Many people believe that a child "baby fat" is the performance of health, to a certain age will be "pumped" thinner. However, on the 5th U.S. scientists published a research report said that each child is not able to "pump", childhood overweight grow up overweight or obese have a greater risk.
According to U.S. media reports, the United States, an honorary professor at the University of California feiliponat reported that their study found that more than 2-year-old pre-school children are overweight, 12-year-old overweight face more than the risk of childhood overweight is not large 5-fold .

The study focused on 1042 1991, the United States-born children, in their 2-year-old to 12-year-old, the scientists measured 7 times their height and weight.

Usually the international body mass index BMI (body weight divided by height squared) to measure whether people are overweight. General BMI value of 18.5 to 25 for a healthy weight, overweight for more than 25.

The report said that before the 3-year-old BMI than 50% to 84% of the same age, same-sex child who, at 40 percent overweight at the age of 12. In contrast, the primary stage of the BMI than 50% of the same sex were the same age, small children, no one at the age of 12 are overweight.

科普:“婴儿肥”易带来成年超重

许多人认为小孩子“婴儿肥”是健康的表现,到了一定年纪就会“抽条”变瘦。但美国科学家5日发表的研究报告说,不是每名幼儿都能“抽条”,幼时超重者长大后超重或患肥胖症的风险也更大。
  据美国媒体报道,美国加州大学名誉教授菲利普·纳德发表报告说,他们的一项研究发现,2岁以上学龄前儿童超重者,12岁时面临超重的风险比幼年时不超重者大5倍。

  本次研究的对象是1042名1991年出生的美国儿童,在他们2岁到12岁期间,科学家7次测量他们的身高和体重。

  国际上通常用身体质量指数BMI(体重除以身高的平方)来衡量人是否超重。一般BMI数值在18.5到25之间为健康体重,超过25的为超重。

  报告说,3岁之前BMI比50%到84%同龄同性者大的儿童中,有40%在12岁时超重。相比之下,小学阶段BMI比50%同龄同性者小的儿童中,没人在12岁时超重。

  资助这项研究的美国国家儿童健康发育研究所的所长杜安·亚历山大说:“这些发现强调,人在童年时就有必要保持健康体重。与通常观念相反,超重或肥胖儿童通常不会随着年龄变大而减去额外的体重。”
