ObjectiveTo investigate the prevalence of diabetes and impaired glucose regulation in high risks community residents in Songjiang District of Shanghai, and to explore the risk factors affecting their blood glucose metabolism, providing effective suggestions for improving community diabetes prevention and treatment.

MethodsQuestionnaire, physical examination and laboratory testing were used to collect information on the basic characteristics and blood glucose levels of 21 035 residents in Songjiang District who were assessed to be at high risk of diabetes.

ResultsA total of 3 008 people with impaired regulation and 2 241 patients with diabetes were detected.The detection rates were 14.3% and 10.6%, respectively.It was found that as the residents′ age was higher, their education level was lower, high-risk factors for them were numerous, and their detection rates of diabetes and impaired sugar regulation were higher.It was found that age, gender, history of impaired glucose regulation, relatives with type 2 diabetes, hypertension, dyslipidemia and overweight/obesity were all factors influencing blood glucose metabolism (P < 0.05).

ConclusionBlood glucose screening in high-risk population of diabetes is helpful for the early detection of diabetic patients and those with impaired glucose regulation.It is necessary to strengthen the attention of population at risk of diabetes and take appropriate interventions.
