Objective: To analyze the combination of hypertension and the use of antihypertensive drugs by different glucose tolerance status.
Methods: Matched case-control design was used to sample the subjects from the population for the prevalence of diabetes mellitus and metabolism syndrome from 2007 to 2008. There were 3 groups including normal glucose tolerance (NGT, n = 2124), impaired glucose regulation (IGR, n = 2162) and diabetes (DM, n = 2470). The matched factors were location, age and gender. All subjects were interviewed to describe the hypertension and antihypertensive drugs of these conditions.
Results: After adjusting for age, gender and location, the combination of hypertension in IGR and DM groups was higher than NGT (28.3%, 40.2% and 19.9%) and OR was 1.29 (1.08 - 1.53) and 1.99 (1.67 - 2.37) respectively. The percent of treatment, prescription compliance and the surveillance of hypertension in total subjects were 48.6%, 79.3% and 62.5%. And no difference was observed among 3 groups. The proportion of calcium channel blocker of DM groups was higher than NGT group. The uses of angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blocker (ARB) showed no difference among 3 groups.
Conclusions: The combination of hypertension is higher in IGR and DM groups than that in NGT group. And the treatment rate of hypertension remains low. ACEI and ARB are under-utilized in IGR and DM groups.
