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 4
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 5
Lay views
There are a few investigations into older people’s views of what is
successful ageing.
Prof Y Barak, MD, MHA 6
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 7
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 8
Additional lay definitions
•Accomplishments•Enjoyment of diet•Financial security•Neighbourhood•Physical appearance•Productivity and contribution to life•Sense of humour•Sense of purpose•Spirituality
Prof Y Barak, MD, MHA 9
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.

Successful Aging
Vaillant & Mukamal, Am J Psychiatry, June 2001.
Prof Y Barak, MD, MHA 11
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 12
Conceptualizing Aging
Aging can be seen from 3 dimensions Decline Change Development
Prof Y Barak, MD, MHA 13
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 14
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 15
Development
At 70 we are more Patient Accepting of affect in
ourselves Likely to tolerate
paradox
Prof Y Barak, MD, MHA 16
The Berlin Aging StudyBaltes & Mayer, 1999.
The MacArthur Study of AgingRowe & 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 17
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 18
The Study of Adult DevelopmentBackground
The SAD was initiated in Harvard
Two socially diverse cohorts of adolescents (college vs. core-city) were followed until they became great-grandfathers
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 19
The Study of Adult DevelopmentDefinitions & 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 20
The Study of Adult Development
Outcome Domains Physician assessed
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)
Objective mental health (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 21
The Study of Adult DevelopmentSubjects
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 22
The Study of Adult Development
Independent Predictor Variables Smoking (pack years) Alcohol
abuse/dependence (DSM-III)
BMI (at age 50) Years of education
(core-city only) Regular exercise (500
kCal/week) Stable marriage
Maturity of defenses (at age 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)

The Study of Adult Development
Results (3) Correlation of Predictor variables (before age 50) with 5 aging Outcomes
Controllable variables: Smoking Alcohol Exercise BMI Stable marriage Maturity of defenses
Uncontrollable variables: Depression Parental social class Warmth of childhood Ancestral longevity Childhood temperament Objective disability at age 50
Prof Y Barak, MD, MHA 26
The Study of Adult Development
Results (4) Correlation of Predictor variables (before age 50) with 5 aging Outcomes
For both college and core-city 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 27
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 self-care 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 28
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 29
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 old-age may lie not so much in our stars and genes as in ourselves
Joseph S. Alpert, MD
“12 Guides to Health, Happiness, and Longevity”
The American Journal of Medicine, Vol 121, No 7, July 2008
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.
