这项研究调查了怀孕后半期的生理和心理功能的轨迹，并比较了怀孕和非怀孕妇女对实验室压力源的反应。对137例妊娠20、24、28、32、36和38周的孕妇进行监测，包括测量心动周期（HP）、心动周期变异性（HPV）、皮肤电导（SCL）、呼吸周期（RP）、呼吸性窦性心律失常（RSA）和自我报告的情绪障碍。HP和RSA在此期间下降，SCL和情绪障碍增加。奇偶性是一个重要的调节因素。HP和SCL的Stroop色词任务的反应进行了两次评估，在怀孕的参与者和27个非怀孕妇女的样本进行了比较。孕妇的生理反应性降低。孕妇认为Stroop更难，但表现不受影响。尽管缓冲反应压力刺激在怀孕期间，提前妊娠与交感神经紧张和副交感神经紧张的上升下降。(c)2004 Elsevier B.V.保留所有权利。
This study investigated the trajectory of physiological and psychological functioning during the second half of pregnancy and compared responsiveness to a laboratory stressor between pregnant and non-pregnant women. Monitoring of 137 pregnant women at 20, 24, 28, 32, 36, and 38 weeks of pregnancy included measures of heart period (HP), heart period variability (HPV), skin conductance (SCL), respiratory period (RP), respiratory sinus arrhythmia (RSA), and self-report of mood disturbance. HP and RSA declined during this period; SCL and mood disturbance increased. Parity was a significant moderator. HP and SCL responsiveness to the Stroop color-word task was assessed twice in pregnant participants and compared to a sample of 27 non-pregnant women. Physiologic responsiveness was reduced in pregnant women. Pregnant women perceived the Stroop to be more difficult, but performance was unaffected. Despite buffered responsivity to stressful stimuli during pregnancy, advancing gestation is associated with escalating sympathetic tone and declining parasympathetic tone. (c) 2004 Elsevier B.V.
