Associations between sedentary behavior and motor coordination in children.

چکیده
OBJECTIVES This study was conducted to evaluate the relationship between objectively measured sedentary behavior (SB) and motor coordination (MC) in Portuguese children, accounting for physical activity (PA), accelerometer wear time, waist-to-height ratio, and mother's education level. METHODS A cross-sectional school-based study was conducted on 213 children (110 girls and 103 boys) aged 9-10 in the north of Portugal during the spring of 2010. Accelerometers were used to obtain detailed objective information about daily PA and SB over five consecutive days. MC was measured with a body coordination test (Körperkoordination Test für Kinder). Waist and height were measured by standardized protocols and the waist-to-height ratio (WHtR) was calculated. A questionnaire was used to assess mothers' educational levels. Receiver-operating characteristic (ROC) and logistic regressions were used. RESULTS ROC analysis showed that sedentary time significantly discriminated between children with low MC and high MC, with a best trade off between sensitivity and specificity being achieved at ≥77.29% and ≥76.48% for girls and boys, respectively (P < 0.05 for both). In both genders, the low sedentary group had significantly higher odds of having good MC than the higher sedentary group, independent of PA, accelerometer wear time, WHtR, and mother's education level (P < 0.05 for both). CONCLUSIONS Our findings suggested that PA levels per se may not overcome the deleterious influence of high levels of SB on MC. Our data stress the importance of discouraging SB among children to improve MC.

Prospective associations between measures of gross and fine motor coordination in infants and objectively measured physical activity and sedentary behavior in childhood
One important determinant of childhood physical activity and sedentary behavior may be that of motor development in infancy. The present analyses aimed to investigate whether gross and fine motor delays in infants were associated with objective and self-reported activity in childhood. Data were from the UK Millennium Cohort Study, a prospective cohort study, involving UK children born on or aro...

Introduction: Developmental Coordination Disorder (DCD) is a serious childhood disorder that causes social, emotional, cognitive, and motor difficulties for children. Accordingly, the current study aimed to examine the effect of perceptual-motor training on the improvement of neurocognitive functions in children with DCD.

BACKGROUND Higher levels of gross motor coordination are positively associated with physical activity in childhood, but little is known about how they relate to sedentary behaviour. The aim of this study was to investigate the longitudinal association between gross motor coordination at childhood and sedentary behaviour in adolescence and adulthood. METHODS Data were from the 1970 British Coh...
