妊娠期妇女的人体测量及脂肪贮存

本文对30名居住北京城近郊区的健康初产孕妇,于妊娠早期、中期及末期连续进行人体测量,包括身长,体重,皮下脂肪厚度和肢体围,以观察孕期体重增长,身体脂肪含量及肌肉情况。测量结果,受试者从妊娠6周至37周平均体重增长13.0kg。三头肌、二头肌部位皮脂厚度在孕期无明显变化。肩胛下皮脂厚度至孕末期时明显较早期增加。髂骨上皮脂厚度在孕中期及末期均有明显增长,与早期相比差別显著。据皮脂厚度计算身体密度及脂肪含量络果,至孕末期身体脂肪含量占体重的百分比共增加3.7％。肢体围测量结果,仅臀围在妊娠中期后至末期明显较早期增大。大腿上部围略有增加,但与早期差别无显著意义。大腿中部、小腿腓肠肌部及上臂围孕期均无明显变化。

ANTHROPOMETRY AND FAT STORE DURING PREGNANCY

Weight gain, skinfold thickness, circumference and body density were measured in 30 primiparous women aged from. 23-31 years (averaged 26.3 years old).The average body weight gained 13kg from 6 to 37 weeks of pregnancy.The suprailiac skinfold thickness in 24-37 weeks and the subscapular skinfold thickness in 37 weeks increased significantly from the 6th week of pregnancy, but the triceps and biceps skinfold thickness did not change significantly. The density of the body in 24th and 37th week of pregnancy decreased significantly.The change and the body fat (%) calculated by means of 4 skinfolds increased in 3.7% (5.7kg of fat). The mean values of the hip circumference in 24th and 37th week were significantly different from that in 6th week of pregnancy. The upper thigh in the 24th and 37th week also increased slightly but not significantly different as compared with the 6th week. The mean values of arm, mid-thigh and calf circumference did not change during pregnancy.
