Factors Associated with the HPV Vaccination among Korean Americans and Koreans: A Systematic Review

Turning the Health Equity Lens to Diversity in Asian American Health Profiles

The monolithic misrepresentation of Asian American (AsAm) populations has maintained assumptions that AsAm people are not burdened by health disparities and social and economic inequities. However, the story is more nuanced. We critically review AsAm health research to present knowledge of AsAm health profiles from the past two decades and present findings and opportunities across three topical domains: (a) general descriptive knowledge, (b) factors affecting health care uptake, and (c) effective interventions. Much of the literature emphasized underutilization of health care services; low knowledge and awareness among AsAms about health-related risk factors, prevention, diagnosis, and treatment; inadequate efforts by health systems to improve language access, provider-patient communication, and trust; and the critical roles of community- and faith-based organizations and leaders in health promotion initiatives. Future opportunities for AsAm health research will require adoption of and significant investment in community-engaged research infrastructure to increase representation, funding, and research innovation for AsAm communities.

Human papillomavirus (HPV) vaccination in males: Associations of HPV-related knowledge and perceptions with HPV vaccination intention among Korean mothers of boys

Objectives

Human papillomavirus (HPV) vaccination rates among males are suboptimal worldwide. In South Korea, little is known about parents' intention to vaccinate boys against HPV. Therefore, we examined the associations of HPV-related knowledge and perceptions with vaccination intention among Korean mothers of boys.

Methods

From August to December 2021, eligible mothers were surveyed about HPV-related knowledge, perceptions, and intention to vaccinate their sons against HPV. Mothers were categorized into no intention, contemplating, and intention to vaccinate groups. Using analysis of variance, we compared the groups' scores on the scales measuring HPV-related knowledge, attitudes, and beliefs. We conducted a multinomial logistic regression analysis to assess the associations between the variables and vaccination intention.

Results

Among 361 mothers, 43.9 % had no intention, 60.7 % were contemplating, and 4.4 % intended to vaccinate their sons. The mean percentage of correct answers on the HPV and vaccine knowledge scales were 52.5 % and 62.3 %, respectively. The mean scores on the HPV attitudes and beliefs subscales were significantly different. Higher scores on benefits (OR = 3.04, 95 % CI 1.96 - 4.70; OR = 3.94, 95 % CI 1.54 - 10.70) and influence (OR = 1.48, 95 % CI 1.03 - 2.13; OR = 2.97, 95 % CI 1.44 - 6.14) were associated with contemplating the vaccine and intending to vaccinate sons. Knowledge was not associated with mothers' vaccination intention.

Conclusions

Public health authorities and healthcare providers in Korea can use the results of this study to implement effective interventions that emphasize the importance of male HPV vaccination and encourage parent-son communication about the vaccine.

Factors affecting HPV vaccine uptake among ethnic minority adolescent girls: A systematic review and meta-analysis

Objective

Human papillomavirus (HPV) vaccination rates remain low among adolescent girls across ethnic minority groups that experience high incidences of HPV-related cervical cancer with poor outcomes. This systematic review aimed to synthesize the available evidence on the factors affecting HPV vaccination among ethnic minority adolescent girls.

Methods

Six databases (PubMed, OVID MEDLINE, EMBASE, CINAHL, PsycINFO, and Scopus) were searched from inception to October 17, 2022. Guided by the conceptual model of vaccine hesitancy, the factors affecting HPV vaccine uptake were descriptively synthesized and analyzed using meta-analyses.

Results

This review included 14 studies. The pooled uptake rate of at least one dose of HPV vaccine among ethnic minority adolescent girls was only 38% (95% confidence interval ​= ​0.22, 0.39). At individual level, age of adolescent girls, knowledge of HPV, perceived importance of HPV vaccination, and perceived risk of HPV infection promoted the vaccine uptake. Beliefs in conspiracy theories and lack of trust in the government and HPV vaccine discouraged the utilization. At social and policy levels, health professionals' recommendations, subjective norms, sexuality-related communication, and vaccine policies such as insurance coverage facilitated HPV vaccination. The religious and moral convictions regarding abstinence from sex until marriage negatively influenced the vaccine acceptance.

Conclusions

HPV vaccination among ethnic minority adolescent girls was influenced by multi-level factors that highlighted a combined effort, including culturally sensitive health education programmes, sexuality-related communication skills training, collaboration with religious organizations, debunking conspiracy theories in HPV vaccine, and promoting school-based vaccination programs, to increase the coverage.

The Relationships Between Social Media and Human Papillomavirus Awareness and Knowledge: Cross-sectional Study

BACKGROUND

Human papillomavirus (HPV) is the most common sexually transmitted infection. HPV can infect both females and males, and it can cause many cancers, including anal, cervical, vaginal, vulvar, and penile cancers. HPV vaccination rates are lower than vaccination rates within other national vaccination programs, despite its importance. Research literature indicates that people obtain health-related information from internet sources and social media; however, the association between such health-seeking behavior on social media and HPV-related behaviors has not been consistently demonstrated in the literature.

OBJECTIVE

This study aims to examine the association between social media usage and HPV knowledge and HPV awareness.

METHODS

This study analyzed public health data collected through the Health Information National Trends Survey (HINTS) conducted by the US National Cancer Institute. The analysis used data collected in 2020; in total, 2948 responses were included in the analysis. Six HPV-related questions were used to identify HPV awareness, HPV vaccine awareness, and HPV knowledge about HPV-related cancers. Four questions about social media usage and one question about online health information-seeking behavior were used to analyze the associations between social media usage and HPV-related behaviors. Initially, six logistic regressions were conducted using replicate weights. Based on the results, significant factors were included in a second set of regression analyses that also included demographic variables.

RESULTS

About half of the respondents were aware of HPV (68.40%), the HPV vaccine (64.04%), and the relationship between HPV and cervical cancer (48.00%). However, fewer respondents were knowledgeable about the relationships between HPV and penile cancer (19.18%), anal cancer (18.33%), and oral cancer (19.86%). Although social media usage is associated with HPV awareness, HPV vaccine awareness, and knowledge of cervical cancer, these associations were not significant after adjusting for demographic variables. Those less likely to report HPV awareness and knowledge included older participants, males, those with a household income of less than US $20,000, those with a formal education equal to or less than high school, or those who resided in a household where adults are not fluent in English.

CONCLUSIONS

After adjusting for demographic variables, social media use was not related to HPV knowledge and awareness, and survey respondents were generally not aware that HPV can lead to specific types of cancer, other than cervical cancer. These results suggest that perhaps a lack of high-quality information on social media may impede HPV awareness and knowledge. Efforts to educate the public about HPV via social media might be improved by using techniques like storytelling or infographics, especially targeting vulnerable populations, such as older participants, males, those with low incomes, those with less formal education, or those who reside in the United States but are not fluent in English.
