Between 1970 and 1973, all men born between 1920 and 1924 and resident in the municipality of Uppsala, Sweden, were invited to participate in a health survey.
Data Collection Event
Participants in the first survey were invited to the second investigation. The investigation procedures were similar to that at age 50. All participants underwent a minor investigation including measurement of fasting blood glucose, blood pressure, weight and height, and a medical questionnaire. A subpopulation was selected for further investigations including an intravenous glucose tolerance test.
