The ages of onset of pubertal characteristics are influenced by genetic, geographic, dietary and socioeconomic factors; however, due to lack of country-specific norms, clinicians in Saudi Arabia use Western estimates as standards of reference for local children.
The aim of the Riyadh Puberty Study was to provide data on pubertal development to determine the average age of onset of pubertal characteristics among Saudi boys.
Cross-sectional study among male school children in Riyadh, Saudi Arabia, in 2006, 542 schoolboys, aged 6 to 16 years old, from diverse socioeconomic levels were selected into the sample using a cluster sample design. Tanner stages were ascertained during physical examination by pediatric endocrine consultants, and also trained pediatric residents and fellows.
The mean age (standard deviation) at Tanner Stages 2, 3, 4, and 5 for pubic hair development of Saudi boys was 11.4 (1.6), 13.3 (1.3), 14.4 (1.0) and 15.1 (0.8) years old, respectively. For gonadal development, the mean age (standard deviation) at stages 2, 3, 4, and 5 were 11.4 (1.5), 13.3 (1.2), 14.3 (1.1) and 15.0 (0.9) years old, respectively.
The ages of onset of pubertal characteristics, based on gonadal development, among Saudi boys are comparable to those reported in Western populations.
青春期特征的开始年龄受遗传、地理、饮食和社会经济因素影响；然而，由于缺乏特定国家的标准，沙特阿拉伯的临床医生将西方的评估结果用作当地儿童的参考标准。
利雅得青春期研究的目的是提供青春期发育数据，以确定沙特男孩青春期特征开始的平均年龄。
2006年在沙特阿拉伯利雅得对男学生进行横断面研究，采用整群抽样设计从不同社会经济水平的6至16岁542名男学生中选取样本。由儿科内分泌顾问以及经过培训的儿科住院医师和研究员在体格检查时确定坦纳分期。
沙特男孩阴毛发育达到坦纳2期、3期、4期和5期的平均年龄（标准差）分别为11.4（1.6）岁、13.3（1.3）岁、14.4（1.0）岁和15.1（0.8）岁。对于性腺发育，达到2期、3期、4期和5期的平均年龄（标准差）分别为11.4（1.5）岁、13.3（1.2）岁、14.3（1.1）岁和15.0（0.9）岁。
基于性腺发育，沙特男孩青春期特征开始的年龄与西方人群报告的年龄相当。
