Factors Associated with College Students' Human Papillomavirus (HPV) Vaccination and Preferred Strategies for Catch-Up Vaccine Promotion: A Mixed-Methods Study

Perspectives of HPV vaccine decision-making among young adults: A qualitative systematic review and evidence synthesis

BACKGROUND

Despite the demonstrated safety and effectiveness of HPV vaccines in preventing HPV-related cancers, global vaccine coverage remains low. The suboptimal adolescent HPV vaccine coverage rate leaves many young adults at increased risk for developing vaccine preventable HPV-related cancers. This qualitative evidence synthesis (QES) aims to examine the HPV vaccination perspectives of young adults globally and identify the barriers and facilitators to HPV vaccine uptake and decision-making processes.

METHODS

A comprehensive search was conducted on October 2023 across seven databases to identify studies that reported on HPV vaccination among young adults aged 18-26 years and used qualitive study methods or analysis techniques.

RESULTS

Forty-two studies were purposively sampled for inclusion, presenting 29 findings across 10 thematic categories. Vaccine eligible young adults believed that they had aged out of eligibility for HPV vaccination. There was also a perspective that condom use, and regular screenings were alternatives to vaccination in preventing HPV infections. Challenges included scheduling appointments, requirements for multiple shots, and vaccine cost. There was also concern for the gendered nature of vaccine promotion. Lastly, despite being at the age to make autonomous decisions, parents were still influential and active in the vaccine decision-making process for their children.

CONCLUSION

The novelty of this study, as one of the principal QES on catch-up HPV vaccination, presents findings that underscore the complexity of factors across multiple ecological levels which may aid or impede vaccination uptake among young adults and provide important considerations for interventions, programs, and policies aimed at addressing HPV vaccination disparities among young adults.

"If I Start [Primary Prevention] Now, I Can Prevent [Cancer]": College Students Endorse Cancer Prevention Education

Early onset colorectal cancer has been linked to lifestyle-related risk factors. Emerging adulthood (ages 18-25) has the greatest changes to lifestyle health behaviors with implications for health outcomes. College students have moderate consideration of future cancer risk (CFC-CA) when navigating current health behavior choices. This study explored cancer prevention knowledge, attitudes and behavioral intentions in a subset of students with low, medium and high CFC-CA. Qualitative interviews were used to explore cancer prevention among a sample of college students. We identified a stratified sample (N = 43) of high CFC-CA (n = 16), medium CFC-CA (n = 14), and low CFC-CA (n = 13) students who agreed to complete a 60-min interview on Zoom. Interviews were transcribed verbatim, and transcripts were coded using an iterative, line-by-line approach. Group comparisons were completed after coding was complete. Students exhibited greatest awareness of highly publicized cancers including the lung, breast, and skin. Fifty-four percent of those with low CFC-CA and 87% with high CFC-CA believe that their current health behavioral intentions are protective against cancer. Most students want more cancer education regardless of CFC-CA level to know how they can reduce their cancer risk. Differences in preferred information sources (indirect vs direct) were identified for low versus higher CFC-CA, respectively. Students' preferences for cancer education were related to their CFC-CA scores. This could be used to tailor information content and delivery modality. Delivering cancer prevention education through means that facilitate internal reflection may be more effective for improving risk reduction behaviors.

Knowledge, attitude, and reasons for non-uptake of human papilloma virus vaccination among nursing students

BACKGROUND

Cervical cancer is a significant health issue, especially in low- and middle-income countries like India, where it ranks fourth among women. The Human papillomavirus (HPV) vaccination, a vital preventive measure, has suboptimal uptake among nursing students. We aimed to assess the level of knowledge, attitudes, willingness, and reasons for non-uptake of HPV vaccination among nursing students.

METHODS

A descriptive cross-sectional study was conducted from April to June 2023, using a total enumeration method. Data were collected from 313 nursing students using a validated questionnaire covering sociodemographic information, knowledge, attitudes, and reasons for non-uptake of HPV vaccination. Statistical analysis was performed using SPSS version 26.0. Descriptive statistics summarized the data, while binary and multivariable logistic regression analyses identified factors associated with knowledge, attitude, and willingness for HPV vaccination.

RESULTS

The mean age of the students was 20.98 ± 2.38 years, with the majority being females (81.2%) and unmarried (93.0%). About half of the participants demonstrated moderate knowledge (52.4%) and negative attitudes (50.1%) towards HPV vaccination, with none having received the vaccine. Female students had 4.24 times the odds of having good knowledge (AOR = 4.24, 95% CI = 1.66-10.80), while those pursuing a bachelor's degree exhibited 2.70 times the odds of good knowledge (AOR = 2.70, 95% CI = 1.40-5.21). In contrast, first-year students had 0.30 times the odds of having good knowledge (AOR = 0.30, 95% CI = 0.11-0.79) but displayed 4.69 times the odds of having a positive attitude (AOR = 4.69, 95% CI = 1.92-11.41). Additionally, Hindu students had 2.44 times the odds of being willing to receive the vaccine (AOR = 2.44, 95% CI = 1.15-5.20). Most participants expressed willingness to receive the vaccine (62.0%), citing reasons such as not being sexually active (35.8%) and needing more information (18.2%) for non-uptake of the vaccine.

CONCLUSIONS

The study highlights gaps in knowledge and negative attitudes towards HPV vaccination among nursing students. Targeted educational interventions and policy initiatives are essential to improve awareness, promote positive attitudes, and increase HPV vaccination uptake among nursing students.

Effects of different educational interventions on cervical cancer knowledge and human papillomavirus vaccination uptake among young women in Japan: Preliminary results of a cluster randomized controlled trial

The incidence and mortality rates of cervical cancer are increasing among young Japanese women. In November 2021, the Japanese Ministry of Health, Labour, and Welfare reinstated the active recommendation of the human papillomavirus (HPV) vaccine, after it had been suspended in June 2013 due to reports of adverse reactions. However, vaccine hesitancy is prevalent in the younger generation in Japan. To identify obstacles to vaccine uptake, we conducted a randomized study using different methods to provide educational content to improve health literacy regarding cervical cancer and HPV vaccination among Japanese female students. We surveyed 188 Japanese female students, divided into three groups according to the intervention: no intervention, print-based intervention, and social networking service-based intervention. Twenty questionnaires and the Communicative and Critical Health Literacy scales were used as health literacy scales. Participants' knowledge and health literacy improved regardless of the method of education. In fact, participants acquired proper knowledge when given the opportunity to learn about the importance of the disease and its prevention. Therefore, medical professionals in Japan must provide accurate scientific knowledge regarding routine HPV vaccination and the risk of cervical cancer in young women to improve their health literacy and subsequently increase HPV vaccination rates in Japan, which may lead to cervical cancer elimination.

Examining HPV vaccination behavior among young adults: Insights from applying the Health Belief Model

BACKGROUND

Despite evidence-based recommendations for HPV vaccination, uptake among young adults is suboptimal. Limited research has explored factors that may influence HPV vaccination among young adults, as well as associated promotion and informational preferences in this group. This study aimed to examine factors associated with HPV vaccination among young adults and preferences for HPV vaccine information and promotion.

METHODOLOGY

This study utilized a cross-sectional design to examine factors related to HPV vaccination among young adults on a university campus in Tennessee. Data were collected via an online survey administered to students, aged 18-26 years, from March-May 2023. Study measures included sociodemographic characteristics, health/healthcare-related factors, and perception-related measures. Data analysis included descriptive statistics and multivariable logistic regression analysis.

RESULTS

Out of 402 participants that completed the survey, 209 reported being vaccinated against HPV. In the adjusted model, variables associated with HPV vaccination were perceived risk (adjusted OR [aOR] = 1.12; 95% confidence interval [CI]:1.05, 1.20), perceived barriers (aOR = 0.73; 95% CI: 0.66, 0.81), higher HPV knowledge (aOR = 1.17; 95% CI: 1.03, 1.33), and receipt of healthcare provider recommendations (aOR = 12.90; 95% CI: 7.08, 23.51).

CONCLUSIONS

Study findings suggest that those who are vaccinated were more likely to report receiving healthcare provider recommendations, low perceived barriers, higher HPV knowledge and perceived risk. Future HPV vaccination promotion efforts for young adults may consider increasing HPV vaccine knowledge and awareness, addressing barriers, and strengthening provider recommendations.

A transversal cross-sectional study of factors related to HPV vaccination status and cancer screening participation among French women aged 25-40

BACKGROUND

In 2020, uterine cervical cancer (UCC) was the 12th most common cancer among women in France and the 4th worldwide. French health authorities wanted to increase Human Papilloma Virus (HPV) vaccination and screening rates. There were still many barriers to these measures among young women, their families, and health professionals and teachers. Between 2014 and 2019, international studies found inconsistent effects of HPV vaccination on UCC screening. In 2022, a survey was conducted among women aged 25 to 40 in the Nord-Pas-de-Calais region to assess participation 1) in HPV vaccination and its barriers, 2) in UCC screening as a function of HPV vaccination status.

METHODS

Data were collected using an anonymous online questionnaire distributed by QR code in 80 general practices randomly selected in the Nord-Pas-de-Calais region between January and June 2022. Results were analyzed bivariately using the Chi2 test, multivariately when numbers allowed, and in age subgroups (sensitivity analysis).

RESULTS

407 complete questionnaires (for 602 participating women) were analyzed. In our sample, 41% of women aged 25 to 40 in the Nord-Pas-de-Calais region were vaccinated against HPV viruses in 2022. The risk factors for non-vaccination, after multivariable adjustment, were: the periods of eligibility for vaccination in the early days of French vaccination (2007-2012: odds ratio OR = 0.04 [95% CI, 0.02-0.09]; 2012-2017: OR = 0.5 [0.3-0.8]), information received from non-medical sources (OR = 0.3 [0.2-0.6]), and absence of information about vaccination (OR = 0.12 [0.05-0.27]). In our sample, 90% of women were screened for UCC. In bivariate analysis, women at risk of not being screened were those who were youngest, had been vaccinated against HPV, were not heterosexual, lived alone, had gynecological follow-up by their general practitioner, and did not have regular gynecological follow-up. Sensitivity analysis showed that the only risk factor significantly correlated with non-screening regardless of age group was lack of regular gynecological follow-up.

CONCLUSIONS

Participation in HPV vaccination and UCC screening is improved by medical education and gynecological follow-up. This multicenter study, limited by the relative youth of vaccination in France, should be repeated after 2037 to assess the possible effect of vaccination on screening.

Human Papillomavirus Perceptions, Vaccine Uptake, and Sexual Risk Factors in Students Attending a Large Public Midwestern University

Background: It was to understand HPV vaccination patterns, uptake, perceptions, and sexual risk factors in students at a Midwest public university. Participants: Students were enrolled during the spring 2024 semester at the University of Iowa. Methods: A survey was developed and emailed to 28,095 students asking demographic, general and sexual health, and HPV-related questions. Results: The response rate was 4.9%, with 76% females and a median age of 22. The HPV vaccine uptake was 82%, with 88% recommending the vaccine. Parental preference was the main reason for being unvaccinated. The median age of sexual debut was 17 years, with a median of 2 sexual partners. Vaccination was associated with female, health science, sexually active, and COVID-19/influenza vaccinated students. Conclusions: HPV vaccine uptake at University of Iowa students is higher than the national and Iowa averages. Increased education regarding HPV vaccination is still needed, particularly in males, those not having sex, and those not receiving other vaccines.

Predictors of seasonal influenza and COVID-19 vaccination coverage among adults in Tennessee during the COVID-19 pandemic

Background

The COVID-19 pandemic has convoluted hesitancy toward vaccines, including the seasonal influenza (flu) vaccine. Because of COVID-19, the flu season has become more complicated; therefore, it is important to understand all the factors influencing the uptake of these vaccines to inform intervention targets. This article assesses factors related to the uptake of influenza and COVID-19 vaccines among adults in Tennessee.

Methods

A cross-sectional, secondary data analysis of 1,400 adults was conducted in Tennessee. The adult sample came from two data sources: Data source 1 completed a baseline survey from January to March 2022, and data source 2 was completed from May to August 2022. Data on vaccine attitudes, facilitators and barriers, and communication needs were collected via random digit dial by Scientific Telephone Samples (STS). Two multivariable logistic regression models were used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) to predict sociodemographic and overall vaccine-related factors associated with receipt or non-receipt (referent) of COVID-19 and influenza vaccines.

Results

Approximately 78% of the adult sample had received the COVID-19 vaccination. A significant positive association for COVID-19 vaccine uptake was seen among those who were older (aged 50-65) (aOR = 1.9; 95% CI: 1.2-3.2), Black (aOR = 2.0; 95% CI:1.3-2.8), and had a college education and higher (aOR = 2.3; 95% CI: 1.5-3.6). However, there was a significant negative association for persons reporting they were extremely religious (aOR = 0.5; 95% CI:0.3-0.9). Over 56% of the adult sample had received the influenza vaccination this season. Those who had a higher annual household income ($80,000+) (aOR = 1.9; 95% CI: 1.3-2.6) and had health insurance (aOR = 2.6; 95% CI: 1.4-4.8) had a significant positive association with influenza vaccine receipt. However, those who were employed part-time or were unemployed had a significant negative association for influenza vaccine receipt (aOR = 0.7; 95% CI: 0.5-0.9). Both COVID-19 and influenza vaccine receipt had strongly significant positive trends with increasing belief in effectiveness and trust (p < 0.0001) and strongly significant negative trends with higher levels of overall vaccine hesitancy (p < 0.0001).

Conclusion

Strategies to increase COVID-19 and influenza vaccination should be age-specific, focus on increasing geographical and financial access, and offer tailored messages to address concerns about these vaccines.
