Abstract

To study the relationship between blood pressure level and major risk factors for cardiovascular diseases in adults in China. A total of 179 347 adults aged ≥18 years were recruited from 298 surveillance points in 31 provinces in China in 2013 through complex multistage stratified sampling. The survey included face to face interview and physical examination to collect information about risk factors, such as smoking, drinking, diet pattern, physical activity, overweight or obesity, and the prevalence of hypertension. The blood pressure was classified into 6 levels (ideal blood pressure, normal blood pressure, normal high blood pressure and hypertension phase Ⅰ, Ⅱ and Ⅲ). The relationship between the prevalence or co-prevalence of risk factors for cardiovascular disease and blood pressure was analyzed. The adults with ideal blood pressure, normal blood pressure, normal high pressure, hypertension phase Ⅰ, Ⅱ and Ⅲ accounted for 36.14, 22.77, 16.22, 16.43, 5.97 and 2.48, respectively. Among them, the blood pressure was higher in men, people in Han ethnic group and those married, and the blood pressure was higher in those with older age, lower income level and lower education level, the differences were all significant (<0.05). Whether taking antihypertensive drug or not, co-prevalence of risk factors influenced the blood pressure levels of both sexes (<0.05), and the blood pressure levels of those taking no antihypertensive drug was influenced more by the co-prevalence of risk factors. Finally, multiple logistic analysis showed that the risks for high blood pressure in adults with 1, 2 and ≥3 risk factors were 1.36, 1.79 and 2.38 times higher, respectively, than that of the adults without risk factor. The more the risk factors for cardiovascular disease in adults, the higher their blood pressure were. It is necessary to conduct comprehensive behavior intervention targeting ≥ 2 risk factors for the better control of blood pressure in general population.
