“…There was no significant correlation between night and day sleep durations at M0 or M6 (p>0.25). As already published before [14], compared to day sleep, night sleep was significantly longer and more efficient at both M0, but especially at M6 at which time there was also a significantly greater proportion of quiet sleep (QS) and a significantly smaller proportion of active sleep (AS). There were also significantly more arousals in AS during day sleep at M0 and during night sleep at M6.…”

Background. Few studies on the relationship between sleep quantity and/or quality and cognition have been conducted among preschoolers from the healthy general population. We aimed at identifying, among 3-year-old children, early polysomnography (PSG) sleep factors associated with intelligence quotient (IQ) estimated using the Weschler Preschool and Primary Scale Intelligence-III test (WPPSI-III) and its indicators: full-scale (FISQ), verbal (VIQ), and performance (PIQ) intelligence quotients. Methods. We included full-term children from the French birth-cohort AuBE with both PSG recording at term (M0) or 6 months (M6) and available WPPSI-III scores at 3 years. Sleep and arousal characteristics of these infants were evaluated during day and night sleep periods. Relationships between IQ scores and sleep parameters were estimated using models with child as repeated effect adjusted for time (night/day), maturation (M0/M6), tobacco exposure (yes/no), anxiety depressive scores during pregnancy, maternal age, duration of breastfeeding and child gender. Results. A total of 118 PSG recordings were included, representing a total 78 unique children (38 with one PSG and 40 with 2 PSG). No correlations were found between night and day sleep durations at M0 or M6. Mean VIQ, PIQ, and FSIQ scores were within normal ranges. In multivariate models, longer sleep duration, higher sleep efficiency during day were negatively associated with all IQ scores. More frequent arousals during night were associated with lower VIQ scores. Conclusion. Early sleep characteristics such as night sleep fragmentation or longer naps could be associated with impaired cognitive function at 3 years of age.

“…Arguing that no difference exists in the maturation of arousals during the nychthemere, different authors have conducted studies to investigate SIDS risk factors, regardless of the time of day. Recently, the maturation of spontaneous arousals was compared in term newborns during the day and during the night: during the day, there was a lower total sleep time (TST) and lower sleep efficiency (SE) with less QS and AS compared to during the night [ 27 ]. However, there were more arousals, especially in AS (AAS) during the day than during the night.…”

The objective of this study was to compare the maturation of spontaneous arousals during day and night sleep in preterm and term infants. From the Autonomic Baby Evaluation study, the sleep and arousal characteristics of 12 preterm (35.1 ± 2.1 weeks’ gestational age, GA) and 21 term (39.8 ± 0.8 weeks GA) newborns were compared between diurnal and nocturnal sleep periods at birth (M0) and 6 months (M6) of age. Models were adjusted for time (night/day), maturation (M0/M6), prematurity (yes/no). We found that preterm infants had less active sleep (AS)% than term infants with maturation during both day and night sleep, which may reflect accelerated brain maturation secondary to stress or environmental exposure after birth. Moreover, there was a difference in arousal maturation during day and night sleep in the preterm infants, as shown previously for term infants, which suggests the emergence of a circadian rhythm during the earliest postnatal period. We also showed that compared to term infants, these moderate preterm infants had fewer total arousals and, more specifically, fewer arousals in AS during day and night sleep, exposing them to a higher risk of sudden infant death syndrome.
