Statewide HPV Vaccine Initiation Among Adolescent Females in North Carolina

Background: Cervical cancer incidence in the United States may be greatly reduced through widespread human papillomavirus (HPV) vaccination. We estimated the statewide level of HPV vaccine initiation among adolescent girls in North Carolina and identified correlates of vaccine initiation. Methods: We used data from 617 parents of adolescent females from North Carolina who completed the population-based 2008 Child Health Assessment and Monitoring Program survey. Analyses used weighted multivariate logistic regression. Results: Overall, 31.3% of parents reported their daughters had received at least 1 dose of HPV vaccine. Vaccine initiation was higher among daughters aged 13 to 15 years (odds ratio [OR] = 2.03, 95% CI, 1.12–3.67) or 16 to 17 years (OR = 3.21, 95% CI, 1.76–5.86) compared with those 10 to 12 years old. Additional correlates of HPV vaccine initiation included the daughter having a preventive check-up in the last 12 months (OR = 5.09, 95% CI, 2.43–10.67), having received meningococcal vaccine (OR = 2.50, 95% CI, 1.55–4.01), or being from an urban area (OR = 1.81, 95% CI, 1.02–3.21). Among parents of unvaccinated daughters, intent to vaccinate in the next year was higher among those with daughters aged 13 to 17 years. Parents of unvaccinated non-Hispanic white daughters reported lower levels of intent to vaccinate within the next year compared with parents of unvaccinated daughters of other races. Conclusions: HPV vaccine initiation in North Carolina is comparable with other US areas. Potential strategies for increasing HPV vaccination levels include reducing missed opportunities for HPV vaccination at preventive check-ups and increasing concomitant administration of HPV vaccine with other adolescent vaccines.

Designing Messages to Motivate Parents To Get Their Preteenage Sons Vaccinated Against Human Papillomavirus

CONTEXT Human papillomavirus (HPV) vaccine, licensed for use in 9--26-year-olds, is most effective when given before sexual activity begins. HPV causes genital warts, is associated with several cancers and disproportionately affects racial and ethnic minorities. Parents are typically unaware of male HPV vaccine; messages that might motivate them to get their preteenage sons vaccinated are unexplored. METHODS Messages promoting vaccination of preteenage boys were designed and tested in 2009 and 2010. Five focus groups were conducted with 29 black parents of 11-12-year-old boys, recruited through three churches and a middle school in North Carolina, and a racially diverse sample of 100 parents of 9-13-year-old boys in a university-based adolescent health clinic was interviewed. A constant comparison method was used to code transcripts and interpret themes. Chi-square and t tests or analyses of variance were used to assess differences in quantitative data. RESULTS Focus group parents knew little about HPV in males. Although concerned about safety and cost, parents supported vaccination for their sons. They wanted to see racial diversity and both parents in motivational materials. In interviews, 89% of parents reported never having heard of male HPV vaccine. The largest proportion said that a message stressing the prevalence and possible consequences of HPV infection was the most motivating (32%); the design favored by the largest proportion (43%) showed two parents. CONCLUSIONS Messages that may most motivate parents to get preteenage boys vaccinated against HPV focus on infection risk and include images of parents with their sons.

Asking Mom: Formative Research for an HPV Vaccine Campaign Targeting Mothers of Adolescent Girls

Vaccination against the types of human papillomavirus (HPV) that cause about 70% of cervical cancers is approved for use in girls and women between 9 and 26 years of age and recommended routinely in 11–12-year-old girls. This article reports on the systematic theory-based formative research conducted to develop HPV vaccine messages for a campaign targeting racially diverse mothers of nonvaccinated 11–12-year-old girls in rural Southeastern United States. A consortium of 13 county health departments concerned about high rates of cervical cancer in their region relative to state and national averages initiated the campaign. The research examined behavioral determinants for vaccination decisions as well as mothers’ reactions to message frames and emotional appeals. On the basis of focus groups and intercept interviews (n = 79), the authors demonstrated how preproduction message research and production message testing were used to develop messages that would motivate mothers of preteen girls. Core emotional truths that emerged were a mothers instinct to protect her daughter from harm and to embrace aspirations for her daughters future. Mothers also reacted more positively to text about preventing cervical cancer than about preventing HPV, a sexually transmitted disease. Mothers preferred message concepts with photos of minorities and Caucasian mothers and daughters.

Intervention effects from a social marketing campaign to promote HPV vaccination in preteen boys.

OBJECTIVES Adoption of human papillomavirus (HPV) vaccination in the US has been slow. In 2011, HPV vaccination of boys was recommended by CDC for routine use at ages 11-12. We conducted and evaluated a social marketing intervention with parents and providers to stimulate HPV vaccination among preteen boys. METHODS We targeted parents and providers of 9-13 year old boys in a 13 county NC region. The 3-month intervention included distribution of HPV vaccination posters and brochures to all county health departments plus 194 enrolled providers; two radio PSAs; and an online CME training. A Cox proportional hazards model was fit using NC immunization registry data to examine whether vaccination rates in 9-13 year old boys increased during the intervention period in targeted counties compared to control counties (n=15) with similar demographics. To compare with other adolescent vaccines, similar models were fit for HPV vaccination in girls and meningococcal and Tdap vaccination of boys in the same age range. Moderating effects of age, race, and Vaccines for Children (VFC) eligibility on the intervention were considered. RESULTS The Cox model showed an intervention effect (β=0.29, HR=1.34, p=.0024), indicating that during the intervention the probability of vaccination increased by 34% in the intervention counties relative to the control counties. Comparisons with HPV vaccination in girls and Tdap and meningococcal vaccination in boys suggest a unique boost for HPV vaccination in boys during the intervention. Model covariates of age, race and VFC eligibility were all significantly associated with vaccination rates (p<.0001 for all). HPV vaccination rates were highest in the 11-12 year old boys. Overall, three of every four clinic visits for Tdap and meningococcal vaccines for preteen boys were missed opportunities to administer HPV vaccination simultaneously. CONCLUSIONS Social marketing techniques can encourage parents and health care providers to vaccinate preteen boys against HPV.

Prevention of Sexually Transmitted Diseases in an Era of Managed Care: The Relevance for Women

New directions in public health will inevitably result from the intersection of three high priority, yet overlapping, issues: 1) the increasing concerns for women’s health; 2) the perpetual challenges of sexually transmitted diseases (STDs); and 3) the emerging opportunities from managed care. With the explosion of various managed care delivery systems, policy makers need to consider how to use these organizations to improve health outcomes for women at risk for STDs.1 Although managed care is not a monolithic system, certain features of managed care organizations (MCOs) may lead to a greater capacity to prevent, screen, diagnose, and treat STDs in women.2 The challenge is what to preserve from the ‘‘old’’ mix of public clinics and private fee-for-service practices and what to emphasize within a ‘‘new’’ MCO system to produce a maximum impact on reducing sexually transmitted infections in women, their partners, and offspring. In this article, we first describe the unique association of women with STDs. We then explain the basic elements of our current public health system to prevent and treat STDs. Next, we address the possible ways that managed care can affect our current system. Finally, we conclude with recommendations for how to marshall the resources afforded by managed care to minimize STDs in women.

Communication technologies to improve HPV vaccination initiation and completion: A systematic review

OBJECTIVES This systematic review examines the effectiveness of communication technology interventions on HPV vaccination initiation and completion. METHODS A comprehensive search strategy was used to identify existing randomized controlled trials testing the impact of computer-, mobile- or internet-based interventions on receipt of any dose of the HPV vaccine. Twelve relevant studies were identified with a total of 38,945 participants. RESULTS The interventions were delivered using several different methods, including electronic health record (i.e. recall/reminder) prompts, text messaging, automated phone calls, interactive computer videos, and email. Vaccine initiation and completion was greater for technology-based studies relative to their control conditions. CONCLUSION There is evidence that interventions utilizing communication technologies as their sole or primary mode for HPV vaccination intervention delivery may increase vaccination coverage. PRACTICE IMPLICATIONS Communication technologies hold much promise for the future of HPV vaccination efforts, especially initiatives in practice-based settings.

Partnering With Middle School Students to Design Text Messages About HPV Vaccination

Human papillomavirus (HPV) vaccination is routinely recommended for U.S. adolescents ages 11 to 12 years, yet vaccine coverage remains low. Text message HPV immunization reminders to parents have been effective with increasing uptake, but text messages directly to adolescents in order to increase HPV vaccination uptake are unknown. The purpose of this study was to examine the acceptability of text messages about HPV vaccination and message preferences among adolescents. Middle school students (n = 43) assisted in designing text messages to promote HPV vaccine among their peers. Through seven focus groups and two in-class surveys, we assessed students’ knowledge of HPV vaccine, use of texting, and preferences for text messages and sources. The average age of participants was 13 years, and all were White (17 males, 26 females) in this rural setting. More than 70% used text messaging with a cell phone. The text message with the best composite score (M = 2.33, SD = 0.72) for likeability, trustworthiness, and motivation to seek more information was a gain frame emphasizing reduction in HPV infection if vaccinated against HPV. Text messages with lower scores emphasized threats of disease if not vaccinated. Participants (68%) preferred doctors as their information source. Text messaging to adolescents may be a strategy to improve HPV knowledge and vaccination.

Reducing Concurrent Sexual Partnerships Among Blacks in the Rural Southeastern United States: Development of Narrative Messages for a Radio Campaign

In the United States, heterosexual transmission of HIV infection is dramatically higher among Blacks than among Whites. Overlapping (concurrent) sexual partnerships promote HIV transmission. The authors describe their process for developing a radio campaign (Escape the Web) to raise awareness among 18–34-year-old Black adults of the effect of concurrency on HIV transmission in the rural South. Radio is a powerful channel for the delivery of narrative-style health messages. Through six focus groups (n = 51) and 42 intercept interviews, the authors explored attitudes toward concurrency and solicited feedback on sample messages. Men were advised to (a) end concurrent partnerships and not to begin new ones; (b) use condoms consistently with all partners; and (c) tell others about the risks of concurrency and benefits of ending concurrent partnerships. The narrative portrayed risky behaviors that trigger initiation of casual partnerships. Women were advised to (a) end partnerships in which they are not their partners only partner; (b) use condoms consistently with all partners; and (c) tell others about the risks of concurrency and benefits of ending concurrent partnerships. Messages for all advised better modeling for children.

Social marketing to promote HPV vaccination in pre-teenage children: Talk about a sexually transmitted infection

A significant barrier to the delivery of HPV vaccine is reluctance by both healthcare providers and parents to vaccinate at age 11 or 12, which may be considered a young age. This barrier has been called “vaccine hesitancy” in recent research. In this commentary, we suggest using social marketing strategies to promote HPV vaccination at the recommended preteen ages. We emphasize a critical public health message of a sexually transmitted infection (STI) as preventable and vaccination against HPV as a way to protect against its consequences. The message tackles the issue of vaccine hesitancy head on, by saying that most people are at risk for HPV and there is a way to prevent HPVs serious consequences of cancer. Our approach to this conversation in the clinical setting is also to engage the preteen in a dialog with the parent and provider. We expect our emphasis on the risk of STI infection will not only lead to increased HPV vaccination at preteen ages but also lay important groundwork for clinical adoption of other STI vaccines in development (HIV, HSV, Chlamydia, and Gonorrhea) as well as begin conversations to promote sexual health.

Immunization effects of a communication intervention to promote preteen HPV vaccination in primary care practices

OBJECTIVES HPV vaccination at the recommended ages of 11-12 is highly effective yet has stalled well below the goal of 80% of the population. We evaluated a statewide practice-based communication intervention (tools: brochures, posters, online training for providers and resources for parents, video game for preteens) to persuade parents, preteens and providers to vaccinate against HPV. The 9-month intervention started May 1, 2015. METHODS We compared vaccine initiation and completion rates over three 9-month periods (baseline, intervention, post-intervention) between practices enrolled in the intervention and a comparable comparison group. All practices reported to the North Carolina Immunization Registry (NCIR) and had at least 100 11- and 12-year-olds who had not completed the HPV vaccine series. Of 175 eligible practices, the 14 intervention practices included 19,398 individuals and the 161 comparison practices included 127,896 individuals. An extended Cox model was used to test the intervention effect. RESULTS The intervention had a significant effect on both initiation and completion during the intervention and post-intervention periods; the estimated hazard ratio (HR) for initiation was 1.17 (p = .004) during the intervention and 1.11 (p = .005) post-intervention. Likewise, completion during the intervention period was 17% higher in intervention practices, after controlling for baseline differences. This effect increased in the post-intervention period to 30% higher (p = .03). CONCLUSIONS Individuals in the intervention practices were 17% more likely to initiate and complete HPV vaccination than in the comparison practices during the intervention period and the effect was sustained post-intervention. This intervention is promising for increasing rates of HPV vaccination at ages 11-12.
