The Controversy
A forward looking policy for older age
would be a programme to promote
successful ageing from middle age
onwards, rather than simply aiming to
support elderly people with chronic
conditions.
But what is successful ageing? And who
should define it?
Prof Y Barak, MD, MHA

Method
Included in analysis
were 170 papers
presenting reviews or
overviews of the topic,
data from cross
sectional and
longitudinal surveys,
and qualitative studies.
Also included were lay
definitions elicited from
our own recent survey
of successful ageing.
Prof Y Barak, MD, MHA
4
Lay views
There are a few investigations into older
people’s views of what is successful
ageing.
Prof Y Barak, MD, MHA
5
UK Survey
A national, random population survey of
perceptions of successful ageing among 854
people aged 50 or more, living at home in
Britain.
Part of an Office for National Statistics
omnibus survey.
Of these people, 75% (631) rated themselves
as ageing successfully “Very well” or “Well”
Prof Y Barak, MD, MHA

Lay Definitions
The most commonly mentioned
definition of successful ageing, in
response to open ended questioning,
was having good health and functioning.
These were rarely mentioned in
isolation, and most people mentioned
more than one definition
Prof Y Barak, MD, MHA

Additional lay definitions
Accomplishments
Enjoyment of diet
Financial security
Neighbourhood
Physical appearance
Productivity and contribution to life
Sense of humour
Sense of purpose
Spirituality

Policy implications:
lay opinions
With greater recognition that older people are
not a homogeneous group, health
professionals need more balanced,
interdisciplinary perspectives of older age.
Clinicians need to be aware of their patients’
values and expectations of ageing in order to
enhance mutual understanding of their health
goals and priorities, and to consider
interventions that will optimize their chances
of “ageing successfully” in their terms.

Epidemiology
In 1990 there were 4
million Americans
age 85 and older
In 2040 there will be
X10 that many
The increase is
mainly due to more
people living to age
65
Prof Y Barak, MD, MHA

Conceptualizing Aging
Aging can be seen from 3 dimensions
Decline
Change
Development
Prof Y Barak, MD, MHA
12
Decline
By age 70 we
identify only 50% of
the smells
Night vision
declines…by age 80
few can drive at
night
By age 90 50% can
not use public
transportation
Prof Y Barak, MD, MHA
13
Change
Hair, waistline,
skin…change
Making love shifts from
3/week to 2/month
Our ability to love and
be loved does not
diminish
Our capacity for joy is
undiminished
Prof Y Barak, MD, MHA
14
Development
At 70 we are more
Patient
Accepting of affect in
ourselves
Likely to tolerate
paradox
Prof Y Barak, MD, MHA
15
The Berlin Aging Study
Baltes & Mayer, 1999.
The MacArthur Study of Aging
Rowe & Kahn, 1999.
The 2 most important
predictors of successful
aging were:
High level of education
Extended family network
“Our greater longevity is
resulting in LESS, not
more, years of
disability.”
Prof Y Barak, MD, MHA
16
A Prospective Study of Successful Aging:
The Study of Adult Development
Vaillant & Mukamal, 2001
Until now we have NOT known how to predict
successful aging
All large-scale prospective studies were
flowed by “selective mortality” : by beginning
in late life these studies failed to include
those who died before age 60 or 70
The Study of Adult Development (SAD)
provides a way around some of these
difficulties
Prof Y Barak, MD, MHA
17
The Study of Adult Development
Background
The SAD was initiated in
Harvard
Two socially diverse cohorts
of adolescents (college vs.
core-city) were followed until
they became greatgrandfathers
Birth cohort was limited to
the period 1918-1932
Gender (male), Nationality
(USA) and Skin Color (white)
were held constant
Prof Y Barak, MD, MHA
18
The Study of Adult Development
Definitions & Domains
Six domains of function were
chosen to classify old-age
along a continuum from
”happy-well” to “sad-sick”
Individuals who did well in all
6 areas until age 80 were
classified as “happy-well”
Those who were both
psycho-socially unhappy and
physically disabled were
“sad-sick”
Those who fell in between
were classified as
intermediate
Prof Y Barak, MD, MHA
19
The Study of Adult Development
Outcome Domains
Physician assessed
Objective mental health
objective physical health and
absence of irreversible
physical disability
Subjective physical health
(instrumental tasks of daily
living)
Length of active life (No. of
years before age 80 without
objective/subjective physical
disability)
(evidence of
competence in 4
domains: work,
relationship, play and
NO psychiatric
care/medication)
Subjective life
satisfaction
Social support
(objective evidence of
friends)
Prof Y Barak, MD, MHA

The Study of Adult Development
Subjects
College cohort:
268 subjects
Harvard sophomores
Selected for physical and
mental health
Core-city cohort:
456 subjects
Nondelinquent
Mean IQ 95
Mean education 10 years
Prof Y Barak, MD, MHA

The Study of Adult Development
Independent Predictor Variables
Smoking (pack years)
Maturity of defenses (at age
Alcohol
abuse/dependence
(DSM-III)
BMI (at age 50)
Years of education
(core-city only)
Regular exercise (500
kCal/week)
Stable marriage
47; DSM-IV Defensive
Functioning Scale)
Depression (before age 50)
Parental social class
Warmth of childhood
Ancestral longevity (mean
mother’s and father’s age at
death)
Stable childhood
temperament (parental
report)
Objective disability (at age
50)

Correlation of Predictor variables (before age 50) with 5 aging Outcomes
Controllable variables:
Smoking
Alcohol
Exercise

Stable marriage
Maturity of defenses
Uncontrollable variables:

The Study of Adult Development
Results (4)
Correlation of Predictor variables (before age 50) with 5 aging Outcomes
For both college and corecity men absence of
alcohol and cigarette
abuse (less than 30
pack-years) before age
50 were the most
IMPORTANT protective
factors for successful
aging
Prof Y Barak, MD, MHA
26
The Study of Adult Development
Results (5)
Correlation of Predictor variables (before age 50) with 5 aging Outcomes
Exercise and education are
indirect measures of selfcare and perseverance
Both appeared to be
important predictors of
multiple domains of
successful aging
Preseverance (tested by the
5 mts treadmill test) at age
19 predicts 61% happy-well
vs. 13% of the sad-sick
(NOT explained by physical
fitness) p=0.005
Prof Y Barak, MD, MHA
27
The Study of Adult Development
Results (6)
Multivariate model
Each of the 6 factors over which an individual has some control
predicted successful aging when other factors were statistically
controlled
The importance of alcohol abuse (core-city) and smoking
(college) were masked by colinearity
Uncontrollable factors
NOT significant:
Parental social class
Unhappy childhood
Ancestral longevity
Significant:
Depressive disorder before 50
Prof Y Barak, MD, MHA

The Study of Adult Development
MESSAGE
The 7 protective factors that
distinguish happy-well from
sad-sick are under some
personal control
We have considerable
control over our weight,
exercise, education, smoking
& alcohol abuse
Hard work/therapy can
modify our coping styles &
relationship with spouse.

The Future
Successful oldage may lie
not so much
in our stars
and genes as
in ourselves

Prof Y Barak, MD, MHA
31
Guide #1:
Try to be born into a family with a
history of longevity.
There is no replacement for good genes.
This is the single factor that one cannot
influence with a change in
lifestyle or attitude.
Prof Y Barak, MD, MHA
32
Guide #2:
Never smoke!
If you are unlucky enough to
be a current smoker, quit the moment you
finish hearing this
lecture.
Prof Y Barak, MD, MHA
33
Guide #6:
Don’t get fat.
It is okay to be a few kilograms
(and only a few) over your ideal weight.
If you are 5 kilograms or more over your
ideal body weight, start
a program of dieting and exercise.
Consult
Prof Y Barak, MD, MHA
34
Guide #9:
Cultivate family and friends.
Enjoy conversation,
dining, and recreation with people whom
you like (for example, your spouse).
Spend as little time as possible with
folks you don’t like or who make you
uncomfortable.
Prof Y Barak, MD, MHA
35
Guide #11:
Be informed,
but try not to be overwhelmed
by current events as portrayed by the
popular media.
