The diagnosis of diabetic ketoacidosis was made with the criteria below, Children presenting with polysymptoms, weight loss, vomiting, dehydration, and also the indirect signs or effects of acidosis on respiratory and central nervous systems like Kussmaul breathing, lethargy or coma and biochemically random blood sugar level >11 ml/L, glucosuria and urine ketone >+1 and diagnosed with type 1 diabetes for the first time. Descriptive, Mann–Whitney U and logistic regression analysis were carried out to describe and identify the associated factors with diabetic ketoacidosis.Results: More than three-quarters, 258/328 (78.7%) of the newly diagnosed type 1 diabetes patients, presented with diabetic ketoacidosis at initial diagnosis. Median age of diabetic ketoacidosis patients was 11 years. The patients with diabetic ketoacidosis were younger than nondiabetic ketoacidosis patients (11 vs 13 years, P=0.002). The mortality rate of diabetic ketoacidosis was 4.3%. Young age, presence of precipitating factors and symptoms of DKA/diabetes were found to be highly associated with diabetic ketoacidosis at initial diagnosis.Conclusions: The prevalence of diabetic ketoacidosis was alarmingly high. Young age group patients, precipitating factors and the presence of symptoms of diabetes/DKA like excessive drinking, vomiting and fatigue were highly associated with diabetic ketoacidosis.Keywords: prevalence, type 1diabetes, ketoacidosis, children, Tigray
