title: [Can sports and physical activity promote young peoples' psychosocial health?].
abstract: BACKGROUND
  Sport and physical activity is generally believed to be beneficial to young people's psychosocial health, but the scientific evidence seems equivocal. This article gives a narrative review of recent developments in the literature on psychosocial health effects of physical activity and sport among children and adolescents.
  
  
  METHODS
  Based on a narrative review of a selection of metaanalytical and key studies, results in four areas of psychosocial functioning are presented.
  
  
  RESULTS
  Findings support an association between involvement in physical activity and sport and well-being. Physical activity is associated with lower levels of mental health problems, and seems to promote self-esteem. Physical activity as a treatment of mental health problems for this age group is underexplored and no firm conclusions can be made. The evidence with respect to effects on cognitive and academic functioning is weak. Further, the evidence that juvenile delinquency and antisocial development could be counteracted is equivocal.
  
  
  CONCLUSIONS
  There is a paucity of studies that can confirm any causal effects. Future research would benefit particularly from studying the role of sports and physical activity mode as well as the psychological and social context in which it may produce beneficial psychosocial outcomes.
