A joint program of the GIM Division and the Welch Center for Prevention, Epidemiology, and Clinical Research, Johns Hopkins ProHealth is among the nation’s premier centers for clinical trials to prevent cardiovascular disease, diabetes, and kidney disease.  It was established in 1989 by Dr. Paul Whelton, who was also the founding director of the Welch Center.

A decade ago, Dr. Lawrence Appel assumed leadership of ProHealth.  Under his direction, the program grew substantially.  It currently houses six major NIH-funded randomize controlled trials, with a total budget of over $6 million annually.  Located near the intersection of routes 70 and 695 in the Woodlawn section of Baltimore County (directions), the program occupies 15,000 sq ft of space and employs over 40 research staff.  Downstairs, the Data Collection Suite includes a reception area, a clinical laboratory, 6 examination rooms, a large data storage room, and long-term freezers.  Upstairs, the Intervention Suite includes group meeting rooms, individual counseling rooms, an exercise room, and a state of the art metabolic kitchen.

ProHealth has hosted a series of landmark studies, including TOHP, TONE, DASH, DPP, AASK, CRIC, Achieve, and Look AHEAD.  Some of the high-impact papers associated with these studies are available online (coming soon).
