| Research Abstract |
The purpose of this study was to find out the patterns of sleep cycle of women during prenatal and postpartum period by using ME and survey the characteristics of subjective estimation on their sleep.
Nocturnal sleep recordings (EEG,EOG,EMG,and ECG) during 3 consective nights were made in seven women 11 to 37 weeks of pregnancy, four women 1 to 7 weeks of postpartum period, and four nonpregnant women. The pregnant group resulted in lower sleep efficiency compared to nonpregnant group. The sleep efficiency in the third trimester was lower than that in the first and second trimester. There was a negative relationship between pregnant women's gestation and percent Stage 4. Compared to the third trimester, sleep efficiency was lower and percent Stage 4 was increased in early postpartum period.
Subjective estimation form was developed including 3 major categories, namely, "Factors Relating to Sleep","Factors Relating on Awaking Feeling","Satisfaction resulting from Sleep". In order to identify the changes on sleep pattern during pregnancy and early postpartum period,289 pregnant womenand 86 mothers were studied.
It was found that in the first trimester the desire for sleep was stronger than the second and third trimester. Towards the third trimester, feeling of difficult to fall asleep, insufficient length of sleep, awaking during sleep were increased, and as a result, dissatisfaction with sleep increased. In the early postpartum period, the reasons awakened were shifted from woman's self-related factors to factors related to neonate. The sleep during the postprtum period was worse than the third trimester and above all, mothers were dissatisfied about their sleep.
Among the primigravidae, rejective feeling to the awaking during sleep was strong in the first trimester, but gradually decreased toward second, third trimester, and postpartum period. While the ratio of rejective feeling of the multigravidae was just the same with that of the third trimester of the primigravidae.
