Background: Diabetes is the most prevalent chronic metabolic disorder in children and adolescents, and incidence rates for both type-1 and type-2 diabetes are increasing worldwide. In recent years, the number of patients with type 1 diabetes is increasing mainly due to children under 5-years-old.

Objective: To study the epidemiological indicators of T1DM among children of the Republic of Armenia (RA) from 2007 to 2016. Methods: Retrospective analysis of the Republican Children’s Endocrinology Center database using conventional statistical methods.

Results: During the period 2007–2010 in Armenia there was a relatively stable incidence of diabetes in children 0–18 years: 7.1 in 2007, 6.45 in 2008, 6.3 in 2009 and 6.8 in 2010 (per 100 000 child population), while during 2010–2016 period increased incidence is seen (6.7 in 2011, 9.4 in 2012, 8.7 in 2013, 9.99 in 2014, 10.69 in 2015). The study of age-specific morbidity in children with T1DM in RA showed that the maximum incidence in different years was at the age of 5–9 or 10–14 years. According to the Republican Children’s Endocrinology Center data rejuvenation of type 1 diabetes can be traced. Mean age of patients in 2007 was 11 years. In 2014 mean age was 8.9 and 9.8 in 2016. The incidence rate in children of younger age group (0–4 years) increased from 2.24 in 2007 to 5.05 in 2010, 7.14 in 2014 and 5.8 in 2016 (per 100 000 child population).

Conclusions: In RA an increased incidence of type 1 diabetes among children and adolescents is seen. The highest incidence occurs in the age groups 5–9 and 10–14 years. Further studies are needed to look into the cause of these changes.
