The Deep South Network for cancer control. Building a community infrastructure to reduce cancer health disparities.

Given the recent advances in cancer treatment, cancer disparity between whites and African‐Americans continues as an unacceptable health problem. African‐Americans face a considerable disparity with regard to cancer incidence, survival, and mortality when compared with the majority white population. On the basis of prior research findings, the Deep South Network (DSN) chose to address cancer disparities by using the Community Health Advisor (CHA) model, the Empowerment Theory developed by Paulo Freire, and the Community Development Theory to build a community and coalition infrastructure. The CHA model and empowerment theory were used to develop a motivated volunteer, grassroots community infrastructure of Community Health Advisors as Research Partners (CHARPs), while the coalition‐building model was used to build partnerships within communities and at a statewide level. With 883 volunteers trained as CHARPs spreading cancer awareness messages, both African‐Americans and whites showed an increase in breast and cervical cancer screening utilization in Mississippi and Alabama. In Mississippi, taking into account the increase for the state as a whole, the proportion that might be attributable to the CHARP intervention was 23% of the increase in pap smears and 117% of the increase in mammograms. The DSN has been effective in raising cancer awareness, improving both education and outreach to its target populations, and increasing the use of cancer screening services. The National Cancer Institute has funded the Network for an additional 5 years. The goal of eliminating cancer health disparities will be pursued in the targeted rural and urban counties in Mississippi and Alabama using Community‐Based Participatory Research. Cancer 2006.

The Deep South Network for Cancer Control - Eliminating Cancer Disparities Through Community-Academic Collaboration

African Americans have a substantially increased mortality rate compared to Whites in many cancers, including breast and cervix. The Deep South Network for Cancer Control (the Network) was established to develop sustainable community infrastructure to promote cancer awareness, enhance participation of African Americans and other special populations in clinical trials, recruit and train minority investigators, and develop and test innovative community-based cancer control measures to eliminate cancer mortality disparities in special populations. This article describes the steps necessary to form the network and the process and activities required to establish it as an effective infrastructure for eliminating disparities between Whites and African Americans in the United States.

Rural v. urban aspects of cancer: first-year data from the Mississippi Central Cancer Registry.

This study investigated various aspects of cancer between rural and urban localities. The Mississippi State Department of Health Central Cancer Registry received reports of 9,685 new cancer cases in 1996 while there were 5,732 cancer deaths. Even though no difference was found between rural and urban age-adjusted cancer incidence (and mortality), for the vast majority of results, there was a significant difference between rural and urban residents for stage of disease at initial diagnosis. Results also show that the proportion of tumors unstaged at diagnosis is greater for rural compared to urban residents. While this study has limitations, findings suggest that rural residents in Mississippi and rural African American women in particular, have less access to, or utilization of, early cancer detection programs and/or quality medical care.

Telehealth Personalized Cancer Risk Communication to Motivate Colonoscopy in Relatives of Patients With Colorectal Cancer: The Family CARE Randomized Controlled Trial

PURPOSE The rate of adherence to regular colonoscopy screening in individuals at increased familial risk of colorectal cancer (CRC) is suboptimal, especially among rural and other geographically underserved populations. Remote interventions may overcome geographic and system-level barriers. We compared the efficacy of a telehealth-based personalized risk assessment and communication intervention with a mailed educational brochure for improving colonoscopy screening among at-risk relatives of patients with CRC. METHODS Eligible individuals age 30 to 74 years who were not up-to-date with risk-appropriate screening and were not candidates for genetic testing were recruited after contacting patients with CRC or their next of kin in five states. Enrollees were randomly assigned as family units to either an active, personalized intervention that incorporated evidence-based risk communication and behavior change techniques, or a mailed educational brochure. The primary outcome was medically verified colonoscopy within 9 months of the intervention. RESULTS Of the 481 eligible and randomly assigned at-risk relatives, 79.8% completed the outcome assessments within 9 months; 35.4% of those in the personalized intervention group and 15.7% of those in the comparison group obtained a colonoscopy. In an intent-to-treat analysis, the telehealth group was almost three times as likely to get screened as the low-intensity comparison group (odds ratio, 2.83; 95% CI, 1.87 to 4.28; P < .001). Persons residing in rural areas and those with lower incomes benefitted at the same level as did urban residents. CONCLUSION Remote personalized interventions that consider family history and incorporate evidence-based risk communication and behavior change strategies may promote risk-appropriate screening in close relatives of patients with CRC.

Examining the challenges of family recruitment to behavioral intervention trials: factors associated with participation and enrollment in a multi-state colonoscopy intervention trial

BackgroundColonoscopy is one of the most effective methods of cancer prevention and detection, particularly for individuals with familial risk. Recruitment of family members to behavioral intervention trials remains uniquely challenging, owing to the intensive process required to identify and contact them. Recruiting at-risk family members involves contacting the original cancer cases and asking them to provide information about their at-risk relatives, who must then be contacted for study enrollment. Though this recruitment strategy is common in family trials, few studies have compared influences of patient and relative participation to nonparticipation. Furthermore, although use of cancer registries to identify initial cases has increased, to our knowledge no study has examined the relationship between registries and family recruitment outcomes.MethodsThis study assessed predictors of case participation and relative enrollment in a recruitment process that utilized state cancer registries. Participation characteristics were analyzed with separate multivariable logistic regressions in three stages: (1) cancer registry-contacted colorectal cancer (CRC) cases who agreed to study contact; (2) study-contacted CRC cases who provided at-risk relative information; and (3) at-risk relatives contacted for intervention participation.ResultsCancer registry source was predictive of participation for both CRC cases and relatives, though relative associations (odds ratios) varied across registries. Cases were less likely to participate if they were Hispanic or nonwhite, and were more likely to participate if they were female or younger than 50 at cancer diagnosis. At-risk relatives were more likely to participate if they were from Utah, if another family member was also participating in the study, or if they had previously had a colonoscopy. The number of eligible cases who had to be contacted to enroll one eligible relative varied widely by registry, from 7 to 81.ConclusionsFamily recruitment utilizing cancer registry-identified cancer cases is feasible, but highly dependent on both the strategies and protocols of those who are recruiting and on participant characteristics such as sex, race, or geography. Devising comprehensive recruitment protocols that specifically target those less likely to enroll may help future research meet recruitment goals.Trial registrationFamily Colorectal Cancer Awareness and Risk Education Project NCT01274143.

Psychosocial Factors Are Associated With Blood Pressure Progression Among African Americans in the Jackson Heart Study.

BACKGROUND Research that examines the associations of psychosocial factors with incident hypertension among African Americans (AA) is limited. Using Jackson Heart Study (JHS) data, we examined associations of negative affect and stress with incident hypertension and blood pressure (BP) progression among AA. METHODS Our sample consisted of 1,656 normotensive participants at baseline (2000-2004) (mean age 47±12; 61% women). We investigated associations of negative affect (cynical distrust, anger-in, anger-out, and depressive symptoms) and stress (perceived stress, weekly stress inventory (WSI)-event, WSI-impact, and major life events) with BP progression (an increase by one BP stage as defined by JNC VII) and incident hypertension by examination 2 (2005-2008). Poisson regression analysis was utilized to examine the prevalence ratios (PRs; 95% confidence interval (CI)) of BP tracking and incident hypertension with psychosocial factors, adjusting for baseline age, sex, socioeconomic status (SES), and hypertension risk factors. RESULTS Fifty-six percentage of the sample (922 cases) had BP progression from 2005 to 2008. After adjustment for age, sex, and SES, a high anger-out score was associated with a 20% increased risk of BP progression compared to a low anger-out score (PR 1.20; 95% CI 1.05-1.36). High depressive symptoms score was associated with BP progression in the age, sex, and SES-adjusted model (PR 1.14; 95% CI 1.00-1.30). High WSI-event scores were associated with BP progression in the fully adjusted model (PR 1.21; 95% CI 1.04-1.40). We did not observe significant associations with any of the psychosocial measures and incident hypertension. CONCLUSIONS Psychosocial factors were associated with BP progression, with the strongest evidence for number of stressful events that occurred.

Recruitment of rural physicians in a diabetes internet intervention study: overcoming challenges and barriers.

PURPOSE This paper highlights a descriptive study of the challenges and lessons learned in the recruitment of rural primary care physicians into a randomized clinical trial using an Internet-based approach. METHODS A multidisciplinary/multi-institutional research team used a multilayered recruitment approach, including generalized mailings and personalized strategies such as personal office visits, letters, and faxes to specific contacts. Continuous assessment of recruitment strategies was used throughout study in order to readjust strategies that were not successful. RESULTS We recruited 205 primary care physicians from 11 states. The 205 lead physicians who enrolled in the study were randomized, and the overall recruitment yield was 1.8% (205/11231). In addition, 8 physicians from the same practices participated and 12 nonphysicians participated. The earlier participants logged on to the study Web site, the greater yield of participation. Most of the study participants had logged on within 10 weeks of the study. CONCLUSION Despite successful recruitment, the 2 major challenges in recruitment in this study included defining a standardized definition of rurality and the high cost of chart abstractions. Because many of the patients of study recruits were African American, the potential implications of this study on the field of health disparities in diabetes are important.

Efficacy of a Telehealth Intervention on Colonoscopy Uptake When Cost Is a Barrier: The Family CARE Cluster Randomized Controlled Trial.

Background: We tested the efficacy of a remote tailored intervention Tele-Cancer Risk Assessment and Evaluation (TeleCARE) compared with a mailed educational brochure for improving colonoscopy uptake among at-risk relatives of colorectal cancer patients and examined subgroup differences based on participant reported cost barriers. Methods: Family members of colorectal cancer patients who were not up-to-date with colonoscopy were randomly assigned as family units to TeleCARE (N = 232) or an educational brochure (N = 249). At the 9-month follow-up, a cost resource letter listing resources for free or reduced-cost colonoscopy was mailed to participants who had reported cost barriers and remained nonadherent. Rates of medically verified colonoscopy at the 15-month follow-up were compared on the basis of group assignment and within group stratification by cost barriers. Results: In intent-to-treat analysis, 42.7% of participants in TeleCARE and 24.1% of participants in the educational brochure group had a medically verified colonoscopy [OR, 2.37; 95% confidence interval (CI) 1.59–3.52]. Cost was identified as a barrier in both groups (TeleCARE = 62.5%; educational brochure = 57.0%). When cost was not a barrier, the TeleCARE group was almost four times as likely as the comparison to have a colonoscopy (OR, 3.66; 95% CI, 1.85–7.24). The intervention was efficacious among those who reported cost barriers; the TeleCARE group was nearly twice as likely to have a colonoscopy (OR, 1.99; 95% CI, 1.12–3.52). Conclusions: TeleCARE increased colonoscopy regardless of cost barriers. Impact: Remote interventions may bolster screening colonoscopy regardless of cost barriers and be more efficacious when cost barriers are absent.

Bringing Community and Academic Scholars Together to Facilitate and Conduct Authentic Community Based Participatory Research: Project UNITED

Cultural competency, trust, and research literacy can affect the planning and implementation of sustainable community-based participatory research (CBPR). The purpose of this manuscript is to highlight: (1) the development of a CBPR pilot grant request for application; and (2) a comprehensive program supporting CBPR obesity-related grant proposals facilitated by activities designed to promote scholarly collaborations between academic researchers and the community. After a competitive application process, academic researchers and non-academic community leaders were selected to participate in activities where the final culminating project was the submission of a collaborative obesity-related CBPR grant application. Teams were comprised of a mix of academic researchers and non-academic community leaders, and each team submitted an application addressing obesity-disparities among rural predominantly African American communities in the US Deep South. Among four collaborative teams, three (75%) successfully submitted a grant application to fund an intervention addressing rural and minority obesity disparities. Among the three submitted grant applications, one was successfully funded by an internal CBPR grant, and another was funded by an institutional seed funding grant. Preliminary findings suggest that the collaborative activities were successful in developing productive scholarly relationships between researchers and community leaders. Future research will seek to understand the full-context of our findings.

Effectiveness of the extended parallel process model in promoting colorectal cancer screening

Relatives of colorectal cancer (CRC) patients are at increased risk for the disease, yet screening rates still remain low. Guided by the Extended Parallel Process Model, we examined the impact of a personalized, remote risk communication intervention on behavioral intention and colonoscopy uptake in relatives of CRC patients, assessing the original additive model and an alternative model in which each theoretical construct contributes uniquely.
