27.	Um ein globaleres Maß für den Erkrankungszustand der Untersuchungsteilnehmerinnen und -teilnehmer zu gewinnen, wurden einzelne Diagnosegruppen zu komplexeren Krankeitsbildern aggregiert. Zu jeder dieser aggregierten Diagnosen existiert je eine Variable für den medizinischen Schweregrad, das Ausmaß der vitalen Bedrohung und den subjektiven Schweregrad der Erkrankung. Eine ausführliche Begründung und Beschreibung dieses Vorgehens findet sich im Kapitel 6 des Begleitbuches zur Berliner Altersstudie. Genaue Informationen zur Vorgehensweise bei der Aggregierung sind im Büro der zentralen Projektkoordination auf Anfrage erhältlich.	To gain a more global view on a participants' status of health, selected diagnoses were aggregated to establish a more complex syndrome. For each of these aggregated diagnoses one variable exists for each of the following: degree of medical severeness, degree of vital threat and degree of subjective severeness. A detailed description and justification of this procedure can be found in chapter 5 of the BASE-handbook. Detailed information on the process of aggregation itself is available in the office of the central project-coordination upon request.
