Risk factors associated with hospital emergency visits among asthmatic schoolboys in Saudi Arabia.

This cross-sectional study was carried out to determine the prevalence of a positive history of hospital emergency visits (HHEV) among asthmatic Saudi schoolboys. Data were collected using self-administered questionnaires to parents. The prevalence rate for positive HHEV among questionnaire-diagnosed asthmatic boys (QDAs) was 65.0%. Factors associated with positive HHEV among QDAs were determined. Modifying the preventable factors associated with the total number of hospital emergency room visits is expected to decrease the severity and the disability of this disease.
