Diabetes mellitus incidence and prevalence in Moscow

Abstract

Epidemiologic survey of two diabetes mellitus types in Moscow has shown that the incidence of type I diabetes markedly increases from birth (0.012-0.013%) to the age of 10-14 (0.04-0.045 %), after which somewhat reduces (0.02-0.03 %) and thus persists up to 40. Type I diabetes prevalence increases from 0.002-0.004 % at the age of 0 to 4 years to 0.14-0.092 % by the age of 35-39 in men and women, respectively. Type II diabetes is diagnosed after the age of 20. At the age of 20 to 24 this diabetes incidence is lower than that of type I condition; at the age of 25-34 the incidence of both is approximately the same, and after 35 the incidence of type II is much higher than that of type I diabetes. Type II diabetes prevalence by the age of 40 is 0.074 and 0.122% in men and women, respectively. Prevalence of diabetes cases treated with diets and oral sugar-reducing drugs at the age 75 and older is 4.3 % in men and 5.5 % in women, of insulin- treated cases 1.2 and 0.5 %, respectively. The true prevalence of type II diabetes is however higher and that of type I condition lower than the resultant values; this is explained by a frequent prescription of insulin to elderly patients with type II diabetes because of complications or concomitant diseases.
