title: Exploring psychosocial correlates of physical activity among children and adolescents with spina bifida.
abstract: BACKGROUND
  To enhance physical activity of children with spina bifida, it is important to investigate the correlates of physical activity to support the development of interventions to promote active lifestyles.
  
  
  OBJECTIVE
  This study aimed to identify psychosocial correlates of physical activity among children and adolescents with spina bifida.
  
  
  METHODS
  A survey was conducted with 31 students (15 boys), aged 10-17 years with spina bifida. A questionnaire was used to collect data of physical activity, demographic and psychosocial variables (attitudes, sports goal orientation and perceptions). Unadjusted and adjusted binary logistic regressions were performed to examine the relationship of psychosocial factors and physical activity participation. Data were collected in 2013.
  
  
  RESULTS
  Only 38.7% reported to participate in both organized and non-organized physical activity. Results showed no relationship between participation in organized and non-organized physical activity and psychosocial correlates. The result of the adjusted regression analysis show that perception of competence (OR = 9.55, 1.06-85.99, p < 0.05) was the only variable positively associated with participation in non-organized physical activity.
  
  
  CONCLUSIONS
  Most of the participants reported that they did not participate in physical activity regularly. Psychosocial variables were not related with physical activity, except perception of competence. Studies with bigger samples are needed, focused on the same and in others factors to identify the predictors of physical activity of young people with spina bifida.
