众所周知，青春期的时间对人体测量和心理社会结果有影响。多种方法已被用于确定青春期的时间，但都有局限性。对于不同的研究设计和研究人群，需要一种统一适用的方法。本研究的目的是：（1）提出一种利用统计模型确定青春期发育相对时间的新方法：（2）通过评估青春期发育与时间参数（初潮年龄、乳晕发育开始年龄、身高增长速度峰值年龄、成年身高达到年龄、成年身高、身高增长速度峰值年龄、BMI和体脂百分比）的关系来验证新方法的有效性;（3）将新方法与相对初潮时间对这些青春期参数的影响进行对比。使用国家心肺和血液研究所生长和健康研究（NGHS）的数据，有序逻辑模型被用来评估青春期成熟的相对时间。所提出的方法表现出良好的可靠性和强关联性与所有青春期的时间参数，也BMI和体脂百分比。时间与成人身高和峰值身高速度无显著相关性。该方法可行性强，易于实现，有效性高。研究表明，第二性征的相对时间和初潮时间对青春期参数的关系之间存在重要差异。这项研究还表明，在一个时间点上具有早期或晚期定时的个体可能在整个青春期保持相同的相对定时。
The timing of puberty has well known impact on anthropometric and psychosocial outcomes. Multiple methods have been used to determine pubertal timing, but all with limitations. A uniformly applicable method is needed for different study designs and study populations. The objectives of the study are 1) to propose a new method using statistics modeling to determine relative timing of pubertal maturation; 2) to validate the new method by evaluating its relationship with pubertal growth and timing parameters, including age at menarche, age onset of areolar maturation, age of peak height velocity, age at attainment of adult height, adult height, peak height velocity, BMI and percent body fat; and 3) to contrast the new method with relative timing of menarche on these pubertal parameters. Using the National Heart Lung and Blood Institute Growth and Health Study (NGHS) data, an ordinal logistic modeling was used to assess relative timing of pubertal maturation. The proposed method demonstrated good reliability and strong associations with all pubertal timing parameters, also BMI and percent body fat. Timing was not significantly associated with adult height and peak height velocity. The proposed method is highly feasible, easy to implement, and valid. The study demonstrated important differences between the relationships of relative timing of secondary sexual characteristics and the timing of menarche on pubertal parameters. The study also demonstrates that individuals with early or late timing at one point of time are likely to maintain the same relative timing throughout puberty.
