Abstract: AIM To investigate the correlative factors of hypertension complicated with newly diagnosed diabetes. METHODS A total of 468 patients with hypertension complicated with newly diagnosed type 2 diabetes were selected for study group and 468 patients with simple essential hypertension served as controls. RESULTS Significant differences were found in body mass index (28.8±3.9) kg/m² vs.(25.1±3.2) kg/m², P<0.05, HbA1c (9.4±1.6)% vs.(6.0±0.4)%, P<0.05, total cholesterol (4.8±1.4) mmol/L vs.(3.2±0.8) mmol/L, P<0.05 and triglyceride (2.2±1.3) mmol/L vs.(1.6±0.8) mmol/L, P<0.05 between study group and controls. Logistic regression analysis showed that total cholesterol and triglyceride were high risk factors for primary hypertension complicated with newly diagnosed diabetes mellitus OR=2.349 (95%Cl:2.10-3.308), OR=1.903 (95%Cl:1.508-2.267). Multiple linear regression indicated that HbA1c was associated with total cholesterol. CONCLUSION Triglyceride and total cholesterol are the risk factors of hypertension complicated with newly diagnosed diabetes mellitus and HbA1c is positively correlated with total cholesterol.
