目的掌握本地区青少年学生的体质健康状况,探讨发展趋势,提高学校体育卫生工作水平。方法采用分层整群随机抽样方法,对7~17岁共计4976名中小学生进行了形态机能指标调查分析,并与1995年本地同类资料进行比较。结果生长发育的各项指标都随年龄增加而增加,发育速度呈波浪式。机能指标肺活量均值随年龄的增长而增加。7~17岁男、女生身高发育分别增长了4.08cm和1.87cm,与10年前比较差异有统计学意义(P<0.01);男、女生体重发育平均增加3.23kg和1.12kg,与10年前比较差异有统计学意义(P<0.01)。男女胸围发育22个年龄组中有5个年龄组胸围均值呈负增长,男生10年平均增长1.45cm,女生平均增长0.42cm。结论通过青少年学生形态指标监测,可以有效指导提高青少年体质的方法。
Objective To grasp the physical health status of young students in this area, discuss the development trend and improve the level of physical education and health work in schools. Methods A stratified cluster random sampling method was used to investigate the morphological and functional indexes of 4976 primary and middle school students aged 7-17 years and compared with the same kind of local data in 1995.

The height growth of male and female 7 ~ 17 years old increased by 4.08cm and 1.87cm, respectively, compared with 10 years ago (P <0.01). The average weight gain of male and female increased by 3.23kg and 1.12kg, Before the difference was statistically significant (P <0.01). The bust average of 5 age groups of 22 age groups was negatively increased. The male average growth rate was 1.45cm in 10 years and that of female students was 0.42cm.
