- Abstract
This observational study evaluated utilization of religious coping strategies among 95 African American women who were at increased risk for having a BRCA1/BRCA2 (BRCA1/2) mutation. Overall, women reported high levels of collaborative coping; however, women with fewer than 2 affected relatives (beta = -1.97, P = 0.04) and those who had a lower perceived risk of having a BRCA1/2 mutation (beta = -2.72, P = 0.01) reported significantly greater collaborative coping. These results suggest that African American women may be likely to use collaborative strategies to cope with cancer-related stressors. It may be important to discuss utilization of religious coping efforts during genetic counseling with African American women. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Mistrust of healthcare providers and systems is a significant barrier to quality healthcare. However, limited empirical data are available on perceptions of medical mistrust among individuals who are diagnosed with cancer. The objective of this study was to identify sociodemographic, clinical, and cultural determinants of mistrust among men diagnosed with prostate cancer.Methods: The authors conducted an observational study among 196 African-American men (n = 71) and white men (n = 125) who were newly diagnosed with prostate cancer during 2003 through 2007.Results: Race, education, healthcare experiences, and cultural factors had significant effects on mistrust. African-American men (P = .01) and men who had fewer years of formal education (P = .001) reported significantly greater levels of mistrust compared with white men and men who had more education. Mistrust also was greater among men who had been seeing their healthcare provider for a longer period (P = .01) and among men with lower perceptions of interdependence (P = .01).Conclusions: The current findings suggested that efforts to enhance trust among men who are diagnosed with prostate cancer should target African-American men, men with fewer socioeconomic resources, and men with lower perceptions of interdependence. Reasons for deterioration in trust associated with greater experience with specialty providers should be explored along with the effects of interventions that are designed to address the concerns of individuals who have greater mistrust.

- Abstract
Community-based participatory research (CBPR) is an important strategy for reducing racial disparities in health outcomes. Academic-community partnerships are central to CBPR; however, there are few examples of how to develop these partnerships for prostate cancer research. This report describes the methods used to develop an academic-community partnership between investigators at the University of Pennsylvania and members of the Philadelphia chapter of the National Black Leadership Initiative on Cancer for CBPR on quality of life following prostate cancer diagnosis. Our experiences demonstrate that a significant investment of time is needed to identify a community partner for prostate cancer research and develop an effective partnership. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: Initiating postoperative radiotherapy (PORT) within 6 weeks of surgery for head and neck squamous cell carcinoma (HNSCC) is included in the National Comprehensive Cancer Network Clincal Practice Guidelines and is a Commission on Cancer quality metric. Factors associated with delays in starting PORT have not been systematically described nor synthesized., Data Sources: PubMed, Scopus, and CINAHL., Review Methods: We included studies describing demographic characteristics, clinical factors, or social determinants of health associated with PORT delay (>6 weeks) in patients with HNSCC treated in the United States after 2003. Meta-analysis of odds ratios (ORs) was performed on nonoverlapping datasets., Results: Of 716 unique abstracts reviewed, 21 studies were included in the systematic review and 15 in the meta-analysis. Study sample size ranged from 19 to 60,776 patients. In the meta-analysis, factors associated with PORT delay included black race (OR, 1.46, 95% confidence interval [CI]: 1.28-1.67), Hispanic ethnicity (OR, 1.37, 95% CI, 1.17-1.60), Medicaid or no health insurance (OR, 2.01, 95% CI, 1.90-2.13), lower income (OR, 1.38, 95% CI, 1.20-1.59), postoperative admission >7 days (OR, 2.92, 95% CI, 2.31-3.67), and 30-day hospital readmission (OR, 1.37, 95% CI, 1.29-1.47)., Conclusion: Patients at greatest risk for a delay in initiating guideline-adherent PORT include those who are from minoritized communities, of lower socioeconomic status, and experience postoperative challenges. These findings provide the foundational evidence needed to deliver targeted interventions to enhance equity and quality in HNSCC care delivery., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

- Abstract
Importance: For patients with head and neck squamous cell carcinoma (HNSCC), initiation of postoperative radiation therapy (PORT) within 6 weeks of surgery is recommended by the National Comprehensive Cancer Network Guidelines and the Commission on Cancer. Although individual-level measures of socioeconomic status are associated with receipt of timely, guideline-adherent PORT, the role of neighborhood-level disadvantage has not been examined., Objective: To characterize the association of neighborhood-level disadvantage with delays in receiving PORT., Design, Setting, and Participants: This retrospective cohort study included 681 adult patients with HNSCC undergoing curative-intent surgery and PORT from 2018 to 2020 at 4 US academic medical centers. The data were analyzed between June 21, 2023, and March 5, 2024., Main Outcome Measures and Measures: The primary outcome was delay in initiating guideline-adherent PORT (ie, >6 weeks after surgery). Time-to-PORT (TTP) was a secondary outcome. Census block-level Area Deprivation Index (ADI) scores were calculated and reported as national percentiles (0-100); higher scores indicate greater deprivation. The association of ADI scores with PORT delay was assessed using multivariable logistic regression adjusted for demographic, clinical, and institutional characteristics. PORT initiation across ADI score population quartiles was evaluated with cumulative incidence plots and Cox models., Results: Among 681 patients with HNSCC undergoing surgery and PORT (mean [SD] age, 61.5 [11.2] years; 487 [71.5%] men, 194 [29.5%] women) the PORT delay rate was 60.8% (414/681) and median (IQR) TTP was 46 (40-56) days. The median (IQR) ADI score was 62.0 (44.0-83.0). Each 25-point increase in ADI score was associated with a corresponding 32% increase in the adjusted odds ratio (aOR) of PORT delay (aOR, 1.32; 95% CI, 1.07-1.63) on multivariable regression adjusted for institution, age, race and ethnicity, insurance, comorbidity, cancer subsite, stage, postoperative complications, care fragmentation, travel distance, and rurality. Increasing ADI score population quartiles were associated with increasing TTP (hazard ratio of PORT initiation, 0.71; 95% CI, 0.53-0.96; 0.59; 95% CI, 0.44-0.77; and 0.54; 95% CI, 0.41-0.72; for ADI quartiles 2, 3, and 4 vs ADI quartile 1, respectively)., Conclusions and Relevance: Increasing neighborhood-level disadvantage was independently associated with a greater likelihood of PORT delay and longer TTP in a dose-dependent manner. These findings indicate a critical need for the development of multilevel strategies to improve the equitable delivery of timely, guideline-adherent PORT.

- Abstract
Introduction: This study aimed to identify barriers and facilitators to the implementation of family cancer history (FCH) collection tools in clinical practices and community settings by assessing clinicians' perceptions of implementing a chatbot interface to collect FCH information and provide personalized results to patients and providers., Objectives: By identifying design and implementation features that facilitate tool adoption and integration into clinical workflows, this study can inform future FCH tool development and adoption in healthcare settings., Materials and Methods: Quantitative data were collected using survey to evaluate the implementation outcomes of acceptability, adoption, appropriateness, feasibility, and sustainability of the chatbot tool for collecting FCH. Semistructured interviews were conducted to gather qualitative data on respondents' experiences using the tool and recommendations for enhancements., Results: We completed data collection with 19 providers (n = 9, 47%), clinical staff (n = 5, 26%), administrators (n = 4, 21%), and other staff (n = 1, 5%) affiliated with the NCI Community Oncology Research Program. FCH was systematically collected using a wide range of tools at sites, with information being inserted into the patient's medical record. Participants found the chatbot tool to be highly acceptable, with the tool aligning with existing workflows, and were open to adopting the tool into their practice., Discussion and Conclusions: We further the evidence base about the appropriateness of scripted chatbots to support FCH collection. Although the tool had strong support, the varying clinical workflows across clinic sites necessitate that future FCH tool development accommodates customizable implementation strategies. Implementation support is necessary to overcome technical and logistical barriers to enhance the uptake of FCH tools in clinical practices and community settings., (© The Author(s) 2024.

- Abstract
Abstract: Social risk factors play an important role in minority health and cancer health disparities. Exposure to stress and stress responses are important social factors that are now included in conceptual models of cancer health disparities. This report summarizes results from studies that examined stress exposure and responses among African Americans. Data from studies that were conducted as part of a transdisciplinary and translational research center are also presented to provide additional insight about the nature of racial differences in specific stressors among African American and White prostate cancer patients., (Copyright © 2023 The Author(s).

- Abstract
Background/objective: Linking data is a critical feature of precision medicine initiatives that involves integrating information from multiple sources to improve researchers' and clinicians' ability to deliver care. We have limited understanding of how individuals perceive linking data as it relates to precision medicine. The aim of this study was to identify how sociodemographics, comorbidities, and beliefs about precision medicine influence two outcomes related to linking data: beliefs about linking data and concerns about linking data among men., Methods: We recruited 124 adult men from primary care practices at a large clinical research university to complete a cross-sectional survey that included questions about sociodemographic characteristics, comorbidities, beliefs, benefits, and limitations of precision medicine, and two outcomes of interest: beliefs about the value of linking data and concerns about linking data. Descriptive statistics, bivariate associations, and multivariable regression were conducted., Results: Participants had positive beliefs about linking data for precision medicine (M = 4.05/5) and average concern about linking data (M = 2.1/5). Final multivariable models revealed that higher levels of loneliness are associated with more positive beliefs about linking data (β = 0.41, p = 0.027). Races other than African American (β = -0.64, p = 0.009) and those with lower perceived limitations of precision medicine were less likely to be concerned about linking data (β = -0.75, p = 0.0006)., Conclusion: Our results advance the literature about perceptions of linking data for use in clinical and research studies among men. Better understanding of factors associated with more positive perceptions of data linkages could help improve how researchers recruit and engage participants., Competing Interests: The authors have no competing interests to declare., (© The Author(s) 2023.)

- Abstract
A cancer diagnosis can upend work and family life, leading patients to reallocate resources away from essentials such as food. Estimates of the percentage of people navigating a cancer diagnosis and food insecurity range between 17% and 55% of the cancer patient population. The complexity of addressing food insecurity among those diagnosed with cancer during different phases of treatment is multifactorial and often requires an extensive network of support throughout each phase. This commentary explores the issue of food insecurity in the context of cancer care, explores current mitigation efforts, and offers a call to action to create a path for food insecurity mitigation in the context of cancer. Three programs that address food insecurity among those with cancer at various stages of care are highlighted, drawing attention to current impact and actionable recommendations to make programs like these scalable and sustainable. Recommendations are grounded in the National Academies of Sciences, Engineering, and Medicine social care framework through 5 essential domain areas: awareness, adjustment, assistance, alignment, and advocacy. This commentary seeks to highlight opportunities for the optimization of cancer care and reframe food access as an essential part of treatment and long-term care plans., (© The Author(s) 2022.

- Abstract
Since the completion of the Human Genome Project, considerable progress has been made in translating knowledge about the genetic basis of disease risk and treatment response into clinical services and public health interventions that have greater precision. It is anticipated that more precision approaches to early detection, prevention, and treatment will be developed and will enhance equity in healthcare and outcomes among disparity populations. Reduced access to genomic medicine research, clinical services, and public health interventions has the potential to exacerbate disparities in genomic medicine. The purpose of this article is to describe these challenges to equity in genomic medicine and identify opportunities and future directions for addressing these issues. Efforts are needed to enhance access to genomic medicine research, clinical services, and public health interventions, and additional research that examines the clinical utility of precision medicine among disparity populations should be prioritized to ensure equity in genomic medicine.

- Abstract
Achieving health equity among disparity populations has been a national, regional, and local priority for several years. Health promotion and disease prevention behaviors play an important role in achieving health equity; the first generation of behavioral science studies in minority health and health disparities have provided important insights about the nature and distribution of risk exposure behaviors in disparity populations. Interventions have also been developed to enhance health promotion and disease prevention behaviors using behavioral counseling, tailored health communications, and interventions that are developed collaboratively with community stakeholders. Although intervention development and evaluation are components of transdisciplinary translational behavior research, discovery science is a critical first step in translational research. Consistent with this, conceptual models and frameworks of minority health and health disparities have evolved to include multilevel determinants that include basic behavioral mechanisms such as stress responses and stress reactivity that have physiological, psychological, and behavioral components that are relevant to minority health and health disparities. This report describes priorities, opportunities, and barriers to conducting transdisciplinary translational behavioral research during the next generation of minority health and health disparities research., (© The Author(s) 2021.

- Abstract
The purpose of this study was to examine the association between neighborhood social deprivation and individual-level characteristics on breast cancer staging in African American and white breast cancer patients. We established a retrospective cohort of patients with breast cancer diagnosed from 1996 to 2015 using the South Carolina Central Cancer Registry. We abstracted sociodemographic and clinical variables from the registry and linked these data to a county-level composite that captured neighborhood social conditions-the social deprivation index (SDI). Data were analyzed using chi-square tests, Student's t -test, and multivariable ordinal regression analysis to evaluate associations. The study sample included 52,803 female patients with breast cancer. Results from the multivariable ordinal regression model demonstrate that higher SDI (OR = 1.06, 95% CI: 1.02-1.10), African American race (OR = 1.35, 95% CI: 1.29-1.41), and being unmarried (OR = 1.17, 95% CI: 1.13-1.22) were associated with a distant stage at diagnosis. Higher tumor grade, younger age, and more recent year of diagnosis were also associated with distant-stage diagnosis. As a proxy for neighborhood context, the SDI can be used by cancer registries and related population-based studies to identify geographic areas that could be prioritized for cancer prevention and control efforts.

- Abstract
Purpose: The purpose of this study was to examine racial differences in patient portal activation and research participation among patients with prostate cancer., Materials and Methods: Participants were African American and White patients with prostate cancer who were treated with radical prostatectomy (n = 218). Patient portal activation was determined using electronic health records, and research participation was measured based on completion of a social determinants survey., Results: Thirty-one percent of patients completed the social determinants survey and enrolled in the study and 66% activated a patient portal. The likelihood of enrolling in the study was reduced with greater levels of social deprivation (odds ratio [OR], 0.70; 95% CI, 0.50 to 0.98; P = .04). Social deprivation also had a signification independent association with patient portal activation along with racial background. African American patients (OR, 0.48; 95% CI, 0.23 to 0.91; P = .02) and those with greater social deprivation (OR, 0.58; 95% CI, 0.42 to 0.82; P = .002) had a lower likelihood of activating a patient portal compared with White patients and those with lower social deprivation., Conclusion: Although the majority of patients with prostate cancer activated their patient portal, rates of patient portal activation were lower among African American patients and those who lived in areas with greater social deprivation. Greater efforts are needed to promote patient portal activation among African American patients with prostate cancer and address access to health information technology among those who live in socially disadvantaged geographic areas., Competing Interests: Michael LillySpeakers' Bureau: Guardant HealthResearch Funding: Bavarian Nordic, BayerNo other potential conflicts of interest were reported.

- Abstract
Purpose: Physical activity is important for enhancing quality of life and cancer control among prostate cancer survivors. The purpose of this study was to characterize adherence to physical activity guidelines among African American and white prostate cancer survivors based on social and clinical determinants and psychosocial factors., Methods: Observational study of meeting guidelines for moderate intensity physical activity in a retrospective cohort of African American and white prostate cancer survivors (n = 89)., Results: Thirty-four percent of survivors met the recommended guidelines for moderate intensity physical activity. There were no racial differences in physical activity between African American and white prostate cancer survivors; however, the likelihood of meeting guidelines was associated significantly with stage of disease, self-rated health, and perceptions of stress. Survivors who had stage pT2c or higher disease had a significantly reduced likelihood of meeting recommended guidelines for physical activity (OR = 0.27, 95% CI = 0.08, 0.86, p = 0.03). The likelihood of meeting guidelines was also reduced among survivors who rated their health as being the same or worse than before they were diagnosed with prostate cancer (OR = 0.32, 95% CI = 0.11, 0.96, p = 0.04). As perceived stress increased, the likelihood of being physically active according to guidelines also decreased (OR = 0.48, 95% CI = 0.26, 0.89, p = 0.02)., Conclusion: The results of this study underscore the need to develop, implement, and evaluate strategies to enhance physical activity among prostate cancer survivors, regardless of their racial background. Complementary and alternative strategies for physical activity may be one strategy for enhancing activity levels and managing stress among prostate cancer survivors.

- Abstract
Purpose: Delays initiating guideline-adherent postoperative radiation therapy (PORT) in head and neck squamous cell carcinoma (HNSCC) are common, contribute to excess mortality, and are a modifiable target for improving survival. However, the barriers that prevent the delivery of timely, guideline-adherent PORT remain unknown. This study aims to identify the multilevel barriers to timely, guideline-adherent PORT and organize them into a conceptual model., Materials and Methods: Semi-structured interviews with key informants were conducted with a purposive sample of patients with HNSCC and oncology providers across diverse practice settings until thematic saturation (n = 45). Thematic analysis was performed to identify the themes that explain barriers to timely PORT and to develop a conceptual model., Results: In all, 27 patients with HNSCC undergoing surgery and PORT were included, of whom 41% were African American, and 37% had surgery and PORT at different facilities. Eighteen clinicians representing a diverse mix of provider types from 7 oncology practices participated in key informant interviews. Five key themes representing barriers to timely PORT were identified across 5 health care delivery levels: (1) inadequate education about timely PORT, (2) postsurgical sequelae that interrupt the tight treatment timeline (both intrapersonal level), (3) insufficient coordination and communication during care transitions (interpersonal and health care team levels), (4) fragmentation of care across health care organizations (organizational level), and (5) travel burden for socioeconomically disadvantaged patients (community level)., Conclusion: This study provides a novel description of the multilevel barriers that contribute to delayed PORT. Interventions targeting these multilevel barriers could improve the delivery of timely, guideline-adherent PORT and decrease mortality for patients with HNSCC.

- Abstract
The Transdisciplinary Collaborative Center (TCC) in Precision Medicine for Minority Men's Health was established at the Medical University of South Carolina (MUSC) in 2015 to address disparities in the translation of precision medicine approaches among racial minority groups. This regional consortium focuses on three primary areas: (1) the development of a consortium of regional and national partners, (2) conducting transdisciplinary research examining synergistic effects of biological, social, physiological, and clinical determinants of chronic disease risks and outcomes, and (3) dissemination and implementation of precision medicine approaches, with an emphasis on reducing disparities in health care and outcomes among minority men. Given consistent calls to better translate precision medicine approaches and the focus of this consortium on addressing disparities among minority men, we provide an overview of our experience in developing the MUSC TCC, including barriers and facilitators to conducting translational research on minority men's health issues in the context of precision medicine. Lessons learned and areas for improvement include providing enough time to create consistent partnerships and community engagement to improve recruitment and retention, identifying unique ways to engage diverse partners from across the region and nation, and better approaches to dissemination and communication for large partnerships focusing on precision medicine.

- Abstract
Objectives: Physiological stress responses have been suggested as a mechanism through which social and biological factors contribute to racial disparities in breast cancer outcomes. Many African Americans experience stressful life events and circumstances. These social factors may contribute to an increased risk of advanced stage disease at diagnosis and/or faster progression, but not all African American women exposed to adverse social factors develop advanced stage disease. Similarly, women who have a limited number of stressors can develop advanced stage breast cancer. Highly individualized stress reactivity may account for these inconsistent associations., Method: This report describes the rationale, design, and methods for an exploratory study that uses the experimental medicine approach to: (a) characterize the nature and distribution of stress reactivity among African American breast cancer survivors based on socioeconomic, clinical, and social stressors; (b) examine the impact of stress reactivity on temporal discounting; and (c) determine the extent to which stress reactivity and temporal discounting are associated with adherence to recommendations for cancer control behaviors and treatment compliance as part of the Science of Behavior Change Network., Results: This study addresses several empirical gaps about the most effective ways to develop behavior change interventions for a medically underserved population that continues to experience disparities in cancer morbidity and mortality., Conclusions: Results from this research will provide the empirical and conceptual basis for future intervention protocols that target mechanisms that are critical to disparities in African American breast cancer survivors.

- Abstract
Background: Financial stress, one of the social determinants, is common among cancer patients because of high out-ofpocket costs for treatment, as well as indirect costs. The National Academy of Medicine (NAM) has advised providers to recognize and discuss cost concerns with patients in order to enhance shared decision-making for treatment and exploration of financial assistant programs. However, financial stress is rarely assessed in clinical practice or research, thus, under-coded and under-documented in clinical practice. Natural language processing (NLP) offers great potential that can automatically extract and process data on financial stress from clinical free text existing in the patient electronic health record (EHR)., Methods: We developed and evaluated an NLP approach to identify financial stress from clinical narratives for patients with prostate cancer. Of 4,195 eligible prostate cancer patients, we randomly sampled 3,138 patients (75%) as a training dataset (150,990 documents) to develop a financial stress lexicon and NLP algorithms iteratively. The remaining 1,057 patients (25%) were used as a test dataset (55,516 documents) to evaluate the NLP algorithm performance. The common terms representing financial stress were "financial concerns," "unable to afford," "insurance issue," "unemployed," and "financial assistance." Negations were used to exclude false mentions of financial stress., Results: Applying both pre- and post-negation, the NLP algorithm identified 209 patients (6.0%) from the training sample and 66 patients (6.2%) with 161 notes from the test sample as having documented financial stress. Two independent domain experts manually reviewed all 161 notes with NLP identified positives and randomly selected 161 notes with NLP-identified negatives, the NLP algorithm yielded 0.86 for precision, 1 for recall, and 0.9.2 for F-score., Conclusions: Financial stress information is not commonly documented in the EHR, neither in structured format nor in clinical narratives. However, natural language processing can accurately extract financial stress information from clinical notes when such narrative information is available., Competing Interests: Competing interesting None of the authors has any competing interests.

- Abstract
Background: Social isolation is an important social determinant that impacts health outcomes and mortality among patients. The National Academy of Medicine recently recommended that social isolation be documented in electronic health records (EHR). However, social isolation usually is not recorded or obtained as coded data but rather collected from patient self-report or documented in clinical narratives. This study explores the feasibility and effectiveness of natural language processing (NLP) strategy for identifying patients who are socially isolated from clinical narratives., Method: We used data from the Medical University of South Carolina (MUSC) Research Data Warehouse. Patients 18 years-of-age or older who were diagnosed with prostate cancer between January 1, 2014 and May 31, 2017 were eligible for this study. NLP pipelines identifying social isolation were developed via extraction of notes on progress, history and physical, consult, emergency department provider, telephone encounter, discharge summary, plan of care, and radiation oncology. Of 4195 eligible prostate cancer patients, we randomly sampled 3138 patients (75%) as a training dataset. The remaining 1057 patients (25%) were used as a test dataset to evaluate NLP algorithm performance. Standard performance measures for the NLP algorithm, including precision, recall, and F-measure, were assessed by expert manual review using the test dataset., Results: A total of 55,516 clinical notes from 3138 patients were included to develop the lexicon and NLP pipelines for social isolation. Of those, 35 unique patients (1.2%) had social isolation mention(s) in 217 notes. Among 24 terms relevant to social isolation, the most prevalent were "lack of social support," "lonely," "social isolation," "no friends," and "loneliness". Among 1057 patients in the test dataset, 17 patients (1.6%) were identified as having social isolation mention(s) in 40 clinical notes. Manual review identified four false positive mentions of social isolation and one false negatives in 154 notes from randomly selected 52 controls. The NLP pipeline demonstrated 90% precision, 97% recall, and 93% F-measure. The major reasons for a false positive included the ambiguities of the experiencer of social isolation, negation, and alternate meaning of words., Conclusions: Our NLP algorithms demonstrate a highly accurate approach to identify social isolation.

- Abstract
Precision medicine includes the use of genetic variation to determine the prevention, pathology, management, and treatment of disease, which has the potential to significantly change the practice of healthcare. As such, its success depends on (a) having reliable information about the effects of genetic variation on disease processes; and (b) the patient's understanding of their own genetic makeup such that they can use that information to affect their lifestyle and diet. Given the history of low engagement of under-represented minority populations in both clinical genetic services and genetic research, both of these aspects will be challenged and must be addressed before the benefits of precision medicine will be fully realized. Reflecting on lessons learned in the field of cancer genetic counseling, we present key issues to consider as we look forward to providing genetic counseling to minority communities in the context of precision medicine., (© 2018 Wiley Periodicals, Inc.)

- Abstract
Despite efforts to promote healthy weight, obesity is at epidemic levels among adults in the US. We examined the prevalence of weight loss attempts among a racially diverse sample of overweight and obese primary care patients (n = 274) based on sociodemographic, clinical and psychological factors, and shared decision-making (SDM) about weight loss/management. This observational study was conducted from December 2015 through January 2017. Data were obtained by self-report via survey. Overall, 64% of participants were attempting to lose weight at the time of survey. No significant differences in current weight loss attempts were found based on racial background, sociodemographic characteristics, or clinical factors. Participants who believed they were obese/overweight (OR = 6.70, 95% CI = 2.86, 15.72, p < 0.0001) or who were ready to lose/manage their weight (OR = 4.50, 95% CI = 1.82, 11.09, p = 0.001) had an increased likelihood of attempting to lose weight. The likelihood of attempting to lose weight increased with greater SDM with providers (OR = 1.54, 95% CI = 1.06, 2.22, p = 0.02). Patient perceptions about their weight, their readiness for weight loss/management, and SDM were associated significantly with weight loss attempts.

- Abstract
Objective: Primary care providers play an important role in obesity prevention and reduction by advising patients about weight loss strategies. This study examined receipt of provider advice to lose weight among primary care patients who were overweight and obese., Methods: Observational study conducted among primary care patients (n = 282) who completed a survey that measured receipt of provider advice about weight loss/management, chronic health conditions, perceived weight status, and perceptions about shared decision making about weight loss/management., Results: Fifty-nine percent of participants had been advised by their physician to lose weight. Participants who were obese were more likely than those who were overweight to report provider advice (odds ratio [OR] = 1.31, 95% CI = 1.25-4.34, P = .001). Similarly, participants who believed they were obese/overweight had a greater likelihood of reporting provider advice compared with those who did not believe they were obese/overweight (OR = 1.40, 95% CI = 2.43-6.37, P = .0001). Shared decision making about weight loss/management was associated with an increased likelihood of reporting provider advice (OR = 3.30, 95% CI = 2.62-4.12, P = .0001)., Conclusions: Patient beliefs about their weight status and perceptions about shared decision-making are important to receiving provider advice about weight loss/management among primary care patients., Practice Implications: Continued efforts are needed to enhance provider advice about weight loss/management among obese/overweight patients.

- Abstract
Obesity and excess weight are significant clinical and public health issues that disproportionately affect African Americans because of physical inactivity and unhealthy eating. We compared the effects of alternate behavioral interventions on obesity-related health behaviors. We conducted a comparative effectiveness education trial in a community-based sample of 530 adult African Americans. Outcomes variables were physical activity (PA) and fruit and vegetable intake. Outcomes were evaluated at baseline and 1-month following interventions about shared risk factors for cancer and cardiovascular disease (CVD) (integrated, INT) or CVD only (disease-specific). Significant increases were found in the proportion of participants who met PA guidelines from baseline (47.4%) to follow-up (52.4%) (P = 0.005). In the stratified analysis that were conducted to examine interaction between education and intervention group assignment, this effect was most apparent among participants who had ≤high school education and were randomized to INT (OR = 2.28, 95% CI = 1.04, 5.00, P = 0.04). Completing the intervention was associated with a 1.78 odds of meeting PA guidelines (95% CI = 1.02, 3.10, P = 0.04). Education about risk factors for chronic disease and evidence-based strategies for health behavior change may be useful for addressing obesity-related behaviors among African Americans., (© The Author 2017.

- Abstract
We examined beliefs about genetically targeted care (GTC) among African American men and women in a hospital-based sample and identified sociodemographic, cultural, and clinical factors having significant independent associations with these beliefs. Specifically, beliefs about GTC were evaluated after respondents were randomly primed with a racial or non-racial cue about race and genetics. Despite priming with a racial or non-racial cue, many respondents had positive beliefs about GTC. But, 49% believed that GTC would limit access to medical treatment, 46% believed that people will not trust GTC, and 20% believed that people like them would not benefit from GTC. Racial and non-racial priming did not have significant associations with negative beliefs about GTC. However, cultural beliefs related to temporal orientation were associated significantly with believing that genetically targeted care will limit access to medical treatment. Greater levels of future temporal orientation were associated with a reduced likelihood of endorsing this belief (OR = 0.70, 95% CI = 0.49, 1.01, p = 0.05). Respondents who had a chronic medical condition had an almost three-fold greater likelihood of believing that they would not benefit from GTC (OR = 2.90, 95% CI = 1.00, 8.37, p = 0.05). Greater exposure to information about genetic testing for chronic conditions was also associated with a reduced likelihood of believing that they would not benefit from GTC (OR = 0.40, 95% CI = 0.64, 0.91, p = 0.02). African Americans have diverse beliefs about GTC that should be considered as genetic and genomic services are offered., (Copyright © 2017. Published by Elsevier Inc.)

- Abstract
Purpose: Black women are more likely to develop early-onset (≤50 years) breast cancer (BC) and have the lowest five-year, cause-specific survival rate of any United States (U.S.) racial or ethnic group. These disparities can be attributed partially to the higher rate of triple-negative BC (TNBC) in Blacks. Yet, little is known about health-related quality of life (HRQOL) among Black women with TNBC., Methods: Black women with invasive BC ≤ 50 years were recruited via the Florida Cancer Data System as part of a population-based case-only study of etiology and outcomes of early-onset invasive BC. Of 460 consented participants, a subset of 355 self-reported sociodemographic, clinical, and psychosocial variables. Descriptive analyses included participants with known TNBC (n = 85) or non-TNBC (n = 245) disease. Univariable and multivariable analyses were conducted to examine differences in factors associated with HRQOL., Results: In unadjusted analyses, TNBC participants had significantly lower FACT-B total scores (90.1 ± 27.9) compared to non-TNBC (98.5 ± 27.6) participants (p < 0.05). For the TNBC group, multivariable analyses indicated five individual-level, and three systemic-level factors explain 80% of the response variation in HRQOL. For the non-TNBC group, seven individual-level factors and three systemic-level factors account for 76% of the variation in HRQOL scores., Conclusions: Compared to Black women with non-TNBC, TNBC women have worse HRQOL. There are key individual and systemic-level factors that are unique to both groups. Findings can inform future HRQOL interventions to support young Black BC survivors.

- Abstract
As guidelines for prostate cancer screening have changed from an annual screening recommendation starting at age 50 to discussing the benefits and harms of screening with health care providers, it is necessary to examine other types of factors that are important to prostate cancer screening decisions among African American men. Perceived risk of developing cancer has been shown to predict cancer control behaviors and is lower among African Americans. We characterized perceived risk of developing prostate cancer among African American men from November 2009 to 2011 and evaluated the relationship between prostate cancer risk perceptions and sociodemographic characteristics, health care experiences, and knowledge and exposure to health information about cancer. Chi square tests and logistic regression were employed to determine independent associations. Overall, men did not believe they were at increased risk of developing prostate cancer; they believed their risk was equivalent to or lower than men the same age. Perceived risk of prostate cancer was associated with income (OR = 0.59, 95% CI = 0.26, 1.34, p = 0.03), hypertension (OR = 2.68, 95% CI = 1.17, 6.16, p = 0.02), and beliefs about the association between race and cancer risk (OR = 2.54, 95% CI = 1.24, 5.20, p = 0.01). Clinic and community-based approaches to improve prostate cancer risk comprehension among African American men are needed to reduce the discordance between perceived risk and epidemiological data on prostate cancer risk factors. Risk education interventions that are developed for African American men may need to integrate information about susceptibility for multiple diseases as well as address strategies for risk reduction and prevention, and chronic disease management.

- Abstract
Although the association between social context and health has been demonstrated previously, much less is known about network interactions by gender, race/ethnicity, and sociodemographic characteristics. Given the variability in cancer outcomes among groups, research on these relationships may have important implications for addressing cancer health disparities. We examined the literature on social networks and cancer across the cancer continuum among adults. Relevant studies (N=16) were identified using two common databases: PubMed and Google Scholar. Most studies used a prospective cohort study design (n=9), included women only (n=11), and were located in the United States (n=14). Seventy-five percent of the studies reviewed used a validated scale or validated items to measure social networks (n=12). Only one study examined social network differences by race, 57.1% (n=8) focused on breast cancer alone, 14.3% (n=2) explored colorectal cancer or multiple cancers simultaneously, and 7.1% (n=1) only prostate cancer. More than half of the studies included multiple ethnicities in the sample, while one study included only low-income subjects. Despite findings of associations between social networks and cancer survival, risk, and screening, none of the studies utilized social networks as a mechanism for reducing health disparities; however, such an approach has been utilized for infectious disease control. Social networks and the support provided within these networks have important implications for health behaviors and ultimately cancer disparities. This review serves as the first step toward dialog on social networks as a missing component in the social determinants of cancer disparities literature that could move the needle upstream to target adverse cancer outcomes among vulnerable populations., (© 2017 Elsevier Inc.

- Abstract
Since prostate cancer continues to disproportionately affect African American men in terms of incidence, morbidity, and mortality, prostate-specific antigen (PSA) screening plays an important role in early detection, especially when men engage in informed decision making to accept or decline this test. The authors evaluated utilization of PSA testing among African American men based on factors that are important components of making informed decisions. Utilization of PSA testing was evaluated based on whether men had ever had PSA testing and PSA testing during the past year in a community-based sample of African American men ages 50 to 75 ( n = 132). Overall, 64% of men ( n = 85) reported that they had ever had a PSA test; the mean ( SD) age for first use of PSA testing was 47.7 ( SD = 7.4). The likelihood of ever having a PSA test increased significantly with physician communication (odds ratio [OR] = 14.2; 95% confidence interval [CI] = 4.20, 48.10; p = .0001) and with having an annual household income that was greater than $20,000 (OR = 9.80; 95% CI = 3.15, 30.51; p = .0001). The odds of ever having a PSA test were also decreased with each unit increase in future temporal orientation (OR = 0.66; 95% CI = 0.47, 0.93; p = .02). Of the men who had ever had PSA testing, 57% were screened during the past year. Only health insurance status had a significant independent association with having annual PSA testing (OR = 5.10; 95% CI = 1.67, 15.60; p = .004). Different factors were associated significantly with ever having PSA testing and annual testing among African American men. African American men may not be making an informed decision about prostate cancer screening.

- Abstract
Background: The premise of community advocacy is to empower residents by increasing their capacity to address and change neighborhood and structural factors that contribute to adverse health outcomes. An underlying assumption is that community residents will advocate for public policy and other changes. However, limited empirical evidence exists on community residents' perceived ability to advocate for neighborhood change. In this study, we characterized perceived neighborhood control and efficacy for neighborhood change and evaluated independent associations between efficacy and control beliefs and sociodemographic factors, community involvement, and perceptions of social environment., Methods: Cross-sectional data from 488 African American adults were analyzed to describe efficacy and control beliefs and to characterize bivariate associations between these beliefs and sociodemographic factors, social environment, and community involvement variables. Variables with significant relationships (p < 0.10) were included in a multivariate logistic regression model to identify factors having significant independent associations with efficacy and control beliefs., Results: Overall, beliefs about neighborhood control and confidence were varied, yet approximately half of residents (49 and 55 %, respectively) reported having a little control over things that happen in their neighborhood and a little confidence in their ability to change things where they live. The likelihood of reporting confidence to make neighborhood improvements increased with greater collective efficacy (OR = 1.78, 95 % CI = 1.19-1.31, p = 0.002). In addition, participants who were involved in a community organization were more likely to report confidence to improve their neighborhood (OR = 2.03, 95 % CI = 1.21-3.42, p = 0.01)., Conclusion: Efforts are needed to improve residents' ability to become positive agents of change in their community. Creating a research infrastructure within academic community partnerships that focus on strengthening advocacy and public policy may improve resident's efficacy and ability to seek and encourage neighborhood change., Competing Interests: Compliance with Ethical Standards: Conflicts of interest: Author LJR declares he/she has no conflict of interest.

- Abstract
Rationale: The U.S. Preventive Services Task Force recommends annual low-dose computed tomography (LDCT) for lung cancer screening in high-risk individuals. Preventive healthcare is provided predominantly by primary care providers (PCPs). Successful implementation of a screening program requires acceptance and participation by both providers and patients, with available collaboration with pulmonologists., Objectives: To identify perceptions of and perspectives on lung cancer screening and implementation among PCPs and eligible veteran patients at high risk for lung cancer., Methods: We conducted a qualitative study using grounded theory in which 28 veterans and 13 PCPs completed a questionnaire and participated in focus groups. Sessions were recorded, transcribed verbatim, and analyzed with NVivo 10 software. Counts and percentages were used to report questionnaire results., Measurements and Main Results: While 58% percent of providers were aware of lung cancer screening guidelines, many could not recall the exact patient eligibility criteria. Most patients were willing to undergo LDCT screening and identified smoking as a risk factor for lung cancer, but they did not recall their PCP explaining the reason for the testing. All providers assessed smoking behavior, but only 23% referred active smokers for formal cessation services. Patients volunteered information regarding their hurdles with smoking cessation while discussing risk factors for cancer. PCPs cited time constraints as a reason for lack of appropriate counseling and shared decision making. Both parties were willing to explore modalities and decision aid tools to improve shared decision making; however, while patients were interested in individual risk prediction, few PCPs believed statistical approaches to counseling would confuse patients., Conclusions: While patients and providers are receptive to LDCT screening, efforts are needed to improve guideline knowledge and adherence among providers. System-level interventions are necessary to facilitate time and resources for shared decision making and smoking cessation counseling and treatment. Further research is needed to identify optimal strategies for effective lung cancer screening in the community.

- Abstract
Introduction: Many factors influence women's decisions to participate in guideline-recommended screening mammography. We evaluated the influence of women's socioeconomic characteristics, health-care access, and cultural and psychological health-care preferences on timely mammography screening participation., Materials and Methods: A random digit dial survey of United States non-Hispanic Black, non-Hispanic White, and Hispanic women aged 40-75, from January to August 2009, determined self-reported time of most recent mammogram. Screening rates were assessed based on receipt of a screening mammogram within the prior 12 months, the interval recommended at the time by the American Cancer Society., Results: Thirty-nine percent of women reported not having a mammogram within the last 12 months. The odds of not having had a screening mammography were higher for non-Hispanic White women than for non-Hispanic Black (OR = 2.16, 95% CI = 0.26, 0.82, p = 0.009) or Hispanic (OR = 4.17, 95% CI = 0.12, 0.48, p = 0.01) women. Lack of health insurance (OR = 3.22, 95% CI = 1.54, 6.73, p = 0.002) and lack of usual source of medical care (OR = 3.37, 95% CI = 1.43, 7.94, p = 0.01) were associated with not being screened as were lower self-efficacy to obtain screening (OR = 2.43, 95% CI = 1.26, 4.73, p = 0.01) and greater levels of religiosity and spirituality (OR = 1.42, 95% CI = 1.00, 2.00, p = 0.05). Neither perceived risk nor present temporal orientation was significant., Discussion: Odds of not having a mammogram increased if women were uninsured, without medical care, non-Hispanic White, older in age, not confident in their ability to obtain screening, or held passive or external religious/spiritual values. Results are encouraging given racial disparities in health-care participation and suggest that efforts to increase screening among minority women may be working.

- Abstract
Importance: Precision medicine is an approach to detecting, treating, and managing disease that is based on individual variation in genetic, environmental, and lifestyle factors. Precision medicine is expected to reduce health disparities, but this will be possible only if studies have adequate representation of racial minorities., Objective: It is critical to anticipate the rates at which individuals from diverse populations are likely to participate in precision medicine studies as research initiatives are being developed. We evaluated the likelihood of participating in a clinical study for precision medicine., Design, Setting, Participants: Observational study conducted between October 2010 and February 2011 in a national sample of African Americans., Main Outcome Measure: Intentions to participate in a government sponsored study that involves providing a biospecimen and generates data that could be shared with other researchers to conduct future studies., Results: One third of respondents would participate in a clinical study for precision medicine. Only gender had a significant independent association with participation intentions. Men had a 1.86 (95% CI = 1.11, 3.12, p = 0.02) increased likelihood of participating in a precision medicine study compared to women in the model that included overall barriers and facilitators. In the model with specific participation barriers, distrust was associated with a reduced likelihood of participating in the research described in the vignette (OR = 0.57, 95% CI = 0.34, 0.96, p = 0.04)., Conclusion and Relevance: African Americans may have low enrollment in PMI research. As PMI research is implemented, extensive efforts will be needed to ensure adequate representation. Additional research is needed to identify optimal ways of ethically describing precision medicine studies to ensure sufficient recruitment of racial minorities.

Aim: African-Americans (AA) have increased prostate cancer risk and a greater mortality rate than European-Americans (EA). AA exhibit a high prevalence of vitamin D deficiency. We examined the global prostate transcriptome in AA and EA, and the effect of vitamin D
3 supplementation., Patients & Methods: Twenty-seven male subjects (ten AA and 17 EA), slated to undergo prostatectomy were enrolled in the study. Fourteen subjects received vitamin D3 (4000 IU daily) and 13 subjects received placebo for 2 months prior to surgery., Results: AA show higher expression of genes associated with immune response and inflammation., Conclusion: Systems level analyses support the concept that Inflammatory processes may contribute to disease progression in AA. These transcripts can be modulated by a short course of vitamin D3 supplementation.- Published

- Abstract
Rationale: Smoking is the largest contributor to lung cancer risk, and those who continue to smoke after diagnosis have a worse survival. Screening for lung cancer with low-dose computed tomography (LDCT) reduces mortality in high-risk individuals. Smoking cessation is an essential component of a high-quality screening program., Objectives: To quantify the effects of smoking history and abstinence on mortality in high-risk individuals who participated in the NLST (National Lung Screening Trial)., Methods: This is a secondary analysis of a randomized controlled trial (NLST)., Measurements and Main Results: Measurements included self-reported demographics, medical and smoking history, and lung cancer-specific and all-cause mortality. Cox regression was used to study the association of mortality with smoking status and pack-years. Kaplan-Meier survival curves were examined for differences in survival based on trial arm and smoking status. Current smokers had an increased lung cancer-specific (hazard ratio [HR], 2.14-2.29) and all-cause mortality (HR, 1.79-1.85) compared with former smokers irrespective of screening arm. Former smokers in the control arm abstinent for 7 years had a 20% mortality reduction comparable with the benefit reported with LDCT screening in the NLST. The maximum benefit was seen with the combination of smoking abstinence at 15 years and LDCT screening, which resulted in a 38% reduction in lung cancer-specific mortality (HR, 0.62; 95% confidence interval, 0.51-0.76)., Conclusions: Seven years of smoking abstinence reduced lung cancer-specific mortality at a magnitude comparable with LDCT screening. This reduction was greater when abstinence was combined with screening, highlighting the importance of smoking cessation efforts in screening programs.

- Abstract
Social determinants are important to cancer screening among African Americans. To evaluate the association between social determinants (e.g., psychological characteristics, perceived social environment, cultural beliefs such as present temporal orientation) and colorectal cancer (CRC) screening among African Americans. African American adults (n = 262) ages 50-75 completed a telephone interview. Multivariate logistic regression analysis was used to identify factors having significant independent associations with CRC screening. Only 57% of respondents reported having CRC screening. The likelihood of screening increased with greater neighborhood satisfaction (OR = 1.38, 95% CI = 1.01, 1.90, p = 0.04), older age (OR = 1.75, 95% CI = 1.24, 2.48, p = 0.002), greater self-efficacy (OR = 2.73, 95% CI = 1.40, 5.35, p = 0.003), and health care provider communication (OR = 10.78, 95% CI = 4.85, 29.94, p = 0.0001). Community resources are important precursors to CRC screening and outcomes among African Americans. In addition to addressing psychological factors and patient-provider communication, efforts to ensure the availability of quality health care facilities that provide CRC screening in the neighborhoods where African Americans live are needed.

- Abstract
Background: The intervention completion rate is an important metric in behavioral and intervention research; trials with limited intervention completion rates may have reduced internal validity. We examined intervention completion rates among 530 African Americans who had been randomized to an integrated (INT) or disease-specific (DSE) risk education protocol as part of a comparative effectiveness trial from September 2009 to August 2012., Methods: The interventions were developed by an academic-community partnership using community-based participatory research. Intervention completion rates were determined based on attendance at all four intervention sessions. Intervention completers were participants who completed all four sessions and noncompleters were those who did not complete any session or only completed one to three sessions following randomization., Results: Seventy-three percent of participants were intervention completers and 27% were noncompleters. There were no differences in intervention completion based on randomization to INT (72%) or DSE (75%), sociodemographic factors, or body mass index (BMI) in the total sample. Different factors were associated significantly with intervention completion within study groups. Among participants randomized to INT, the odds of intervention completion were greater with higher levels of intrinsic motivation, less exposure to information about diet and cardiovascular disease, and greater BMI. Among participants randomized to DSE, the odds of completing the intervention were associated significantly with older age and greater dietary self-efficacy., Conclusions: Many African Americans are likely to complete risk education interventions., Impact: Psychologic characteristics should be considered when determining intervention completion rates following randomization in behavioral and intervention trials., (©2014 American Association for Cancer Research.)

- Abstract
Patient navigation is now a standard component of cancer care in many oncology facilities, but a fundamental question for navigator programs, especially in medically underserved populations, is whether or not individuals will use this service. In this study, we evaluated acceptance of a community-based navigator program for cancer control and identified factors having significant independent associations with navigation acceptance in an urban sample of African Americans. Participants were African American men and women ages 50-75 who were residents in an urban metropolitan city who were referred for navigation. Of 240 participants, 76% completed navigation. Age and perceived risk of developing cancer had a significant independent association with navigation acceptance. Participants who believed that they were at high risk for developing cancer had a lower likelihood of completing navigation compared with those who believed that they had a low risk for developing this disease. The likelihood of completing navigation increased with increases in age. None of the socioeconomic factors or health care variables had a significant association with navigation acceptance. There are few barriers to using community-based navigation for cancer control among urban African Americans. Continued efforts are needed to develop and implement community-based programs for cancer control that are easy to use and address the needs of medically underserved populations.

- Abstract
The social environment is important to body mass index and obesity. However, it is unknown if perceptions of the social environment are associated with obesity-related behaviors in populations at greatest risk for being overweight or obese. We evaluated the relationship between collective efficacy and diet and physical activity in a community-based sample of African American adults who were residents in an urban area. Data were collected as part of an academic-community partnership from November 2009 to 2011. We evaluated whether participants met the recommended guidelines for diet and physical activity based on collective efficacy and their sociodemographic background, health care variables, and self-efficacy in a community-based sample of African American adults (n = 338) who were residents in the Philadelphia, PA metropolitan area. Overall, many participants did not meet the recommended guidelines for fruit and vegetable intake or physical activity. The likelihood of meeting the recommended guidelines for fruit intake increased with greater levels of collective efficacy (OR 1.56, 95 % CI 1.18, 2.07, p = 0.002) and self-efficacy for diet (OR 1.56, 95 % CI 1.19, 2.04, p = 0.001). Collective efficacy was not associated with physical activity and the positive association between collective efficacy and vegetable intake was not statistically significant (OR 1.25, 95 % CI 0.94, 1.65, p = 0.12). It is important to determine the most effective methods and settings for improving diet and physical activity behaviors in urban African Americans. Enhancing collective efficacy may be important to improving adherence to recommended guidelines for obesity-related health behaviors.

- Abstract
Low rates of genetic counseling among African American women have generated concerns about disparities; however, to the extent that women's decisions to accept or decline counseling are consistent with their values, then lower participation may reflect preferences and not disparities. We evaluated the extent to which women were satisfied with their decision about participating in genetic counseling for BRCA1/2 mutations and identified variables that were associated significantly with satisfaction. Prospective study of decision satisfaction with 135 African American women who had a minimum 5% prior probability of having a BRCA1/2 mutation. Decision satisfaction was evaluated one month after women were offered participation in genetic counseling using a structured questionnaire. Women were satisfied with their participation decision; more than 80% reported that their decision was consistent with their family values. However, women who declined pre-test counseling had significantly lower satisfaction scores. Our findings highlight the importance ensuring that racial differences that are due to preferences and values are not misclassified as disparities in order to identify and address the root causes of disparate treatment.

- Abstract
Purpose: Understanding genetic factors that contribute to racial differences in cancer outcomes may reduce racial disparities in cancer morbidity and mortality. Achieving this goal will be limited by low rates of African American participation in cancer genetics research., Method: We conducted a qualitative study with African American adults (n = 91) to understand attitudes about participating in cancer genetics research and to identify factors that are considered when making a decision about participating in this type of research., Results: Participants would consider the potential benefits to themselves, family members, and their community when making a decision to participate in cancer genetics research. However, concerns about exploitation, distrust of researchers, and investigators' motives were also important to participation decisions. Individuals would also consider who has access to their personal information and what would happen to these data. Side effects, logistical issues, and the potential to gain knowledge about health issues were also described as important factors in decision making., Conclusion: African Americans may consider a number of ethical, legal, and social issues when making a decision to participate in cancer genetics research. These issues should be addressed as part of recruitment efforts.

- Abstract
Purpose: As the potential role of genetic testing in disease prevention and management grows, so does concern about differences in uptake of genetic testing across social and racial groups. Characteristics of how genetic tests are delivered may influence willingness to undergo testing and, if they affect population subgroups differently, alter disparities in testing., Methods: Conjoint analysis study of the effect of 3 characteristics of genetic test delivery (ie, attributes) on willingness to undergo genetic testing for cancer risk. Data were collected using a random digit dialing survey of 128 African American and 209 white individuals living in the United States. Measures included conjoint scenarios, the Revised Health Care System Distrust Scale (including the values and competence subscales), health insurance coverage, and sociodemographic characteristics. The 3 attributes studied were disclosure of test results to the health insurer, provision of the test by a specialist or primary care doctor, and race-specific or race-neutral marketing., Results: In adjusted analyses, disclosure of test results to insurers, having to get the test from a specialist, and race-specific marketing were all inversely associated with willingness to undergo the genetic test, with the greatest effect for the disclosure attribute. Racial differences in willingness to undergo testing were not statistically significant (P=0.07) and the effect of the attributes on willingness to undergo testing did not vary by patient race. However, the decrease in willingness to undergo testing with insurance disclosure was greater among individuals with high values distrust (P=0.03), and the decrease in willingness to undergo testing from specialist access was smaller among individuals with high competence distrust (P=0.03)., Conclusions: Several potentially modifiable characteristics of how genetic tests are delivered are associated with willingness to undergo testing. The effect of 2 of these characteristics vary according to the level of health care system distrust, suggesting that policy decisions about delivery of genetic testing may influence differences in uptake across patient subgroups defined by levels of distrust rather than by race.

- Abstract
Aims: Scientific agencies rely on individuals to donate their DNA to support research on chronic conditions that disproportionately affect African Americans; however, donation is variable in this population. The purpose of this study was to identify sociodemographic characteristics, health care variables, and cultural values having significant independent associations with intentions to donate blood or saliva samples for cancer genetics research among African American adults., Method: Cross-sectional survey of donation intentions., Results: The majority of respondents (73%) were willing to donate a biological sample for cancer genetics research. The results of the multivariate regression model found that respondents who received care at a facility other than a doctor's office (e.g., community center) were about five times more likely to be willing to donate a sample for cancer genetics research (odds ratio [OR]=5.28, 95% confidence interval [CI]=1.16-24.12, p=0.03); whereas, greater levels of religiosity (OR=0.09, 95% CI=0.01-0.75, p=0.02) and present temporal orientation (OR=0.23, 95% CI=0.06-0.79, p=0.02) were associated with a lower likelihood of donating a sample., Conclusion: Efforts to enhance donation of biological samples for cancer genetics research may need to target diverse clinical sites for recruitment. Additionally, recruitment materials may need to address cultural values related to religiosity and present temporal orientation.

- Abstract
Purpose: Short-term reactions to BRCA1 and BRCA2 (BRCA1/2) genetic test results have been described in several reports, but the long-terms effects of testing have not been examined extensively., Methods: We conducted an observational study to characterize the long-term impact of genetic testing for BRCA1/2 mutations in 167 women who had received genetic test results at least 4 years ago. We also evaluated the relationship between genetic testing-specific reactions and breast and ovarian cancer screening to determine the behavioral significance of adverse reactions., Results: Seventy-four percent of women were not experiencing any distress regarding their test result, 41% were not experiencing any uncertainty, and 51% had a score for positive experiences that was suggestive of low levels of adverse reactions in terms of family support and communication. Mutation carriers (odds ratio, 3.96; 95% CI, 1.44 to 10.89; P = .01) were most likely to experience distress. Only less time since disclosure was related significantly to experiencing uncertainty (odds ratio, 0.62; 95% CI, 0.44 to 0.88; P = .008). In terms of cancer screening, 81% of women had a mammogram during the year before study enrollment, 25% had magnetic resonance imaging (MRI), 20% had a transvaginal ultrasound, and 20% had a CA-125. Experiencing distress was associated significantly with having a CA-125 (χ(2) = 3.89, P = .05), and uncertainty was associated with having an MRI (χ(2) = 8.90, P = .003)., Conclusion: Our findings show that women are not likely to experience genetic testing concerns several years after receiving BRCA1/2 test results; distress and uncertainty are not likely to have adverse effects on screening among women at risk for hereditary disease.

- Abstract
Background: Although colorectal cancer (CRC) is the second leading cause of cancer death among adults in the US and colonoscopy is efficacious in reducing morbidity and mortality from CRC, screening rates are sub-optimal. Understanding the socioeconomic, cultural, and health care context within which decisions about colonoscopy are made allows physicians to address patients' most salient beliefs and values and other constraints when making screening recommendations., Objective: To evaluate the direct and interactive effects of socioeconomics, health care variables, psychological characteristics, and cultural values on colonoscopy use., Design, Setting, Participants: National survey completed between January-August 2009 in a random sample of African American, white, and Hispanic adults ages 50-75 without cancer (n = 582)., Main Measure: Self-reported colonoscopy use., Key Results: Only 59% of respondents reported having a colonoscopy. The likelihood of colonoscopy increased with having health insurance (OR = 2.82, 95% CI = 1.24, 6.43, p = 0.004), and increasing age (OR = 1.40, 95% CI = 1.11, 1.77, p = 0.001). In addition, respondents with greater self-efficacy were more likely to have a colonoscopy (OR = 2.41, 95% CI = 1.35, 4.29, p = 0.003)., Conclusions: Programs that help patients to overcome access and psychological barriers to screening are needed.
