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

From awareness to acceptance: understanding HPV and vaccine knowledge, attitudes and beliefs among university students in Punjab, Pakistan

Background

Human Papillomavirus (HPV) infections can lead to various cancers globally, and immunization can prevent HPV-associated cancers. This study intended to evaluate university students' knowledge, awareness, and attitudes/beliefs toward HPV and HPV vaccine uptake in Punjab, Pakistan.

Methods

A descriptive cross-sectional study was conducted in ten institutes across six cities using pre-validated questionnaires. Descriptive statistics and Rasch analysis were utilized to describe awareness levels, knowledge, and attitudes scores respectively. Regression analysis was utilized to explore association between demographic factors, knowledge levels, and attitudes/ beliefs. SPSS® (IBM, version 23.0) and Winstep® (version 3.75.0) software were used for analysis.

Results

Out of 1200 students approached, 1056 responded (response rate 88.0%). The mean age of students was 19.5 ± 0.5 years; 31.3% had heard about HPV, 16.4% were aware of the HPV vaccine's availability, and 2.3% were vaccinated against HPV. The mean Rasch knowledge score was -0.368 logits (SD: 0.893; SEM: 0.027), depicting below-average HPV knowledge. The mean Rasch attitudes/beliefs score was 0.049 logits (SD: 1.013; SEM: 0.031), which depicted positive attitudes towards HPV and its vaccination. Females (OR:1.742; 95%CI: 1.352-2.320), health-sciences students (OR: 1.692; 95%CI: 1.290-2.220), and urban residents (OR:1.621; 95%CI: 1.244-2.223) possessed positive attitudes towards HPV vaccination. Recommendations from physicians (Median: 4.0; IQR: 4.0-5.0) followed by parents (Median: 4.0; IQR: 3.0-5.0), and friends (Median: 4.0; IQR: 3.0-4.0) shaped vaccination decisions.

Conclusion

Despite their inadequate knowledge levels and poor vaccine uptake, students showed positive attitudes towards HPV vaccination. Awareness about HPV, including testing and vaccination, should be raised through community outreach programs, social media, and university curricula.

Determining the relationship between gynecologic cancer awareness and health literacy among women of reproductive age: a descriptive study

PURPOSE

To determine the relationship between gynecologic cancer awareness and health literacy among women of reproductive age.

METHODS

This study was conducted in a descriptive design and involved 510 women. Data collection utilized the "Personal Information Form", "Gynecologic Cancer Awareness Scale (GCAS)" and "Health Literacy Scale (HLS)", gathered. Pearson correlation and linear regression analyses, independent samples t-test, one-way analysis of variance and post hoc analyses were employed for data analysis. Effect sizes were calculated using eta-squared (η2) coefficients.

RESULTS

The mean total score of women on the GCAS was 154.42 ± 18.27, while the mean total score on the HLS was 57.07 ± 7.86. Significant differences were observed in women's GCAS total scores concerning age, perceived income status, and history of gynecological examination, whereas significant differences were noted in HLS total scores concerning age, educational status, marital status, and perceived income status. A weak positive correlation was detected betwixt women's GCAS and HLS total scores. It was determined that 20.8% of the total variation in gynecologic cancer awareness level was explained by health literacy.

CONCLUSION

Women exhibit an above-average level of awareness regarding gynecologic cancers. Health literacy level contributes to an increase in gynecologic cancer awareness.

Determination of the Relationship Between Gynecological Cancer Awareness and Fear of Cancer in Women Using Social Media and the Affecting Factors

BACKGROUND

Understanding the relationship between fear of gynecological cancer and awareness of cancer in women may help oncology nurses increase women's participation in gynecological cancer screening.

OBJECTIVE

To examine the relationship between women's gynecological cancer awareness and cancer fear using social media and the affecting factors.

METHODS

In a descriptive and cross-sectional study design, online data were collected from 1231 women aged 20 to 69 years through social media using the Descriptive Information Form, the Gynecological Cancer Awareness Scale (GCAS), and the Cancer Worry Scale (CWS). Analytic tests included paired t tests, analysis of variance, and post hoc correlations and structural equation modeling.

RESULTS

The women's total mean GCAS score was above moderate (152 ± 17), and their mean CWS score was high (19 ± 5). There was no relationship between the GCAS and CWS mean scores. Characteristics of participants with high awareness of gynecological cancer were being young, having a high educational level, having children, living in a province, having a history of cancer or family history of cancer, and having regular gynecological examinations, Papanicolaou smear tests, breast self-examination, and vulva examinations ( P < .05). The fear of cancer was higher in women with children, a family history of cancer, and regular gynecological examination behaviors ( P < .05).

CONCLUSION

Awareness of gynecological cancer was not significantly statistically associated with fear of cancer. Certain sociodemographic and gynecological characteristics are associated with awareness of gynecological cancer and/or fear of cancer.

IMPLICATIONS FOR PRACTICE

Oncology nurses may plan individualized or large-scale educational events that may make use of social media to enhance accurate awareness of gynecological cancer and related examinations in women.

Analysis of multi-site HPV infection and vaccination willingness among men who have sex with men in Tianjin, China

Background

Men who have sex with men (MSM) are vulnerable to HPV infection. This study aims to explore the HPV infection status at different sites among HIV-positive MSM, HIV-negative MSM, and men who have sex with women (MSW), and to investigate their willingness to receive HPV vaccination.

Methods

From September 2023 to April 2024, three groups were recruited in Tianjin, China. Participants completed an electronic self-administered questionnaire, which included demographic information, knowledge related to sexually transmitted diseases, behavioral information, and willingness to receive the HPV vaccine. Samples were collected from the anal region, genitals, and oral cavity for HPV typing.

Results

A total of 1,559 participants were recruited, including 300 HIV-positive MSM, 600 HIV-negative MSM, and 659 MSW. The HPV infection prevalence for any site were 62.0, 53.7 and 8.3%, respectively (p < 0.001). The infection prevalence for HPV genes covered by the 9-valent vaccine were 47.0, 36.8, and 3.5%, respectively (p < 0.001). Co-infection prevalence at anal and genital were 20.3, 14.2, 0.6%, respectively. Co-infection prevalence at anal and genital and oral were 1.3, 0.3%, 0, respectively. A total of 77.0% HIV-positive MSM and 75.3% HIV-negative MSM expressed willingness to receive the HPV vaccine, whereas 58.9% of MSW were unwilling (p < 0.001). Being HIV-positive (aOR, 3.119; 95% CI, 2.213-4.395), being over 46 years old (aOR, 1.994; 95% CI, 1.266-3.142), with an occupation classified as "white collar workers" (aOR, 1.620; 95% CI, 1.111-2.362) and "freelancing" (aOR, 2.025; 95% CI, 1.371-2.993) and a history of homosexual behavior in the past 6 months (aOR, 5.338; 95% CI, 3.802-7.495) were risk factors for HPV infection among men in Tianjin. Consistently using condoms in the past 6 months (aOR, 0.667; 95% CI, 0.513-0.867) were protective factors.

Conclusion

The HPV infection prevalence among MSM in Tianjin is significantly higher than among MSW, with higher prevalence in the anal region compared to the genital and oral region. HPV infection is associated with HIV infection, older age, and homosexual behavior. Most MSM showed a positive willingness to receive the HPV vaccine, indicating the necessity to implement targeted HPV vaccination programs for MSM and to enhance necessary preventive knowledge and behavioral interventions.

Women's knowledge, attitude, and practice regarding cervical precancerous lesions: a cross-sectional study in Beijing, China

Background

This study aimed to examine the knowledge, attitude, and practice (KAP) of women in Beijing regarding cervical precancerous lesions.

Methods

This web-based, cross-sectional study included women at Dongzhimen Hospital of Beijing University of Chinese Medicine between March 13, 2024 and April 9, 2024. A self-administered questionnaire was developed to collect participants' demographic information and KAP scores toward cervical precancerous lesions.

Results

The study included 951 valid questionnaires, with a mean age of 40.0 years. The mean knowledge, attitude, and practice scores were 12.55 ± 6.23 (possible range: 0-26), 50.66 ± 7.48 (possible range: 13-65), and 26.13 ± 4.98 (possible range: 7-35), respectively. The knowledge score (OR = 1.071, 95%CI: 1.040-1.103, p < 0.001), currently married (OR = 0.548, 95%CI: 0.304-0.985, p = 0.045), and with a history of HPV infection (OR = 2.302, 95%CI: 1.062-4.990, p = 0.035) were independently associated with the attitude score. The knowledge score (OR = 1.155, 95%CI: 1.119-1.192, p < 0.001), monthly income >20,000 (OR = 2.793, 95%CI: 1.249-6.248, p = 0.012), a history of HPV infection (OR = 0.380, 95%CI: 0.222-0.650, p < 0.001), unknown HPV infection status (OR = 0.289, OR = 0.177-0.473, p < 0.001), vaccinated against HPV (OR = 1.752, 95%CI: 1.221-2.514, p = 0.002), giving birth to one child (OR = 1.991, 95%CI: 1.186-3.341, p = 0.009), and giving birth to two or more children (OR = 2.160, 95%CI: 1.240-3.763, p = 0.007) were independently associated with the practice score. The structured equation model showed that knowledge directly influenced attitude (β = 0.237, p = 0.004) and practice (β = 0.490, p = 0.010). Attitude directly influenced practice (β = 0.193, p = 0.009).

Conclusion

This study revealed inadequate knowledge, moderate attitude, and practice toward cervical precancerous lesions among women in Beijing. Educational interventions should be developed to enhance knowledge in this regard.

Global parental acceptance, attitudes, and knowledge regarding human papillomavirus vaccinations for their children: a systematic literature review and meta-analysis

BACKGROUND

This systematic literature review aims to summarize global research on parental acceptance, attitudes, and knowledge regarding human papillomavirus vaccinations.

METHODS

The literature search was conducted in PubMed, Web of Science and Scopus, and included publications from 2006 to 2023. Study quality was assessed using the Newcastle-Ottawa Scale. The Grading of Recommendations Assessment, Development, and Evaluation guidelines were used to assess the strength of evidence for the primary outcome. Meta-analyses were performed using random-effects models to estimate pooled parental acceptance of HPV vaccinations. Studies were stratified by study years, and a subgroup analysis was conducted to estimate vaccine acceptance rates by world regions. Additionally, sensitivity analyses examined the role of parents in accepting HPV vaccinations for children of different sexes.

RESULTS

Based on 86 studies, we found that parents generally supported HPV vaccinations for their children, yet HPV vaccine acceptance rates showed high variation (12.0 to 97.5%). The subgroup analysis revealed geographical variations in pooled parental HPV vaccine acceptance rates, with the highest rate observed in Africa (79.6%; 95% CI: 73.5-85.2; I² = 98.3%; p < 0.01) and the lowest in North America (56.7%; 95% CI: 49.3-64.0; I² = 99.4%; p < 0.01). Sensitivity analyses showed that acceptance was higher for daughters than for sons, with mothers more willing to get their daughters vaccinated. The proportion of parents reporting barriers or benefits regarding HPV vaccinations varied widely (0.3-95.8%) between study regions. Across all world regions, fear of adverse effects and concerns about vaccine safety were the main barriers, whereas the desire to protect their children from cancer was a significant predictor of vaccine acceptance. Knowledge levels varied widely (6.5 to 100%) between world regions and according to the questions asked. In most studies, knowledge e.g., that HPV is sexually transmitted, and that HPV vaccination provides protection against cervical cancer, ranged from moderate to high.

CONCLUSIONS

The results indicated moderate parental acceptance of HPV vaccines. Public knowledge of HPV infection should be promoted, and special efforts should be made to minimize the existing barriers and increase vaccination accessibility and uptake.

Parental willingness to vaccinate their daughters against human papilloma virus and its associated factors in Woldia town, Northeast Ethiopia

Background

The cells of the cervical epithelial wall are the source of the malignant tumor caused by the human papilloma virus (HPV) known as cervical cancer. In 2018, Ethiopia implemented the HPV vaccine specifically targeting girls aged 9-14 years. This vaccination initiative serves as an effective preventive measure against cervical cancer, provided that parents express a positive inclination to have their daughters vaccinated as part of the program.

Objective

The aim of the study was to assess parental willingness to vaccinate their daughters against human papillomavirus and its associated factors in Woldia town, Northeast Ethiopia.

Methods

A community-based cross-sectional study was conducted among 414 parents of daughters aged 9-14 years between 10 and 25 January 2023. Respondents were selected by a systematic sampling method and a face-to-face interview was conducted to collect data. Data were entered into Epi Data version 4.6 and exported to SPSS version 25 for analysis. Multivariable analyses were used to examine the association between dependent and independent variables. The adjusted odds ratio (AOR), 95% confidence interval (CI), and p-value <0.05 were used to determine statistical significance.

Results

A total of 410 study participants with a response rate of 99% were included in the study, and approximately 72.9% (95% CI: 68.3-77.2) of them were willing to vaccinate their daughters. This study found that parents with a family history of cervical cancer screening (AOR = 3.27, 95%; CI = 1.38-7.74), secondary and above educational status (AOR = 2.72, 95% CI = 1.29-5.73), good knowledge of the human papilloma virus vaccination (AOR = 3.00, 95% CI = 1.70-5.28), and favorable attitude toward the human papilloma virus vaccine (AOR = 4.40, 95% CI = 2.45-7.88) were significantly associated with parental willingness to vaccinate their daughters against human papilloma virus.

Recommendation

In this study, most parents were willing to vaccinate their daughters against human papilloma virus. The significant determinants of parental willingness to their daughter's human papilloma virus vaccination were family history of cervical cancer screening, level of education, and knowledge and attitude toward the human papilloma virus vaccine. Therefore, health information regarding the human papillomavirus vaccination with an emphasis on raising community awareness should be designed.

Awareness of HPV vaccine and its socio-demographic determinants among the parents of eligible daughters in Bangladesh: A nationwide study

Background

Vaccination against Human papillomavirus (HPV) is recommended to avoid HPV infections and its associated diseases, including cervical cancer. However, there is no awareness study among Bangladeshi population. Hence, this nationwide study was conducted to explore HPV vaccine awareness and its determinants among parents of eligible adolescent girls.

Methods

This study was conducted among the parents of daughters aged 9-15 years from 42 out of 64 randomly selected districts of Bangladesh between June 28 to August 2, 2023. A multistage sampling method was used to enroll 2151 study participants from all eight divisions of Bangladesh. A semi-structured questionnaire was used for face-to-face interviews in this study. The statistical software Stata (Version 17) was used for statistical analyses.

Results

The average age of the participants was 38.18 (±5.86) years. Only 22.32 % of the participants were aware of the HPV vaccine. Every additional year of age increased the likelihood of being aware of the HPV vaccine by 3 % (AOR: 1.03; 95%CI: 1.00-1.06). Participants residing in the urban area had 3.56 times higher odds of awareness than rural and semi-urban people. Businessmen and housewives had 60 % (AOR: 0.40; 95 % CI: 0.22-0.69) and 77 % (AOR: 0.23; 95 % CI: 0.16-0.33) lower odds in comparison to job holders. The lower-income group exhibited significantly higher odds of awareness (AOR: 0.25, 95%CI: 0.16-0.39) compared to the middle and the higher-income group. Participants who never went through routine health check-ups had 77 % lower odds of being aware than those who availed of regular routine check-ups (AOR: 0.23; 95%CI: 0.16-0.34).

Conclusion

Awareness of the HPV vaccine among the general population of Bangladesh is very low. Age, residence, occupation, monthly income, and routine medical check-ups were associated with HPV vaccine awareness. A nationwide awareness campaign would increase this awareness level among the Bangladeshi population, especially among the parents of daughters.

Knowledge and Attitudes toward Human Papillomavirus and Vaccination: A Survey among Nursing Students in Saudi Arabia

INTRODUCTION

One of the most prevalent conditions affecting the vaginal organs is the human papilloma virus (HPV). Human papillomavirus (HPV) knowledge and attitudes have been the subject of numerous studies in Saudi Arabia. However, there are only a few studies that have examined university students' attitudes and knowledge of the human papillomavirus and the vaccine that is associated with it.

AIM

To predict the level of knowledge and attitudes regarding HPV and its related vaccine among undergraduate nursing students.

METHODOLOGY

This was descriptive cross-sectional research. After being selected from Princess Nourah bint Abdulrahman University's College of Nursing, 307 nursing students agreed to take part and completed an online survey that was self-administered.

RESULTS

The majority of the participants (73.5%) had a low level of knowledge of HPV with a mean score of 2.77 ± 1.78. In addition, more than half of the participating nursing students (57%) had a moderate attitude toward HPV vaccination with a mean score of 51.18 ± 11.16. The study results also verified that there was a highly significant correlation between the nursing students' demographics and their knowledge and attitudes toward HPV (p < 0.001). According to the SEM, nursing students' knowledge regarding HPV accounted for 48% of the variance in students' attitudes.

CONCLUSION

Nursing students' knowledge regarding HPV vaccination is an important predictor of students' attitudes regarding HPV.

Awareness of HPV and HPV vaccines, acceptance to vaccination and its influence factors among parents of adolescents 9 to 18 years of age in China: A cross-sectional study

BACKGROUND

Vaccination uptake rates for adolescents are still low in China despite safe and effective human papillomavirus vaccines being available. The awareness and attitudes of parents to HPV vaccines play a decisive role in adolescents' HPV vaccination uptake.

METHODS

A cross-sectional study was conducted from March, 2022 to May, 2022 using an anonymous questionnaire among parents of 9 to 18 years of age from 73 cities in 23 provinces in mainland China. Demographic characteristics of parents, their knowledge and attitudes about HPV and HPV vaccination, as well as factors influencing HPV vaccination in adolescents were assessed.

RESULTS

More than two-thirds of parents heard of HPV (75.5%) and HPV vaccines (84.7%). Of these participants, mothers (83.8%) were in the majority. Parents willing to vaccinate themselves and their children against HPV were 84.9% and 87.6%, respectively. Parents were more likely to vaccinate their daughters against HPV than their sons (P < 0.001). Parents who had heard of the HPV vaccines (P = 0.028) or had vaccinated themselves (P < 0.001) were more likely to have HPV vaccination for their children. Parents who accepted the price of the HPV vaccines (P = 0.005) were more likely to have their children vaccinated against HPV.

CONCLUSIONS

Children's gender, awareness of the HPV vaccines, parental HPV vaccination, and the price of the HPV vaccines are likely to be the reason for parents' vaccine hesitancy for adolescents.

PRACTICE IMPLICATIONS

Nurses have a critical role in identifying parental hesitancy and providing individualized education to expand the parental awareness and knowledge and encourage on-time adolescents vaccination.

Awareness, Acceptance, and Associated Factors of Human Papillomavirus Vaccine among Parents of Daughters in Hadiya Zone, Southern Ethiopia: A Cross-Sectional Study

INTRODUCTION

Human papillomavirus infections are the most prevalent sexually transmitted disease among women worldwide. Cervical cancer is the second-most frequent disease worldwide in terms of incidence and mortality, and it is primarily responsible for fatalities in low- to middle-income nations, including Ethiopia.

OBJECTIVE

To assess awareness, acceptance, and associated factors of the human papillomavirus vaccine among parents of daughters in the Hadiya zone, southern Ethiopia.

METHODS

From November to December 2021, a community-based cross-sectional study was conducted in the Hadiya zone among parents with daughters in the zone. The study respondents were chosen using a two-stage sampling technique from parents with a 9-14-year-old daughter. An interviewer-administered questionnaire was used to collect data. For analysis, the data were entered into Epidata version 3.1 and exported to SPSS version 25. Variables with a p-value less than 0.25 in the bivariate analysis were transferred to multivariable analysis. A logistic regression model was applied to forecast the association between the predictor and outcome variables. Statistical significance was considered at a 0.05 p-value.

RESULTS

The study showed that the overall acceptance of parents to vaccinate their daughters with HPV vaccination was 450 (84.9%). Parents of daughters of male sex (AOR: 0.407; 95%CI: 0.221, 0.748), who had only one daughter (AOR: 2.122; 95%CI: 1.221, 3.685), whose daughter(s) attended a government school (AOR: 0.476; 95%CI: 0.263, 0.861), who had poor knowledge (AOR: 0.532; 95%CI: 0.293, 0.969) and who had a negative attitude (AOR: 0.540; 95%CI: 0.299, 0.977) were discovered to have a strong correlation.

CONCLUSION

This study found that there was a high level of parental acceptance; attitudes and knowledge about the HPV vaccine are significant in determining their intentions to vaccinate their daughter. Authorities in high-risk areas for cervical cancer incidence should plan and implement strategies by providing health information regarding human papillomavirus vaccination with an emphasis on raising community awareness.

Pre-Procedural Anxiety and Associated Factors Among Women Seeking for Cervical Cancer Screening Services in Shenzhen, China: Does Past Screening Experience Matter?

Background

Research gaps exist in addressing the psychological harm related to the cervical cancer screening. Anxiety is the most common distress driven by the screening procedures, which may be affected by past screening experience (PSE) but with uncertainty. This study aimed to evaluate the pre-procedural anxiety in cervical cancer screening and to identify the influence attributed to PSE.

Methods

A cross-sectional survey targeted women seeking for cervical cancer screening services was conducted from June 5th to December 31st, 2020 in Shenzhen. The 20-item state anxiety scale of the State-Trait Anxiety Inventory (STAI-S) was applied to measure pre-procedural anxiety, in which a score of 40 or higher was regarded with anxiety symptom. Logistic regression models were established to explore potential associated factors of pre-procedural anxiety both for women with and without PSE.

Results

Overall, 3,651 women were enrolled, in which 36.1% had never been screened and the remaining 63.9% had been screened at least once before. Women without PSE demonstrated more prevalent pre-procedural anxiety (74.5% vs. 67.8%, P <0.001) than their experienced counterparts. Among women without PSE, having heard of cervical cancer screening was associated with a lower likelihood of pre-procedural anxiety (OR: 0.37, 95%CI: 0.25~0.56). Among experienced women, participating three or more times screening was negatively associated with anxiety symptom (OR: 0.67, 95%CI: 0.53~0.84), however, both receiving screening within three years (OR: 1.58, 95%CI: 1.27~1.97) and unknowing previous screening results (OR: 1.42, 95%CI: 1.11~1.82) increased the susceptibility of pre-procedural anxiety.

Conclusions

Women participating in cervical cancer screening commonly present pre-procedural anxiety. The association between PSE and pre-procedural anxiety may be influenced by past screening times, interval, and results. Psychological counseling according to women’s PSE before cervical cancer screening is warranted of necessity.

Acceptability of Human Papilloma Virus Self-Sampling for Cervical Cancer Screening in a Cohort of Patients from Romania (Stage 2)

(1) Background: Low patient’s adherence to conventional cervical cancer screening methods determined the need to take into consideration alternative approaches, and vaginal HPV self-sampling is one of them. We aimed to evaluate, using an online survey, the Romanian women’s acceptability of vaginal HPV self-sampling. (2) Methods: A 13-questions online survey was distributed on three Facebook groups, and the results were summarized. (3) Results: Despite of good educational background, 10.8% (n = 60) of the respondents did not know what a Pap smear is, and 33% (n = 183) were not informed about the free national cervical cancer screening program. Multivariate analysis revealed an increased likelihood of vaginal self-sampling acceptance among respondents who did not know about Pap test (OR: 7.80; 95%CI: 1.062−57.431; p = 0.021), national cervical cancer screening program (OR: 1.96; 95%CI: 1.010−3.806; p = 0.02), HPV infection (OR: 7.35; 95%CI: 3.099−17.449; p< 0.001) or HPV test (OR: 1.67; 95%CI: 0.950−2.948; p = 0.03). Moreover, women who did not previously undergo a cervical cancer screening program were more likely to accept the new screening method (OR: 1.62; 95%CI: 0.878−3.015; p = 0.04). (4) Conclusions: Our results showed high acceptability rates of vaginal HPV self-sampling among participants.

Awareness about Gynecologic Cancers and Related Factors among Healthy Women: A Cross-Sectional Study

The risk of cancer-related mortality and morbidity decreases when women are aware of the risk factors for gynecologic cancers and implement strategies such as attending relevant early screening programs. This cross-sectional study conducted between August 2017 and August 2018 at a public hospital in Turkey aimed to determine the awareness about gynecologic cancers among healthy women by utilized the Krieger's ecosocial theory as a framework for the study. The study included 554 Turkish women aged 18-65 years. Data were collected using the Gynecological Cancer Awareness Scale (GCAS) and a questionnaire designed in this study. Significant differences were noted between the average GCAS score and variables such as the amount of menstrual bleeding, entering menopause, a history of reproductive system disease, regular gynecological examination (including Pap test), regular vaginal self-examination, sexually transmitted infections (STIs), genital hygiene behavior, the fear of having cancer, having knowledge about cancer, and requiring information about cancer (p < .05). Despite the high level of awareness about gynecologic cancer among these women, the lack of proper knowledge and preventive measures was high. Having knowledge about gynecologic cancers results in increased awareness; however, the level of knowledge is not sufficient to prevent gynecologic cancers, which shows the need for sufficient and effective cancer screening and education programs.

Genital Human Papillomavirus Prevalence and Genotyping Among Males in Putuo District of Shanghai, China 2015-2019

BACKGROUND Reports of human papillomavirus (HPV) infection and genotype distribution in Chinese men are limited, and HPV vaccination has not yet been recommended for men in China. MATERIAL AND METHODS We retrospectively reviewed the prevalence and genotyping of male genital HPV. A total of 1227 male patients (aged 17 to 81 years) attending the dermatology and sexually transmitted disease clinics at Putuo District Center Hospital in Shanghai from 2015 to 2019 were included. Genital exfoliated specimens were obtained for detection and genotyping of 27 HPV types by Luminex-based multiplex assay. RESULTS The prevalence of any HPV was 65.5% (804/1227). The rate of multiple infection was 25.8% (317/1227). The 5 main HPV types were 6 (32.0%), 11 (23.2%), 16 (5.6%), 43 (4.3%), and 59 (4.0%). Among all detected HPV genotypes, 65.5% (875/1336) were 9-valent HPV genotypes. No significant differences were observed in the detection rate of HPV infection over 5 years (P>0.05). Age groups ≤24 years (70.7%) and ≥55 years (72.9%) showed higher infection rates, and significant differences were detected in rates of low-risk HPV infection in different age-stratified groups (P<0.05). Prevalence of HPV infection among patients with warts (74.4%) was significantly higher than that of patients with other clinical characteristics (40.4%) and physical examination (63.6%). CONCLUSIONS Our study suggested that more than half of Chinese male patients have detectable HPV infections, and penis-genital and anogenital warts were the most common clinical manifestations. Moreover, the available 9-valent HPV vaccine covers the most frequently observed HPV types among men.

Joint effects of HPV-related knowledge and socio-demographic factors on HPV testing behaviour among females in Shenzhen

BACKGROUND

Limited population-based studies explore the utilization and associated barriers or facilitators to cervical cancer screening in China. We attempted to investigate the associations of socio-demographic factors, HPV specific knowledge with HPV testing behaviour in Shenzhen, China.

METHODS

A citywide cross-sectional survey was conducted from January to June 2015 in Shenzhen city by using a multistage stratified cluster sampling method. Socio-demographic information, awareness and specific knowledge of HPV, practice of HPV testing, and HPV vaccination-related attitude were collected. Multivariate logistic regression model was used to analyse possible associations.

RESULTS

Approximately one third of total 8639 women aged from 30 to 60 years old had ever received HPV testing. Overall, 67.6% of all participants demonstrated low knowledge level of HPV. High HPV knowledge level was significantly associated with HPV testing behaviour (odds ratio: 3.792, 95% confidence interval: 3.400-4.230). The impact of residence and education on testing behaviour only turned to be significant if women had low level of HPV knowledge (P for multiplicative interactions: 0.001 and <0.001, respectively), whereas monthly income exerted promotion effects apparently among those with high knowledge level (P for multiplicative interaction: 0.037).

CONCLUSIONS

Our study revealed gaps in HPV knowledge and screening participation among Chinese women, and provided novel clues that women with high HPV knowledge level would be more appeal to involve in HPV testing behaviour. The influence of HPV-related knowledge on HPV testing also lies in the joint effects with socio-demographic factors, including residence, education and monthly income.

Awareness and Knowledge about Human Papilloma Virus Infection among Students at Secondary Occupational Health School in China

Cervical cancer (CC) is one of the most common causes of cancer-related deaths worldwide. CC is mainly caused by human papilloma virus (HPV), which can be prevented by vaccination. We conducted a cross-sectional study in secondary occupational health school (SOHS) through a questionnaire aimed to assess the awareness and knowledge regarding HPV infection of students. A total of 2248 students participated in the survey, 45.3% of them had heard about CC, while only 21.9% of them had heard about HPV; and 74.2% had no idea of the causal link between HPV infection and CC. Most participants displayed poor awareness and knowledge about HPV infection. The results suggested that age, grade, major, academic performance, etc. were correlated with higher awareness of CC, HPV and HPV infection (p < 0.05). In multivariable logistic analysis, third-grade students had the most increased awareness of CC (OR = 17.13, 95%CI: [8.11, 36.15]), HPV (OR = 6.59, 95%CI: [4.16, 10.43]) and HPV vaccine (OR = 2.78, 95%CI: [1.78, 4.32]) when compared to first-grade. Awareness and knowledge regarding HPV infection were insufficient among students in SOHS. As the future healthcare providers, these results highlight the need to supplement targeted education to improve their awareness and knowledge of HPV and vaccination.

NUP210 and MicroRNA-22 Modulate Fas to Elicit HeLa Cell Cycle Arrest

PURPOSE

Cervical cancer is one of the most fatal diseases among women in under-developed countries. To improve cervical cancer treatment, discovery of new targets is needed. In this study, we investigated the expression of NUP210, miR-22, and Fas in cervical cancer tissues and their functions in cell cycle regulation.

MATERIALS AND METHODS

We detected and compared the expression levels of NUP210, miR-22, and Fas in cervical cancer tissues with paired normal tissues using immunohistochemistry, Western blot, and real-time quantitative polymerase chain reaction. NUP210 was knocked down in HeLa cells via lentivirus, followed by cell cycle and proliferation analysis. Using a luciferase reporter assay, we explored the link between miR-22 and NUP210. We overexpressed miR-22 in HeLa cells and analyzed cell cycle and proliferation function. We then overexpressed miR-22 in NUP210 knockdown cells to explore the connection between Fas and miR-22-NUP210 signaling.

RESULTS

We found that NUP210 was overexpressed in cervical cancer patients. Knocking down NUP210 restored cell apoptosis and proliferation. We confirmed miR-22 as a regulator of NUP210 and verified that miR-22 was inhibited in cervical cancer development. We also found that restoring miR-22 expression could induce cell apoptosis. Finally, we found that miR-22-regulated expression of NUP210 could alter Fas expression and, in turn, elicit cell cycle arrest and proliferation.

CONCLUSION

miR-22 in cervical cancer is downregulated, resulting in NUP210 overexpression and inhibition of Fas-induced cell apoptosis.

Anal human papillomavirus among men who have sex with men in three metropolitan cities in southern China: implications for HPV vaccination

INTRODUCTION

Men who have sex with men (MSM), especially those infected with human immunodeficiency virus (HIV), are at disproportionate risk for human papillomavirus (HPV) infection. Data about anal HPV prevalence among MSM in southern China are limited.

METHODS

MSM were recruited between January 1 and August 31, 2017 in three metropolitan cities: Guangzhou, Shenzhen and Wuxi. A self-completed tablet-based questionnaire was used to collect information about socio-demographic/sexual behavioral characteristics, history of sexually transmitted infections (STIs) and recreational drug use. An anal brush was used to collect exfoliated cells for HPV DNA testing and genotyping, and a blood sample was taken for HIV testing. Penile/anal warts were checked by a clinician.

RESULTS

A total of 536 MSM were enrolled, including 39 HIV-positive and 497 HIV-negative individuals. Compared with HIV-negative MSM, prevalence of any HPV genotype (79.5% vs 46.7%), any high-risk genotype (64.1% vs 36.6%) and any nonavalent vaccine-preventable genotype (53.9% vs 31.6%) was significantly higher in HIV-positive MSM, with all P < 0.01. HIV infection (adjusted odds ratio [AOR], 4.28; 95% confidence interval [CI], 1.87-9.80), using recreational drugs (AOR, 1.87; 95% CI, 1.22-2.87), having ≥ 3 years of sexual experience (AOR, 1.52; 95% CI, 1.01-2.28), having ≥ 6 lifetime male partners (AOR, 1.92; 95% CI, 1.29-2.86), and engaging receptive anal intercourse (AOR, 2.30; 95% CI, 1.48-3.57) were associated with higher anal HPV prevalence. Any HPV prevalence increased with age, from 24.5% at < 20 years to 55.8% at ≥ 40 years.

CONCLUSIONS

Anal HPV prevalence was high among MSM in southern China, significantly associated with HIV status and sexual experience. HPV prevalence increased with age among MSM. A targeted HPV vaccination program for teenage MSM might be necessary. Our findings will inform targeted HPV modelling among MSM in China.
