OBJECTIVE: We studied the prevalence of diabetic ketoacidosis (DKA) at diagnosis of type 1 diabetes in children in Finland. RESEARCH DESIGN AND METHODS: From 2002 to 2005, data on virtually all children <15 years of age diagnosed with type 1 diabetes (n = 1,656) in Finland were collected. RESULTS: DKA was present in 19.4% of the case subjects, and 4.3% had severe DKA. In children aged 0-4, 5-9, and 10-14 years, DKA was present in 16.5, 14.8, and 26.4%, respectively (P < 0.001). Severe DKA occurred in 3.7, 3.1, and 5.9%, respectively (P = 0.048). DKA was present in 30.1% and severe DKA in 7.8% of children aged <2 years. CONCLUSION: The overall frequency of DKA in children is low in Finland at diagnosis of type 1 diabetes. However, both children <2 years of age and adolescents aged 10-14 years are at increased risk of DKA.
