The paper includes a description of the setting for the study, the historical background, establishment of the study, the sample, follow-up rates, changes in sample characteristics over time, the procedures, the data gathered at each phase and the investigators responsible. Some of the topics studied over the years are set out in a table of descriptors which includes references to refereed journal articles that include results relating to the topics. Plans for the future are also described. Reflections on some of the reasons why the study has been successful are noted. The article concludes with a full list of publications and reports (1–328), current as at 1 July 1989.
