Low incidence of childhood IDDM in district of Novosibirsk (Russia).

Objective: To study the incidence of insulin-dependent diabetes mellitus (IDDM) among 0- to 14-yr-old children of the district of Novosibirsk, in western Siberia, Russia, from 1983 to 1989.
Research Design and Methods: Data were collected with methods recommended by the Diabetes Epidemiology Research International Group.
Results: The average yearly incidence among males and females was 4.7 (95% confidence interval 3.9-5.8) and 4.4 (95% confidence interval 3.6-5.4) per 100,000 people, respectively. The incidence of IDDM among children living in the city of Novosibirsk was significantly higher than in children living in the surrounding counties of the district, 5.7/100,000 (95% confidence interval 4.8-6.8) versus 3.6/100,000 (95% confidence interval 2.9-4.5).
Conclusions: The incidence of childhood IDDM among Russians in Siberia is low. This is the first publication of internationally comparable data on the occurrence of childhood IDDM in the Russian population.
