title: Self-perception of physical competences in preadolescent overweight Chinese children.
abstract: OBJECTIVE
  To compare self-perceptions of physical competences in overweight and in normal weight preadolescent Chinese children.
  
  
  METHODS
  Cross-sectional study.
  
  
  METHODS
  Three primary schools and a university hospital in Hong Kong.
  
  
  METHODS
  A total of 634 children, comprising 558 (462 normal weight, 96 overweight) aged 8-12 y randomly sampled from three primary schools, and 76 similar age overweight children recruited from the community for a diet and exercise intervention programme.
  
  
  METHODS
  Height, weight and percentage body fat were measured. Self-perceptions of physical competences were determined by Physical Self-Descriptive Questionnaire (PSDQ). Corresponding actual physical competences were measured by physical fitness tests.
  
  
  RESULTS
  Overweight children perceived themselves to have significantly more body fat than normal weight children, with poorer appearance, sports competence, endurance, coordination, flexibility, overall physical self-concept and self-esteem, but to be no less healthy, no less physically active and no less strong. Overweight children performed less well than normal weight children in measures of endurance, coordination and flexibility but better in strength. Poor self-perception of physical competences appeared only partly related to deficiencies in actual physical competences.
  
  
  CONCLUSIONS
  Overweight children have poorer self-perception of their physical competences but do not perceive themselves to be less strong, healthy or physically active than normal weight children. Exercise programmes for overweight children could be more effective if designed with the knowledge of these self-perceptions.
