Popis: Background: Because amputation negatively affects the quality of life of patients with diabetes and increases the risk of cardiovascular events and mortality, predictors of amputation must be identified. However, no large cohort studies have been conducted regarding the incidence of amputation in patients with diabetes in East Asia.Methods: We analyzed data from a nationwide claims database in Japan accumulated from 2008–2016, involving 17,288 patients with diabetes aged 18–72 y (2942 women, mean age 50.2 y, HbA1c 7.2%).Results: The mean follow-up time was 5.3 years, and 16 amputations occurred (0.17/1000 person-years). Multivariate Cox regression analysis showed that age and HbA1c levels were independent predictors of amputation (hazard ratios [HRs], 1.09 and 1.43; 95% confidence intervals [CIs], 1.01–1.16 and 1.12–1.82, respectively). Compared with patients aged Conclusions: Improved glycemic control may lower amputation risk.
