Auxological measurements were taken weekly (n = 10), semi-weekly (n = 20), and daily (n = 3) during the first 21 months of life on a sample of normal infants (21 females and 12 males). The serial length measurements are reported. All subjects grew in length during episodic growth saltuses of short duration, with amplitudes of 0.5-2.0 cm during measurements intervals (1 day to 1 week), separated by periods of no measurable growth (2 days to 2 months). The periods of stasis between growth episodes are not positively associated with illness (P = 0.000). These data support the hypothesis that normal human growth during the first 2 years proceeds by pulsatile growth saltuses of substantial amplitude and rapid duration punctuating static intervals. Individual variability in the amplitude and frequency of growth saltuses may account for variation in attained length and growth velocity. © 1993 Wiley-Liss, Inc.
对一组正常婴儿（21名女性和12名男性）在出生后的前21个月进行了人体测量，测量频率分别为每周一次（n = 10）、每半周一次（n = 20）和每天一次（n = 3）。报告了连续的身长测量数据。所有受试者在短时间的阶段性生长突增期身长均有增长，测量间隔（1天至1周）内的增幅为0.5 - 2.0厘米，期间穿插着无明显生长的时期（2天至2个月）。生长突增期之间的停滞期与疾病无正相关（P = 0.000）。这些数据支持了这样一种假设，即人类在出生后前两年的正常生长是由幅度较大且持续时间较短的脉冲式生长突增期间断性地穿插在静止期进行的。生长突增期的幅度和频率的个体差异可能解释了身长和生长速度的差异。© 1993威利 - 利斯公司。
