儿童身高生长追踪研究

以北京市106名儿童为样本 ,为研究各年龄生长速度的集中趋势、变异状况以及与生长速度有关的参数 ,追踪观察这些儿童自6、7岁至 18岁时共12年的身高变化 ,并做有关参数分析。报告了各年龄组身高生长速度的均值及标准差 ,该组儿童身高生长突增开始年龄 (男10.73±1 .12岁 ,女 9.00± 1.18岁 )及速度 (男4.51± 0.65cm/年 ,女 4.95± 0.79cm/年 ) ;身高生长高峰发生年龄 (男 1 3.0 7±1.08岁 ,女11.32± 1.32岁 )及速度高峰值 (男10 .01± 1.59cm/年 ,女8.13± 1.03cm/年 ) ;以及生长突增结束年龄 (男16.18± 1.02岁 ,女 13.96± 1.09岁 )。分析了最终身高与生长突增有关指标的相关关系。

LONGITUDINAL STUDY ON CHILD HEIGHT GROWTH

Longigudinal research on height growth was carried out in Beijing , China. There were 109 boys and girls in the group. The height growth had been followed from their age of 6— 7 through 18 ( for 12 years). The central and dispersion trend of height velocity by age was reported; indices on growth velocity were listed: age at take-off ( TOA) ( boy s 10. 73± 1. 12 y ea rs, girls 9. 00± 1. 18 years) , velocity at take-off ( TOV) ( boys 4. 51± 0. 65 cm /year, girls 4. 95± 0. 79 cm /year) , age at peak height velocity ( PHA) ( boys 13. 07 ± 1. 08 y ea rs, girls 11. 32± 1. 32 years) , peak height velocity ( PHV) ( boys 10. 01± 1. 59cm /year, girls 8. 13± 1. 03 cm /year) , and age at endpoint ( EA) ( bo ys 16. 18± 1. 02 y ea rs, girls 13. 96± 1. 09 yea rs) . Correlation between final height and indices on growth velocity in the group was analyzed. It was a middle degree correlation between final height and the height at take-off age, and the peak age too. Final height significantly correlated with the height at endpoint age. The results of this study were also compared with research data from other sources.
