大连汉族学生足长、足围与体重关系的研究

Study on the Relation between the Pedal Length and Circumference and Body Weight in Dalian Han Nation Students

目的：了解大连汉族学生足长、足围与体重的关系。方法：采用邵象情的人体测量学方法，调查了大连7～17岁1196名（男591，女605）汉族学生的体重、足长和足围，并研讨了足长、足围与体重的回归关系。结果：大连汉族学生的足长、足围和体重均随年龄的增长而增加，体重平均年增长值男性为3．6kg，女性为3．1kg；足长平均年增长值男性为0．65cm，女性为0．50cm；足围平均年增长值男性为0．51cm，女性为0．37cm。由足长推算体重的回归方程：男性是y＝5．33x－76．806，女性是y＝5．455s－76860。由足围推算体重的回归方程：男性是y＝6．479x－95．260，女性是y＝7．061s－101．937。结论：大连汉族学生足长、足围与体重之间存在正相关关系。

Objective: To study the relation between the pedal length and circumference and body weigh of Han nation students in Dalian. Method:According to Shao Xiangqing standard anthropometic method, we researched the body weight and pedal length and circumference of 1196(boys 591,girls 605 )Han nation students whe live in urban area of Dalian, and studied the relation of regression between the pedal length and circumference and they weight. Results: The they weight, pedal length and circumference of students increased with age. The increased values in a year included: body weight was 3. 61 kg for girls, pedal circumference was 0. 51cm for boys and 0. 37cm for girls. The regression equation from pedal circumference to calculate body weight(pedal circurnference = X, body weight = Y)was boys: Y = 6. 479X - 95. 260, girls: Y = 7. 061X - 101. 937. Conclusion: There was a positive proportion between the pedal length and circamference and body weight of Delian Han nation students.
