The Research Data Center of the Robert Koch Institute (FDZ RKI) provides the data of population-representative health surveys. The main objective of health surveys is to obtain information that is as representative as possible of the health status and health behaviour of the resident population in Germany. The methodology, i.e. the sample design, the principles of operationalization and measurement as well as data collection techniques, is largely based on the tried-and-tested methods of empirical social research. In the context of Health Interview Surveys (HIS), established survey techniques such as filling out questionnaires, telephone interviews, computer-assisted personal interviews or online surveys via the Internet are applied. The main difference compared to purely socio-scientific surveys is the additional examinations, tests and medical-biochemical measurements which, in addition to the survey results, provide a clear added value. This part is internationally known as Health Examination Survey (HES).
Table 1 lists the health surveys conducted by the RKI, whose data are also available for external scientific analysis.
The data are available to interested scientists as factually anonymous data for scientific secondary analysis upon request.
Data access is provided by providing a Scientific Use File as a download link. Data that are not part of the Scientific Use File can be applied for within the scope of an extended data use. A workstation for guest researchers at the Robert Koch Institute is available for analysis with data sensitive to data protection law.
