对89名单纯性肥胖儿童做了手腕部骨龄发育的病例对照研究。结果表明:(1)肥胖儿童骨龄提前(平均男孩提前1.02岁,女孩提前0.74岁,P<0.001)。(2)肥胖儿童骨骼发育速度比正常儿童快(平均男孩快0.117y/a,女孩快0.09y/a,P<0.001)。(3)男孩肥胖度与骨龄增值之间以及骨龄与身高之间均存在有同向变化关系。
A case-control study of the skeletal age development of wrist in 89 simple obese children. The results showed that: (1) The skeletal age of obese children was advanced (average age of boys was 1.02 years in advance and that of girls 0.74 years in advance, P <0.001). (2) Skeletal development rate of obese children was faster than that of normal children (average fast boy 0.117y / a, fast girl 0.09y / a, P <0.001). (3) The relationship between the obesity degree and the increment of skeletal age, as well as between the bone age and the height of boys have the same direction change.
