Recruiting underrepresented groups into the Carbohydrates and Related Biomarkers (CARB) cancer prevention feeding study

Using data from a randomized, controlled feeding study, which aimed to recruit 88 participants (including 22 Hispanics and 22 African Americans), we examined strategies for recruiting individuals from underrepresented groups into research trials. Study eligibility criteria included participants who 1) were 18-45 years old; 2) had a body mass index (BMI) >18<24.9 or BMI>28.0 <40.0; 3); had no preexisting health conditions; 4) were non-smoking; 5) had normal fasting blood glucose level (<100 mg/dL); and 6) spoke English. Participants were recruited using two overarching methods: media-based strategies (flyers and posters, email announcements, announcements in local and campus newspapers, and the Internet) and in-person strategies (presentations in university classes and community events). Participants were enrolled March 2006-March 2009. We present the numbers of individuals requesting study information, completing pre-enrollment screening questionnaires, and enrolling in the study. A total of 1036 individuals requested study information, and 396 completed a pre-enrollment screening questionnaire; 90 enrolled in the study (22 Hispanics and 18 African Americans). Among enrolled participants, in-person recruitment strategies were reported by 39% of African Americans, 73% of Hispanics, and 30% of non-Hispanic Whites (P<0.001). In-person recruitment strategies were successful among Hispanics. Mass media recruitment strategies were successful among non-Hispanic Whites but enlisted relatively few Hispanic participants. Both strategies recruited nearly equal percentages of African Americans. These data suggest that different strategies are needed to effectively recruit racial/ethnic population subgroups into intervention studies.

A small grants program to involve communities in research

A key tenet of community-based participatory research is that communities be involved in all facets of research, from defining the problem to identifying solutions, to assisting in the research, and to participating in the publication of results. In this study, we instituted a small grants program for community participation. A Request for Applications (RFA) was developed and circulated widely throughout the Valley. The RFA sought proposals to address health disparities in cancer education, prevention, and treatment among Hispanics living in the Valley. Funds available were $2,500.00-3,500.00 for 1 year's worth of work. To help evaluate the progress of the RFA community projects according to the perspectives of the Community Advisory Board (CAB), an open-ended, semi-structured interview was created and administered by a former staff member to CAB members. In 4 years, ten small grants proposed by community members were funded. Funds allocated totaled approximately $25,000. Interviews with CAB members indicated that the RFA program was perceived positively, but there were concerns about sustainability. Our community grants program resulted in the implementation of several novel cancer prevention programs conducted by a variety of community organizations in the Lower Yakima Valley.
