Insufficiently treated diabetes mellitus can lead to severe comorbidities. National and international analyses show a continuous increase in diabetes prevalence over the last decades. Currently, an indicator-based national diabetes surveillance system is implemented at the Robert Koch Institute (RKI) to monitor and report on diabetes development on the basis of available primary and secondary data. The aim of the meeting was to go into deeper discussions and to integrate expectations and expertise of the federal states into the design of the national surveillance system. A close collaboration between the RKI and the federal states is intended.

Background: Participants of the Longitudinal Urban Cohort Ageing Study (LUCAS) were recruited from patients 60 years and older from general practitioner's offices in Hamburg. This is different from the usual methods of drawing representative samples., Objectives: The research question addressed the comparability of LUCAS results with those from cross-sectional surveys with participants randomly chosen from a population list. Therefore, the LUCAS data collected in four waves during the first 12 years were compared with data (age, gender) from the Hamburg Statistics Office (HSO), and selected characteristics (socio-demography, health, mobility) from three representative cross-sectional surveys in older Hamburg citizens., Methods: First, HSO data compiled in population pyramids for older men and women were compared with equivalent pyramids based on the LUCAS data at recruitment (2000/01) and in waves 2 to 4. Second, characteristics worded identically in the cross-sectional surveys and the simultaneous LUCAS waves were compared., Results: The LUCAS population pyramids were in good accordance at all time points with those of the general older population in Hamburg (except ages 60-64 in men in 2000). Good comparability was also found for health related characteristics from the three representative studies and simultaneous LUCAS waves (e. g. need of nursing care in 2012: LUCAS 7.1 %; Hamburg 7.4 %)., Conclusions: Information on health in old age generated periodically in the LUCAS cohort was largely comparable with that from representative cross-sectional studies and statistics registries. Older people are frequently under-represented in epidemiological studies. Therefore, the LUCAS data may provide useful information for Hamburg and similar metropolitan areas in Germany.

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).

Background: Decline in functional competence is a major determinant of older persons' needs, the development of dependency, use of care, clinical outcome and mortality. The interactions between rising life expectancy and changes in morbidity and disability warrant interdisciplinary research on functional disability, health promotion and prevention. The LUCAS (Longitudinal Urban Cohort Ageing Study) research consortium was established to study particular aspects of functional competence, its changes with ageing, to detect preclinical signs of functional decline, and to address questions on how to maintain functional competence and to prevent adverse outcome. The questions originate from problems encountered in practical health care provision in different settings, i.e. community, hospital and nursing home., Methods: The subprojects apply a longitudinal cohort follow-up study, an embedded randomised controlled intervention, cross-sectional comparative, and prospective intervention studies., Conclusion: The results will provide instruments to screen for preclinical signs of functional decline and concrete recommendations to sustain independence and prevent adverse outcomes in older age in daily practice.
