title: Prevalence of childhood asthma and control in children assessed in a pilot school-based intervention programme in Singapore.
abstract: OBJECTIVE
  Because of a high childhood asthma burden in Singapore, assessment of disease control status is essential for formulating school-based strategy of childhood asthma control. The aim of the present study is to assess childhood asthma prevalence and control in Singapore and the socio-demographic and help-seeking correlates.
  
  
  METHODS
  School-based survey using parental self-administered questionnaire, conducted from February to April 2004. Four mixed-gender primary schools selected from geographically distinct zones of Singapore. All primary one (modal age - 6.5 years) and six (modal age - 11.9 years) students from selected schools were invited to participate. Questionnaire respondents were the students' parents or guardians. The response rate was 75.2% (2123/2825).
  
  
  RESULTS
  Prevalence of current asthma was 8.9% (190/2123). Among them, 26.3% (46/175) were assessed to have inadequate control. Asthma was more prevalent, and less adequately controlled in children from lower socio-economic backgrounds (lower-end housing type). Children with poorly controlled asthma were more likely to be treated by emergency room physicians and hospital specialists, and to be on preventer medications.
  
  
  CONCLUSIONS
  In Singapore, poor asthma control is found in a sizeable proportion of school children with asthma, is identifiable for high-risk groups of children from lower socio-economic backgrounds and having asthma-related attendance at the emergency rooms.
