”Lifestyle factor”
• Diet and physical activity are always interrelated
• They cannot be separated
• They form the “lifestyle factor”
• Other factors, e.g. sedentary behaviour, sleep and
rest…?
Lifestyle
• Lifestyle factors have become more
important reasons for becoming ill and
drivers for the costs caused by diseases (e.g.
obesity, high blood pressure, type II DM)
• Already about 39% of 45-year-old Finns have
diabetes or prediabetes (men > women)
• Own responsibility?
Physical activity and health (WHO)
Healthy diets and regular, adequate physical activity
are major factors in the promotion and
maintenance of good health throughout the entire
life course
• Physical inactivity is estimated to cause, globally,
about 10-16% of cases each of breast cancer, colon
and rectal cancers and diabetes mellitus, and
about 22% of ischaemic heart disease
• Overall, 1.9 million deaths are attributable to
physical inactivity
Stroke, Alzheimer’s disease, Dementia
Physical activity is effective!

AHA/ASA Guideline 2001 : Physical inactivity ”less-well
documented risk factor”

high cholesterol 15 %
obesity 12 – 20%

A Society Aspect:
the Cost of Disease
•Individual
•Health care
•Other, e.g. social services
•Indirect expenses, so called productivity
costs
Cost of Health Care
• Increases more than the Gross Domestic
product (GDP)
– Primarily due to the increased costs for
improved and more complex diagnostic methods
and treatments
– Secondarily due to aging

Prevention vs. treatment
• If lifestyle for all would be the same as for
the highly educated, incidence of ”lifestyle
diseases” would be reduced by 20-40%
• Thought generally to be cost-efficient ->
start with activities that result in most
significant changes with less effort/cost
• A new way to reduce the increasing costs?

Example Calculation
• NZL Exercise on Prescription programme
implementation in FIN
– Screening €0,96/pers * 51.000
€49.000
– Intervention €76/pers * 11.780
€895.000
– Costs/year in total
€944.000
– Cost/adequately exercising
€800
– Cost / Quality adjusted life year(QALY) €1780
Savings in health care costs are 4-5x higher than the
investment

Impact on budget?
Included are not
– Indirect productivity benefits
– Private costs
Scientific evidence
• Few high-quality randomised clinical trials
on effect and cost-efficiency
• A lot of scientific knowledge of effects
• We just need to put all that in practice
• Maybe also other aspects involved, e.g.
sedentary behaviour (may provide new tools
& ways to tackle / promote)
• SO, WHAT DO WE NEED THEN?
Time for New / Combined
Approaches?
1. Methodological approach
Example: Exercise on prescription
• ”green prescription”, New Zeeland, UK
• Finnish project
• FYSS, Swedish project
Exercise on prescription
• a tool helping doctors to activate people to
become physically more active
• information occurs simultaneously when filling
up the prescription
• 5 segments:
1) exercise habits (enough or not)
2) goals for PA
3) new ”dose” for PA (what kind, how many times, how
often, what intensity)
4) extra advice
5) process follow-up, further actions
Experience…
• Hundreds of "exercise on prescription" schemes exist in general
practices in Britain.
• In a RCT the most effective intervention for promoting increased
physical activity was intensive motivational interviewing
plus a financial incentive.
• A brief intervention was largely ineffective. Short term increases
in physical activity were not maintained, regardless of the
intensity of intervention. The health benefits of physical activity
depend on sustained participation in an active lifestyle.
• These results question the effectiveness of brief
interventions to promote physical activity used by many
current UK schemes.
Harland, J. et al. BMJ 1999;319:828-832
LATER IN BMJ: "Exercise on prescription is a waste of scarce
resources”
On the other hand…
• The Green Prescription program performs
well, representing a good buy relative to
other published cost effectiveness estimates.
Policy makers should consider encouraging
general practitioners to prescribe physical
activity advice in the primary care setting, in
association with support from exercise
specialists.

physical activity counselling in general practice Aust N Z J

2. Psychological approach
The states of change
• There is some evidence that the effectiveness of
counseling may be improved by using behavioral
theories as a basis for counseling methods. One of
the most applied behavioral theories in PA
counseling is the transtheoretical model, generally
known as “the stages of change” model, which was
originally developed by Prochaska and DiClemente

smoking: toward an integrative model of change. J Cons Clin Psych
1983;51:390–5

3. Equipment approach
• Pedometers, heart-rate monitors, diaries,
handhelds, mobiles etc.
• Conclusions The results
suggest that the use of a
pedometer is associated with
significant increases in physical
activity and significant
decreases in body mass index
and blood pressure. Whether
these changes are durable over
the long term is undetermined.

My choice
• Marketing
– for physical activity
• The competitors are: TV, computer,
screentime, sofa, car
– why don’t we use the same methods
Market Segmentation, Targeting, and
Positioning
Market Segmentation
