OBJECTIVES: Although @entity565 , @entity2023 and @entity484 are among the most common @entity102 in @entity1 worldwide, there is very limited information about the burden of these conditions in Oman. The aim of this study was to determine the prevalence and severity of symptoms of @entity565 , @entity2023 and @entity484 in Omani schoolchildren using the International Study of @entity566 in Childhood (ISAAC) Phase I questionnaire. METHODS: An Arabic version of the ISAAC Phase I questionnaire was completed by parents of 3893 @entity1 aged 6-7 years and self-completed by 3174 @entity1 aged 13-14 years, randomly selected from a nationwide sample of public schools. RESULTS: The prevalence rates of reported diagnoses of @entity565 , @entity2023 and @entity484 were higher in older @entity1 (20.7%, 10.5% and 14.4% compared with 10.5%, 7.4% and 7.5%, respectively, in young @entity1 ). In young @entity1 , 277 were current wheezers and of these 40.8% had sleep-disturbing wheeze at least once a week and 45.1% had speech-limiting wheeze during the past year. Similarly, 283 older @entity1 were current wheezers, and of these 30.0% had sleep-disturbing wheeze at least once a week and 37.5% had speech-limiting wheeze during the past year. Exercise-induced wheeze was higher in older @entity1 (19.2% vs 6.9%; P < 0.001). @entity2023 and @entity484 were also associated with significant @entity25 and limitation of activity in both age groups. CONCLUSION: @entity56 in Omani schoolchildren are common and associated with significant morbidity. Further research is required to identify the local risk factors for @entity566 to allow better understanding and management of these conditions.

A relatively high prevalence and severity of @entity565 , XXXX and atopic eczema in schoolchildren in the Sultanate of Oman.
