Factors Associated With Hypertension Awareness, Treatment, and Control in a Representative Sample of the Chinese Population

Abstract

We studied factors associated with awareness, treatment, and control of hypertension (systolic/diastolic blood pressure measurements ≥140/90 mm Hg, respectively, and/or current drug treatment for hypertension) in a representative sample of the Chinese population (n=15 838). Awareness, treatment, and control were defined by self-report of a hypertension diagnosis, self-report of current antihypertensive medication use, and a systolic and diastolic blood pressure <140/90 mm Hg, respectively. Higher awareness (OR; 95% CI) was noted for persons who were married (1.43; 1.09, 1.88) and had their blood pressure measured in 1 year (47.4; 31.7, 70.4) or 1 to 5 years (11.4; 7.09, 18.2) preceding their study visit; lower awareness was found among men (0.62; 0.52, 0.74) and current smokers (0.79; 0.63, 0.99). Among those aware of their hypertension, treatment was more common (OR; 95% CI) at higher income (1.24 [0.87, 1.75], 1.46 [1.01, 2.12] and 1.58 [1.06, 2.37] for increasing versus the lowest quartile of income) a...
