The National Institutes of Health has called Add Health “a national treasure” for the scientific community and one of the most important studies of health in the United States.

You were part of the Add Health Study nearly 25 years ago when it began and you cannot be replaced!

Add Health has completed the fifth round of surveys and the Wave V web survey is now closed.  We’ll be in touch in the near future with the next Add Health Newsletter to let you know about study updates.  Please remember to keep your contact information up to date so we can reach you with the newsletters and also let you know about future survey opportunities: Visit this webpage to update your contact information. Having you continue to be part of Add Health is critical for the success of the study.
