This study aimed to evaluate the association between total bilirubin (TBiL) and major diabetic complications among Chinese senile diabetic patients.MethodsA cross-sectional study was conducted in all the cadre sanitariums in Beijing, between May 2012 and December 2014. All the diagnoses of diabetic complications were extracted from the medical records including chronic kidney disease, retinopathy, peripheral vascular disease, coronary heart disease, and ischemic stroke.ResultsThe mean age of the 1839 senile diabetic patients were 87.4 ± 4.0 (80–102 years) and mean TBiL level was 13.2 ± 6.0 μmol/L. The prevalence of chronic kidney disease, retinopathy, peripheral vascular disease, coronary heart disease and ischemic stroke was 13.8%, 17.8%, 5.8%, 62.5%, and 44.5%, respectively. TBiL level was negatively correlated with age, weight, SBP, TC, FBG, 2hPG, diabetic duration and positively correlated with HDL-C. Prevalence of all five diseases gradually decreased with the increase of TBiL level (p < 0.05). Also, number of diabetic complications showed a decreasing trend along with TBiL tertiaries. After adjusted age, education, marital status, current smoking, current drinking, physical activity ≥ 0.5 h/day, BMI, hypertension, dyslipidemia, treatment and control status of diabetes, patients with higher TBiL level were at significantly decreased ORs for prevalence of major diabetic complications. The ORs were 0.97 (95%CI: 0.96–0.99), 0.90 (95%CI: 0.87–0.93), 0.98 (95%CI: 0.97–0.99), 0.97 (95%CI: 0.95–.99) and 0.98 (95%CI: 0.97–0.99) for chronic kidney disease, retinopathy, peripheral vascular disease, coronary heart disease and ischemic stroke (p < 0.005). Similar results were obtained when TBiL was used as tertiary variable.ConclusionHigher TBiL was significantly associated with lower prevalence of major diabetic complication among senile diabetic patients, and this association was graded with TBiL level and independent of age and control status of diabetes.
