Obesity in infants, children and adults is a major problem worldwide. The prevalence
of obesity in adults is 10% to 25% in most countries of Western Europe, 20% to 25% in
some countries in the Americas, up to 40% in some countries in Eastern Europe, and
more than 50% in some countries in the Western Pacific. Obesity rates, which are
doubling every 5-10 years in many parts of the world, are placing significant additional
financial burdens on health systems to deal with the resulting problems (16). Obesity
will eventually lead to chronic disorders such as diabetes, high blood pressure, high
cholesterol levels, hardening of arteries and some forms of cancer. Obesity also leads
to acute consequences of chronic disorders including strokes and heart attacks (17;36).
Reducing caloric intake (48) and increasing physical activity (36;65) help decrease
the risk of obesity.
