The role of Physical activity in Behavioural inhibition and Sleep difficulties: Age and gender differences

Abstract Aim: Sleep difficulties are a common problem among young children. Reduction in sleep affects cognitive processes and therefore has consequences for development and functioning in daily life. Behavioural inhibition, which includes avoidant behaviour, is expected to be an important predictor for Sleep difficulties. Previous research stated that Physical activity on the other hand could reduce Sleep difficulties. Therefore this study investigated the role of Physical activity in the relation between Behavioural inhibition and Sleep difficulties in boys and girls aged five and ten. Methods: This study used data from the GGD Nederland. Questionnaires from the “Jij en Je Gezondheid vragenlijst” are used to measure the three variables. Parents of a total of 12118 five year olds and 11256 ten year olds completed the questionnaire. The data was analysed by a mediation analyses and a moderated mediation analysis in PROCESS SPSS. Results: The results show significant correlations...Show moreAbstract Aim: Sleep difficulties are a common problem among young children.

Parents of a total of 12118 five year olds and 11256 ten year olds completed the questionnaire. The data was analysed by a mediation analyses and a moderated mediation analysis in PROCESS SPSS. Results: The results show significant correlations between all the three mutual variables. This means that there is some dependence between the variables. In addition, significant relations were found, however the effect sizes of the mediation model were too small (d=.11) to be of actual meaning. Conclusion: The current study does not find enough evidence for Physical activity to be a mediator in the relationship between Behavioural inhibition and Sleep difficulties. Future research should use different psychometric measures and focus more on exercising rather than Physical activity in general.Show less
