Aim To investigate the current prevalence of high-normal blood pressure,hypertension and their related risk factors of officials in Changsha city Hunan Province,and to provide evidences for making strategies of prevention and treatment. Methods A resident group of officials in Changsha city was selected for a cross-sectional investigation.The subjects were classified as three groups: people with normal blood pressure,high-normal blood pressure and hypertension.The prevalence of high-normal blood pressure and hypertension in the selected subjects was calculated.And the differences of smoking,drinking,and other risk factors were compared among the three groups,and multinomial Logistic regression analysis was applied to analyze the related risk factors.Moreover,conditions that the three groups were accompanied with possible risk factors were concluded. Results The prevalence of high-normal blood pressure was 42.54% and that of hypertension was 22.87% in officials in Changsha city.A much larger percentage of people with high-normal blood pressure had a habit of smoking or drinking,or a family history of premature cardiovascular disease than normal people,but the percentage was much smaller than people with hypertension(P<0.05).People with high-normal blood pressure had higher levels of body mass index(BMI),fasting blood glucose(FBS),total cholesterol(TC),low density lipoprotein cholesterol(LDLC),triglyceride(TG) than normal people(P<0.05),but lower levels than people with hypertension(P<0.05).The level of high density lipoprotein cholesterol(HDLC) was lower than normal group(P<0.05) but higher than hypertension group(P<0.05).The prevalence of normal-high blood pressure in men was much higher than that in women(P<0.01),but there was no significant difference in the prevalence of hypertension(P>0.05) between men and women.The age,BMI,smoking,drinking,family history of premature cardiovascular disease,lipid abnormality and blood sugar were highly related to the prevalence of high-normal blood pressure and hypertension.12.94% of people with high-normal blood pressure and 14.02% of people with hypertension had three or more cardiovascular risk factors. Conclusion The prevalence of high-normal blood pressure and hypertension was higher in officials in Changsha city Hunan Province than national average level.High normal blood pressure was more common in men than in women.Factors as age,smoking,drinking,family history,blood fat,blood sugar,BMI were highly related to the prevalence of high-normal blood pressure and hypertension.Three or more cardiovascular risk factors existed in more than 10% of people with high-normal blood pressure or hypertension.
