PREVALENCE OF ASTHMA, RELATED SYMPTOMS AND RISK FACTORS IN CHILDREN YOUNGER THAN 5 YEARS

طPersistent cough unrelated to respiratory infections was strongly associated with the positive history of atopy in the children or maternal age at the child birth less than 20 yr or more than 30 yr. Furthermore a physician-diagnosed asthma was significantly associated with positive history of atopy in child. The results suggest a relatively high prevalence of history of wheezing or current and exercise-induced wheezing, but underdiagnosis of asthma among studied children needs more studies to be confirmed.
