Abstract

BACKGROUND:

Hypertension is a major cause of cardiovascular disease. Periodic nationwide surveys are essential for monitoring secular trend of hypertension and its control in population. We assessed prevalence of hypertension and related awareness, treatment and control rates in Chinese adults in 2013-14.

METHODS:

A nationally representative survey recruited 174,621 adults aged>18years from 31 provinces in mainland China between 2013 and 2014. Population-weighted prevalence of hypertension and related rates of awareness, treatment and control were calculated and compared by age, sex, region and other factors of interest.

RESULTS:

Overall, 27.8% of Chinese adults were hypertensive, with the adjusted prevalence higher in men than in women and increasing steeply with rising age. Of those with hypertension, 31.9% were previously diagnosed, of those diagnosed, 82.9% were treated, and of those treated, 34.6% had their blood pressure properly controlled, resulting in an overall control rates of 9.7% among those with hypertension. Despite similar prevalence, the awareness, treatment and control were much better in urban areas than in rural areas. Among hypertensive individuals, older age, higher levels of education or household income tended to be associated with better awareness, treatment and control rates. During 2013-14, 292 million adults in China had hypertension, representing an absolute increase of 139 million individuals since year 2002.

CONCLUSIONS:

Among Chinese adults, more than one forth had hypertension and the prevalence has increased significantly during recent decades. Despite huge efforts, the levels of awareness, treatment and control rates of hypertension remain extremely low, foreshadowing substantial unnecessary disease burden.
