2014
Objective To access the prevalence of type 2 diabetes mellitus (T2DM) and its associated risk factors among adults with obesity in Zhejiang province. Methods The enrolled subjects were selected among local residents aged ≥18 years with body mass index ≥28 kg/m2 from 15 counties by multi stage stratified cluster random sampling from July to November, 2010. Each participant was required to attend complete questionnaire, physical examination, and testing overnight fasting blood specimen. Results A total of 1 351 residents were enrolled, including 613 males and 738 females. The prevalence of T2DM in adult population with obesity was 15.03% , being 14.03% in male, and 15.85% in female; and that in urban area was 16.64% , and in rural area was 13.93%. Data from multivariable logistic regression showed that factors such as ageing ( OR = 1. 473, 95% CI 1. 243-1. 747 ), a family history of T2DM ( OR = 8. 945, 95% CI 5. 481-14. 598 ), staple food intake ( OR = 1. 185, 95% CI 1. 017- 1. 380) , triglyceride ( ≥ 1.7 retool/L, OR = 1. 542,95% CI 1. 066-2. 232) were risk factors of T2DM ; while annual income ( OR = 0.695, 95 % CI O. 544-0. 888 ) , and milk intake ( OR = 0.750, 95 % CI 0. 567-0. 993 ) were shown as protective factors. Conclusion The prevalence of T2DM in adults with obesity was raised, ageing, a family history of T2DM, staple food intake, and dyslipidemia appeared to be major risk factors for T2DM.
