NCT07657221

Brief Summary

The goal of this study is to examine the effects of providing personalized information about behavioral, physical, and genetic factors that are associated with elevations in risk for some health problems. The main research question is: can we affect young adult behaviors through communication about these health-related risks? Participants will be asked to complete an in-person baseline session where they provide a DNA sample, complete online surveys, and do a brief interview. They will then receive one of several brief online information sessions and be followed in online surveys approximately every 3 months over the next 2 years.
