The World  Health Organization(WHO)  says there has been a sharp increase in the number of children in developing countries who weigh too much.  In African countries, the WHO says the number of overweight or obese children is two times as  high  as it was 20 years ago.

Around the world, about 43 million children under the age of five were overweight in 2011. Doctors use height, weight and age to measure whether a person is underweight, normal, or obese.                              

Overweight children are more likely to become overweight or obese adults.  The condition can lead to serious health problems like diabetes, heart disease and stroke.

Francesco Branca , director of the WHO Department of Nutrition for Health and Development, says people are eating manufactured or processed food more often, which often has a high sugar. fat and salt content.  Another reason of gaining weight is the city lifestyle.  They travel in cars or other vehicles more than on foot, and have less physical activities in general.

Mr Branca says reducing the number of overweight children will not be easy.  He says the goal is difficult to meet even in wealthy countries.

The WHO has some basic solutions for individuals（个人） : to lower your in-take of fat ,sugar, salt and processed food, eat more fruit and vegetables, and increase physical activity .These actions are especially important for children and governments should concern providing vitamin for children .

Reducing the number of overweight children will not be easy.  The goal is difficult to meet even in wealthy countries. Educational campaigns about problems linked to obesity would also help. Food manufactures must balance quality and taste with the dangers of sugar, fat and salt.

The current goal of the WHO's World Health Assembly is to prevent an increase in the percentage of overweight children during the next twelve years.
