Recent trends in cervical cancer incidence, stage at diagnosis, and mortality according to county-level income in the United States, 2000-2019

Early evidence suggests that declining cervical cancer incidence reversed in low-income regions in the United States in recent years; however, it is unclear whether there are distinct patterns by race/ethnicity and stage at diagnosis and if the increase has translated into rising mortality. Using Surveillance, Epidemiology, and End Results data, we evaluated trends in hysterectomy-corrected cervical cancer incidence rates (2000-2019) and mortality rates (2005-2019) by county-level income and race/ethnicity, with further stratification of incidence by stage at diagnosis. Following a period of decline, hysterectomy-corrected cervical cancer incidence increased 1.0%/year (95% CI = 0.1% to 4.5%) among Non-Hispanic White women in low-income counties. Particularly, a statistically significant 4.4%/year (95% CI = 1.7% to 7.5%) increase in distant-stage cancer occurred in this group. Additionally, recent increases in cervical cancer mortality (1.1%/year [95% CI = -1.4% to 3.7%]) were observed among this group and Non-Hispanic Black women in low-income counties (2.9%/year [95% CI = -2.3% to 18.2%]), but trends were not statistically significant. Among Hispanic women in low-income counties, distant-stage cervical cancer incidence increased 1.5%/year (95% CI = -0.6% to 4.1%), albeit not statistically significant. The increasing incidence of distant-stage cervical cancer and mortality in specific racial/ethnic groups suggests that the recent introduction of higher sensitivity screening tests may not explain increasing trends in low-income counties. Our findings suggest that the observed rise in cervical cancer incidence may reflect disruptions along the screening and treatment continuum. Future research to further comprehend these trends and continued enhancements in prevention are crucial to combat rising cervical cancer incidence and mortality in low-income counties in the United States.

Nativity Disparities in Colorectal Cancer Screening Among Hispanics in the United States

Hispanics in the United States (U.S.) have previously exhibited lower guideline-concordant colorectal cancer (CRC) screening uptake than non-Hispanic (NH) Whites, with disparities accentuated in foreign-born Hispanics, however it is unclear whether nativity-related CRC screening disparities have changed in the last two decades and whether these disparities are attenuated after adjusting for socioeconomic and demographic characteristics. We evaluated CRC screening adherence in foreign- and U.S.-born Hispanics compared to U.S.-born NH Whites. We used 2019 National Health Interview Survey data to compare the prevalence of up-to-date CRC screening per the 2019 U.S. Preventive Services Task Force recommendations among Hispanic nativity subgroups (i.e., foreign- and U.S.-born) and U.S.-born NH Whites using unadjusted and adjusted weighted log-linked binomial regression. Foreign- and U.S.-born Hispanics had a significantly lower unadjusted prevalence of up-to-date screening than U.S.-born NH Whites (47.18% and 64.18% versus 70.70%; p < 0.0001 and p = 0.0109, respectively). After adjusting for socioeconomic and demographic differences, the prevalence of up-to-date screening was lower in foreign-born Hispanics compared to U.S.-born NH Whites [adjusted prevalence ratio 0.80 (95% confidence interval 0.70-0.91)]; however, no statistically significant difference was observed between U.S.-born Hispanics and NH Whites. Our results suggest a low screening uptake in foreign-born Hispanics independent of socioeconomic and demographic differences. Future interventions should target foreign-born Hispanics to address disparities and promote early detection and prevention of CRC regardless of socioeconomic factors.

Factors associated with parental human papillomavirus vaccination intentions among adolescents from socioeconomically advantaged versus deprived households: a nationwide, cross-sectional survey

Background

In the USA, HPV vaccine coverage is substantially lower among adolescents from high-income households compared to their low-income counterparts. We examined and compared the factors associated with parental HPV vaccination intentions between socioeconomically divergent groups.

Methods

Data from unvaccinated and not fully HPV-vaccinated adolescents from the 2017-2021 National Immunization Survey (NIS)-Teen were analyzed. Socioeconomically advantaged vs. deprived groups were identified based on dichotomized income (material capital) and education (social capital). Parental intent to initiate and complete the HPV vaccine series was compared using bivariable analysis and the factors associated with lacking intent were identified.

Findings

The 2017-2021 NIS-Teen included a total of 212,643 participants; the final analytical sample consisted of 105,958 adolescents (an estimated 10.3 million adolescents) who were unvaccinated or not fully vaccinated. In the advantaged group, 64.7% of parents of unvaccinated adolescents (equating to 2.4 million US adolescents) had no intention to initiate the HPV vaccine compared to 40.9% of parents in the deprived group (equating to 0.2 million adolescents) (P < 0.0001; S > 13.29). The most frequent reason for lacking intent in the advantaged group was 'safety concerns' (25.5%). In the deprived group, 'lack of knowledge', 'not recommended', and 'not needed' were common reasons (nearly 15% each). Lack of intent to complete the HPV vaccine series was higher in the advantaged group (43.9%; 1.1 million adolescents) compared to the deprived group (25.2%; 0.08 million adolescents) (P < 0.0001; S > 13.29). More than half in the advantaged group (58.4%) and over a third (37.1%) in the deprived group cited 'already up to date' as the main reason for not completing the HPV vaccine series.

Interpretation

Lack of intent to initiate and complete the HPV vaccination series, particularly among socioeconomically advantaged parents is a significant barrier to achieving the national goal in the USA.

Self-Sampling for Human Papillomavirus Testing: Acceptability in a U.S. Safety Net Health System

INTRODUCTION

Self-sampling for human papillomavirus testing is increasingly recognized as a strategy to expand cervical cancer screening access and utilization. Acceptability is a key determinant of uptake. This study assesses the acceptability of and experiences with mailed self-sampling kits for human papillomavirus testing among underscreened patients in a safety net health system.

METHODS

A nested telephone survey was administered between 2021 and 2023 to a sample (n=272) of the 2,268 participants enrolled in the Prospective Evaluation of Self-Testing to Increase Screening trial. Trial participants include patients of a safety net health system aged 30-65 years who were not up to date on screening. Participants were asked about barriers to provider-performed screening. Kit users and nonusers were asked about their experiences.

RESULTS

Prevalent barriers to provider-performed screening included perceived discomfort of pelvic examination (69.4%), being uncomfortable with male providers (65.4%), and embarrassment (57.0%). Among participants who reported using the mailed kit (n=164), most reported good experiences (84.8%). Most reported self-sampling as more/equally convenient (89.0%), less/equally embarrassing (99.4%), and less/equally stressful (95.7%) than provider-performed screening. Among kit nonusers (n=43), reasons for not using the kit included forgetting about it (76.7%), preferring provider-performed screening (76.7%), and fearing cancer (67.4%).

CONCLUSIONS

Prospective Evaluation of Self-Testing to Increase Screening trial participants generally had a positive experience with self-sampling for human papillomavirus testing. Increased comfort and reduced embarrassment/anxiety with self-sampling are relevant attributes because these were the most prevalent reported barriers to provider-performed screening. High acceptability suggests potentially high uptake when self-sampling for human papillomavirus testing receives regulatory approval and is available in safety net health systems.

Health equity in action: using community-engaged research to update an intervention promoting a healthy home food environment to Black/African American families

PURPOSE

Describe the method for conducting community-engaged research to identify needed changes for an existing evidence-based intervention, and prepare it for implementation in a community setting within the Dan L Duncan Comprehensive Cancer Center catchment area in an effort to achieve more equitable outcomes in diet-related disease risk factors.

METHODS

The intervention, Family Eats, was developed over 10 years ago. It works directly with parents of Black/African American 9-12 year old children to create a healthy home food environment to support prevention of obesity and related cancers. Data collection with community stakeholders occurred through a series of  Community Advisory Board (CAB) meetings guided by the Delphi Technique, an iterative approach for gaining group consensus on a topic.

RESULTS

Key information on needed changes and potential implementation strategies were identified. Perceived level of engagement among CAB members was high overall and in terms of both quantity and quality.

CONCLUSION

The Delphi Technique shows promise as a method for conducting community-engaged research that promotes engagement and identifies key information needed to adapt and implement an existing intervention in a community setting.

Determinants of Low-Income Women's Participation in Self-Collected Samples for Cervical Cancer Detection: Application of the Theory of Planned Behavior

BACKGROUND

Low-income women (LIW) are underrepresented in physician-provided cervical cancer screening. Providing women with an option for Human Papillomavirus (HPV) self-sampling would increase cervical cancer screening. However, little is known about LIW's attitude towards self-sampling for cervical cancer. We determined the associations between the Theory of Planned Behavior (TPB) constructs and LIW intention for participation in the HPV self-sampling.

METHODS

A 44-item survey was administered among women receiving food from a food pantry in central Texas. Independent variables included TPB constructs (i.e., attitudes, subjective norms, and perceived control). The outcome variables were intentions and preference for self-sampling. Both variables were measured on a 5-point scale. Hierarchical linear regression models were used to analyze the data.

RESULTS

A sample of 241 participants (age 50.13 ± 9.60 years) comprising non-Hispanic White (40%), Black/African American (27%), and Hispanic (30%) participated in the study. The participants were current with a pap test (54.8%) and preferred self-sampling (42%). The participant's attitudes and subjective norms were significantly associated with their intention for self-sampling, accounting for 38.7% of the variance (p < .001). Women who were overdue for pap testing versus current with pap testing had increased odds of preferring self-sampling (OR = 1.72, 95% CI: 1.27, 6.04).

CONCLUSIONS

The key predictors for LIW's intention for self-sampling included attitudes and subjective norms. Future research should use the TPB as a framework to examine whether intention predicts self-sampling behavior among LIW.

Behavioral weight-loss interventions for patients with NAFLD: A systematic scoping review

BACKGROUND

Clinically significant weight loss-which requires sustained dietary and physical activity changes-is central to treating NAFLD. Although behavioral interventions have demonstrated effectiveness in promoting weight loss among primary prevention populations, the data are limited among patients with NAFLD who need weight loss for treatment. We undertook this scoping review to map the existing data on the characteristics, weight-loss outcomes, and determinants of success of interventions evaluated among patients with NAFLD.

METHODS

We searched Medline, EMBASE, Cochrane, PsycINFO, and Web of Science from inception to January 1, 2023 to identify publications reporting weight loss among adults with NAFLD in behavioral weight-loss interventions. We summarized interventions and classified them as successful if there was an average weight loss of ≥ 5% from baseline across enrolled participants or achieved by ≥ 50% of enrolled participants.

RESULTS

We included 28 studies: 10 randomized control trials, ten quasi-experimental, and 8 observational studies. Intervention delivery, duration, and counseling frequency varied; 12 were successful. Retention was highest among telephone interventions and lowest among "real-world" face-to-face interventions. Patients who were women, younger, and/or had multiple metabolic conditions were most likely to dropout. Successful interventions had biweekly counseling, specific physical activity, and calorie targets, behavioral theory grounding, and promoted goal-setting, self-monitoring, and problem-solving.

CONCLUSION

There are limited data on behavioral weight-loss interventions in NAFLD. Research is needed to develop effective interventions generalizable to diverse patient populations and that maximize adherence, particularly among patients who are diabetic, women, and younger.

Cervical cancer screening among English- and Spanish-speaking Hispanic women in an urban safety net health system, 2015-2020

BACKGROUND

The Hispanic population is heterogeneous with differences in health behaviors across subgroups by nativity and preferred language. We evaluated cervical cancer screening adherence among English- and Spanish-speaking Hispanic patients receiving care at a safety net health system.

METHODS

Electronic health records were used to identify 46,094 women aged 30-65. Up to date (UTD) screening was defined based on date of last Pap test, human papillomavirus (HPV) test, or Pap/HPV co-test.

RESULTS

Overall, 81.5% of 31,297 Hispanic women were UTD. English-speaking Hispanic women had a lower prevalence of being UTD when compared to Spanish-speaking Hispanic women (aPR: 0.94, 95% CI: 0.93 - 0.96). Further, those with indigent healthcare plans had a higher prevalence of being UTD when compared to those with private insurance (aPR: 1.10, 95% CI: 1.09 - 1.12), while all other health insurance plans were associated with lower UTD screening when compared to private insurance.

CONCLUSIONS

These findings suggest screening differences within the Hispanic population, highlighting the need for disaggregated research assessing heterogeneity within racial/ethnic groups, specifically among Hispanic populations.

Racial/Ethnic Disparities in Cervical Cancer Stage at Diagnosis: Mediating Effects of Neighborhood-level Socioeconomic Deprivation

BACKGROUND

Mortality from cervical cancer has declined steadily in the United States over the past several decades due to widespread screening for precancerous and early-stage cervical cancer (ECC), which are significantly easier to treat compared with late-stage cervical cancer (LCC). Unequal screening access continues to cause significant racial/ethnic disparities in cervical cancer diagnosis stage. This study examined the underlying role of neighborhood-level socioeconomic disadvantage as a potential mediator of the association between race/ethnicity and cervical cancer diagnosis stage.

METHODS

We analyzed Texas Cancer Registry data for cervical cancer cases diagnosed among women ages 18 or older from 2010 to 2018. We performed causal mediation analyses of the association between race/ethnicity and cervical cancer stage at diagnosis mediated by neighborhood-level socioeconomic disadvantage.

RESULTS

Of the 9,192 women with cervical cancer, 4,720 (51.3%) had LCC at diagnosis. Compared with non-Hispanic white (NHW) women (106.13, standard deviation (SD) = 13.32), non-Hispanic Black (NHB; 111.46, SD = 9.55) and Hispanic (112.32, SD = 9.42) women had higher area deprivation index (ADI) and had greater odds of LCC diagnosis [total effects: adjusted odds ratios (AOR) = 1.29 (95% CI, 1.11-1.46) and AOR 1.14 (95% CI, 1.03-1.25), respectively]. Approximately 34.7% and 71.6% of the disparity in LCC diagnosis were attributable to higher neighborhood socioeconomic disadvantage among NHB and Hispanic women, respectively.

CONCLUSIONS

LCC disparity varied by race/ethnicity and was partly attributable to neighborhood disadvantage. The disparity among Hispanic women due to neighborhood deprivation was twice as high among NHB women.

IMPACT

Findings may be used to develop targeted race- and place-specific interventions to improve cancer care equity.

Perceived barriers to cervical cancer screening and motivators for at-home human papillomavirus self-sampling during the COVID-19 pandemic: Results from a telephone survey

Background: Home-based self-sampling for human papillomavirus (HPV) testing may be an alternative for women not attending clinic-based cervical cancer screening.

Methods: We assessed barriers to care and motivators to use at-home HPV self-sampling kits during the COVID-19 pandemic as part of a randomized controlled trial evaluating kit effectiveness. Participants were women aged 30-65 and under-screened for cervical cancer in a safety-net healthcare system. We conducted telephone surveys in English/Spanish among a subgroup of trial participants, assessed differences between groups, and determined statistical significance at p<0.05.

Results: Over half of 233 survey participants reported that clinic-based screening (Pap) is uncomfortable (67.8%), embarrassing (52.4%), and discomfort seeing male providers (63.1%). The last two factors were significantly more prevalent among Spanish versus English speakers (66.4% vs. 30% (p=0.000) and 69.9 vs. 52.2% (p=0.006), respectively). Most women who completed the kit found Pap more embarrassing (69.3%), stressful (55.6%), and less convenient (55.6%) than the kit. The first factor was more prevalent among Spanish versus English speakers (79.6% vs. 53.38%, p=0.001) and among patients with elementary education or below.

Conclusions: The COVID-19 pandemic influenced most (59.5%) to participate in the trial due to fear of COVID, difficulty making appointments, and ease of using kits. HPV self-sampling kits may reduce barriers among under-screened women in a safety-net system.

Funding: This study is supported by a grant from the National Institute for Minority Health and Health Disparities (NIMHD, R01MD013715, PI: JR Montealegre).

Perceived Barriers and Use of Evidence-Based Practices for Adolescent HPV Vaccination among East Texas Providers

Adolescents living in rural areas are less likely to be up to date on the human papillomavirus (HPV) vaccine, which can prevent cervical cancer. We administered a telephone survey to 27 clinics in rural East Texas to assess perceived barriers to HPV vaccination and current use of evidence-based interventions to promote HPV vaccination. Perceived barriers were assessed using a 5-point Likert scale and clinical implementation of evidence-based practices was determined. Findings are reported using descriptive statistics. The most commonly reported barriers were missed vaccination opportunities due to the pandemic (66.7%), followed by vaccine hesitancy due to the pandemic (44.4%) and due to the HPV vaccine specifically (33.3%). Fewer than a third of clinics reported using the evidence-based strategies of use of a “refusal to vaccinate” form (29.6%), having an identified HPV vaccine champion (29.6%), and recommending the HPV vaccine at age 9 (22.2%). While many clinics surveyed currently implement evidence-based practices to promote HPV vaccination, there is a need and desire for additional HPV vaccination interventions in East Texas clinics.

Trends in Up-To-Date Colorectal Cancer Screening Among U.S. Adults Aged 50-75 Years and Variations by Race/Ethnicity and U.S. Census Bureau Divisions

Introduction

Mortality rates from colorectal cancer have declined over the past decades owing to population-based life-saving screening interventions. However, screening inequalities continue among racial and ethnic minorities despite having a higher disease burden. In this study, we assessed the patterns of up-to-date colorectal cancer screening rates among racial/ethnic groups across the U.S. Census Bureau Divisions.

Methods

This population-based cross-sectional study used weighted data from 4 cycles of the Behavioral Risk Factors Surveillance System (2014, 2016, 2018, and 2020) of adults aged 50‒75 years without a previous diagnosis of colorectal cancer. The primary outcome was guideline-recommended up-to-date colorectal cancer screening. We used logistic regression models to examine temporal trends in up-to-date colorectal cancer screening from 2014 to 2020. In addition, we conducted detailed descriptive statistics of up-to-date screening rates, comparing trends in 2020 with those in 2014 overall by race/ethnicity and U.S. census divisions.

Results

The overall proportion of individuals with up-to-date colorectal cancer screening increased from 66.5% in 2014 to 72.5% in 2020 (p<0.001). For racial/ethnic subgroups, from 2014 to 2020, screening rates increased significantly among non-Hispanic Whites (68.5%‒74.5%, p<0.001), non-Hispanic Blacks (68.0%‒74.6%, p<0.001), and Hispanics (51.5%‒62.8%, p<0.001). However, increases were not observed in all U.S. Census Bureau Divisions.

Conclusions

Although colorectal cancer screening rates improved over time, they fall short of the 80% target. Substantial racial/ethnic and geographic disparities remain. Future studies investigating the factors influencing these disparities are needed.

Sexual Behaviors and Human Papillomavirus Vaccination in a Heterosexually Active Adult Population at Increased Risk for HIV Infection

Human papillomavirus (HPV) is the most common sexually acquired infection in the US. Vaccination is effective against infection with high-risk HPV strains, yet HPV vaccine coverage is lower in the US than the national target. This study aimed to determine the relationship between sexual behaviors and HPV vaccination in a heterosexually active population at increased risk for HIV infection. Data from 380 participants aged 18-45 years obtained from the National HIV Behavioral Surveillance system increased risk heterosexuals cycle 5 (2019) in Houston, Texas, was analyzed. RDS-Analyst was used to generate population-based descriptive statistics. Modified Poisson regression models clustered on recruitment chain were conducted in SAS 9.4 to assess the relationship between sexual behaviors and HPV vaccination. Only 11.5% of participants had received at least one dose of the HPV vaccine. Regarding behaviors within the past 12 months, 44.8% reported having condomless casual sex, 51.3% reported having concurrent sexual partnerships while in their most recent relationship, 14.5% reported exchanging sex, and participants had an average of 4-5 sex partners. Further, those who exchanged sex had a significantly lower prevalence of HPV vaccine uptake when compared to those who did not exchange sex (adjusted prevalence ratio 0.23; confidence interval 0.10-0.52), while all other measures of sexual behavior were not significantly associated with HPV vaccination. More research is needed to understand the relationship between exchange sex and low prevalence of vaccination, specifically in women who bear the highest burden of poor HPV-related morbidity and mortality.

Trends and Racial/Ethnic Differences in Predictors of Cervical Cancer Screening among US Women Ages 30-64 Years

BACKGROUND

Cervical cancer screening (CCS) participation has decreased in the United States over the last several decades, contributing to cervical cancer's sustained incidence and mortality. This study examined recent trends and racial/ethnic differences in predictors of CCS uptake among US women.

METHODS

We analyzed combined data from the 2016 to 2020 Behavioral Risk Factor Surveillance System (BRFSS) and included 235,713 women ages 30 to 64 years without a hysterectomy. We used simple linear regression to assess trends over time and multivariable logistic regression models to evaluate racial/ethnic differences in predictors of up-to-date CCS.

RESULTS

We found little change in CCS over the 5-year interval and screening rates disparities among racial minority women. The overall population showed stable CCS completion rates from 2016 to 2018 (84.2% vs. 84.6%), and then a small dip from 2018 to 2020 (from 84.6% to 83.3%). Despite a slight decline in 2020, HPV-based testing increased significantly among all subgroups and overall, from 2016 to 2020 (from 43.4% to 52.7%). Multivariable regression models showed racial/ethnic differences in predictors of CCS. Across all racial/ethnic subgroups, older women were less likely to receive timely screening. Women who had routine check-ups had higher odds of being up to date. However, the link between CCS and socioeconomic status varied.

CONCLUSIONS

Age and racial/ethnic disparities persist in CCS, and predictors of screening vary. Notwithstanding, routine health examinations was positively associated with screening regardless of race/ethnicity.

IMPACT

Our analyses suggest that leveraging primary care to optimize CCS uptake may reduce gaps in screening.

Human papillomavirus vaccinations at recommended ages: How a middle school-based educational and vaccination program increased uptake in the Rio Grande Valley

Human papillomavirus (HPV) vaccination is recommended for U.S. adolescents at ages 11-12 requiring two or three doses depending on if the vaccine series started before age 15. The objective was to compare HPV vaccination rates among medically underserved, economically disadvantaged, students in rural middle school districts (Rio Grande Valley [RGV], Texas) by age of initiation (≤ age 11 years vs. age 12 years and older). This quasi-experimental study included 1,766 students (884 females; 882 males) who received at least one HPV vaccine dose through our school-based vaccination program between 08/2016-06/2022. Summary statistics were stratified by age at initiation and gender. The overall HPV up-to-date (UTD) rate was 59.7% (95% Confidence Interval: 57.4-62.0%). The median age at HPV UTD (range) was 12 years (9-19) and median interval between HPV vaccine doses (range) was 316 days (150-2,855). Most students received the HPV vaccine bundled with other vaccinations (72.4%, 1,279/1,766). There was a higher HPV UTD rate among students who initiated the HPV vaccine on or before age 11 than those who initiated on or after age 12 (73.6% versus 45.1%, respectively). The median age of HPV UTD was age 12 for those initiating on or before 11 years versus age 13 for those initiating on or after 12 years of age. Initiating the HPV vaccine at age ≤11 years increased completion of the HPV vaccine series. Improving HPV vaccine coverage and introduction of pan-gender vaccination programs will significantly decrease HPV-related diseases in the RGV.

Perceived barriers to cervical cancer screening and motivators for at-home human papillomavirus self-sampling during the COVID-19 pandemic: Results from a telephone survey

Home-based self-sample human papillomavirus (HPV) testing may be an alternative for women who do not attend clinic-based cervical cancer screening. We assessed barriers to care and motivators to use at-home HPV self-sampling kits during the COVID-19 pandemic as part of a randomized controlled trial evaluating kit effectiveness. Participants were women, aged 30-65 years and underscreened for cervical cancer in a safety-net healthcare system. We conducted telephone surveys in English/Spanish among a subgroup of trial participants, assessed differences between groups and determined statistical significance at p<0.05. Over half of 233 survey participants reported clinic-based screening (Pap) is uncomfortable (67.8%), embarrassing (52.4%), and discomfort seeing male providers (63.1%). The latter two factors were significantly more prevalent among Spanish versus English speakers (66.4% vs 30% and 69.9 vs 52.2%, respectively, p<0.01). Most women who completed the kit found Pap more embarrassing (69.3%), stressful (55.6%) and less convenient (55.6%) than the kit. The first factor was more prevalent among Spanish versus English speakers (79.6% vs 53.38%, p<0.05). The COVID-19 pandemic influenced most (59.5%) to participate in the trial due to fear of COVID, difficulty making appointments and ease of using kits. HPV self-sampling kits may reduce barriers among underscreened women in a safety-net system.

Human Papillomavirus Vaccinations During the COVID-19 Pandemic in Middle Schools in the Rio Grande Valley of Texas

This quasi-experimental study (a community-based, physician-led human papillomavirus [HPV] education campaign and school-based vaccination program) followed 6481 students at eight Pharr-San Juan-Alamo Independent School District (Rio Grande Valley, Texas) middle schools between August 2016 and March 2021. We describe the successes and challenges experienced during the COVID-19 pandemic. HPV vaccine initiation and completion rates increased 1.29-fold and 1.47-fold, respectively, between June 2019 and March 2021. Between March 2020 and March 2021, 268 HPV vaccine doses were provided through 24 school-based interventions. Our program continued successes seen in increasing HPV vaccination rates and reducing possible HPV-associated cancers.

The Texas collaborative center for hepatocellular cancer: Reducing liver cancer mortality in Texas through coordination, collaboration and advocacy

Texas has the highest age-adjusted incidence rate of hepatocellular carcinoma (HCC) in the United States. To address cancer prevention and early detection through research, Cancer Prevention and Research Institute of Texas (CPRIT) has funded the Texas Collaborative Center for Hepatocellular Cancer (TeCH) to facilitate liver cancer research, education and advocacy activities. This paper describes the organizational structure, program measures, the actions completed and future plans of TeCH. This center is comprised of several cores and committees including the Administrative Core, Steering Committee, Data and Biospecimen Core, Scientific Committee, Clinical Network Committee, and the Community Outreach Committee. Each core and committee provide its own level of connectivity and necessary research support. We have developed and published a TeCH Framework, a conceptual model designed for improving primary and secondary prevention of HCC. TeCH and its committees facilitate connections and collaborations among HCC researchers and clinicians, healthcare leaders, biotechnology companies and the public to reduce liver cancer mortality in Texas by 2030.

Awareness of human papillomavirus and reported human papillomavirus vaccine uptake in a high-risk population

Introduction

Disparities in human papillomavirus (HPV) awareness and HPV vaccine uptake are likely exacerbated among racial/ethnic minority populations living in low-income areas. This study aims to determine the prevalence and correlates of HPV awareness and HPV vaccine uptake in an urban, low-income, racial/ethnic minority population.

Methods

Secondary data analyses were performed in 2021 using 380 participants aged 18-45 years from the 2019 National HIV Behavioral Surveillance for high-risk heterosexuals, which monitors HIV risk behaviors among individuals living in high-poverty, high HIV prevalence neighborhoods. Prevalence estimates and modified Poisson regression models were used to assess the relationship between HPV awareness and HPV vaccine uptake, and sociodemographic characteristics.

Results

Only 53% of participants had heard of HPV and 11.5% had received at least one dose of the HPV vaccine. Those who were female, non-Hispanic White or other, had public health insurance, lived above the federal poverty level, had experienced homelessness and incarceration, and had usual source of healthcare showed higher awareness of HPV while those who were younger, female, non-Hispanic White or other, recently incarcerated, had a usual source of healthcare, and had a healthcare encounter in the past year showed higher prevalence of HPV vaccine uptake.

Conclusions

Prevalence of HPV vaccination in this high-risk population was low and there was a lack of preventive care utilization. Further research is needed on how to effectively target these populations to not only increase vaccine uptake, but to mitigate barriers that contribute to low awareness and suboptimal vaccination uptake in high-risk heterosexual populations.

A Conceptual Model for Implementation and Evaluation of Interventions Across the Hepatocellular Carcinoma Care Continuum

Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related death worldwide and one of the few cancers with a rising mortality in the United States. There are opportunities for intervention along the cancer care continuum (CCC), which includes risk assessment, primary prevention, detection (ie, screening initiation and follow-up of screening results), diagnosis, and treatment.¹ Each step is prone to failures that are influenced by factors at multiple socioecological levels (ie, patient, provider, health delivery system, community, and policy levels).² We recently described a conceptual model of the steps and interfaces along the CCC that are required for effective implementation of HCC screening in clinical practice.³ Herein, we present a conceptual model for the implementation and evaluation of interventions at each of the socioecological levels using implementation strategies that promote optimal delivery and uptake. We focus on early steps in the CCC, including risk assessment, primary prevention, and early detection (ie, secondary prevention), because these have the greatest potential to reduce HCC mortality.

Adolescent electronic cigarette counselling: knowledge, attitudes and perceived barriers among clinical staff in a primary care setting

OBJECTIVE

To assess knowledge, attitudes, and perceived barriers (KAP) regarding e-cigarette use counselling among adolescent healthcare clinical staff in an urban system, and to compare results between providers and rooming staff.

METHODS

Primary care clinical staff (n = 169) completed an anonymous survey. Descriptive statistics and Chi-square tests were used to summarize data and compare KAP between medical providers and rooming staff.

RESULTS

Staff wanted to learn more about e-cigarettes (87.6%). The most common knowledge deficits were how to use the 5As + 5Rs model for tobacco cessation counselling (66.7%) and the chemical content of e-liquids (55.4%), with no differences across groups. Overall, 58% of providers expressed confidence in their ability to talk with adolescent patients about e-cigarette use. The most common barriers to counselling were low knowledge about e-cigarettes (74.0%) and how to refer adolescent patients for cessation support (43.8%).

CONCLUSIONS

Provider and rooming staff expressed similar educational needs surrounding e-cigarettes, counselling, and treatment for adolescent patients. Clinical staff expressed confidence in their ability to affect change. There were no differences in the identified knowledge gaps or barriers to care between rooming staff and providers, suggesting that the same educational format can be used to target both groups.

Trends in Human Papillomavirus Vaccine Safety Concerns and Adverse Event Reporting in the United States

IMPORTANCE

In the US, safety concern has been identified as a primary barrier to initiating the human papillomavirus (HPV) vaccine. It is unclear if the public's sentiment concerning HPV vaccine safety aligns with postmarketing vaccine safety surveillance data.

OBJECTIVE

To perform a parallel assessment of trends in HPV vaccine safety concerns and HPV vaccine adverse event (AE) reporting.

DESIGN, SETTING, AND PARTICIPANTS

This study was a cross-sectional analysis of the National Immunization Survey (NIS) and Vaccine Adverse Event Reporting System (VAERS). Participants in the NIS were adolescents aged 13 to 17 years. AEs were reported to VAERS by patients, health care clinicians, or other sources. Statistical analysis was performed from October 2020 to May 2021.

MAIN OUTCOMES AND MEASURES

Secular trends in HPV vaccine safety concerns and spontaneous AE reporting for HPV vaccination from 2015 to 2018.

RESULTS

Caregivers of 39 364 unvaccinated adolescents with a mean (SD) age of 15.57 (0.08) years (26 996 White adolescents [62.9%], 22 707 male adolescents [56.1%], 11 392 privately insured [62.6%], and 32 674 above the poverty level [79.3%]) reported their reasons for not initiating the HPV vaccine series in the 2015-2018 NIS. Citing safety concerns as the primary reason for not initiating the HPV vaccine series increased from 13.0% (95% CI, 12.1%-14.0%) in 2015 to 23.4% (95% CI, 21.8%-25.0%) in 2018 (P for trend < .001), equating to a change from 170 046 to 259 157 US adolescents not initiating the vaccine because of safety concerns. The proportion of parents citing safety concerns as the main reason for HPV vaccine hesitancy increased in 30 states. The largest increases (more than 200%) were observed in California, Hawaii, South Dakota, and Mississippi. During 2015 to 2018, 16 621 AE reports following HPV vaccination were reported to VAERS. The AE reporting rate per 100 000 doses distributed decreased from 44.7 in 2015 to 29.4 in 2018 (P for trend < .001). The serious AE reporting rate, including those leading to hospitalizations, disability, life-threatening condition, or death did not change.

CONCLUSIONS AND RELEVANCE

In this descriptive cross-sectional study, a rise in citing safety concerns was observed among parents with HPV vaccine hesitancy, contrary to the nonserious and serious AE reporting trends. These findings suggest an urgent need to combat the rising sentiment of safety concerns among caregivers to increase HPV vaccine confidence.

Incomplete Records as a Leading Cause of Missed Opportunity for Human Papillomavirus Vaccine Initiation in a Safety Net Health System

OBJECTIVE

The goal of this study was to categorize reasons behind missed opportunities for human papillomavirus (HPV) vaccine initiation in an under-resourced population and to identify associated patient and clinic characteristics.

METHODS

Manual chart review was performed for patients aged 11 to 18 years who visited a primary care clinic in a health system in Texas, USA between 06/01/18 and 08/31/18 and were due for an initial HPV vaccine dose but did not receive it. Reasons for HPV vaccine noninitiation were categorized as follows: incomplete immunization record, no documentation of discussion (no documentation that the HPV vaccine was offered or ordered), refusal, staff/provider error, and medical. Multinomial logistic regression was used to examine factors associated with each category.

RESULTS

Of 4467 adolescents seen in the study period, 575 (12.9%) were due for the first dose of HPV vaccine but did not receive it. The most common reason for noninitiation was incomplete immunization record (37%), followed by no documentation of discussion (24%), refusal (20%), staff/provider error (15%), and medical (4%). The highest odds of incomplete immunization were among older adolescents. The highest odds of no documentation of discussion were during sick visits. The highest odds of staff/provider error were among patients with commercial insurance. The lowest odds of refusal were in patients with county/indigent insurance.

CONCLUSIONS

The most common reason for missed opportunity visits for HPV vaccine initiation was lack of adequate immunization records. Our study highlights the importance of immunization record access and bidirectional reporting as important targets for future interventions.

Abstract 53: Promoting WHO's Cervical Cancer Elimination Goals ‘90-70-90' by Developing, Implementing, and Evaluating the ECHO Latin America (ECHO ELA) Program

Purpose: Cervical cancer is one of the leading causes of cancer deaths among women in some countries in the Region of the Americas.1 Cervical cancer is preventable through HPV vaccination, screening and treatment of precancerous lesions, and can be effectively treated if diagnosed early.2

Methods: Under the framework of the Global Strategy to Accelerate the Elimination of Cervical Cancer as a Public Health Problem, the US National Cancer Institute (NCI), the University of Texas MD Anderson Cancer Center (MD Anderson) and the Pan American Health Organization/World Health Organization (PAHO/WHO) partnered to develop ECHO Latin America (ECHO ELA). ECHO ELA is modeled on Project ECHO® (Extension of Community Healthcare Outcomes) a hub-and-spoke knowledge-sharing approach where expert teams lead virtual didactic lectures and case discussions, amplifying the capacity for participants to deliver best practice programs to their regions. ECHO ELA consists of monthly, Spanish-language telementoring conferences about cervical cancer prevention and control. The program targets Ministries of Health, Immunization Program Managers and key cervical cancer stakeholders in Latin American (LA) countries. Its primary goal is to assist countries in reaching their WHO cervical cancer elimination goals “90-70-90:” vaccinating 90 percent of girls against HPV by the age of 15, screening 70 percent of women for cervical cancer at ages 35 and 45, and treating 90 percent of women diagnosed with pre-invasive cervical lesions or cervical cancer.

Results: To date, 222 participants from 21 countries have registered. Seven sessions have been held averaging 93 participants per session. 85 participants completed the baseline survey addressing priorities, capacity, and desired outcomes. Baseline, mid-year evaluation results, within the COVID-19 context, and learned lessons will be presented.

Conclusion: ECHO ELA is potentially an effective tool to convene participants from multiple countries to enhance collaboration and support countries' progress towards the elimination of cervical cancer in the Americas.

Human papillomavirus awareness among foreign- and US-born Hispanics, United States, 2017-2018

INTRODUCTION

Human papillomavirus (HPV) and HPV vaccine knowledge and awareness are known to be lower among Hispanics compared to non-Hispanic whites. However, Hispanics in the US are a non-homogenous population, with significant differences by nativity, particularly between the US-and foreign-born individuals. We examined HPV and HPV vaccine awareness among foreign-born Hispanics, US-born Hispanics, and US-born non-Hispanic whites.

METHODS

We analyzed data from the Health Information National Trends Survey (HINTS) 5, cycles 1 (2017) and 2 (2018), the most recent HINTS datasets including nativity information. We used descriptive statistics and multivariable regression to compare awareness of HPV and the HPV vaccine among ethnicity/nativity subgroups.

RESULTS

Over 50% of foreign-born Hispanics had not heard of HPV, compared to 32% of US-born Hispanics (P < 0.01) and 33% of non-Hispanic whites (p < 0.01). Lack of HPV vaccine awareness among foreign-born Hispanics was not significantly different from US-born Hispanics (52% vs. 44%, p = 0.12), but was significantly lower compared to non-Hispanic whites (52% vs. 32%, p < 0.01). In multivariable analyses, non-Hispanic whites had over twice the odds of having heard of HPV than foreign-born Hispanics (p < 0.05), while US-born Hispanics had 75% higher odds (p < 0.05). Regarding HPV awareness, non-Hispanic whites had 95% higher odds of having heard of the HPV vaccine than foreign-born Hispanics (p < 0.05), while differences between US and foreign-born Hispanics were not significant.

CONCLUSION

There are significant nativity-related differences in HPV and HPV vaccine awareness and knowledge among US-born Hispanics. Over 50% of foreign-born Hispanic adults are unaware of HPV and the HPV vaccine.

Predictors of timely diagnostic follow-up after an abnormal Pap test among Hispanic women seeking care in El Paso, Texas

BACKGROUND

Diagnostic follow-up of women with an abnormal Pap test is necessary to resolve the risk developing cervical cancer. The purpose of this study is to describe patient characteristics associated with timely receipt of a diagnostic colposcopy after an abnormal Pap test among Hispanic women in El Paso, a Texas-Mexico border city.

METHODS

We conducted a retrospective chart review of Hispanic patients seen at an academic colposcopy clinic following an abnormal Pap test. An optimal diagnostic interval to colposcopy was based on a National Breast and Cervical Cancer Early Detection Program (NBCCEDP) quality indicator and was defined as receipt of colposcopy within 90 days or less from the date of an abnormal Pap test. Risk ratios (RR) were calculated by building a generalized linear model fit using a Poisson distribution, log link, and robust variance.

RESULTS

Overall, 177 of the 270 women (65.6%) received follow-up within an optimal diagnostic interval. After adjusting for other variables in the model, women who were 30 years of age or older were 32% more likely to have an optimal interval than younger women (adjusted RR = 1.32, P < 0.01). High school graduates were less likely than more educated women to have an optimal interval (adjusted RR = 0.68, P < 0.01). Participation in the NBCCEDP was not associated with receipt of follow-up within an optimal diagnostic interval.

CONCLUSIONS

Compared with women with greater educational attainment, high school graduates were less likely to receive follow-up within an optimal diagnostic interval, as were younger (≤ 30 years) women compared with older women. Participation in the NBCCEDP was not associated with receipt of care within an optimal diagnostic interval.

Mailed self-sample HPV testing kits to improve cervical cancer screening in a safety net health system: protocol for a hybrid effectiveness-implementation randomized controlled trial

BACKGROUND

Almost 20% of U.S. women remain at risk for cervical cancer due to their inability or unwillingness to participate in periodic clinic-based screening. Self-sampling has been shown to be an effective strategy for screening women for high-risk human papillomavirus (HR-HPV) infection in specific contexts. However, its effectiveness among medically underserved women in safety net health systems has not been evaluated. Furthermore, it is also unclear whether implementation strategies such as patient navigation can be used to improve the success of self-sample screening programs by addressing patient-level barriers to participation.

METHODS/DESIGN

The Prospective Evaluation of Self-Testing to Increase Screening (PRESTIS) trial is a hybrid type 2 effectiveness-implementation pragmatic randomized controlled trial of mailed self-sample HPV testing. The aim is to assess the effectiveness of mailed self-sample HPV testing kits to improve cervical cancer screening participation among patients in a safety net health system who are overdue for clinic-based screening, while simultaneously assessing patient navigation as an implementation strategy. Its setting is a large, urban safety net health system that serves a predominantly racial/ethnic minority patient population. The trial targets recruitment of 2268 participants randomized to telephone recall (enhanced usual care, n = 756), telephone recall with mailed self-sample HPV testing kit (intervention, n = 756), or telephone recall with mailed self-sample HPV testing kit and patient navigation (intervention + implementation strategy, n = 756). The primary effectiveness outcome is completion of primary screening, defined as completion and return of mailed self-sample kit or completion of a clinic-based Pap test. Secondary effectiveness outcomes are predictors of screening and attendance for clinical follow-up among women with a positive screening test. Implementation outcomes are reach, acceptability, fidelity, adaptations, and cost-effectiveness.

DISCUSSION

Hybrid designs are needed to evaluate the clinical effectiveness of self-sample HPV testing in specific populations and settings, while incorporating and evaluating methods to optimize its real-world implementation. The current manuscript describes the rationale and design of a hybrid type 2 trial of self-sample HPV testing in a safety net health system. Trial findings are expected to provide meaningful data to inform screening strategies to ultimately realize the global goal of eliminating cervical cancer.

Human papillomavirus vaccination practices and perceptions among Ghanaian Healthcare Providers: A qualitative study based on multi-theory model

BACKGROUND

Healthcare providers' (HCPs) recommendations for the Human Papillomavirus (HPV) vaccine are likely to increase the vaccination uptake. However, little is known about Ghanaian HCPs' general practices regarding HPV vaccination. We used Multi-Theory Model (MTM) constructs (i.e. participatory dialogue, behavioral confidence, environment, social and emotional transformation) to examine Ghanaian HCPs' attitudes towards HPV vaccination and their vaccination recommendation practices.

METHODS

We conducted three, 60-minute focus group discussions (FGDs) with HCP in the second-largest government hospital in Ghana. Sixteen semi-structured open-ended questions based on MTM constructs were used to guide the FGDs. We explored HCPs' general knowledge about HPV, vaccination recommendation behavior, physical environment, and socio-cultural factors associated with the HPV vaccination. Data from the FGDs were transcribed and thematically coded using NVivo software.

RESULTS

The sample of (n = 29) HCPs consisting of males (n = 15) and females (n = 14) between the ages of 29 and 42 years participated in the FGDs. Our analyses showed that HCPs (a) rarely offered HPV vaccination recommendations, (b) showed varied understanding about who should be vaccinated regarding age eligibility, gender, and infection status. Perceived barriers to HPV vaccination include (a) low urgency for vaccination education due to competing priorities such as malaria and HIV/AIDS; (b) lack of data on HPV vaccination; (c) lack of awareness about the vaccine safety and efficacy; (c) lack of HPV vaccine accessibility and (d) stigma, misconceptions and religious objections. HCPs expressed that their motivation for counseling their clients about HPV vaccination would be increased by having more knowledge about the vaccine's efficacy and safety, and the involvement of the parents, chiefs, churches, and opinion leaders in the vaccination programs.

CONCLUSION

The study's findings underscore the need for a comprehensive HPV vaccination education for HCPs in Ghana. Future HPV vaccination education programs should include information about the efficacy of the vaccine and effective vaccination messages to help mitigate HPV vaccine-related stigma.

Parental intent to initiate and complete the human papillomavirus vaccine series in the USA: a nationwide, cross-sectional survey

BACKGROUND

Human papillomavirus (HPV) vaccine uptake among US adolescents is primarily dependent on the intent of their parents. To the best of our knowledge, an analysis quantifying parental intent to initiate and complete the HPV vaccine series in the USA at both the national and state level has not been done. We aim to estimate parental intent to initiate and complete the HPV vaccine series at the national-level and state-level and to identify reasons for lack of intent to initiate and complete the vaccine series.

METHODS

This cross-sectional study uses data from the adolescent component of the 2017-18 National Immunization Survey (NIS-Teen). Study participants were parents or caregivers of US adolescents aged 13-17 years, who were most knowledgeable about the immunisation status of the adolescents. The primary outcome was parental intent to vaccinate the adolescent in the next 12 months. The secondary outcomes were (1) the prevalence of reasons given for lack of intent to initiate and complete the HPV vaccine series, and (2) the relationship between receiving a recommendation from a health-care provider to vaccinate and intent to initiate the vaccination series. We computed national-level and state-level estimates for parental lack of intent to initiate and to complete the vaccine series; population-level estimates were derived using survey weights. A survey design-adjusted Wald F test was used for bivariate analysis. A multivariate logistic regression model was used to examine the association between health-care provider recommendation and parental intent to initiate the series. Analyses were stratified by history of health-care provider recommendation to initiate the HPV vaccine series.

FINDINGS

In 2017-18, the parent or caregiver of 82 297 US adolescents aged 13-17 years completed the NIS-Teen survey. 30 558 (37·1%) were unvaccinated and 9073 (10·8%) received only one HPV vaccine dose. Parents of 58·0% (17 171/29 086) of unvaccinated adolescents with data available on parental intent had no intention to initiate the HPV vaccine series. More than 65% of parents of unvaccinated adolescents in Idaho, Kansas, Michigan, Montana, Nebraska, North Dakota, Oklahoma, and Utah had no intention to initiate the HPV vaccine series. Parents of 23·5% (2166/9072) of initiators with data available on parental intent had no intention to complete the HPV vaccine series. More than 30% of parents in Arkansas, Florida, Georgia, Hawaii, Idaho, Utah, and West Virginia did not intend to complete the HPV vaccine series, whereas in the District of Columbia (11·2% [22/166]) and Rhode Island (20·4% [21/112]) parental lack of intent was relatively low (both regions have an HPV vaccine mandate). The most common reason for lack of intent among parents to initiate the vaccine for unvaccinated adolescents was safety concerns (22·8% [4182/16 455]); lack of a recommendation from a health-care provider (22·2% [440/1944]) was the most frequently cited reason for absence of intent to complete the series among parents of adolescents who received only one HPV vaccine dose. Receipt of a recommendation from a health-care provider was associated with greater odds of parental intent to initiate the HPV vaccine series (odds ratio 1·11, 95% CI 1·01-1·22). 45·5% (13 156/29 086) of parents of unvaccinated adolescents had reportedly received an HPV vaccine recommendation. Parents of 60·6% (7938/13 156) of unvaccinated adolescents with a recommendation from a health-care provider and data available on parental intent had no intention to initiate the series.

INTERPRETATION

Lack of parental intent to initiate and complete the HPV vaccine series for adolescents is a major public health concern in the USA. Combating vaccine safety concerns and strong recommendations from health-care providers could improve the currently suboptimal HPV vaccination coverage.

Qualitative assessment of knowledge and attitudes towards cervical cancer screening among male Latino immigrants in Houston, Texas

Background

Male spouses and partners play an important role in determining a woman’s willingness to participate in cervical cancer screening. However, the attitudes and behaviors by which they influence a woman’s decision to undergo Pap testing remain poorly understood.

Methods

A series of semi-structured, qualitative interviews were conducted in Spanish with 19 recent Latino immigrants in Houston, Texas. The interview format was designed to establish each individual’s pattern of engagement with the United States healthcare system, assess baseline knowledge of cervical cancer screening and evaluate attitudes and patterns of communication with their female partners regarding health care. Interview questions were constructed using principles of the Theory of Reasoned Action. All interviews were conducted in Spanish. After translation, responses were coded and scored with the goal of identifying themes and key observations.

Results

Most subjects reported few, if any, interactions with the healthcare system since their arrival in the United States. Although most participants reported being aware that women should be seen by their doctors regularly, fewer than half could clearly indicate the purpose of a Pap test or could state with certainty the last time their female partner had undergone screening. Multiple subjects expressed a general distrust of the health care system and concern for its costs. Approximately half of subjects reported that they accompanied their female partner to the health care provider’s office and none of the participants reported that they were present in examination rooms at the time their partner underwent screening. Multiple participants endorsed that there may be some concerns within their community regarding women receiving frequent gynecologic care and distrust of the healthcare system. Almost all interviewed subjects stated that while they would allow their female partners to see male physicians, they also expressed the opinion that other men might be uncomfortable with this and that women would likely be more comfortable with female physicians.

Conclusions

Strategies to enhance knowledge of HPV and cancer screening and improve trust in the health care system among male spouses or partners should be explored with the goal of promoting cervical cancer screening among immigrant Latinx populations.

Multi-Theory Model and Predictors of Likelihood of Accepting the Series of HPV Vaccination: A Cross-Sectional Study among Ghanaian Adolescents

HPV vaccines are efficacious in preventing HPV related cancers. However, the vaccination uptake in Ghana is very low. Studies that utilize theoretical frameworks to identify contributory factors to HPV vaccination uptake in Ghana are understudied. We used multi-theory model (MTM) constructs to predict initiation and completion of HPV vaccination series in Ghanaian adolescents. Adolescents (n = 285) between the ages of 12 and 17 years old were recruited from four selected schools in Ghana to participate in the cross-sectional study. Linear regressions were used to analyze the data. Most participants were female (91.2%) and senior high school students (60.0%). Many of the participants had neither heard about HPV (92.3%) nor HPV vaccinations (95.4%). Significant predictors of adolescents’ likelihood of getting the first dose of HPV vaccination were perceived beliefs and change in a physical environment (p < 0.001), with each variable accounting for 6.1%and 8.8% of the variance respectively. Significant predictors of adolescents’ likelihood of completing HPV vaccination recommended series were perceived beliefs, practice for change, and emotional transformation (p < 0.001), with each variable accounting for 7.8%, 8.1%, and 1.1% of the variance respectively. Findings underscore important opportunities for developing educational interventions for adolescents in Ghana to increase the HPV vaccination uptake.

School-based human papillomavirus vaccination program for increasing vaccine uptake in an underserved area in Texas

Objective

Compare the effectiveness of community-based HPV-related education and onsite school-based vaccination versus community-based education only for increasing HPV vaccine uptake in a rural, medically underserved area.

Methods

Our cohort included 2307 Rio Grande City Consolidated Independent School District (RGCISD) middle school students from 3 schools enrolled in August 2016 and followed until April 2018. Using a quasi-experimental design, this study implemented an onsite school-based vaccination program and physician-led education on HPV and HPV vaccines for parents/guardians, school nurses/staff, and pediatric/family providers in the surrounding community (15-mile radius of RGCCISD) at 1 middle school (“intervention school”), and education-only for the remaining 2 schools (“comparison schools”). The Centers for Disease Control and Prevention's HPV-related educational materials supplemented the education. HPV vaccine status was obtained from school immunization records and the project's contracted vaccine vendor. HPV vaccine initiation and completion rates were compared pre and post intervention and between the intervention and comparison schools. Logistic regression was used to compare the odds of newly initiating/completing vaccination between the intervention and comparison schools.

Results

At baseline, the intervention school had lower HPV vaccine initiation and completion rates than the comparison schools (20.00% and 8.70% vs 28.97% and 14.56%). Post intervention, the intervention school had higher initiation and completion rates than the comparison schools (53.67% and 28.36% vs 41.56% and 20.53%). Students from the intervention school were over 3.6-times more likely to newly initiate/complete the HPV vaccinations than students from the comparison schools.

Conclusion

The school with on-site vaccination events and community-based education had a higher adolescent HPV vaccination rate compared to schools that received community-based education only.

•

Our study implemented the first school-based vaccination program in a rural, medically underserved area in Texas.

•

School-based vaccinations and community education increased the HPV vaccination rate at a greater rate than education only.

•

Our work demonstrates that middle schools provide feasible and effective settings for increasing HPV vaccination rates.

Racial/ethnic variation in the prevalence of vaccine-related human papillomavirus genotypes

Objective: There are currently three licensed human papillomavirus (HPV) vaccines that protect against cervical cancer. Here we compare the prevalence of bi-, quadri-, and nonavalent vaccine-related HPV genotypes in a multi-ethnic sample of non-Hispanic white, non-Hispanic black, Hispanic, and Asian women. Design: Patients in this analysis (n = 419) represent a subset of women with a previous abnormal Pap test participating in a clinical trial. HPV genotyping was conducted using the Roche Linear Array. Prevalent HPV genotypes were grouped according to their inclusion in each of the vaccines: bivalent (16, 18), quadrivalent (16, 18, 6, 11), and nonavalent (16, 18, 31, 33, 45, 52, 58, 6, 11). Results: The prevalence of HPV genotypes covered by the bi-/quadrivalent vaccines was lowest among non-Hispanic black (15%) and Hispanic women (20%), compared to non-Hispanic white (38%) and Asian women (38%). Across all racial/ethnic groups, a large proportion of infections (38%-49%) were with genotypes included in the nonavalent vaccine. However, the prevalence of HPV genotypes not covered by any vaccine was significantly higher among non-Hispanic black (36%) and Hispanic women (42%), compared to non-Hispanic white (24%) and Asian women (16%) (p < 0.001). Racial/ethnic differences in HPV genotype prevalence were observed when controlling for demographic and sexual behavior characteristics, as well as when restricting the analysis to women with CIN 2+. Conclusion: Our data suggest racial/ethnic differences in the prevalence of vaccine-related HPV genotypes. In particular, non-Hispanic black and Hispanic women had the lowest prevalence of HPV genotypes covered by the bi-/quadrivalent vaccines. While a large proportion of their infections were covered by the nonavalent vaccine, non-Hispanic black and Hispanic women also had the highest prevalence of HPV genotypes not covered by any vaccine.

Feasibility of Cervical Cancer Screening Utilizing Self-sample Human Papillomavirus Testing Among Mexican Immigrant Women in Harris County, Texas: A Pilot Study

Here we evaluate the acceptability and feasibility of self-sample human papillomavirus (HPV) testing (self-HPV) among a sample of predominantly Mexican immigrant women who never or sporadically attend for Pap testing. Immigrant women who had not had a Pap test in the past 3 years (n = 100) were recruited. Participants self-collected a cervical sample for HPV testing. High-risk (HR) HPV-positive women were referred for clinical follow-up. Acceptability of self-HPV was high, with 99% reporting that they would be willing to use self-HPV regularly. Nineteen women (19%) tested positive for HR-HPV. Of these, 50% obtained clinical follow-up within 3 months. For those who did not, the primary barrier to follow-up was difficulty obtaining healthcare coverage. In conclusion, self-HPV is highly acceptable to Mexican immigrant women who otherwise do not attend for Pap testing. While the approach addresses critical barriers to primary screening, questions remain as to whether uninsured HR-HPV positive women are able to attend for clinical follow-up.

Incorporating Cultural Sensitivity into Interactive Entertainment-Education for Diabetes Self-Management Designed for Hispanic Audiences

Diabetes self-management education can improve outcomes in adults with Type 2 diabetes mellitus (T2DM). However, Hispanics, a group that carries a large burden of disease, may not participate in diabetes education programs. Audience engagement with entertainment-education has been associated with improved health education outcomes and may engage and empower Hispanic users to active self-care. Successful use of entertainment-education relies on the use of characters and situations with whom the viewers can feel some sense of involvement and for Hispanic audiences is encouraged when storylines and characters are culturally sensitive. In this study, we used a mixed methods approach that included descriptive statistics of closed-ended and content analysis of open-ended questions to measure the cultural sensitivity of the telenovela portion of a novel technology-based application called Sugar, Heart, and Life (SHL). Specifically, we analyzed the responses of 123 male and female patients diagnosed with uncontrolled T2DM to determine viewer involvement with characters and situations in the telenovela, viewer perceived self-efficacy in following recommendations, as well as viewer satisfaction with the program. Our findings indicate that the SHL application achieved its goal of creating a user-friendly program that depicted realistic, culturally sensitive characters and storylines that resonated with Hispanic audiences and ultimately fostered perceived self-efficacy related to following recommendations given about healthy lifestyle changes for diabetes self-management. These findings suggest that the SHL application is a culturally sensitive health education intervention for use by Hispanic male and female individuals that may empower them in self-management of T2DM.

Abstract B78: Using the Quality in the Continuum of Cancer Care framework to develop a multilevel intervention to improve cancer screening and follow-up among the medically underserved

Introduction: Screening for cervical, colorectal, and breast cancer is an evidence-based strategy to reduce the morbidity and mortality from these cancers. However a large proportion of medically underserved individuals do not obtain regular screening. Using the Quality in the Continuum of Cancer Care (QCCC) framework, we developed and implemented a comprehensive systems design intervention to improve the delivery, uptake, and follow-up of cervical, colorectal, and breast cancer screening within a network of healthcare institutions that serve the medically underserved in Harris County, Texas.

Methods: An academic-community partnership, the Community Network for Cancer Prevention, was established between an academic cancer center, the county's safety net healthcare system, and several academic and community-based healthcare institutions. Clinical advisory boards, comprised of physicians, nurses, and public health professionals, were established for each cancer line. The QCCC framework was used to identify system-level failures that impede processes and transitions in the continuum of care from risk assessment to detection and from detection to diagnosis. Project components were developed to address the identified failures.

Results: System failures identified at the risk assessment to detection phases included 1) failure to identify individuals in need of screening, 2) inadequate capacity to screen, and 3) inadequate access to care. Failures identified at the detection to diagnosis phases included 1) failures in the screening test results notification system, 2) failures in inter-provider communication, 3) failures in inter-institutional referrals for clinical follow-up, 4) patient non-adherence, and 5) inadequate access to care. Project components to address the identified failures include community outreach, patient education, and patient navigation. Community outreach involves a community theater program aimed to increase awareness of cancer risk and the current cancer screening guidelines among medically underserved individuals in the larger community; healthcare access navigators available at each performance assist audience members in applying for healthcare coverage through the safety net healthcare system. Patient education involves using the electronic medical record to identify patients due or past due for cervical, colorectal, and/or breast cancer screening. These patients are then targeted for a video-based patient education intervention while they wait to be seen by their healthcare provider. Motivational messaging in the videos encourages patients to discuss the particular screening test with their provider. Finally, patient navigation involves a team of navigators who actively communicate with patients and providers to ensure follow-up among patients with an abnormal screening test result. A real-time tracking database is used to monitor all screen-test positive patients as they move through the different stages of diagnostic and therapeutic follow-up.

Conclusion: The QCCC provides a systematic approach for assessing factors that influence cancer care processes at the risk assessment, screening, detection, and diagnosis phases, as well as transitions between them. Focusing on transitions between phases is particularly useful for developing systems-level interventions to improve the delivery, uptake, and follow-up of cancer screening.

Abstract PR06: Racial/ethnic variation in the prevalence of vaccine-preventable human papillomavirus genotypes

Introduction: The bi- and quadrivalent human papillomavirus (HPV) vaccines that have been on the market for ≥ 9 years protect against high-risk HPV types 16 and 18, the two HPV genotypes causally associated with ≥ 70% of cervical cancers. The recent nonavalent vaccine, which became commercially available in 2014, additionally protects against high-risk types 31, 33, 45, 52, and 58. The quadri- and nonavalent vaccines also protect against low-risk HPV types 6 and 11, which cause genital warts. The objective of this analysis is to compare the prevalence of vaccine-preventable HPV genotypes among non-Hispanic white, non-Hispanic black, Hispanic, and Asian women and determine the risk of cervical dysplasia (CIN2+) associated with the genotypes covered by each of the vaccines.

Methods: Patients in this analysis represent a subset of those participating in a clinical trial to evaluate new optical technologies for the diagnosis of cervical dysplasia. Trial participants were non-pregnant women, age ≥18 years, with a recent abnormal Pap test and were recruited at participating colposcopy clinics in Houston, El Paso, and Vancouver. As part of the parent trial, a subset of participants provided a biopsy and a cervical swab. Histologic diagnosis was based on biopsies and evaluated by a certified pathologist to represent the histology of the most severe biopsy. HPV genotyping was conducted using the Roche Linear Array. Prevalent HPV types were grouped according to their inclusion in each of the vaccines: bivalent (16, 18), quadrivalent (16, 18, 6, 11), and nonavalent (16, 18, 31, 33, 45, 52, 58, 6, 11). Women were considered to be potentially protected by a particular vaccine if all or some (in the case of multiple infections) type-specific infections were covered by the vaccine. Results for the bi- and quadrivalent vaccines were grouped given the small number of women additionally protected by the quadri- versus bivalent vaccine.

Results: The sample for this analysis (n= 419) is comprised of 206 non-Hispanic white, 39 non-Hispanic Black, 142 Hispanic, and 32 Asian women. The prevalence of HPV genotypes covered by the bi- and quadrivalent vaccines was significantly greater among non-Hispanic white (38.3%) and Asian women (37.5%) compared to non-Hispanic black (15.4%) and Hispanic women (19.7%). The increase in the proportion of women potentially protected by the nonavalent vaccine versus the bi-/quadrivalent vaccine was highest among non-Hispanic blacks (33.3% increase) followed by Hispanics (18.3% increase). However, the prevalence of HPV genotypes not covered by any vaccine was also highest among these racial/ethnic groups. Specifically, 42.3% and 35.9% of Hispanic and non-Hispanic black women, respectively, had ≥ 1 genotype not covered by any vaccine, compared to 24.3% and 15.6% among non-Hispanic white and Asian women, respectively. Non-vaccine HPV types were primarily high-risk (68%). Among women with a CIN2+ diagnosis, 37.3% had genotypes included in the bi/quadrivalent vaccine and an additional 46.7% had genotypes included in the nonavalent (but not the bi/quadrivalent) vaccine. However, 16.0% of CIN2+ diagnoses occurred among women with HPV genotypes not covered by any vaccine.

Conclusions: Our data suggest racial/ethnic differences in the proportion of women protected by the new nonavalent HPV vaccine. In particular, non-Hispanic black and Hispanic women had the greatest prevalence of HPV types covered by the nonavalent but not the bi-/quadrivalent vaccines. Nonetheless, a large proportion of women from these racial/ethnic groups were infected with genotypes not covered by any vaccine. While HPV 16 and 18 are known to cause most cervical cancers, non-vaccine genotypes were associated with 16% of CIN2+ histology, a diagnosis often requiring significant therapeutic intervention.

Abstract C17: Racial/ethnic variation in psychological distress following an abnormal Pap test

Introduction: While racial/ethnic disparities in cervical cancer incidence are mostly attributed to screening test utilization, lower rates of adherence to diagnostic and clinical follow-up after an abnormal Pap test may contribute to the higher cervical cancer mortality among racial/ethnic minorities. Psychological distress is a known contributor to non-adherence to diagnostic and therapeutic follow-up. The objective of this analysis is to explore racial/ethnic differences in distress following an abnormal Pap.

Methods: Data were collected as part of a clinical trial to evaluate emerging optical technologies for the diagnosis of cervical dysplasia. Participants were non-pregnant women, age ≥18 years, with a recent abnormal Pap test and were recruited at one of the participating colposcopy clinics. Participants answered questionnaires before and after their colposcopy procedure. Distress regarding the abnormal Pap was assessed using the Cervical Dysplasia Distress Questionnaire (CDDQ). The CDDQ measures multiple domains of distress, including those related to the colposcopy procedure (i.e., Tension and Discomfort, Embarrassment), as well as those related to having a positive screening test for cervical cancer (i.e., Health Consequences, Sexual/Reproductive Consequences). Additional items assessed participants' fear of cancer. Subscale scores range from 1 to 4, with higher scores indicating higher levels of distress. Linear regression models were built to assess the differences in distress scores among Hispanic, non-Hispanic black, and non-Hispanic white women after controlling for age and education (Model 1) and age, education, trait anxiety and depression (Model 2). Trait anxiety and depression were respectively measured using the State-Trait Anxiety Inventory for Adults and the Center for Epidemiologic Studies Depression (CESD) scale.

Results: Eighty-five Hispanic, 55 non-Hispanic black, and 86 non-Hispanic white women were included in these analyses. After controlling for age and education, there were statistically significant differences by race/ethnicity in distress scores, particularly for the domains of health consequences (p=0.02) and cancer worry (p = 0.014). In both domains, scores were highest among Hispanic women, compared to non-Hispanic black and non-Hispanic white women (mean health consequences scores = 2.45, 2.02, and 2.16, respectively; mean cancer worry scores = 2.02, 1.62, and 1.75, respectively). Furthermore, these racial/ethnic differences in domain-specific distress remained statistically significant after controlling for differences in underlying depression and trait anxiety.

Discussion: Our results suggest that there are racial/ethnic differences in levels of distress following an abnormal Pap test, particularly related to concerns over health consequences and fear of cancer. Distress scores in these domains were significantly greater among Hispanic women compared to non-Hispanic blacks and non-Hispanic whites. Hispanic women may be more likely to perceive that their abnormal Pap test will have long-term health consequences and develop into cancer. Clinical and ancillary health professionals who communicate Pap test results to Hispanic patients should reinforce messages to address unrealistic fears about disease and alleviate distress.

Avoidable tragedies: Disparities in healthcare access among medically underserved women diagnosed with cervical cancer

BACKGROUND

The purpose was to identify barriers including logistical and health belief correlates of late stage presentation of cervical cancer (CxCa) among medically underserved women presenting to a safety net health care system.

METHODS

Women presenting with newly diagnosed CxCa were asked to complete a detailed health belief survey that included questions about barriers to care and their knowledge of CxCa. All information was collected prior to initiating cancer treatment. Comparisons were made among women diagnosed at early stages of disease amendable to surgical treatment (≤IB1) and those diagnosed at a stage requiring local-regional or systemic/palliative treatment (≥IB2).

RESULTS

Among the 138 women, 21.7% were diagnosed with ≤lB1 disease, while 78.3% were diagnosed with ≥IB2 disease. Late-stage diagnosis was associated with a greater number of emergency room (ER) visits (p<.001) and blood transfusions (p<.001) prior to diagnosis. Compared to 88% with ≤lB1 disease, only 53% of patients with ≥IB2 disease had a car (p=.003). Women with ≥IB2 disease were more likely to be without a primary care provider (75.0% vs. 42.3%, p=.001).

CONCLUSION

Access to transportation and lack of a regular primary care provider or a medical home are associated with late-stage of CxCa at diagnosis. Many medically underserved women continue to use the ER as their primary source of health care, and as a result their CxCa is diagnosed in advanced stages, with higher medical costs and lower chances of cure. The lack of Medicaid expansion in Texas may result in a worsening of this situation.

Abstract B11: Prevalent high-risk HPV genotypes among Hispanic women along the Texas-Mexico border

Introduction: There are 13 oncogenic (high-risk) types of human papillomavirus (HPV) that are causally associated with cervical cancer, specifically types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68. HPV 16 and 18 are causally related to 70% of cervical cancers and 50% of precancerous lesions worldwide and are the primary targets for the two commercially-available HPV vaccines. However, there is evidence that HPV 16 and 18 are detected in a significantly lower proportion of high-grade cervical lesions among Hispanic women when compared to non-Hispanic white women. The purpose of this study was to identify prevalent high-risk (HR) HPV genotypes among Hispanic women living along the Texas-Mexico border.

Methods: We analyzed data from a subset of participants of an ongoing clinical trial evaluating molecular imaging for the identification of cervical neoplasia. Trial participants included women with an abnormal Pap test presenting for colposcopy at an academic medical center in El Paso, Texas. Cervical samples were collected and tested for HPV using the Roche Linear Array HPV genotyping test, which identifies individual HPV genotypes. Histologic diagnoses are based on biopsies evaluated by a certified pathologist and represent the histology of the most severe biopsy. An interviewer- administered questionnaire was used to ascertain demographic characteristics and behavioral risk factors.

Results: To date, we have performed HPV genotyping for 57 participants. Of these, 53 (93%) were of Hispanic origin. Among Hispanic women, the median age was 32.3 years (range 21.1-64.5), 43% were born in Mexico, 26% were married or living as married, 55% had a high school education or less, 53% had an annual household income of less than $20,000, and 19% reported having received at least one dose of the HPV vaccine. Eighty seven percent of women (n=46) were infected with HPV (49% with a single strain and 51% with multiple strains) and 66% (n = 35) were infected with HR-HPV (66% with a single strain and 34% with multiple strains). The most prevalent HR-HPV types were HPV 31 (present in 31% of HR-HPV positive samples), HPV 16 (29%), and HPV 33 (23%). Among women with CIN 2 and 3 (n=8), the most common HR-HPV types were HPV 16 (present in 5 of 8 CIN2/3 samples) and HPV 31 (in 3 of 8). HPV 33, 35, and 66 were each present in 2 of 8 CIN 2/3 samples.

Conclusion: HPV 16 was present in 29% of women who tested positive for HR-HPV and 63% of women with CIN 2/3. However, the most prevalent genotype in our sample was HPV 31 (present in 31% of women who tested positive for HR-HPV). This genotype was present in 38% of women with CIN2/3. HPV 18 was not present in any samples. Although limited by our small sample size, these preliminary data suggest that the distribution of HPV genotypes among Hispanic women along the Texas-Mexico border may be different from that of other populations and includes genotypes that are not targeted by the two commercially-available HPV vaccines.

Acceptability of self-sample human papillomavirus testing among medically underserved women visiting the emergency department

OBJECTIVE

Self-sample human papillomavirus (HPV) testing in public emergency departments (EDs) may be a viable strategy to opportunistically screen women who otherwise do not attend for regular Papanicolaou test-based cervical cancer screening. We describe the acceptability of self-sample HPV testing among women presenting to two high-volume, urban EDs that primarily care for the medically underserved.

METHODS

In 2014, a total of 210 women 21 years of age and older were recruited from two public ED waiting areas following a two-stage cluster sampling design. Questionnaire items inquired about demographics, healthcare access and utilization, history of cervical cancer screening, and acceptability of self-sample HPV testing. Descriptive analyses were performed.

RESULTS

Overall, 34.8% of participants were considered screening non-attendees based on their adherence to the current guidelines for Pap testing every three years. Acceptability of self-sample HPV testing was high, with over 85% of participants reporting that they would be willing to use the test if available. A smaller proportion (58%) was deemed likely to accept self-sample HPV testing in a public ED restroom setting. Primary concerns expressed by women were that the sampling may not be done correctly (64%) and that they may not know how to perform the sampling (39%).

CONCLUSIONS

Opportunistic self-sample HPV testing is acceptable to women seeking care at a high-volume, urban emergency care center. The use of this intervention potentially offers a unique strategy to improve cervical cancer screening among high-risk women who otherwise do not attend for regular screening.

Implementing targeted cervical cancer screening videos at the point of care

OBJECTIVE

To develop and implement educational videos to improve cervical cancer health literacy for patients within a safety net healthcare system.

METHODS

Testimonial-style videos were developed with the goal of describing the Pap test to low literacy patients and motivating them to participate in regular cervical cancer screening. Nurses were trained to use the electronic medical record to identify patients due or past due for a Pap test according to the current screening guidelines. They played the video for all eligible patients as they waited to be seen by their physician in clinical examination rooms.

RESULTS

Four 2-minute videos were developed in English, Spanish, and Vietnamese. Videos were made available on desktop computers in 458 exam rooms at 13 community health centers.

CONCLUSION

Integration of educational videos into the workflow of high-volume community health centers is feasible. Future work will focus on optimizing uptake of the videos as well as assessing their efficacy for improving cervical cancer health literacy.

PRACTICE IMPLICATIONS

Integrating targeted videos into patient flow may be a feasible way to address health literacy barriers to cervical cancer screening within a busy workflow environment.

Abstract C90: Colorectal cancer among Hispanics in the U.S.: Nativity disparities in stage at diagnosis and survival

Introduction: Compared to non-Hispanic whites, Hispanics in the U.S. are significantly more likely to be diagnosed with late-stage colorectal cancer (CRC) and have a higher CRC-specific mortality hazard. While the low CRC screening rates among Hispanics (29%) are known to be lowest among foreign-born individuals (22%), few studies have examined CRC disparities by nativity. Here we examine differences in late-stage CRC diagnosis and survival among U.S.- and foreign-born Hispanics.

Methods: We used data from the Surveillance, Epidemiology, and End Results (SEER) program. Cases were Hispanic men and women diagnosed with primary invasive CRC between 1988 and 2008. Nativity was based on place of birth and was categorized as U.S.- versus foreign-born. Missing nativity values were imputed using multiple imputation by logistic regression, a strategy with high sensitivity (91%) and specificity (90%) for detecting foreign-born status. Distant and regional tumors were classified as late-stage; local tumors were classified as early-stage. Multivariable logistic regression was used to assess the association between late-stage diagnosis and nativity after adjusting for demographic characteristics (age at diagnosis and gender) and anatomic subsite (proximal, distal, rectum, or other). Multivariable Cox regression was used to assess the association between CRC-specific survival and nativity after adjusting for demographic characteristics, tumor characteristics (stage at diagnosis and anatomic subsite), and receipt of cancer-directed therapy (surgery and radiation).

Results: Fifty eight percent of cases of invasive CRC among Hispanics were diagnosed at a late stage and 63% of cases were among foreign-born individuals. Foreign-born Hispanics were significantly more likely than U.S.-born Hispanics to have a late-stage diagnosis after adjusting for demographic characteristics (adjusted odds ratio=1.08, p&lt;0.001). However, the demographics-adjusted mortality hazard was similar among foreign- and U.S.-born Hispanics (adjusted hazard ratio [AHR]=0.99, p-value=0.790). After adjusting for tumor characteristics, foreign-born Hispanics had improved survival compared to their U.S.-born counterparts (AHR=0.94, p=0.005). Their survival advantage remained significant after adjusting for both tumor characteristics and cancer-directed therapy (AHR=0.92, p&lt;0.001).

Conclusions: The increased prevalence of late-stage diagnosis among foreign-born Hispanics is likely a reflection of their reduced screening rates relative to Hispanics born in the U.S. However, the increased risk of late-stage diagnosis did not result in an increased mortality hazard among foreign-born Hispanics. In fact, survival was better among foreign- versus U.S.-born Hispanics after adjusting for stage at diagnosis and receipt of cancer-directed therapy. Similar patterns have been found for cervix and overall cancer survival and may be attributed to changes in risk profiles associated with acculturation (e.g., higher rates of smoking, obesity, alcohol consumption, and poor nutrition). Additionally, U.S.-born Hispanics have a higher prevalence of chronic diseases (e.g., diabetes, obesity, heart disease) that may negatively affect cancer survival. Our results suggest that the overlap between race/ethnicity and nativity status should not be overlooked in cancer health disparities research.

Nativity differences in behaviors associated with high-risk HPV infection among Hispanic women in Houston, Texas, USA

While Hispanics in the U.S. are a population with significant within-group heterogeneity, epidemiologic studies often aggregate Hispanics into one homogenous group without considering differences by nativity. The objective of this study is to evaluate nativity differences in the risk behavior profile associated with prevalent high risk human papillomavirus (HR-HPV) among U.S.- and foreign-born Hispanic women. Using a clinical trial dataset, we compare risk behavior and HR-HPV infection patterns among U.S.- and foreign-born participants and assess factors associated with infection in each group. While the prevalence of HR-HPV infection was similar among U.S.- and foreign-born participants, U.S.-born cases had a higher HR-HPV risk profile. The similar prevalence of HR-HPV despite foreign-born women's lower risk profile suggests a role for unmeasured risk factors among foreign-born Hispanics. More importantly, nativity differences in behavioral risk factors associated with HR-HPV suggest the need to further research cervical cancer risk factors among disaggregated Hispanic subgroups.
