Abstract:
Objective To determine the changes in the prevalence of type 2 diabetes mellitus and prediabetes in residents aged over 20 years in Shandong coastal areas during years 2004-2014. Methods A random stratified cluster sampling was conducted, and 3 944 inhabitants were investigated in Qingdao, Yantai, Weihai, and Rizhao regions. Results (1)The standardized rate of diabetes mellitus prevalence was 10.36% in 2014, increased by 2.38% as compared with 2004 and 0.85% as compared with 2009 (P<0.05). There were 341 newly diagnosed diabetes mellitus patients, accounting for 57.4% of the diabetes mellitus patients, increased by 6.09% as compared with 2004 and decreased by 4.11% as compared with 2009 (P<0.05). The standardized rate of prediabetes was 12.47% in 2014, increased by 2.63% as compared with 2004 and 0.61% as compared with 2009 (P<0.05). (2) The prevalence of diabetes mellitus and impaired glucose regulation in individuals aged under 50 years in 2014 was significantly higher than that in 2004, but lower than that in 2009 (P<0.05). (3) Compared with 2004 and 2009, the levels of diastolic blood pressure, total cholesterol, low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol in subjects with prediabetes and diabetes mellitus increased significantly in 2014 (all P<0.05). The levels of serum uric acid in subjects with prediabetes and diabetes mellitus decreased significantly in 2014 (P<0.05). (4) The logistic regression analysis showed that the age, body mass index, waist-hip ratio, triglyceride, LDL-C, systolic blood pressure, and diabetic family history were the risk factors for abnormal glucose regulation, while total cholesterol was the protective factor. Conclusions The prevalence of diabetes mellitus and prediabetes increased during 10 years (2004-2014), but the growth rate dropped precipitously during last five years as compared with the first five years. The age of diabetes mellitus onset is getting older in residents of Shandong coastal area, especially in females. Aging, overweight, hypertension, lipid disorders, and diabetic family history were the risk factors of diabetes mellitus.
