At baseline, comprehensive clinical and biochemical data, as well as data from questionnaires and interviews were collected. An extensive, self-administered questionnaire with detailed information on socio-demographic variables, lifestyle (smoking, physical activity, alcohol drinking and food habits) and health were usually completed before a general health examination. In addition, socio-psychiatric interviews were performed and mental vulnerability were measured using a Danish questionnaire.

Blood pressure was measured according to the WHO guidelines, and anthropometric measurements included at least weight and height. Vital capacity was measured with spirometry test, and cardio-respiratory fitness as aerobic capacity (V0-max) with a sub-maximal bicycle ergometer or step test. Further, electrocardiography and ultrasonography were performed.

In addition, fasting blood samples and urine samples were drawn.

All cohorts have been followed by registry linkages to the Civil Registration System, Cause of Death Registry, the National Patient Registry, the Psychiatric Central Registry and the Cancer Registry. Social data on education, occupation and income since 1981 have also been linked to the cohorts.
