To explore the applicability of pubertal development scale in estimating sexual maturation among urban Chinese adolescents.
A cross-sectional survey was conducted among 2562 students of 4(th) to 12(th) grade in Shanghai, selected by stratified cluster sampling method. Self-reported pubertal maturation level was obtained by Pubertal Development Scale (PDS). Meanwhile, visual depiction of Tanner stages of breast, genital and pubic hair development were rated by a trained rater of the same gender.
In 2562 students, the correlation between self-reported PDS and assessment from the raters were substantial, both in boys and girls (Pearson's correlation coefficients: 0.822 and 0.814, respectively). The overall agreement of pubertal development stages based on PDS and the rater's assessment were 35.24% and 51.42% for boys and girls, respectively, with Kendall's correlation coefficients as 0.713 and 0.685, respectively. Adolescents who were older, had relatively higher level of pubertal stages or adolescents from the richer families, tended to underestimate their actual level of pubertal maturation while those male subjects and overweight or obese subjects were even more likely to be so.
Using the self-reported PDS, we could conveniently obtain the necessary information regarding sexual maturation among the urban adolescents. It seemed especially useful in the related epidemiological survey when physical examination was precluded by cost, privacy and other concerns.
探讨青春期发育量表在中国城市青少年性成熟评估中的适用性。
采用分层整群抽样方法，对上海市2562名四至十二年级学生进行横断面调查。通过青春期发育量表（PDS）获取自我报告的青春期成熟水平。同时，由同性别经过培训的评估者对乳房、生殖器和阴毛发育的坦纳分期进行视觉评定。
在2562名学生中，自我报告的PDS与评估者评估之间的相关性在男孩和女孩中均很显著（皮尔逊相关系数分别为0.822和0.814）。基于PDS和评估者评估的青春期发育阶段总体一致性在男孩和女孩中分别为35.24%和51.42%，肯德尔相关系数分别为0.713和0.685。年龄较大、青春期阶段水平相对较高或来自富裕家庭的青少年往往低估其实际青春期成熟水平，而男性受试者以及超重或肥胖受试者更有可能如此。
使用自我报告的PDS，我们可以方便地获取城市青少年性成熟的必要信息。当由于成本、隐私和其他问题无法进行体格检查时，它在相关流行病学调查中似乎特别有用。
