Risk factors associated with the presence of diabetes in Chinese communities in Beijing

ObjectiveTo identify risk factors associated with the presence of diabetes.MethodsA diabetes survey was conducted in 2801 citizens aged 35–79 years living in 10 communities in Beijing, China. Participants were recruited by residents committees. 75 g oral glucose tolerance test was performed to define diabetes according to the WHO 1999 criteria. Logistic regression analysis was used to estimate odds ratios (OR) for diabetes.ResultsThe prevalence of diabetes and impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT) was 24.2% and 20.4% in men, respectively and 19.4% and 19.0% in women, respectively. The multivariate adjusted OR (95% CI) corresponding to a one standard deviation increase in age (year) was 1.52 (1.25,1.86), waist circumference (cm) 1.35 (1.12,1.63), serum triglycerides (mmol/L) 1.29 (1.09,1.54) and high density lipoprotein cholesterol (mmol/L) 0.74 (0.61,0.91) in men and 2.03 (1.77,2.33), 1.21 (1.06,1.38), 1.34 (1.21,1.49), 0.74 (0.66,0.84) in women, respectively. For diabetes family history they were 2.46 (1.66,3.65) in men and 2.39 (1.84,3.10) in women, and for hypertension 1.14 (0.77,1.68) in men and 1.54 (1.18,2.01) in women. There were no significant associations between the presence of diabetes and occupation, education level, household income, leisure time physical activities, current smoking and drinking status.ConclusionsAge, diabetes family history, obesity, dyslipidemia and hypertension were all associated with the presence of diabetes in this study population.
