Abstract Objective To investigate the prevalence rate of childhood asthma in 2010 in urban Baotou, China, as well as the characteristics of attacks and the status of diagnosis and treatment of childhood asthma. Methods More than 10 000 children (0-14 years) were selected from 3 secondary schools, 3 primary schools, 6 kindergartens, and 4 community vaccination sites in urban Baotou by cluster random sampling between September 2009 and August 2010. A standardized preliminary questionnaire was used for screening out suspected cases, which were then confirmed or excluded by a clinician; the confirmed cases underwent further questionnaire survey. Double entry and validation was adopted for all data using Epi-Info software, and analysis was performed using SPSS 13.0. Results A total of 11 323 children were surveyed. Asthma was diagnosed in 127 cases (including 121 children with typical asthma and 6 children with cough variant asthma), with a prevalence rate of 1.12%. The prevalence rate of asthma in male children was significantly higher than that in female children (1.51% vs 0.72%; PPPPPConclusions The prevalence rate of childhood asthma in urban Baotou shows an increasing trend. Inhaled corticosteroids have been widely used.
