SUMMARY OF KEY FACTS ON OBESITY AND THE ECONOMICS OF PREVENTION

At least one in two people is now overweight or obese in over half of OECD countries. Rates
are projected to increase further and in some countries two out of three people will be obese
within ten years.

The latest data show a slowdown of the epidemic in several countries, with virtually stable
rates in Korea, Switzerland, Italy, Hungary and England over the past ten years, and mild
increases in France and Spain. However, larger increases were recorded in Ireland, Canada
and United States.

An obese person incurs 25% higher health expenditures than a person of normal weight in
any given year. Obesity is responsible for 1-3% of total health expenditures in most OECD
countries (5-10% in the United States). Obese people earn up to 18% less than non-obese
people.

Poorly educated women are two to three times more likely to be overweight than those with
high levels of education, but almost no disparities are found for men. OECD countries have
made no progress in tackling these disparities.

comprehensive prevention strategy would avoid, every year, 155 000 deaths from chronic
diseases in Japan, 75 000 in Italy, 70 000 in England, 55 000 in Mexico and 40 000 in
Canada.

The annual cost of such strategy would be USD 12 per capita in Mexico, USD 19 in Japan
and England, USD 22 in Italy and USD 32 in Canada. The cost per life year gained through
prevention is less than USD 20 000 in these five countries.
