title: [Relations between aggressive behavior and family factors among preschool children in Shanghai].
abstract: OBJECTIVE
  To describe the prevalence of aggressive behavior among preschool children and its related family factors.
  
  
  METHODS
  1234 preschool children in ten kindergartens were rated on their aggressive behavior by their parents, using Child Behavior Checklist (CBCI), Parent Behavior Inventory (PBI) and a general questionnaire.
  
  
  RESULTS
  The overall prevalence of aggressive behavior among preschool children was 12.9% (95%CI: 11.0 - 15.0) according to the CBCL assessment, with the rate being slight higher (13.7%, 93/680) in boys than in girls (11.9%, 66/554). Data from logistic regression analysis showed that parents' hostile/coercive parenting style (OR = 2.396, 95%CI: 1.636 - 3.510) and inconsistent parenting attitude between parents and grandparents (OR = 1.867, 95%CI: 1.287 - 2.710) would lead to more aggressive behaviors in preschool children. Compared with children without difficulty in falling asleep, those who often (OR = 3.415, 95%CI: 1.901 - 6.135) or sometimes (OR = 2.147, 95%CI: 1.256 - 3.671) had problem falling asleep at night had more aggressive behaviors. On the other hand, factors as: watching TV less than 1 hour each day (OR = 0.252, 95%CI: 0.136 - 0.467), father in older age (OR = 0.703, 95%CI: 0.503 - 0.983) and participating in regular outdoor activities (OR = 0.617, 95%CI: 0.399 - 0.955) were protective factors to the aggressive behaviors of the children.
  
  
  CONCLUSIONS
  The prevalence of aggressive behavior in preschool children was high which called for more attention. Intervention programs targeting the family should consider the influencing factors as ways of parenting, consistent attitude on parenting in the family etc. to reduce the occurrence of aggressive behavior among preschool children.
