Race and socioeconomic status (SES) moderated the link between children's sleep and cognitive functioning. One hundred and sixty-six 8- to 9-year-old African and European American children varying in SES participated. Sleep measures were actigraphy, sleep diaries, and self-report; cognitive measures were from the Woodcock-Johnson III and reaction time tasks. Children had similar performance when sleep was more optimal, but after controlling for SES, African American children had lower…

Concurrent and longitudinal relations between children's sleep and cognitive functioning: the moderating role of parent education.

Children's sleep was related to intellectual ability and academic achievement and build substantially on an emerging literature supportive of the importance of sleep in children.

Children's sleep and cognitive performance: a cross-domain analysis of change over time.

It is demonstrated for the first time that children's sleep trajectories over 3 waves were associated with changes in their cognitive performance over time, and Sleepiness served as a vulnerability factor for poor cognitive outcomes, especially among African American children and girls.

Sleep and Cognitive Functioning in Childhood: Ethnicity, Socioeconomic Status, and Sex as Moderators

Findings indicate that lower sleep efficiency may contribute to lower cognitive functioning especially for AA children and boys, and underscore the importance of individual differences in explicating relations between sleep and children's cognitive performance.

Children's sleep and adjustment over time: the role of socioeconomic context.

Cross-sectionally and longitudinally, sleep problems were associated with worse adjustment outcomes; African American children or those from lower socioeconomic status homes were at particular risk.

Economic adversity and children's sleep problems: multiple indicators and moderation of effects.

Objectively and subjectively assessed sleep parameters were related to different SES indicators, and overall worse sleep was evident for children from lower SES homes, and Ethnicity was a significant moderator of effects in the link between some S ES indicators and children's sleep.

Examining sleep as a protective mechanism for executive functioning in children from low-income homes

ABSTRACT For young children, sleep is essential for healthy development. Inadequate sleep can affect emotional, behavioural, cognitive, and health outcomes. Low family income and resources can put

Mothers’ sleep deficits and cognitive performance: Moderation by stress and age

In a sample of mothers of toddlers, poorer cognitive performance was predicted by greater activity during the sleep period, shorter sleep duration, and lower night-to-night consistency in sleep; it was not associated with higher levels of stress.

Child Sleep and Socioeconomic Context in the Development of Cognitive Abilities in Early Childhood.

Results revealed a between-subject effect in which the children who had more delayed sleep schedules on average also showed poorer cognitive abilities on average but did not support a within-subjects effect.

Sleep quality and cognitive performance in 8-year-old children.




School performance, race, and other correlates of sleep-disordered breathing in children.

Sleep, neurobehavioral functioning, and behavior problems in school-age children.

Children with fragmented sleep were characterized by lower performance on NBF measures, particularly those associated with more complex tasks such as a continuous performance test and a symbol-digit substitution test, which raised important questions about the origins of these associations and their developmental and clinical significance.

Sleep and adjustment in preschool children: sleep diary reports by mothers relate to behavior reports by teachers.

A structural equation model showed that disrupted child sleep patterns predicted less optimal adjustment in preschool, even after considering the roles of family stress and family management practices.

Socioeconomic Status and Health: The Role of Sleep

Sleep quality may play a mediating role in translating SES into mental and physical well-being, and income seems to mediate the effect of education on sleep and, in turn, health.

The effects of sleep restriction and extension on school-age children: what a difference an hour makes.

Sleep restriction led to improved sleep quality and to reduced reported alertness and the sleep manipulation led to significant differential effects on NBF measures.

Sleep patterns and sleep disruptions in school-age children.

The findings reflected significant age differences, indicating that older children have more delayed sleep onset times and increased reported daytime sleepiness, and girls were found to spend more time in sleep and to have an increased percentage of motionless sleep.

Cognitive function following acute sleep restriction in children ages 10-14.

Higher cognitive functions in children, such as verbal creativity and abstract thinking, are impaired after a single night of restricted sleep, even when routine performance is relatively maintained.

Neurobehavioral correlates of sleep‐disordered breathing in children

Using a novel algorithm to assess sleep pressure, it was found that children with SDB were significantly sleepier than controls and total arousal index was negatively correlated with neurocognitive abilities, suggesting a role for sleep fragmentation in pediatric SDB‐induced cognitive dysfunction.

Sleep schedules and daytime functioning in adolescents.

Most of the adolescents surveyed do not get enough sleep, and their sleep loss interferes with daytime functioning.

Racial differences in reported napping and nocturnal sleep in 2- to 8-year-old children.

There are remarkable racial differences in reported napping and nighttime sleep patterns beginning as early as age 3 and extending to at least 8 years of age, independent of commonly investigated demographic factors.
