In Africa countries, the WHO says the number of overweight or obese children is two times as high as it was 20 years ago. 世界卫生组织表示，发展中国家超重儿童数量急剧增加。在非洲国家，超重或肥胖儿童数量是20年前的两倍。

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, overweight or obese. 2011年，全球约430万5岁以下儿童超重。医生使用身高、体重和年龄来衡量一个人是体重不足、正常，还是超重或肥胖。
