ABSTRACT

<p><b>OBJECTIVE</b>To identify the prevalence and risk factors of diabetes and prediabetes in the community residents above 18 years old in the suburbs of Guangzhou.</p><p><b>METHODS</b>Between April and May in 2008, the residents above 18 years living in 6 communities of Guangzhou for 5 or more years were sampled with multistage clustering sampling. The sampled residents were surveyed by questionnaires, and physical examination and glucose determination were carried out.</p><p><b>RESULTS</b>A total of 1532 residents were sampled. The incidence of diabetes mellitus in these community residents was 8.46%, and that of impaired glucose regulation was 6.59%. Age, body mass index, family history of diabetes mellitus, case history of hypertension, hyperlipidemia, hypertension and smoking were all the independent risk factors for impaired glucose regulation and diabetes mellitus.</p><p><b>CONCLUSION</b>Diabetes and prediabetes are prevalent in the community residents in Guangzhou. Controlling the risk factors such as obesity, hypertension, lipid metabolism disorder among the residents above 40 years with a family history of diabetes mellitus and hypertension is key to prevention of impaired glucose regulation and diabetes mellitus.</p>
