Abstract:

Objective To compare the nutrient intake of middle ⁃aged and elderly diabetic foot（DF） patients with different genders and different Wagner grades through dietary survey. Methods A total of 126 middle⁃ aged and elderly DF patients who were hospitalized in the Department of Endocrinology，Sun Yat ⁃ sen Memorial Hospital from August 2018 to December 2019 were included. Dietary frequency questionnaire was used to retrospec⁃ tively investigate the nutritional situation before admission. Results The total energy intake of DF patients was lower than that of dietary nutrient reference intake for Chinese residents. The percentage of energy intake of macro nutrients were basically in line with the reference intake of dietary nutrients. The intake of beans，eggs and milk， three high⁃quality protein sources，was generally insufficient. Intakes of calcium，potassium，phosphorus，magne⁃ sium，selenium，vitamin A，vitamin B1，vitamin B2，vitamin E and vitamin C failed to meet the dietary nutrient reference intakes for Chinese residents in more than 50% patients. Only the intake of iron，copper and niacin reach⁃ es 80%. Zinc intake exceeds 80% only in female patients. When the patients were grouped by DF classification， there was no significant difference in the intake of nutrient and food between group Wagner 3 and below and group Wagner 4. Conclusion In order to improve nutritional status and promote rehabilitation，patients with DF should increase the intake of beans，eggs，milk，and foods which are rich in minerals and vitamins such as calcium，po⁃ tassium，phosphorus，magnesium，selenium，vitamin A，vitamin B1，vitamin B2，vitamin E and vitamin C.
