OBJECTIVE: To examine the magnitude and types of hospitalizations among persons with prediabetes, undiagnosed diabetes, and diagnosed diabetes. RESEARCH DESIGN AND METHODS: This study included 13,522 participants in the Atherosclerosis Risk in Communities (ARIC) study (mean age 57 years, 56% female, 24% black, 18% with prediabetes, 4% with undiagnosed diabetes, 9% with diagnosed diabetes) with follow-up in 1990-2011 for hospitalizations. Participants were categorized by diabetes/HbA1c status: without diagnosed diabetes, HbA1c <5.7% (reference); prediabetes, 5.7 to <6.5%; undiagnosed diabetes, ≥6.5%; and diagnosed diabetes, <7.0 and ≥7.0%. RESULTS: Demographic adjusted rates per 1,000 person-years of all-cause hospitalizations were higher with increasing diabetes/HbA1c category (Ptrend < 0.001). Persons with diagnosed diabetes and HbA1c ≥7.0% had the highest rates of hospitalization (3.1 times higher than those without a history of diagnosed diabetes, HbA1c <5.7%, and 1.5 times higher than those with diagnosed diabetes, HbA1c <7.0%, P <0.001 for both comparisons). Persons with undiagnoseddiabetes had1.6 times higher rates of hospitalization and those with prediabetes had 1.3 times higher rates of hospitalization than those without diabetes and HbA1c <5.7% (P < 0.001 for both comparisons). Rates of hospitalization by diabetes/HbA1c category were different by race (Pinteraction = 0.011) and by sex (Pinteraction = 0.020). There were significantly excess rates of hospitalizations due to cardiovascular, endocrine, respiratory, gastrointestinal, iatrogenic/injury, neoplasm, genitourinary, neurologic, and infection causes among those with diagnosed diabetes compared with those without a history of diagnosed diabetes (all P < 0.05). CONCLUSIONS: Persons with diagnosed diabetes, undiagnosed diabetes, and prediabetes are at a significantly elevated risk of hospitalization compared with those without diabetes. Substantial excess rates of hospitalizations in persons with diagnosed diabetes were for endocrine, infection, and iatrogenic/injury causes, which may be preventable with improved diabetes care.
