Abstract: Objective To investigate the relationship between albuminuria,blood pressure and dysglycaemia in patients with essential hypertension in China’s five regions. Methods Fifty hundred twenty-one patients with clearly diagnosed essential hypertension and without diabetes were enrolled in. The mean age of participants was （62.2±12.0） years old. Among them,2492 were male （49.6%） and the other 2529 were female （50.4%）. The urine routine examination was performed,creatinine concentration was measured and the urine albumin/creatinine ratio was calculated in all these patients. Twice abnormal albumin/creatinine ratio or urine protein more than 0.3 g/L and no WBC or RBC in urine routine examination was defined as positive albuminuria. In patients with fasting blood glucose more than 5.6 mmol/L,simple oral glucose tolerance test （only 2 hours glucose level after drinking 75 g-glucose-water was measured） were performed. The association of albuminuria,blood pressure level and dysglycaemia were analyzed. According to the blood pressure level,patients were divided into controlled group（blood pressure ＜140/90 mm Hg,n=2236） and uncontrolled group （blood pressure ≥140/90 mm Hg,n=2785）. According to the glucose level,patients were divided into normal glucose group （n=3600）,impaired glucose regulation group （fasting glucose ≥5.6 and ＜7.0 mmol/L and （or） oral glucose tolerance test 2 hour glucose ≥7.8 and ＜11.1 mmol/L,n=1067） and diabetes group （fasting glucose ≥7.0 mmol/L or oral glucose tolerance test 2 hour glucose ≥11.1 mmol/L,n=354） respectively. Results ①The total albuminuria detection rate was 28.8%,which was increased with the increasing of blood pressure. ②28.3% patients complicated with dysglycaemia. The higher the blood glucose level,the more the urine protein excretion （normal glucose group 26.3%,impaired glucose regulation group 32.6%,diabetes group 42.3%）. ③Compared with controlled blood pressure group,more patients complicated with diabetes in uncontrolled blood pressure group（5.8% vs 8.1%,P=0.006）. ④Patients with dysglycaemia had more heart,cerebral and renal events（46.0% vs 37.3%）. Conclusion Uncontrolled blood pressure and dysglycaemia were important risk factors of albuminuria in patients with essential hypertension.
