Functioning loss is the inability to perform certain physical or mental tasks,
such as lifting, walking, balancing, reading, writing, counting, and using fingers
and hands to grasp and open. Functioning loss generally results from the onset of
diseases and conditions and occurs at a later age than disease onset. Disability is
the inability to perform an expected social role. For older people, this has generally
been defined as independent living and self-care.

For middle-aged people,
disability is defined in terms of ability to work or do housework. For children,
disability is the inability to participate in mainstream education. An important
difference between functioning loss and disability is the potential influence of the
external environment. Although in practice it may sometimes be difficult to clearly
separate the two concepts, functioning loss is defined as a functioning deficit in
an individual; disability on the other hand is an inability to perform within the
environment. Disability can be affected by conditions external to the person. For
instance, moving to a house without stairs or a home with a walk-in shower might
allow someone to...

Some people have a heart attack and die from
heart disease before they ever know they have the condition, before they have a
chance to be disabled. In addition, individuals can move in and out of some of
these health states: Disability and functioning loss may be transitory, and people
can return to full functioning and ability. Whether chronic diseases are absorbing
states from which there is no return to the healthy population depends somewhat
on the condition. We do not think of cures from heart disease, but we do speak
of cured cancer after some number of years have passed. Additionally, there is
a strong link between...

During the entire twentieth century, mortality among the old declined about 1%
per year, and the whole period has been a time of fairly regular increase in life
expectancy (43, 62, 81). There have been some years of more rapid decline in old
age mortality, such as from 1968 until the early 1980s, and years of slower decline,
such as from 1954 to 1968 (10, 43). Even the last two decades have been a mixture
of slower and more rapid periods of mortality decline for the older population (81).
Compared to the 1970s, there was substantial slowing in the rate of mortality
decline in the 1980s among...

In the 1990s the
overall rate of decline was somewhat higher than in the 1980s. Trends in annual
death rates by gender from 1981 to 1998 for three age groups of the old are shown
in Figure 2. Mortality for males in each age group shows a fairly regular decline
during the 20 years. For females in some age groups, the early 1980s were not
even a period of decline. This differential trend by gender is almost the opposite of
what occurred in the 1970s when females experienced greater decline than males.
One explanation for the different gender patterns of change is that because of their
higher likelihood...

There is mixed opinion on the likelihood of continued long-term increase in
life expectancy. Most demographers including Vaupel and Lee (44, 45, 62) are
optimistic about continued increases in life expectancy and decreases in mortality
among older persons. Olshansky (63) has been a promoter of the idea that future
increases will be minimal. The arguments for modest expectations generally rest
on the notion that it would take very substantial decreases in mortality at older
ages to achieve continued increases in life expectancy, and these would require
scientific understanding and an ability to address the basic mechanisms of aging
that are unlikely. The argument for continued optimism is that...

Although the studies differ in population coverage, sample design, method
and periodicity of measurement, use of proxies, and treatment of nonresponse and
missing data, the authors conclude that most analyses using data from the post-
1980 period show declines in the percentage with moderate disability and IADL
disability. These declines have been shown to vary by gender (18, 47) and level of
education (18); and they also differ between the young-old and the old-old (19).
Generally, there is more improvement in less-severe disability....

Trends in needing help with such activities as housework or shopping may be
due to changes in the physical abilities of the older population, but they may also be
related to the availability of help in the house, either familial or paid, the availability
of appliances, and the accessibility of transportation (1, 12). However, causes of
trends in IADL functioning have not been apportioned to reasons residing in the
person and reasons outside the person.
The trends in what is termed ADL disability have not been nearly as consistent
as those in IADL disability (31). Conflicting evidence has been provided by a
number of researchers (18, 20, 47,...

Stroke is a vascular disease for which mortality and morbidity are relatively
well-documented because most stroke victims are admitted to hospitals. Trends in
stroke mortality, incidence, and prevalence are somewhat similar to those for other
cardiovascular conditions. Stroke mortality has been decreasing since the 1960s,
but without a consistent decrease in stroke incidence. Stroke incidence has even
been reported to have been higher in the 1980s than during the 1970s, and there
was no sustained decline in incidence during the 1990s....

Among those above age 70, the average number of diseases that each person
reports has increased in recent years (17). This increase is because people have
survived a number of diseases that once would have been fatal, and they have
lived to acquire additional conditions, both potentially fatal and nonfatal, such as
arthritis. Thus, older people have more diseases, but less disability, than in the past.
Inclusion of indicators of cognitive functioning in nationally representative surveys
of the older population has allowed Freedman and colleagues (29) to estimate
change in the prevalence of cognitive impairment during a five-year period during
the mid 1990s. They estimate very significant reduction...

There are a number of well-recognized indicators of biological risk for cardiovascular
disease, diabetes, and death for which change over some period of
time can be determined from the U.S. National Health and Nutrition Examination
Surveys (NHANES). Collection of some measures began as early as the 1960s,
and some are not available until the 1980s. NHANES data show that the percentage
of the older population with high cholesterol has decreased since the 1960s,
somewhat faster for women than men (60). Examination of recent change shows
a reduction in average total cholesterol during the 1990s for the older population
(Table 2)....

In the past two decades a number of investigators have attempted to combine measures
of mortality and morbidity in order to address issues of whether Americans
are living longer, healthy lives, as well as just longer lives. In general, a life-table
approach is used to divide increases in years lived into healthy and unhealthy
years. These measures have the same useful characteristics as life-table measures
based only on mortality. They can be compared across time and place, and they
summarize a large amount of age-specific data. Because indicators of disability
are the most frequently collected measures in surveys, they have been used most
frequently to examine change over...

The general picture is that older people of today are healthier than older people
of two decades ago. There have been improvements in most dimensions of health.
People live longer and have fewer disabilities, have less functioning loss, and
report themselves to be in better health. Over time there has been some reduction
in risk from smoking and a lowering of cholesterol and average triglyceride levels.
However, weight increase has been notable during this period. Because people live
longer, a greater percentage of people have some specific common diseases, and,
on average, older people live with more diseases. The decade of the 1990s was not
one of improvement...

and gait is mostly derived from studies that measured
and reported EF as a composite score [12,18,19]. Relatively
few studies have focused on the age-related deficits
in specific components of executive function and
most of these studies were based on a traditional set of
tests of executive function, without detailing specific
components. The conclusions drawn from these studies
might, therefore, be limited by their methodologies. The
putative executive measures might not load on a single
executive construct, and might overlap with each other
[20,21]. The differential breakdown for the executive
functioning performance across patients with chronic
schizophrenia, for example, suggests that the fractionation
of central executive functioning occurs in schizophrenia
and not all EF...

Testing was performed in the gait laboratory of the City
Hospital Waid in Zurich, Switzerland. To measure
steady state walking, the central 7.32 m active sensor
area of the GAITRite® system was used as the test distance.
During the measurements, the subjects walked on
the walkway while wearing their own comfortable clothing
and low-heeled habitual shoes. Since mean values of
eight strides have been shown to be appropriately representing
gait characteristics and can be considered as
representative of normal gait [33] we ensured the capturing
of at least 25 steps per test condition. Each subject
was instructed to walk the walkway three times, in
randomised order, at I) self-selected comfortable speed,
II) a...

In community-dwelling elders, the relation
between dietary quality, social support
and living arrangements is controversial.
Some studies have found positive
relations,21,65,68,70,78-80 whereas others have
found diet quality to be unaffected by a
poor social network.81 It has been suggested
that geographical isolation has an
adverse effect on nutritional status among
the elderly.82 For instance, an urban-rural
difference in meal structure was observed
in Poland,83 with lower consumption of
certain food groups (meat, fish and eggs,
fruit and their products, and fats and oils)
in rural-dwelling seniors. It was suggested
that food distribution systems and
decreased buying power among rural
inhabitants profoundly affect food habits.
In contrast, other comparative studies of
urban and rural-dwelling seniors in the
US84,85 showed that nutrient...

More specifically, we must further examine
health beliefs, and food beliefs and
practices that have symbolic or traditional
importance to determine how knowledge,
beliefs and attitudes translate into eating
behaviour in older adults, especially at
advanced ages. More research is needed to
clarify the relative contribution of income,
ethnic background and other personal predictors
of healthy eating – self-control,
emotions, resistance to change, time constraints,
lack of knowledge – and environmental
factors governing food availability
and cost. Information is needed linking
nutritional services, health, psychological,
cognitive and social characteristics, as well
as financial constraints to procuring
healthy foods. More information is needed
on barriers, both real and perceived, that
discourage healthy eating. For instance, the
impact of therapeutic or self-imposed
restrictive...

Gaps in knowledge were detected in the
course of this review. These are summarized
in the following section, which also
suggests directions for further investigation.
Further study and regular dietary
monitoring are needed in order to know
more about food consumption habits in
seniors. These investigations must be
adapted to the reality of targeted aging
populations using precise measurements,
diverse approaches, appropriate methods
and accurate dietary assessment tools to
reflect the great heterogeneity typical of
older populations.
The research agenda should be focussed
on interactions between individual and
collective determinants of healthy eating
that are unique to the elderly in Canada.
To achieve this goal, longitudinal studies
should be conducted to examine the epidemiological
and social aspects of aging;
describe the...

Food consumption research suggests
that widowhood confers potentially negative
effects on food intake through weight
change, increased adverse health outcomes,
including depression, and diminished
“nutritional self-management”, leading to
changes in dietary behaviour and food
intakes.86,87 This is particularly evident
among men over the age of 7540,65,78,88 with
low incomes.89 Indeed, there is a strong
relation between living alone and dietary
intakes among men,80,88-90 but these findings
have not been consistent91,92 and are
even less so among women.88 Information
on the influence of living arrangements on
dietary intake in seniors appears to be
inconclusive and may depend on cultural
or other differences in the samples studied....

In an effort to modernize Medicare insurance, the Federal
government has allowed private insurers who meet strict
requirements to sell private insurance to the elderly, as a
substitute for 'traditional' Medicare insurance. There are
many forms of private insurance now being sold to the
elderly, including some managed care plan types. Managed
care plans restrict the choice of physicians and hospitals
to include a set selected by the insurance plan, over
whom the plan has more control in terms of utilization
and expenditures. Managed care plans also provide preventive
care and disease management services to their
constituents, to keep them healthier and reduce their
expenditures. Managed care plans are paid a set...

THE GROWING SIZE OF CANADA’S ELDERLY POPULATION and its use of health care services
has generated much discussion in policy circles and the popular press. With data
from the National Population Health Survey, undertaken in 1994–95, the authors
examine the health status of Canada’s elderly population using 3 sets of measures:
level of activity limitations, prevalence of chronic illnesses and self-assessment of
overall health. They also analyse the utilization of physician and institutional services.
The profile of this population the authors develop is in many respects not
much different from that of the remaining adult population, until the age of 75.
People aged 75 and over are much...

Herbert Simon’s work on bounded rationality has had little impact on health
policy discourse, despite numerous supportive findings. This is particularly sur-
prising in regard to the elderly, a group marked by a decline in higher cognitive
functions. Elders’ cognitive capacity to make decisions will be challenged even
further with the introduction of the new Medicare prescription drug benefit
program, mainly because of the many options available. At the same time, a
growing body of evidence points to the perils of having too many choices. By
combining research fromdecision science, economics, and psychology, we high-
light the potential problems with the expanding health insurance choices facing
the elderly and...

How important are these issues, and do they carry any ramifications
for the newMedicare prescription drug benefit? One of the problems, to
which Rubinstein alluded, is that elders may be facing too many options
and too much information and thus need to devise “impression manage-
ment” techniques in order to compensate for cognitive or physical loss.
To investigate this problem, which affects millions of elders throughout
the United States, our study brings together Herbert Simon’s work on
bounded rationality and research on the elderly’s cognitive ability with
more recent studies suggesting that more information and choice could
adversely affect decision makers. We provide examples from the many
temporary prescription drug...

During the past twenty-five years, numerous research studies
conducted in several fields have identified various psychosocial
factors as predictors of health and mental health status. These
include: (a) stress, (b) social support and social networks, (c)
competence, (d) socioeconomic status and (e) coping.’-&dquo; For
example, loss of a spouse (stress) may be related to depression
for one individual and high blood pressure for another person,
while a third person may experience no significant effects on
his or her well-being.
One factor that has gained prominence in the last decade as
having a...

Relatively healthy older people, particularly those in the 60 to 70 age range, are likely to need services
similar to other adult health center populations. They may face challenges similar to their younger
counterparts; language barriers, limited health literacy, or cultural factors may impact health care access.
Yet for the older-old, these familiar challenges are compounded by additional barriers to optimal care and
quality of life. The disabled of any age often need supportive services to remain as healthy as possible and
in the community. As the population ages into the 75+ or 85+ categories, there is more likelihood for...

In the field of aging, disability is measured by judging how a person performs Activities of Daily Living
(ADLs) or Instrumental Activities of Daily Living (IADLs).
ADLs include very basic activities like eating, toileting, bathing, transferring in and out of bed, and walking
(Katz, Ford, Moskowitz, Jackson and Jaffee, 1963). IADLs include additional activities needed to get along
in the world such as shopping, taking medications, using the phone, and other activities. (Lawton and
Brody, 1969.)
People may be disabled if they do not have the cognitive ability to perform functions without supervision or
assistance.
Broader definitions of disability may...

The elderly disabled often have numerous chronic conditions and functional disabilities that
require clinicians and service providers to take an ongoing cooperative management approach
with the patient and family. The goal of this approach is to live the best possible life with chronic
problems and avoid preventable deterioration of health and functional ability. In this arena, the
patient, the family, and paid or unpaid caregivers often have a significant impact on care and
quality of life, although the health center medical provider is still a critical partner in the process of
providing and authorizing necessary care....

Not every physician chooses to focus on caring for disabled elders. Physicians who work with
this population must value chronic medical and disability care and be able to work closely with
the patient, family, caregivers and other professionals to provide the best care. There are also
physiological differences in the elderly population that must be taken into account in treating and
prescribing medications. Some health centers may be lucky to have on staff some of the scarce
group of physicians who are sub-boarded in geriatric medicine. Others will have internists or
family practitioners providing care to the disabled...

Most health centers will be serving elders with disabilities in their normal adult clinics. Some may wish to
set aside special clinic times for the elderly including those with disabilities and special needs. Set-aside
times can allow for somewhat longer patient visits which are helpful in treating elders with long histories
and multiple chronic problems. Some health centers may also choose to set up additional services as part of
their approach to primary care for the elderly. These may include adult day health care, home health care,
assisted living, and nursing homes. Unfortunately we do not have an accurate count...

ADHC is a community-based health and long term care service aimed at elders or adults who are disabled
enough to be in a nursing home or at risk of nursing home placement. When coordinated with other health
center services, particularly primary care clinic services, ADHC can be critical in allowing elders to avoid
nursing home placement and helping informal caregivers to continue providing care over an extended period.
Participants live at home and are brought into the center from 3 to 5 days a week. Services may vary from
state to state but typically include an assessment and care plan with...
