Community recruitment of underrepresented populations to the AHEAD 3-45 preclinical AD trial using novel partnerships with nursing and community-based organizations: Lessons and outcomes.

ABSTRACT

INTRODUCTION: Alzheimer's disease (AD) disproportionately affects minoritized populations who remain underrepresented in AD trials. METHODS: We partnered with local nursing community-based organizations to implement a culturally tailored educational intervention and recruit Hispanic/Latino American, Filipino American, and Korean American adults aged 55 to 80 for the AHEAD study, a preclinical AD trial, at the University of California, Irvine. RESULTS: We engaged 654 individuals across 21 events, leading to 71 prescreenings 21.1% Filipino, 11.2% Hispanic/Latino, and 67.6% Korean adults. Ineligibility due to age and language barriers was common among Hispanic/Latino and Korean adults, respectively. Filipino adults often withdrew interest or were lost to follow-up. Ultimately, 25 participants enrolled eight Filipino, two Hispanic/Latino, and 15 Korean adults. Tailored, culturally relevant content significantly contributed to the engagement success. DISCUSSION: This study demonstrates the value and impact of novel partnerships with health-related provider organizations that provide trusted care and access to underrepresented communities. HIGHLIGHTS Six hundred and fifty four underrepresented individuals were reached, and 25 enrolled in the AHEAD 3-45 trial. Twenty-one community events were held via partnerships with nursing and community organizations. The study engaged 21% Filipino, 11% Hispanic/Latino, 68% Korean adults. Community-Based Participatory Research (CBPR) principles enhanced the recruitment process. Transparent communication and joint planning were key.
