Participation in organized sport and disruptive behavior in childhood: A prospective, population-based study.

Child disruptive behavior refers to ongoing patterns of disorganized, uncooperative, and defiant behavior. Sport involvement promotes positive child development. However, few longitudinal studies have tested the association between organized sport participation and the behavioral components of disruptive behavior. First, we aim to examine the link between inattentive, hyperactive, aggressive, and oppositional behavior at age 4 years and trajectories of organized sport participation from ages 6 to 10 years. Then, we compare children, according to trajectory membership, on outcome differences on these same behaviors at age 12 years. Data are from the Quebec Longitudinal Study of Child Development (N = 1492). Child behavior was assessed by questionnaires completed by mothers at age 4 years and teachers at age 12 years. Preschool child inattention as perceived by mothers, significantly reduced the odds of middle childhood organized sport participation by 7% (95% CI = 1.00-1.15). Low or inconsistent participation in organized sport was subsequently associated with increased inattention (d = 0.28) by the end of sixth grade. These findings are above and beyond individual and family characteristics and baseline behavior. No other associations were statistically significant. Inattentive children who participated less in organized sport showed a greater likelihood toward increases in attention deficit by the end of sixth grade. To improve engagement from these children, coaches and trainers should use strategies that support positive experiences such as developing a one-to-one alliance with the child, favoring social cooperation through team spirit, and focusing on the performance experience rather than the outcome of winning or losing.

Consistent participation in organized physical activity predicts emotional adjustment in children.

BACKGROUND: The objectives of this study were to derive trajectories of childhood participation in organized physical activity (PA) and to examine how these trajectories are associated with pre-existing and subsequent emotional adjustment. METHODS: Trajectories of mother-reported participation in organized PA were derived from age 6 to 10 for 1492 children from the Québec Longitudinal Study of Child Development birth cohort. Parents and teachers reported on internalizing behavior (emotional distress, anxiety, shyness, social withdrawal) at ages 4 and 12, respectively. RESULTS: Longitudinal latent class analysis identified two typical trajectories of participation in organized PA. The Consistent Participation trajectory (61%) included children with elevated probability of participation at all ages. The Low-Inconsistent Participation trajectory (39%) included children who did not participate or participated only once or twice, generally in late childhood. Pre-existing internalizing behavior at age 4 did not predict trajectory membership. However, children in the Low-Inconsistent Participation trajectory showed higher subsequent emotional distress (B = 0.87, 95% confidence interval [CI] = 0.46-1.28), anxiety (B = 0.61, 95% CI = 0.18-1.04), shyness (B = 0.92, 95% CI = 0.39-1.44), and social withdrawal (B = 0.86, 95% CI = 0.37-1.34) at age 12 than those in the Consistent Participation trajectory. CONCLUSIONS: Our findings suggest that early and sustained involvement in organized PA is beneficial for children's emotional development.
