Description.Abstract
Context
: The
risk
of
developing
dementia
increases
with
age
. With the
general
public
living
longer
,
more
strategies
for
promoting
healthy
aging
and
cognitive
function
will be
critical
.
Many
findings
have
shown
that
increased
physical
activity
and the
social
environment
play
important
roles
in
dementia
prevention
.
However
, the
actual
elements
of a
neighborhood
environment--both
physical
activity
and
social
environment--that
promote
healthy
brain
aging
are
uncertain
.
We
hypothesized
that
individuals
with
greater
neighborhood
accessibility
will have
better
cognitive
function
through
more
physical
activity
,
walking
, and
social
stimulation
.
Objective
: To
determine
how
neighborhood
accessibility
is
associated
with
cognitive
function
and
dementia
among
Portland
area
older
adults
using
perceived
and
objective
measures
in
2004
.
Study
Population
:
133
older
adults
,
59
to
95
years
old
,
selected
from the
three
prospective
cohorts
within
the
Layton
Aging
&
Alzheimer’s
Research
Center
at
OHSU
, the
Oregon
Brain
Aging
Study
(OBAS)
, the
Dementia
Prevention
Study
(DPS)
, and the
African
American
Dementia
and
Aging
Project
(AADAPt)
.
Methods
:
Neighborhood
accessibility
was
determined
subjectively
through
a
questionnaire
and
objectively
through
the
Regional
Land
Information
System
of the
Portland
government
. These
scores
were
compared
using
linear
and
logistic
regression
models
to
three
cognitive
tests
(Animal
Fluency
,
Logical
Memory
, and
Clinical
Dementia
Rating)
to
determine
the
association
between
neighborhood
accessibility
and
cognitive
function
while
controlling
for
other
risk
factors
.
Conclusion
:
No
significant
associations
between
neighborhood
accessibility
and
increased
cognitive
function
were
found
.
Overall
,
individuals
with
higher
neighborhood
accessibility
scored
no
better
or
worse
on
cognitive
tests
than
individuals
with
low
neighborhood
accessibility
.
