IN A STUDY of 2006 school children living in two urban areas of the Kingdom of Saudi Arabia, we used a questionnaire to collect details of age, sex, areas of residence, occupation, education, social class, parental history of asthma and information relating to parental smoking habit. The relative importance of these factors on the likelihood of children having bronchial asthma was assessed using a linear modelling analysis. The extent to which these factors affected the severity of bronchial asthma was also examined. A number of statistically significant associations between bronchial asthma and 'breathlessness' (P <0.0087), 'Father smoker' (P <0.0001), 'usually cough' (P <0.0001), 'pets' (P <0.0067) and 'Family history of allergy' (P <0.007), were found.
