Abstract

Objective— To determine, for the first time, the incidence of IDDM among children 0–15 yr of age in Macedonia, the south republic of former Yugoslavia, and to compare these rates with those from neighboring countries.

Research Design and Methods— Children <15 yr of age, with IDDM diagnosed between January 1985 and December 1991, were registered using the criteria established for the WHO Multinational Project for Childhood Diabetes. The primary source of case ascertainment consisted of clinical records from the University Pediatric Clinic in Skopje, the capital of Macedonia. The secondary source consisted of records for insulin supplies from the pharmacy in Skopje and from 15 local hospitals.

Results— During 1985–1991, 112 children <15 yr of age were diagnosed with IDDM in Macedonia. The completeness of case ascertainment was 96.6%. The age-adjusted IDDM incidence rate was very low, only 2.45/100,000 per yr. No significant sex difference in incidence was observed. The highest incidence rate occurred in the 10- to 15-yr age-group. No temporal trends were observed.

Conclusions— The incidence of IDDM in Macedonia is the lowest in Europe and among the lowest reported for Caucasian populations. However, the descriptive epidemiology is similar to that for high incidence populations. Further etiological studies are required to evaluate potential reasons for the very low incidence of IDDM in Macedonia.
