| 目的 分析广东省中山市在校学生青春期身高增速高峰(PHV)及其身高增速高峰年龄(PHA)特征及变化趋势.方法 使用广东省中山市2005-2010年全市学生体检资料,计算年龄别生长速度、PHV、PHA及以PHA为基点的生长速度.结果 男生PHV为(10.03±1.67)cm/yr,女生为(8.39±1.05 )cm/yr,与国内外以往研究相近；男生PHA为(12.28±1.30)岁,女生为(10.78±1.04)岁,低于国内外以往的研究.身高水平与PHA的Pearson相关系数男生为-0.357(P＜0.001),女生为-0.338(P＜0.001).结论 青春期身高水平与PHA前的身高增速相关性较大.广东省中山市在校学生的PHA低于北京、沈阳、南京地区,也低于美国和英国,而PHV与中国其他地区及英美国家相近. |

| Objective To discuss characteristics of height growth such as Peak Height Velocity (PHV) and Age at Peak Height Velocity (PHA) during adolescence,and to compare the results with other research findings.Methods Primary and middle school students' annual physical examination data of Zhongshan in 2005-2010 was used.The height velocity by age,PHV,PHA,height velocity by PHA were calculated.Results The average peak height velocity boys was ( 10.03 ± 1.67 ) cm/yr.and that of the girls was ( 8.39 ± 1.05 ) cm/yr.Both findings were close to the results from previous similar findings.The average age at which peak height velocity reached 12.28± 1.30 years for boys and 10.78 ± 1.04 years for girls,both lower than the previous findings.The correlation coefficients,between height level and PHA were -0.357 (P＜0.001) for boys and -0.338 (P＜0.001) for girls.Conclusion The height levels were positively related to the height velocity before PHA.The Zhongshan students' PHA was lower than the Beijing,Shanghai and Shenyang students,also lower than American and Britain students',but their PHVs were similar. |
