In recent times, the incidence of @entity56 , particularly @entity565 , has been increasing worldwide. However, there appears to be no published data on the prevalence of @entity56 among school @entity1 (3 to 16 years of age) in Karachi, Pakistan, with only limited data available among few age groups under one ISAAC study. The objective of this project was to investigate the prevalence of @entity56 among school @entity1 (3 to 16 years of age) in the city of Karachi. The questionnaire that was used for data collection had previously been used for a similar study in neighboring Saudi Arabia and the U.A.E. In 2007, a total of 3,000 surveys were distributed in various schools of Karachi, of which 2,325 completed surveys were obtained. SPSS was used to perform statistical analysis on the collected data. Survey results showed that the frequency of diagnosed (previously seen by physicians) cases of @entity565 stood at 15.8%, while the frequency of @entity2023 was found to be 28.50% among these @entity1 . Other parameters that were analyzed included dry cough (20.1%), wheezing (11.7%), @entity1353 (15.40%), and @entity484 (21.8%). Furthermore, smoking by family members was found to be associated with @entity565 (p value less than 0.05), @entity2023 (p value less than 0.05), @entity1353 (p value less than 0.05), dry cough (p value 0.002), and wheezing (p value less than 0.05). This study reveals that there is a significant number of school @entity1 in the metropolitan city of Karachi who have @entity56 . It also sheds light on the fact that exposure to indoor environmental factors as well as family atopy can play a key role in increasing the chances of an individual to experience @entity565 and @entity566 .
