A comparative effectiveness education trial for lifestyle health behavior change in African Americans.

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.

Neighborhood Satisfaction and Colorectal Cancer Screening in a Community Sample of African Americans.

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.

Acceptance of a community-based navigator program for cancer control among urban African Americans.

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.

Collective efficacy and obesity-related health behaviors in a community sample of African Americans.

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.

Using a mixed-methods approach to identify health concerns in an African American community.

OBJECTIVES: We used qualitative and quantitative data collection methods to identify the health concerns of African American residents in an urban community and analyzed the extent to which there were consistencies across methods in the concerns identified. METHODS: We completed 9 focus groups with 51 residents, 27 key informant interviews, and 201 community health surveys with a random sample of community residents to identify the health issues participants considered of greatest importance. We then compared the issues identified through these methods. RESULTS: Focus group participants and key informants gave priority to cancer and cardiovascular diseases, but most respondents in the community health survey indicated that sexually transmitted diseases, substance abuse, and obesity were conditions in need of intervention. How respondents ranked their concerns varied in the qualitative versus the quantitative methods. CONCLUSIONS: Using qualitative and quantitative approaches simultaneously is useful in determining community health concerns. Although quantitative approaches yield concrete evidence of community needs, qualitative approaches provide a context for how these issues can be addressed. Researchers should develop creative ways to address multiple issues that arise when using a mixed-methods approach.

Sociocultural determinants of men's reactions to prostate cancer diagnosis.

OBJECTIVE: To develop a better understanding of how men react to being diagnosed with prostate cancer and identify factors that influence these responses, we conducted an observational study to identify sociocultural predictors of men's psychological reactions. METHODS: Participants were 70 African American and 124 white prostate cancer patients who completed a structured telephone interview that evaluated psychological reactions in terms of intrusive thoughts about cancer and attempts to avoid cancer-related thoughts and feelings. Perceptions of disease-specific stress, cultural beliefs and values, and social constraints were also assessed during the interview. RESULTS: There were no racial differences in men's reactions to being diagnosed with prostate cancer; however, greater perceptions of disease-specific stress, increasing levels of present temporal orientation, and more social constraints had significant positive effects on avoidant reactions. Greater perceptions of stress also had a significant positive effect on intrusive thoughts. CONCLUSIONS: The results of this study highlight the need for individualized approaches to help men address their thoughts and feelings about being diagnosed with prostate cancer. These efforts should include strategies that help men to communicate more effectively with social support resources and address cultural beliefs and values related to temporal orientation.

Participation rates and representativeness of African Americans recruited to a health promotion program.

When using community-based participatory methods to develop health promotion programs for specific communities, it is important to determine if participation differs based on sociodemographics and the extent to which program participants are demographically representative of the target community, especially when non-random recruitment methods are used. We evaluated rates of participating in a health promotion program among African American residents in an urban community and determined if program participants were representative of community residents in terms of sociodemographic factors. While participation in the program was modest, participation did not differ based on psychological factors or body mass index. However, individuals who were unemployed were significantly more likely to participate in the program compared with those who were employed. Our sample included a greater proportion of individuals who only had a high school education compared with community residents but was similar to community residents in terms of gender, marital status and employment.

Effects of integrated risk counseling for cancer and cardiovascular disease in African Americans.

OBJECTIVE: We evaluated a risk counseling intervention designed to enhance understanding about risk factors for cancer and cardiovascular disease, to improve self-efficacy for diet and physical activity, and to increase intentions to eat healthier and be physically active. METHODS: We conducted a quasi-experimental study developed by academic investigators and community stakeholders to evaluate the effects of integrated risk counseling in a community-based sample of African American adults (n = 101). The intervention provided education about the overlap in risk factors for cancer and cardiovascular disease and included components from motivational interviewing. RESULTS: Changes in behavioral intentions were not statistically significant (p > .05). Participants reported significantly greater levels of self-efficacy for diet (t = 2.25, p = .03) and physical activity (t = 2.55, p = .01), and significantly increased perceived risks of developing colon cancer (chi2 = 3.86, p = .05) and having a heart attack (chi2 = 4.50, p = .03). CONCLUSIONS: Integrated risk counseling may have some benefits among African Americans.

Lessons Learned from the Medical University of South Carolina Transdisciplinary Collaborative Center (TCC) in Precision Medicine and Minority Men's Health.

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.

Discordance in perceived risk and epidemiological outcomes of prostate cancer among African American men.

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.

Ever and Annual Use of Prostate Cancer Screening in African American Men.

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.

Perceived Efficacy and Control for Neighborhood Change: the Cross-Cutting Role of Collective Efficacy.

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.

Preparing African-American men in community primary care practices to decide whether or not to have prostate cancer screening.

BACKGROUND: This study was a randomized trial to test the impact of an informed decision-making intervention on prostate cancer screening use. METHODS: The study population included 242 African-American men from three primary care practices who were 40-69 years of age and had no history of prostate cancer. Participants completed a baseline survey questionnaire and were randomly assigned either to a Standard Intervention (SI) group (N=121) or an Enhanced Intervention (EI) group (N=121). An informational booklet was mailed to both groups. EI group men were also offered a screening decision education session. Two outcomes were considered: (1) complete screening (i.e., having a digital rectal exam (DRE) and prostate specific antigen (PSA) testing), and (2) complete or partial screening (i.e., having a PSA test with or without DRE). An endpoint chart audit was performed six months after initial intervention contact. The data were analyzed via exact logistic regression. RESULTS: Overall, screening use was low among study participants. EI group men had a screening frequency two times greater than that of SI group men, but the difference was not statistically significant: 8% vs. 4 % (OR = 1.94) fo rcomplete screening, and 19% vs. 10% (OR = 2.08) for complete or partial screening. Multivariable analyses showed that being in the EI group and primary care practice were significant predictors of complete or partial screening (OR = 3.9 and OR = 5.64, respectively). CONCLUSION: Prostate cancer screening use may be influenced by exposure to decision education and the influence of screening-related primary care practice factors.

Developing a Cookbook with Lifestyle Tips: A Community-Engaged Approach to Promoting Diet-Related Cancer Prevention Guidelines.

Supplementing nutrition education with skills-building activities may enhance community awareness of diet-related cancer prevention guidelines. To develop a cookbook with lifestyle tips, recipes were solicited from the National Black Leadership Initiative on Cancer (NBLIC) community coalitions and dietary intake advice from participants in the Educational Program to Increase Colorectal Cancer Screening (EPICS). With guidance from a chef and registered dietitian, recipes were tested, assessed, and transformed; lifestyle advice was obtained from focus groups. The cookbook with lifestyle tips, named "Down Home Healthy Living (DHHL) 2.0," was distributed in print form to 2,500 EPICS participants and shared electronically through websites and social media.

Intervention completion rates among African Americans in a randomized effectiveness trial for diet and physical activity changes.

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.

The 4th Bi-annual international African-Caribbean Cancer Consortium conference: building capacity to address cancer health disparities in populations of African descent.

This is a brief summary of the 4(th) International Meeting of the African-Caribbean Cancer Consortium (AC3), organized and sponsored by Fox Chase Cancer Center (FCCC), and held on July 21-22, 2012 at the Lincoln University Graduate Center, Lincoln Plaza, Philadelphia, Pennsylvania. AC3 investigators gathered in Philadelphia, PA to present the results of our ongoing collaborative research efforts throughout the African Diaspora. The general theme addressed cancer health disparities and presentations represented all cancer types. However, there was particular emphasis on women's cancers, related to human papillomavirus (HPV) and human immunodeficiency virus (HIV) infections.

Racial differences in quality of life following prostate cancer diagnosis.

OBJECTIVES: To evaluate the effects of race on QOL while adjusting for subjective stress and religiosity among African American and white prostate cancer patients. Although racial differences in quality of life (QOL) have been examined between African American and white prostate cancer patients, it is not known whether differences exist while adjusting for psychological and cultural factors. We predicted that African American men would report poorer emotional and physical functioning after adjusting for these factors and that greater subjective stress and lower levels of religiosity would be associated with poorer well-being. METHODS: We conducted an observational study of QOL among 194 African American and white men who were recruited from February 2003 through March 2008. RESULTS: Race had a significant effect on emotional functioning after adjusting for perceptions of stress and religiosity. Compared with white men, African American men (P = .03) reported significantly greater emotional well-being. Greater subjective stress was associated significantly with poorer emotional functioning (P = .0001) and physical well-being (P = .0001). There were no racial differences in physical functioning (P = .76). CONCLUSIONS: The results of this study highlight the importance of developing a better understanding of the context within which racial differences in QOL occur and translating this information into support programs for prostate cancer survivors.

Racial differences in medical mistrust among men diagnosed with prostate cancer.

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.

Community-academic partnerships: lessons learned from replicating a salon-based health education and promotion program.

BACKGROUND: We present a model of a community-academic partnership formed to replicate a unique salon-based health education and promotion program among African-American and Latino communities in Philadelphia. OBJECTIVES: The purpose of this article is to describe the partnership principles established and lessons learned in replicating the salon-based program that sought to develop a cadre of community-academic partners and build community-based organizations' (CBOs) capacity to implement and evaluate the program. METHODS: As the lead organization, the Arthur Ashe Institute for Urban Health (AAIUH), formed a partnership with two CBOs, three universities, and 17 salons. Guiding principles were established to manage the large collaborative and ensure success. LESSONS LEARNED: By embracing a common mission and principles of understanding, co-learning, building capacity and sharing responsibility and recognition, this partnership was able to achieve positive outcomes. Challenges faced were related to replication, CBO infrastructure, data management capacity, and other process issues. CONCLUSIONS: Despite challenges, we created and sustained an enduring partnership and brought positive change to the community. Lessons learned highlight issues to examine before furthering this work such as fostering trust and building meaningful relationships.

Differences in cultural beliefs and values among African American and European American men with prostate cancer.

BACKGROUND: Although cultural values are increasingly being recognized as important determinants of psychological and behavioral outcomes following cancer diagnosis and treatment, empirical data are not available on cultural values among men. This study evaluated differences in cultural values related to religiosity, temporal orientation, and collectivism among African American and European American men. METHODS: Participants were 119 African American and European American men who were newly diagnosed with early-stage and locally advanced prostate cancer. Cultural values were evaluated by self-report using standardized instruments during a structured telephone interview. RESULTS: After controlling for sociodemographic characteristics, African American men reported significantly greater levels of religiosity (Beta = 24.44, P < .001) compared with European American men. African American men (Beta = 6.30, P < .01) also reported significantly greater levels of future temporal orientation. In addition, men with more aggressive disease (eg, higher Gleason scores) (Beta = 5.11, P < .01) and those who were pending treatment (Beta = -6.42, P < .01) reported significantly greater levels of future temporal orientation. CONCLUSIONS: These findings demonstrate that while ethnicity is associated with some cultural values, clinical experiences with prostate cancer may also be important. This underscores the importance of evaluating the effects of both ethnicity and clinical factors in research on the influence of cultural values on cancer prevention and control.
