[Longitudinal data related to health. A survey of health related panel studies in Germany]

Individual longitudinal data are indispensable for studying the differential incidence of diseases and of possible chronic conditions, health care interventions and outcomes in the course of time, the effects of changing population structure on morbidity, the demand and use of health services, as well as the efficacy and efficiency of health care guidelines. Here, we present an up to date survey of panel studies in Germany, in so far as these are either still active or were completed only recently, and in so far as they are accessible via public use files or equivalent solutions for the scientific community. There are some health related items on existing general purpose national panel studies, but no health related representative national panel study. In addition to the well known unique potential of panel data, we demonstrate, for special populations (e. g. foreigners and people living in institutionalised settings), as well as for special items (salutogenetic potentials and preventive resources), the particular need for health related panel data in the German context.
