Allen JD, Abuelezam NN, Rose R, Isakoff K, Zimet G, Fontenot HB. HPV vaccine behaviors and intentions among a diverse sample of women aged 27-45 years: implications for shared clinical decision-making. BMC Public Health 2024; 24:2154. [PMID: 39118089 PMCID: PMC11308683 DOI: 10.1186/s12889-024-18740-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Accepted: 04/29/2024] [Indexed: 08/10/2024] Open
Abstract
BACKGROUND The Advisory Committee on Immunization Practices issued a shared clinical decision-making (SCDM) recommendation for HPV vaccination in persons aged 27-45. Since expanded eligibility for the vaccine was issued, little information has been available about HPV vaccine behaviors and intentions among women in this age group. METHODS We conducted a cross-sectional online survey among women aged 27-45 years recruited through a Qualtrics™ respondent panel (N = 324) to answer the following questions (1) What is the prevalence of HPV vaccination among a diverse sample of adult women aged 27-45 years? (2) What are the characteristics of those who have or have not previously been vaccinated? and (3) What factors are associated with the intention to obtain the HPV vaccine among those who had never been vaccinated? Multivariable logistic regression analyses estimated adjusted odds ratios (AORs) and 95% confidence intervals (95% CIs). RESULTS Only 31.1% had at least one dose of the HPV vaccine. In multivariable analyses, those more likely to have been vaccinated were younger and were more likely to believe that the vaccine was effective. Of those unvaccinated or unsure, 54.8% indicated they were likely to get vaccinated in the future. Factors associated with future vaccine intention (compared to those not intending) included beliefs about vaccine testing, perceived likelihood of HPV infection, greater comfort in asking one's provider for vaccination, and prior negative healthcare experiences. CONCLUSIONS Our findings suggest that many women in this age group are interested in HPV vaccination. While the recommendation is for SCDM rather than routine vaccination for all women in this age group, efforts to promote informed decision-making among mid-adult women may include educating women about the rigorous vaccine testing and approval process, their risk factors for HPV infection, and encouraging them to engage in SCDM with their medical providers. Targeted efforts to reach women who have had negative experiences with healthcare may also be needed.

Exploration of individual socioeconomic and health-related characteristics associated with human papillomavirus vaccination initiation and vaccination series completion among adult females: A comprehensive systematic evidence review with meta-analysis. Vaccine 2024:S0264-410X(24)00601-7.

Abstract
INTRODUCTION Human papillomavirus (HPV) vaccination rates among females are lower than the World Health Organization target and vaccination rates specifically among adult females are even much lower. METHODS We systematically evaluated individual socioeconomic and health-related characteristics associated with HPV vaccination initiation and vaccination series completion among adult females (PROSPERO: CRD42023445721). We performed a literature search on December 14, 2022, and supplemented the search on August 1, 2023. We pooled appropriate multivariable-adjusted results using an inverse variance random-effects model and expressed the results as odds ratios with associated 95 % confidence intervals. A point pooled significantly increased/decreased odds of 30-69 % was regarded to be strongly associated, and ≥ 70 % was very strongly associated. RESULTS We included 63 cross-sectional studies. There were strongly increased odds of vaccination initiation among White women compared with Black or Asian women, and those with higher education, health insurance, a history of sexually transmitted infection (STI), receipt of influenza vaccination in the preceding year, not married/cohabiting, not smoking, using contraception, and having visited a healthcare provider in the preceding year. We observed very strongly increased odds of vaccination initiation among those younger and having been born in the country of study. Similarly, there were strongly increased odds of completing the vaccination series for the same variables as initiating vaccination, except for higher education, prior STI, smoking and contraception use. Additional variables associated with strongly increased odds of vaccination series completion not seen in initiation were higher annual household income, being lesbian/bisexual, and having a primary care physician. We observed very strongly increased odds of vaccination series completion similar to vaccination initiation but including for White compared with Black women, higher education, and prior cervical cancer screening. CONCLUSIONS These individual characteristics may be the key to identifying women at increased risk of not being vaccinated against HPV and could inform targeted messaging to drive HPV vaccination.

Abstract
Objective: To identify facilitators and barriers to human papillomavirus (HPV) vaccination among college students.Methods: A cross-sectional survey with college students (N = 306) between the ages of 18 and 26 was conducted using a computer-delivered survey via iPad. A survey was designed to assess HPV/HPV vaccine-related knowledge, beliefs, and vaccination practices.Results: Low completion rates for the HPV vaccination series (females: 28.9%; males: 11.5%) were observed among college students. The compliance was lower among students who were black American and did not speak English at home. In contrast, the compliance was higher among those who had received any recommendation for HPV vaccination, those with higher knowledge about HPV and HPV vaccine, and higher perceived benefits of vaccination.Conclusions: Increasing knowledge of HPV infection, including the benefits of HPV vaccination and health care providers recommending the HPV vaccine, may increase HPV vaccination among college students and reduce the incidence of the disease.

Abstract
Recent findings suggest that the rate of certain cancers can be reduced by increasing human papillomavirus (HPV) vaccination coverage, resulting in considerable research interest on the antecedents of HPV vaccine receipt to identify avenues to promote vaccination. The current article continues this stream of research by (1) studying the three HPV vaccination outcomes of willingness, receipt, and word-of-mouth, (2) investigating the antecedent effects of sociodemographic characteristics, health insurance status, provider conversation, and political orientation, and (3) testing the mediating role of vaccine hesitancy dimensions using a recently developed conceptualization. We achieve these goals by conducting a cross-sectional study with 404 participants (Agemean = 37.64; AgeSD = 14.91; 57% female; 72% white; 100% located in U.S.). Our results show that provider conversations and political orientation had the most consistent and strong effects of the personal characteristics, whereas perceptions that vaccines pose health risks and perceptions that vaccines are not needed for healthy individuals produced the most consistent and strong effects of the vaccine hesitancy dimensions. Other personal characteristics and vaccine hesitancy dimensions also produced intermittent significant effects, including age, education, and race. Together, these results support that personal characteristics and vaccine hesitancy dimensions relate to a broader range of outcomes associated with HPV vaccination than previously known, and these results also support that the recently developed conceptualization of vaccine hesitancy is apt for understanding HPV vaccine perceptions. Our discussion concludes with highlighting avenues for future research and practice that can leverage our discovered relations to improve HPV vaccination outcomes.

Abstract
PURPOSE FOR REVIEW This perspective piece has two goals: first, to describe issues related to artificial intelligence-based applications for cancer control as they may impact health inequities or disparities; and second, to report on a review of systematic reviews and meta-analyses of artificial intelligence-based tools for cancer control to ascertain the extent to which discussions of justice, equity, diversity, inclusion, or health disparities manifest in syntheses of the field's best evidence. RECENT FINDINGS We found that, while a significant proportion of existing syntheses of research on AI-based tools in cancer control use formal bias assessment tools, the fairness or equitability of models is not yet systematically analyzable across studies. Issues related to real-world use of AI-based tools for cancer control, such as workflow considerations, measures of usability and acceptance, or tool architecture, are more visible in the literature, but still addressed only in a minority of reviews. Artificial intelligence is poised to bring significant benefits to a wide range of applications in cancer control, but more thorough and standardized evaluations and reporting of model fairness are required to build the evidence base for AI-based tool design for cancer and to ensure that these emerging technologies promote equitable healthcare.

The Role of Faith-Based Organizations in Improving Vaccination Confidence & Addressing Vaccination Disparities to Help Improve Vaccine Uptake: A Systematic Review. Vaccines (Basel) 2023; 11:vaccines11020449. [PMID: 36851325 PMCID: PMC9966262 DOI: 10.3390/vaccines11020449] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 02/09/2023] [Accepted: 02/12/2023] [Indexed: 02/18/2023] Open
Abstract
The COVID-19 pandemic underscored the importance of vaccination to support individual health across the life-course, with vaccination playing a central strategy role in mitigating transmission and disease. This required unprecedented mobilization and coordination across all sectors to meet people where they are, enable equitable access, and build vaccination confidence. A literature search was conducted with combinations of the keywords and variations of vaccination and faith-based organizations (FBOs). Search inclusion criteria were: (1) FBO programs that supported public health emergency efforts, including vaccination efforts as the primary outcome; and (2) articles written in English language. A total of 37 articles met inclusion criteria (n = 26 focused on general public health campaigns, n = 11 focused on vaccination efforts). The findings related to public health campaigns fell into four themes: FBO's ability to (1) tailor public health campaigns; (2) mitigate barriers; (3) establish trust; and (4) disseminate and sustain efforts. The findings related to vaccine uptake efforts fell into three themes: (1) pre-pandemic influenza and HPV vaccination efforts, (2) addressing vaccine disparities in minority communities, and (3) enabling COVID-19 vaccination. This review demonstrated that FBOs have a vital role in both public health campaigns and vaccination initiatives to support high vaccine uptake and confidence.

Knowledge, attitudes, and practices towards HPV vaccination among reproductive age women in a HIV hotspot in the US. PLoS One 2023; 18:e0275141. [PMID: 36656804 PMCID: PMC9851547 DOI: 10.1371/journal.pone.0275141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Accepted: 12/30/2022] [Indexed: 01/20/2023] Open
Abstract
BACKGROUND Human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the US, responsible for cervical cancer and increased risk of Human Immunodeficiency Virus (HIV) acquisition. Despite an effective HPV vaccine, women's HPV vaccination coverage and rates remain far below desired levels. This study aimed to evaluate HPV knowledge, attitudes, and vaccination practices as well as factors associated with HPV vaccination among women of reproductive age living in Miami, Florida, a Southern US city with a high incidence of STIs and low HPV vaccination coverage. METHODS From April to June 2022, 100 HIV-negative, cisgender, sexually active women aged 18-45 years were recruited from the Miami community. Participants completed validated questionnaires using REDCap© electronic surveys, assessing socio-demographics and sexual behaviors; HPV knowledge, screening, vaccination practices; barriers and motivators to HPV vaccination. A cumulative HPV knowledge score (HPV score) was generated. Factors associated with HPV vaccination were analyzed by Chi-square, Fisher's exact test, studentized t-test, and multivariate logistic regression (MLR). RESULTS A total of 100 participants were enrolled, and 84 who knew their vaccination status were included in the analysis. Of these, 43 reported receiving at least 1 HPV vaccine dose (vaccinated group) and 41 reported never being vaccinated (unvaccinated group). Mean age was 24.7 (SD 4.03) years for the vaccinated group and 31.4 (SD 8.33) for the unvaccinated group. Mean HPV score was 18.9/29 (SD 6.05) for the vaccinated group and 9.1/29 (SD 8.82) for the unvaccinated group. Amongst vaccinated participants, 76.74% reported a history of HPV/Pap smear screening vs 87.80% in the unvaccinated group. Barriers to HPV vaccination included: 14.6% low-risk perception, 29.3% healthcare barriers, and 46.3% vaccine hesitancy and personal beliefs. Motivators t HPV vaccination included: risk perception and vaccine beliefs (71.42%), healthcare-related (60.71%) and social motivators (55.95%). In the first MLR, one-point increases in HPV score were significantly associated with higher odds of HPV vaccination until an HPV score of 16, and a one-year increase in age was associated with a 16% lower odds of HPV vaccination (aOR = 0.84, 95% CI [0.72, 0.99]; p = 0.035). Contraception use was also associated with HPV vaccination (aOR 8.36 (95% CI [1.41, 49.62]; p = 0.020). Race, ethnicity, college education status, and number of sexual partners were not significant predictors of HPV vaccination. In the second MLR evaluating vaccination motivators as predictors of HPV vaccination, we found that individuals who were motivated by healthcare had 3.03 (95% CI [1.02, 9.00]; p = 0.046) times the odds of HPV vaccination compared to individuals without healthcare-related motivators. CONCLUSION Findings suggest suboptimal HPV knowledge and low vaccination rates among women of reproductive age. Public health efforts should focus on increasing basic HPV knowledge among women with little-to-no HPV knowledge to increase vaccine uptake.

Abstract
Approximately one-quarter of annual global cervical cancer deaths occur in India, possibly due to cultural norms promoting vaccine hesitancy. We sought to determine whether people of Indian ancestry (POIA) in the USA exhibit disproportionately lower human papilloma virus (HPV) vaccination rates than the rest of the US population. We utilised the 2018 National Health Interview Survey to compare HPV vaccine initiation and completion rates between POIA and the general US population and determined factors correlating with HPV vaccine uptake among POIA. Compared to other racial groups, POIA had a significantly lower rate of HPV vaccination (8.18% vs. 12.16%, 14.70%, 16.07% and 12.41%, in White, Black, Other Asian and those of other/mixed ancestry, respectively, P = 0.003), but no statistically significant difference in vaccine series completion among those who received at least one injection (3.17% vs. 4.27%, 3.51%, 4.31% and 5.04%, P = 0.465). Among POIA, younger individuals (vs. older), single individuals (vs. married), those with high English proficiency (vs. low English proficiency), those with health insurance and those born in the USA (vs. those born outside the USA) were more likely to obtain HPV vaccination (P = 0.018, P = 0.006, P = 0.029, P = 0.020 and P = 0.019, respectively). Public health measures promoting HPV vaccination among POIA immigrants may substantially improve vaccination rates among this population.

Trends in the Utilization of Human Papillomavirus Vaccines and the Incidence of Malignant Cervical Cancer in Women and Teenagers: A Secondary Analysis. Healthcare (Basel) 2022; 10:healthcare10071211.

Abstract
Background: Human papillomavirus (HPV) is a sexually transmitted infection, and HPV types 16 and 18 are responsible for approximately 66% of all U.S. cervical cancer cases in women. The quadrivalent HPV vaccine was licensed in mid-2006, and it was designed to target and protect against HPV types 6, 11, 16, and 18. The aim of this study is to examine the utilization rate of the HPV vaccine, and the trends and incidence rate of malignant cervical cancer across the United States. Methods: This study utilized data from Surveillance, Epidemiology, and End Results (SEER) and the National Immunization Survey’s (NIS) teenage datasets across select years. For the SEER survey, the modification for confidence intervals by Tiwari et al., 2006, was utilized to obtain the incidence rate per 100,000, so that it could be age-adjusted for the 2000 U.S. standard population, as noted in the data provided by the U.S. Census. The dates examined started in the year 2000 and ended in 2017. For the NIS-Teen survey, the public-use data file was used, and a point estimate (%), with a 95% confidence interval, was performed to examine the trends in HPV vaccine utilization across the U.S. adolescent female population from the years 2007 to 2019. Results: This study found that the rate of diagnosis had been falling over the nearly two decades examined in this study. Implications: This study would support current efforts to encourage the utilization of HPV vaccines that are currently in the vaccination schedule rotation, and to illustrate the importance of completing all doses of the three-step series.

Abstract
PURPOSE OF REVIEW To examine the status of racial and ethnic inequalities in fertility care in the United States (U.S.) at inception of 2022. This review highlights addressable underpinnings for the prevalent differentials in access to and utilization of infertility treatments and underscores gaps in preventive care as key contributors to racial and ethnic disparities in risk burden for subfertility and infertility. RECENT FINDINGS Significant gaps in access to and utilization of fertility care are consistently reported among racial and ethnic minorities, particularly Black and Hispanic women. Access to and utilization of contraceptives, human papilloma virus vaccination rates, preexposure prophylaxis use, and differentials in treatment of common gynecologic disorders are relevant to the prevalent racial and ethnic disparities in reproductive health. The spectrum of differential in reproductive wellness and the magnitude of reproductive health burden afflicting racial minorities in the U.S. raise concerns regarding systemic and structural racism as plausible contributors to the prevalent state of affairs. SUMMARY Despite efforts to reform unequal reproductive health practices and policies, racial and ethnic disparities in fertility care are pervasive and persistent. In addition to measures aimed at reducing barriers to care, societal efforts must prioritize health disparity research to systematically examine underpinnings, and addressing structural racism and interpersonal biases, to correct the prevalent racial inequities and mitigate disparities.

[PMID: 35344774 DOI: 10.1016/j.socscimed.2022.114871] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Revised: 01/24/2022] [Accepted: 02/25/2022] [Indexed: 10/18/2022]
Abstract
We investigated how gender identity, sexual orientation, and race/ethnicity intersect to shape the social epidemiology of HPV vaccination initiation among U.S. college students. Cross-sectional survey data were from the National College Health Assessment (Fall, 2019-Spring, 2020; N = 65,047). We conducted an intersectional Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy by nesting participants within 36 social strata defined using gender identity, sexual orientation, and race/ethnicity. Bayesian multilevel logistic regression models with random intercepts for social strata were fit for HPV vaccination initiation. Intersectional models adjusted for the additive main effects to isolate intersectional interactions, controlling for age and geographic region. Social strata that included cisgender men, transgender women, and non-binary assigned-male-at-birth individuals and strata that included racial/ethnic minorities had a significantly lower likelihood of HPV vaccination initiation relative to strata including cisgender women and non-Hispanic White individuals, respectively, while strata including lesbian/gay and bisexual/pansexual/queer individuals had a significantly higher likelihood of HPV vaccination initiation relative to strata including heterosexual individuals. We also observed substantial between-stratum inequities in the predicted prevalence of HPV vaccination initiation, with estimates ranging from 59.2% for heterosexual, racial/ethnic minority, cisgender men to 87.1% for bisexual/pansexual/queer, racial/ethnic minority, non-binary assigned-female-at-birth individuals. That being said, the majority of the observed between-stratum variance was driven by additive rather than intersectional interaction effects and the discriminatory accuracy of intersectional stratification with respect to predicting HPV vaccination initiation was low. Collectively, our findings point to a need for more universal guidelines and clinician recommendations that promote HPV vaccine uptake for all adolescents, regardless of race/ethnicity, gender identity, sex-assigned-at-birth, or sexual orientation; however, utilizing an intersectional lens will ensure that resulting public health interventions address inequities and center the needs and experiences of multiply marginalized adolescents.

A Real-world Claims Data Analysis of Meningococcal Serogroup B Vaccine Series Completion and Potential Missed Opportunities in the United States. Pediatr Infect Dis J 2022; 41:e158-e165. [PMID: 35086118 PMCID: PMC8920016 DOI: 10.1097/inf.0000000000003455] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 12/30/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND In the United States, meningococcal serogroup B (MenB) vaccination is recommended for 16-23-year-olds based on shared clinical decision-making. We estimated series completion among individuals initiating MenB vaccination for the 2 available vaccines: MenB 4-component (MenB-4C, doses at 0 and ≥1 month) and MenB factor H binding protein (MenB-FHbp, doses at 0 and 6 months). METHODS This retrospective health insurance claims data analysis included 16-23-year-olds who initiated MenB vaccination (index date) during January 2017 to November 2018 (MarketScan Commercial Claims and Encounters Database) or January 2017 to September 2018 (MarketScan Multi-State Medicaid Database) and had continuous enrollment for ≥6 months before and ≥15 months after index. The main outcome was MenB vaccine series completion within 15 months. Among noncompleters, preventive care/well-child and vaccine administrative office visits were identified as potential missed opportunities for series completion. Robust Poisson regression models identified independent predictors of series completion. RESULTS In the Commercial (n = 156,080) and Medicaid (n = 57,082) populations, series completion was 56.7% and 44.7%, respectively, and was higher among those who initiated MenB-4C versus MenB-FHbp (61.1% versus 49.8% and 47.8% versus 33.9%, respectively; both P < 0.001). Among noncompleters, 40.2% and 34.7% of the Commercial and Medicaid populations, respectively, had ≥1 missed opportunity for series completion. Receipt of MenB-4C and younger age were independently associated with a higher probability of series completion. CONCLUSIONS Series completion rates were suboptimal but were higher among those who initiated MenB-4C. To maximize the benefits of MenB vaccination, interventions to improve completion and reduce missed opportunities should be implemented.

Abstract
The present update is a reassessment of the 2018 'Guidelines for HPV-DNA Testing for Cervical Cancer Screening in Brazil' (Zeferino et al.)9, according to the changes observed in new international guidelines and knowledge updates. The most relevant and recent guidelines were assessed. Questions regarding the clinical practice were formulated, and the answers considered the perspective of the public and private sectors of the Brazilian health system. The review addressed risk-based strategies regarding age to start and stop screening, the use of cytology and colposcopy to support management decisions, treatment, follow-up strategies, and screening in specific groups, including vaccinated women. The update aims to improve the prevention of cervical cancer and to reduce overtreatment and the misuse of HPV testing.

[PMID: 33942195 DOI: 10.1007/s10508-020-01900-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Revised: 11/22/2020] [Accepted: 12/03/2020] [Indexed: 06/12/2023]
Abstract
In the U.S., human papillomavirus (HPV) vaccination has been recommended for individuals up to age 26, although the vaccination is currently approved for all people up to the age of 45. This research sought to explore HPV vaccination disparities by age with subgroup analysis by gender identity and sexual orientation groups, as well as sociodemographic factors that may serve as barriers to or facilitators of vaccination. This study used data from the 2018 Behavioral Risk Factor Surveillance System. Only data for individuals who reported their gender identity, sexual orientation, and HPV vaccination status were included in the analytic sample (n = 7330). HPV vaccination rates for this sample were low, as only 18.2% (n = 1332) of the sample had received the HPV vaccination. These low rates of vaccination were similar across all subsamples: cisgender men (9.8%, n = 343), cisgender women (25.8%, n = 985), heterosexuals (17.5%, n = 1197), lesbian women or gay men (20.8%, n = 40), and bisexuals (30.8%, n = 95). In multivariable logistic regression models, younger participants (18-34) were more likely to report receiving the HPV vaccination across all subsamples. Further modeling indicated several common factors associated with higher odds of vaccination: living in a metropolitan area, having insurance coverage, and having at least one provider. Understanding vaccination disparities, as well as vaccination facilitators and barriers, is important to inform policy and program efforts. This is especially significant for adults between the ages of 35 and 44 who were excluded from the initial vaccination recommendations but are vulnerable due to changing cultural norms, including delayed marriage, nonmonogamous long-term relationships, and the ending of long-term partnerships.

Abstract
Despite the clinically proven benefits of the human papillomavirus (HPV) vaccine in preventing cervical and other HPV-associated cancers, vaccination coverage has been suboptimal among adolescents and young adults in the United States (US), particularly among racial and ethnic minority adolescents. Historical legacies, combined with current racial/ethnic disparities in healthcare, may contribute to suboptimal uptake and completion of the HPV vaccine in part through differing levels of trust in doctors and healthcare institutions. The purpose of this narrative review was to characterize trust and its role in decision making about HPV vaccine uptake among US racial and ethnic minorities. We conducted a literature search using the PubMed database, and our search terms yielded 1176 articles. We reviewed 41 full-text articles for eligibility and included 20 articles in this review. These studies used varied measures of trust or mistrust and assessed trust in not only doctors/healthcare providers, but also other sources including pharmaceutical companies, media, and clergy. Our review findings revealed generally high levels of trust in doctors and healthcare providers, but less so in pharmaceutical companies. Mistrust of either healthcare providers, government agencies or pharmaceutical companies was consistently associated with less favorable attitudes and lower vaccine uptake. The downstream effects of mistrust may occur through selected health beliefs regarding the perceived efficacy and safety of the vaccine. Minority groups were more likely to report trust in family members, religious organizations, and media sources compared to their white counterparts. Decision making about vaccine uptake is a multilayered process that involves comparing the perceived benefits of the vaccine against its perceived risks. Understanding how trusted sources can effectively harness the tools of social and traditional media to increase knowledge and awareness may help combat misinformation about the HPV vaccine and improve engagement with diverse communities.

Abstract
Background Although all 11- or 12-year-olds in the US were recommended to receive a 3-dose series of the human papillomavirus (HPV) vaccine within a 12-month period prior to 2016, rates of completion of the HPV vaccine series remained suboptimal. The effects of the Affordable Care Act (ACA), including private insurance coverage with no cost-sharing and health insurance expansions, on HPV vaccine completion are largely unknown. The aim of this study was to examine the associations between the ACA’s 2010 provisions and 2014 insurance expansions with HPV vaccine completion by sex and health insurance type. Methods Using 2009–2015 public and private health insurance claims from Maine, New Hampshire, and Massachusetts, we identified 9-to-26-year-olds who had at least one HPV vaccine dose. We conducted a logistic regression model to examine the associations between the ACA policy changes with HPV vaccine completion (defined as receiving a 3-dose series within 12 months from the date of initiation) as well as interactions by sex and health insurance type. Results Over the study period, among females and males who initiated the HPV vaccine, 27.6 and 28.0%, respectively, completed the series within 12 months. Among females, the 2010 ACA provision was associated with a 4.3 percentage point increases in HPV vaccine completion for the privately-insured (0.043; 95% CI: 0.036–0.061) and a 5.7 percentage point increase for Medicaid enrollees (0.057; 95% CI: 0.032–0.081). The 2014 health insurance expansions were associated with a 9.4 percentage point increase in vaccine completion for females with private insurance (0.094; 95% CI: 0.082–0.107) and a 8.5 percentage point increase for Medicaid enrollees (0.085; 95% CI: 0.068–0.102). Among males, the 2014 ACA reforms were associated with a 5.1 percentage point increase in HPV vaccine completion for the privately-insured (0.051; 95% CI: 0.039–0.063) and a 3.4 percentage point increase for Medicaid enrollees (0.034; 95% CI: 0.017–0.050). In a sensitivity analysis, findings were similar with HPV vaccine completion within 18 months. Conclusions Despite low HPV vaccine completion overall, both sets of ACA provisions were associated with increases in completion among females and males. Our results suggest that expanding Medicaid across the remaining states could increase HPV vaccine completion among publicly-insured youth and prevent HPV-related cancers.

Abstract
Research has demonstrated that the human papillomavirus (HPV) vaccine is a safe and effective way to decrease HPV-related cervical cancers; however, the vaccination rate in the USA is suboptimal. The current study examined racial and ethnic disparities in HPV vaccination among a nationally representative sample, including Native Hawaiian and Pacific Islanders (NHPI). This study also investigated the associations between nativity and vaccination, and sex differences between race/ethnicity and vaccination and nativity and vaccination. A cross-sectional study was conducted with a sample of adults aged 18-26 years drawn from the 2014 NHPI National Health Interview Survey (n = 2590) and the general 2014 National Health Interview Survey (n = 36,697). Log-binomial models were fitted to examine differences in vaccination. There was a statistically significant racial/ethnic difference in HPV vaccination (p = 0.003). More women than men were vaccinated (41.8% vs. 10.1%) (p < 0.001). There was a significant difference in HPV vaccination based on nativity: 27.4% of adults aged 18 to 26 years who were born in the USA and 27.7% born in a US territory received the HPV vaccine compared with 14.3% among those not born in the USA or a US territory (p < 0.001). The association of HPV vaccination with nativity and race/ethnicity differed by sex and showed several nuanced differences. Overall, the prevalence of HPV vaccination was low. The study's findings demonstrate the need for public health strategies to increase vaccination rates among all populations, with the critical need to identify strategies that are effective for men, racial/ethnic minorities, and immigrant women born outside the USA.

Abstract
INTRODUCTION Asian-Americans have been documented to have low human papillomavirus (HPV) vaccine initiation and completion. No research has attempted to examine underlying mechanisms of HPV vaccine uptake disparities among Asian-Americans. Using the P3 (practice, provider, and patient) model, this study aimed to identify practice-, provider-, and patient-level determinants of Asian-Americans' HPV vaccine intention and uptake. METHODS We conducted a systematic review of published literature regarding practice-, provider- and patient-level determinants of vaccine intention (e.g., intention, willingness, or acceptability) and uptake (e.g., initiation or completion). Eligible studies were those presenting empirical/original data, focusing on Asian populations in the U.S., including outcomes related to HPV vaccine intention and uptake, and analyzing data on factors associated with these outcomes separately for Asian groups. RESULTS Twenty-six studies (19 quantitative and 7 qualitative studies) were included in the review. Most commonly studied subgroups were Koreans (n = 9), Chinese (n = 6), and Cambodians (n = 5). Studies showed varied prevalence across subgroups (intention: 23.4%-72%; initiation: 14%-67%; completion: 9%-63%). Only 3 studies included measurements of practice-level determinants (language services, insurance policy). Twelve studies measured provider-level determinants (most commonly documented: HPV vaccine recommendation). All studies measured patient-level determinants (most commonly documented: HPV and HPV vaccine knowledge, perceived safety, perceived susceptibility, and perceived relationship between HPV vaccine and sexual activity). CONCLUSIONS Existing research on determinants of HPV vaccine intention and uptake among Asian-Americans currently lacks measurements of practice-level constructs and perspectives of clinic staff and providers, which are needed to guide system-level interventions and provider training. Data regarding patient-level determinants suggest that interventions for Asian-American populations can focus on providing educational information in culturally-appropriate manners, leveraging familial influences, and attending to access-related or cultural beliefs about HPV vaccine. Interventions should take into account varied vaccine intention and uptake prevalence in different Asian subgroups.

Abstract
INTRODUCTION The nine-valent human papillomavirus (HPV) vaccine could prevent an estimated 92% of the cancers attributable to HPV types targeted by the vaccine. However, uptake of the HPV vaccine among American Indian and Alaska Native (AI/AN) adolescents has been low. AI/ANs also bear a disproportionate burden of cervical and other HPV-associated cancers. Increasing HPV vaccination rates is a national priority, but reviews and national surveys on HPV vaccination factors are lacking for the AI/AN population. The objective of this systematic review is to assess factors associated with HPV vaccination among AI/ANs in the USA. METHODS AND ANALYSIS A systematic review is proposed to synthesise the current literature on HPV vaccination factors in AI/ANs from 1 July 2006 until 30 September 2019. As applicable, controlled vocabulary terms, keywords and special features (eg, limits, explode and focus) will be incorporated into database searches. To maximise the identification of relevant studies, citation indexes and databases that index dissertations, preprints and grey literature are included. Studies will be screened and selected independently in two stages. In stage 1, titles and abstracts will be screened. In stage 2, full-text articles will be screened and selected. A data extraction form and quality assessment tool will be piloted, revised and implemented. If available, measures of frequency and association will be presented. A narrative synthesis of the included studies will also be undertaken and reported. ETHICS AND DISSEMINATION As our review will use publicly available data and publications, an Institutional Review Board review will not be required. We will disseminate the findings from this review through peer-reviewed publication(s) and conference presentation(s). POTENTIAL AMENDMENTS In the event of amendments to the protocol, we will provide the date, rationale, and description of the change for each amendment. PROSPERO REGISTRATION NUMBER CRD42020156865.

Seasonal influenza vaccination in older people: A systematic review and meta-analysis of the determining factors. PLoS One 2020; 15:e0234702. [PMID: 32555628 PMCID: PMC7302695 DOI: 10.1371/journal.pone.0234702] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Accepted: 06/02/2020] [Indexed: 11/30/2022] Open
Abstract
Background/Objectives Despite influenza vaccination programs in various jurisdictions, seasonal influenza vaccine (SIV) uptake remains suboptimal among older people (≥65years old), an important subpopulation for influenza vaccination. We sought to summarize determinants of SIV uptake (any vaccine receipt) and vaccination adherence (receipt of vaccine in two or more seasons in sequence) among older people. Methods We searched for population-based studies conducted in community-dwelling older people (irrespective of their health status) from 2000–2019. Two reviewers independently selected publications for inclusion. One reviewer extracted data from the included studies; a second checked the extracted data for errors. Disagreements were resolved by discussion and consensus, or a third reviewer. We were interested in the determinants of SIV uptake and vaccination adherence. Where appropriate, we pooled adjusted results using the inverse variance, random-effects method and reported the odds ratios (OR) and their 95% confidence intervals (CI). Results Out of 11,570 citations screened, we included 34 cross-sectional studies. The following were associated with increased SIV uptake: being older (OR 1.52, 95%CI 1.38–1.67 [21 studies]), white (1.30, 1.14–1.49 [10 studies]), married (1.23, 1.17–1.28 [9 studies]), non-smoker (1.28, 1.11–1.47 [7 studies]), of a higher social class (1.20, 1.06–1.36 [2 studies]), having a higher education (1.12, 1.04–1.21 [14 studies]), having a higher household income (1.11, 1.05–1.18 [8 studies]), having a chronic illness (1.53, 1.44–1.63 [16 studies]), having poor self-assessed health (1.23, 1.02–1.40 [9 studies]), having a family doctor (2.94, 1.79–4.76 [2 studies]), and having health insurance (1.58, 1.13–2.21 [6 studies]). The influence of these factors varied across geographical regions. Being older (1.26, 1.11–1.44 [2 studies]) was also associated with increased vaccination adherence. Conclusions Several factors may determine SIV uptake and vaccination adherence among older people. More studies are needed to provide a stronger evidence base for planning more effective influenza vaccination programs.

Abstract
BACKGROUND Uptake and completion of the HPV vaccine is suboptimal. This study assessed the feasibility of implementing a one-month Twitter campaign to promote knowledge about the human papillomavirus (HPV) vaccine among low-income women living in public housing. METHODS We recruited a convenience sample (n = 35) of women ages 18-26 years residing in low-come, public housing in Massachusetts. We assessed the feasibility and acceptability of a communication campaign that consisted of daily Twitter messages. Online surveys assessed changes in HPV knowledge, attitudes, and vaccine intentions before and after the campaign. RESULTS Most believed that Twitter was an acceptable educational strategy and remained engaged with the campaign throughout the intervention. We observed no changes in HPV knowledge, perceived benefits of or barriers to vaccination, decision self-efficacy, or vaccine intentions after the campaign, although perceived risk for cervical cancer decreased. CONCLUSIONS Twitter may be a feasible and acceptable method for promoting knowledge about the HPV vaccine, but more research is needed to understand how best to reach low-income women with low levels of vaccine uptake.

Abstract
Objective: This study investigated potential factors associated with HPV vaccine uptake in a diverse population of traditional-age undergraduate students. Participants: One hundred and twenty-nine undergraduate students aged 18-24 attending a small southeastern university completed surveys in January to March of 2013. Methods: Questionnaires included demographic information, basic HPV knowledge, HPV vaccine uptake, and factors influencing uptake decision. Survey results were analyzed with chi-square and t-test analyses. Results: Vaccine uptake was significantly higher in students who reported that health care provider, public health information, parents, and access to vaccine were important factors in their decision to get vaccinated. Female students had a significantly higher vaccine uptake in comparison to males and the HPV knowledge scores differed significantly by race but not gender. Conclusions: It is especially important to consider how public health campaigns and communication with parents and health care providers help promote HPV vaccine uptake in this high-risk group.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccination has been recommended for young adults aged 18-26 years. METHODS Data from the 2016 and 2017 National Health Interview Survey were pooled. RESULTS The prevalence of HPV vaccination initiation (≥1 dose) was 32.54% in 2016 and 37.92% in 2017, and the prevalence of HPV vaccination completion (≥3 doses) was 17.05% in 2016 and 19.38% in 2017 among young adults aged 18-26 years. Being female sex (odds ratio: 4.74) was the leading indicator for receiving the HPV vaccine, followed by receipt of other recommended vaccines (pneumococcal, hepatitis B, and hepatitis A), begin born in the United States, being gay/lesbian, having a greater number of physician visits, being younger, not being married, living in the Northeast, ever having had a pap smear, higher education, being not Hispanic ethnicity, and having more physical activity. Meanwhile, being female sex (odds ratio: 7.23) was the leading indicator for completing the HPV vaccination, followed by receipt of other recommended vaccines (pneumococcal, hepatitis B, and hepatitis A), having a greater number of physician visits, being younger, being born in the United States, being gay/lesbian, living in the Northeast, and current drinking. CONCLUSIONS HPV vaccination coverage remains low among young adults, and HPV vaccine coverage was associated with a number of characteristics.

Gerontol Geriatr Med 2019; 5:2333721419870345. [PMID: 31453267 PMCID: PMC6698992 DOI: 10.1177/2333721419870345] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Revised: 07/25/2019] [Accepted: 07/26/2019] [Indexed: 11/17/2022] Open
Abstract
Background: Despite the availability of a universal influenza
vaccination program in the United States and Canada, seasonal influenza vaccine
(SIV) uptake among the elderly remains suboptimal. Understanding the factors
that determine SIV uptake in this important population subgroup is essential for
designing effective interventions to improve seasonal influenza vaccination
among the elderly. We evaluated the determinants of SIV uptake in the elderly in
the United States and Canada. Methods: We systematically searched
relevant bibliographic databases and websites from 2000 to 2017 for
population-based clinical trials or observational studies conducted in
community-based elderly individuals in the United States or Canada, irrespective
of health status. Two reviewers independently screened the identified citations
for eligibility using a two-stage sifting approach to review the title/abstract
and full-text article. We gathered data on determinants of uptake (any vaccine
receipt) and adherence (receipt of vaccine in more than one season) to seasonal
influenza vaccination. Where possible, we pooled the data using inverse variance
methods to minimize the variance of the weighted average. Results:
Five cross-sectional studies on SIV uptake (none on adherence) from the United
States met our eligibility criteria. Being older (pooled odds ratio [POR] =
1.44, 95% Confidence Interval [CI] = 1.11, 1.86); White (POR = 1.33, 95% CI =
[1.10, 1.64]); and having higher income (POR = 1.06, 95% CI = [1.04, 1.09]); and
health insurance (POR = 1.40, 95% CI = [1.25, 1.55]) were associated with
increased SIV uptake. Conclusion: Older, ethnically White, higher
income elderly individuals with access to health insurance coverage and a
regular health care provider have higher SIV uptake in the United States. There
was limited evidence for other socioeconomic and health-related determinants.
Further studies are needed to provide an evidence base for planning more
effective influenza vaccination programs in the United States.

Variations in reason for intention not to vaccinate across time, region, and by race/ethnicity, NIS-Teen (2008-2016). Vaccine 2018; 37:595-601. [PMID: 30580838 DOI: 10.1016/j.vaccine.2018.12.017] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2018] [Revised: 12/05/2018] [Accepted: 12/10/2018] [Indexed: 11/20/2022]
Abstract
BACKGROUND Human papillomavirus (HPV) vaccination is expected to reduce HPV-related disease and cancer in the US. However, many parents are hesitant to obtain the vaccine for their children. The purpose of this study is to examine how the reasons for refusing the HPV vaccine vary across regions of the US, across time, and by race/ethnicity. METHODS This study used data on 13-17 year old adolescents collected by the National Immunization Survey - Teen (NIS-Teen) annually between 2008 and 2016. We evaluated the frequencies of parents who did not intend to vaccinate their children in the next year among unvaccinated children. Among these non-intenders, we evaluated how reasons for HPV vaccine hesitancy changed across time, by region of the US, and race/ethnicity. RESULTS The proportion of non-intenders among unvaccinated decreased from 72% in 2010 to 58% in 2016. The most frequent reason for vaccine hesitancy was that parents felt HPV vaccination was not necessary (22.4%), followed by lack of provider recommendation (16.2%), and lack of knowledge (15.6%). Lack of provider recommendation increased in frequency as a reason for HPV vaccine hesitancy until 2012, then decreased in frequency through 2016. Cost was one reason that was elevated in all regions compared to the Northeast. Black non-intenders were less likely to report safety, costs, or their children's fear as reasons for not intending to vaccinate their children compared to white non-intenders. Hispanic non-intenders were more likely to report lack of knowledge and that the vaccine is not a school requirement as reasons not to vaccinate their children compared to white non-intenders. CONCLUSIONS National advocacy for improving provider recommendation for HPV vaccination likely contributed to a sharp decline in HPV vaccine hesitancy due to lack of provider recommendation. Results indicate the need for multifaceted interventions to increase HPV vaccination.

Impact of human papillomavirus vaccination on racial/ethnic disparities in vaccine-type human papillomavirus prevalence among 14-26 year old females in the U.S. Vaccine 2018; 36:7682-7688.

Abstract
BACKGROUND Low human papillomavirus (HPV) vaccination rates early after introduction, particularly among low income and minority adolescents, may have resulted in disparities in vaccine-type HPV prevalence (types 6, 11, 16, 18). The purpose of this study was to examine racial/ethnic variations in HPV prevalence, and evaluate how HPV vaccination has affected vaccine-type HPV prevalence across time. METHODS This study was a retrospective analysis of 6 cycles of the National Health and Nutrition Examination Survey (NHANES) data (2003-2014). Results on HPV status from vaginal samples of 14-26 year old females who responded about HPV vaccination were used to determine HPV prevalence. Prevaccine HPV prevalence was compared to post-licensure prevalence. Racial/ethnic comparisons were made across time, and models were developed to examine the role of HPV vaccination in observed variations for vaccine-type HPV prevalence. RESULTS Among 4080 females, 29.7% were black, 25.6% were Mexican American, 8.9% were Hispanic, and 35.8% were white. Compared to prevaccine years (2003-2006), vaccine-type HPV did not decrease until late post-licensure years (2011-2014; 14.2% vs. 5.2%, p < 0.001). Most of the decrease occurred among white females between prevaccine and late post-licensure periods (15.2% vs. 4.1%, p < 0.001). Although a decrease in prevalence was observed among black females during the same periods (16.9% vs. 9.8%, p < 0.05), it was not as large as among white females. Prevalence decreased among Mexican Americans (8.2 vs. 4.0, p > 0.05) during the same periods, but the difference was not significant. Interactions between race and time were significant (p < 0.001), with uneven vaccination between black and white females contributing to the disparities observed. CONCLUSIONS HPV vaccination was low in among black and Mexican American females, which contributed to disparities in HPV prevalence. Increasing vaccination among all adolescents, particularly 11-12 year olds, is important because most children this age will not have been exposed.

Abstract
Human papillomavirus (HPV) is a common sexually transmitted infection which is the cause of several cancers, including cervical cancer, and genital warts. Although cervical cancer can be prevented through screening, this cancer persists in the US. More recently, HPV vaccination has the potential to decrease the burden of HPV-related disease among young HPV-unexposed adolescents. Several initiatives aimed to encourage HPV vaccination have been adopted. Unfortunately, uptake of the HPV vaccine remains modest, despite evidence that vaccine-type HPV prevalence is decreasing as a result of HPV vaccination. Further, geographic disparities in vaccination uptake across different US regions and by race/ethnicity may contribute to continuing disparities in HPV-related cancers. More data are needed to evaluate impact of HPV vaccination on HPV prevalence in smaller geographic areas. Further, more information is needed on the impact of individual vaccination programs and policy on population level vaccination and HPV prevalence.

Abstract
BACKGROUND Overall, foreign-born women are less likely than U.S.-born women to have initiated human papillomavirus (HPV) vaccination. However, foreign-born women are a racially/ethnically diverse population, and race/ethnicity is an independent predictor of HPV vaccination. METHODS Using 2011-2015 National Health Interview Survey data, we used multivariable logistic regression to estimate odds ratios for foreign-born black, Latina, and Asian women compared to foreign-born white women and U.S.-born white women, adjusting for sociodemographic factors. We added socioeconomic factors followed by health care access indicators, which we conceptualized as potential mediators, to each model to assess whether they helped explain observed disparities. RESULTS Foreign-born Asian ([odds ratio=] 0.43; [95% confidence interval:] 0.29-0.65) and Latina (0.46; 0.32-0.68) women had significantly lower adjusted odds of initiating HPV vaccination compared to foreign-born white women. Foreign-born white (0.64; 0.45-0.90), black (0.44; 0.29, 0.67), Latina (0.29; 0.24-0.35), and Asian (0.28; 0.21-0.38) women had significantly lower adjusted odds of HPV vaccination initiation compared to U.S.-born white women. Socioeconomic factors only explained HPV vaccination initiation disparities between foreign-born Latina women and foreign-born and U.S.-born white women. Health care access indicators modestly explained disparities between foreign-born white, black, and Latina women and U.S.-born white women only. CONCLUSIONS We observed pronounced HPV vaccination initiation disparities among foreign-born women in relation to race/ethnicity and between foreign-born women from minoritized racial/ethnic backgrounds and U.S.-born white women. Research on nativity disparities in HPV vaccination should take into account race/ethnicity, and vice versa. Interventions that seek to facilitate HPV vaccination among foreign-born women are needed and should address the unique needs of those from minoritized racial/ethnic backgrounds to promote cancer equity.

Abstract
INTRODUCTION Human papillomavirus (HPV) vaccination, which is recommended for U.S. women and girls aged 11-26 years, effectively prevents cervical cancer. Researchers have identified HPV vaccination disparities among groups of women and girls defined in relation to sexual orientation identity or race/ethnicity. However, no study has used an intersectional approach to ascertain HPV vaccine uptake among sexual orientation identity and racial/ethnic subgroups of U.S. women and girls. METHODS Using 2011-2015 National Survey of Family Growth data, we used multivariable logistic regression to estimate differences in the odds of HPV vaccination initiation (i.e., ≥ one dose) across sexual orientation identity and racial/ethnic subgroups of black and white U.S. women aged 15-24 years (N = 2,413), adjusting for demographic factors. We also assessed whether socioeconomic and health care factors helped explain observed disparities. RESULTS The overall prevalence of HPV vaccination initiation was 47.7%. Compared to white heterosexual women, black lesbians (odds ratio [OR] = 0.16; 95% confidence interval [95% CI]: 0.06-0.46) had the lowest adjusted odds of HPV vaccination initiation, followed by white lesbians (OR = 0.33; 95% CI: 0.13-0.82) and black heterosexual women (OR = 0.63; 0.47-0.85). Including socioeconomic factors in the model only slightly attenuated the HPV vaccination initiation odds ratios for black lesbians (OR = 0.19; 95% CI: 0.06-0.56), white lesbians (OR = 0.37; 95% CI: 0.15-0.90), and black heterosexual women (OR = 0.70; 95% CI: 0.52-0.93) compared to white heterosexual women. Adding health care factors only slightly additionally attenuated the odds ratio comparing black lesbians and white heterosexual women (OR = 0.21; 95% CI: 0.07-0.67). CONCLUSIONS Our findings identified black lesbians as a particularly underserved subgroup and suggest that sexual orientation identity and race/ethnicity may have a compounding effect on HPV vaccination initiation among black and white U.S. women and girls. Evidence-based interventions that are adapted to the specific needs and experiences of black lesbians and other multiply marginalized groups are needed to promote equity in HPV-related outcomes.
