The burden of asthma among children and adolescents in Saudi Arabia: Anational cross-sectional survey.

Abstract

Asthma disease is one of the most common chronic diseases of childhood. Studies assessing asthma prevalence in Saudi Arabia have been variable and not recently updated. We sought to assess asthma prevalence, severity, and related risk factors among children and adolescents in Saudi Arabia. A national, cross-sectional design was used following the Global Asthma Network phase I design. Atotal of 3817 children aged 6 to 7 years and 4138 adolescents aged 13 to 14 years were recruited from 137 primary and 140 intermediate schools across 20 regions by using a multistage stratified cluster sampling technique. Standardized written questionnaires were answered by the adolescents and by the parents or guardians of the children. The adolescents also answered a video-based questionnaire. Overall, the prevalences of current wheeze were 10.4% and 13.3% and the prevalences of asthma ever were 13.8% and 15.7%, % in children and adolescents, respectively. Of all the children and adolescents, 5.2% and 5.6% had symptoms of severe asthma, respectively. Among those who reported asthma, 86.0% of the children and 74.8% of the adolescents had their asthma confirmed by a doctor, and 53.0% and 32.4%, respectively, were provided with a written plan to control their asthma. The main risk factors associated with current wheeze included antibiotic use in the first year of life, a history of being diagnosed with pneumonia in children, paracetamol use, and having a cat at home during the past 12 months in adolescents. The prevalence of asthma in children and adolescents in Saudi Arabia is within the average international range and is at a plateau phase.
