“…Also, we performed longitudinal analyses of the associations between TV exposure in early childhood and later verbal IQ at age 5–6 years, a method ensuring that a potential cause precedes its potential effect, unlike cross-sectional analyses that have been the most frequent in the literature so far. Finally, we performed a sensitivity analysis with factors identified as potential mediators between TV exposure and language development: the results remained unchanged when including sleep characteristics, which agrees with recent results identifying a main action of sleep quality and quantity on executive functions rather than language development 42 .…”

Studies in children have reported associations of screen time and background TV on language skills as measured by their parents. However, few large, longitudinal studies have examined language skills assessed by trained psychologists, which is less prone to social desirability. We assessed screen time and exposure to TV during family meals at ages 2, 3 and 5–6 years in 1562 children from the French EDEN cohort. Language skills were evaluated by parents at 2 years (Communicative Development Inventory, CDI) and by trained psychologists at 3 (NEPSY and ELOLA batteries) and 5–6 years (verbal IQ). Cross-sectional and longitudinal associations were assessed by linear regression adjusted for important confounders. Overall, daily screen time was not associated with language scores, except in cross-sectional at age 2 years, where higher CDI scores were observed for intermediate screen time. Exposure to TV during family meals was consistently associated with lower language scores: TV always on (vs never) at age 2 years was associated with lower verbal IQ (− 3.2 [95% IC: − 6.0, − 0.3] points), independent of daily screen time and baseline language score. In conclusion, public health policies should better account for the context of screen watching, not only its amount.

“…We report for the first time an association between night sleep fragmentation, objectively measured by polysomnography in the early months of life and lower verbal performance scores at 36 months of age. These results are in agreement with other studies that used objective sleep evaluation such as actigraphy [6,7], but also with a previous study that we reported which used parental night awakening reports at 6 months [11]. Other authors reported that fragmented sleep has been associated with memory difficulties and poorer academic achievement in older children [18] probably due to lower sleep efficiency tracking throughout childhood [19].…”

“…showed that snore-related arousals in the absence of apneas or hypopneas, are negatively correlated with mental scores [34]. In the previous study that we reported, frequent snoring signaled by parents at 18 months was associated with lower PIQ and Block design scores at 3 years of age [11].…”

“…Contrary to the latter studies, Sheridan et al reported that the relationship observed between sleep disturbance at 12 and 18 months and lower intelligence quotient (IQ) scores at 5 years of age, was no longer statistically significant after adjusting on psychosocial adversity [10]. Recently, we evaluated the relationship between sleep data collected via questionnaires at birth, 6,12,18, and 24 months and the Weschler Preschool and Primary Scale Intelligence-III (WPPSI-III) scores at 3 years of age in 194 children from the French birth-cohort AuBE [11]. We found that night wakings at 6 months of age and frequent snoring at 18 months of age were negatively associated with performance IQ (PIQ) at 3 years of age.…”

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.

“…However, day sleep in early childhood is less investigated in relation to cognitive performance. Plancoulaine et al found that day/night sleep ratio was positively associated with Full Scale IQ scores [ 44 ] Knowland et al also showed that more night sleep relative to day sleep, was predictive of better receptive vocabulary [ 45 ]. Napping has been associated with shorter night sleep and poorer sleep quality [ 41 ] and increased napping has been previously reported to negatively affect language comprehension [ 46 ].…”

Study Objectives Examine how different trajectories of reported sleep duration associate with early childhood cognition. Methods Caregiver-reported sleep duration data (n=330) were collected using the Brief Infant Sleep Questionnaire at 3, 6, 9, 12, 18 and 24 months and Children’s Sleep Habits Questionnaire at 54 months. Multiple group-based day-, night- and/or total sleep trajectories were derived – each differing in duration and variability. Bayley Scales of Infant and Toddler Development-III (Bayley-III) and the Kaufman Brief Intelligence Test- 2 (KBIT-2) were used to assess cognition at 24 and 54 months respectively. Results Compared to short variable night sleep trajectory, long consistent night sleep trajectory was associated with higher scores on Bayley-III (cognition and language), while moderate/long consistent night sleep trajectories were associated with higher KBIT-2 (verbal and composite) scores. Children with a long consistent total sleep trajectory had higher Bayley-III (cognition and expressive language) and KBIT-2 (verbal and composite) scores compared to children with a short variable total sleep trajectory. Moderate consistent total sleep trajectory was associated with higher Bayley-III language and KBIT-2 verbal scores relative to the short variable total trajectory. Children with a long variable day sleep had lower Bayley-III (cognition and fine motor) and KBIT-2 (verbal and composite) scores compared to children with a short consistent day sleep trajectory. Conclusions Longer and more consistent night- and total sleep trajectories, and a short day sleep trajectory in early childhood were associated with better cognition at 2 and 4.5 years.

Abstract: We showed that early features including infant sleep characteristics influence IQ scores at 36 months old. Some of these may be accessible to prevention.
