How Twin Studies Help Advance Health Research

Twins and multiples are uniquely valuable to research and offer the opportunity to explore the balance between genetics and environment, and its impact on health. Twin studies have contributed to important scientific insights into diabetes, heart disease, obesity, as well as alcohol and tobacco use. Gary Swan explains the findings that have resulted from these studies and the value of twin registries – which rely on identical and fraternal twins.

By joining SRI's Twin Research Registry™, twins have the opportunity to participate in studies and receive periodic newsletters.
