Childhood obesity is increasing at an alarming rate throughout the world. The World Health Organization calls it one of the most serious public health problems of the 21st century.
Overweight children are likely to become obese adults, who have a higher probability of developing diabetes and cardiovascular diseases at a younger age. These diseases can cause disabilities and premature death.
Globally, the number of overweight and obese children under the age of five was estimated to be more than 42 million in 2010.
While most people think being fat is a problem only in rich countries, nearly 35 million of these children were living in developing countries. The childhood obesity problem is rising rapidly in low- and middle-income countries, especially in urban areas.
The rate of children who are overweight and obese worldwide increased from 4.2% in 1990 to 6.7% in 2010, according to the American Journal of Clinical Nutrition.
