2014年与2010年兰州市7~18岁学生身体形态比较分析

Comparison and Analysis of the Physical Formof Students Aged 7-18 in Lanzhou in 2014 and 2010

为了解兰州市中小学生身体形态发展变化状况,抽取2010年与2014年两次学生体质监测资料进行比较,发现城乡男、女平均身高、平均体重、平均胸围、BMI值均有增加,其中城市男女的平均身高增长值差异显著(P<0.05);平均体重除城男外均有统计学意义(P_均<0.01);而乡男、城女的平均胸围为增长,城男、乡女却为负增长,无统计学意义;BMI值除城男外,均具非常显著性(P<0.01).但是,兰州市接近成人的18岁城男和17岁乡女的身高、胸围指标均呈负增长.可见兰州市学生身体形态的城乡差异有拉大的趋势,需引起足够重视.

In order to investigate the status of physical form of students in middle and primary schools,in Lanzhou city,the physical monitoring data of students in 2010 and 2014 were taken for comparison.The results showed that the average height,weight,chest circumference and BMI of male and female students in urban and rural areas increased,and the average height of male and female students in urban areas was significantly different(P<0.05).The mean body weight was statistically significant except for urban males(P<0.01).While the average chest circumference of rural male and urban female increased,that of urban males and rural females decreased with no statistical significance.BMI were very significant except for urban males(P<0.01).However,the height and chest circumference of 18-year-old urban males and 17-year-old rural females who were close to adults in Lanzhou showed negative growth.It was proved that the difference between urban and rural areas in the physical form of students in Lanzhou was increasing,which should be paid enough attention to.
