Prevalence of type 2 diabetes and influencing factors in the elderly population aged 60 and above in western Hainan

  Objective   To investigate the prevalence and influencing factors of type 2 diabetes in the elderly population aged ≥60 years in the west of Hainan province and provide evidence for prevention and treatment of type 2 diabetes in the elderly.

  Methods   Using the multi-stage cluster random sampling method, the elderly population aged ≥60 years in four counties in western Hainan were selected for the investigation. The information about their general characteristics and lifestyle were collected, and physical examination and laboratory testing were carried out for them. Univariate and multivariate Logistic regression analysis were used to analyze the related influencing factor of elderly type 2 diabetes in the elderly.

  Results   A total of 12 582 subjects were included, and the prevalence rate of type 2 diabetes was 30.52% (3840/12582), with the highest prevalence rate of 32.24% (1 330/4 125) in those aged 70−79 years. The prevalence of type 2 diabetes in women (32.94%) was significantly higher than that in men (27.73%) (χ²=40.037, P<0.001). Multivariate Logistic regression analysis showed that overweight or obesity, family history of diabetes, hypertension, long term anxiety or tension, hyperuricemia and dyslipidemia were associated with a higher prevalence of type 2 diabetes in the elderly (P<0.05).

  Conclusion   The prevalence of type 2 diabetes in the elderly in western Hainan is relatively high, and the controlling body mass index, blood pressure, uric acid and blood lipids is of great significance to the prevention and control of type 2 diabetes in the elderly.
