Incidence of Insulin-Dependent Diabetes Mellitus in Young Adults: Experience of1,587,630 U.S. Navy Enlisted Personnel

摘要

Computerized medical and career records of active-duty Navy enlisted personnelserving from 1974 to 1988 (7,245,026 person-years) were examined for first hospitalizations for diabetes mellitus; and 2,408 incident cases were found. The overall incidence rate was 33.2 per 100,000 person-years. Diabetes incidence rates per 100,000 person-years were higher in men (34) than women (27) (p < 0.05), and in blacks (48) than whites (29) (p < 0.05). Incidence increased with increasing age, particularly in blacks. Incidence rates per 100,000 person-years at ages 17-19 were 17 in white males and 16 in black males. At ages 40-44 years, incidence rates per 100,000 person-years increased approximately 9-fold in white males (111), and nearly 22-fold in black males (354). Elevated Standardized Incidence Ratios (SIRs) occurred in several unrelated occupations, suggesting that diabetes risk may not be strongly related to occupational factors.
