1511-P: Trend in the Prevalence of Diabetes between 2002-2009 in Populations in Qingdao, China

The current study aims to determine the secular trend of prevalence of type 2 diabetes and prediabetes and risk factors for diabetes from 2002 to 2009. We conducted 3 population-based surveys for diabetes in individuals aged 35-74 years in Qingdao in 2002, 2006 and 2009, respectively, with random-sampling approach. The sample size was 1792, 4549 and 4310 in 2002, 2006 and 2009, respectively. We performed a questionnaire-based survey to collect general information. All participants underwent standardized 2-h 75-g oral glucose tolerance tests (OGTTs). The 1999 WHO diagnostic criteria for diabetes and prediabetes was applied. Age-standardized prevalence of diabetes was calculated. Multiple non-conditional logistic regression were applied to analyze the risk factors for diabetes, taking diabetes as the dependent variable. In 2002, the age-standardized prevalence of diabetes was 12.32%, the corresponding prevalence was 16.57% and 18.01%, respectively, in 2006 and 2009. The prevalence of diabetes increased from 2002 to 2009 (p Disclosure L. Zhang: None. W. Gao: None. N. Wang: None. J. Wang: None. X. Yin: None. Y. Zhu: None. Y. Dong: None.
