本文分析了青春期男孩和女孩身高增长的强度和持续时间与成熟节律的关系。对251名儿童进行了10 - 20岁的纵向临床随访，根据青春期开始的年龄分组：男孩生殖期2：11岁（n = 28）、12岁（n = 38）、13岁（n = 42）和14岁（n = 27）; 10岁（n = 37）、11岁（n = 47）、12岁（n = 19）和13岁（n = 13）的女孩（乳房2期）。每年测量身高。在男孩中评估睾丸体积和生殖器发育，在女孩中评估乳房发育。各成熟年龄组青春期开始时身高差异有显著性（P < 0.001）。晚熟组身高高于早熟组（女生r = 0.49，P < 0.001;男生r = 0.38，P < 0.001）。然而，最终的高度没有根据发病年龄在任何性别的差异。在男孩中，青春期开始较晚与青春期身高增加较小相关（r =-0.60，P < 0.001），青春发育期缩短女孩青春期开始早与青春期身高增长相关（r =-0.61，P < 0.001）（r =-0.68，P < 0.001）和较长的青春发育期（r =-0.59，P < 0.001）。总之，青春期开始的年龄不影响最终达到的高度在两种性别，因为有一个逆补偿现象，在两种性别之间的高度在青春期开始和青春期生长的强度和持续时间。 2001 Wiley-Liss，Inc.
This paper analyzed the intensity and duration of height growth during puberty in boys and girls in relation to rhythm of maturation. A longitudinal clinical follow-up between ages of 10 and 20 years, was carried out in a sample of 251 children grouped according to age at pubertal onset: boys (genital stage 2) at the ages of 11 (n = 28), 12(n = 38), 13 (n = 42), and 14 (n = 27); and girls (breast stage 2) at the ages of 10 (n = 37), 11 (n = 47), 12 (n = 19), and 13(n = 13). Height was measured annually. Testicular volume and genital development were assessed in boys, and breast development was assessed in girls. There were significant differences (P < 0.001) in height at the age of pubertal onset among maturity groups. Late maturers were taller than early maturers (r = 0.49, P < 0.001 for girls; r = 0.38, P < 0.001 for boys). However, final heights did not differ according to age of onset in either sex. In boys, later onset of puberty was associated with a smaller pubertal height gain (r = -0.60, P < 0.001) and a shorter period of pubertal growth (r = -0.61, P < 0.001), Equally in girls, earlier onset of puberty was associated with a greater pubertal height gain(r = -0.68, P < 0.001) and a longer period of pubertal growth (r = -0.59, P < 0.001). In conclusion, age of pubertal onset does not affect final height attained in both sexes, since there is an inverse compensatory phenomenon in both sexes between height at pubertal onset and the intensity and duration of pubertal growth. 2001 Wiley-Liss, Inc.
