Use of Antiasthmatic Drugs and the Risk of Type 1 Diabetes in Children: A Nationwide Case-Cohort Study
Asthma has been reported to be associated with an increased risk of type 1 diabetes mellitus in childhood, but the reasons are unclear. We examined whether the use of antiasthmatic drugs was associated with the development of type 1 diabetes in childhood in a nationwide, register-based case-cohort study. We identified all children who were born January 1, 1995, through December 31, 2008, in Finland and diagnosed with type 1 diabetes by 2010 (n = 3,342). A 10% random sample from each birth-year cohort was selected as a reference cohort (n = 80,909). Information on all dispensed antiasthmatic drugs (Anatomical Therapeutic Chemical classification system code R03) during 1995-2009 was obtained, and associations between the use of antiasthmatic drugs and the development of type 1 diabetes were investigated using time-dependent and time-sequential Cox regression models. Dispensed inhaled corticosteroids and inhaled β-agonists were associated with an increased risk of type 1 diabetes after adjusting for other antiasthmatic drugs, asthma, sex, and birth decade (hazard ratio = 1.29, 95% confidence interval: 1.09, 1.52, and hazard ratio = 1.22, 95% confidence interval: 1.07, 1.41, respectively). These findings suggest that children using inhaled corticosteroids or inhaled β-agonists might be at increased risk of type 1 diabetes.
