title: The dynamics of hypertension prevalence, awareness, treatment, control and associated factors in Chinese adults: results from CHNS 1991-2011.
abstract: OBJECTIVE
  To analyze the trends in blood pressure (BP), and the prevalence, awareness, treatment and control of hypertension and associated factors in Chinese adults from 1991 to 2011.
  
  
  METHODS
  On the basis of the longitudinal data of China Health and Nutrition Survey, 75 526 records of 24 410 adults were selected according to the eligibility criteria. The age-standardized levels of SBP, DBP, prevalence, awareness, treatment and control of hypertension were calculated by sex and age group within each year. Generalized estimating equation was employed to investigate the associations between demographic factors and status of hypertension, awareness, treatment and control.
  
  
  RESULTS
  From 1991 to 2011, the BP level elevated (SBP 120.0-124.5 mmHg, DBP 76.7-79.3 mmHg) and the prevalence of hypertension increased from 23.4 to 28.6%. The increasing levels of BP and hypertension prevalence were more apparent among men and older patients. The rates of hypertension awareness, treatment and control also increased while kept at low levels. Factors such as age, sex, smoking habit, drinking habit, household income, health insurance, BMI, residential region, marital status, educational level and nationality were significantly associated with the status of hypertension, awareness, treatment and control.
  
  
  CONCLUSIONS
  The BP level and hypertension prevalence have increased among Chinese adults in recent years. However, levels of hypertension awareness, treatment and control were quite low. To reduce the disease burden of the hypertension, improvements in health education programs, detection and treatment strategies are warranted.
