This study identifies the mean and standard deviations of the chronological age of the attainment of a variety of important events of puberty in American males and females. The information is based on longitudinal observations at 6-month intervals with the first observation of each particular pubertal characteristic being documented within 6 months of its appearance. The mean (+/- SD) ages of pubic hair and genital or breast stages, and onset of peak weight gain, peak height velocity, acne and axillary hair are given for both sexes. Menarche is documented for females, and gynecomastia, voice break and change, and facial hair for males. These data show the range of individual age variation of normal pubertal events. Puberty may begin from age 8.0 to 14.9 years for females and from age 9.7 to 14.1 years for males and is complete by age 12.4 to 16.8 years for females and by age 13.7 to 17.9 years for males.
本研究确定了美国男性和女性青春期各种重要事件发生时的实际年龄的均值和标准差。这些信息基于每隔6个月进行的纵向观察，每个特定青春期特征首次出现后6个月内记录其相关情况。给出了两性阴毛和生殖器或乳房发育阶段、体重增加峰值开始、身高增长速度峰值、痤疮和腋毛出现时的平均（±标准差）年龄。记录了女性的月经初潮，以及男性的乳腺增生、声音突变和变化、面部毛发情况。这些数据显示了正常青春期事件个体年龄变化的范围。女性青春期可能始于8.0至14.9岁，男性始于9.7至14.1岁，女性在12.4至16.8岁完成，男性在13.7至17.9岁完成。
