Background and objective The prevalence and control of asthma in all ages are seldom known in Jinan, China. This study aims to determine the prevalence, related factors and control of asthma in populations of all ages in Jinan, China. Methods A cross-sectional epidemiological questionnaire survey was performed with all members from approximately 4500 randomly selected families from 60 communities in the urban area and in 40 villages in the rural area. The completed questionnaires were focused on asthma, asthma-like respiratory symptoms and asthma control. Results A total of 13 645 individuals were interviewed in the survey, and the number of effective questionnaires reached 13 419. The asthma prevalence of all ages in Jinan was 1.1%. Atopy, asthma family history, household size and age were independent factors related to asthma. The control of asthma in Jinan was suboptimal in a high proportion of patients and even worse in the rural area. Conclusions The asthma prevalence for all ages in Jinan was relatively low compared with that in western countries; however, local asthma control fell markedly short from the goals of the Global Initiative for Asthma (GINA) criteria for asthma management, which may be attributed to the poor adherence to GINA guidelines, especially the underuse of preventative medication of inhaled corticosteroids. This cross-sectional epidemiological survey, using a standardized questionnaire and random sampling methods and being conducted in both urban and rural areas at the same time, presents the most updated information on asthma prevalence and asthma control in the population of all ages in Jinan, China. © 2012 Asian Pacific Society of Respirology.
