Prevalence of diabetes and determinants: evidence from a minority region in People's Republic of China.

Abstract

BackgroundThis study aimed to examine the prevalence of diabetes mellitus and other categories of glucose intolerance (impaired glucose tolerance and impaired fasting glucose) and explore the risk factors in an ethnic minority region, Guangxi Zhuang Autonomous Region, People’s Republic of China.MethodsA population-based study enrolled 53,270 residents older than 5 years in Guangxi, People’s Republic of China. The prevalence of diabetes was calculated using the 1999 World Health Organization (WHO) oral glucose tolerance test diagnostic criteria.ResultsAmong 53,270 individuals, the prevalence of diabetes, impaired glucose tolerance, and impaired fasting glucose was 5.96%, 7.36%, and 2.62%, respectively. Of the 3,173 individuals with diabetes mellitus, 696 (21.94%) were found to have a history of diabetes and 2,477 (78.06%) were newly diagnosed. A lower prevalence was found in Zhuang ethnic minority people compared with the majority of Han people. The prevalence was significantly associated with age, body mass index, waist-to-hip ratio, dyslipidemia, medical history of hypertension, and family history of diabetes.ConclusionGuangxi shows a rapidly rising prevalence of diabetes. Weight control and blood lipid control are important to decrease the rapidly increasing prevalence of diabetes in Guangxi, an ethnic minority region.
