[Prevalence and control status of diabetes in elderly community residents and risk factors]

Objective: To analyze the prevalence and control status of diabetes in elderly community residents and related risk factors. Methods: A population-based cross-sectional study was conducted in elderly community residents aged 60-95 years in an urban district of Beijing from September 2009 to June 2010 to collect the general health status of the elderly in the community, the prevalence of diabetes, medication treatment, and laboratory tests were conducted. Results: A sample of 2 102, including 848 males and 1 254 females, were selected through randomized clustering sampling for this study. Most participants had higher educational levels, and the smoking and drinking rates were low among them. The prevalence of diabetes, impaired fasting glucose and impaired glucose tolerance were 24.8%, 2.5% and 30.6%, respectively. The awareness, treatment and control rates of diabetes were 78.5%, 69.3% and 15.9%, respectively. Multivariate logistic regression analysis showed that ORs of obesity, family diabetes history for diabetes were 1.42 (95%CI: 1.14-1.76) and 3.42 (95% CI: 2.70-4.35), respectively compared with control group. Also, obesity and family diabetes history were related risk factors for control status of diabetes. Conclusions: The prevalence of diabetes was relatively high, but the control rate was low in elderly community residents. Obesity, unhealthy lifestyles and family diabetes history were related risk factors.
