BACKGROUND: With economic growth and urbanization there have been significant changes in the life style and diet of urban residents in large cities of China, which is experiencing a rapid increase in the prevalence of diabetes. While high prevalence of diabetes has been reported, little is known of the long-term effects of diabetes in such a large population. The aim of this study was to estimate the morbidity rate of diabetic peripheral neuropathy (DPN) in a Chinese urban diabetic population with more than 10 years' disease duration, and evaluate the relevant risk factors. The clinical manifestation of DPN and pain status was also assessed.
METHODS: Five hundred and sixty-five diabetes patients were recruited into the study. Symptoms and examination helped diagnose neuropathy. The clinical manifestation of DPN was assessed with a visual analog pain score (VAS). Diabetic complication status was determined from medical records. Serum lipids and lipoproteins, glycosylated hemoglobin (HbA1c), and the urinary albumin excretion rate were measured.
RESULTS: The morbidity rate of DPN was 46.6%. HbA1c, hyperlipidemia, and retinopathy were significantly associated with neuropathy, and these risk factors were correlated with other diabetic micro and/or macrovascular complications. The average VAS pain score of the DPN patients was 4.12 ± 2.07. Severe and moderate pain was experienced by 11.4% and 40.5% respectively of DPN patients. About 3.7% of diabetic subjects had lower limb ulcer or amputation.
CONCLUSIONS: The morbidity rate of DPN for diabetic patients with > 10 years duration is very high compared to the range reported for other populations in the world. The risk factors for DPN include HbA1c, hyperlipidemia, and retinopathy. In long-standing diabetic patients, DPN was not associated with diabetic duration, and half of the DPN patients experienced considerable daily suffering.
