Objective: To investigate the risk factors of elevated urinary microalbumin in elderly patients with type 2 diabetes mellitus.Methods:The clinical data of 382 elderly patients with type 2 diabetes mellitus admitted to the hospital from July 2016 to October 2021 were reviewed. The elevation of urinary microalbumin in elderly patients with type 2 diabetes mellitus was analyzed, who were then divided into occurrence of elevated urinary microalbumin and none. The risk factors associated with elevated urinary microalbumin in elderly patients with type 2 diabetes mellitus were summarized and the composition ratio of possible risk factors in elderly patients with and without type 2 diabetes mellitus was compared. Risk factors for elevated urinary microalbumin in elderly patients with type 2 diabetes mellitus were investigated by logistic regression analysis.Results:A total of 84 patients in this group developed elevated urinary microalbumin, with an incidence rate of 21.99%. The patients with BMI≥25 kg·m-2, course of diabetes≥5 years, substandard fasting blood glucose(FBG) not up to standard, substandard postprandial blood glucose(2hPBG), substandard glycosylated hemoglobin(HbAlc), insulin resistance index(HOMA-IR)≥2.77, hyperlipidemia, hypertension, coronary heart disease and hyperuricemia were all higher than those without(P<0.05). Logistic regression analysis showed that BMI≥25 kg·m-2, course of diabetes≥5 years, substandard blood glucose,HOMA-IR≥2.77, hyperlipidemia, hypertension, coronary heart disease, hyperuricemia were independent risk factors for the rise of urinary microalbumin in elderly patients with type 2 diabetes mellitus(P<0.05).Conclusion:Elderly patients with type 2 diabetes mellitus have the risk of increasing urinary microalbumin, and BMI≥25 kg·m-2, duration of diabetes≥5 years, substandard blood glucose, HOMA-IR≥2.77, combining with hyperlipidemia, hypertension, coronary heart disease and hyperuricemia are the risk factors, which need strengthened prevention and control. |
