中日学生足长、足围与身高关系的比较研究

A comparison on the relation between foot length and girth and stature of students in China and Japan

目的 研究中日学生足长、足围与身高关系的差异性。方法 采用国际通用的人体测量学方法,调查了大连7～17岁1 209(男599,女610)名汉族学生和东京7～12岁272(男133,女139)名学生的身高、足长和足围,并着重研讨了足长、足围与身高的关系。结果 足长、足围与身高之间存在正相关关系。(1)由足长推算身高的回归方程:大连男性为Y=6.836x-2.83,女性为Y=7.611x-15.280;东京男性为Y=5.852x+12.132,女性为Y=6.683X-3.730。(2)由足围推算身高的回归方程:大连男性为Y=7.518X-9.292,女性为Y=8.355X-20.069;东京男性为Y=6.104X+9.045,女性为Y=5.888X+15.630。(3)由身高推算足长的回归方程:大连男性为Y=0.129X+2.944,女性为Y=0.111X+5.040;东京男性为Y=0.147X+1.050,女性为Y=0.127X+3.625。(4)由身高推算足围的回归方程:大连男性为Y=0.099X+6.383,女性为Y=0.079X+8.440;东京男性为Y=0.123X+3.959,女性为Y=0.114X+4.755。结论 足长、足围与身高之间存在正相关性,中日学生回归方程间有差异。

Objective To study on the differnece of relation between foot length and girth and stature of students in China and Japan. Methods According to the international standard of anthropometic method, we researched the stature and foot length and girth of 1209 (boys 599, girls 610) Han nation students aged from 7-17 years old who live in urban area of Dalian and 272 (boys 133, girls 139) Tokyo students aged from 7-12 years old, and researched relation of regression between the foot length and girth and stature. Results The results showed that there was a positive proporion between the foot length and girth and stature. (1) The regression equation from foot length to calculate stature (foot length= X, stature=Y): Dalian boys: Y = 6.836X-2.283, Dalian girls: Y = 7.611X-15.280; Tokyo boys: Y = 5.852X+ 12.132, Tokyo girls: Y=6. 683X-3.730. (2)The regression equation from foot girth to calculate stature (foot girth = X, stature = Y) : Dalian boys: Y = 7.518X-9.292, Dalian girls: Y = 8.355X-20.069; Tokyo boys: Y = 6.104X+ 9.045, Tokyo girls: Y = 5.888X + 15.630. (3)The regression equation form stature to calculate foot length (stature = X, foot length = Y): Dalian boys: Y = 0.129x + 2.944, Dalian girls: Y = 0.111X + 5.040; Tokyo boys: Y = 0.147X+1.050, Tokyo girls: Y = 0.127X +3.625. (4) The regression equation form stature to calculate foot girth (stature = X, foot girth = Y): Dalian boys: Y = 0.099X + 6.383, Dalian girls: Y = 0.079X +8.440; Tokyo boys: Y = 0.123X + 3.959, Tokyo girls: Y = 0.114X + 4. 755. Conclusion A positive proportion between the foot length and girth and stature. The difference of the regression equation between Chinese and Japanese students.
