Outline of Final Research Achievements

Objective: To elucidate characteristic sleep structure of different nocturnal sleep patterns in early infancy. Designs: Infants’ nocturnal sleep was monitored simultaneously using actigraphy and one-channel electroencephalography (EEG) at the age of 3-4 months. Each night’s sleep pattern was classified into three categories.
Results: Analysis was conducted during 95 nights in 27 infants. The STN pattern (sleeping through the night,n=36) was characterized by suppressed body movements while EEG represented a state of wakefulness. The weak signal pattern(crying/fuss episodes <10 minutes or fed, n=27) tended to indicate rich and regular distributions of SWS across the night. The strong signal pattern (crying/fuss episodes≧10 minutes)n=32) was characterized by reduced sleep time, although the amount of SWS was not reduced to that degree. Exclusive breastfeeding may increase the proportion of SWS in non-REM sleep.
