[Results of a carbohydrate tolerance study in prospective epidemiological research on ischemic heart disease].

There are presented the results of a prospective study aimed at establishing the incidence of impaired carbohydrate tolerance in a nonorganized population of middle-aged males, which in a 6.5-year follow-up accounted for 42.2 and 40.3%, respectively. The incidence of diabetes mellitus increased drastically with age (3.1% and 9.8% in 50-54 and 60-64 year-old men, respectively). Men with borderline impaired carbohydrate tolerance combined with glucosuria require the most thorough dispensary follow-up, for they were found to develop diabetes mellitus in 6.3% of cases during the following 6.5 years.
