[A survey of microalbuminuria prevalence in hypertensive type 2 diabetic patients in mainland China].

OBJECTIVE
To determine the prevalence and risk factors of microalbuminuria (MA) in diabetic patients with hypertension in mainland China.


METHODS
This cross-sectional study involved 2473 patients enrolled from 42 diabetic and cardiac outpatient clinics. An immunospecific dipstick Micral Test II was used for MA screening and Nephur7 urinary strip for macroalbuminuria. In addition, blood pressure levels were recorded and questionnaire forms were filled out. Chi square and logistic regression analyses were used for statistical analyses.


RESULTS
In the study population the prevalence of MA in hypertensive type 2 diabetic patients was 42.9% and that of macroalbuminuria was 17.0%. Logistic regression analysis showed that age, BMI and systolic blood pressure were independently associated with the occurrence of MA, while the duration of type 2 diabetic and diuretics used were independently associated with the occurrence of macroalbuminuria.


CONCLUSIONS
It is shown that there is a high prevalence of MA in hypertensive diabetic patients. Screening of MA and lowering of blood pressure should be the important measures for lowering its occurrence.
