Trends of cervical tumours amongst women from perspectives of demographic, socioeconomic and geographic indicators: retrospective ecological study in Czechia. Front Public Health 2024; 12:1347800. [PMID: 38813429 PMCID: PMC11133622 DOI: 10.3389/fpubh.2024.1347800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Accepted: 04/30/2024] [Indexed: 05/31/2024] Open
Abstract
Introduction For many infectious diseases, women are at higher risk and have a more severe disease course than men for many reasons, including biological differences, social inequalities, and restrictive cultural norms. The study focuses on infections with human papillomaviruses (HPV) in the form of cervical cancer as a gender-specific disease. The main goal is to evaluate cervical tumour incidence trends in the Czech female population in the HPV vaccination period 2012-2020 in relation to selected demographic, socioeconomic, and geographic indicators. Methods This is a retrospective ecological study. Data from publicly available databases about the incidence and mortality of cervical tumours (C53 Malignant neoplasm of cervix uteri, D06 Carcinoma in situ of cervix uteri according to ICD 10) and HPV vaccination rate were analysed and compared with demographic, socioeconomic and territorial data. Associations were searched using correlation analysis. Results There was a decreasing trend in the incidence of cervical cancer in the observed period. Regarding cervical tumours (C53, D06) and malignant neoplasm of cervix uteri incidence (C53), the decrease was approximately 11 and 20%, respectively. Differences between regions were observed in incidences and vaccination rates. Based on correlation analysis, indicators connected with urban/rural aspects, such as a share of urban population and population density, were statistically significant. The indicators related to higher cervical cancer incidence are the high unemployment rate of women, the high number of divorces, the high number of abortions, the high share of the urban population, the high number of students, and the high number of women with only primary education. On the other hand, the indicators related to lower cervical cancer incidence are the high gross domestic product (GDP), the high average gross monthly wage per employee, the high employment rate of women, the higher average age of mothers at birth, and the high number of women with tertiary education. Conclusion Results underline the problem of economically disadvantaged regions and families. Increasing vaccination rates, promoting regular screening for cervical cancer, and supporting awareness in the population, especially in regions with higher incidence rates, should be priorities for public health efforts.

Abstract
Anal human papillomavirus (HPV) infection has a high prevalence in men who have sex with men (MSM), resulting in an increased risk for anal cancer. The present work aimed to identify factors associated with HPV in a prospective cohort of HPV-vaccinated MSM using a random forest (RF) approach. This observational study enrolled MSM patients admitted to an Italian (sexually transmitted infection) STI-AIDS Unit. For each patient, rectal swabs for 28 different HPV genotype detection were collected. Two RF algorithms were applied to evaluate predictors that were most associated with HPV. The cohort included 135 MSM, 49% of whom were HIV-positive with a median age of 39 years. In model 1 (baseline information), age, age sexual debut, HIV, number of lifetime sex partners, STIs, were most associated with the HPV. In model 2 (follow-up information), age, age sexual debut, HIV, STI class, and follow-up. The RF algorithm exhibited good performances with 61% and 83% accuracy for models 1 and 2, respectively. Traditional risk factors for anal HPV infection, such as drug use, receptive anal intercourse, and multiple sexual partner, were found to have low importance in predicting HPV status. The present results suggest the need to focus on HPV prevention campaigns.

Abstract
BACKGROUND Integrated vaccine delivery - the linkage of routine vaccination with provision of other essential health services - is a hallmark of robust primary care systems that has been linked to equitable improvements in population health outcomes. METHODS We gathered longitudinal data relating to routine immunization coverage and vaccination equity in 78 low- and middle-income countries that have ever received support from Gavi, the Vaccine Alliance, using multiple imputation to handle missing values. We then estimated several group-based trajectory models to describe the relationship between integrated vaccine delivery and vaccination equity in these countries. Finally, we used multinomial logistic regression to identify predictors of group membership. RESULTS We identified five distinct trajectories of geographic vaccination equity across both the imputed and non-imputed datasets, along with two and four trajectories of socioeconomic vaccination equity in the imputed and non-imputed datasets, respectively. Integration was associated with reductions in the slope index of inequality of measles vaccination in the countries analyzed. Integration was also associated with an increase in the percentage of districts reporting high measles vaccination coverage. CONCLUSIONS Integrated vaccine delivery is most strongly associated with improvements in vaccination equity in settings with high baseline levels of inequity. Continued scholarship is needed to further characterize the relationship between integration and health equity, as well as to improve measurement of vaccination coverage and integration.

Age, gender and socioeconomic disparities in human papillomavirus (HPV) awareness and knowledge among Japanese adults after a 7-year suspension of proactive recommendation for the HPV vaccine: A nationally representative cross-sectional survey. Vaccine 2023; 41:7147-7158. [PMID: 37866996 DOI: 10.1016/j.vaccine.2023.10.024] [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: 05/25/2023] [Revised: 09/21/2023] [Accepted: 10/11/2023] [Indexed: 10/24/2023]
Abstract
The Japanese government's 2013 suspension of its proactive recommendation for Human papillomavirus (HPV) vaccination resulted in low HPV vaccination coverage and was unique. However, data on awareness and knowledge of HPV vaccines in the general population was limited. Here, to investigate more recent awareness and knowledge of HPV vaccines by age, gender, and socioeconomic status, we used data from the INFORM Study 2020, a nationally representative cross-sectional survey of self-administered questionnaires with 1,998 Japanese individuals aged 20 to 59 years. We found that 47.5% of females and 21.0% of males had heard of HPV, and 33.6% of females and 16.8% of males had knowledge of HPV vaccine efficacy. After adjusting for potential confounders, females aged 50-54 years were more likely to be aware of HPV than females aged 20-24 (AOR, 2.02, 95%CI: 1.12-3.65). Females (AOR, 2.13, 95%CI: 1.48-3.07) and males (AOR, 1.64, 95%CI: 1.03-2.59) with higher education had more awareness than those with less education. Females with higher education had more knowledge about HPV vaccine efficacy than those with less education (AOR, 1.70; 95%CI: 1.16-2.50). We found a generally low level of awareness and knowledge about HPV vaccines in Japan, which might be attributable to the suspension of proactive recommendations. Additionally, we identified disparities in awareness and knowledge by age, gender, socioeconomic status, and health literacy. Enhancing HPV awareness and understanding of HPV vaccines and implementing targeted efforts for specific subpopulations within Japan after the resumption of proactive recommendation for HPV vaccines, are imperative.

Abstract
OBJECTIVE Isolation and school closure during the COVID-19 pandemic could decrease human papillomavirus (HPV) vaccination uptake and potentially increase future HPV-related morbidity among unvaccinated populations. The aim of our study was to investigate HPV vaccination rates in Israel during the pandemic. METHODS The HPV vaccination rates were compared before and during the COVID-19 pandemic years (2020-2021). Data regarding HPV vaccination between 2015 and 2021 were extracted from the Israeli Ministry of Health online reports. Vaccination rates were compared with other childhood vaccines, given at similar ages. Israeli HPV vaccination rates were further compared with England and Australia, which have an established vaccination infrastructure. RESULTS The average Israeli coverage of first-dose HPV vaccine was 60.2%, with significant variations from 2015 to 2021. During the pandemic years, first-dose vaccine coverage increased compared with the 3 previous years. The pandemic had also no apparent influence on other childhood vaccine uptake, even though adolescents in Israel missed many school days during this time. Average vaccine uptake in England and Australia was significantly higher than Israel ( p = .009); however, first-dose vaccination rates decreased considerably in England during 2020, to a nadir of 59%. The pandemic had little effect on HPV vaccination rates in Australia. CONCLUSIONS Despite many school days missed, the COVID-19 pandemic did not result in a decrease in HPV vaccine uptake in Israel. The pandemic could prove a good opportunity to further educate the public regarding the importance of whole-population vaccination programs. Implementing catch-up vaccination programs may bridge "vaccination gaps" that may be caused by future pandemics.

Abstract
BACKGROUND The human papillomavirus (HPV) vaccine reduces the burden of cervical and other cancers. In numerous countries, a slow uptakeof this vaccine persists, calling for a better understanding of the structural factors leading to vaccine acceptation. We aimed to assess the attitudes toward HPV vaccination among its intended public to explore its specific characteristics. METHODS A random cross-sectional telephone survey of the French general population provided data from a sample of 2426 respondents of the target public: the parents of young women and the young women aged 15-25 themselves. We applied cluster analysis to identify contrasting attitudinal profiles, and logistic regressions with a model averaging method to investigate and rank the factors associated with these profiles. RESULTS A third of the respondents had never heard of HPV. However, most of the respondents who had heard of it agreed that it is a severe (93.8%) and frequent (65.1%) infection. Overall, 72.3% of them considered the HPV vaccine to be effective, but 54% had concerns about its side effects. We identified four contrasting profiles based on their perceptions of this vaccine: informed supporters, objectors, uninformed supporters, and those who were uncertain. In multivariate analysis, these attitudinal clusters were the strongest predictors of HPV vaccine uptake, followed by attitudes toward vaccination in general. CONCLUSIONS Tailored information campaigns and programs should address the specific and contrasted concerns about HPV vaccination of both young women and of their parents.

Abstract
OBJECTIVE To assess the public health impact and cost effectiveness of gender-neutral vaccination (GNV) versus female-only vaccination (FOV) with human papillomavirus (HPV) vaccination in Japan. METHODS We modeled the public health impact and cost effectiveness of GNV versus FOV to prevent HPV-associated diseases in Japan over the next 100 years. We used one-way sensitivity analyses to examine the impact of varying key model input parameters and conducted scenario analyses to explore the effects of varying the vaccination coverage rate (VCR) of each cohort. RESULTS In the base-case analysis, GNV averted additional cancer cases (17,228 female/6,033 male) and deaths (1,892 female/1,849 male) compared to FOV. When all HPV-associated diseases were considered, GNV had an incremental cost-effectiveness ratio of ¥4,732,320 (US$35,987)/quality-adjusted life year gained compared to FOV. The model was most sensitive to the discount rate and the disutility associated with HPV-related diseases. GNV had greater relative public health benefits when the female VCR was lower and was cost effective at a female VCR of 30%. CONCLUSIONS Immediate implementation of GNV would reduce the disease burden and mortality associated with HPV in Japan, and would be cost effective compared to FOV if the female VCR remains low (30%).

Abstract
Human papilloma virus (HPV) is the most common sexually transmitted infection in the United States. Disease-associated strains of HPV can cause genital warts and six cancer types. HPV-associated cervical cancer disproportionately impacts medically underserved women including Black and Latina women with respect to incidence, prevalence, and mortality rates. Although safe and effective vaccines are available, HPV vaccination rates remain low among low-income individuals and women of color. The current study examined individual and structural motivators and barriers to HPV vaccination among medically underserved women utilizing a Planned Parenthood health center in Southeast Pennsylvania. Guided by narrative engagement theory (NET), qualitative interviews (N = 24) were used to elicit HPV vaccine decision stories from both vaccinated and unvaccinated women. Using a phronetic iterative data analysis approach, we identified three motivators to vaccinate against HPV: (1) receiving an explicit vaccine recommendation from a healthcare provider (a structural determinant), (2) feeling empowered to take control of one’s health (an individual determinant), and (3) knowing someone infected with HPV (an individual determinant). Among unvaccinated participants, barriers to HPV vaccination included: (1) not receiving an explicit vaccine recommendation from a healthcare provider (a structural determinant), (2) low perceived risk for acquiring HPV or that HPV is not severe (an individual determinant), and (3) lack of maternal support to vaccinate (a structural determinant). Healthcare providers are optimally positioned to fill the gap in prior missed vaccine opportunities and empower women by recommending HPV vaccination.

Abstract
While launching a campaign to eliminate cervical cancer, the World Health Organization called to halt human papillomavirus (HPV) gender-neutral vaccination (GNV) because of limited vaccine supply, raising ethical and legal questions about female-only vaccination versus GNV. We identified ethical and legal aspects of HPV GNV by searching MEDLINE for records up to February 19, 2021. We also provided an overview of HPV vaccines, the evolution of HPV vaccine recommendations in North America, and a timeline of male HPV vaccination introduction by searching PubMed, Google, and government websites. Four HPV vaccines are available: Cervarix®, Gardasil®, Gardasil®9, and Cecolin®. Vaccine recommendations in North America evolved from female only to eventually include males. Following the Food and Drug Administration's approval of the first HPV vaccine for males (2009), 35 countries began vaccinating males (2011-2020). Based on 56 eligible records out of 652, we identified the following constructs: lower male awareness of HPV and vaccination (n=13), limited economic resources (n=5), shared social responsibility (n=18), unprotected groups from female-only HPV vaccination (n=10), limited screening for HPV-associated noncervical cancers (n=6), consideration of ethical principles (n=17), and HPV vaccine mandates (n=5). Ethical and legal aspects must be considered when recommending vaccination for females only or GNV.

Abstract
BACKGROUND There are currently no available standard drugs treating human papillomavirus (HPV) infection, especially for patients with low-grade cervical lesion. Several therapies are explored but the results are inconclusive. The objective of this study was to evaluate the efficacy of reported non-invasive treatments in patients with HPV infection and cervical lesions by meta-analysis. METHODS A comprehensive search of prospective and randomized studies published from April 2000 to April 2020 was conducted in electronic databases. The statistical analyses of the pooled risk ratios (RRs) and the corresponding 95% confidence intervals (95% CIs) were performed using the Revman 5.2 software. RESULTS Twelve articles including 12 randomized controlled studies and 1 prospective controlled randomized pilot study were enrolled. Therapeutic medications included biological and herbal regimen, interferon regimen and probiotics. The meta-analysis showed the experimental treatments had a statistically significant improvement in HPV clearance rate compared with the controls (RR = 0.71, 95% CI [0.63, 0.80], P < .00001); subgroup analyses stratified by regimen categories were consistent with results in the overall group. Treatment using biological and herbal regimen, interferon regimen or probiotics also resulted in a beneficial outcome in regression rate of cervical lesions compared with the controls (RR = 0.55, 95% CI [0.39, 0.79], P = .001). The trend was more favorable in the probiotics than that in the biological and herbal regimen (RR 0.48 vs 0.72). CONCLUSION Treatment of biological and herbal regimen, interferon regimen and probiotics benefit patients who have HPV infection and cervical lesions. Both the clearance of HPV and regression of cervical lesions are significant. More studies with less heterogeneity are needed to draw a concrete conclusion.

The Adoption of Preventive Behaviors during the COVID-19 Pandemic in China and Israel. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17197170. [PMID: 33007985 PMCID: PMC7579051 DOI: 10.3390/ijerph17197170] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Revised: 09/25/2020] [Accepted: 09/28/2020] [Indexed: 11/23/2022]
Abstract
The COVID-19 pandemic represents a massive global health crisis. The rapid transmission rate of the virus, as well as the lack of effective medications and vaccines, has posed serious challenges to controlling the spread of the disease. Dealing with this public health crisis has required major changes in people’s behavior, including the adoption of social distancing measures such as avoiding meeting with family members and friends, crowded places, and public transportation. The purpose of this study is to investigate the factors associated with the adoption of these behaviors in China and Israel. We relied on the 3Cs model that has been used to predict the adoption of a specific preventive behavior (vaccinations) with the goal of testing its applicability to other preventive behaviors such as in response to the COVID-19 pandemic. The model indicates that confidence in social institutions, complacency (fear of and assessments about the risk of becoming ill) and constraints (levels of self-efficacy and confidence in being able to engage in the behaviors) are predictors of adopting preventive behaviors. Data were collected in China and Israel through an online survey of the population (n = 1406). We used latent variables and structural equation modeling to test the hypotheses derived from the 3Cs model. The findings indicate that there are some differences in the types of preventive behaviors adopted in the two countries. In Israel, higher levels of confidence predicted the adoption of avoidant behaviors and more constraints predicted engaging in fewer avoidant behaviors. In China, more constraints also contributed to the adoption of fewer avoidant behaviors, but people’s level of confidence fully mediated this result. The multi-group analysis indicated that the conceptualized model fits the Chinese and Israeli data reasonably well. The findings suggest that the 3Cs model can be generalized from getting vaccinated to adopting avoidant behaviors and that the model can be used across cultures and countries.
