Tanner发育阶段女生自评现状及其与相对青春发动时相的相关性分析

目的:调查小学四年级至初中三年级女性学生Tanner发育阶段自评现状，并探讨Tanner发育阶段和相对青春发动时相的相关性。方法:采用分层随机整群抽样法抽取蚌埠市5所学校小学四年级至初中三年级共1 113名女性学生，采用Tanner发育阶段自评图和相对青春发动时相问卷进行调查。结果:Tanner发育阶段指标中，乳房发育TannerⅡ、Ⅲ、Ⅳ期P₅₀年龄分别是9.71、12.06、15.03岁，阴毛发育TannerⅡ、Ⅲ、Ⅳ期P₅₀年龄分别是10.99、12.39、14.98岁。月经初潮P₅₀年龄是11.71岁。Tanner发育阶段（乳房、阴毛、月经）与相对青春发动时相各指标间均呈显著正相关关系（P<0.01）。结论:自我评定Tanner发育阶段青春发动的顺序为首先出现乳房发育，然后开始阴毛发育，最后出现月经初潮，自我评定的Tanner发育阶段与相对发动时相具有一致性。

The self-rating status of girl in pubertal Tanner stage and its correlation with relative pubertal timing

Objective: To investigate the self-rating status of girls in pubertal Tanner stage from grade 4-6 in primary schools and grade 1-3 in junior high schools,and its correlation with relative pubertal timing.Methods: A total of 1 113 girls from grade 4 to grade 9 of five schools in Bengbu city were sampled using stratified random cluster sampling,and investigated using the pubertal Tanner stage assessment and relative pubertal timing questionnaire.Results: Among the each indicator of pubertal Tanner stage,the median ages of breast Tanner Ⅱ、Ⅲ、Ⅳ stage were 9.71,12.06 and 15.03 years old,respectively,and the median ages of pubic hair Tanner Ⅱ、Ⅲ、Ⅳ stage were 10.99,12.39 and 14.98 years old,respectively.The median age of menarche was 11.71 years old.There was a significantly positive correlation between each indicator of relative pubertal timing and pubertal Tanner stage assessment(including breast,pubic hair and menstruation)(P<0.01).Conclusions: The order of onset of puberty during Tanner's developmental stage is breast development,then pubic hair development,and finally menarche,and the self-rating of pubertal Tanner stage is consistent with relative pubertal timing.
