Description
Sleep is an extremely important component of living a healthy life than can impact development and behavior starting in childhood. We expanded on past research regarding this topic to determine the role of childhood sleep and the onset of problem behaviors (externalizing and internalizing behaviors) among a sample of school-aged children. We predicted that lower sleep duration, decreased sleep efficiency, and prolonged sleep latency along with negative sleep habits would be associated with problem behaviors. Our sample was made up of 381 school-aged children (M = 8.49 years old, 49.6% female, 56% Caucasian) who were recruited through the Arizona Twin Study when the children were 12 months old. Mixed-model regressions included sex, socioeconomic status, and zygosity as covariates. Correlations and mixed-model regressions showed a significant relationship between negative sleep habits and problem behaviors (both externalizing and internalizing). Our results revealed that those who experience higher amounts of parent-reported negative sleep habits also demonstrate externalizing behaviors (aggression) and internalizing behaviors (anxiety). The findings in the current study are consistent with past research on this topic and suggest that poor sleep impacts daytime functioning and behavior.

Description
Academic success in childhood is crucial for later academic, occupational, and life success (Heckman, 2006; Kuncel, Hezlett, & Ones, 2004; Spengler, Brunner, Damian, Lüdtke, Martin, & Roberts, 2015). Recent research suggests sleep is important for academic success but lacks objective measures of sleep (Buckhalt, El-Sheikh, Keller, & Kelly, 2009; Curcio, Ferrara, & De Gennaro, 2006; Dewald, Meijer, Oort, Kerkhof, & Bögels, 2010; Philbrook, Hinnant, Elmore-Staton, Buckhalt, & El-Sheikh, 2017). The purpose of this study was to examine the relations between sleep and academic success among children through objective measures of sleep in order to expand on the literature. Our sample consisted of 381 twins (50.4% male; 56% Caucasian; 36.5% same sex dizygotic) participating in an 8-year assessment from a longitudinal twin study. Actigraphy was used to assess sleep while various measures were used to assess academic success. A series of mixed model regressions were used to test the main predictions, with family entered as a random effect. Sex, age, Hispanic, SES, and zygosity were controlled for. Significant negative relations were revealed between sleep latency and reading and sleep latency and school liking. Additionally, SES was the most consistent significant positive predictor of our measures of academic success. These results suggest sleep and effects of SES should be considered when developing ways to help children’s school performance.

Description
The present study tested 1) whether children’s bedtimes, wake times, and sleep
durations change as they transition into kindergarten (TtoK), 2) if changes to children’s
sleep schedules were contingent on their pre-kindergarten (T1) napping status and if T1
bedtimes were related to fall (T2) and spring (T3) bedtimes and durations, and 3) whether
T1 sleep, changes to sleep from T1 to T2, and concurrent sleep quality were related to
academic achievement and participation in 51 kindergarteners. It was hypothesized that
1) wake times would be earlier and sleep duration would be shorter during kindergarten
(T2 and T3) than at T1, 2) children who napped at T1 would go to bed later and have
shorter sleep duration than their non-napping peers and T1 bedtimes would be positively
associated with T2 and T3 bedtimes and negatively associated with T2 and T3 durations,
and 3) more optimal sleep (e.g., consolidated, consistent, and high quality) would be
positively related to academic achievement and participation. Parents reported on
children’s bedtimes, wake times, and nap lengths during T1, T2, and T3. During T3
children wore actigraphs for five consecutive school nights and completed the Woodcock
Johnson tests of achievement (WJ-III). Teachers also reported on children’s participation
in the classroom during T3. Results demonstrated that bedtimes and wake times were
earlier at T2 and T3 than T1. Duration was shorter at T2 and T3 than T1. Additionally,
napping was unrelated to bedtimes and durations, but T1 bedtime was positively related
to T2 and T3 bedtimes and negatively related to T2 and T3 durations. Finally, T1 nap
length, change in bedtimes, and Actigraphy duration were negatively related to
participation. Actigraphy onset variability was positively related to participation.
