重庆地区1 124名汉族青少年的骨龄调查

Investigation of skeletal age of 1 124 Han adolescents in Chongqing area

摘要:

目的：通过对重庆地区1 124名汉族青少年的骨龄调查，分析其与生长发育的关系。方法：采用分层整群抽样调查的方法，随机选择重庆地区7～19岁健康汉族青少年1 124人，测量身体机能与身体形态指标，按《中国人手腕骨发育标准-中华05》进行手腕部骨龄评价。结果：骨龄与生活年龄呈正相关关系（男性r=0.924，女性r=0.880，合计r=0.902，P=0.000），骨龄与生活年龄呈线性关系（男性y=-0.004＋1.039x，P=0.000，女性y=-0.838+1.112x，P=0.000，合计y=-0.414+1.076x，P=0.000）。男性与女性比较其生活年龄、骨龄、身高、体质指数（body mass index，BMI）、舒张压、血红蛋白和体脂肪差异有统计学意义（P<0.05），而体质量、收缩压、脉搏和血糖差异无统计学意义（P >0.05），骨龄与生活年龄、体脂肪、身高、性别和BMI有关（P<0.05）。结论：重庆地区不同性别汉族青少年骨龄、身高存在差异，骨龄与生活年龄呈线性关系，骨龄随着生活年龄的增长而增长。

Abstract:

Objective：To investigate the skeletal age of 1 124 Han adolescents in Chongqing area and to analyze the relationship be－tween skeletal age and growth and development. Methods：Total of 1 124 healthy Han adolescents aged 7-19 years old living in Chongqing area were randomly selected by the stratified-cluster sampling method. Indexes of their body shape and function were measured. Skeletal age at wrist was scored according to standards of skeletal maturity of hand and wrist for Chinese-China 05. Results：There was a high positively correlation between skeletal age and chronological age（male：r=0.924，y=-0.004＋1.039x，P=0.000；female：r=0.880，y=-0.838+1.112x，P=0.000；totally：r=0.902，y=-0.414+1.076x，P=0.000）. There were differences in chronological age，skeletal age，height，body mass index（BMI），diastolic blood pressure，hemoglobin and body fat between male and female（P<0.05）. There was no difference in weight，systolic blood pressure，pulse and blood glucose between male and female（P >0.05）. There were relationships between skeletal age and body fat，height，gender and BMI（P<0.05）. Conclusions：There are differences in skeletal age and height between male and female Han adolescents with different ages in Chongqing area. There is a linear relationship between skeletal age and chronological age. Skeletal age increases with the increase of chronological age.
