Midwestern African American Twin Study of Aging (MAATSA), a part of the Multi-Ethnic Twin Registry (MTR) @ the University of Minnesota

In coordination with the University of Minnesota, Purdue University is seeking African American/Black twins who are 18+ to participate in a brief data collection survey to determine eligibility for future work. Only one member of the twin is needed to participate, though both can! Participation is expected to take no more than 5 minutes to complete and respondents are entered into a raffle to earn a $15 gift card of their choice.

This study is part of long-standing work conducted by the University of Minnesota. See this link for more information on previous work done by this research group.
