Evolution of the Pittsburgh studies of the epidemiology of insulin-dependent diabetes mellitus. Pittsburgh Diabetes Epidemiology and Etiology Research Group

Abstract

The Pittsburgh project evaluating the epidemiology and etiology of insulin-dependent diabetes mellitus (IDDM) is currently one of the large ongoing studies of childhood diabetes. This paper traces the evolution of the project, from the initial basic epidemiologic approach in the early 1980s, to the current thrust where complex molecular genetic approaches are being incorporated into population-based research. The epidemiology models employed in the Pittsburgh project are similar to those that could be used in many areas of chronic disease research. The integration of immunogenetics into epidemiology produces a powerful approach for understanding the complex interaction of host susceptibility and environmental agents that contribute to the development of IDDM.
