摘要: 目的 探讨女童青春期线性生长与性发育时相的定量关系,为青春期身高评价提供参考依据。方法 采用分层随机整群抽样的方法,对北京市城区和郊区的9 630名6~19岁女童进行横断面调查,内容包括身高、体重、第二性征和月经初潮年龄,采用Person相关方法分析性发育与身高的相关性、t检验和方差分析方法比较各个性发育时相身高的差别。结果 1)性发育进程与身高水平呈正相关,尤其9~12岁更为明显(相关系数为0.41~0.55)。2)处于性发育不同时相的同龄儿身高存在明显差别,如8~12岁性发育前期者比性发育中期者身高平均低5~7 cm、11~13岁性发育中期者比同龄性发育后期者平均低4~6 cm;按年龄别身高标准计算身高百分位数值,性发育前期比性发育中期身高低约17~27个百分位,中期比后期低13~23个百分位。3)与未考虑性发育特征的身高曲线比较,8~9岁性发育处于中期、10~12岁性发育处于后期的女童,其身高明显高于相同年龄的平均身高约12~24个百分位;而10~11岁性发育前期、12~13岁性发育中期者身高明显低于同龄女童平均身高约10~30个百分位。结论 处于性发育不同时相的同龄女童身高存在明显差别,应用生长曲线图进行身高评价可根据性发育时相上调或下调一条曲线粗略校正性发育对身高的影响。

Abstract: Object To describe the quantitative relationship between puberty phases and height for Girls which could supply reference for assessment of linear growth. Methods A cross-sectional survey for 9 630 girls aged 6~18 years old was conducted in urban and suburban areas of Beijing by using the method of stratified random cluster sampling.Height,weight,secondary sexual characteristics were measured and age at menarche was obtain by questionnaire.The Methods of Pearson was used to describe the relationship between puberty phases and height and the ANOVA and t test were used to analyze the difference of height in different puberty phases. Results 1)There was positive correlation between sexual development and height,especially in the 9~12 years old (correlation coefficient 0.41~0.55).2) The difference of height among different puberty phases were obvious:At 8~12 years,height of pre-puberty was 5~7cm shorter than that of in-puberty for girls in the same age group.At 11~13 years,height of in-puberty was 4~6 cm shorter than that of completing-puberty for girls in the same age groups.The height percentiles of pre-puberty was 17~27 lower than that of in-puberty for girls in the same age group and that of in-puberty was 13~23 lower than that of completing-puberty for girls in the same age groups.3)Comparing the height of different puberty phases with that of ignoring puberty phases:the height centiles of in-puberty for 8~9 years girls and completing-puberty for 10~12 years girls was 12~24 higher than that of the same age girls,while the height centiles of pre-puberty for 10~11years girls and in-puberty for 12~13 years girls was 10~30 lower than that of the same age girls. Conclusions Height of different puberty phases in the same age group is different.The assessment Results of height by applying conventional growth curves could be added or subtracted one curves to correct the effect of puberty phase.
