Willingness to human papillomavirus (HPV) vaccination and influencing factors among male and female university students in China

Prevalence and determinants of vaccination intention towards routine immunizations in university students: a systematic review and meta-analysis

BACKGROUND

It is well known that, to be effective, vaccination programs require a high and consistent population uptake. Nevertheless, vaccine coverage is often insufficient. University students occupy a unique position within the broader population: they are highly mobile and socially active individuals who serve as influential figures among their peers and younger age groups, making them an ideal target for educational campaigns.

METHODS

This review (CRD42022309724) quantified the vaccination intention rates for routine immunizations in university students and systematically examined the determinants of vaccination acceptance. Cross-sectional studies that analyzed vaccination intention for at least one routine immunization using multivariable logistic regression were included. We used random-effects models to calculate the pooled proportions of vaccination intention. Determinants were categorized into contextual factors (such as socio-demographic, economic and cultural factors), individual/group factors (such as knowledge, awareness, peer opinions, infection risk perceptions) and vaccine-specific issues (such as vaccine effectiveness and vaccination policies).

RESULTS

Thirty-six articles were included: 29 on the human papilloma virus (HPV) vaccine and seven on the influenza vaccine. The pooled proportion of students intending to get vaccinated was 54% (95% CI: 47-60%) for HPV and 43% (95% CI: 26-61%) for influenza. The strongest positive determinants were individual/group factors, such as higher knowledge and awareness, pro-vaccine peer opinions, positive personal experience with vaccinations, and higher risk perception for HPV infection, and higher risk perception for infection and previous vaccination history for influenza. By contrast, contextual influences played a minor role in both vaccinations, while vaccine-specific concerns, particularly about costs and availability, negatively influenced intention for both vaccines.

CONCLUSIONS

Given the suboptimal rates of vaccination intention towards HPV and influenza vaccine that we found, addressing key determinants, such as awareness of infection risks and perception of vaccination benefits, is essential to increase vaccination acceptance in university students and to achieve high vaccination coverage.

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.

Prevalence and cognitive factors influencing high-risk HPV infection and cervical diseases in women aged 18-45 in Shijiazhuang city

This study aimed to investigate the prevalence of high-risk human papillomavirus (HPV) infection and the awareness levels regarding cervical diseases among women aged 18-45 in Shijiazhuang city. The objectives were to determine the incidence rates of high-risk HPV infections, analyze the patterns of cervical disease occurrence, and identify the factors influencing awareness within this demographic. A total of 544 women aged 18-45 participated in the study, with 102 testing positive for high-risk HPV infection. A structured questionnaire was administered to evaluate awareness of high-risk HPV and cervical diseases. The survey collected data on infection prevalence, subtype distribution, incidence rates, knowledge levels, and factors affecting awareness related to high-risk HPV infections and cervical health. Among the 544 women screened, 102 (18.75%) were diagnosed with high-risk HPV. HPV-16 emerged as the most prevalent subtype, followed by HPV-52 and HPV-58. Of the positive cases, 38 displayed no signs of intraepithelial neoplasia or malignant lesions, while 38 had atypical squamous epithelium, predominantly associated with HPV-52. Low-grade intraepithelial neoplasia was observed in 15 cases, and high-grade neoplasia was found in 11 cases, both primarily linked to HPV-16. Awareness levels varied, with 87 participants demonstrating low knowledge and 15 showing higher awareness. Logistic regression analysis identified education, occupation, residence, and access to scientific knowledge as significant factors influencing awareness and infection risk (P < .05). The prevalence of high-risk HPV infection among women aged 18-45 in Shijiazhuang city is relatively low, with HPV-16 being the predominant subtype. HPV-16 was strongly associated with cervical epithelial neoplasia and cervical cancer. Targeted educational interventions, particularly for populations with lower education levels and those in rural areas, are recommended to enhance awareness and improve the prevention and control of HPV-related infections and cervical diseases.

A Computational Framework Analysis of Public Attitudes Toward Male Human Papillomavirus Infection and Its Vaccination in China: Based on Weibo Data

BACKGROUND/AIMS

The global promotion of HPV vaccines has underscored the importance of vaccination for both males and females in reducing disease transmission and associated complications. Despite robust evidence supporting male HPV vaccination, China has yet to approve it. Public discussions on male HPV vaccination, influenced by policy delays, gender norms, and commercialization, reveal diverse attitudes and significant challenges in achieving equitable health outcomes. This study investigates public perceptions and attitudes toward male HPV vaccination in China by analyzing cognitive frames and the social, cultural, and economic factors shaping these discussions.

METHODS

This study employs a cross-sectional design to analyze 4997 Sina Weibo posts using the Analysis of Topic Model Networks (ANTMN), identifying five frames: Disease Risk and Prevention, Virus Transmission, Gender Roles and Perceptions, Vaccine Promotion and Acceptance, and Market Dynamics and Consumption.

RESULTS

The findings reveal a significant gap between policy implementation and public awareness of male HPV vaccination in China. Despite growing recognition of its benefits, entrenched gender norms and biases hinder equitable health outcomes. Social media, as a pivotal platform for health communication, plays a dual role in facilitating public discourse while also amplifying misinformation. Policy delays and concerns over vaccine commercialization heighten public hesitancy, emphasizing the need for inclusive policies and targeted education.

CONCLUSIONS

This study highlights the necessity for systemic efforts to address gender biases, enhance public education on male HPV vaccination, and rebuild trust in vaccination programs. A multifaceted approach is required to bridge these gaps, integrating policy reforms, inclusive health communication strategies, and equitable vaccine access. These measures aim to promote awareness and increase vaccination uptake among males in China, ultimately contributing to more comprehensive and equitable public health outcomes.

Analysis of factors influencing HPV vaccination intention among Chinese college students: structural equation modeling based on health belief theory

Background

Increasing human papillomavirus (HPV) vaccination rates is vital for achieving society-wide public health goals, yet current research on HPV vaccine-related knowledge, vaccination intentions, and behaviors among college students in ethnic minority regions is inadequate. This investigation sought to explore the present circumstances of college students in China's ethnic minority regions concerning their awareness, attitudes, and practices related to the HPV vaccine. This study also aimed to provide a scientific basis for future health education and HPV vaccine promotion in China's college student population.

Methods

Based on health belief theory, 1,388 valid questionnaires were collected online to investigate college students' knowledge, beliefs, and behaviors related to HPV vaccination and the factors influencing their willingness to be vaccinated. The data were analyzed via SPSS 26.0 for descriptive analysis and Amos 24.0 for structural equation modeling, factor analysis and path analysis.

Results

The overall HPV vaccine awareness rate was 77.9%. In terms of health attitudes, the positive intention rate was 50.4%, with females having more positive attitudes than males (OR = 2.242, 95% CI = 1.777-2.829). In terms of health behaviors, the rate of positive behaviors was low (40.0%), and the probability of positive behaviors was significantly lower for students with nonmedical-related majors than for those with medical majors (OR = 0.579, 95% CI = 0.442-0.759). The results of the structural equation modeling analysis revealed that college students' perceptions of the perceived benefits of the HPV vaccine positively and directly affect their willingness to be vaccinated (β = 0.290, p < 0.001), and perceived severity has an indirect effect on their willingness to be vaccinated (β = 0.198, p < 0.05).

Conclusion

Although college students in ethnic minority areas have a high rate of HPV-related knowledge, their willingness to be actively vaccinated and their positive behaviors need to be improved. In addition, enhancing the levels of perceived severity and perceived efficacy among college students can help increase their willingness to receive the HPV vaccine.

The impact of vaccine access difficulties on HPV vaccine intention and uptake among female university students in China

BACKGROUND

Ensuring vaccine access is a prerequisite for promoting human papilloma virus (HPV) vaccination. Although HPV vaccination efforts in China have primarily focused on young females, little research has examined the difficulties they face in accessing the HPV vaccine and its impact on vaccine uptake and intention. This study analyzed the overall perception of access difficulties to HPV vaccines, as well as three specific vaccine access difficulties, and examined their influencing factors among female university students in China. We also examined the associations between overall and specific vaccine access difficulties and HPV vaccination intention and uptake.

METHODS

A cross-sectional study was conducted among female university students from eight universities or colleges in Zhejiang Province, China, from December 2020 to January 2021. Logistic regressions were used to identify factors associated with both overall and specific perceptions of vaccine access difficulties. A multivariable logistic regression model and a multiple linear regression model were used to explore factors influencing HPV vaccine uptake and vaccine intention by controlling for potential confounding factors, respectively.

RESULTS

A total of 3176 female university students were included in this study. The proportion of female students perceiving overall difficulty in obtaining HPV vaccine, as well as difficulties in accessing the desired type of HPV vaccine, HPV vaccination centers, and HPV vaccination information, were 60.6%, 57.7%, 60.7%, and 54.0%, respectively. Perceived overall difficulty in obtaining HPV vaccine, as well as difficulties in accessing the desired type of HPV vaccine, HPV vaccination centers, and HPV vaccination information were associated with HPV vaccine uptake and intention.

CONCLUSIONS

Chinese female university students generally perceived various difficulties in accessing HPV vaccine. It is crucial to improve access to HPV vaccine, optimize the layout and service quality of HPV vaccination centers, and enhance the dissemination and transparency of HPV vaccine information. More efforts are needed to provide a strong guarantee for HPV vaccination uptake among female university students.

Factors associated with HPV vaccine hesitancy among college students: A cross-sectional survey based on 3Cs and structural equation model in China

Despite the high effectiveness of HPV vaccines in preventing infection, vaccine hesitancy remains a concern, particularly in China. This study aimed to explore college students' attitudes toward HPV vaccination and identify associated factors. Data was collected through a cross-sectional survey using self-administered questionnaires in four cities from May to June 2022. Chi-square tests and logistic regression analyses were conducted to identify factors. Additionally, an integrated structural equation model (SEM) based on the 3Cs (confidence, convenience, complacency) was developed to understand underlying factors contributing to hesitancy. The results from 2261 valid questionnaires were enlightening. A significant 89.47% (59.4% for females) considered HPV vaccination necessary, with 9.82% remaining neutral and only 0.71% deeming it unnecessary. Factors like higher education, being a medical student, residing in urban areas, having medical insurance, more extraordinary living expenses, a family history of tumors, and a solid understanding of HPV played a role in perceiving the vaccine as necessary. Among the 1438 female respondents, 84.36% had no hesitancy toward HPV vaccination, 13.53% expressed hesitancy, and 2.11% refused vaccination. Factors like age, understanding of HPV, medical staff recommendations, living expenses, and family history influenced hesitancy levels. SEM revealed that the 3Cs significantly affected vaccine hesitancy. Factors like price, booking process, vaccination times, trust in vaccines, medical staff recommendations, efficiency, and risk perception collectively influenced hesitancy. In conclusion, this study found high acceptance of HPV vaccination but acknowledged the complexity of hesitancy factors. It recommends medical staff disseminate scientific knowledge, offer recommendations, simplify booking procedures, and expand vaccination sites to address vaccine hesitancy effectively.

Knowledge, awareness, and correlates of HPV vaccine acceptability among male junior high school students in Zhejiang Province, China

This study assessed the knowledge of 12- to 15-year-old male junior high school students of HPV and HPV vaccines and their willingness to be vaccinated against it. From March to May 2023, students from six junior high schools in Zhejiang Province were randomly selected to complete an online, anonymous, self-administered questionnaire. Of the 1786 students, 618 (34.6%) reported knowledge of HPV vaccine. In general, junior high school boys have low general knowledge about HPV, the consequences of HPV infection, and the effects of HPV vaccination. Multivariate analysis showed that the subgroup scoring 6-7 on the measure of the consequences of HPV infection(7 questions with 1 score for each correct answer) compared to the subgroup scoring 0, the subgroups scoring 2 and 3 on the measure of the preventive effect of HPV vaccine(3 questions with 1 score for each correct answer) compared to the subgroup scoring 0 were were more likely to be willing to be vaccinated against HPV. Hearing that someone close to them had cancer, believing that men also need to be vaccinated against HPV, knowing that someone close to them had been vaccinated against HPV, and being concerned about cervical cancer in their female sexual partners were all more likely to generate positive responses. HPV vaccine education for this group of students should emphasize the possibility and consequences of HPV infection in males, along with the importance and benefits of HPV vaccination; actual cases of vaccination in students around them can be used to achieve this goal.

High burden of human papillomavirus infection among men in Guangzhou, South China: Implications for HPV vaccination strategies

The epidemiological and clinical aspects of Human Papillomavirus (HPV) infection in women have been extensively studied. However, there is a lack of information regarding HPV characteristics in males. In this study, we conducted a retrospective and observational study of 3737 consecutive male individuals attending outpatient clinics of Guangdong Women and Children Hospital from 2012 to 2023 in Guangzhou, South China, to determine the age- and genotype-specific prevalence of HPV in men. The results showed the overall prevalence of HPV among men was 42.15% (1575/3737), with variations ranging from 29.55% to 81.31% across distinct diagnostic populations. Low-risk HPV6 (15.47%), HPV11 (8.94%), and high-risk HPV52 (5.51%) were the most common types. The annual HPV prevalence decreased significantly (Z = -3.882, p < .001), ranging from 31.44% to 52.90%. 28.77% (1075/3737) of men manifested infection with a singular HPV type, predominantly identified as a low-risk type. The age-specific distribution of HPV infections revealed distinctive peaks in the < 25 y age group (47.60%, 208/437) and the 40-44 y age group (44.51%, 154/346). Notably, the positive rate of Chlamydia trachomatis was significantly higher among HPV-positive individuals in comparison to HPV-negatives (16.14% vs. 11.25%, p < .05). Our findings reveal a substantial prevalence of HPV infection among outpatient men in Guangzhou, South China. It is recommended to consider the inclusion of HPV vaccination for adolescent males in national immunization schedules, once an adequate supply of vaccines is accessible.

Awareness regarding human papillomavirus and willingness for vaccination among college students with or without medical background in Guizhou Province

This cross-sectional epidemiological study aimed to investigate awareness regarding human papillomavirus (HPV) and willingness for vaccination among college students with or without medical background in Guizhou Province, China. A logistic regression model was used for univariate and multivariate analyses of cognition to determine factors influencing willingness for vaccination. In total, 2,540 questionnaires were collected, of which 2,360 were valid. The medical and nonmedical groups included 737 (31.2%) and 1,623 (68.8%) individuals, respectively. The medical group had heard of HPV and its vaccines more frequently than the nonmedical group, with the former also having greater awareness than the latter (P < .001). Females (1,325, 56.1%) had heard of HPV and its vaccines more frequently than males (1,035, 43.9%), with the former also having greater awareness than the latter. The cost, safety, and efficacy of the HPV vaccine and lack of knowledge regarding HPV and its vaccines were the main barriers for vaccination. The overall level of knowledge regarding HPV and its vaccines was lower in the nonmedical group and males than in the medical group and females. To help promote willingness for vaccination among the nonmedical group and males, strategies that deepen their knowledge regarding the HPV vaccine are needed.

Trends in the Disease Burden and Risk Factors of Women's Cancers in China From 1990 to 2019

Objectives

To examine age-specific trends and risk factors in the burden of women's cancers (WCs) in China from 1990 to 2019 to inform strategies.

Methods

Data were sourced from the Global Burden of Disease 2019 and World Population Prospects 2019. Time trends, age differences, and key factors for breast, cervical, and ovarian cancers (BC, CC, and OC) were analyzed based on age-standardized incidence rate (ASIR) and disability-adjusted life years (DALYs) rate.

Results

ASIRs for BC and CC increased over the study period, with a slower growth rate for CC after 2005, likely due to targeted HPV prevention. OC showed the highest ASIR and DALY increases, indicating a growing concern. Peak ASIR for BC and CC was in women aged 50-55, while OC showed a higher burden in women aged 70-79. Lower DALYs in women born after 1985 suggest improved healthcare access.

Conclusion

This study highlights significant trends in cancer burden among Chinese women, driven by age and reproductive health policies. Future efforts should enhance screening, health literacy, and age-targeted risk reduction for specific cancer types.

Attitude Towards Vaccination Among University Students at a Spanish University: Relationships with Sociodemographic and Academic Variables

OBJECTIVES

This descriptive, cross-sectional study examines the attitude towards vaccination of students at the Complutense University of Madrid (Spain) and explores its relationship with sociodemographic and academic variables using a bivariate analysis and linear and logistic regression.

METHODS

The attitude towards vaccination of 3577 students of different disciplines was assessed using an online version of the Questionnaire on Attitudes and Behaviours towards Vaccination. In addition, all students were asked if they sought information produced by anti-vaccination groups and whether they identified as "anti-vaccine".

RESULTS

In general, the students showed a favourable attitude towards vaccination. Older students, those in paid employment, and those undertaking non-health-related studies had less favourable attitudes. Spanish-born and female students showed more positive attitudes than foreign-born and non-binary/male students, respectively. Only a small proportion of students identified as anti-vaccine.

CONCLUSIONS

Despite these positive results, the need for interventions targeting specific groups with less favourable attitudes, such as older students, employed students, and those in non-health-related fields, is clear.

Influential factors and willingness to advocate for HPV vaccination among male nursing interns in China

BACKGROUND

Human papillomavirus (HPV) infection significantly contributes to the global cancer burden. Understanding the factors influencing male clinical interns' willingness to promote HPV vaccination is crucial for developing effective public health strategies in China.

METHODS

This study employed a stratified random sampling method to select 1,980 male clinical interns from five provinces in China between January and March 2024. Data were collected on participants' demographic characteristics, HPV-related clinical experience, and knowledge. The Theory of Planned Behavior framework, encompassing attitudes, subjective norms, and perceived behavioral control, was used to examine factors influencing the willingness to promote the HPV vaccine. Logistic regression analyses were conducted to identify factors associated with the willingness to promote the HPV vaccine.

RESULTS

Among the respondents, 72.29% were willing to encourage others to receive the HPV vaccine. Significant factors influencing this willingness included older age (OR = 3.065, P ≤ 0.001), higher monthly household income (OR = 1.449, P = 0.025), participation in the diagnosis and treatment of HPV-related diseases (OR = 3.458, P ≤ 0.001), positive attitude towards the vaccine (OR = 13.503, P = 0.004), and strong perceived behavioral control (OR = 2.364, P = 0.006).

CONCLUSION

This study highlights the critical role of practical experience and targeted education in promoting HPV vaccination among male clinical interns in China. Enhancing the training and education of this group is essential for improving HPV vaccine advocacy and supporting public health efforts to reduce HPV-related diseases.

The role of personal health beliefs and altruistic beliefs in young Chinese adult men's acceptance of the human papillomavirus vaccine

Administering the human papillomavirus (HPV) vaccine to men offers substantial health benefits for both themselves and their female partners. In mainland China, the HPV vaccine has not been approved for men, and little is known about their acceptance of it. This study aims to assess the acceptability of HPV vaccine among young Chinese adult men and examine the association between personal health beliefs, altruistic beliefs, and HPV vaccination intentions and behavioral attempts. A cross-sectional study was conducted among male university students using a multistage cluster sampling method in eight universities across five districts in Zhejiang Province, China. Data were collected from December 2020 to January 2021 using a self-administered, anonymous online questionnaire. Of the 1937 participants, 1009 who had heard of the HPV vaccine completed the questionnaire. Over one-third (40.4%, 408/1009) had high levels of HPV and HPV vaccine knowledge. A total of 695 of 1009 (68.9%) expressed an intention to receive the HPV vaccine when available, and 329 of 1009 (32.6%) had proactively inquired about male HPV vaccination. Perceived susceptibility, perceived benefits, perceived gender barriers, and perceived benefits of male HPV vaccination for female partner were associated with HPV vaccination intentions. Lower perceived vaccine barriers, greater perceived benefits, and stronger vaccination intentions were associated with higher HPV behavioral attempts. There is an emerging demand for HPV vaccinations among young adult men in mainland China. Personal health beliefs and altruistic beliefs are crucial in promoting young adult men's acceptance of the HPV vaccine. Emphasizing both male-specific benefits and altruistic motivations may enhance HPV vaccine acceptability among young adult men.

Human papillomavirus vaccination intention and its associated factors among female medical college students in Hubei, China: A cross-sectional study

BACKGROUND

The uptake rate of human papillomavirus (HPV) vaccination in China is low, including among college students. In addition, medical students are the target population for the HPV vaccine, but they have poor uptake of the HPV vaccine. This study aimed to investigate factors related to HPV vaccination intention among female medical college students in Hubei Province.

MATERIALS AND METHODS

This cross-sectional study was conducted on 988 female medical college students from six colleges in Hubei Province with a multistage sampling method. The data were collected by web-based online software. Multiple logistic regression was applied to explore the factors associated with the intention of HPV vaccination.

RESULTS

The majority of students (85.5%) reported a high level of intention to receive HPV vaccine, about 82.3% have a willingness to pay (WTP) for HPV vaccine, and 51.5% reported that family members had never received the HPV vaccine. The students who had higher scores of knowledge of HPV, HPV infection prevention awareness, the protection motivation theory (PMT)-related factors including perceived severity, perceived response efficacy, perceived self-efficacy, and WTP for the HPV vaccine had higher intention to receive HPV vaccine.

CONCLUSION

HPV vaccination intention was high in medical students. Also, it was influenced by knowledge of HPV, PMT-related factors, and WTP for HPV vaccine. Thus, consideration of these factors is important to design the HPV vaccination campaign that can increase the intention to receive HPV vaccine, which in turn may increase the HPV vaccination.

Analyzing HPV Vaccination Service Preferences among Female University Students in China: A Discrete Choice Experiment

OBJECTIVE

Despite being primary beneficiaries of human papillomavirus (HPV) vaccines, female university students in China exhibit low vaccination rates. This study aimed to assess their preferences for HPV vaccination services and evaluate the relative importance of various factors to inform vaccination strategy development.

METHODS

Through a literature review and expert consultations, we identified five key attributes for study: effectiveness, protection duration, waiting time, distance, and out-of-pocket (OOP) payment. A D-efficient design was used to create a discrete choice experiment (DCE) questionnaire. We collected data via face-to-face interviews and online surveys from female students across seven universities in China, employing mixed logit and latent class logit models to analyze the data. The predicted uptake and compensating variation (CV) were used to compare different vaccination service scenarios.

RESULTS

From 1178 valid questionnaires, with an effective response rate of 92.9%, we found that effectiveness was the most significant factor influencing vaccination preference, followed by protection duration, OOP payment and waiting time, with less concern for distance. The preferred services included a 90% effective vaccine, lifetime protection, a waiting time of less than three months, a travel time of more than 60 min, and low OOP payment. Significant variability in preferences across different vaccination service scenarios was observed, affecting potential market shares. The CV analysis showed female students were willing to spend approximately CNY 5612.79 to include a hypothetical 'Service 5' (a vaccine with higher valency than the nine-valent HPV vaccine) in their prevention options.

CONCLUSIONS

The findings underscore the need for personalized, need-based HPV vaccination services that cater specifically to the preferences of female university students to increase vaccination uptake and protect their health.

Attitudes toward an HPV vaccine for condyloma acuminata and willingness to undergo vaccination among STD clinic attendees in China: Focus on STI prevention with HPV vaccine

BACKGROUND

Condyloma acuminata (CA) is a common, and recurrent sexually transmitted disease (STD) that greatly contributes to direct health care costs and has a substantial psychosocial impact. Human papillomavirus (HPV) vaccination (containing L1 protein for HPV types 6 and 11) effectively controls CA.

OBJECTIVES

We investigated attitudes toward the HPV vaccine for CA and willingness to undergo vaccination among STD clinic attendees in China.

METHODS

Attendees at STD clinics at two selected hospitals in Guangdong and Jiangsu Provinces from May to September 2017 were requested to complete a self-administered questionnaire for this cross-sectional study.

RESULTS

The participants' median age was 28 years (IQR: 24.0-34.0), and the sex ratio was balanced; 63.5% were from Guangdong, 36.5% were from Jiangsu, and 44.5% had a history of CA. The vaccine acceptance rate was high among the participants (85.8%,235/274) to whom the HPV vaccine for CA was available, especially among those who had heard of CA (89.0%, AOR = 3.14, 95% CI: 1.29-7.63, p = 0.0114). 95 (34.7%) of 274 participants had a positive attitude toward the HPV vaccine for CA. STD clinic attendees who had heard of the connection between HPV and CA (AOR = 2.56, 95% CI: 1.31-5.00, p = 0.0060), had heard of the HPV vaccines or cervical cancer vaccines (AOR = 1.90, 95% CI: 1.02-3.54, p = 0.0444) and had ever proactively discussed CA or the vaccine with others (AOR = 1.95, 95% CI:1.00-3.79, p = 0.0488) had better attitudes toward the HPV vaccine for CA. Over half of the participants (52.5%) expected the price of the HPV vaccine for CA to be under $90.

CONCLUSION

The acceptance of the HPV vaccine for CA was high among STD clinic attendees in China, and the participants' self-perceived knowledge of CA and HPV was associated with better attitudes toward the HPV vaccine for CA. Education to improve knowledge is vital for reducing vaccine hesitancy.

Implicit theories of health predict HPV vaccination intention among young adult Chinese women: The mediating effect of consideration of future consequences and future self-continuity

This study investigated the predicting effect of implicit theories of health on HPV vaccination intention among young adult Chinese women and its underlying mechanisms. Four-hundred and eighty-three young Chinese women adults (18-26 years old) participated this study by completing measures on implicit theories of health, consideration of future consequences, future self-continuity, and reported their HPV vaccination intention. The results demonstrated that age, whether they knew someone being diagnosed with cancer, implicit (incremental) theories of health, consideration of future consequences (CFC-Future), and future self-continuity significantly predicted young adult Chinese women's HPV vaccination intention. The predicting effect of implicit theories of health was mediated by consideration of future consequences and future self-continuity. Implications of the current research for promoting HPV vaccination among young adult women and directions for future research are discussed.

Human papillomavirus infection: Epidemiology, biology, host interactions, cancer development, prevention, and therapeutics

Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections worldwide. It is caused by the HPV, a DNA virus that infects epithelial cells in various mucous membranes and skin surfaces. HPV can be categorised into high-risk and low-risk types based on their association with the development of certain cancers. High-risk HPV types, such as HPV-16 and HPV-18, are known to be oncogenic and are strongly associated with the development of cervical, anal, vaginal, vulvar, penile, and oropharyngeal cancers. These types of HPV can persist in the body for an extended period and, in some cases, lead to the formation of precancerous lesions that may progress to cancer if left untreated. Low-risk HPV types, such as HPV-6 and HPV-11, are not typically associated with cancer but can cause benign conditions like genital warts. Genital warts are characterised by the growth of small, cauliflower-like bumps on the genital and anal areas. Although not life-threatening, they can cause discomfort and psychological distress. HPV is primarily transmitted through sexual contact, including vaginal, anal, and oral sex. It can also be transmitted through non-penetrative sexual activities that involve skin-to-skin contact. In addition to sexual transmission, vertical transmission from mother to child during childbirth is possible but relatively rare. Prevention of HPV infection includes vaccination and safe sexual practices. HPV vaccines, such as Gardasil and Cervarix, are highly effective in preventing infection with the most common high-risk HPV types. These vaccines are typically administered to adolescents and young adults before they become sexually active. Safe sexual practices, such as consistent and correct condom use and limiting the number of sexual partners, can also reduce the risk of HPV transmission. Diagnosis of HPV infection can be challenging because the infection is often asymptomatic, especially in men. In women, HPV testing can be done through cervical screening programs, which involve the collection of cervical cells for analysis. Abnormal results may lead to further diagnostic procedures, such as colposcopy or biopsy, to detect precancerous or cancerous changes. Overall, HPV infection is a prevalent sexually transmitted infection with significant implications for public health. Vaccination, regular screening, and early treatment of precancerous lesions are key strategies to reduce the burden of HPV-related diseases and their associated complications. Education and awareness about HPV and its prevention are crucial in promoting optimal sexual health. This study aimed to carry out a literature review considering several aspects involving HPV infection: Global distribution, prevalence, biology, host interactions, cancer development, prevention, therapeutics, coinfection with other viruses, coinfection with bacteria, association with head and neck squamous cell carcinomas, and association with anal cancer.

Human papillomavirus vaccination and contributing factors of vaccination intention among adolescents and young adults in China from a socio-ecological perspective: A cross-sectional study

OBJECTIVES

Adolescents and young adults are the main target population for human papillomavirus (HPV). The study aimed to investigate school students' HPV vaccination intentions and explore the contributing factors from a socio-ecological perspective.

DESIGN

A questionnaire survey was conducted in three secondary schools and three colleges in China.

SAMPLE

A total of 1756 students aged 14-22 years participated in this study. Among the 1756 participants, 182 students have received the HPV vaccine. For the remaining 1574 students, we analyzed their HPV vaccination intentions and the influencing factors.

MEASUREMENTS

Survey items for sociodemographics, knowledge and awareness of HPV, sexual intercourse and sexual knowledge, subjective socioeconomic status, self-efficacy, eHealth literacy, perceived social support from family, and the availability of HPV vaccine information were measured.

RESULTS

Only 182 (10.4%) had received the HPV vaccine among the 1756 participants. Among the remaining 1574 students, the majority of the students (1403, 89.1%) were willing to receive the HPV vaccine. Binary logistic regression analysis showed that students who were female, had lower self-efficacy, scored higher on sexual knowledge, believed vaccination preventing related diseases, worried about side effects after vaccination, thought oneself at risk of contracting HPV, had higher family support, knew the availability of the HPV vaccine in Mainland China from healthcare institutions, and with family residence in rural areas were more willing to receive the HPV vaccine.

CONCLUSIONS

Students had high HPV vaccination intentions while had low vaccination rate. Intrapersonal, interpersonal and institutional or community factors predicted HPV vaccination intention. Public health nurses in communities and schools could target the modifiable factors to promote students' HPV vaccine uptake.

Enhancing Human Papillomavirus Vaccination Rates through Better Knowledge? Insights from a Survey among German Medical Students

INTRODUCTION

Vaccination against human papillomavirus (HPV) significantly reduces the risk for malignant diseases like cervix, anal, or penile cancer. However, although vaccination rates are rising, they are still too low mirroring a lack of disease awareness in the community. This study aims to evaluate knowledge about HPV vaccination as well as the vaccination rate among German medical students.

MATERIAL AND METHODS

Medical students were surveyed during a German medical students' sports event. The self-designed survey on HPV vaccination consisted of 24 items. The data collection was anonymous.

RESULTS

Among 974 participating medical students 64.9% (632) were women, 335 (34.4%) were male and 7 (0.7%) were nonbinary. Mean age was 23.1 ± 2.7 (± standard deviation; range 18-35) years. Respondents had studied mean 6.6 ± 3.3 (1-16) semesters and 39.4% (383) had completed medical education in urology. 613 (64%) respondents reported that HPV had been discussed during their studies. 7.6% (74) had never heard of HPV. In a multivariate model female gender, the knowledge about HPV, and having worked on the topic were significantly associated with being HPV-vaccinated. Older students were vaccinated less likely.

CONCLUSIONS

Better knowledge and having worked on the topic of HPV were associated with a higher vaccination rate. However, even in this highly selected group the knowledge about HPV vaccination was low. Consequently, more information and awareness campaigns on HPV vaccination are needed in Germany to increase vaccination rates.

A survey of potential acceptance of 9-valent HPV vaccine among Chinese male college students

Human papillomavirus (HPV) has a great impact on world health. Vaccination is among the most important methods of preventing HPV infection. This study investigated Chinese male college students' knowledge of, attitude toward, and acceptance of the 9vHPV vaccine and the independent predictors. An online cross-sectional study was conducted among male college students at Chinese colleges and universities from March 12 to March 23, 2022. Based on a literature review of similar studies, a self-questionnaire was designed to investigate the students' knowledge of, attitude toward, and acceptance of the 9vHPV vaccine. Multivariate logistic regression analysis was performed to identify factors influencing their willingness to be vaccinated. In addition, the structural equation model was constructed. A total of 1,547 male college students completed the survey. Of all the students, 54.95% were unwilling to receive a 9vHPV vaccination, while only 45.05% expressed willingness. Multivariate logistic regression analysis revealed that the male college students willing to receive the vaccine included medical students, those in a romantic relationship, those whose relatives and friends had cervical cancer, those whose relatives and friends had received the 9vHPV vaccine, those supportive of promoting the vaccine for men, and those who would recommend the vaccine to their relatives and friends. Male college students exhibited high hesitancy toward the 9vHPV vaccine. Acceptance of the 9vHPV vaccine by male college students can be improved by deepening their accurate understanding of the vaccine and enhancing their positive attitude toward it.

HPV Infection Profiles among People Living with HIV and HPV Vaccine Acceptance among Individuals with Different HIV Infection Statuses in China: A Systematic Meta-Analysis

To understand the HPV infection profiles among Chinese HIV/AIDS patients and the HPV vaccine acceptance among unvaccinated Chinese people with different HIV infection statuses after the HPV vaccine launch in China, this study searched Web of Science, PubMed, Cochrane Library, Embase, Scopus, CNKI, WANFANG, SinoMed, and VIP databases up to 23 June 2023, according to the registered protocol (CRD42023449913). A total of 58 studies were included. The results showed that the HPV infection rate among Chinese HIV/AIDS patients was 52.54% (95% CI: 42.11-62.86%) and higher in males than in females (74.55% vs. 41.04%); meanwhile, the rate was higher in the anus than in the cervix (69.22% vs. 41.71%). Although there was no statistical difference, the high-risk HPV infection rate (38.98%) was higher than low-risk HPV (23.86%), and single infections were more common (28.84%) than multiple infections (19.23%). HPV vaccine acceptance among the unvaccinated Chinese population was 59.19% (95% CI: 52.50-65.89%), and was slightly higher among HIV-infected rather than non-HIV-infected individuals (67.72% vs. 59.58%). There was a difference in acceptance among respondents from different regions. Although the difference in acceptance rate between males and females was not statistically significant (61.10% vs. 61.18%), MSM had a higher acceptance rate than non-MSM (84.28% vs. 59.05%). HPV infection is prevalent among HIV patients, demonstrating the need to increase the frequency of HPV screening for PLWH. The HPV vaccine acceptance rate is higher than that of non-HIV-infected individuals. Male acceptance is almost the same as female's, with MSM acceptance higher than non-MSM, suggesting that using MSM, especially MSM in PLWH, as an entry point may be a practical avenue to explore to further expand the scope of HPV vaccination.

Evaluating Knowledge, Attitudes, and Behaviors toward HPV Infection and Vaccination among University Students in Italy

BACKGROUND

This survey investigated the knowledge, attitudes, and behaviors towards HPV preventive measures among university students in Italy and their associated factors.

METHODS

The cross-sectional survey was conducted between November 2022 and April 2023.

RESULTS

Only 41.7% knew about HPV infection and the main preventive measures. Multilevel mixed-effects logistic regression analysis showed that females, those aged 25-30 years, those who have had oral sex, those who had received information about HPV infection and preventive measures from physicians, and those who needed additional information about HPV infection and preventive measures were more knowledgeable. Only 39.1% have received at least one HPV vaccination dose, whereas 29.2% and 31.7% had not been vaccinated or did not remember. Multilevel mixed-effects logistic regression analysis identified that female students enrolled in the field of health sciences, those who did not report a prior history of a sexually transmitted infection, and those with a higher knowledge about HPV infection and preventive measures were more willing to receive the HPV vaccination.

CONCLUSIONS

Despite some limitations, this was the first detailed survey on this topic conducted in the post-acute phase of COVID-19 among university students in Italy. The survey underlined the need to develop and to implement comprehensive educational programs and health interventions among students, to enhance their knowledge and modify their attitudes and improve the HPV vaccine uptake.

Knowledge and perceptions regarding Human Papillomavirus (HPV) and willingness to receive HPV vaccination among university students in a north-eastern city in Turkey

BACKGROUND

For a HPV vaccination program to be successful, it is important that the target population has sufficient knowledge about HPV and HPV vaccines. The aim of this study was to evaluate HPV-related knowledge levels among students at a university in northern Turkey, to assess vaccination willingness, and to determine factors associated with HPV-related knowledge.

METHODS

This cross-sectional study was conducted on 824 (93.1%) students studying at 16 different faculties. The study population was identified through the proportional stratified sampling method. Data were collected through a questionnaire including socio-demographic characteristics and the HPV Knowledge Scale. Multiple linear regression analysis was performed to identify factors that may be associated with knowledge scores.

RESULTS

43.6% of the students had never heard of HPV, 50.6% of them had never heard of HPV screening tests or HPV vaccination. Only 2.7% of the students were vaccinated against HPV and 15.7% were willing to receive HPV vaccination. Awareness of HPV and willingness to receive vaccination were found to be higher among women, while previous experience with sexual intercourse was higher in men (p < 0.05). The mean HPV knowledge score was quite low (6.74 ± 7.13 out of 29 points). The studying in a field related to health sciences, being a senior student, intending to be vaccinated, being a woman, having had sex were found to be associated with high knowledge levels (p < 0.05).

CONCLUSIONS

Educational programmes should be developed to increase university students' knowledge about HPV and the HPV vaccine.

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.

Factors Associated with Commercial Sex Behavior among Male College Students Who Engaged in Temporary Heterosexual Behavior in Zhejiang Province, China

Objective

This study explored the characteristics and associated factors of commercial sex behavior among male college students who engaged in temporary heterosexual behaviors in Zhejiang Province, China.

Methods

The participants were male college students with temporary heterosexual behaviors. We developed an online questionnaire to collect information on demographic characteristics, sexual attitudes, sexual behaviors, and HIV/AIDS interventions through stratified cluster sampling. Chi-square (χ ²) tests were performed for the different groups of participants. The occurrence of commercial sex behavior among participants was taken as the dependent variable, and logistic regression was used to analyze the factors associated with the participants' commercial sex behavior.

Results

This study investigated the temporary heterosexual behavior of 424 male college students. Among them were 112 students who reported commercial sex behavior (26.42%), whose average age was 20.25 ± 1.27 years, and whose household registration of Zhejiang Province accounted for 63.39%. The results of the multivariate logistic regression analysis indicated that acceptance of commercial sex behavior (Adjusted (a) OR = 3.53, 95% CI = 1.94~6.40) and feeling at risk of contracting HIV (aOR = 6.44, 95% CI = 2.98~13.94), seeking temporary sexual partners through the Internet (aOR = 2.58, 95% CI = 1.27~5.25), consistently using condoms during sex (aOR = 0.34, 95% CI = 0.16~0.70), or using condoms sometimes/frequently during sex (aOR = 0.30, 95% CI = 0.13~0.68) were independent factors associated with male college students with temporary heterosexual behavior engaging in commercial sex behavior.

Conclusion

Open sexual attitudes, seeking temporary sexual partners through the Internet, high awareness of HIV infection risk, and low condom use are associated factors for male college students engaging in commercial sex behavior. For college students' HIV/AIDS prevention and education interventions, it is necessary to strengthen the prevention of network influence, increase peer education, increase teacher participation in education, enhance college students' risk awareness, advocate for the use of condoms, and promote HIV/AIDS prevention and treatment.

Factors Influencing Men’s Attitudes toward HPV Vaccination in Males Included in the Chinese National Immunization Program

Background: Human papillomavirus (HPV) infection is the most common sexually transmitted disease, and it is associated with anogenital warts and oropharyngeal and anogenital cancers. Among female malignant tumors in China, the incidence of cervical cancer ranks second, with only breast cancer being more prevalent. HPV infection and related diseases affects both women and men. HPV vaccination is an optimal prevention strategy in preventing HPV infection and related diseases. The inclusion of the HPV vaccine in the national immunization program is an effective way to increase immunization coverage, reduce the burden of HPV related diseases, and increase national life expectancy. Objective: This study aimed to explore the factors influencing the attitudes of Chinese men toward the inclusion of the HPV vaccine in males included in the national immunization program, thus providing reference for launching the national immunization program policy. Methods: We invited men aged 20 to 45 to participate in an online survey. The participants were requested to complete a questionnaire, including sociodemographic characteristics, sexual behavior characteristics, knowledge of HPV and the HPV vaccine, and attitudes toward the HPV vaccine. A logistic regression model was constructed to analyze the influencing factors of attitudes. Results: A total of 660 males in China participated in this survey, and 80.45% supported the inclusion of HPV vaccines in national immunization programs. Participants earning CNY 100,000–200,000 (dds ratio (OR): 0.63, 95% confidence interval (CI): 0.39–1.00) or ≥200,000 (OR: 0.34, 95% CI: 0.17–0.68) were more likely to disapprove this strategy. Compared with people without a history of HPV infection, those with a history of HPV infection (OR: 1.84, 95% CI: 1.17–2.90) were more likely to approve. Men who had better knowledge of HPV were more likely to approve than men with less knowledge about HPV (OR: 1.44, 95% CI: 1.17–1.79). Compared with participants who did not know when the HPV vaccine should be given, those who knew that the ideal time of vaccination is before an individual becomes sexually active (OR: 1.75, 95% CI: 1.04–2.95) were more likely to approve. Conclusion: One in five men did not support the inclusion of HPV vaccines in national immunization programs, and they are likely to be from higher socioeconomic background and have poor knowledge of HPV. In order to implement comprehensive immunity, targeted actions need to be taken at national and public levels. In addition, when implementing measures, more attention needs to be paid to lower income men, men without a history of HPV infection and with poor knowledge of HPV, as well as young men.
