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。
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+l.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.
