Pennsylvania Twin Registry (PAtwins)

Multiple-birth families are an important resource for researchers interested in investigating how social and genetic influences work together to influence health-related behaviors.

The Pennsylvania Twin Registry (PAtwins) is a database of multiple birth families that are interested in participating in research.

All the information in the database is confidential and all research studies the are based on the registry with be approved by the university's Office of Research Protections prior to potential participants being contracted for specific studies.

Many families find that participating in research is interesting, gives insight into their children's development, and provides an opportunity to contribute to what we know about social and health behaviors. Most research projects will provide financial compensation to participants.

If you are the legal parent or guardian of a multiple birth children (e.g. twins or triplets) between newborn and 18 years of age and are interested in registering your family for the PATwins database, please visit the enrollment page. You will be contacted when a researcher is interested in recruiting you and your family for a research project.
