OBJECTIVE: To describe the status of prevalence, awareness, treatment, and control of hypertension among half a million adults in 10 regions under the China Kadoorie Biobank (CKB) cohort. METHODS: The baseline survey of CKB was performed in 10 areas across China during 2004-2008, included 512 891 adults aged from 30 to 79 years. Regional differences of prevalence, awareness, treatment and control of hypertension were compared after adjustment for age and/or sex. RESULTS: The overall prevalence of hypertension from the CKB was 35.2% (180 612/512 891), with the highest as 44.4% in Zhejiang and the lowest as 22.0% in Haikou. Prevalence in the rural areas (35.1%) was higher than that in the urban areas (32.1%), with statistical significance (P<0.001). Among all the participants with hypertension, 59 703 (33.1%) were aware of hypertension, 65 172 (36.1%) were receiving anti-hypertension treatment and 22 329 (12.4%) were under controll. However, only a small part of those receiving treatment were under controll (30.5%, 19 884/65 172) in this study. The control of hypertension and of those receiving treatment were higher in Suzhou for males (17.4%, 39.1%), while were higher in Liuzhou for females (23.5%, 42.6%) than those in other regions. CONCLUSIONS: Participants under the CKB presented relatively high prevalence of hypertension, but lower rates on awareness, treatment and control of hypertension. Distribution of awareness, treatment, and control of hypertension varied greatly among the ten areas, under the CKB.
