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

Knowledge, attitudes, and perception toward human papillomavirus among health profession students: A cross-sectional study in King Saud Bin Abdulaziz University for Health Sciences

BACKGROUND

Human papillomavirus (HPV) infection is the major risk factor for cervical cancer (CC) in women of reproductive age. Despite advances in treatment and prevention of CC by HPV vaccination, very few women utilize them because of a lack of awareness about HPV.

MATERIALS AND METHODS

We conducted this cross-sectional study among Health Professions Students (HPS) at King Saud Bin Abdul Aziz University for Health Sciences, Jeddah. Data were collected using a predesigned and validated study questionnaire to assess the knowledge, attitude, and perception of HPS toward HPV.

RESULTS

A total of 580 HPS responded to the survey; 128 (22.1%) were male, while 452 (77.9%) were female with the mean age ± standard deviation 20.36 ± 1.74 years. There was no significant difference between males and females related to screening of HPV and CC (82.8%; 82.3%). A minority (30.3%) of participants thought that HPV infection leads to CC, while 38.3% did not know about it. Furthermore, knowledge about HPV screening and vaccination was poor.

CONCLUSIONS

Students from the college of medicine had more knowledge and awareness about HPV (34.9%, P < 0.001). Thus, it is important to implement effective education programs, curricular activities, and awareness campaigns for health professions to augment the learning process effectively.

Does group education affect mothers' knowledge and attitudes towards the HPV vaccine?

In this study the authors' investigated the effect of group education on human papillomavirus (HPV) on level of knowledge and health beliefs for HPV infection and vaccine. The study was semi-experimental with a pre- and post-test education model. In total, 110 mothers of secondary school students, 55 in education group, and 55 in control group participated. The groups were educated on different content and three evaluations (pre-education, post-education, and six months following the education) were made. HPV knowledge and belief scores of the education group increased compared to pre-education and control group scores (p < 0.001). Perceived barriers to vaccination were similar in both groups (p > 0.05). Group education increases awareness about HPV infection and vaccine.

HPV Infection, HPV Vaccines and Cervical Cancer Awareness: A Multi-Centric Survey Study in Istanbul, Turkey

Our purpose was to examine the level of knowledge and awareness about HPV (Human papillomavirus) infection, HPV vaccines, and cervical cancer of participants. This study was conducted at students and healthcare workers of Uskudar University as well as the healthcare workers of Umraniye Training and Research Hospital and patients admitted to the gynecology outpatient clinics. A 41-question survey was conducted that investigated the 700 participants' demographic characteristics, HPV infection and cervical cancer status, and attitudes toward vaccination. 44.1% of the participants stated that they knew the cause of cervical cancer, 42.8% did not. 55.9% of those who went to regular doctor control, 38.5% of those who did not, knew that the HPV vaccine prevented warts and cervical cancer. 63.4% of men and 75.4% of women stated that they did not know whether the vaccine was effective against penile, anal and laryngeal cancer. All these were found to be statistically significant (P < .05). Lack of knowledge on vaccine protection, insufficient knowledge regarding HPV, prevalence of prejudices, and overall opinions about health are the most prevalent public health concerns in Turkey.

Knowledge, Attitude, and Behavior of Teachers Regarding HPV (Human Papillomavirus) and Vaccination

This study aims to determine the knowledge, attitude, and behaviors of teachers regarding human papillomavirus (HPV) and its vaccination. This cross-sectional study included teachers from 30 schools of the Kahramanmaraş city between 01 March 2015 and 09 June 2015. The teachers were informed prior to the study, and 804 teachers giving written consents were enrolled. Nine questions (9 points) to ascertain the knowledge of teachers regarding HPV and 5 questions to detect the knowledge level about HPV vaccination were prepared from the literature. Of the participants, 448 (55.7%) were men and 356 (44.3%) were women with a mean age of 38.32 ± 8.36 (min = 23, max = 65) years. Of the teachers, 309 (38.4%) reported having heard about HPV before while 207 (25.7%) stated hearing about the HPV vaccine. The knowledge about HPV was mostly gained from the internet (n = 183, 22.8%). The mean knowledge score of HPV was 1.29 ± 1.57 in men and 1.76 ± 1.70 in women. The mean knowledge score about the HPV vaccination was 0.86 ± 1.06 in men and 1.14 ± 1.29 in women. The knowledge scores of female teachers regarding HPV and its vaccination were significantly higher compared with male teachers (p < 0.001, p = 0.001). We found that teachers' level of knowledge regarding HPV and its vaccination is lacking. Furthermore, we observed deficiency and mistakes in teachers' attitude and behaviors towards HPV and its vaccine. The knowledge deficiency of male teachers about HPV and vaccination compared with female teachers is remarkable.

Analysis of community-based studies related with knowledge, awareness, attitude, and behaviors towards HPV and HPV vaccine published in Turkey: A systematic review

Human papilloma virus (HPV) vaccine is a proven method for preventing HPV-related cancers and genital warts, especially preventing cervical cancer. It is aimed to systematically review and synthesize conclusions in detail from community-based studies published in Turkey between 2009 and 2019, which evaluate the knowledge, awareness, attitude, and behaviors of individuals towards HPV and HPV vaccination. This systematic review is conducted based on the PRISMA reporting method and includes community-based, descriptive cross-sectional and cross-sectional studies published between 2009 and 2019. In this systematic review, 5132 studies from six databases were scanned in total. It was determined that there were 23 studies that met the eligibility criteria for this systematic review. In the reviewed studies, it was determined that the rate of “Hearing of HPV before” was 3.8% at the lowest and 57.0% at the highest, and the rate of “Hearing of HPV vaccine before” was 2.2% at the lowest and 74.7% at the highest. In the reviewed studies, it was reported that although parents’ willingness to have their daughters vaccinated with HPV vaccine varied between 14.4% and 68.0%, their willingness to have their sons vaccinated with HPV vaccine varied between 11.0% and 62.0%. In addition, it was reported that the lowest rate of vaccination with HPV vaccine among participants was 0.3% at the lowest and 6.0% at the highest. Consequently, it is considered that conducting common, systematic, and continuous health education programs aimed at both sexes and including both parents, which will increase the knowledge and awareness on HPV and its vaccine, would provide positive attitudes, and will be effective in protecting against HPV-related cancers.

Intention to Pay for HPV Vaccination among Women of Childbearing Age in Vietnam

The intention to pay for human papillomavirus (HPV) vaccination among women of childbearing age in Vietnam, where cervical cancer remains a significant public health concern, has been mostly lacking. To examine this issue, we conducted a cross-sectional study of 807 pregnant women in an urban and a rural district (Dong Da and Ba Vi) of Hanoi, Vietnam. The vast percentage of our respondents expressed a firm intention to vaccinate, especially women in rural areas (over 90.0%). However, on being informed of the current price of the HPV vaccine, their intention to vaccinate dropped to about one-fifth of overall respondents, i.e., only 4.4% of women in rural areas. It was also observed that the initial intention to get the HPV vaccination among women in the rural district was about ten times higher than that of women living in the metropolitan district. Those participants who had greater knowledge of cervical cancer and HPV vaccinations also had a significantly higher intention to vaccinate. Our findings underscore the need to develop a well-designed vaccination program in Vietnam and other countries in a similar situation to increase the adoption of HPV vaccination.

Uptake of the HPV vaccine among people with and without HIV, cisgender and transgender women and men who have sex with men and with women at two sexual health clinics in Mexico City

Our aim was to better understand Human Papillomavirus (HPV) vaccine acceptance among Mexican adults including people with and without HIV, cisgender men who have sex with men (MSM) or with women (MSW), cisgender and transgender women. A computer-assisted, self-administered questionnaire was completed by healthcare users and participants recruited through community organizations, and the first dose of the quadrivalent HPV vaccine was offered at no cost at a large sexual health clinic in Mexico City, from May to December 2018. Socio-demographic characteristics and factors associated with HPV vaccine acceptance were analyzed using logistic regression.The sample of 1915 participants included 1341 cisgender men (70.9%, 1247 MSM and 94 MSW), 396 (20.7%) cisgender women and 178 (9.3%) transwomen; 615 people (32.1%) were HIV positive. Uptake of the HPV vaccine was higher in men and transwomen (91.5% and 87%, respectively) than among cisgender women (81.8%; p < .001). Cisgender women (OR 0.43, 95%CI 0.30-0.61, p < .05) were less likely to accept HPV vaccination than men. Married/partnered people were less likely to accept HPV vaccination compared to those who were single (OR 0.70, 95%CI 0.51-0.97). People living with HIV were not significantly more likely to accept HPV vaccination (OR 1.7; 95%CI 0.86-1.61).HPV vaccine acceptance was high among adult Mexican study participants; it may be higher than among other Mexican adults given most of these individuals are engaged in care. Modifications will be needed in national and international recommendations on HPV vaccination in adults if healthcare personnel are to recommend the vaccine to the population groups studied.

Awareness and Knowledge Levels of 18-Year-Old and Older Individuals Regarding Human Papillomavirus (HPV) and HPV Vaccine in Hatay, Turkey

The aim of this study was to evaluate the knowledge and awareness levels of 18-year-old and older women and men on HPV infection, HPV vaccine, and the potential risk factors in Hatay, Turkey. In our study, it was found that overall 27.0 and 23.2% of the participants reported having heard of HPV infection and HPV vaccine. The rate of participants who had heard of HPV infection and HPV vaccine was higher in women than in men (p < 0.000). Thirteen percent of the participants was aware of the fact that HPV triggers cervical cancer, 10.2% penile cancer, and 16.7% genital warts, respectively. The overall vaccination rate of the participants was 2.7%. When the total knowledge score of the participants about HPV infection and HPV vaccine was evaluated according to independent variables, it was found that being a woman, urbanization, and having a high level of education had a positive effect on knowledge score, while never having heard of HPV infection and HPV vaccine had a negative effect on knowledge score (p < 0.000). It was determined in the linear regression model that gender, educational status, residential area, and having heard of HPV infection before influenced knowledge levels. It was determined that the relation between these variables and the total knowledge scores of the participants was statistically significant (p < 0.05). It was also determined that women who had higher educational levels, those who were living in urban areas, and those who had heard HPV infection before had higher knowledge levels. The level of knowledge of the participants about HPV infection and HPV vaccine was found to be very low. Having adequate knowledge about HPV infection and increasing the acceptance of HPV vaccination in public will play an important role in decreasing the rate of mortality and morbidity of the different HPV-associated cancers in women and men.

Awareness and knowledge about cervical cancer prevention methods among Tunisian women

INTRODUCTION

Epidemiological and biological arguments put papillomavirus infection (HPV) as a determining factor in the etiology of cervical cancer. The main objective of this study is to assess the knowledge, attitudes and practices related to HPV prevention and cervical cancer screening among women living in the city of Sousse, Tunisia.

METHODS

Five hundred Tunisian women were interviewed face to face between May and June 2016. The questionnaire consisted in 14 questions relating participants' socio-demographic information, their awareness level, attitudes and practices regarding HPV and cervical cancer, including their understanding of the underlying cervical cancer etiology and preventive actions such as the Pap Smear test, and finally their acceptability and willingness to receive the anti-HPV vaccine under certain circumstances. Multivariate analyses were conducted to identify predictive factors of good acceptability of cervical cancer prevention methods.

RESULTS

Four hundred fifty-two questionnaires were completed and included in the analysis. The awareness of a sexually transmitted infection as an etiological agent for cervical cancer was expressed by 175 (38.7%) participants, the correct finality of the Pap Smear test by 308 (68%) and its recommended frequency by 176 (38.9%) respondents. Among all participants, 125 (27.7%) had undertaken the Pap Smear test at least once in their lifetime, 363 (80.3%) were interested in receiving the anti-HPV vaccine for themselves, 387 (86%) for their daughters and 405 (90%) approved the introduction of the anti-HPV vaccine in the Tunisian national program of vaccination.

CONCLUSIONS

The knowledge and awareness of HPV infection and cervical cancer among Tunisian women was found to be moderate (around 40%) and the acceptability of the anti-HPV vaccine was found to be high (over 80%). These results are concordant with the results of other studies conducted in other MENA countries.

Application of multiplex PCR for Rapid and sensitive detection of human papillomaviruses in cervical cancer

Objectives:

Reffering to an increase in cervical cancer in the recent years, rapid, sensitive and economical detection of human papillomaviruses (HPVs) as causative agents of cervical cancer is important. The traditional methods for the detection of HPVs in cervical cancer, such as pap smear, suffer from limitation and PCR has a potential to overcome the limitaitons. The purpose of present research work was to identify the five important strains of HPV (16, 18, 31, 33 and 45) simultaneously by Multiplex PCR application.

Methods:

Study was done on 100 cervical lesions of women. DNA was extracted from specimens by a genomic DNA purification kit. A 5-plex PCR was developed for the simultaneous detection of major HPV. Five pair of new primers was designed for detection of HPV 16, 18, 31, 33 and 45 by Multiplex PCR.

Results:

Among the 100 evaluated samples, 82 were found positive to HPVs. In the meantime the highest rate of infection was for HPV 16. Also 30 of HPV positive samples had infections with two or more HPV types.

Conclusion:

Multiplex PCR assay used in present study can provide a rapid, sensitive and economical method for detection of viral infections and is applicable to small volumes of vaginal samples.

High-risk human papillomavirus infection in the prediction of poor treatment response and disease recurrence in patients with vulvovaginal condyloma

OBJECTIVE

To determine the predictive factors for progression and recurrence of vulvovaginal condyloma (VVC), with a specific focus on high-risk HPV (HR-HPV) infections.

METHODS

Retrospective data were collected from 48 patients who were diagnosed with VVC and treated with topical trichloroacetic acid application or laser therapy during 2003-2014 at a hospital in South Korea. The diagnoses were made based on the presence of exophytic condylomatous lesions as assessed by direct visual inspection regardless of whether a biopsy was performed.

RESULTS

Overall, 18 patients (50.0% of those with a test result) were positive for HR-HPV. Three-quarters of the patients with a poor treatment response had abnormal cytologies, and abnormal cytology was a risk factor for a poor response (odds ratio, 4.33 [95% confidence interval, 1.05-17.84]). During a median follow-up of 24months, VVC recurred in seven (14.6%) patients. A high viral load (more than 50 relative light units) of HR-HPV was significantly associated with recurrence (odds ratio, 7.42, 95% confidence interval, 1.19-46.18).

CONCLUSION

A high HR-HPV load is a risk factor for recurrence, but is not related to treatment response. A poor treatment response is more related to abnormal cytology than it is to viral load.

Knowledge, attitudes, practices and barriers towards HPV vaccination among nurses in Turkey: a longitudinal study

BACKGROUND

Human papilloma virus (HPV) occurs in women of all age groups, and causes cervical, anal, vaginal, vulvar, penile and oropharyngeal cancers. The aim of the study was to discover what nurses know about HPV infection, testing and vaccination and to determine vaccine practice of their daughters and perceived barriers.

MATERIALS AND METHODS

This cross-sectional and prospective study was carried out nurses who have worked in a hospital between January and June 2014. Pre-test and post-test were used to evaluate the nurses' knowledge about HPV infection, testing and vaccination. This study was performed with nurses who had girls between 9 and 26 years of age for evaluating the behavior of vaccination after three months of education.

RESULTS

The mean of pre-test and post-test scores about HPV infection, which included 22 items, were 8.2±5.6 and 19.2±1.5, respectively. Before education the HPV testing knowledge score was remarkably poor (1.9±1.7 over 5), after education it increased to 4.8±0.5. The mean HPV vaccine knowledge score were 3.7±2.7 (pre-test) 7.3±0.8 (post-test) on a 0-8 scale. The difference between mean total pre-test (13.9±9.1) and post-test (31.3±1.9) scores was statistically significant (p<0.001). After three months of education, only two of the nurses' daughters were vaccinated. The main reason was noted by nurses were not willing to be vaccinated was cost, doubts about safety and efficacy related to the vaccine. About one-third of nurses declared that they would receive the vaccine for their daughter later.

CONCLUSIONS

Nurses have a crucial role in the prevention, treatment, increasing public awareness and care for population. The education of the nurses about HPV infection, test and vaccination will play an important part decreasing cancer mortality and morbidity.

Factors influencing the recommendation of the human papillomavirus vaccine by Serbian pediatricians

OBJECTIVES

This research was undertaken to investigate the knowledge and attitudes regarding Human Papillomavirus infection and the Human Papillomavirus (HPV) vaccine among pediatricians who work in primary health care and to determine their intention to recommend the HPV vaccine as an important measure for the primary prevention of cervical cancer. We assessed the factors associated with the intention to recommend the vaccine.

STUDY DESIGN

This cross-sectional study was conducted in March and April 2012. This research included all pediatricians who worked with school children in public primary health care institutions in Belgrade. A research instrument questionnaire had been designed for this study.

RESULTS

The response rate was 78.7%. The knowledge of pediatricians related to HPV infection and the HPV vaccine was estimated as poor. However, pediatricians recognized the need for additional education in this field. The most-frequently reported barrier to HPV vaccination was the financial concern (68.2%). Alternatively, according to the pediatricians, the most common parental barrier to vaccination was the lack of information on the vaccine (67.2%). Nearly two-thirds of the pediatricians were willing to recommend the vaccine (60.2%). The factors associated with the pediatricians' intention to recommend the vaccine included the parents' attitudes.

CONCLUSION

The majority of pediatricians accept the HPV vaccine and recommend it to their patients. It is necessary to improve cooperation between parents and pediatricians to increase immunization coverage and develop national consulting strategies with a focus on the prevention of HPV infection.

Knowledge Level of Human Papillomavirus, Cervical Cancer and Vaccination Status among Mothers with Daughters in High School

PURPOSE

The goal of this study was to examine knowledge level of human papillomavirus (HPV), cervical cancer, and vaccination status among Korean mothers' with a daughter in high school.

METHODS

A cross-sectional descriptive study was conducted with a convenience sample of 234 Korean mothers.

RESULTS

The mean score of HPV knowledge level was 4.21 out of 20, and cervical cancer knowledge was 3.88 out of 7. There were low levels of daughters' who received HPV vaccination (3.8%) and high levels of mothers' intention to get their daughters' vaccinated with HPV (85.0%). The major barrier to HPV vaccination was the concern for side effect from the vaccination. The most effective recommendation for HPV vaccination came from health care providers.

CONCLUSION

HPV educational programs targeting mothers of daughters in high school is needed. Future studies need to determine actual HPV vaccination rates and factors related to high uptake using a larger sample from various socioeconomic background.

Effect of an educational intervention on HPV knowledge and vaccine attitudes among urban employed women and female undergraduate students in China: a cross-sectional study

Background

Due to the potential of human papillomavirus (HPV) vaccination for decreasing cervical cancer rates in Mainland China, where some of the highest incidences in the world have been reported, our study aimed to assess HPV and HPV vaccine knowledge, and to evaluate the effect of a brief educational intervention on HPV knowledge and vaccine acceptability in Chinese undergraduate students and employed women.

Methods

This multi-center, cross-sectional study was conducted across five representative cities of the five main geographical regions of Mainland China. Participants were selected from one comprehensive university and three to four companies in each city for a total of six comprehensive universities and 16 companies. A 62-item questionnaire on HPV knowledge and HPV vaccine acceptability was administered to participants before and after an educational intervention. The intervention consisted of an informative group lecture.

Results

A total of 1146 employed women and 557 female undergraduate students were surveyed between August and November 2011. Baseline HPV knowledge was low among both groups— 320/1146 (28%) of employed women and 66/557 (12%) of students had heard of HPV, while only 237/1146 (21%) of employed women and 40/557 (7.2%) of students knew that HPV is related to cervical cancer. After educational instruction, 947/1061 (89%) of employed women and 193/325 (59%) of students knew the relationship between HPV and cervical cancer (χ2 = 1041.8, p < 0.001 and χ2 = 278.5, p < 0.001, respectively). Post-intervention, vaccine acceptability increased from 881/1146 (77%) to 953/1061 (90%), (p = <0.001) in employed women and 405/557 (73%) in students to 266/325 (82%), (p < 0.001). Women in both groups cited concerns about the HPV vaccine’s safety, efficacy, and limited use to date as reasons for being unwilling to receive vaccination. 502/1146 (44%) of women were willing to vaccinate their children at baseline, which increased to 857/1061 (81%) post-intervention, p < 0.001.

Conclusions

Incorporation of our lecture-based education initiative into a government-sponsored or school-based program may improve HPV-related knowledge and HPV vaccine acceptability. Further studies are needed to evaluate and standardize HPV education programs in China.
