有很多长得较胖的女孩子,虽然还只是小学生,却看起来已经发育得挺成熟了。另一方面,则有很多胖男孩,虽然已经是中学生,但仍然未脱稚气。美国小儿科学会的学术刊物近日刊登了关于上述内容的调查结果。经调查1500名8至14岁的少男少女后发现,女孩越胖性成熟越早,相反男孩则越胖性成熟越晚。该调查是由美国伊利诺伊大学人类营养学系的研究人员实施的。研究人员对调查对象进行了体检,将性成熟水平分为5个阶段进行评价,然后分析在各个年龄段,性成熟和肥胖度间的相关关系。
There are a lot of fatter girls, though still only primary school children, but they seem to have grown quite mature. On the other hand, there are many fat boys who, though they are secondary school students, are still not childish. The academic journal of the American Academy of Pediatrics recently published the findings of the above. The survey of 1,500 boys and girls aged 8 to 14 found that the older the girl, the older the more fat, on the contrary, the more fat the boys mature later. The survey was conducted by researchers at the Department of Human Nutrition at the University of Illinois, USA. The researchers conducted a physical examination of the subjects, dividing the level of sexual maturity into five stages for evaluation, and then analyzing the correlation between sexual maturity and obesity in all age groups.
