A scoping review of racial, ethnic, socioeconomic, and geographic disparities in the outcomes of older adults with cancer.

INTRODUCTION: Cancer health disparities are widespread. Nevertheless, the disparities in outcomes among diverse survivors of cancer ages 65 years and older ("older") have not been systematically evaluated. METHODS: We conducted a scoping review of original research articles published between January 2016 and September 2023 and indexed in Medline (Ovid), Embase, Scopus, and CINAHL databases. We included studies evaluating racial, ethnic, socioeconomic disadvantaged, geographic, sexual and gender, and/or persons with disabilities disparities in treatment, survivorship, and mortality among older survivors of cancer. We excluded studies with no a priori aims related to a health disparity, review articles, conference proceedings, meeting abstracts, studies with unclear methodologies, and articles in which the disparity group was examined only as an analytic covariate. Two reviewers independently extracted data following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis reporting guidelines. RESULTS: After searching and removing duplicates, 2573 unique citations remained and after screening 59 articles met the inclusion criteria. Many investigated more than one health disparity, and most focused on racial and ethnic (n = 44) or socioeconomic (n = 25) disparities; only 10 studies described geographic disparities, and none evaluated disparities in persons with disabilities or due to sexual and gender identity. Research investigating disparities in outcomes among diverse older survivors of cancer is increasing gradually-68% of eligible articles were published between 2020 and 2023. Most studies focused on the treatment phase of care (n = 28) and mortality (n = 26), with 16 examined disparities in survivorship, symptoms, or quality of life. Most research was descriptive and lacked analyses of potential underlying mechanisms contributing to the reported disparities. CONCLUSION: Little research has evaluated the effect of strategies to reduce health disparities among older patients with cancer. This lack of evidence perpetuates cancer inequities and leaves the cancer care system ill equipped to address the unique needs of the rapidly growing and increasingly diverse older adult cancer population.

The disproportionate burden of Alzheimer's disease and related dementias (ADRD) in diverse older adults diagnosed with cancer.

INTRODUCTION: Older adults living with Alzheimer's disease and related dementias (ADRD) who are then diagnosed with cancer are an understudied population. While the role of cognitive impairment during and after cancer treatment have been well-studied, less is understood about patients who are living with ADRD and then develop cancer. The purpose of this study is to contribute evidence about our understanding of this vulnerable population. MATERIALS AND METHODS: This was a retrospective cohort study of a linked, representative family of databases of cancer registries and Medicare administrative claims that make up the SEER-Medicare database. Older adults ages 68 and older with a first primary cancer type: breast, cervical, colorectal, lung, oral, or prostate were eligible for inclusion (N = 337,932). Prevalence estimates of ADRD across cancer types and a 5% non-cancer comparison sample were compared by patient factors. RESULTS: The overall prevalence of patients who had an ADRD diagnosis anytime in the three years prior to their cancer diagnosis was 5.6%. Patients with ADRD were more likely to be female, older (over age 75), a racial/ethnic minority, single, with multiple chronic conditions, and a tumor diagnosed early (stage I) or were unstaged. Black patients with colorectal and oral cancer had the highest and second highest prevalence of ADRD compared to White patients (13.46% vs 7.95% and 12.64% vs 7.82% respectively, p < .0001). We observed the highest prevalence of ADRD among Black patients for breast (11.85%), cervical (11.98%), lung (8.41%), prostate (4.83), and the 5% sample (9.50%, p > .0001). DISCUSSION: The higher prevalence of ADRD among Black and Latine older adults with cancer not only aligns with the trend observed in our non-cancer comparison sample, but also, these findings demonstrate the compounded risk experienced by minoritized older adults over the life course. The greater than expected prevalence of patients with ADRD who go on to develop cancer demonstrates better assessment of cognition is urgently needed. Accurate identification of these vulnerable populations is critical to improve assessment, care coordination, and address inequities in screening and treatment planning.

Toward alert triage: scalable qualitative coding framework for analyzing alert notes from the Telehealth Intervention Program for Seniors (TIPS).

Objective: Combined with mobile monitoring devices, telehealth generates overwhelming data, which could cause clinician burnout and overlooking critical patient status. Developing novel and efficient ways to correctly triage such data will be critical to a successful telehealth adoption. We aim to develop an automated classification framework of existing nurses' notes for each alert that will serve as a training dataset for a future alert triage system for telehealth programs. Materials and Methods: We analyzed and developed a coding framework and a regular expression-based keyword match approach based on the information of 24 931 alert notes from a community-based telehealth program. We evaluated our automated alert triaging model for its scalability on a stratified sampling of 800 alert notes for precision and recall analysis. Results: We found 22 717 out of 24 579 alert notes (92%) belonging to at least one of the 17 codes. The evaluation of the automated alert note analysis using the regular expression-based information extraction approach resulted in an average precision of 0.86 (SD = 0.13) and recall 0.90 (SD = 0.13). Discussion: The high-performance results show the feasibility and the scalability potential of this approach in community-based, low-income older adult telehealth settings. The resulting coded alert notes can be combined with participants' health monitoring results to generate predictive models and to triage false alerts. The findings build steps toward developing an automated alert triaging model to improve the identification of alert types in remote health monitoring and telehealth systems.

Practical Assessment and Management of Vulnerabilities in Older Patients Receiving Systemic Cancer Therapy: ASCO Guideline Update.

PURPOSE: To update the ASCO guideline (2018) on the practical assessment and management of age-associated vulnerabilities in older patients undergoing systemic cancer therapy. METHODS: An Expert Panel conducted a systematic review to identify relevant randomized clinical trials (RCTs), systematic reviews, and meta-analyses from January 2016 to December 2022. RESULTS: A total of 26 publications met eligibility criteria and form the evidentiary basis for the update. RECOMMENDATIONS: The Expert Panel reiterates its overarching recommendation from the prior guideline that geriatric assessment (GA), including all essential domains, should be used to identify vulnerabilities or impairments that are not routinely captured in oncology assessments for all patients over 65 years old with cancer. Based on recently published RCTs demonstrating significantly improved clinical outcomes, all older adults with cancer (65+ years old) receiving systemic therapy with GA-identified deficits should have GA-guided management (GAM) included in their care plan. GAM includes using GA findings to inform cancer treatment decision-making as well as to address impairments through appropriate interventions, counseling, and/or referrals. A GA should include high priority aging-related domains known to be associated with outcomes in older adults with cancer: physical and cognitive function, emotional health, comorbid conditions, polypharmacy, nutrition, and social support. Clinical adaptation of the GA based on patient population, resources, and time is appropriate.The Panel recommends the Practical Geriatric Assessment as one option for this purpose (https://old-prod.asco.org/sites/new-www.asco.org/files/content-files/practice-patients/documents/2023-PGA-Final.pdf; https://youtu.be/jnaQIjOz2Dw; https://youtu.be/nZXtwaGh0Z0).Additional information is available at www.asco.org/supportive-care-guidelines.

The influences of faith on illness representations and coping procedures of mental and cognitive health among aging Arab refugees: a qualitative study.

Introduction: Refugees experience higher rates of mental illness such as depression and post-traumatic stress disorder (PTSD) which are documented risk factors for dementia. Faith and spiritual practices have been shown to play a significant role in patients' understanding and coping with illness, however, this field of study among refugee populations remains lacking. This study aims to address this literature gap by examining the role of faith on mental health and cognitive health among Arab refugees resettled in Arab and Western countries. Materials and methods: A total of 61 Arab refugees were recruited through ethnic community-based organizations in San Diego, California, United States (N = 29) and Amman, Jordan (N = 32). Participants were interviewed through in-depth, semi-structured interviews or focus groups. Interviews and focus groups were transcribed, translated, and coded using inductive thematic analysis and organized based on Leventhal's Self-Regulation Model. Results: Faith and spiritual practices significantly impact participants' illness perceptions and coping procedures regardless of resettlement country or gender. Several themes emerged: (1) participants believe in the interdependent relationship between mental and cognitive health. (2) There is a self-awareness of the impact of the refugee experience and trauma on participants' mental health problems, leading to a belief of increased personal risk for developing dementia. (3) Spiritual fatalism (belief that events are predetermined by God, fate, or destiny) greatly informs these perceptions of mental and cognitive health. (4) Participants acknowledge that practicing faith improves their mental and cognitive health, and many read scripture to prevent dementia. (5) Finally, spiritual gratitude and trust are important coping procedures that build resilience among participants. Conclusions: Faith and spirituality play an important role in shaping Arab refugees' illness representations and coping procedures of mental and cognitive health. Holistic public health and clinical interventions tailored to the spiritual needs of aging refugees and incorporating religion in prevention strategies are increasingly needed to improve the brain health and wellbeing of refugees.

Digital health in geriatric oncology: A Young International Society of Geriatric Oncology review.

The integration of digital health technologies in geriatric oncology has the potential to enhance patient care and self-management. This review article discusses the applications of these technologies, including teleassessment, telemonitoring, and teleintervention, within geriatric oncology, and evaluates their potential to improve cancer care and patient outcomes. We also review challenges to the implementation of digital health technologies among populations of older patients with cancer. The article provides a perspective for clinicians, researchers, policymakers, and patients on the integration and utilisation of digital health technologies in current geriatric oncology practice.

Experiences and Perceptions of Distinct Telehealth Delivery Models for Remote Patient Monitoring among Older Adults in the Community.

Three major telehealth delivery models-home-based, community-based, and telephone-based-have been adopted to enable remote patient monitoring of older adults to improve patient experience and reduce healthcare costs. Even though prior work has evaluated each of these delivery models, we know less about the perceptions and user experiences across these telehealth delivery models for older adults. In the present work, we addressed this research gap by interviewing 16 older adults who had experience using all these telehealth delivery models. We found that the community-based telehealth model with in-person interactions was perceived as the most preferred and useful program, followed by home-based and telephone-based models. Persistent needs reported by participants included ease of access to their historical physiological data, useful educational information for health self-management, and additional health status tracking. Our findings will inform the design and deployment of telehealth technology for vulnerable aging populations.

Social Justice and Equity: Why Older Adults With Cancer Belong-A Life Course Perspective.

The population of older adults with cancer in the United States is rapidly increasing, which will have a substantial impact on the oncology and public health workforces across the cancer continuum, from prevention to end of life. Unfortunately, inequities in existing social structures that cause increased psychosocial stressors have led to disparities in the incidence of cancer and the morbidity and mortality of cancer for individuals from marginalized backgrounds. It is imperative that older adults, especially those from historically marginalized backgrounds, be adequately represented in all stages of cancer research to address health inequities. Continued efforts and progress toward achieving social justice and health equity require a deeper commitment to and better understanding of the impact of social determinants of health within the cancer domain. Undoubtedly, a more holistic and integrated view that extends beyond the biologic and genetic factors of health must be adopted for health entities to recognize the critical role of environmental, behavioral, and social determinants in cancer health disparities. Against this backdrop, this paper uses a life course approach to present a multifactorial framework for understanding and addressing cancer disparities in an effort to advance social justice and health equity for racially and ethnically diverse older adults.

Association of Physician Referrals with Timely Cancer Care Using Tumor Registry and Claims Data.

More Americans are being screened for and more are surviving colorectal cancer due to advanced treatments and better quality of care; however, these benefits are not equitably distributed among diverse or older populations. Differential care delivery outcomes are driven by multiple factors, including access to timely treatment that comes from high-quality care coordination. Providers help ensure such coordinated care, which includes timely referrals to specialists. Variation in referrals between providers can also result in differences in treatment plans and outcomes. Patients who are more often referred between the same diagnosing and treating providers may benefit from more timely care compared to those who are not. Our objective is to examine patterns of referral, or patient-sharing networks (PSNs), and our outcome, treatment delay of 30-days (yes/no). We hypothesize that if a patient is in a PSN they will have lower odds of a 30-day treatment initiation delay. Our observational population-based analysis using the National Cancer Institute (NCI)-linked tumor registry and Medicare claims database includes records for 27,689 patients diagnosed with colorectal cancer from 2001 to 2013, and treated with either chemotherapy, radiotherapy, or surgery. We modeled the adjusted odds of a delay and found 17.04% of patients experienced a 30-day delay in initial treatment. Factors that increased odds of a delay were lack of membership in a PSN (adjusted odds ratio [AOR]: 2.20; 95% confidence interval [CI]: 1.71-2.84), racial/ethnic minority status, and having multiple comorbidities. Provider characteristics significantly associated with greater odds of a delay were if dyads were not in the same facility (AOR: 1.95; 95% CI: 1.81-2.10), if providers were different genders, most notably male (diagnosing) and female (treating) [AOR: 1.23; 95% CI: 1.08-1.40, p = 0.0015]. PSNs appear to be associated with reduced of a care delay. The associations observed in our study address the demand for developing multilevel interventions to improve the delivery and coordination of high-quality of care for older cancer patients.

Disparities in telemedicine during COVID-19.

BACKGROUND: Oncology rapidly shifted to telemedicine in response to the COVID-19 pandemic. Telemedicine can increase access to healthcare, but recent research has shown disparities exist with telemedicine use during the pandemic. This study evaluated health disparities associated with telemedicine uptake during the COVID-19 pandemic among cancer patients in a tertiary care academic medical center. METHODS: This retrospective cohort study evaluated telemedicine use among adult cancer patients who received outpatient medical oncology care within a tertiary care academic healthcare system between January and September 2020. We used multivariable mixed-effects logistic regression models to determine how telemedicine use varied by patient race/ethnicity, primary language, insurance status, and income level. We assessed geospatial links between zip-code level COVID-19 infection rates and telemedicine use. RESULTS: Among 29,421 patient encounters over the study period, 8,541 (29%) were delivered via telemedicine. Several groups of patients were less likely to use telemedicine, including Hispanic (adjusted odds ratio [aOR] 0.86, p = 0.03), Asian (aOR 0.79, p = 0.002), Spanish-speaking (aOR 0.71, p = 0.0006), low-income (aOR 0.67, p < 0.0001), and those with Medicaid (aOR 0.66, p < 0.0001). Lower rates of telemedicine use were found in zip codes with higher rates of COVID-19 infection. Each 10% increase in COVID-19 infection rates was associated with an 8.3% decrease in telemedicine use (p = 0.002). CONCLUSIONS: This study demonstrates racial/ethnic, language, and income-level disparities with telemedicine use, which ultimately led patients with the highest risk of COVID-19 infection to use telemedicine the least. Additional research to better understand actionable barriers will help improve telemedicine access among our underserved populations.

California's Health4All Kids Expansion And Health Insurance Coverage Among Low-Income Noncitizen Children.

More than one-third of US children receive coverage through Medicaid and the Children's Health Insurance Program (CHIP), but undocumented immigrant children are not eligible for public coverage in most states. California's May 2016 Health4All Kids coverage expansion allowed children with qualifying household incomes to enroll in Medi-Cal, California's Medicaid and CHIP program, regardless of their immigration status. We examined the effects of California's expansion on noncitizen children's uninsurance rates and sources of coverage, using data from the 2012-18 American Community Survey. California's expansion was associated with significant increases of about 9 and 12 percentage points in any coverage and public coverage, respectively. The estimated increase in any coverage translates to a 34 percent decline in the uninsurance rate relative to the preexpansion rate among noncitizen children (26 percent). Counties with an existing program to reduce children's uninsurance rates experienced an increase in coverage earlier than those without a program in effect before the statewide expansion.

Disparities in self-management outcomes by limited English proficiency among adults with heart disease.

There are significant disparities in cardiovascular health outcomes by limited English proficiency (LEP). Self-management plans (SMPs) are associated with better patient outcomes, however little is known about the association of LEP with having an SMP among adults with heart disease. This study examined this association using 2013-2016 California Health Interview Survey data. Among adults that received an SMP, we also examined whether they had a hard copy SMP (print or electronic vs. none), and whether they reported confidence in their ability to manage their heart disease. Our sample included a total of 9102 adults, including 1232 LEP and 7870 English proficient (EP) adults. LEP was associated with significantly lower odds of SMP receipt (Adjusted Odds Ratio [AOR] 0.46, 95% Confidence Interval [CI] 0.31 to 0.68). LEP and EP adults who received an SMP were similarly likely to have a hard copy SMP and report confidence in heart disease management. The finding that LEP adults were less likely than EP adults to receive an SMP may represent a missed opportunity to improve heart health outcomes for this group.

Predictors of Retention for Community-Based Telehealth Programs: A Study of the Telehealth Intervention Program for Seniors (TIPS).

Community-based telehealth programs (CTPs) allow patients to regularly monitor health at community-based facilities. Evidence from community-based telehealth programs is scarce. In this paper, we assess factors of retention-patients remaining active participants-in a CTP called the Telehealth Intervention Programs for Seniors (TIPS). We analyzed 5-years of data on social, demographic, and multiple chronic conditions among participants from 17 sites (N=1878). We modeled a stratified multivariable logistic regression to test the association between self-reported demographic factors, caregiver status, presence of multiple chronic conditions, and TIPS retention status by limited English proficient (LEP) status. Overall, 59.5% of participants (mean age: 75.8yrs, median 77yrs, SD 13.43) remained active. Significantly higher odds of retention were observed among LEP females, English-speaking diabetics, and English proficient (EP) participants without a caregiver. We discuss the impact of CTPs in the community, the role of caregiving, and recommendations for how to retain successfully recruited non-English speaking participants.

Mapping the online social network of cancer bloggers.

While social media has the ability to quickly disseminate information and reach large audiences, cancer blogs as a communication platform have not yet been well studied. A social network analysis was conducted on 89 active cancer blogs. Results demonstrated the overall cancer-blog-network was widely distributed and decentralized, with blogs clustered by cancer type, and that breast cancer blogs were the most significant and highly linked blogs. Efforts to disseminate cancer-related information may focus on identifying key breast cancer bloggers or linking key bloggers of various cancers to create a more interconnected network and expand its reach within this online community.

Culturally and Linguistically Appropriate Hospital Services Reduce Medicare Length of Stay.

Introduction: Almost 40% of the 63 million Americans who speak a language other than English have limited English proficiency (LEP). This communication barrier can result in poor quality care and potentially adverse health outcomes. Of particular interest is that the greatest proportion of LEP adults are aged >65 years and will face barriers and delays in accessing high-quality care. Age cohort variation of LEP burden has not been widely addressed. Culturally and linguistically appropriate hospital care delivery can mitigate these barriers. Methods: In order to test whether culturally competent services reduced length-of-stay (LOS), we linked organizational cultural competence surveys across two-states (CA+FL) for comparison across Medicare acute care LOS. Using the 2013 American Hospital Association Database, and Hospital Compare Data from CMS (N=184), we compared hospital structure with culturally and linguistically appropriate services related to improved care delivery for LEP populations and aging LEP populations. We utilized Kruskal-Wallis to test group differences and a negative binomial regression to model median LOS. All analyses were conducted using SAS 9.4 (Cary, NC). Results: Median LOS across all hospitals was 4.7 days (mean 5.7, standard deviation 6.3). Most hospitals were not-for-profit (46.7%), small (<150 beds, 54.4%), Joint Commission accredited (67.9%), and in urban areas. We found shorter median LOS when hospital units identified cultural or language needs at admission (Wald χ23.82, P=.0506). Hospitals' identification of these needs at discharge had no impact on LOS. Hospitals that accommodated patient cultural or ethnic dietary needs also reported lower median LOS (Wald χ2 12.93, P=.0003). Structurally, public hospitals, accredited hospitals, and hospitals that reported system membership were predictive of a lower median LOS. Discussion: Our findings demonstrate that patient outcomes are responsive to culturally and linguistically appropriate services. Further, our findings suggest understanding of culturally competent care in hospitals is lacking. A larger and multi-level sample across the United States could yield a greater understanding of the role of culturally and linguistically appropriate care for a rapidly growing population of diverse older adults.

Associations Between Nonclinical Services and Patient-Experience Outcomes in US Acute Care Hospitals.

BACKGROUND: Patient experience is an important measure of hospital quality and performance. Since the passage of the Affordable Care Act, patient experiences with their care encounters are embedded into the framework of payment incentives. However, drivers of patient experience in the context of the supportive, nonclinical, services that relate to patient care have not been as well understood. AIMS: To assess the role of organizational factors on patient experience. METHODS: This cross-sectional analysis integrates hospital patient-experience scores from Hospital Consumer Assessment of Healthcare Providers and Systems, and Centers for Medicaid and Medicare Service data from 2013 to 2015 (N = 3392). Based on hospitals with "top-box" responses, the aggregate proportion of hospital patients responding "always" on a Likert scale represented a top-box hospital. Domains were split at the mean for analysis (above average = 1). Multivariable logistic regression models for each domain were analyzed against hospital factors and services, including offering a patient education center, patient-enabling services, and language services. RESULTS: Most hospitals reported a full-time hospitalist (64.4%) and a patient education center (60.4%), while fewer provided enabling/support services (33.7%). In multivariable models, small and medium hospitals performed better compared to the largest hospitals (300+ beds; P < .0001). Structurally, medium and small hospitals reported significantly greater odds of top-box patient-experience versus large hospitals. Across all domains, only hospitals with patient education centers returned better performance (adjusted odds ratio: 1.27-1.64; P = .0002-.0166). DISCUSSION/CONCLUSION: Patient education centers provide relevant information at the point of service and may improve overall patient experience of care. Given the growing reliance on accountable care delivery models, opportunities to partner with community health education partners may be profitable.

Consumer Health Informatics Adoption among Underserved Populations: Thinking beyond the Digital Divide.

OBJECTIVES: Underserved populations can benefit from consumer health informatics (CHI) that promotes self-management at a lower cost. However, prior literature suggested that the digital divide and low motivation constituted barriers to CHI adoption. Despite increased Internet use, underserved populations continue to show slow CHI uptake. The aim of the paper is to revisit barriers and facilitators that may impact CHI adoption among underserved populations. METHODS: We surveyed the past five years of literature. We searched PubMed for articles published between 2012 and 2017 that describe empirical evaluations involving CHI use by underserved populations. We abstracted and summarized data about facilitators and barriers impacting CHI adoption. RESULTS: From 645 search results, after abstract and full-text screening, 13 publications met the inclusion criteria of identifying barriers to and facilitators of underserved populations' CHI adoption. Contrary to earlier literature, the studies suggested that the motivation to improve health literacy and adopt technology was high among studied populations. Beyond the digital divide, barriers included: low health and computer literacy, challenges in accepting the presented information, poor usability, and unclear content. Factors associated with increased use were: user needs for information, user-access mediated by a proxy person, and early user engagement in system design. CONCLUSIONS: While the digital divide remains a barrier, newer studies show that high motivation for CHI use exists. However, simply gaining access to technology is not sufficient to improve adoption unless CHI technology is tailored to address user needs. Future interventions should consider building larger empirical evidence on identifying CHI barriers and facilitators.

Sustained Hospital Performance on Hospital Consumer Assessment of Healthcare Providers and Systems Survey Measures: What Are the Determinants?

EXECUTIVE SUMMARY: This study examines hospital characteristics associated with sustained superior performance on Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) measures. We classified hospitals as sustainers if they remained in the top 25th percentile of overall patient ratings of inpatient experience from 2009 through 2013. We classified hospital characteristics as modifiable or unmodifiable. Modifiable characteristics are operational measures that hospitals can change to improve performance; these characteristics include registered nurse (RN) staffing levels, presence of hospitalists, and level of physician integration. Unmodifiable characteristics are core structural dimensions, such as hospital size and teaching status, that require substantial investment to change, as well as market-level factors such as competition and unemployment rates. Using logistic regression analysis, we found that RN staffing levels, Medicare share of inpatient days, teaching status, and market competition were significant predictors of the likelihood that a given hospital sustained high levels of patient ratings over time (i.e., the likelihood of a hospital being classified as a sustainer). Hospitals with a higher ratio of inpatient days to RN staffing and higher Medicare share of inpatient days had lower odds of being classified as sustainers.

College Women's Responses to a Celebrity Health Disclosure.

Celebrities can have a powerful influence on people's health-related attitudes and behaviors, often by publicly disclosing their own personal health decisions. In May 2013, Angelina Jolie, an internationally recognized actress, director, and author, wrote an op-ed for the New York Times disclosing her decision to undergo a prophylactic double mastectomy to reduce her risk of breast cancer after learning that she carried the BRCA1 gene mutation. This cross-sectional study examined whether exposure to Angelina Jolie and her mastectomy disclosure and parasocial involvement (PSI) with Angelina Jolie were related to female college students' perceived risk of breast cancer and breast cancer screening intentions. Participants were 198 female undergraduate college students. Data were collected anonymously via an online questionnaire and analyzed using bivariate correlations and hierarchical linear regression analyses. Neither exposure to Angelina and her disclosure nor PSI with Angelina Jolie was related to participants' attitudes or behaviors related to breast cancer. However, having a family history of cancer was associated with more exposure to Angelina Jolie and her disclosure. Findings suggest that exposure to and PSI with a celebrity who has disclosed a health-related message may not be sufficient to motivate young women to change their health-related attitudes and behaviors. Future studies should explore how celebrities disclosing different types of health issues might influence the attitudes and behaviors of young women.

Determining the spatial heterogeneity underlying racial and ethnic differences in timely mammography screening.

BACKGROUND: The leading cause of cancer death for women worldwide continues to be breast cancer. Early detection through timely mammography has been recognized to increase the probability of survival. While mammography rates have risen for many women in recent years, disparities in screening along racial/ethnic lines persist across nations. In this paper, we argue that the role of local context, as identified through spatial heterogeneity, is an unexplored dynamic which explains some of the gaps in mammography utilization by race/ethnicity. METHODS: We apply geographically weighted regression methods to responses from the 2008 Public Health Corporations' Southeastern Household Health Survey, to examine the spatial heterogeneity in mammograms in the Philadelphia metropolitan area. RESULTS: We find first aspatially that minority identity, in fact, increases the odds of a timely mammogram: 74% for non-Hispanic Blacks and 80% for Hispanic/Latinas. However, the geographically weighted regression confirms the relation of race/ethnicity to mammograms varies by space. Notably, the coefficients for Hispanic/Latinas are only significant in portions of the region. In other words, the increased odds of a timely mammography we found are not constant spatially. Other key variables that are known to influence timely screening, such as the source of healthcare and social capital, measured as community connection, also vary by space. CONCLUSIONS: These results have ramifications globally, demonstrating that the influence of individual characteristics which motivate, or inhibit, cancer screening may not be constant across space. This inconsistency calls for healthcare practitioners and outreach services to be mindful of the local context in their planning and resource allocation efforts.
