广西壮族大学生皮下脂肪厚度的调查研究

Study on the thickness of subcutaneous fat from college sdudents of Guangxi Zhuang Nationality

调查 19～ 2 2岁壮族大学生 64 9人 (男 375人 ,女 2 74人 )的肱三头肌部、肩胛下角部和腹部的皮下脂肪厚度。结果表明 :男、女肱三头肌部及男肩胛下角部 19岁最大 ,2 2岁最小 ;女肩胛下角部 2 0岁最大 ,2 2岁最小 ;男、女腹部 2 2岁最大 ,19岁最小。男女间比较 ,女厚于男 ,差异有高度显著性 (P <0 .0 1)。皮下脂肪厚度与身高、体重的相关系数为男 -0 .72～ -0 .0 7、0 .0 4～ 0 .50 ,女 -0 .0 9～ 0 .2 4、0 .2 6～ 0 .58。

A study has been made on the thickness of the skinfolds of brachial triceps muscle, of inferior angle of scapula and of abodomen from 649 college students (males 375, females 274) of Zhuang Nationality, aged from 19 to 22. It indicates that the skinfolds of brachial triceps muscle in patients (males and females) and the male subscapular reach their biggest size at the age of 19, and smallest at 22. The female subscapular reaches its biggest at 20, and smallest at 22. The thickness of the abodomen fat ( both males and females ) reaches its biggest at 22, and smallest at 19. The fat of these parts of the females are thicker than those of the males. The difference was statistically signifficant ( P <0.01). The correlation coefficient of the thickness of substaneous fat and the body weight and height were respectively as the following: male (-0.72～-0.07, 0.04～0.50), female(-0.09～0.24, 0.26～0.58).
