Aim: to obtain population data on health status and disability of elde
rly people which may help in planning and maintaining services and be
used as comparators for research. Method: random samples of people age
d 70 and over were interviewed in their own homes in West Glamorgan, D
udley and North Staffordshire. The interviews included standardized as
sessments of health status (SF-36), disability (Barthel index) and cog
nitive function (Abbreviated Mental Test). Results: 1608 interviews we
re completed. Response rates varied between 66 and 84%. Age and sex ad
justed scores for five of the eight parameters of the SF-36 and the Ba
rthel score differed significantly between districts. Conclusions: loc
al studies are required to provide appropriate normative data for each
area. In the absence of such studies, the data in this paper are the
best currently available.
