Teenagers with ADHD are more vulnerable to negative outcomes than teenagers without ADHD, in part because they engage in more extreme risk-taking. The goal of this study is to understand how brain development during puberty may contribute to risk-taking behaviors in adolescence, and how this differs in youth with and without ADHD. We also want to learn how to predict which children are more vulnerable to extreme levels of risk-taking when they become teenagers. This study will help us to identify children who may be at risk for negative outcomes so potential problems can be addressed early and ultimately prevented.

The Johnston County Health Study is a long-term research study based in Johnston County, North Carolina. The purpose of the study is to measure how common osteoarthritis, pain, and disability are in the county, as well as its impact on individuals and the community.

In our study, we are examining how osteoarthritis is related to other health conditions, such as injury, obesity, diabetes, and heart disease. We also want to know how osteoarthritis and other health conditions differ by gender and race/ethnicity.
