Dentists are well-positioned to discuss oral health issues related to Human Papillomavirus (HPV) and recommend the HPV vaccine to their patients, mainly because the HPV virus causes oropharyngeal cancers.. We assessed Los Angeles (LA) County dentists opinions on discussing HPV-related oral health issues and recommending the HPV vaccine to their patients. We tested if opinions differed between dentists whose primary patient population was only adults versus children and adults. We mailed a 19-item survey to 2000 randomly sampled LA County dentists for this cross-sectional study. The primary outcome variable was a summary opinion score of 7 opinion statements. We ran descriptive, bivariate comparisons and adjusted linear regression models. Overall, 261 dentists completed the survey. A majority (58.5%) worried they would lose patients if they recommended the vaccine; 49% thought dentists were not appropriate to educate, counsel, or advise on HPV-related issues; 42% were concerned about the safety of the vaccine; and 40% did not feel comfortable recommending the vaccine. The mean summary opinion score was 21.4 ± 5.4 for the total sample. Regression analysis showed no differences in opinions between dentists whose primary patient population was only adults versus children and adults (Coefficient = 0.146, p = 0.83). Overall, the responding dentists were not very favorable about discussing oral health-related HPV issues and recommending the HPV vaccine to their patients. Additionally, the overall opinions were similar between dentists whose primary patient population was only adults versus children and adults.

INTRODUCTION: At-home colorectal cancer (CRC) screening is an effective way to reduce CRC mortality, but screening rates in medically underserved groups are low. To plan the implementation of a pragmatic randomized trial comparing two population-based outreach approaches, we conducted qualitative research on current processes and barriers to at-home CRC screening in 10 community health centers (CHCs) that serve medically underserved groups, four each in Massachusetts and California, and two tribal facilities in South Dakota. METHODS: We conducted 53 semi-structured interviews with clinical and administrative staff at the participating CHCs. Participants were asked about CRC screening processes, categorized into eight domains: patient identification, outreach, risk assessment, fecal immunochemical test (FIT) workflows, FIT-DNA (i.e., Cologuard) workflows, referral for a follow-up colonoscopy, patient navigation, and educational materials. Transcripts were analyzed using a Rapid Qualitative Analysis approach. A matrix was used to organize and summarize the data into four sub-themes: current process, barriers, facilitators, and solutions to adapt materials for the intervention. RESULTS: Each sites process for stool-based CRC screening varied slightly. Interviewees identified the importance of offering educational materials in English and Spanish, using text messages to remind patients to return kits, adapting materials to address health literacy needs so patients can access instructions in writing, pictures, or video, creating mailed workflows integrated with a tracking system, and offering patient navigation to colonoscopy for patients with an abnormal result. CONCLUSION: Proposed solutions across the three regions will inform a multilevel intervention in a pragmatic trial to increase CRC screening uptake in CHCs.

OBJECTIVE: Although vaccination confidence is declining globally, there is little detailed information from low- and middle-income countries about factors influencing routine vaccination behavior in these contexts. METHODS: In mid-2022, we surveyed people who gave birth in Kenya between 2017-2022, and asked them about their childrens vaccination history and about hypothesized correlates of vaccination per the Behavioural and Social Drivers of Vaccination model. RESULTS: Of 873 children in this sample, 117 (13%) were under-vaccinated (i.e., delayed or missing vaccine dose(s)) - and under-vaccination was more common among births during the COVID-19 pandemic (2020-2022) versus pre-pandemic (2017-2019). In multi-level multivariable models, children of respondents who expressed concerns about serious side effects from vaccines had significantly higher odds of missed vaccine dose(s) (aOR 2.06, 95 % CI 1.14-3.72), and there was a strong association between having more safety concerns now versus before the COVID-19 pandemic (aOR missed dose(s) 4.44, 95 % CI 1.71-11.51; aOR under-vaccination 3.03, 95 % CI 1.28-7.19). People with greater trust in health workers had lower odds of having a child with missed vaccine dose(s) (aOR 0.85, 95 % CI 0.75-0.97). People who reported higher patient-centered quality of vaccination care had much lower odds of having children with delayed or missed vaccine dose(s) (aOR missed dose(s) 0.14, 95 % CI 0.04-0.58; aOR under-vaccination 0.27, 95 % CI 0.10-0.79). CONCLUSIONS: These findings highlight potential strategies to improve vaccine coverage: greater focus on patient-centered quality of care, training healthcare workers on how to address safety concerns about vaccines, and building trust in the health care system and in health workers.

BackgroundReal-time, rapid assessment of barriers to care experienced by patients can be used to inform relevant health care legislation. In recent years, online communities have become a source of support for patients as well as a vehicle for discussion and collaboration among patients, clinicians, advocates, and researchers. The Breast Cancer Social Media (#BCSM) community has hosted weekly Twitter chats since 2011. Topics vary each week, and chats draw a diverse group of participants. Partnering with the #BCSM community, we used Twitter to gather data on barriers to care for patients with metastatic breast cancer and potential policy solutions. Metastatic breast cancer survival rates are low and in large part conditioned by time-sensitive access to care factors that might be improved through policy changes. ObjectiveThis study was part of an assessment of the barriers to care for metastatic breast cancer with the goal of offering policy solutions for the legislative session in California. MethodsWe provided 5 questions for a chat specific to metastatic breast cancer care barriers and potential policy solutions. These were discussed during the course of a #BCSM chat on November 18, 2019. We used Symplur (Symplur LLC) analytics to generate a transcript of tweets and a profile of participants. Responses to the questions are presented in this paper. ResultsThere were 288 tweets from 42 users, generating 2.1 million impressions during the 1-hour chat. Participants included 23 patient advocates (most of whom were patients themselves), 7 doctors, 6 researchers or academics, 3 health care providers (2 nurses, 1 clinical psychologist), and 2 advocacy organizations. Participants noted communication gaps between patient and provider especially as related to the need for individualized medication dosing to minimize side effects and maximize quality of life. Timeliness of insurance company response, for example, to authorize treatments, was also a concern. Chat participants noted that palliative care is not well integrated into metastatic breast cancer care and that insurance company denials of coverage for these services were common. Regarding financial challenges, chat participants mentioned unexpected copays, changes in insurance drug formularies that made it difficult to anticipate drug costs, and limits on the number of physical therapy visits covered by insurance. Last, on the topic of disability benefits, participants expressed frustration about how to access disability benefits. When prompted for input regarding what health system and policy changes are necessary, participants suggested a number of ideas, including expanding the availability of nurse navigation for metastatic breast cancer, developing and offering a guide for the range of treatment and support resources patients with metastatic breast cancer, and improving access to clinical trials. ConclusionsRapid assessments drawing from online community insights may be a critical source of data that can be used to ensure more responsive policy action to improve patient care.

PurposeE-cigarettes are the most commonly used tobacco product among youth in the United States. Yet evidence-based prevention programming is limited due to the rapid onset of this threat. Community-based efforts to address vaping largely target youth in school settings. Although parents can play an important role in youth tobacco control efforts, messages about the dangers of vaping, use among adolescents, and strategies for intervening have not reached many Spanish-speaking parents in low-income Latinx communities. Our community-academic team developed e-cigarette prevention programming for use by promotor/as de salud to address this unmet need.MethodsDuring the 1-year project, the team worked closely with a Project Advisory Committee to: review existing evidence-informed materials; conduct focus groups with parents, youth and promotor/as to guide program development; develop a curriculum to prepare promotor/as to educate low-literacy, Spanish-speaking parents about vaping; craft Spanish language resources for promotor/as to use in community education sessions; train 61 promotor/as to deliver the program; and support program delivery to 657 community members.ResultsFocus groups with promotor/as and community members, key-informant interviews, and brief surveys informed program development and assessment. Community member feedback was essential to development of appropriate materials. Promotor/as demonstrated significant pre- to post- training increases in e-cigarette knowledge and confidence in delivering vaping prevention education. Community members demonstrated a mastery of basic e-cigarette concepts and expressed intention to discuss vaping with their children.ConclusionsPromotor/a-led programming for parents represents a promising approach to vaping prevention and control in the Latinx community.

Patients from historically under-represented racial and ethnic groups are enrolled in cancer clinical trials at disproportionately low rates in the USA1-3. As these patients often have limited English proficiency4-7, we hypothesized that one barrier to their inclusion is the cost to investigators of translating consent documents. To test this hypothesis, we evaluated more than 12,000 consent events at a large cancer centre and assessed whether patients requiring translated consent documents would sign consent documents less frequently in studies lacking industry sponsorship (for which the principal investigator pays the translation costs) than for industry-sponsored studies (for which the translation costs are covered by the sponsor). Here we show that the proportion of consent events for patients with limited English proficiency in studies not sponsored by industry was approximately half of that seen in industry-sponsored studies. We also show that among those signing consent documents, the proportion of consent documents translated into the patient's primary language in studies without industry sponsorship was approximately half of that seen in industry-sponsored studies. The results suggest that the cost of consent document translation in trials not sponsored by industry could be a potentially modifiable barrier to the inclusion of patients with limited English proficiency.

Parent reminders have produced modest improvements in human papillomavirus (HPV) vaccination among adolescents. However, little prior research has compared the effectiveness and feasibility of different HPV reminder types in resource-limited settings. We conducted a quasi-experimental study (2016-2017) to evaluate the effectiveness of three parent reminder types (mailed letters, robocalls, text messages) on next-dose HPV vaccine receipt among 12-year-olds in a large Federally Qualified Health Center in Los Angeles County. Six clinics were matched into three pairs: randomly assigning one clinic within each pair to intervention and control. Intervention clinics were randomly assigned to deliver one of the three parent reminder types. We calculated rates of next-dose vaccine receipt and assessed intervention effects using logistic regression models. We calculated the proportion of each type of reminder successfully delivered as a feasibility measure. The study sample comprised 877 12-year-olds due for an HPV vaccine dose (47% female, >85% Latino). At 4-month follow-up, 23% of intervention patients received an HPV vaccine dose compared to only 12% of control patients. Overall, receipt of any reminder increased rates of the next-needed HPV vaccine compared to usual care (p = 0.046). Significant improvements were observed for text reminders (p = 0.036) and boys (p = 0.006). Robocalls were the least feasible reminder type. Text message reminders are feasible and effective for promoting HPV vaccination. Future research is needed to assess the effectiveness and feasibility of reminders compared to other vaccine promotion strategies.

BackgroundWe sought to evaluate the trends of HPV vaccination between 03/2019-09/2021 and whether the impact of the COVID pandemic on HPV vaccination varied by race/ethnicity and neighborhood deprivation index (NDI).MethodsElectronic medical records at Kaiser Permanente Southern California were used to assess monthly volume of HPV vaccine doses administered among children aged 9-12.9yrs, and up-to-date coverage (% vaccinated) by age 13 between 03/2019-09/2021. Modified Poisson models were used to evaluate the interactions between race/ethnicity, NDI and the pandemic periods on HPV vaccine coverage.ResultsHPV vaccine doses administered in 2020/2021 have returned to the 2019 level after the initial drop. The average up-to-date coverage in 05/2021-09/2021 (54.8%) remained lower than the pre-pandemic level (58.5%). The associations between race/ethnicity, NDI and HPV vaccine coverage did not vary due to the pandemic.ConclusionHPV vaccine promotion efforts are needed to address COVID-19 pandemic's lasting impact on HPV vaccination coverage.

BackgroundHuman papillomavirus (HPV) vaccines can significantly reduce the burden of HPV-associated cancers, but remain underutilized. We evaluated a multi-component, system-level intervention to improve HPV vaccination in a large Federally Qualified Health Center (FQHC) that serves a primarily low income Latino population.MethodsFrom January 2015 through March 2017, we evaluated the effectiveness of a multi-component, system-level intervention to improve HPV vaccination rates in eight clinics randomly assigned to study condition (four intervention, four usual care). The intervention included parent reminders for HPV vaccine series completion, provider training, clinic-level audit and feedback, and workflow modifications to reduce missed opportunities for vaccination. Using a difference-in-differences approach, we compared HPV vaccination rates among patients, ages 11 to 17 during a 12-month preintervention period and a 15-month intervention period. Linear mixed models were used to estimate intervention effects on vaccine initiation and completion.ResultsThe sample included approximately 15,000 adolescents each quarter (range 14,773-15,571; mean age 14 years; 51% female, 88% Latino). A significantly greater quarterly increase in HPV vaccine initiation was observed for intervention compared with usual care clinics (0.75 percentage point greater increase, P < 0.001), corresponding to 114 additional adolescents vaccinated per quarter. The intervention led to a greater increase in HPV vaccine completion rates among boys (0.65 percentage point greater increase, P < 0.001), but not girls.ConclusionsOur system-level intervention was associated with modest improvements in HPV vaccine initiation overall and completion among boys.ImpactStudy findings have implications for reducing HPV-related cancers in safety net populations.

BackgroundIntroduction of the human papillomavirus (HPV) vaccine in 2006 was a game-changing advance in cancer control. Despite the vaccine's potential cancer prevention benefits, uptake remains low. We utilized a randomized design to evaluate a multicomponent intervention to improve HPV vaccine uptake among low-income, ethnic minority adolescents seeking services through a county health department telephone hotline.MethodsHotline callers who were caregivers of never-vaccinated adolescents (11-17 years) were randomized by call-week to intervention or control conditions. The intervention included brief telephone and print education, delivered in multiple languages, and personalized referral to a low-cost/free vaccine provider. Participants completed baseline (n = 238), 3-month (n = 215), and 9-month (n = 204) telephone follow-up surveys.ResultsHPV vaccine initiation rates increased substantially by 9-month follow-up overall, although no differences were observed between intervention and control groups (45% vs. 42%, respectively, P > 0.05). We also observed significant improvements in perceived HPV risk, barriers to vaccination, and perceived knowledge in both study conditions (P < 0.05).ConclusionsA low-intensity county hotline intervention did not produce a greater increase in HPV vaccination rates than routine practice. However, 44% of unvaccinated adolescents in both conditions received at least one dose of the vaccine, which can be viewed as a successful public health outcome. Future studies should evaluate more intensive interventions that address accessing and utilizing services in complex safety net settings.ImpactStudy results suggest the need for investigators to be aware of the potential priming effects of study participation, which may obscure the effect of low-intensity interventions.

BackgroundNonalcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease and cirrhosis. NAFLD is mediated by changes in lipid metabolism and known risk factors include obesity, metabolic syndrome, and diabetes. The aim of this study was to better understand differences in the lipid composition of individuals with NAFLD compared to controls, by performing direct infusion lipidomics on serum biospecimens from a cohort study of adults in Mexico.MethodsA nested case-control study was conducted with a sample of 98 NAFLD cases and 100 healthy controls who are participating in an on-going, longitudinal study in Mexico. NAFLD cases were clinically confirmed using elevated liver enzyme tests and liver ultrasound or liver ultrasound elastography, after excluding alcohol abuse, and 100 controls were identified as having at least two consecutive normal alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (

BackgroundLiver cancer is one of the most rapidly increasing cancers in the United States, and hepatocellular carcinoma (HCC) is its most common form. Disease burden and risk factors differ by sex and race/ethnicity, but a comprehensive analysis of disparities by socioeconomic status (SES) is lacking. We examined the relative impact of race/ethnicity, sex, and SES on HCC incidence, stage, and survival.MethodsWe used Surveillance, Epidemiology, and End Results (SEER) 18 data to identify histologically confirmed cases of HCC diagnosed between January 1, 2000 and December 31, 2015. We calculated age-adjusted HCC incidence, stage at diagnosis (local, regional, distant, unstaged), and 5-year survival, by race/ethnicity, SES and sex, using SEER*Stat version 8.3.5.ResultsWe identified 45,789 cases of HCC. Incidence was highest among low-SES Asian/Pacific Islanders (API; 12.1) and lowest in high-SES Whites (3.2). Incidence was significantly higher among those with low-SES compared with high-SES for each racial/ethnic group (P < 0.001), except American Indian/Alaska Natives (AI/AN). High-SES API had the highest percentage of HCC diagnosed at the local stage. Of all race/ethnicities, Blacks had the highest proportion of distant stage disease in the low- and high-SES groups. Survival was greater in all high-SES racial/ethnic groups compared with low-SES (P < 0.001), except among AI/ANs. Black, low-SES males had the lowest 5-year survival.ConclusionsWith few exceptions, HCC incidence, distant stage at diagnosis, and poor survival were highest among the low-SES groups for all race/ethnicities in this national sample.ImpactHCC prevention and control efforts should target low SES populations, in addition to specific racial/ethnic groups.

PurposeYoung adulthood is characterized by changes in health care decision-making, insurance coverage, and sexual risk. Although the human papillomavirus (HPV) vaccine is now approved for adults up to age 45, and catch-up vaccination is currently recommended up through age 26, vaccination rates remain low in young adults. This study explored perspectives on HPV vaccination among young adults receiving care at the student health center of a large public university.MethodsWe conducted semi-structured interviews (n = 27) and four focus groups with female and male undergraduate and graduate students (n = 18) and semi-structured interviews with health care providers (n = 6). Interviews and focus groups explored perceived risk of HPV infection, benefits of the HPV vaccine, and motivations for and barriers to HPV vaccination.ResultsMany young adults cited their parents' views and recommendations from medical providers as influential on their decision-making process. Students perceived that cervical cancer prevention was a main benefit of the HPV vaccine and sexual activity was a risk factor for HPV infection. Students often lacked knowledge about the vaccine's benefits for males and expressed some concerns about the safety and side effects of a vaccine perceived as new. Logistical barriers to vaccination included uncertainty over vaccination status and insurance coverage for the vaccine, and concerns about balancing the vaccine schedule with school obligations. Providers' vaccine recommendations were impacted by health system factors, including clinical infrastructure, processes for recommending and documenting vaccination, and office visit priorities. Suggested vaccination promotion strategies included improving the timing and messaging of outreach efforts on campus and bolstering clinical infrastructure.ConclusionsAlthough college may be an opportune time to reach young adults for HPV vaccination, obstacles including navigating parental influence and independent decision-making, lack of awareness of vaccination status, and numerous logistical and system-level barriers may impede vaccination during this time.

PurposeCancer survivors diagnosed at an early age remain at risk for cancer recurrence and other chronic diseases. This study assessed engagement in surveillance for recurrence, cancer screening, and other recommended preventive health services among breast and colorectal cancer survivors with early-onset disease (≤ 50 years) who were diagnosed in California.MethodsBreast and colorectal cancer survivors diagnosed with early-onset cancer between 1999 and 2009 were identified through the California Cancer Registry, the state-based cancer registry, and surveyed. Multivariable regression analyses were used to assess correlates of receipt of cancer surveillance, cancer screening, and other preventive health services.ResultsOf the 497 survivors that were invited to participate in the study, 156 completed the survey for a response rate of 31%. The sample was 50 years of age on average (range 32-69 years) with a mean time since diagnosis of 9 years. The majority of the sample (71%) was a racial/ethnic minority (24% Latino, 15% African American, 29% Asian). Overall, 80% received appropriate surveillance for recurrence, and 72% received recommended screening for early detection of other cancers (breast, cervical, colorectal). Increasing age was associated with lower likelihood of early detection screening (adjusted odds ratio (aOR) 0.28, 95% confidence interval (CI) 0.11-0.69), and higher income was associated with a greater likelihood (aOR 4.89, 95% CI 1.62-14.81). Screening rates were highest for blood pressure (96%), cholesterol (86%), and diabetes (81%), followed by dental visits (64%) and flu vaccination (35%). Greater use of recommended preventive health services was associated with increasing age, female sex, higher education level, and having health insurance.ConclusionsAlthough the majority of survivors received appropriate surveillance for recurrence, engagement in other preventive health services varied substantially.Implications for cancer survivorsEfforts are needed to address gaps in the use of recommended cancer screening and preventive health services among cancer survivors, particularly survivors with early-onset disease who may be at increased risk for additional cancers and common chronic conditions over their lifetime.

Hispanics represent the largest and one of the fastest growing minority populations in the U.S. and have lower survival from colorectal cancer (CRC) than non-Hispanic Whites (NHW). We aimed to examine screening modalities, predictors, and regional disparities among Hispanics and NHW in the U.S. by conducting a cross-sectional analysis of Hispanic participants age 50 to 75 from the 2016 Behavioral Risk Factor Surveillance System (BRFSS) survey. The primary outcome was self-reported CRC screening status. We used the Rao-Scott Chi-square test to compare screening rates and modalities in NHWs and Hispanics. We also used univariable and multivariable logistic regression to determine predictors of screening among Hispanics and calculated Hispanic-NHW screening rate differences for each U.S. state/territory as a measure of regional screening disparities. The screening rate was 53.4% for Hispanics (N = 12,395), compared to 70.4% for NHWs (N = 186,331) (p

OBJECTIVE: To compare the knowledge, beliefs, and practices regarding HPV vaccination among mothers of vaccine-eligible girls in Mexico and the USA. METHODS: Similar samples of Mexican mothers with vaccine-eligible daughters were surveyed at two clinics in Cuernavaca, Morelos, from July to October 2012 (n = 200) and at two clinics in Oxnard, California, from August to November 2013 (n = 200). RESULTS: Although mothers in the USA had less knowledge and more negative attitudes toward the vaccine than their counterparts in Mexico, vaccine uptake rates were higher in the USA (49% vs. 40%). US mothers were more likely to have discussed and been offered the HPV vaccine by a clinician than mothers in Mexico. In multivariate analyses, having been offered the HPV vaccine was the most important predictor of vaccine uptake. CONCLUSIONS: Our results suggest that healthcare access or other system, clinic, or provider factors are the main drivers of vaccine receipt in this binational sample of Mexican mothers. Interventions and programs that encourage clinicians to offer the HPV vaccine should be developed to increase vaccine uptake in both countries.

BackgroundHigh-cost patients are a frequent focus of improvement projects based on primary care and other settings. Efforts to characterize high-cost, high-need patients are needed to inform care planning, but such efforts often rely on a priori assumptions, masking underlying complexities of a heterogenous population.ObjectiveTo define recognizable subgroups of patients among high-cost adults based on clinical conditions, and describe their survival and future spending.DesignRetrospective observational cohort study.ParticipantsWithin a large integrated delivery system with 2.7 million adult members, we selected the top 1% of continuously enrolled adults with respect to total healthcare expenditures during 2010.Main measuresWe used latent class analysis to identify clusters of alike patients based on 53 hierarchical condition categories. Prognosis as measured by healthcare spending and survival was assessed through 2014 for the resulting classes of patients.ResultsAmong 21,183 high-cost adults, seven clinically distinctive subgroups of patients emerged. Classes included end-stage renal disease (12% of high-cost population), cardiopulmonary conditions (17%), diabetes with multiple comorbidities (8%), acute illness superimposed on chronic conditions (11%), conditions requiring highly specialized care (14%), neurologic and catastrophic conditions (5%), and patients with few comorbidities (the largest class, 33%). Over 4 years of follow-up, 6566 (31%) patients died, and survival in the classes ranged from 43 to 88%. Spending regressed to the mean in all classes except the ESRD and diabetes with multiple comorbidities groups.ConclusionsData-driven characterization of high-cost adults yielded clinically intuitive classes that were associated with survival and reflected markedly different healthcare needs. Relatively few high-cost patients remain persistently high cost over 4 years. Our results suggest that high-cost patients, while not a monolithic group, can be segmented into few subgroups. These subgroups may be the focus of future work to understand appropriateness of care and design interventions accordingly.

ObjectiveTo operationalize constructs from each of the Consolidated Framework for Implementation Research domains and to present psychometric properties within the context of evidence-based approaches for promoting colorectal cancer screening in federally qualified health centers (FQHCs).MethodsData were collected from FQHC clinics across seven states. A web-based Staff Survey and a Clinic Characteristics Survey were completed by staff and leaders (n = 277) from 59 FQHCs.ResultsInternal reliability of scales was adequate ranging from 0.62 for compatibility to 0.88 for other personal attributes (openness). Intraclass correlations for the scales indicated that 2.4 percent to 20.9 percent of the variance in scale scores occurs within clinics. Discriminant validity was adequate at the clinic level, with all correlations less than 0.75. Convergent validity was more difficult to assess given lack of hypothesized associations between factors expected to predict implementation.ConclusionsOur results move the field forward by describing initial psychometric properties of constructs across CFIR domains.

PurposeTo assess weight status, physical activity, and dietary behaviors in an ethnically-diverse sample of breast and colorectal cancer survivors with early onset disease (≤ 50 years).MethodsBreast and colorectal cancer survivors, diagnosed between 1999 and 2009 with early-stage cancer diagnosed by 50 years of age, were identified through a population-based cancer registry and surveyed. Descriptive and regression analyses were conducted to characterize the sample and identify correlates of lifestyle behaviors.FindingsThe majority of participants (n = 156) were female (83%), insured (84%), and racial/ethnic minorities (29% Asian, 24% Latino, 15% African American). Participants' mean age at response was 50 years and mean time since diagnosis was 9 years. Over half of survivors were overweight or obese. Few participants reported engaging in regular physical activity (31%) and adhering to minimum guidelines for fruit and vegetable consumption (32%). A substantial proportion of survivors consumed fast food in the past week (75%) and nearly half (48%) reported daily consumption of sugar-sweetened beverages. Lower income was associated with inadequate fruit and vegetable intake. Fast food and sugar-sweetened beverage consumption was significantly higher among racial/ethnic minority survivors compared to non-Latino whites.ConclusionsHigh prevalence of overweight and suboptimal adherence to recommended nutrition and physical activity behaviors were observed among cancer survivors with early onset disease. Cancer survivors diagnosed at a young age may benefit from targeted interventions to address overweight and suboptimal nutrition and physical activity.

Behavioral and mental health risk factors are prevalent among primary care patients and contribute substantially to premature morbidity and mortality and increased health care utilization and costs. Although prior studies have found most adults screen positive for multiple risk factors, limited research has attempted to identify factors that most commonly co-occur, which may guide future interventions. The purpose of this study was to identify subgroups of primary care patients with co-occurring risk factors and to examine sociodemographic characteristics associated with these subgroups. We assessed 12 behavioral health risk factors in a sample of adults (n=1628) receiving care from nine primary care practices across six U.S. states in 2013. Using latent class analysis, we identified four distinct patient subgroups: a 'Mental Health Risk' class (prevalence=14%; low physical activity, high stress, depressive symptoms, anxiety, and sleepiness), a 'Substance Use Risk' class (29%; highest tobacco, drug, alcohol use), a 'Dietary Risk' class (29%; high BMI, poor diet), and a 'Lower Risk' class (27%). Compared to the Lower Risk class, patients in the Mental Health Risk class were younger and less likely to be Latino/Hispanic, married, college educated, or employed. Patients in the Substance Use class tended to be younger, male, African American, unmarried, and less educated. African Americans were over 7 times more likely to be in the Dietary Risk versus Lower Risk class (OR 7.7, 95% CI 4.0-14.8). Given the heavy burden of behavioral health issues in primary care, efficiently addressing co-occurring risk factors in this setting is critical.

ObjectiveThis study examined patient-, care team- and clinic-level factors associated with human papillomavirus (HPV) vaccine initiation and completion.MethodsHPV vaccine initiation and completion rates among adolescents aged 9-18years were assessed using administrative data (n=38,277) from a large federally qualified health center serving predominantly Latino patients. Four clinics with particularly high and low adolescent HPV vaccine uptake were selected for in-depth case study analyses. Semi-structured interviews with clinic leaders, providers, and support staff in these clinics (n=36) examined multilevel factors perceived as affecting vaccine initiation and completion.ResultsOn average, less than half (45%) of patients had initiated the HPV vaccine; of these, 52% of patients completed all recommended doses. Vaccine uptake varied significantly across clinics but was higher among patients seen by providers specializing in pediatrics. Qualitative findings confirmed the importance of provider communication strategies but indicated that other health care team structures and processes also play an important role in vaccine uptake. Care team members in higher performing clinics were more likely to describe vaccination as a team effort rather than solely the provider's responsibility. Support staff in higher performing clinics also spent more time reviewing patient preventive care needs and preparing patients for the provider encounter. Clinic-level factors such as performance management systems and the use of immunization champions were described as important for developing an organizational climate supportive of vaccination. Tracking and reminder systems were described as important but insufficient for ensuring vaccine uptake in the absence of other supports.ConclusionsEfforts to improve HPV initiation and completion could benefit from additional attention to factors at the health care team and clinic levels. Interventions that target factors at multiple levels of influence are most likely to achieve higher vaccination rates. Quality monitoring programs may influence clinic investment in improving vaccination rates.

Many professional organizations recommend skin self-examination (SSE) as a tool for early detection of malignancy among melanoma survivors, a growing population that is at increased risk for new or recurrent melanoma. This study examined the frequency and correlates of SSE use among melanoma survivors. Additionally, we assessed skin exam use among children of survivors, who are at elevated lifetime risk for the disease. The California Cancer Registry was used to identify melanoma survivors, who were contacted, screened for eligibility, and invited to participate in a survey. The survey, administered by mail, web, or telephone, assessed a broad range of topics related to melanoma prevention in high-risk families. The present study focuses on skin examination practices of survivors and their children and potential correlates of these practices. Among a sample of 316 melanoma survivors, fewer than one in five participants performed monthly skin self-exams, a lower rate than that observed in previous studies. Although greater family history of melanoma, use of skin protection strategies, and the perceived severity of melanom were associated with more frequent use of skin self-exams, these relationships disappeared in adjusted analyses. Participants reported unexpectedly frequent use of skin examinations for their children despite the lack of professional guidelines for this practice. Interventions are needed to improve skin self-examination practices among melanoma survivors and to counsel parents about optimal melanoma prevention strategies for their children.

Background: There are long-standing black-white disparities in colorectal cancer incidence and outcomes in the United States. Incidence and stage at diagnosis reflect the impact of national efforts directed at colorectal cancer prevention and control. We aimed to evaluate trends in black-white disparities in both indicators over four decades to inform the future direction of prevention and control efforts.Methods: We used Surveillance, Epidemiology, & End Results (SEER) data to identify whites and blacks with histologically confirmed colorectal cancer from January 1, 1975 through December 31, 2012. We calculated the age-adjusted incidence and the proportion of cases presenting in late stage by race and year. We then calculated the annual percentage change (APC) and average APC for each indicator by race, examined changes in indicators over time, and calculated the incidence disparity for each year.Results: There were 440,144 colorectal cancer cases from 1975 to 2012. The overall incidence decreased by 1.35% and 0.46% per year for whites and blacks, respectively. Although the disparity in incidence declined from 2004 to 2012 (APC = -3.88%; P = 0.01), incidence remained higher in blacks in 2012. Late-stage disease declined by 0.27% and 0.45% per year in whites and blacks, respectively. The proportion of late-stage cases became statistically similar in whites and blacks in 2010 (56.60% vs. 56.96%; P = 0.17).Conclusions: Black-white disparities in colorectal cancer incidence and stage at presentation have decreased over time.Impact: Our findings reflect the positive impact of efforts to improve colorectal cancer disparities and emphasize the need for interventions to further reduce the incidence gap.

BackgroundSchool climate is an integral part of a comprehensive approach to improving the well-being of students; however, little is known about the relationships between its different domains and measures. We examined the relationships between student, staff, and administrative measures of school climate to understand the extent to which they were related to each other and student outcomes.MethodsThe sample included 33,572 secondary school students from 121 schools in Los Angeles County during the 2014-2015 academic year. A multilevel regression model was constructed to examine the association between the domains and measures of school climate and 5 outcomes of student well-being: depressive symptoms or suicidal ideation, tobacco use, alcohol use, marijuana use, and grades.ResultsStudent, staff, and administrative measures of school climate were weakly correlated. Strong associations were found between student outcomes and student reports of engagement and safety, while school staff reports and administrative measures of school climate showed limited associations with student outcomes.ConclusionsAs schools seek to measure and implement interventions aimed at improving school climate, consideration should be given to grounding these efforts in a multidimensional conceptualization of climate that values student perspectives and includes elements of both engagement and safety.

Contact with the justice system can lead to a range of poor health and social outcomes. While persons of color are disproportionately represented in both the juvenile and criminal justice systems, reasons for these patters remain unclear. This study sought to examine the extent and sources of differences in arrests during adolescence and young adulthood among blacks, whites, and Hispanics in the USA. Multilevel cross-sectional logistic regression analyses were conducted using data from waves I and IV of the National Longitudinal Study of Adolescent to Adult Health (n = 12,752 respondents). Results showed significantly higher likelihood of having ever been arrested among blacks, when compared to whites, even after controlling for a range of delinquent behaviors (odds ratio = 1.58, 95 % confidence interval = 1.27, 1.95). These black-white disparities were no longer present after accounting for racial composition of the neighborhood, supporting the growing body of research demonstrating the importance of contextual variables in driving disproportionate minority contact with the justice system.

BackgroundSocial media offer an unprecedented opportunity to explore how people talk about health care at a very large scale. Numerous studies have shown the importance of websites with user forums for people seeking information related to health. Parents turn to some of these sites, colloquially referred to as "mommy blogs," to share concerns about children's health care, including vaccination. Although substantial work has considered the role of social media, particularly Twitter, in discussions of vaccination and other health care-related issues, there has been little work on describing the underlying structure of these discussions and the role of persuasive storytelling, particularly on sites with no limits on post length. Understanding the role of persuasive storytelling at Internet scale provides useful insight into how people discuss vaccinations, including exemption-seeking behavior, which has been tied to a recent diminution of herd immunity in some communities.ObjectiveTo develop an automated and scalable machine-learning method for story aggregation on social media sites dedicated to discussions of parenting. We wanted to discover the aggregate narrative frameworks to which individuals, through their exchange of experiences and commentary, contribute over time in a particular topic domain. We also wanted to characterize temporal trends in these narrative frameworks on the sites over the study period.MethodsTo ensure that our data capture long-term discussions and not short-term reactions to recent events, we developed a dataset of 1.99 million posts contributed by 40,056 users and viewed 20.12 million times indexed from 2 parenting sites over a period of 105 months. Using probabilistic methods, we determined the topics of discussion on these parenting sites. We developed a generative statistical-mechanical narrative model to automatically extract the underlying stories and story fragments from millions of posts. We aggregated the stories into an overarching narrative framework graph. In our model, stories were represented as network graphs with actants as nodes and their various relationships as edges. We estimated the latent stories circulating on these sites by modeling the posts as a sampling of the hidden narrative framework graph. Temporal trends were examined based on monthly user-poststatistics.ResultsWe discovered that discussions of exemption from vaccination requirements are highly represented. We found a strong narrative framework related to exemption seeking and a culture of distrust of government and medical institutions. Various posts reinforced part of the narrative framework graph in which parents, medical professionals, and religious institutions emerged as key nodes, and exemption seeking emerged as an important edge. In the aggregate story, parents used religion or belief to acquire exemptions to protect their children from vaccines that are required by schools or government institutions, but (allegedly) cause adverse reactions such as autism, pain, compromised immunity, and even death. Although parents joined and left the discussion forums over time, discussions and stories about exemptions were persistent and robust to these membership changes.ConclusionsAnalyzing parent forums about health care using an automated analytic approach, such as the one presented here, allows the detection of widespread narrative frameworks that structure and inform discussions. In most vaccination stories from the sites we analyzed, it is taken for granted that vaccines and not vaccine preventable diseases (VPDs) pose a threat to children. Because vaccines are seen as a threat, parents focus on sharing successful strategies for avoiding them, with exemption being the foremost among these strategies. When new parents join such sites, they may be exposed to this endemic narrative framework in the threads they read and to which they contribute, which may influence their health care decision making.

Patient-centered health risk assessments (HRAs) that screen for unhealthy behaviors, prioritize concerns, and provide feedback may improve counseling, goal setting, and health. To evaluate the effectiveness of routinely administering a patient-centered HRA, My Own Health Report, for diet, exercise, smoking, alcohol, drug use, stress, depression, anxiety, and sleep, 18 primary care practices were randomized to ask patients to complete My Own Health Report (MOHR) before an office visit (intervention) or continue usual care (control). Intervention practice patients were more likely than control practice patients to be asked about each of eight risks (range of differences 5.3-15.8 %, p

While previous studies have described psychosocial and environmental factors that contribute to healthy eating, much remains unknown about the interactions between them. We assessed the relationship between the perceived food environment, self-efficacy and fruit and vegetable consumption, using data from a sample of racially diverse, low-income adult clientele of five public health centers in Los Angeles County (n = 1503). We constructed a negative binomial regression model to examine the association between perceived food environment and the number of fruits and vegetables consumed. For every one point increase on the perceived food environment scale, individuals ate about 5% more fruits and vegetables (95% CI 1.007, 1.089), controlling for other covariates. Self-efficacy was shown to be a significant mediator (mediated effect = 0.010; 95% CI 0.002, 0.020), accounting for 22.9% of the effect. Efforts to increase access to healthy options may not only improve eating behaviors, but also influence individuals' beliefs that they can eat healthfully.

The literature suggests that Korean Americans underutilize health services. Cultural factors and language barriers appear to influence this pattern of low utilization but studies on the relationships among length of stay in the US, English use and proficiency, and utilization of health services among Korean Americans have yielded inconsistent results. This study examines whether English language use and proficiency plays a mediating role in the relationships between length of stay in the US and health insurance coverage, access to and use of care. Structural equation modeling was used for mediation analysis with multiple dependent variables among Korean Americans (N = 555) using baseline data from a large trial designed to increase Hepatitis B testing. The results show 36% of the total effect of proportion of lifetime in the US on having health insurance was significantly mediated by English use and proficiency (indirect effect = 0.166, SE = 0.07, p

BackgroundEthnic minorities, especially African Americans and Latinos, bear a disproportionate burden of colorectal cancer (CRC), as reflected in incidence, cancer stage, and mortality statistics. In all ethnic groups, first-degree relatives (FDRs) of CRC cases are at an elevated disease risk. However, underuse of CRC screening persists and is particularly evident among minority groups. The current study tested a stepped intervention to increase CRC screening among an ethnically diverse sample of FDRs of CRC cases.MethodsA statewide cancer registry was used to recruit CRC cases and through them their FDRs. Relatives who were not current on CRC screening were randomized to intervention or usual-care control arms. The stepped intervention consisted of ethnically targeted and individually tailored print materials followed by telephone counseling for those unscreened at 6 months.ResultsThe study sample of 1280 individuals consisted of 403 Latino, 284 African American, 242 Asian, and 351 white FDRs. Statistically significant effects were observed for the cumulative print plus telephone intervention at 12 months (26% in the intervention vs 18% in the control group) and the print intervention alone at 6 months (15% in the intervention vs 10% in the control group). The effect of the print intervention alone versus the cumulative interventions was not statistically significantly different. Stratified analyses indicated that the intervention was effective among white, Latino, and Asian individuals, but not among African-Americans.ConclusionsOverall, the intervention was effective in increasing screening rates. Oversampling racial/ethnic minorities allowed for the examination of effects within subgroups, revealing no effect among African American individuals. This finding illustrates the importance of including sufficient numbers of participants from diverse ethnic subgroups in intervention research to enable such stratified analyses.

BackgroundIn the United States, Korean immigrants experience a disproportionately high burden of chronic hepatitis B (HBV) viral infection and associated liver cancer compared with the general population. However, despite clear clinical guidelines, HBV serologic testing among Koreans remains persistently suboptimal.MethodsWe conducted a cluster-randomized trial to evaluate a church-based small group intervention to improve HBV testing among Koreans in Los Angeles. Fifty-two Korean churches, stratified by size (small, medium, large) and location (Koreatown versus other), were randomized to intervention or control conditions. Intervention church participants attended a single-session small-group discussion on liver cancer and HBV testing, and control church participants attended a similar session on physical activity and nutrition. Outcome data consisted of self-reported HBV testing obtained via 6-month telephone follow-up interviews.ResultsWe recruited 1,123 individuals, 18 to 64 years of age, across the 52 churches. Ninety-two percent of the sample attended the assigned intervention session and 86% completed the 6-month follow-up. Sample characteristics included were as follows: mean age 46 years, 65% female, 97% born in Korea, 69% completed some college, and 43% insured. In an intent-to-treat analysis, the intervention produced a statistically significant effect (OR = 4.9, P < 0.001), with 19% of intervention and 6% of control group participants reporting a HBV test.ConclusionOur intervention was successful in achieving a large and robust effect in a population at high risk of HBV infection and sequelae.ImpactThe intervention was fairly resource efficient and thus has high potential for replication in other high-risk Asian groups.

BackgroundEnhancing the capability of community health centers to implement best practices (BPs) may mitigate health disparities. This study investigated the association of practice adaptive reserve (PAR) with the implementation of patient-centered medical home (PCMH) colorectal cancer (CRC) screening BPs at community health center clinics in 7 states.MethodsA convenience sample of clinic staff participated in a self-administered, online survey. Eight PCMH CRC screening BPs were scored as a composite ranging from 0 to 32. The PAR composite score was scaled from 0 to 1 and then categorized into 3 levels. Multilevel analyses examined the relation between PAR and self-reported implementation of PCMH BPs.ResultsThere were 296 respondents, and 59% reported 6 or more PCMH BPs at their clinics. The mean PAR score was 0.66 (standard deviation, 0.18), and the PCMH BP mean scores were significantly higher for respondents who reported higher clinic PAR categories. In comparison with the lowest PAR level, adjusted PCMH BP means were 25.0% higher at the middle PAR level (difference, 3.2; standard error, 1.3; t = 2.44; P = .015) and 63.2% higher at the highest PAR level (difference, 8.0; standard error, 1.9; t = 4.86; P

A multi-site study was conducted to assess HPV vaccine initiation and correlates of initiation among Latina adolescents. The study was a collaboration of the CDC/NCI-funded Cancer Prevention and Control Research Network. Data were collected in 2009 from caregivers of Latina adolescents recruited from Los Angeles Country (n = 274), Washington State (Yakima Valley region; n = 90), and Texas (Houston, n = 38; Lower Rio Grande Valley, n = 42). A set of 24 survey items assessed use of the HPV vaccine and awareness, attitudes and barriers to vaccination. Moderate levels of vaccine awareness among caregivers and low uptake of the vaccine (26-37%) among girls were observed. Attitudinal barriers such as concerns about negative effects of the vaccine on daughter's sexual behavior, fertility, and future health were infrequently endorsed. Efforts to understand regional similarities and differences may help inform interventions.

BackgroundFirst-degree relatives of melanoma survivors have a substantially higher lifetime risk for melanoma than individuals with no family history. Exposure to ultraviolet radiation (UVR) is the primary modifiable risk factor for the disease. Reducing UV exposure through sun protection may be particularly important for children with a parental history of melanoma. Nonetheless, limited prior research has investigated sun protection practices and sun exposure among these children.MethodsThe California Cancer Registry was used to identify melanoma survivors eligible to participate in a survey to assess their children's sun protection practices and sun exposure. The survey was administered by mail, telephone, or web to Latino and non-Latino white melanoma survivors with at least one child (0-17 years; N = 324).ResultsSun exposure was high and the rate of sunburn was equivalent to or higher than estimates from average-risk populations. Use of sun protection was suboptimal. Latino children were less likely to wear sunscreen and hats and more likely to wear sunglasses, although these differences disappeared in adjusted analyses. Increasing age of the child was associated with lower sun protection and higher risk for sunburn, whereas higher objective risk for melanoma predicted improved sun protection and a higher risk for sunburns. Perception of high barriers to sun protection was the strongest modifiable correlate of sun protection.ConclusionsInterventions to improve sun protection and reduce sun exposure and sunburns in high-risk children are needed.ImpactIntervening in high-risk populations may help reduce the burden of melanoma in the United States.
