目的了解湖北省农村中学生身体形态的变化趋势,为制定农村学校体育卫生工作方针提供科学依据。方法以参加1985,1995,2005年全国学生体质健康调查研究的湖北省农村13～18岁男、女中学生共9417名为研究对象,对各年龄组男、女生的身高、体重、胸围等形态指标进行统计学分析。结果1985-2005年湖北省农村男、女中学生身高均有显著增长;农村中学男生体重增长显著,女生除13～14岁体重有所增长外,其他年龄组体重均无明显增长,后10a女生体重处于停滞状态;农村中学生的胸围发育情况不容乐观,只有初中男生的胸围有所增长,17～18岁女生的胸围显著减小。结论近20a来湖北省农村中学男生的形态发育状况好于女生,但男生胸围的发育落后于身高、体重的发育,女生的体重、胸围的发育均落后于身高的发育。应尽快将健康干预的重点放到农村,促使农村中学生尽快赶上城市中学生的形态发育水平。
Objective To understand the changing trend of the body shape of rural middle school students in Hubei Province and to provide a scientific basis for formulating the rural school sports health guidelines. Methods A total of 9,417 male and female secondary school students from 13 to 18 years old in rural areas of Hubei Province were enrolled in the National Student Health Survey in 1985, 1995 and 2005. The body height, weight, bust and other morphological indexes of male and female students in all age groups Statistical analysis. Results The height of male and female middle school students in rural areas of Hubei province increased significantly from 1985 to 2005. The weight of boys and middle school students in rural areas increased significantly. Except for 13 to 14 years of age, the female students gained no significant weight gain. In a stagnant state; bust development in rural middle school students is not optimistic, only the bust of junior high school boys increased, the bust of 17 to 18-year-old girls significantly reduced. CONCLUSIONS: In recent 20 years, the male students in rural middle schools in Hubei Province have better morphological development than girls. However, the development of boys’ bouts lags behind the growth of height and weight. The body weight of girls and the development of busts lag behind the development of height. As soon as possible, the focus of health intervention should be placed on rural areas, prompting rural middle school students to catch up with the urban middle school students’ morphological development as soon as possible.
