“…In contrast, other cross-sectional studies found no differences in sleep variability in overweight or obese groups versus normal groups. 12,24 Similarly, a longitudinal study in Danish children showed no association between baseline sleep variability based on self-reports and gain in adiposity 1 year later. 14…”

“…It is of note that some recent studies have focused on less typical sleep aspects such as daily variations (Spruyt et al, 2016) and chronotype (Doi et al, 2015). Others have explored sleep hygiene, such as bedtime routine (Mindell et al, 2015), showing the importance of educating parents on the matter.…”

This is the first systematic review of the literature on sleep and its relation to cognition and behaviour in preschool-aged children. In comparison with the literature focused on school-aged children, knowledge involving preschoolers is rather sparse. A total of 26 studies was included in this review, which revealed a high degree of heterogeneity regarding the type and means of measuring sleep variables and behavioural and cognitive variables, as well as the statistical methods employed. Amongst the 13 articles with the largest sample sizes (top 50% of the included studies, 12 different populations), 12 found that a higher quantity or quality of sleep was associated with better behavioural and/or cognitive outcomes. Results point to an association between sleep, behaviour and cognition as early as preschool years, but the strengths of associations reported in the articles were relatively small. Studies with a smaller sample size were less concordant. It is consistent with our findings that the strengths of association are small, and thus require large sample sizes to ensure statistical detection power. Different aspects of sleep were not associated with all cognitive or behavioural features in the same way, which underscores the need for specific measures rather than general ones such as 'sleep problems' or 'behaviour problems' to be able to decipher the relationships. There is also a need for large longitudinal studies using objective measures and accounting for confounding factors. The child's genotype has recently been shown to have a moderating role in the association between sleep and behaviour, and should be further explored.

Objective As the COVID-19 pandemic brings widespread changes in families, the sociology of sleep becomes noticeable. Yet, the socio-contextual determinants of a biopsychosocial phenomenon as sleep are poorly investigated. We examine changes concomitantly occurring in the child's sleep per familial and community stressors. Methods During the pre-COVID-19 outbreak period, in 24 minority children (5.4±1.7 years old, 54.2% girls), sleep was objectively measured 24-hours for two consecutive weeks, and this was repeated three times over the study period of three months. The caregiver filled out questionnaires surveying sociodemographic, community and family aspects. Results Children went to bed at 22:26 and woke up at 07:04, with each a variability of about 50 minutes. Money and time were revealed as related key stressors to sleep. Five dimensions best fitted their association. In general, concurrent changes within the individual child indicate that mean sleep variables seem to relate to predominantly features of the stressors (explained variance of 34.7% to 56.7%), while variability of sleep tends to associate to situational aspects of the stressors (explained variance of 30.4% to 61.8%). Associations were best explained in terms of the 24-hour dimension, particularly exposing sleep variability. Conclusion Individual variabilities in a child's sleep are associated with familial resources, such as caregiver's time to self, money and basic needs. Time spent in bed, a modifiable factor by society and shaper of sleep quantity and quality, plays a key role in stressor-sleep associations. Insights from biopsychosocial perspectives may be valuable for understanding COVID-19 sleep studies, and the development of (post-)COVID-19 sleep recommendations.
