Health professionals tested teenagers for diseases such HIV, high blood pressure and diabetes.
Organizers said their goal was to prevent problems before they began.
"If we can get our students to be more health conscious as young people, then they'll grow into healthier adults, and in turn, we'll have healthier communities. A lot of the things that we do as a community are things that we learned from those who came before us, said Magic Executive Director Bryan Echols.
Organizers expected as many as 2,000 teenagers to attend Saturday's event.
