摘要
目的探讨不同孕前体质量指数(pre-pregnant body mass index,p BMI)妇女孕中晚期人体成分变化特点。方法采用多中心队列研究设计,以多频生物电阻抗技术检测孕妇孕中、晚期的去脂体质量(free fat mass,FFM)、肌肉重(muscular mass,MM)、体脂(fat mass,FM)、体脂百分比(fat mass percentage,FMP)、总体水(total body water,TBW)、细胞外液(extracellular water,ECW)和细胞内液(intracellular water,ICW)等成分。按p BMI将孕妇分为消瘦组202例(p BMI<18.5 kg/m^2)、正常组738例(18.5 kg/m^2≤p BMI<24 kg/m^2)、超重组117例(24 kg/m^2≤p BMI<28 kg/m^2)和肥胖组32例(p BMI≥28 kg/m^2)共四组,分析比较孕中晚期各项人体成分变化值的差异。结果整个孕中晚期,4组的FFM、MM、ECW、ICW和TBW变化值差异均无统计学意义(P>0.05)。肥胖组FM增加(2.46±4.34)kg,显著低于其他3组(P<0.05);各组间FMP增加程度均有统计学差异(P<0.01),并随p BMI增大而依次减少。结论不同p BMI孕妇孕中晚期去脂体质量增加无差异,而体脂百分比变化明显。
Objective To investigate changes of body composition of pregnant women with different level of pre-pregnant body mass index（p BMI） in the second and third trimester. Methods Prospective cohort study design was adopted in this study. The free fat mass（FFM）, muscular mass（MM）, fat mass（FM）, fat mass percentage（FMP）, total body water（TBW）, extracellular water（ECW） and intracellular water（ICW） were analyzed by multi-frequency bioelectrical impedance analysis. The body composition and its increases in the last two trimesters were compared among different p BMI groups including thin group（n=202, p BMI 18.5 kg/m^2）, normal group（n=738, 18.5 kg/m^2≤ p BMI 24 kg/m^2）, overweight group（n=117, 24 kg/m^2≤ p BMI 28 kg/m^2） and obesity group（n=32, p BMI ≥ 28 kg/m^2）. Results The changes of FFM, MM, ECW, ICW and TBW showed no significant difference in the four groups（P 0.05）. The growth of FM in the obesity group was（2.46±4.34） kg which was significantly lower than other groups（P 0.05）. There was significant difference in the increase of FMP in four groups and it reduced with the increase of p BMI level（P 0.01）. Conclusion The growth of FFM in the last two trimesters shows no differences in 4 groups, however the FMP changes are obviously different in the pregnant women with different p BMI.
