ObjectiveTo investigate the medical knowledge and treatment compliance of parents of asthma children in Gaoming District, Foshan City. MethodOne hundred consecutive parents of asthma children who sought pediatric service in Gaoming People's Hospital from January to December in 2012 were surveyed by the use of Knowledge-Belief-Behavior Questionnaire developed by Capital Research Center of Pediatrics. ResultsNinety-five of the one hundred questionnaires provided useful data for analysis. Among these parents, 63.18% understood the nature of asthma being hyperactive inflammatory disease of the airways; 78.91% believed it to be controllable by regular treatment; only 21.05% of asthma children under parental guidance received inhaled corticosteroids on a regular basis; 14.74% considered their children fit for physical exercises when stabilized; 22.10% chose inhaled β2 agonists as "relievers" during attacks; 61.05% were concerned about the side effects on growth of inhaled corticosteroids and 48.42% discontinued its use against physician's instruction; 82.11% of asthma children had not been evaluated by Asthma Control Questionnaire. ConclusionsParents of asthma children in Gaoming District, Foshan City have weak links in the understanding of this condition. Though most believe it to be controllable under regular treatment, the overall compliance is unsatisfactory. Therefore, knowledge of asthma should be propagated at various public fronts in order to better improve the treatment compliance and consequently the disease control, of asthma children.
