HPV Vaccination Champions: Evaluating a Technology-Mediated Intervention for Parents

The Emerging Landscape of Social Media Influencers in Public Health Collaborations: A Scoping Review

Social media content creators or "influencers" are an increasingly influential voice in the public discourse generally, including global perceptions and practices related to health. In response, public health entities are increasingly embracing social media influencers (SMIs) as potential health promotion collaborators. Despite burgeoning interest in the potential of these partnerships, research evaluating this strategy remains limited. To address this gap, we conducted a scoping review to characterize and describe the current landscape of health promotion collaborations with SMIs with a focus on current practices. A search of six electronic databases (PubMed, SCOPUS, Communication & Mass Media Complete, CINAHL Plus, Web of Science, and APA PsycINFO) revealed wide-ranging and inconsistent approaches to these partnerships, including their optimal practices, data reported, and their evaluation criteria. Among the 658 articles initially identified, 15 publications met our inclusion criteria, spanning 7 countries, 8 social media platforms, 11 distinct health topics, and 21 different outcome measures. Basic information necessary for comparing across interventions was often lacking. We noted a lack of consensus on what constitutes an SMI with 53% of included studies lacking any definition or criteria. Although SMIs offer substantial promise as an emerging opportunity for health promotion, particularly for populations that may be otherwise difficult to identify or reach, this review highlights how the current lack of standardized methodologies and metrics prevents meaningful comparisons between collaborations and evaluations of their effectiveness. Based on these findings, we propose four key criteria to aid practitioners in the implementation and evaluation of SMI collaborations.

#4Corners4Health Social Media Cancer Prevention Campaign for Emerging Adults: Protocol for a Randomized Stepped-Wedge Trial

BACKGROUND

Many emerging adults (EAs) are prone to making unhealthy choices, which increase their risk of premature cancer morbidity and mortality. In the era of social media, rigorous research on interventions to promote health behaviors for cancer risk reduction among EAs delivered over social media is limited. Cancer prevention information and recommendations may reach EAs more effectively over social media than in settings such as health care, schools, and workplaces, particularly for EAs residing in rural areas.

OBJECTIVE

This pragmatic randomized trial aims to evaluate a multirisk factor intervention using a social media campaign designed with community advisers aimed at decreasing cancer risk factors among EAs. The trial will target EAs from diverse backgrounds living in rural counties in the Four Corners states of Arizona, Colorado, New Mexico, and Utah.

METHODS

We will recruit a sample of EAs (n=1000) aged 18 to 26 years residing in rural counties (Rural-Urban Continuum Codes 4 to 9) in the Four Corners states from the Qualtrics' research panel and enroll them in a randomized stepped-wedge, quasi-experimental design. The inclusion criteria include English proficiency and regular social media engagement. A social media intervention will promote guideline-related goals for increased physical activity, healthy eating, and human papillomavirus vaccination and reduced nicotine product use, alcohol intake, and solar UV radiation exposure. Campaign posts will cover digital and media literacy skills, responses to misinformation, communication with family and friends, and referral to community resources. The intervention will be delivered over 12 months in Facebook private groups and will be guided by advisory groups of community stakeholders and EAs and focus groups with EAs. The EAs will complete assessments at baseline and at 12, 26, 39, 52, and 104 weeks after randomization. Assessments will measure 6 cancer risk behaviors, theoretical mediators, and participants' engagement with the social media campaign.

RESULTS

The trial is in its start-up phase. It is being led by a steering committee. Team members are working in 3 subcommittees to optimize community engagement, the social media intervention, and the measures to be used. The Stakeholder Organization Advisory Board and Emerging Adult Advisory Board were formed and provided initial input on the priority of cancer risk factors to target, social media use by EAs, and community resources available. A framework for the social media campaign with topics, format, and theoretical mediators has been created, along with protocols for campaign management.

CONCLUSIONS

Social media can be used as a platform to counter misinformation and improve reliable health information to promote health behaviors that reduce cancer risks among EAs. Because of the popularity of web-based information sources among EAs, an innovative, multirisk factor intervention using a social media campaign has the potential to reduce their cancer risk behaviors.

Motives and attitudes of parents toward HPV vaccination: Results from the initial period of HPV vaccine rollout in Serbia

Human papillomavirus (HPV) infection is one of the most common viral infections in sexually active population worldwide, and is the main cause of cervical cancer, which is the fourth most common cancer among women. Serbia ranks third in incidence and mortality rate of cervical cancer in Europe. We conducted a cross-sectional study considering parents' motivation for the HPV vaccination of their children. Statistical analysis included descriptive statistics and a logistic regression model. We found that the strongest motive was "Recommendation from paediatrician" (20.2%), followed by the attitude that HPV vaccine protects against cancers in different localization (15.4%), the motive "It is better to vaccinate a child than expose them to potential risk of HPV infection" (13.3%) and "Feeling anxiety due to a possible infection and cancer in the child" (13.1%). For those parents that vaccinated their child for some other strongest motive, reasons like "Vaccine is free of charge", "Recommendation from friends and family" and motive "My child received all obligatory vaccines, so I want to receive this one as well", were significantly more frequently selected. In the group where paediatricians' recommendation was not a motive for accepting the HPV vaccine, the largest percentage of parents (89.6%) selected motive "HPV vaccine protects against cancers in different localization" and the motive "It is better to vaccinate a child than expose them to potential risk of HPV infection" (78.1%). Paediatrician's recommendation is very important for parents' decision to vaccinate, however, other motives also influenced and had significance in making the parents' decision to vaccinate their children against HPV. Encouraging trust in public health authorities in Serbia, highlighting the advantages of the HPV vaccine and further encouraging healthcare workers to give stronger recommendations can increase the HPV vaccine uptake. Finally, we provided the basis to create more targeted messages that will empower parents to vaccinate their children.

A Descriptive Study of Maternal Vaccination Uptake, Attitudes, and Beliefs in Pregnancy Among Persons Delivering at an Urban Safety Net Hospital

Objective

To estimate uptake of influenza, tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap), and COVID-19 vaccines during pregnancy and describe vaccine attitudes and beliefs among predominantly racial and ethnic minority individuals delivering at a publicly funded hospital.

Methods

We collected survey and electronic medical record data for English-speaking postpartum individuals who delivered a live-born infant from July 7, 2022, through August 21, 2022, and agreed to participate in our study. The 58-item survey included questions about general vaccine attitudes and beliefs as well as vaccine-specific questions. We calculated rates of influenza, Tdap, and COVID-19 vaccinations and compared distributions of survey responses by number (no vaccines, one vaccine, or two or three of the recommended vaccines) and type of vaccines received during pregnancy.

Results

Of the 231 eligible individuals, 125 (54.1%) agreed to participate. Rates of influenza, Tdap, and COVID-19 vaccination were 18.4%, 48.0%, and 5.6% respectively. A total of 61 (48.8%) did not receive any recommended vaccines during pregnancy, 40 (32.0%) received one vaccine, and 24 (19.0%) received two or three vaccines. Approximately 66.1% of the no vaccine group, 81.6% of the one vaccine group, and 87.5% of the two or three vaccine group strongly agreed or agreed that they trusted the vaccine information provided by their obstetrician or midwife. While most (>69.2%) agreed that the vaccine-preventable diseases were dangerous for pregnant women, only 24.0%, 29.3%, and 40.3% agreed that they were worried about getting influenza, whooping cough, or COVID-19, respectively, while pregnant.

Discussion

Vaccine uptake in our population was low and may be due, in part, to low perceived susceptibility to vaccine-preventable diseases. Obstetricians and midwives were trusted sources of vaccine information, suggesting that enhanced communication strategies could be critical for addressing maternal vaccine hesitancy, particularly in communities of color justifiably affected by medical mistrust.

Human Papillomavirus Vaccine Hesitancy in the United States

Although the US Advisory Committee on Immunization Practices recommends vaccinating adolescents against the human papillomavirus (HPV) to prevent HPV-associated cancers, vaccine initiation and completion rates are suboptimal. Parental and provider hesitancy contributes significantly to low HPV vaccine uptake. This review describes sources of HPV vaccine hesitancy using a World Health Organization framework that categorizes determinants of vaccine hesitancy as follows: contextual factors (historical, sociocultural, environmental, or political factors), individual and group factors (personal perception or influences of the social/peer environment), and vaccine/vaccination-specific issues (directly related to vaccine or vaccination).

Digital Health Interventions to Improve Adolescent HPV Vaccination: A Systematic Review

Digital technologies are being increasingly utilized in healthcare to provide pertinent and timely information for primary prevention, such as vaccination. This study aimed to conduct a systematic review to describe and assess current digital health interventions to promote HPV vaccination among adolescents and parents of adolescents, and to recommend directions for future interventions of this kind. Using appropriate medical subject headings and keywords, we searched multiple databases to identify relevant studies published in English between 1 January 2017 and 31 July 2022. We screened and selected eligible studies for inclusion in the final analysis. We reviewed a total of 24 studies, which included interventions using text messages (4), mobile apps (4), social media and websites (8), digital games (4), and videos (4). The interventions generally improved determinants of HPV vaccination, such as HPV-related knowledge, vaccine-related conversations, and vaccination intentions. In particular, text message and social media interventions targeted improved vaccine uptake behaviors, but little meaningful change was observed. In conclusion, digital health interventions can cost-effectively provide education about HPV vaccination, offer interactive environments to alleviate parental vaccine hesitancy, and ultimately help adolescents engage in HPV vaccine uptake.

Healthcare providers' practice protocols, strategies, and needed tools to address parental HPV vaccine hesitancy: An exploratory study

Parental hesitancy related to human papillomavirus (HPV) vaccines has increased during the pandemic, and there is a call to action by the National HPV Vaccination Roundtable to improve vaccination rates. While there are evidence-based strategies available to address parental hesitancy, there are few clear guidelines on how to engage parents to build confidence in the HPV vaccine within the clinical settings. The purpose of this investigation is to explore practice protocols, individual provider strategies, and perceived tools needed to address HPV vaccine hesitant parents from the perspective of providers during the COVID-19 pandemic in the United States. Fifteen healthcare providers participated in qualitative, semi-structured interviews between May 2021 and March 2022. An inductive, qualitative content analysis approach was used to analyze the data. Five themes were described: 1) Provider experiences engaging with HPV vaccine hesitant parents; 2) Existing protocols in the clinics to address HPV vaccine hesitant parents; 3) Strategies used by providers to address parental HPV vaccine hesitancy; 4) Sample message content used by providers to address parental HPV vaccine concerns; and 5) Perceived strategies and tools needed to address parental vaccine hesitancy. Recommendations to address parental hesitancy include recommending HPV vaccinationat 9  years, using a strong recommendation and continued discussion, applying evidence-based approaches and/or promising strategies, linking parents to credible outside sources, and ongoing follow-up if delayed or declined. These findings can be used by researchers and clinicians to improve strategies and messages to inform the development of a protocol to standardize encounters and communication for patient-parent-provider encounters that can influence parental decision-making around HPV vaccine uptake.

HPV and COVID-19 vaccines: Social media use, confidence, and intentions among parents living in different community types in the United States

Our study measured parental confidence and intention/uptake of two adolescent vaccines (HPV and COVID-19), focusing on differences among community types including urban, suburban, and rural. Although social media provides a way for misinformation to spread, it remains a viable forum for countering misinformation and engaging parents with positive vaccine information across community types. Yet, little is understood about differences in social media use and vaccine attitudes and behaviors for parents living in rural, suburban and urban areas. We sought to determine how to better reach parents living in different community types with targeted social media channels and messaging. In August 2021, we used a cross-sectional survey programmed in Qualtrics to collect data from 452 parents of children ages 9 to 14 living in different community types across the United States. Participants came from a survey panel maintained by CloudResearch. Survey questions asked about demographics, political affiliation, community type, social media use, health and vaccine information sources, and attitudes and behaviors regarding the HPV and COVID-19 vaccines. Our sample of parents (n = 452) most frequently used Facebook (76%), followed by YouTube (55%), and Instagram (43%). When comparing social media use by community type, parents used the top platforms at similar rates. Social media use was associated with vaccine confidence and intention/uptake in unadjusted models but not in adjusted models. Further, there were no significant differences in HPV vaccine confidence or intention/uptake by community type (i.e., rural, suburban, urban). For the COVID-19 vaccine, parents in rural communities were less likely to have vaccine confidence and intention/uptake in the unadjusted model. For both HPV and COVID-19 vaccines, political affiliation was the only common factor associated with both vaccine confidence and intention/uptake. Parents who identified as Democrat compared to Republican had greater confidence in the vaccines and had higher odds of vaccine intention/uptake for their children. Although rurality has been associated with vaccine confidence in the past we did not find that in our study. Instead, political affiliation appeared to explain most of the variation in vaccine confidence and intention/uptake, suggesting that more research is needed to identify best practices for using social media to reach parents with different political beliefs.

Sources of Information and Communication About HPV Among Chinese Students Attending U.S. Colleges: Implications for Culturally Appropriate Strategies

INTRODUCTION

Little is known about human papillomavirus (HPV) information sources and communication among Chinese students attending U.S. colleges. We assessed information sources and communication about HPV and HPV vaccines among this population.

METHODOLOGY

A cross-sectional design with 449 participants was conducted by using a questionnaire and snowball sampling. Summary statistics and multiple logistic regression were used.

RESULTS

The most common sources of HPV information included the internet and friends. Communication about HPV occurred most frequently among friends, family, and health professionals. Those who had better HPV knowledge and attitudes and were vaccinated against HPV were more likely to use internet, friends, family, and health professionals as their information sources.

DISCUSSION

Because the internet, friends, and families are likely sources for HPV information and communication, future internet-based culturally appropriate education should offer information not only to Chinese students but also to their social circles. Cultural beliefs may affect HPV prevention and should be examined.
