Abstract

Black/African American seniors experience disproportionately higher incidence of morbidity and mortality related to chronic diseases. They also have reduced access to health care and lower rates of early treatment. Clinical trials benefit black seniors by validating the efficacy of interventions for their population as well as provide individual-level advantages by acting as an alternative access point to health care. Currently, black seniors are significantly underrepresented in clinical research compared to white seniors. This study examined individual and interpersonal levels of the social ecological model, including sociodemographics, functional impairment, and social support to determine which factors influenced the likelihood of joining a clinical trial in the next six months among a sample of black church-going adults over the age of 50. Results from multiple logistic regression models demonstrated that higher degrees of three components of functional impairment, Basic Abilities, Errand Transportation, and Social Abilities were associated with lower likelihood of joining a clinical trial. An interaction between age and Crisis Support was also significant indicating that older adults with higher levels of crisis support were more likely to join clinical trials. Implications for these results indicate that clinical trials should consider the basic abilities and disabilities of their potential participants in recruitment and enrollment efforts and should utilize novel venues such as nursing homes, hospitals, and other senior communities to access this population. In addition, special attention should be paid to adults over 65 as they may require more intensive support from their peers in order to participate in trials.
