GEDA – German Health Update

Project manager: Dr. Cornelia Lange (Unit 24)

The Robert Koch Institute regularly conducts health interview surveys as a part of its nationwide health monitoring. These studies complement other surveys such as DEGS or KiGGS. They enable the government to respond quickly and flexibly in the field of health policy. Through the continuous monitoring of the health of the population, changes over time can be observed and effects of health policy measures detected.

The Robert Koch Institute's current health interview survey began in November 2014 (GEDA 2014/2015-EHIS). About 20,000 people living in 255 selected communities aged 15 and over will be interviewed. The field phase will be finished by July 2015. For the first time, the questionnaire of the European Health Interview Survey (EHIS) is integrated in the survey.

The survey focuses on the following subjects:

  • subjective health
  • prevalence of diseases
  • accidents
  • mental health
  • functional limitations
  • health-related behaviour, e.g. utilization of vaccinations, diet, physical activities
  • risk factors, e.g. alcohol consumption, smoking
  • socio-demographic characteristics such as education, occupational status, migration background.
