Abstract:
BACKGROUND: The incidence of diabetic peripheral neuropathy (DPN) is affected by various related factors, which can manifeste in patients with simple diabetes mellitus. However, which of these factors are involved in the occurrence of DPN in diabetic patients?OBJECTIVE: To analyze the risk factors for DPN in patients with type 2 diabetes mellitus.DESIGN: A hospital-based one-to-one pair-matched case-controlled investigation.SETTING: School of Public Health, Tianjin Medical University.PARTICIPANTS: Totally 111 outpatients or inpatients with DPN (DPN group) were recruited from the Metabolic Disease Hospital of Tianjin Medical University from December 2002 to November 2003, including 53 males and 58 females. Inclusive criteria: Diagnosed according to the diagnostic standards for diabetes mellitus recommended by American Diabetes Association (ADA) in 1997; Typing for type 2 diabetes mellitus according to the program by ADA in 1997; Decline or disappearance of achilles tendon reflex, knee tendon reflex, etc.; Decline or disappearance of pain sensation and thalposis; Decline or disappearance of diapason vibration sense. Meanwhile, 111 outpatients or inpatients with simple diabetes mellitus were selected as the control group. Informed consents were obtained from all the subjects.METHODS: The patients were investigated at admission or in the outpatient department with self-designed questionnaires, including more than 80 items of general information, past history, family history, etc. The results of laboratory examinations were recorded. The data were catalogized and input into computer. Multivariate conditional logistic regression was used to establish main effect equation for analyzing the risk factors for DNP.MAIN OUTCOME MEASURES: Risk factors for DNP.RESULTS: All the 111 patients with DNP and 111 patients with simple diabetes mellitus were involved in the analysis of results. The protective factors for DNP included higher educational level, intensive treatment, coronary heart disease and tea drinking. The risk factors for DNP included longer duration of diabetes mellitus, poor situation of blood sugar control, treating with insulin, diabetic nephropathy, diabetic retinopathy, history of diabetic ketonemia, more meat intake before diabetes mellitus, vertigo, dryness of skin, hypertension, history of injury, history of smoking, higher waist-to-hip ratio, higher level of blood cholesterol. The results of multivariate Logistic regression analysis showed that the following factors were significantly associated with DPN: longer duration of diabetes mellitus, treating with insulin, vertigo, more meat intake before diabetes mellitus, alcohol drinking and history of injury (operation, frostbite, etc.).CONCLUSION: DPN is related to various risk factors, such as longer duration of diabetes mellitus, treating with insulin, vertigo, alcohol drinking, more meat intake before diabetes mellitus, history of injury, etc., which all can increase the risk of diabetic neuropathy in patients with type 2 diabetes mellitus. Patients and physicians should pay more attention to these risk factors during the course of prevention and treatment.
