摘　　要：目的探讨描述生长发育长期趋势的适宜指标,并通过比较选择适宜的时间跨度。方法根据大连市1948-2008年10个时间点的城市高中男生的身高、体重、胸围资料,选取短至5 a、长至17 a的不同时间跨度,计算"年增长率"(‰)。结果以身高为例,1959-1963年(5 a跨度)的年增长率为-5.64‰,1959-1974年(16 a跨度)的年增长率为0.98‰;除特殊时期1959-1963年外,以10 a左右的时间跨度来计算,"年增长率"分布在0.64‰～4.10‰,以5 a左右为时间跨度计算,分布在0.64‰～2.78‰。结论描述生长发育长期趋势,宜于采用年增长率这个相对数,时间跨度以10 a为宜;若出现重大营养问题,采用5 a的跨度更为敏感。Objective To explore reasonable indexes for describing growth and development long-term trend, and to choose reasonable time span （ TS） by compare. Methods Annual growth rate （ AGR ） were calculated in different time spans from 5 - 17 years according to urban high school male students height, weight and chest circumference data which was got in 10 time points from1946 to 2008 in Dalian. Results Taking height as example, AGR of 1959 - 1963 （ TS = 5a） was -5.64‰, while AGR of 1959 - 1974 （ TS = 16a） was 0.98‰. Except 1959 - 1963, the AGRs were 0.64‰ - 4.10‰ when TS was around 10 years, while they were 0.64‰ - 2.78‰ when TS was around 5 years. Conclusion Relative number AGR is fit for describing growth and development long-term trend, and 10a may be fitting TS. However, if serious nutritive problem appoared, 5a may be more sensitive.
