Abstract
OBJECTIVE: The degree to which mortality and cardiovascular disease (CVD) incidence remains elevated in young U.S. adults with type 1 diabetes (T1DM) is unclear. We determined contemporary rates for adults <45 years old with long-standing, childhood-onset T1DM from the Pittsburgh Epidemiology of Diabetes Complications (EDC) Study. RESEARCH DESIGN AND METHODS: Members of the EDC Study cohort <45 years old during the 1996–2012 follow-up period (n = 502) were studied. Mortality and CVD rates were calculated for those aged 30–39 and 40–44 years. Data from the background Allegheny County, Pennsylvania, population were used to calculate age- and sex-matched standardized mortality (SMR) and incidence rate ratios (IRR). RESULTS: In both age groups, the SMR for total mortality was ∼5 (95% CIs: 30–39-year-olds, 2.8, 7.2; 40–44-year-olds, 3.4, 7.8). CVD mortality SMRs ranged from 19 (95% CI 11, 32) to 33 (95% CI 17, 59). Hospitalized CVD IRR was ∼8 (95% CIs: 30–39-year-olds, 2.5, 18.9; 40–44-year-olds, 4.5, 12.8); revascularization procedures account for much of the increased risk. For all outcomes, the relative risk was larger in women. Participants aged 30–39 years had 6.3% (95% CI 3.8, 9.8) absolute 10-year CVD risk, approaching the American College of Cardiology/American Heart Association–recommended cut point of 7.5% for initiation of statin therapy in older adults. CONCLUSIONS: Total and CVD mortality and hospitalized CVD are all significantly increased in this contemporary U.S. cohort of young adults with long-standing T1DM. These findings support more aggressive risk factor management in T1DM, especially among women.Keywords
