The aim of this study was to investigate trends in the distribution, prevalence, awareness, treatment, and control of hypertension in a Chinese population that has had the fastest growing gross domestic product in the world over the past 3 decades.Four standardized cross-sectional health surveys were conducted between 2002 and 2010 in a population consisting of 85 million residents in Guangdong Province. Multistage cluster sampling was adopted to recruit representative samples. The data were obtained through on-site health examinations and face-to-face interviews.The aging trend in this population was not significant (P = 0.17) during the survey period, whereas body mass index/waist circumference increased significantly (P = 0.047 for body mass index and P < 0.001 for waist circumference). The age-standardized prevalence of hypertension increased from 10.5% to 13.3%, averaging a 0.35% increase per year. A higher risk was observed in younger residents over the survey period. Awareness and treatment increased by 22.0% and 19.0%, respectively, in the rural areas, whereas there was no significant change in the urban area (the corresponding figures were 1.8% and −3.1%, respectively). There was no improvement in hypertension control (the age-standardized control prevalence in 2002 was 50.3%, whereas it was 43.2% in 2010).The prevalence of hypertension increased slightly in this population with the fastest economic development. This increase mirrored the trend of increasing obesity. Awareness and treatment of hypertension have improved in the rural areas, although there were no significant changes in the urban areas. The prevalence of awareness and treatment remains at unacceptably low levels, suggesting that urgent and aggressive strategies are necessary to improve hypertension control and intervention.
