Longitudinal Urban Cohort Ageing Study
The LUCAS project was designed to increase knowledge in the area of functional decline and changing patterns of frailty and disability. Factors influencing these transitions and sojourn times are of particular interest both for prevention, i.e. to characterise different target groups for effective health-promotion and prevention programmes as well as health-care services planning. The major aims were:
- To describe and document certain aspects of the ageing process, e.g. the transitions from robust to frail or disabled health status;
- To find determinants of healthy ageing, based both on self-reported health information and preclinical and clinical markers obtained through medical examinations and comprehensive geriatric assessments in subsets of the cohort selected according to self-reported functional status;
- To develop a functional ability index based on self-report suitable to screen functional competence in the heterogeneous population of senior citizens in the community setting and to test its prognostic validity;
- To measure the long-term effects of a health-promotion and prevention intervention embedded in LUCAS wave 1 that showed favorable results at 1-year follow-up.

LUCAS is an ongoing longitudinal cohort study. So far, participants were assessed six times (waves 1-6), in 2000-2002 (recruitment and wave 1), 2007/2008 (wave 2), 2009/2010 (wave 3), 2011/2012 (wave 4), 2013/2014 (wave 5) and 2015/2016 (wave 6). Wave 7 is planned for 2017/2018.

Population
LUCAS population
The population is composed of independently living community-dwelling persons, aged 60 years and older, without need of nursing care (German long-term care insurance) or cognitive impairment.
The participants were recruited from 21 general practitioner (GP) practices in Hamburg.
At wave 2, to compensate for the losses since baseline, the LUCAS cohort was supplemented by the eligible patients from an additional GP practice.
Selection Criteria
- Minimum age
-
60
- Countries
-
- Germany
- Territory
- Hamburg
- Health Status
-
- At baseline, participants must not suffer from cognitive impairment or a terminal disease and not be in need of professional nursing care, or human assistance with daily activities.
- Other Criteria
- The GPs excluded those patients with (a) a need of human assistance with basic activities of daily living (ADL) or needing professional nursing care (according to the German long-term care insurance system); (b) cognitive impairment (equivalent to a Mini Mental Status score ≤24; (c) terminal disease; and/or (d) inability to understand German
- Supplementary Information about selection criteria
-
Information on health in old age generated periodically in the LUCAS cohort is largely comparable with that from representative cross-sectional studies and statistics registries.
Sources of Recruitment
- Specific Population
-
- Clinic patients
- Supplementary Information
-
General practitioners (GPs) from the metropolitan area of Hamburg were invited to participate via the newsletter of the regional GP association. Twenty-one GPs working in solo practices agreed to participate and were recruited. These GPs generated complete lists of all their patients aged 60 years and older. Eligible community-dwelling older people on the GPs' lists were invited to participate.
