Participant Recruitment of African American College Students at an Historically Black College and University (HBCU): Challenges and Strategies for Health-Related Research

Lack of research participation among African Americans is problematic for population relevant health disparity research. The purpose of this paper is to identify and describe challenges and strategies in recruitment of African American college students for health related research being conducted at a small Historically Black College or University (HBCU). Upon completion of a recruitment and retention literature review, study investigators constructed and tested a culturally-specific, direct-appeal protocol to recruit participants. Major barriers to recruitment of African American college students included discrete sources of distrust, lack of understanding of the research process, and logistical concerns. Implementation of a culturally-specific, direct appeal protocol led to a significant improvement in recruitment and retention of student participants. It is imperative that researchers demystify scientific investigation as a first step towards building trust between themselves and target populations, particularly those from traditionally underrepresented groups. Reasons for distrust, a need for trust and trust building strategies are offered here

Prehypertensive Risk Among African-American Undergraduates: Do The Extra Pounds Really Matter?

The objective of this study is to examine prehypertension among young African American adults and evaluate the predictive value of easily obtained standard measures of adiposity. Data for this study of 155 primarily African-American undergraduates was collected between April 2010-11. Participants provided family health history and anthropometric measures, including body weight, body mass index (BMI), and waist to hip (WHR) ratio. Percentages were calculated for demographics. The average systolic blood pressure measured over two time periods within a single semester generated prehypertension rates. Univariate and multivariate logistic regression examined the impact of BMI, WHR, weight, and family medical history on prehypertension. A majority of participants (64%) were prehypertensive. Logistic regressions suggest that weight-related measures better predicted prehypertension than family history or WHR. In conclusion, this study showed prehypertensive risk was a significant problem among, young and primarily African-American adults. Furthermore, the best adiposity measure was weight, even when controlling for family history, WHR, and BMI
