OBJECTIVE: to describe changes in functional status of community- dwelling
Spanish elderly people, followed for 2 years, and to identify
socio-demographic and health characteristics that predict functional
change. METHOD: we have analysed data from the first two waves of the
longitudinal study, Ageing in Leganes, from a representative sample of
community-dwelling people aged 65 and over (n=1273). Functional status was
categorized according to a hierarchical scale as: completely functional,
with functional limitations, with instrumental activities of daily living
(IADL) disability, with activities of daily living (ADL) disability or
deceased. Multinomial logistic regression was used to estimate the
predictive value of selected 1993 socio-demographic and health status
variables on 1995 functional status. RESULTS: prevalence of disability
based on dependency in any of seven ADL items was 15.5%. Half of the
respondents were disabled in at least one of 10 IADLs. Some improved
functionally, others deteriorated. Men were more likely to recover function
while women were more likely to enter and to remain in the IADL state.
Socioeconomic factors were associated to baseline functional status and to
functional status change on bivariate analysis. Number of chronic diseases,
presence of cognitive problems and depressive symptoms predicted
transitions, even after controlling for baseline functional status.
CONCLUSION: although estimates of prevalence of disability among people
over 65 are higher in Spain than in other European and North American
countries, the pattern of functional changes, both in the direction of
improvement and decline, seems to be similar.
