The associations between children’s cognitive processes and objectively measured physical activity, sedentary time and self-reported screen time.

Abbreviations: B, estimate; SE, standard error; CI, confidence interval; p, P-value; MVPA, moderate to vigorous physical activity.
aRTI measures children’s reaction time and speed of response to a visual target in milliseconds, where faster time indicates better performance.
bMVPA measured with the ActiGraph accelerometer using a cut-off value of 2,296 counts per minute and expressed as min/day.
cSedentary time measured by the ActiGraph accelerometer using a cut-off value of 100 counts per minute and expressed as percentage of daily monitoring time (%/day).
dRVP measures the sustained attention. The score of this task is RVP A’, where range is 0.00 to 1.00; bad to good.
eSSP measures length of the visuospatial working memory span. The score of this task is the maximum number of items that the child can successfully reproduce.
fSelf-reported viewing of television, playing of computer/video games and use of computer (other than playing) are expresses as h/day.
gP-values for parameter estimates.
Models have been adjusted with gender (female), the highest level of parental education (tertiary level) and child’s need for remedial education.
