摘要
We studied changes in the sleep patterns of ten young women from late pregnancy (36 weeks) to the sixth postpartum week, focusing on the relationship between the women's sleep patterns and their infants' movements. The mothers' polysomnograms and their infants' ankle actigrams were simultaneously recorded using a Medilog 9000 at home in three sessions, during the first, third, and sixth postpartum weeks. The mother-infant pairs slept in close proximity. Two subjects had difficulty with their infants and were dealt with as a separate group. Analysis for the eight subjects who adapted well to the postpartum period showed that wake lime after sleep onset increased significantly during the postpartum period compared with late pregnancy given responsibility for feeding. Stage 3+4 and Stage REM did nor change across the four sessions (pregnancy, first, third, and sixth postpartum weeks), but Stage 2 decreased significantly from pregnancy to postpartum. There was a high synchronization between infants' movements and mothers' wakefulness. Eight mothers did not complain of sleep disturbance, while the two mothers who had difficulty with their infants did. We suggest that mothers who tolerate well sleep interruption arising from feeding and maintain their Stages 3+4 and REM should not be considered as suffering from sleep disturbance. Mothers who have difficulty with their infants and complain of sleep disturbance should be considered as suffering from sleep disturbance.
