpretation of previous modeling studies that estimated the potential clinical effects of HPV vaccination under assumptions of very high vaccine utilization rates.

Knowledge of human papillomavirus infection and its prevention among adolescents and parents in the greater Milan area, Northern Italy

Background

In order to be widely accepted by users, the implementation of a new health intervention requires them to be adequately informed about its clinical importance, benefits and risks. The aim of this study was to provide data on the knowledge of Italian adolescents and parents concerning human papillomavirus (HPV) infection and its prevention in order to allow the development of adequate training programmes.

Methods

Between 2 May and 15 June 2008, we made a cross-sectional survey of 863 high school students and 2,331 parents of middle and high school students using two anonymously completed questionnaires covering the knowledge of HPV infection and related diseases, and attitudes to vaccinations. The approached schools were a convenience sample of the schools of the greater Milan area, Northern Italy.

Results

More mothers than fathers were aware that HPV infection could concern their children (58% vs 53%; p = 0.004) and were favourable towards vaccinating their children against HPV (68% vs 65%; p = 0.03); among the students, more females than males were aware that HPV infection could concern themselves (45% vs 26%; p < 0.001) and would undergo vaccination against HPV (68% vs 40%; p < 0.001). The parents' propensity to vaccinate their children against HPV was significantly associated with professing the Catholic religion (odds ratio - OR = 0.61, 95% confidence interval - CI 0.46-0.82, being atheist), the gender of the offspring (OR = 1.88, 95% CI 1.53-2.30, having at least one daughter), a propensity to vaccinations in general (OR = 23.1, 95% CI 13.7-38.8), a knowledge that HPV vaccine is aimed at preventing cervical cancer (OR = 2.31, 95% CI 1.69-3.16), and an awareness that HPV could affect their own children (OR = 3.52, 95% CI 2.89-4.29). The students who were aware that HPV infection could affect themselves were more in favour of to HPV vaccination, regardless of whether they were male (OR = 5.73, 95% CI 2.85-11.5) or female (OR = 2.39, 95% CI 1.66-3.46).

Conclusions

Both students and parents seem to underestimate the likelihood of HPV infection, and this is associated with a lower propensity for vaccination. This is an important indication for future training programmes concerning HPV prevention designed to increase the acceptance of HPV vaccine in families.

Knowledge and awareness about cervical cancer and its prevention amongst interns and nursing staff in Tertiary Care Hospitals in Karachi, Pakistan

Background and Objective

Cervical cancer is one of the leading causes of morbidity and mortality amongst the gynecological cancers worldwide, especially in developing countries. It is imperative for at least health professionals in developing countries like Pakistan to have a sound knowledge about the disease. This study was carried out to assess the knowledge and awareness about cervical cancer and its prevention amongst health professionals in tertiary care hospitals in Karachi, Pakistan.

Methods and Design

A cross-sectional, interview based survey was conducted in June, 2009. Sample of 400 was divided between the three tertiary care centers. Convenience sampling was applied as no definitive data was available regarding the number of registered interns and nurses at each center.

Results

Of all the interviews conducted, 1.8% did not know cervical cancer as a disease. Only 23.3% of the respondents were aware that cervical cancer is the most common cause of gynecological cancers and 26% knew it is second in rank in mortality. Seventy-eight percent were aware that infection is the most common cause of cervical cancer, of these 62% said that virus is the cause and 61% of the respondents knew that the virus is Human Papilloma Virus (HPV). Majority recognized that it is sexually transmitted but only a minority (41%) knew that it can be detected by PCR. Only 26% of the study population was aware of one or more risk factors. Thirty seven percent recognized Pap smear as a screening test. In total only 37 out of 400 respondents were aware of the HPV vaccine.

Conclusion

This study serves to highlight that the majority of working health professionals are not adequately equipped with knowledge concerning cervical cancer. Continuing Medical Education program should be started at the hospital level along with conferences to spread knowledge about this disease.

A systematic review of measures used in studies of human papillomavirus (HPV) vaccine acceptability

BACKGROUND

The recent proliferation of studies describing factors associated with HPV vaccine acceptability could inform health care providers in improving vaccine coverage and support future research. This review examined measures of HPV and HPV-vaccine knowledge, attitudes, beliefs and acceptability, described psychometric characteristics, and provided recommendations about their use.

METHODS

A systematic search of Medline, CINAHL, PsychoInfo, and ERIC through May 2008 for English language reports of quantitative data from parents, young adults or adolescents yielded 79 studies.

RESULTS

The majority of studies were cross-sectional surveys (87%), self-administered (67%), conducted before prophylactic vaccines were publicly available (67%) and utilized convenience samples (65%). Most measured knowledge (80%), general attitudes about HPV vaccination (40%), and willingness to vaccinate one's daughter (26%). Two-thirds did not report reliability or validity of measures. The majority did not specify a theoretical framework.

CONCLUSIONS

Use of a theoretical framework, consistent labeling of constructs, more rigorous validation of measures, and testing of measures in more diverse samples are needed to yield measurement instruments that will produce findings to guide practitioners in developing successful community and clinical interventions.

High HPV vaccine acceptance despite low awareness among Swedish upper secondary school students

OBJECTIVE

To investigate knowledge of human papillomavirus (HPV) and attitudes to HPV vaccination and condom use among Swedish first year upper secondary school students.

METHODS

Classroom questionnaire filled in by 608 students from a strategic sample of seven upper secondary schools in Sweden.

RESULTS

Only 13.5% (n = 82) of the students had heard about HPV and 6% (n = 35) were aware of HPV vaccination. As many as 84% (n = 508) would like to be vaccinated against HPV. The high cost of vaccination was the greatest obstacle (total group 37%, n = 227); among girls the second major hindrance was the fear of needles (19%, n = 65). Before considering an HPV vaccination 73% (n = 443) wanted more information and 36% (n = 220) would like to receive such information from the school nurse. The students considered it less likely that they would use a condom when having intercourse with a new partner if they were vaccinated than if they were not (p < 0.001).

CONCLUSION

Despite intensive marketing directed at potential vaccine consumers, knowledge of HPV and of HPV vaccines was very low among first year upper secondary school students. Their attitude towards vaccination was positive but most of them wanted more information before considering vaccination.

Integrating clinical, community, and policy perspectives on human papillomavirus vaccination

Infection with genital human papillomavirus (HPV) may cause anogenital cancers, oropharyngeal cancers, anogenital warts, and respiratory papillomas. Two prophylactic vaccines (a bivalent and a quadrivalent vaccine) are now licensed and currently in use in a number of countries. Both vaccines prevent infection with HPV-16 and HPV-18, which together cause approximately 70% of cervical cancers, and clinical trials have demonstrated 90%-100% efficacy in preventing precancerous cervical lesions attributable to HPV-16 and HPV-18. One vaccine also prevents HPV-6 and HPV-11, which cause 90% of genital warts. A growing literature describes psychosocial, interpersonal, organizational, and societal factors that influence HPV vaccination acceptability. This review summarizes the current literature and presents an integrated perspective, taking into account these diverse influences. The resulting integrated framework can be used as a heuristic tool for organizing factors at multiple levels to guide intervention development and future research.

Maternal acceptance of human papillomavirus vaccine in Malaysia

Acceptability rates of human papillomavirus (HPV) vaccination by 362 Malaysian mothers were 65.7% and 55.8% for daughters and sons, respectively. Younger mothers, and those who knew someone with cancer, were more willing to vaccinate their daughters. If the vaccine was routine and cost free, acceptability rate was 97.8%.

Human papillomavirus vaccine and adolescents

PURPOSE OF REVIEW

The present review describes recent advances in our understanding about the epidemiology of human papillomavirus infection among female adolescents and describes several adolescent-specific issues related to administering human papillomavirus vaccines.

RECENT FINDINGS

National estimates demonstrate that human papillomavirus infection is most prevalent among adolescents and young adults. Parents, patients, and providers have a high interest in vaccination against this virus, but current patterns of adolescent healthcare utilization suggest that changes in adolescent preventive care delivery may be needed to provide these vaccines in a timely manner. Debate over whether adolescents should be legally allowed to self-consent to vaccination is another issue that remains unresolved and could have a substantial impact on vaccination rates. Legislation on school entry requirements related to human papillomavirus vaccination has been introduced in many states as a mechanism to circumvent some of these concerns, but the details of this legislation and its effect on adolescent vaccine utilization remain to be determined.

SUMMARY

Female adolescents are at a high risk for human papillomavirus infection and are likely to derive significant benefits from vaccination against this virus. However, administering human papillomavirus vaccines to this age group will require providers to be familiar with several issues unique to the adolescent population.

Young multiethnic women's attitudes toward the HPV vaccine and HPV vaccination

OBJECTIVE

To investigate the acceptability of the HPV vaccine among a multiethnic sample of young women in Malaysia.

METHODS

A qualitative study of 40 young women aged between 13 and 27 years recruited into 7 focus groups to discuss their knowledge of HPV infection, and their attitudes toward and acceptance of the HPV vaccine. The women were divided into Malay, Chinese, and Indian groups to allow for comparison among ethnicities.

RESULTS

Poor knowledge about HPV did not influence the HPV vaccine's acceptability. Although participants were in favor of the vaccine, the majority preferred to delay vaccination because it is newly introduced, they did not perceive themselves to be at risk of HPV infection, or because of cost factors. Concerns were raised regarding the vaccine's safety, the potential to be perceived as promiscuous and sexually active, and whether the vaccine was halal.

CONCLUSION

Promotion of the HPV vaccine should take account of social and cultural acceptability. The findings will help develop strategies for effective vaccination initiatives in a multiethnic and multireligious Asian society.
