Longitudinal Aging Study Amsterdam
LASA is designed to be an interdisciplinary, longitudinal study. Although basically scientific in nature, the study should provide a basis for developing and evaluating (central and local government) policy in the field of aging. The global objective of current policy in the field of aging can be formulated as enhancing the autonomy and quality of life of older persons. It is expected that by using longitudinal data, policy relevant aspects of aging can be identified and new policy aims can be developed. Moreover, assumptions from which policy measures are developed can be tested, and effects of policy changes can be assessed prospectively. LASA is primarily an observational study; the database will allow testing of various specific hypotheses. Full intervention studies will not be included in LASA.
The attached data dictionaries only contain a selection of all variables which have been translated from Dutch.

Timeline
Populations
The LASA cohort is based on a nationally representative sample of older adults aged 55–85 years (years of birth 1908–37), based in three geographic regions in The Netherlands. These three regions were selected so that an optimal representation of the older Dutch population would be achieved, with respondents from the protestant north-east, the catholic south and secular parts of The Netherlands and from both urbanized and rural areas within each of these regions. The sample was recruited from municipal registries in 1992, with an oversampling of older people and older men in particular.
