Carolina African American Twin Study of Aging (CAATSA)
The major objective of the Carolina African American Twin Study of Aging is to identify the proportion of the genetic and environmental sources of individual variation in measures of health and behavioural factors in a sample of adult African Americans. Drawn from birth records from the State of North Carolina, United States, this in-person study used public records to identify a cohort of twins between 22 and 92 years of age (mean age of 49.82 years), 39.7% of which were men. Members of non-intact twin pairs and siblings were also recruited to explore alternative models to the classic twin design.
