# ACTIVE LIFE EXPECTANCY IN THE OLDER POPULATION

## Abstract

The general aim of this research is to use the multistate approach to
active life expectancy to provide a fuller portrayal of the interaction
of health and mortality change among the older members of the American
population.  The impetus for this study comes from a desire to clarify
how change over time and differences at a point in time in mortality and
morbidity conditions can affect the health status of a population.  Given
the recent remarkable changes in old-age mortality int eh United States,
our analysis will demonstrate the effect of such changes on active life.
Moreover, given the current stratification of morbidity rates across
sociodemographic groups, our analysis attends to major cleavages in
active life expectancy among the oldest members of the American
population.  Our strategy to examine these issues rests on the following
specific aims:

1) the estimation of levels of active and inactive life expectancy during
the mid 1980's.  In this phase of the study, we question the utility of
previously employed definitions of active and inactive life and propose
a division of life expectancy into states based on ability to provide a
set of basic needs of life.  These definitions divide life when
functioning is less than complete into a set of policy=relevant health
states.

2) the use of simulation techniques to determine the likely effects of
known changes in past and possible future changes in mortality and
morbidity transition schedules as well as population composition changes
on estimated active life expectancy and the prevalence of disability in
surviving populations.

3) the use of multivariate hazard models to probe the social, demographic
and medical correlates of changes in health status in old age; and

4) to derive active life tables from the multivariate hazard models to
achieve a substantive interpretation of he implications of the combined
set of hazard-model estimates from older persons' health events.  This
will result in life tables for more detailed subgroups of the population
than has previously been possible.  Further, this approach will allow the
identification of how sociodemographic characteristics shape the
potentially complex process by which individuals experience declines in
health.

In recent years people with cystic fibrosis (CF) are living longer, more
productive lives.  Still, CF is a chronic ad lethal disease.  While the
psychosocial problems and interventions for children and adolescents with
CF and their families have been extensively researched an discussed,
there has been far less attention to the needs of adults with CF, a
growing clinical population.  Most have outlived their life expectancies,
and have more or less successfully negotiated developmental challenges
around forming mature relationships, sexuality, independence,
educational/career goals, and satisfactions with one's experiences and
achievements.  With age, the disease process causes physical
deterioration.  Issues of mortal...
