[The Longitudinal Urban Cohort Ageing Study (LUCAS)].

BACKGROUND

The interactions between rising life expectancy, morbidity and development of disability warrant interdisciplinary research on functional disability, health promotion and prevention as well as healthcare provision for older people. Therefore, the interdisciplinary LUCAS (Longitudinal Urban Cohort Ageing Study) research consortium of university and non-university institutions was established and is coordinated by the research department of the Albertinen-Haus at the University of Hamburg. The aim is to study particular aspects of functional competence, the changes with ageing, to detect pre-clinical signs of functional decline and to address questions on how to maintain functional competence and to prevent adverse outcomes. The research questions have their origin in problems of practical healthcare provision in the different settings of communities, hospitals and nursing homes. The articles of LUCAS subprojects report selected results from the first project phase (2007-2010) which was funded by the German Federal Ministry of Education and Research (BMBF) (Research program"Health in the elderly").).

METHODS

The LUCAS subprojects 1-7 applied a true cohort study design with embedded randomized controlled intervention studies and cross-sectional studies for comparative purposes and to prepare intervention studies to be performed in the second project phase.

CONCLUSIONS

Results from the first project phase provided new instruments to screen and to assess functional competence in older people (population-based screening). In the second project phase these will be evaluated according to practicability and usefulness. Furthermore, parts of the results will be used by the health reporting system in Hamburg and for intervention studies performed by LUCAS subprojects during the second project phase (LUCAS II).
