7～12岁肥胖儿童骨骼发育的观察

Investigation on Skeletal Development of Obese Children Aged 7—12

通过1:1配对比较,102名肥胖组儿童(男73例,女29例)的手腕骨发育水平优于对照组儿童,男女肥胖组骨龄均值皆大于对照组,其中男性大0.6岁、女性大0.7岁。肥胖组儿童的拇指内侧种籽骨萌出率高于对照组,且男性差别显著。骨观察标志也多表现为肥胖儿童发育领先。

The skeletal development of 102 obese children (73 boys and 29 girls) aged from 7 to 12 was investigated by 1 to 1 matched case-Control study. The following results were obtained: The average skeletal ages of boys and girls in case groups were 0.6 and 0.7 years greater than those of the controls respectively. There was a higher percentage of ossification of the sesamoid in male cases compared with the controls. The other signs of bone in case group also developed earlier than those in control group. Because the conrtols were selected with restricting chronological age and height, the difference of skeletal development observed in this study expressed the real effect of obesity.
