[PMID: 38977424 PMCID: PMC11232639 DOI: 10.1080/21645515.2024.2372883] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Accepted: 06/23/2024] [Indexed: 07/10/2024] Open
Abstract
Multiple studies have documented low human papillomavirus (HPV) vaccine uptake among Chinese girls. It remains crucial to determine the parental willingness to pay (WTP) HPV vaccine for girls. We conducted a cross-sectional study recruiting 3904 parents with girls aged 9-14 in Shanghai, China, employing an online questionnaire with a convenience sampling strategy. Parental WTP, both range of payment and estimated point value, were determined for themselves (or wives) and daughters. HPV vaccine uptake was 22.44% in mothers and 3.21% in daughters. Respondents favored WTP ≤ 1000 CNY/138 USD for themselves (or wives), whereas showed increasing WTP along with valency of HPV vaccine for daughters (2-valent: 68.62% ≤1000 CNY/138 USD; 4-valent: 56.27% 1001-2000 CNY/138-277 USD; 9-valent: 65.37% ≥2001 CNY/277 USD). Overall, respondents showed higher WTP for daughters (median 2000 CNY/277 USD; IQR 1000-3600 CNY/138-498 USD) than for themselves (2000 CNY/277 USD; 1000-3500 CNY/138-483 USD) or wives (2000 CNY/277 USD; 800-3000 CNY/110-414 USD) (each p < .05). Furthermore, parental WTP was higher for international vaccine and 9-valent vaccine (each p < 0.05). Between two assumed government subsidy scenarios, parental preference for 9-valent vaccine remained consistently high for daughters (approximately 24% in each scenario), whereas preference for themselves (or wives) was sensitive to payment change between the subsidy scenarios. Using a discrete choice experiment, we found domestic vaccine was commonly preferred; however, certain sociodemographic groups preferred multivalent HPV vaccines. In conclusion, the valency of HPV vaccine may influence parental decision-making for daughters, in addition to vaccine price. Our findings would facilitate tailoring the HPV immunization program in China.

Abstract
Objective Providing the human papillomavirus (HPV) vaccine is effective to eliminate the disparity in HPV-related cancers. It is unknown regarding inequality in the distribution of HPV vaccination in China since the vaccine was licensed and approved for use in 2016. This study aimed to examine socioeconomic inequalities in HPV-related knowledge and vaccination and identified factors associated with such inequalities. Methods Self-administered questionnaires measuring HPV-related knowledge and vaccine uptake were completed by 1,306 women through online survey platform. HPV knowledge was assessed using a 12-item question stem that covered the hazards of HPV infection, HPV vaccine dosage, benefits, and protection. Cluster analysis by combining monthly household income, educational level, and employment status was used to identify socioeconomic status (SES) class. The concentration index (CI) was employed as a measure of socioeconomic inequalities in HPV-related knowledge and vaccination. Linear regression and logistic regression were established to decompose the contributions of associated factors to the observed inequalities. Results The CI for HPV-related knowledge and vaccine uptake was 0.0442 and 0.1485, respectively, indicating the higher knowledge and vaccination rate were concentrated in groups with high SES. Education and household income made the largest contribution to these inequalities. Age, residency and cervical cancer screening were also important contributors of observed inequalities. Conclusion Socioeconomic inequalities in HPV-related knowledge and vaccination uptake are evident in China. Interventions to diffuse HPV-related information for disadvantaged groups are helpful to reduce these inequalities. Providing low or no-cost HPV vaccination and ensuring accessibility of vaccines in rural areas are also considered to be beneficial.

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. BMC Public Health 2024; 24:1610. [PMID: 38886680 PMCID: PMC11181624 DOI: 10.1186/s12889-024-18904-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 05/21/2024] [Indexed: 06/20/2024] Open
Abstract
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.

Abstract
Following the approval of Cervarix for the immunization of girls and women in China against high-risk human papillomavirus types 16 and 18, a non-interventional post-authorization safety study was performed. A multi-center prospective cohort study assessed safety following Cervarix vaccination of Chinese girls and women aged 9-45 years between 31 May 2018 and 3 December 2020. Adverse events following immunization (AEFIs), potential immune-mediated diseases (pIMDs), and pregnancy-related outcomes were collected up to 12 months from the third immunization or 24 months from the first immunization, whichever came first. Among 3,013 women who received 8,839 Cervarix doses, 167 (5.5%) reported ≥ 1 any AEFI, and 22 (0.7%) reported 40 serious AEFIs. During the 30 days after each dose, 147 women (4.9%) reported 211 medically attended AEFIs, including 3 serious AEFIs reported by 1 woman (0.03%). One woman reported a pIMD. Cervarix was inadvertently administered to 65 women (2.2%) within 60 days before conception or during pregnancy. Of these women, 34 (52.3%) gave birth to live infant(s) with no apparent congenital anomalies, and 1 (1.5%) woman gave birth to a live infant with a congenital anomaly. No serious AEFIs or pIMDs were considered to be related to the vaccination. In Chinese women aged 9-45 years, immunization with the Cervarix three-dose schedule was well tolerated. Overall, no safety concerns were identified, although rare adverse events may have been missed due to the study sample size.Clinical trial registration: NCT03438006.

Implementing the free HPV vaccination for adolescent girls aged below 14 in Shenzhen, Guangdong Province of China: experience, challenges, and lessons. Infect Dis Poverty 2023; 12:98. [PMID: 37899444 PMCID: PMC10614323 DOI: 10.1186/s40249-023-01149-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Accepted: 10/10/2023] [Indexed: 10/31/2023] Open
Abstract
Cervical cancer is a major public health concern in China, accounting for almost one-fifth of the global incidence and mortality. The recently prequalified domestic bivalent human papillomavirus (HPV) vaccine offers a practical and feasible preventive measure. In response to the global call for action, the National Health Commission issued an Action Plan to eliminate cervical cancer by 2030, with promotion of the HPV vaccination for school-aged girls as a critical step. Despite this, implementation of the vaccination has been patchy, with very low coverage among eligible girls. To address this, from December 2021 to December 2022, a demonstration project was launched in Shenzhen, Guangdong Province, to promote the inclusion of HPV vaccine in local immunisation programme and to address existing barriers to implementation. Using multiple sources of data, this article presents a case study of the demonstration project, analysing its impact on rolling out HPV vaccination among eligible girls and identifying any challenges encountered during implementation. The demonstration project has shown promising results in increasing the HPV vaccination rate, promoting public awareness and acceptance of the domestic HPV vaccine, and establishing a model for quickly scaling up the vaccination at the municipal level. The success of the project can be attributed to several factors, including strong governmental commitment, sufficient funding, multi-sectoral collaboration, ensured vaccine accessibility and affordability, improved vaccination services, and effective health education and communication strategies. Lessons learned from Shenzhen can provide valuable insights for future advocacy and implementation of the vaccination in other areas of China, but challenges must be addressed to achieve universal coverage. These include addressing vaccine hesitancy, expanding the programme to cover a broader age range, and ensuring consistent quality of vaccination services in primary care facilities. Overcoming these challenges will require innovative strategies, public-private partnerships, and sustained funding and resources. Future research should focus on evaluating the long-term effectiveness of the vaccination programme and identifying contextual factors that may impact its implementation in different settings. Overall, the effective control of cervical cancer in China will rely on the "political will" to ensure the incorporation of preventive interventions into policies and universal programme coverage.

Abstract
The high prevalence of human papillomavirus (HPV) infection in China suggests there would be a substantial positive health impact of widespread vaccination against HPV. We adapted a previously described dynamic transmission model of the natural history of HPV infection and related diseases to the Chinese setting to estimate the public health impact in China of 2-valent (with and without cross-protection), 4-valent, and 9-valent HPV vaccination strategies. The model predicted the incidence and mortality associated with HPV-related diseases, including cervical and noncervical cancers, genital warts, and recurrent respiratory papillomatosis (RRP), based on the various vaccination coverage rate (VCR) scenarios, over a 100-year time horizon. The public health impact of the 4 vaccination strategies was estimated in terms of cases and deaths averted compared to a scenario with no vaccination. Under the assumption of various primary and catch-up VCR scenarios, all 4 vaccination strategies reduced the incidence of cervical cancer in females and noncervical cancers in both sexes, and the 4-valent and 9-valent vaccines reduced the incidence of genital warts and RRP in both sexes. The 9-valent vaccination strategy was superior on all outcomes. The number of cervical cancer cases averted over 100 years ranged from ~ 1 million to ~ 5 million while the number of cervical cancer deaths averted was ~ 345,000 to ~ 1.9 million cases, depending on the VCR scenario. The VCR for primary vaccination was the major driver of cases averted.

Abstract
BACKGROUND This study was conducted to characterize the long-term effect of mobile-based education on Chinese female freshmen and disclose the possible predictors of their willingness to get vaccinated based on the information-motivation-behavioral skills (IMB) model. METHODS We randomly assigned 509 participants to a 7-day mobile-based educational intervention or control group and collected information about general information, health, and sexual behavior, HPV vaccination intention and action, HPV-related knowledge, cognition, and behavioral skill by an online self-administrated questionnaire at baseline, post-intervention, and at the 1-month and 3-month follow-ups. RESULTS The intervention arm showed an improvement in IMB scores after education. Despite the persistent improvement in knowledge, the improvement in their motivation and behavioral skills decreased at the 1-month and 3-month follow-ups. Participants' vaccination willingness was elevated after the baseline survey in both the intervention and control groups, while the overall appointment/vaccination rate was only 3.73% 3 months later. The intention to get vaccinated was associated with knowing HPV (adjusted OR: 2.37, 95% CI: 1.44 - 3.89), perceiving more barriers (adjusted OR: 2.16, 95% CI: 1.44 - 3.25), higher subjective norms (adjusted OR: 2.05, 95% CI: 1.26 - 3.32), and having more behavioral skills (adjusted OR: 2.95, 95% CI: 1.79 - 4.87). CONCLUSION Seven-day mobile-based education was effective to increase IMB model scores among female freshmen. However, the improvement in motivation and behavioral skills was not persistent. Information, perceived barriers, subjective norms, and behavioral skills were discovered to be influencing factors of vaccination intention. Future research with longer, more convenient, and more tailored education to the main influencing factors is warranted.

Abstract
Human papillomavirus (HPV) vaccine uptake remains low in China, especially among girls. Recently, China has initiated a pilot program on HPV immunization for girls aged 9-14 years. We conducted a cross-sectional online survey in Minhang district of Shanghai, a pilot region for the program, to investigate HPV vaccination status among mothers and their daughters 9-14. A total of 1031 parents and 1122 daughters 9-14 were included. Of them, 18.6% of mothers and 4.5% of daughters had been vaccinated with HPV vaccines or made an appointment; additionally, 62.7% and 78.4% intended to receive vaccination but did not make an appointment. Notably, 6.2% of parents did not intend to receive vaccination for themselves (or their wives) but intended to vaccinate their daughters. Moreover, we calculated parental knowledge and awareness scores toward HPV infection and vaccination. Both scores were significantly higher among the parents who had received HPV vaccination than those who intended to across mothers' vaccination status (P < .001 for knowledge and P = .019 for awareness), whereas similar between the two groups across daughters' vaccination status (P = .694 and P = .737). Parents believed mothers had a significantly higher susceptibility to HPV infection and lower health consequences, compared to daughters 9-12 (P = .002 and P < .001) or those 13-14 (both P < .001). In conclusion, HPV vaccine uptake remains a discrepancy between mothers and their daughters 9-14. However, their intents to receive HPV vaccination were both high. Parental knowledge and awareness may improve vaccination intent for daughters 9-14 in China. It warrants a certain health education toward susceptibility to HPV infection and health consequences.

Abstract
Background In order to increase HPV vaccination, it is necessary to identify the factors influencing vaccination behavior among different cultures and the young adult populations. To evaluate the factors influencing HPV vaccine uptake behaviors, valid, reliable, and culture-compatible scales are required. This study was conducted with the aim of designing and psychometric assessment of the scale of factors influencing HPV vaccine uptake behaviors in Young Adults (FI(HPV)VUBYA) in Iran. Methods The present study was carried out in a mixed-method in two steps: (a) Generating items using a qualitative study and literature review and (b) Reducing items by psychometric assessment of the designed scale. The initial set of items (N = 80) was prepared based on a qualitative study and literature review. A total of 400 young adults participated in online data collection from November 2019 to February 2020. The validity (face, content, and construct) and reliability (internal consistency and stability) of the scale were evaluated. Results The exploratory factor analysis (EFA) revealed that the scale has 7 factors, explaining 57.84% of the total extracted variance. There was also a knowledge factor that EFA did not analyze, but its validity and reliability were evaluated with 7 other factors. The results of confirmatory factor analysis showed a good model fit. Convergent and divergent validity of the scale was accepted for all factors. Good reliability was also reported for the scale. Conclusion FI(HPV)VUBYA 8-factor scale has good validity and reliability among young Iranian adults. Due to its appropriate psychometric properties, this scale can be used on this population in future studies.

Abstract
Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. The HPV vaccination has been widely advocated around the world since the vaccine is beneficial in avoiding diseases, including some sexually transmitted diseases, brought on by HPV infections. For most Chinese, the HPV vaccine is still a relatively new concept, having only been made available to the general public in 2016. Despite the vaccine's increased prominence, there is still a lack of investigation about how the public is influencing the conversation about HPV vaccines and the public's perception of this vaccine. With the theoretical construct of the Health Belief Model, this study conducts both quantitative and qualitative content analysis to investigate the existing media narratives around HPV vaccines in China and the changes in public opinion by looking at users' contributions on Weibo, one of China's most popular social networking sites. It was found that different groups of Weibo users had contributed to diverse narratives surrounding HPV vaccination. Though the public awareness of HPV vaccination had been improved along with increasingly active communication practices and enhanced public health services, public knowledge about HPV remains inadequate. Therefore, to facilitate the popularisation of HPV related knowledge, more effort should be invested in tailoring and disseminating messages that communicate responsive and comprehensive HPV related information.

Abstract
The World Health Organization (WHO) global strategy to eliminate cervical cancer (CxCa) could result in >62 million lives saved by 2120 if strategy targets are reached and maintained: 90% of adolescent girls receiving prophylactic human papillomavirus (HPV) vaccine, 70% of women receiving twice-lifetime cervical cancer screening, and 90% of cervical pre-cancer lesions and invasive CxCa treated. However, the cost and complexity of CxCa screening and treatment approaches has hampered scale-up, particularly in low- and middle-income countries (LMICs), and new approaches are needed. Therapeutic HPV vaccines (TxV), which could clear persistent high-risk HPV infection and/or cause regression of pre-cancerous lesions, are in early clinical development and might offer one such approach. During October 2021 to March 2022, WHO, in collaboration with the Bill and Melinda Gates Foundation, convened a series of global expert consultations to lay the groundwork for understanding the potential value of TxV in the context of current CxCa prevention efforts and for defining WHO preferred product characteristics (PPCs) for TxV. WHO PPCs describe preferences for vaccine attributes that would help optimize vaccine value and use in meeting the global public health need. This paper reports on the main discussion points and findings from the expert consultations. Experts identified several ways in which TxV might address challenges in current CxCa prevention programmes, but emphasized that the potential value of TxV will depend on their degree of efficacy and how quickly they can be developed and implemented relative to ongoing scale-up of existing interventions. Consultation participants also discussed potential use-cases for TxV, important PPC considerations (e.g., vaccine indications, target populations, and delivery strategies), and critical modelling needs for predicting TxV impact and cost-effectiveness.

Willingness to human papillomavirus (HPV) vaccination and influencing factors among male and female university students in China. J Med Virol 2022; 94:2776-2786. [PMID: 34825712 PMCID: PMC9299831 DOI: 10.1002/jmv.27478] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Revised: 11/20/2021] [Accepted: 11/24/2021] [Indexed: 02/06/2023]
Abstract
This study compared the willingness to receive human papillomavirus (HPV) vaccination and the influencing factors between male and female university students who had never been vaccinated against HPV in China. University students were recruited from seven universities in China. A self-administered questionnaire was used to collect information about demographic characteristics, willingness to HPV vaccination, and possible influencing factors including demographics, knowledge, and attitude toward HPV vaccination. The χ2 test was used to test the difference between males and females' knowledge and attitudes to HPV vaccination. Multivariate logistic regression was employed to detect the factors associated with willingness to HPV vaccination. A total of 7335 university students participated in the survey (3570 males and 3765 females). Over 70% of the participants had previously received sex education and knowledge. The average age of sexual debut was 17.5 years old. More male students reported acceptance of premarital sex than female students did (χ2 = 708.458, p < 0.001). Female students had better knowledge and attitudes to HPV in general, while male students perceived a higher chance of being infected by HPV compared with female students (χ2 = 6.047, p = 0.014). The level of knowledge (male: adjusted odds ratio [AOR] = 1.935, 95% confidence interval [CI]:1.516-2.470; female: AOR = 1.227, 95% CI: 1.055-1.428) and receiving sex education (male: AOR = 1.414, 95% CI: 1.109-1.804; female: AOR = 1.289, 95% CI: 1.064-1.562) were indicators of the HPV vaccination willingness for both genders. For male students, those who had ever inoculated optional self-paid vaccines were more likely to receive the HPV vaccine than those who had not (AOR = 1.567, 95% CI: 1.242-1.977). Female students were more willing to be vaccinated against HPV, if they had higher living expenses (AOR = 1.395 and 3.717, 95% CI: 1.071-1.426 and 1.776-7.752), relatives or friends had certain cancer (AOR = 1.290, 95% CI: 1.095-1.518), ever had sexual experiences (AOR = 2.628, 95% CI: 1.788-3.863), and had ever consulted on HPV vaccination issues (AOR = 1.612, 95% CI: 1.367-1.901). In China, more active education should be provided to improve university students' knowledge and attitudes on HPV and HPV vaccination. Including HPV vaccine uptake for both males and females at recommended ages in National Immunization Program would be the most cost-effective way to prevent HPV infection.

Abstract
Objective To investigate the effect of a web-based educational intervention on changing female college students’ willingness and uptake of human papillomavirus (HPV) vaccines, and factors associated with HPV vaccination acceptance in Western and Northern China. Methods A web-based cluster randomized controlled trial was conducted in Western and Northern China from February to May 2020. A total of 967 female freshmen were recruited from two universities through convenience sampling, stratified sampling (liberal arts or sciences), and cluster sampling. Eligible students were randomized into intervention and control group with a 1:1 allocation ratio. The intervention group received seven days of web-based health education regarding HPV and HPV vaccines, whereas the control group received non-HPV-related materials. All students were asked to complete a post-intervention questionnaire to measure their awareness, uptake, and willingness to receive HPV vaccination at 7-day and one-month intervals. The chi-square test and Student’s t-test were employed to examine the differences between the intervention and control groups for categorical and continuous data. Logistic regressions were used to analyze factors associated with vaccination intentions. Results Nine hundred forty-six female freshmen aged 18.99 ± 0.63 years were enrolled in the study, with 532 in the intervention group and 414 in the control group. Prior to the intervention, 63.8%, 66.3%, and 60.8% of students had heard of HPV, HPV-related diseases, and HPV vaccines, respectively. Only 2.2% of students reported being vaccinated, but 33.0% were willing to be vaccinated against HPV. After seven days of education, students in the intervention group exhibited higher awareness (p < 0.001) and knowledge scores (5.13 ± 1.23 vs. 3.10 ± 1.99, p < 0.001) than those in the control group. Similarly, in the intervention groups, willingness to be vaccinated against HPV was significantly higher than in the control groups (p < 0.001). The high cost (57.7%) and concerns about adverse events (56.0%) were the main reasons female college students did not accept HPV vaccines. School location in urban areas, parents’ higher education backgrounds, history of HPV vaccination counseling, history of sexual behavior, and having heard of HPV vaccines were associated with a higher willingness to be vaccinated. Conclusion Female college students’ HPV vaccination uptake is insufficient, and they have minimal detailed knowledge about HPV and its vaccines. Web-based health education on HPV vaccines is an easy, feasible, and effective way to improve the awareness and acceptance of HPV vaccination among female college students, but it has limited effect on HPV vaccination uptake.

Abstract
BackgroundGender differences in mortality are embedded within mortality transitions. Rural residents generally lag behind their urban counterparts in the transitions. The study objective is to identify major causes of death that drive gender differences in mortality in urban and rural China.MethodsWe use age-, gender-, urban-rural- and cause-specific mortality data (2013–2018) derived from the national mortality surveillance system that covered about 24% of the Chinese population. We apply Arriaga's method to decompose age- and cause-specific contributions to the gender gap in life expectancy at birth. Analyses are stratified by urban-rural residence.ResultsWomen had a higher life expectancy at birth than men in both urban and rural areas. Cancers, cardiovascular disease, external causes, and respiratory disease accounted for more than 90% of the gender gap in both areas during 2013–2018. In urban areas, the gender gap decreased from 5.17 years in 2013–2015 to 4.98 years in 2016–2018. In rural areas, the gender gap stayed rather constant (2013–2015: 5.68 years; 2016–2018: 5.65 years). Traffic accidents, among external causes, contributed the most to decreasing the gender gap (urban: −0.07 years; rural: −0.10 years), especially in the 0–44 age group. However, the decrease in the gender gap was counteracted by an increase in the gender gap attributable to ischemic heart disease (urban: +0.05 years; rural: +0.08 years) and lung cancer (urban: +0.02 years; rural: +0.05 years) in older age groups. The gender gap attributable either to cerebrovascular disease or to chronic lower respiratory disease decreased in urban areas but increased in rural areas.ConclusionsThe urban-rural variations in the cause-specific contributions to the gender gap in China suggest the necessity of implementing urban-rural-specific interventions to improve population health and health equity.

Abstract
Objective Despite the fact that the human papillomavirus vaccine (HPVV) has been approved in mainland China since 2016, there is a lack of inoculation among Chinese college women. This multi-center, online interventional RCT based on the information-motivation-behavioral skills (IMB) model intended to investigate if the intervention may improve human papillomavirus vaccine acceptance and awareness among target women. Methods Participants were selected from comprehensive universities and allocated to 1 of 2 groups: intervention or control. After the baseline survey, participants in the intervention group were given 10-minute online IMB model-based education every day for 7 days. Self-administered questionnaire surveys on Human papillomavirus knowledge, HPVV acceptability, and IMB construct toward HPV vaccination were performed at pre- and post-intervention. Results The baseline survey was completed by 3739 female university students from the intervention (n = 1936) and control groups (n = 1803) between February and April 2020. The average score of students on 11 HPV-related questions was 5.225 ± 2.739, and only 32.07% (1199/3739) of them showed a willingness to be vaccinated against HPV. After the intervention, the intervention group had a higher willingness to vaccinate themselves and encourage their friends to get the HPVV compared to the control group (40.39% vs 31.56%, 82.67 vs 73.18%, P < .001), and the difference in knowledge scores between the 2 groups was significant (7.917 ± 1.840 vs 5.590 ± 2.859, P < .001). In addition, 8 students in the intervention group self-reported receiving HPVV during the research period. Conclusions This IMB model-based intervention showed positive effects on the participants’ knowledge, motivation, and perceived objective skills toward HPV vaccination and has the potential to improve the vaccination among Chinese college women.

Abstract
BACKGROUND This study aimed to assess the awareness and attitudes toward human papillomavirus (HPV) vaccination among female college freshmen and explore their willingness and associated factors to receive the HPV vaccine based on the information-motivation-behavior skills (IMB) model. METHODS From February 21 to April 30, 2020, a cross-sectional survey was conducted among female freshmen in seven colleges in mainland China. Socio-demographic characteristics, health-related awareness, knowledge of HPV, motivation, and behavioral skills toward HPV vaccination were assessed using questionnaires. Univariate and multivariate logistic regression analyses were performed to identify the influencing factors of willingness to receive the HPV vaccine in the next 6 months. RESULTS Among the 3867 students invited to participate in this study, 102 (2.64%) reported having taken the HPV vaccine. Among the unvaccinated participants, 59.89% had previously heard of HPV, and 32.08% were willing to take the HPV vaccine in the next 6 months. Willingness to get the HPV vaccine was associated with sexual experience(s) (AOR = 1.96, 95% CI: 1.25-3.08), family or friends with cancer (AOR = 1.24, 95% CI: 1.04-1.48), having heard of HPV (AOR = 1.23, 95% CI: 1.03-1.47), and having actively searched for or having consulted on issues concerning HPV vaccine (AOR = 1.22, 95% CI: 1.02-1.45). In the dimensions of the IMB model, "perceived susceptibility" (AOR = 1.20, 95% CI: 1.09-1.31), "perceived severity" (AOR = 1.24, 95% CI: 1.11-1.39), "subjective norms" (AOR = 2.09, 95% CI: 1.75-2.49), and "self-efficacy" (AOR: 2.95, 95% CI: 2.44-3.58) were positively associated with HPV vaccination acceptance, while "perceived barriers" (AOR = .60, 95% CI: .52-.69) negatively affected intention to get HPV vaccination. CONCLUSION HPV vaccination rates and willingness to receive the HPV vaccine in the next 6 months were found to be poor among female college freshmen in mainland China. Having a positive attitude toward HPV vaccination, creating vaccine-friendly social norms, and removing related barriers are important measures to promote HPV immunization.

Abstract
Background The increasing aging population has been posing a significant challenge to disease burden in developing countries. In particular, the contribution of population aging to and long term changes of disease burden of malignant neoplasm of female genital organs (MNFGO) have not been quantitatively demonstrated. Methods Data were collected from the Shanghai Vital Statistics System of Pudong New Area (PNA). Crude mortality rate (CMR), age-standardized mortality rate by Segi’s world standard population (ASMRW), and years of life lost (YLL) of MNFGO as the underlying cause of death in age and pathology types from 1995 to 2018 were calculated. The joinpoint regression was used to estimate the trends of those rates by identifying the annual percent changes (APCs), and the decomposition method was used to calculate the increased rates and the contribution resulting from demographic and non-demographic factors. Results From 1995 to 2018, a total of 2869 MNFGO-specific deaths were reported in PNA, accounting for 0.64% of the total deaths. The CMR and ASMRW of MNFGO were 9.23/105 person-years and 4.80/105 person-years, respectively. Ovary cancer was the most common cause of MNFGO death, accounting for 43.9% (1260/2869) of all MNFGO death. Other common causes of MNFGO death included cervix uteri cancer, uterus unspecified cancer, and corpus uteri cancer. With the increase of age, the mortality rate of MNFGO in residents had shown an upward trend ([APC (95%CI) = 3.46 (2.74, 4.18), P < 0.001)] for each five-year age group from 0 to 4 to 85+ years. From 1995 to 2018, YLL of MNFGO in Shanghai PNA was 42,152.82 years, and the rate of YLL was 135.56 /105. The top three MNFGO types in YLLs were ovary cancer, cervix uteri cancer and uterus unspecified cancer. Demographic factors contributed significantly to the upward trends of CMR, ASMRW, and YLL rates of MNFGO. Conclusion With aggravated population aging in Shanghai, MNFGO is and will continue to be a serious threat to women’s health. More precise and effective prevention strategies are needed to target high risk population, to achieve efficient health resource allocation and to improve women’s health in particular.

Abstract
BACKGROUND Healthcare workers (HCWs) play a key role in the recommendation of HPV vaccination. Our study aimed to understand to what extent a structured health intervention could change the knowledge and attitudes toward HPV and its vaccines among HCWs in Western China. METHODS This was a multi-center, questionnaire-based interventional study conducted across 12 cities of seven provinces in Western China, from November 2018 to July 2019. Participants were recruited from local health systems by e-invitation. Questionnaires were administered to participants before and after the intervention. RESULTS A total of 1448 HCWs attended the educational lectures and 1354 participants completed both pre- and post-study questionnaires. In general, HCWs had satisfactory baseline knowledge regarding HPV and its vaccines compared with other populations, and a significantly higher knowledge level was observed after the intervention. However, some more specific knowledge on the vaccination procedures, other HPV-related diseases and whether HPV testing was required before vaccination was relatively poor. Following the educational intervention, the correct responses to the above questions increased (P < .001). However, it was still lower compared with answers to other questions. Change was also detected regarding HCWs' willingness to recommend HPV vaccines to the appropriate population (P < .001). CONCLUSION Educational intervention on HPV and its vaccines is effective in improving HCWs' knowledge levels and willingness to recommend HPV vaccines. Future educational interventions should focus more on knowledge regarding HPV-related diseases and HPV vaccination. Education campaigns targeting rural HCWs are urgently needed in the near future.

Abstract
BACKGROUND Human papillomavirus (HPV) is associated with a substantial percentage of cervical cancer, and a significant percentage of anal, penile, vaginal, vulvar, oral cavity, oropharyngeal, and laryngeal cancers. Understanding the burden and trends of HPV-attributable cancers is crucial to HPV prevention strategies. In the current study, the authors estimated the latest burden and trends of HPV-attributable cancers in China. METHODS Data from the following sources were used. The number of new cancer cases and cancer deaths in China were estimated based on the China Cancer Registry Annual Report. The population-attributable fraction was estimated using pooled high-risk HPV prevalence and biomarker-positive rates, which were calculated using random effects meta-analyses. Cancer burden estimates were stratified by anatomic site, sex, and age. RESULTS In 2015, a total of 110,650 new cancer cases and 36,714 cancer deaths attributable to HPV infection were estimated to have occurred in China, of which cervical cancer accounted for 85.6% and 78.1%, respectively. The age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of HPV-attributable cancers were 5.63 and 1.81 per 100,000 person-years, respectively. The ASIR and ASMR both varied by anatomic site, with the highest rates noted for cervical cancer at 4.83 and 1.42 per 100,000 person-years, respectively. Between 2005 and 2015, the ASIR and ASMR demonstrated significant upward trends for all HPV-attributable cancers combined. CONCLUSIONS Between 2005 and 2015, cervical cancer accounted for the vast majority of HPV-attributable cancers and its incidence and mortality increased rapidly in China. The comprehensive prevention of cervical cancer remains the most important target in the prevention of HPV-attributable cancers.

Abstract
Little is known regarding Chinese mothers' intention to vaccinate their daughters against human papillomavirus (HPV) since the HPV vaccine was approved for use in China in 2016. The aim was to explore maternal HPV vaccination acceptance, preference for 2-, 4- or 9-valent HPV vaccine and acceptance of domestically manufactured HPV vaccines. Study participants were mothers of primary school children in Southeastern region of Fujian. An online cross-sectional survey was undertaken between June and August 2019. Among the total of 3,586 completed responses (response rate 28.5%), the intention to vaccinate daughter against HPV was high (83.3%). Higher maternal education and perceived benefit and barriers were associated with greater intention to vaccinate. Among mothers who did not intend to vaccinate their daughters, the three most common reasons were daughter being too young to receive HPV vaccination (40.6%), fear of side effects (31.9%) and vaccine price is too high (16.0%). The largest proportion (41.4%) preferred their daughter to be vaccinated with the 9-valent HPV vaccine (9vHPV). Greater preference for 9vHPVwas strongly associated with higher maternal education level and annual household income. The majority of mothers expressed a preference for imported HPV vaccine (56.3%). Our result indicates that lower intentions to vaccinate daughters against HPV among less educated and lower-income mothers may lead to significant social inequalities in HPV vaccine uptake in the country.

Abstract
BACKGROUND Little research has been conducted on the intention to obtain HPV vaccine now that the vaccine is approved for use in China. Acceptance of the three HPV vaccines, which differ in valency and price, has never been investigated. METHODS An online cross-sectional survey assessing female undergraduate students' intention to obtain the HPV vaccine and their acceptability of 2-, 4- and 9-valent HPV vaccines (2vHPV, 4vHPV, and 9vHPV, respectively). RESULTS Of a total of 997 complete responses, 55.2% reported intent to obtain the HPV vaccine. Some of the significant factors exerting influence on intent to obtain HPV vaccination were high knowledge score (OR = 1.469, 95% CI:1.087-1.987), perceived high risk of HPV infection (OR = 1.466, 95%CI:1.017-2.114), perception of no serious side effects (OR = 1.562, 95%CI:1.150-2.121), and mass media exposure to HPV vaccination information (OR = 2.196, 95%CI: 1.625-2.966). Socioeconomic status indicators did not significantly influence intent to obtain the HPV vaccine. A higher proportion of respondents were willing to pay for 2vHPV (78.6%) and 4vHPV (68.0%) compared with 9vHPV (49.3%). Socioeconomic status indicators were the strongest correlates of acceptability for all the three vaccines. Exposure to mass media reporting about HPV vaccination is the factor which exerts the most influence on acceptance of 9vHPV after socioeconomic status indicators. CONCLUSIONS It is important to improve knowledge and health beliefs, and to establish a mass media marketing strategy to promote HPV vaccination in order to enhance HPV vaccine uptake. Undergraduate female students should be provided with detailed information about the different valency vaccine choices to help them make informed decisions about immunization.
