Epidemiological Characteristics of Diabetic Foot and Affecting Factors for Amputation in China

Abstract

With the increased prevalence of diabetes from 0.67% in 1980 to 11.2% in 2017, the prevalence of diabetic foot has been growing in China in recent years. Diabetic foot ulcer (DFU) was one of the most serious complications of diabetes. Complicated general condition, severe infection and poor outcomes were feature characteristics of Chinese DFU patients. The annual incidence of DFU in China was as high as 8.1% in patients with diabetes, which ranked the first among the causes of chronic wounds in hospitalized patients [1-2]. And the recurrence rate of foot ulcers in healed DFU patients over 50-year-old was as high as 31.6% within one year [1].
