Awareness of HPV and HPV vaccine among college students in China

Background

Cervical cancer is the fourth most common cancer among women, HPV vaccine can reduce the incidence of cervical cancer by approximately 70%. Sexual behavior is a direct risk factor for HPV infection, and sexually active college students, therefore, receive attention for HPV vaccination. This study aimed to investigate the awareness of HPV and its vaccine among college students in Zhengzhou, and to explore the factors influencing their awareness of HPV vaccine, to understand college students' willingness to receive the vaccine. The findings of this study will lay a foundation for cervical cancer prevention.

Methods

Using a multistage random sampling method, 650 college students from four universities in Zhengzhou were selected. A self-administered questionnaire on the awareness of HPV and its vaccine, and willingness to receive HPV vaccination was carried out. Logistic regression was used to analyze the factors influencing students' awareness of the HPV vaccine.

Results

58.0% of college students had heard of HPV, and 72.8% of college students had heard of HPV vaccine. Logistic regression showed that gender, major, grade, mean monthly consumption level, sexual history, and mother cervical cancer screening participation significantly influenced the awareness of HPV vaccine (p < 0.05). Only 27(4.2%) college students had received the HPV vaccine. 63.2% of college students expressed their willingness to get vaccinated.

Conclusion

The awareness of HPV and its vaccine among college students in Zhengzhou needs improvement. Although the vaccination rate is low, most college students are willing to be vaccinated. Diverse health education programs should be conducted for different groups to improve awareness of cervical cancer prevention and promote vaccination.

Providing parents with HPV vaccine information from a male perspective may render them more inclined to have their daughters vaccinated

OBJECTIVES

Several high-income countries have implemented a gender-neutral vaccination program against human papillomavirus (HPV) infections. The impact of a gender-neutral program (GNP) on parental intention to vaccinate their daughters has not been studied, especially in countries with low HPV vaccine coverage among girls.

PATIENTS AND METHODS

In July 2019, before a GNP was implemented in France (2021), the French National Cancer Institute (INCa) conducted a survey on HPV vaccine acceptance among parents of children aged 11-19 years living in France. In the sample of girls' parents (n = 1424 parents, 1726 girls), we investigated whether parents who declared no initial intention to have their daughter(s) vaccinated changed their minds after reading information including a male perspective on HPV consisting in description of HPV-related disease among men and in ascertainment of the fact that in some countries, the HPV vaccine is recommended for boys, after which they were once again asked about their intentions "if the vaccine were recommended to boys and girls alike".

RESULTS

As regards 295 (25.7 %) of the 1147 unvaccinated girls, their parents declared no intention to have them vaccinated, while 509 (44.4 %) were not sure. Among the parents of the 804 girls whose parents had not intended to have them vaccinated, 134 (16.7 %) changed their minds after reading about HPV among men. Fathers were more likely than mothers to change their minds, and finally intend to have their daughters vaccinated (adjusted relative risk, 1.74 [95 % confidence interval, 1.20,2.54]).

CONCLUSIONS

These results suggest that parents, and fathers in particular, could be more motivated to have their daughters vaccinated against HPV if the information with which they were provided included a male perspective and a recommendation of vaccination for boys as well as girls.

Associations of geographic-based socioeconomic factors and HPV vaccination among male and female children in five US states

BACKGROUND

We assessed whether five geographic-based socioeconomic factors (medically underserved area (MUA); healthcare provider shortage area (HPSA); persistent poverty; persistent child poverty; and social vulnerability index (SVI)) were associated with the odds of HPV vaccination initiation, series completion, and parental vaccine hesitancy, and whether the observed relationships varied by gender of the child.

METHODS

An online panel service, administered through Qualtrics®, was used to recruit parents of adolescents 9-17 years of age to complete a one-time survey in 2021. Coverage of the panel included five US states: Arkansas, Mississippi, Missouri, Tennessee, and Southern Illinois. Generalized estimating equation (GEE) models were used to assess population-level associations between five geographic-based socioeconomic factors (MUA; HPSA; persistent poverty; persistent child poverty; and SVI) and three HPV vaccination outcomes (initiation, series completion, and hesitancy). All GEE models were adjusted for age of child and clustering at the state level.

RESULTS

Analyses were conducted using responses from 926 parents about their oldest child in the target age range (9-17 years). The analytic sample consisted of 471 male children and 438 female children across the five states. In adjusted GEE models, persistent child poverty and HPSA were negatively associated with HPV vaccination initiation and series completion among female children, respectively. Among male children, high social vulnerability was negatively associated with HPV vaccine series completion. Additionally, persistent poverty and high social vulnerability were negatively associated with HPV vaccine hesitancy in male children.

CONCLUSIONS

The results of this cross-sectional study suggest that geographic-based socioeconomic factors, particularly, HPSA, persistent poverty, and SVI, should be considered when implementing efforts to increase HPV vaccine coverage for adolescents. The approaches to targeting these geographic factors should also be evaluated in future studies to determine if they need to be tailored for male and female children.

Updates on HPV Vaccination

Cervical cancer still poses a significant global challenge. Developed countries have mitigated this challenge by the introduction of structured screening programmes and, more recently, the HPV vaccine. Countries that have successfully introduced national HPV vaccination programmes are on course for cervical cancer elimination in a few decades. In developing countries that lack structured screening and HPV vaccination programmes, cervical cancer remains a major cause of morbidity and mortality. The HPV vaccine is key to addressing the disproportionate distribution of cervical cancer incidence, with much to be gained from increasing vaccine coverage and uptake globally. This review covers the history and science of the HPV vaccine, its efficacy, effectiveness and safety, and some of the considerations and challenges posed to the achievement of global HPV vaccination coverage and the consequent elimination of cervical cancer.

HPV Vaccination Training of Healthcare Providers and Perceived Self-Efficacy in HPV Vaccine-Hesitancy Counseling

HPV vaccine hesitancy is a key barrier to HPV vaccination. Using a population-based survey of HCPs practicing in Texas we determined the association between formal training of HCPs and perceived self-efficacy in counseling HPV vaccine-hesitant parents and adult patients. A total of 1283 HCPs completed the survey, with 879 providing vaccination services to pediatric patients and 1018 providing vaccination services to adult patients. Among HCPs included in this study, 405 of 577 (70%) and 315 of 505 (62%) perceived they were very/completely confident in counseling HPV vaccine-hesitant parents and adult patients, respectively. Compared to HCPs who received no training, those who received formal training in HPV vaccination promotion or counseling had 2.56 (AOR: 2.56; 95% CI:1.69-3.86) and 2.84 times higher odds (AOR: 2.84; 95% CI:1.87-4.33) of perceiving that they were very/completely confident in counseling HPV vaccine-hesitant parents and adult patients, respectively. Additionally, increasing years of practice and volume of patients seen were positively associated with being very/completely confident in counseling HPV vaccine-hesitant parents and adult patients. On the other hand, nurses were less likely than physicians to be very/completely confident in counseling HPV vaccine-hesitant parents. To increase HPV vaccination uptake, HCPs should receive tailored training to improve their self-efficacy in addressing HPV vaccine-hesitancy.
