Acceptance of the Human Papillomavirus Vaccine among General Men and Men with a Same-Sex Orientation and Its Influencing Factors: A Systematic Review and Meta-Analysis. Vaccines (Basel) 2023; 12:16. [PMID: 38250829 PMCID: PMC10819436 DOI: 10.3390/vaccines12010016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Revised: 12/14/2023] [Accepted: 12/17/2023] [Indexed: 01/23/2024] Open
Abstract
The human papillomavirus (HPV) vaccine reduces the prevalence of genital warts and the cancers they are associated with in males. However, the vaccination of males has always been neglected. Here, we performed a meta-analysis to comprehend the acceptability of the HPV vaccine in men and the factors impacting vaccination intentions. We searched PubMed, Web of Science, Embase, Ovid, CNKI, and Wan Fang up to 5 July 2023 for studies that reported HPV vaccine acceptance among men. A random effects model was used to obtain the pooled acceptance rate, and subgroup analysis was performed. Then, the influencing factors of HPV vaccination in males were analyzed. A total of 57 studies with 32,962 samples were included in the analysis. The overall acceptance rate of the HPV vaccine in general men was 47.04% (95% confidence interval [95%CI]: 39.23-54.93%), and 62.23% (95% CI: 52.93-71.10%) among those whose sexual orientation contained men. HPV vaccine acceptance rates differed significantly between the two populations (p = 0.01). The population with a medical background (46.23%, 95% CI: 40.28-52.24%) was more willing to be vaccinated. In comparison to the employed population (66.93%, 95% CI: 48.79-82.81%) and the unemployed (68.44%, 95% CI: 52.82-82.23%), vaccination acceptance rates were lower among students (47.35%, 95% CI: 37.00-57.81%) (p = 0.04). The most significant barriers to vaccination were perceived low risk of infection for themselves (45.91%, 95% CI: 31.73-60.43%), followed by vaccine cost (43.46%, 95% CI: 31.20-56.13%). Moreover, the recommendations from medical professionals (60.90%, 95%CI: 44.23-76.37%) and sexual partners (60.09%, 95%CI: 27.11-88.67%) were significant factors in promoting vaccination. Overall, acceptance of the HPV vaccine among general men was at a lower level, despite being slightly higher among men with a same-sex orientation. Popularizing knowledge about diseases and vaccines, encouraging medical professionals to recommend vaccines to men, or reducing the cost of vaccines may promote HPV vaccination.

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. Vaccines (Basel) 2023; 11:1614. [PMID: 37897016 PMCID: PMC10610837 DOI: 10.3390/vaccines11101614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 09/24/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
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.

Vaccines (Basel) 2023; 11:1429. [PMID: 37766106 PMCID: PMC10538197 DOI: 10.3390/vaccines11091429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 08/20/2023] [Accepted: 08/25/2023] [Indexed: 09/29/2023] Open
Abstract
Background: men who have sex with men (MSM) are a high-risk group for human papillomavirus (HPV) infection, and the HPV vaccine is effective in preventing it. However, according to risk compensation theory, people may increase sexual risk behaviors after receiving HPV vaccination. Based on the Health Action Process Approach (HAPA), this study investigated the influencing factors to predict intention to reduce condom use (risk compensation intention) among MSM after taking HPV vaccination in southwest China. Methods: we conducted a cross-sectional study among 948 MSM in southwest China using a non-probability sampling method and an electronic questionnaire including sociodemographic characteristics, sexual risk behavior characteristics, HPV-related prevention behavior, and the HAPA scale. Confirmatory factor analysis was performed using a structural equation model. Results: among 948 MSM, the incidence rate of reducing the frequency of condom use was 14.1%. The structural equation model showed that self-efficacy (β = -0.378, p = 0.020) and positive outcome expectancy (β = 0.366, p < 0.05) had greater effects on behavioral intention, followed by negative outcome expectancy (β = -0.296, p < 0.05) and risk perception (β = -0.232, p < 0.05). Conclusions: risk compensation may not be a major barrier to receiving HPV vaccination among MSM. Nevertheless, the recognition of possible risk compensation is necessary to implement appropriate interventions to reduce the occurrence of risk compensation.

Abstract
The dissemination of the fact that the human papillomavirus (HPV) vaccine can protect females as well as males is greatly beneficial for the control of condyloma acuminata (CA). We aimed to investigate the acceptance of the HPV vaccine for CA among men who have sex with men (MSM) in China. A cross-sectional online survey in the adult MSM population from 31 regions in China was carried out via WeChat in May 2017. Information on demographic characteristics, sexual behaviors, history of HIV and HPV infection, awareness of CA and HPV/CA vaccines, acceptance of CA vaccination, and behavioral intentions for vaccination were collected through a self-administered questionnaire. In total, 902 questionnaires were analyzed; the prevalence of CA was 13.3% (120/902), the HIV positivity rate was 15.1% (136/902), and the coinfection rate of HIV and CA was 3.9% (35/902). In the MSM population, the knowledge of CA and HPV/CA vaccines was poor, but the acceptance rate of the CA vaccine was high (85.1%, 768/902). Data indicated that MSM who had a history of anal intercourse (OR = 1.9), had heard of CA (OR = 2.9), knew the treatments for CA (OR = 2.0), had heard of HPV vaccines/cervical cancer vaccines (OR = 1.9), and received education about CA (OR = 1.9) were associated with the intention to use CA vaccines. With current moderate levels of CA and HPV/CA vaccine awareness, more emphasis should be placed on improving education and other behavioral interventions for high-risk populations such as MSM in China.

Abstract
(1) Background: Men who have sex with men (MSM) are at high risk of human papillomavirus (HPV) infection, and HPV vaccination is the best strategy to prevent HPV infection. Accepting HPV vaccination is an essential factor affecting vaccine promotion among MSM. We aimed to explore the factors related to HPV vaccination intention among MSM and analyze the potential relationship between these factors. (2) Methods: We adopted a nonprobability sampling method to recruit MSM volunteers. Information collection included general demographics, personal behavioral characteristics, knowledge of HPV/vaccine attitudes, and risk threat perception. Bayesian networks (BNs) were used to analyze the data statistically. (3) Results: The BNs showed that perceived HPV risk and attitudes toward vaccine promotion were directly correlated factors, whereas knowledge of HPV/vaccines, a history of HIV testing, and the number of male sexual partners in the past 6 months were indirectly correlated factors. (4) Conclusions: The results of this study illustrate that MSM have a relatively high propensity to receive HPV vaccines. The proposal that strengthening the propagation of HPV and its relevant vaccines, encouraging MSM to undergo regular corresponding tests, and improving their risk perception of HPV infection can be raised to promote HPV vaccination among MSM.

Vaccines (Basel) 2022; 10:vaccines10071054. [PMID: 35891217 PMCID: PMC9319647 DOI: 10.3390/vaccines10071054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 06/25/2022] [Accepted: 06/28/2022] [Indexed: 02/01/2023] Open
Abstract
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.
