目的：描述北美男孩目前的身高和青春期发育情况，并将这些测量方法与大约30年前的测量结果进行比较。方法：我们分析了1988-1994年进行的第三次全国健康与营养检查调查(NHANES III)的数据(即身高、体重和皮肤晒黑阶段)，并将其与1963-1965和1966-1970年进行的第二和第三次全国健康检查调查(HES II/III)进行了比较。调查包括体检和问卷调查，采用横断面设计，具有全国代表性。我们使用Logistic回归来计算青春期开始的中位年龄。结果：NHANES III包括2481名8至IS岁的男孩。HES II包括3010名8至11岁的男孩，HES III包括3514名12至17岁的男孩。两项调查中年龄最大的男孩的平均身高没有显著差异；然而，在较年轻的年龄，最近一次调查中的男孩更高(8-14岁儿童的平均身高差距为2.0厘米)。NHANES III的男孩体重和体重指数也高于HES II/III。NHANES III生殖器阶段2-5的青春期开始年龄中位数分别为9.9岁、12.2岁、13.6岁和15.8岁，阴毛阶段2-5岁分别为11.9岁、12.6岁、13.6岁和15.7岁。在某些阶段，NHANES III的男孩估计青春期开始年龄的中位数早于HES III的男孩。结论：NHANES III男孩的平均身高在年轻年龄时的差异，而不是在较大年龄的差异，表明NHANES III男孩的生长速度快于早期调查的男孩。这一发现，再加上一些青春期阶段开始年龄更早的发现，表明这一代男孩可能比过去的男孩成熟得更快。(C)青春期医学会，2002年。
Purpose: To describe current stature and pubertal development in North American boys, and to compare these measures with measures observed approximately 30 years ago.Methods: We analyzed data (i.e., height, weight, and Tanner Stage) from the Third National Health and Nutrition Examination Survey (NHANES III), conducted between 1988-1994, and compared it to the National Health Examination Survey, Cycles II and III (HES II/III) conducted from 1963-1965 and 1966-1970. The surveys included physical examination and questionnaire components, employed cross-sectional designs, and are nationally representative. We used logistic regression to calculate median age at onset of pubertal stages.Results: NHANES III included 2481 boys aged 8 to IS years. HES II comprised 3010 boys aged 8-11 years and HES III comprised 3514 boys aged 12-17 years. The mean heights of the oldest boys in both surveys did not differ significantly; however, at younger ages, boys in the more recent survey were taller (average height difference among those aged 8-14 years was 2.0 cm). Boys in NHANES III were also heavier and had higher body mass index than those in HES II/III. The median estimated ages of onset of pubertal stages in NHANES III were 9.9, 12.2, 13.6, and 15.8 years for genital stages 2-5, respectively, and 11.9, 12.6, 13.6, and 15.7 years for pubic hair stages 2-5, respectively. For some stages, the median estimated age of onset of puberty was earlier among boys in NHANES III than among those in HES III.Conclusions: Differences in mean height at young ages, but not at older ages, suggest that the rate of growth among boys in NHANES III was faster than that of boys in the earlier surveys. This finding, coupled with the finding of earlier ages of onset of some pubertal stages, suggests that boys of this generation may be maturing more rapidly than did boys in the past.
