We prospectively recorded placental site, maternal weight and parity in 182 patients reporting decreased fetal movements and compared these with controls. Reports of decreased fetal movements were 2.10 times (95% CI 1.51-2.92) as likely in association with an anterior placenta and 1.81 times (95% CI 1.20-2.93) and 2.61 times (95% CI 1.26-5.40) as likely in mothers weighing over 80 and 90 kg, respectively, but there was no association with parity. Decreased perception of fetal movements is more likely to have serious implications in thin women with a posterior placenta. Our findings also suggest that the sensation of fetal movements arises from pressure against body wall structures rather than the uterus or peritoneum.
我们前瞻性地记录了182例报告胎动减少的患者的胎盘位置、孕妇体重和产次，并将这些数据与对照组进行比较。与前置胎盘相关的胎动减少报告可能性为2.10倍（95%置信区间1.51 - 2.92），体重超过80千克和90千克的母亲中，胎动减少报告可能性分别为1.81倍（95%置信区间1.20 - 2.93）和2.61倍（95%置信区间1.26 - 5.40），但与产次无关。胎盘后置的瘦女性中，胎动感知减少更可能产生严重影响。我们的研究结果还表明，胎动感觉源于对体壁结构的压力，而非子宫或腹膜。
