Childhood obesity

Childhood obesity is already common, especially in westernized countries. In 2004, according to IOTF (now known as World Obesity Clinical Care) criteria, it was estimated that ~10% of children worldwide aged 5–17 years were overweight and that 2–3% were obese (Lobstein et al., 2004). Prevalence rates vary considerably between different regions and countries, from <5% in Africa and parts of Asia to >20% in Europe and >30% in the Americas and some countries in the Middle East.   Becoming obese earlier in life clearly amplifies certain health risks, particularly for type 2 diabetes.
