De rol van geslacht in de relatie tussen slaap en cognitie bij kinderen

In the last 100 years sleep duration of children declined with one hour a night. This is alarming, because it has been established that sleep duration has an influence on cognitive functions of children. To enhance the optimal development of boys and girls, we examined whether gender moderates the association between sleep duration and cognitive functioning. In this study 501 children, 229 boys and 272 girls, with an average age of 10.5 years participated. Parents kept a sleep diary for their child. The child completed various computer tasks which measure cognitive functions attention, inhibition and working memory. These were respectively the PVT, the PVT Go/No-Go and Digit Span. At home, the child did four Word pair tasks to measure declarative memory. Correlation analyses showed that shorter sleep duration was significantly associated with more attention (r = .18), less inhibition (r = .11) and better working memory (r = -.19), but not with declarative memory.

Gender did not moderate the relations sleep duration and cognitive functions. However, girls performed significantly better than boys on the cognitive functions inhibition and working memory. Parents, teachers, social workers and children should know that short sleep duration as well as long sleep duration is associated with declined cognitive functioning, so the development of children can be advanced. It is also important to examine the best sleep duration for children of different ages, so they can use their best attention, working memory and inhibition and they can develop optimally.Show less
