Physical inactivity is becoming a world-wide epidemic – and the consequences can be both costly and deadly. This was outlined by Dr. Jonathan Myers who, citing a range of studies and recent research results, was able to show hard-hitting data related to the correlation between fitness (or lack thereof) and poor health. Myers argues fitness may well be a better marker than traditional risk factors for CVD and all-cause mortality. Amongst the eye-opening findings presented to the audience was that, for the first time, global deaths-per-year due to physical inactivity are higher than for smoking.

activity – WHO, CDC, AHA, ACSM, US
Surgeon General’s Report, IOM, DHSSPS,
European Working Group*
“All individuals should attempt to accumulate 30
minutes of moderate activity on most, if not all,
days of the week”
“Additional health benefits can be gained through
greater amounts of physical activity…”
30 minutes daily activity ≈20 to 40% reductions in
cardiovascular and all-cause morbidity/mortality

ØOverall healthcare costs ≈40% lower among “sufficiently active” vs.
insufficiently active subjects with metabolic syndrome.1
ØOverall 11.1% of health care expenditures attributed to inadequate physical
activity in the US.2
ØWorkplace wellness program saved PepsiCo $1,632 per employee per year,
driven largely by 29% reduction in hospital admissions3
ØFor every euro invested in physical activity there is a €3.21 savings on
medical costs.4
ØIn Australia, for every 1% increase in adult activity levels, there is an
estimated combined savings of nearly €4.26 million in potential treatment
costs for MI, stroke, diabetes, colon cancer, breast cancer and depressive
disorders.5

Care System
n Assuming $1 saved per kcal expended/week
n Meeting the minimal recommendations for activity
(30 min/day ≈ 1000 kcal/week) amounts to $50,000
in cost savings/year
n 30% of patients seen in Cardiology report no
physical activity; another third doesn’t meet the
minimal recommendations
n 15,000 patients seen/year in the Cardiology clinics
n If these sedentary patients walked 30 min/day, $50
million would be saved

35. Summary
n Higher fitness is associated with significantly lower
overall health care costs
n Age-adjusted costs in the least-fit quartile are 30-
50% higher than subjects in the fittest quartile
n Annual cost reduction per patient of $1,592 per MET
achieved
n Cost savings with higher fitness are more evident in
overweight and obese subjects
n Fitness is a strong predictor of health care costs
n There is a growing body of objective, economic-based
evidence for employers, health care professionals,
and professional organizations to promote physical
activity
