This study examined the basal metabolic rate in patients with twin pregnancies and compared the results with those of singleton pregnancies and non-pregnant women.
In 15 non-pregnant women, 14 patients with twin and 25 patients with singleton pregnancies, the resting energy expenditure was measured using an open-circuit ventilatory system during the third trimester of pregnancy.
The averaged resting energy expenditure in patients with twin pregnancy was 1,636 +/- 174 kcal/day, significantly higher than that in patients with singleton pregnancy (1,456 +/- 158 kcal/day; p < 0.05). Both of these levels are significantly higher than those in non-pregnant women (1,228 +/- 132 kcal/day; p < 0.05).
Our results indicate that the estimated increased metabolic demands in patients during the third trimester of twin pregnancy are about 10% higher than those in women with singleton pregnancy. A prospective clinical study concerning nutrition counseling is needed.
本研究检测了双胎妊娠患者的基础代谢率，并将结果与单胎妊娠患者及未孕女性进行比较。
选取15名未孕女性、14名单胎妊娠患者和25名双胎妊娠患者，在妊娠晚期使用开路通气系统测量静息能量消耗。
双胎妊娠患者的平均静息能量消耗为1636±174千卡/天，显著高于单胎妊娠患者（1456±158千卡/天；p<0.05）。这两个水平均显著高于未孕女性（1228±132千卡/天；p<0.05）。
我们的结果表明，双胎妊娠晚期患者估计增加的代谢需求比单胎妊娠女性高约10%。需要进行一项关于营养咨询的前瞻性临床研究。
