Background: Reports have identified a rising prevalence of bronchial asthma, with the highest pediatric burden in the 6–11 years old. Aim: This study aimed at determining the epidemiology of asthma among primary school pupils, aged 6–11 years in Kano metropolis. Settings and Design: This study was prospective, descriptive, cross-sectional study carried out among 811 primary school pupils in Kano metropolis from October 2012 to December 2013. Materials and Methods: Information was obtained using pretested questionnaires, and enlisted pupils had their spirometric values recorded. Diagnosis of asthma was based on two or more of the following: recurrent cough, especially nocturnal, recurrent wheeze, recurrent difficulty in breathing with a response to a bronchodilator, and spirometric features of airway obstruction. Statistical Analysis: The data were analyzed with SPSS version 16 using percentages, mean values, standard deviation, Chi-square test, Student's t-test, and multiple logistic regression. P value was significant at ≤0.05. Results: Asthma prevalence was 12.5%. The disease prevalence was comparable across ethnic groups and socioeconomic classes. Neither weight nor height differed significantly between the asthmatic and nonasthmatic pupils. Family history of asthma and physical stigmata of cutaneous atopy were significantly associated with the disease. Conclusions: The prevalence of bronchial asthma among the pupils studied suggests a current local disease burden that is comparable to those of communities in the industrialized countries. There is a need for improved health education and campaigns about the disease not only for Nigerians but also for other countries with the high prevalence.
