Abstract: Objective　To investigate the diagnostic criteria for hypertension in women and understand their normal blood pressure level by comparing the gender differences in blood pressure.Methods　Women at the age of 18-20，21-30，31-40，41-50，51-60，and over 61 years from five villages in Suzhou，Anhui Province，who voluntarily went to the local clinic for examination were selected from May to December 2016，each age group with 150 cases via convenient sampling methods.The same number of male adults of the same age range in each village were enrolled by using the same sampling method and screening criteria.Blood pressure was measured by using a bench-top mercury sphygmomanometer，ventricular septal and/or left posterior wall thickening measured by echocardiography，and left ventricular high voltage and/or left axis deviation measured by electrocardiogram.Results　Except for 51-60 years group，the SBP and DBP of women were significantly lower than that of men （P<0.05）.The proportion of women in 18-20 years，21-30 years，31-40 years groups whose blood pressure were <90/60 mm Hg （1 mm Hg=0.133 kPa）was higher than that of men （P<0.05）.In people whose blood pressure were <90/60 mm Hg，SBP and DBP of female were （85.6±2.4） mm Hg，（55.4±1.0） mm Hg，and SBP and DBP of male were （87.9
±2.4） mm Hg，（58.7±0.7） mm Hg，respectively，and there was a statistically significant difference （t=-2.947，-10.694，P<0.05）.There was no significant difference in the ratio of people whose blood pressure were ≥140/90 mm Hg，120-139/80-89 mm Hg between men and women in all age groups （P>0.05）.In women with blood pressure of 120-139/80-89 mm Hg，incidence of symptoms such as headache，dizziness，palpitation，chest tightness，ventricular septal and/or left posterior wall thickening，and left ventricular high voltage and/or left axis deviation were higher than those of men （P<0.05）.Conclusion　There may be differences in normal blood pressure level and diagnostic criteria for hypertension in different gender.Normal blood pressure level in women maybe lower than that in men.Normal SBP and DBP in women may be 85-120 mm Hg，55-80 mm Hg，respectively.Female whose blood pressure are higher than 120/80 mm Hg may have hypertension.
