Background Although achieving and maintaining control of asthma is considered to be the goal of asthma treatment, determinants of asthma control are not fully understood. Our aim was to assess factors associated with asthma control among paediatric patients in the general population. Methods In June 2012, a Web‐based survey was conducted to identify Japanese children aged 6 to 11 yr who currently have asthma and evaluate control of their disease using the Childhood Asthma Control Test (C‐ ACT ). Associations were evaluated among uncontrolled asthma (C‐ ACT score <20) between environmental factors, demographics and comorbid allergic diseases. Results Among the 3066 children with current asthma, 447 (14.6%) had uncontrolled asthma. Multivariable analysis identified factors such as low birthweight (adjusted OR 1.65, 95% CI 1.25–2.18), obesity (adjusted OR 1.44, 95% CI 1.05–1.99) and pet ownership before birth (adjusted OR 1.68, 95% CI 1.24–2.29) to be associated with uncontrolled disease. Comorbid allergic diseases, especially rhinitis were a significant risk of uncontrolled asthma (adjusted OR for severe rhinitis: 3.88, 95% CI 2.50–6.00). The severity of rhinitis symptoms was inversely correlated with the C‐ ACT score (p < 0.001). Conclusions A population‐based Web survey showed an association between several factors and the control of paediatric asthma. The assessment of these factors may help identify the children at risk with uncontrolled asthma.
