Engaging diverse populations in biospecimen donation: results from the Hoy y Mañana study
Abstract
The disproportionately lower number of certain subpopulations participating in clinical and prevention research has a significant impact on the representativeness of scientific outcomes. The Hoy y Mañana program (Today and Tomorrow) was developed as a culturally and linguistically appropriate education program to engage diverse medically underserved populations without a cancer diagnosis in biospecimen donation for cancer genomic research. Participants were recruited to in-depth community-based educational programs (∼45-60-min duration) or during open events in the community based on a convenience sampling. Programs were offered in English and Spanish. An on-site mobile lab along with phlebotomy services was provided at all programs and events to collect participant biospecimen (blood) samples to be stored at the cancer center's Data Bank and BioRepository (DBBR). The distributions for education, race/ethnicity, and gender were similar across the event types. Most of the participants were women. The analysis sample had a total of 311 participants, including 231 from the education programs and 80 participants from open events. Those with a higher education (college or more) were more likely to donate than those with a lower level of education (high school or less) (45 vs 28 %, p = 0.007). Actual donation status was not associated with age or race. Willingness to donate a biospecimen and biospecimen donation rates followed the same pattern with respect to participants with higher levels of education being more willing to donate and giving a blood donation. Prior to outreach efforts, less than 6 % of specimens donated to DBBR from healthy/non-cancer patients were from minority participants.
