title: [Longitudinal study in the elderly in The Netherlands: an inventory focused on policy relevance].
abstract: With the purpose of gathering policy relevant information on changes in functioning of older persons, in 1989/1990 an inventory was made of longitudinal research in the Netherlands in which data on the older population are collected. The inventory resulted in a list of over thirty studies in a wide range of disciplines. The stage of these studies was updated in mid-1992. In this paper, the studies are categorized according to ten themes relevant to the policy on aging. The themes are based on the Lalonde model of prevention and on the WHO classification of impairments-disabilities-handicaps, which were extended to the full life sphere of older persons. Each study is briefly described. For each theme is indicated what contribution the existing research can make to the policy relevant information sought. It is concluded that thus far no comprehensive, multidisciplinary study was available which can provide integrated information on changes in functioning of older adults.
