Hypertension prevalence, awareness, treatment and control among Han and four ethnic minorities (Uygur, Hui, Mongolian and Dai) in China.

In the previous study, hypertension prevalence, awareness, treatment and control for Han and others four ethnic minorities (Uygur, Hui, Mongolian and Dai) has not been clearly documented in China. Therefore we used the baseline data of Prospective Urban and Rural Epidemiology (PURE) for further detailed study. Adjusted rate were estimated and compared through logistic regression after adjustment of age, sex, location and education. Among the total of 7137 participants (Han: 1626, ethnic minorities: 5511), hypertension prevalence, awareness, treatment and control were 2922(40.9%), 1199(41.0%), 873(29.9%) and 147(5.0%), respectively. The most commonly used antihypertensive drugs are traditional compound drugs (6.2%) and calcium channel blockers (5.2%). Hypertension prevalence in ethnic minorities was significantly higher than in Han (42.4% vs 34.4%, P<0.0001), while control rate (1.6% vs 9.8%, P=0.0198) and treated control rate (8.0% vs 25.0%, P=0.0200) were lower. Compared with Han counterparts, Dai had a higher prevalence (50.8% vs 29.9%, P<0.0001). Uygur had a lower treatment rate (33.2% vs 20.6%, P=0.0110). Mongolian had a lower control (5.1% vs 16.1%, P=0.0046) and treated control rate (14.1% vs 50.3%, P=0.0013). In conclusions, our study showed ethnic minorities had higher hypertension prevalence, especially for Dai and lower control and treated control rate for Mongolian. Hence, we need more attention with respect to hypertension in ethnic minorities.
