OBJECTIVETo assess the cardiovascular disease-related risk levels among hypertensive people in Zhejiang.

METHODSSubjects were selected from local residents aged ≥18 years old, using the multi stage stratified-random sampling method. All participants accepted physical examinations including blood tests for lipids, fasting blood glucose, 2 hours blood glucose and physical measurements for obesity and blood pressure in the year 2010.

RESULTSTotally, 17 437 subjects were finally included in the study, in which 5 227 were diagnosed as having hypertension, with 'grade one hypertension' the majority. Cardiovascular disease-related risk factors would include older age (male >55 years, female >65 years), smoking, abnormal fasting glucose, impaired glucose tolerance, abnormal TC, abnormal HDL-C, abdominal obesity and obesity, with rates as 42.78% , 20.89%, 5.31%, 8.35%, 9.87%, 35.66%, 40.55% and 13.93%. Most of the hypertensive people had two (30.44%) or three risk factors (29.96%). Proportions of low, medium, high or very high risks were 9.70% , 47.71% , 18.81% and 23.78% , respectively in those people with hypertension. Significant differences on cardiovascular risk stratification were found between age groups, sex and regions. There were also statistically significant differences noticed, regarding the levels of cardiovascular disease related risks between in patients aware or unaware of the diseases, under control or uncontrolled of the situation.

CONCLUSIONPeople under high risk or very high risk on cardiovascular disease did exist in Zhejiang, especially in those 60-year-olds, males and urban residents.
