Creating a Diverse Cohort for Longitudinal Aging Research

Background

Enrolling participants from underrepresented ethnoracial groups in aging research remains a persistent challenge. University of Pittsburgh researchers tested an intensive community engagement approach that combined multiple recruitment strategies to recruit a diverse sample of older adults from a small-town area into a longitudinal aging study.

Findings

Over four years, a steady trickle of individuals signed up for study information, including 66% who self-identified as Black. The share of people who eventually enrolled increased each year, from 68% to 94%. Community events, word-of-mouth referrals, and mailed postcards yielded the most contacts.
