Risk characteristics of hypertension in high-risk population： an analysis based on the surveillance data of chronic diseases in Shanghai

ObjectiveTo understand the epidemiological characteristics of high-risk population of hypertension in Shanghai， and to provide references for health management and targeted lifestyle intervention of the high-risk population in community.

MethodsThe data from the 2013 Shanghai Non-communicable and Chronic Diseases Surveillance were used. The subjects who met the criteria of high-risk population of hypertension were included， and 11 753 subjects were finally identified， to analyze the distribution and level of risk characteristics.

ResultAmong six high-risk characteristics of hypertension， the detection rate of high salt in diet was the highest （55.3%）， followed by overweight/obesity （44.0%）， family history of hypertension （41.6%）， and blood pressure level of （130-139）/（85-89） mmHg （31.7%）. The detection rate of excessive drinking was the lowest （5.0%）. The percentage of population with one or two high-risk characteristics was higher than that with three or more high-risk characteristics （76.9% vs. 23.1%）. Systolic blood pressure， diastolic blood pressure， fasting plasma glucose level， and body mass index in the male high-risk group were higher than those in the female group， and the differences were statistically significant （P<0.05）. Systolic blood pressure， diastolic blood pressure， fasting plasma glucose level， body mass index and daily salt intake were different between different age groups， educational level and occupational types （P<0.05）. Systolic blood pressure， diastolic blood pressure， body mass index and daily salt intake were significantly different among high-risk groups with different marital status （P<0.05）. The daily salt intake and systolic blood pressure levels of high-risk population in different areas were significantly different （P<0.05）.

ConclusionWe should identify high-risk groups of hypertension as early as possible and actively carry out community health management and targeted lifestyle interventions. The focus should be on the groups and individuals with high-risk characteristics such as dietary high salt and overweight/obesity， male， middle-aged and low-educated groups. In this way， we can reduce the level of high-risk characteristics， prevent and delay the occurrence of hypertension.
