Engaging African Americans in Research: The Recruiter's Perspective.

Purpose: To examine barriers recruiters encounter when enrolling African American study participants, identify motivating factors to increase research participation, and provide recommendations to facilitate successful minority recruitment. Background: Recruiters are often the first point of contact between the research study and potential African American participants. While challenges in enrolling African Americans into clinical and epidemiologic research has been reported in numerous studies the non-physician recruiter's role as a determinant of overall participation rates has received minimal attention. Methods: We conducted four 90-minute teleconference focus groups with 18 recruiters experienced in enrolling African Americans for clinical and epidemiologic studies at five academic/medical institutions. Participants represented diverse racial and ethnic backgrounds and were asked to reflect on barriers preventing African Americans from participating in research studies, factors that motivated participation, and recommendations to increase participation of African Americans in research. Multi-coder and thematic data analysis was implemented using the Braun and Clarke method. Results: Prominent concerns in recruitment of African Americans in research include fear and mistrust and inflexible research protocols. The participants suggest that improved recruitment could be achieved through cross-cultural and skillset building training opportunities for recruiters, greater community engagement among researchers, and better engagement with clinic staff and research teams.

Depression inhibits the anti-inflammatory effects of leisure time physical activity and light to moderate alcohol consumption.

Light to moderate alcohol consumption and leisure time physical activity (LTPA) are independently associated with lower levels of high sensitivity C-reactive protein (CRP), a predictor of cardiometabolic risk. In contrast, depression, ranging from low mood disturbance to major depressive disorder, has been associated with elevated CRP. To test the hypothesis that depression attenuates the anti-inflammatory effects of LTPA and alcohol consumption, the current study tested the moderating effect of severity of depressive symptomatology on the relation of alcohol consumption and LTPA to CRP in 222 healthy adult men and women (18-65 years of age). Given the known effects of gender on inflammation, we also examined the effects of gender on the tested interactions. Depression was assessed using the Beck Depression Inventory. Frequency of alcohol consumption, hours of LTPA per week and other coronary risk/protective factors were assessed via self-report and structured interview. Fasting blood samples were used to measure CRP and lipids. As predicted, the interaction between LTPA and depressive symptomatology was significant (F=5.29, p<.03) such that lower CRP was associated with the combination of decreased depressive symptomatology and increased LTPA. Among those with increased depressive symptoms, increased LTPA was not associated with higher CRP. Similarly, depression interacted with alcohol consumption in predicting CRP in men but not women (F=5.03, p<.008) such that for men light to moderate alcohol consumption was associated with lower CRP but only among those with decreased depressive symptoms. Light to moderate alcohol consumption was not associated with lower CRP in those with increased depressive symptom severity. The pattern of the interactions between anti-inflammatory activities such as light to moderate alcohol consumption and LTPA and psychological distress as indexed by severity of depressive symptomatology suggests an important new avenue for future research.
