Normal Blood Pressure Ranges in Women
Normal blood pressure in women is generally defined as a systolic blood pressure (SBP) less than 130 mmHg and a diastolic blood pressure (DBP) less than 85 mmHg. Specifically, normal blood pressure is often considered to be in the range of 120-129 mmHg systolic and 75-84 mmHg diastolic for women Conen2007Kringeland2020Kringeland2021. Blood pressure readings above these values but below the threshold for hypertension (140/90 mmHg) are classified as "high-normal" blood pressure, which is 130-139 mmHg systolic and 85-89 mmHg diastolic Conen2007Ohldieck2023Kringeland2020+2 MORE.
Cardiovascular Risk and Blood Pressure Categories in Women
Women with normal blood pressure (120-129/75-84 mmHg) have a lower risk of major cardiovascular events compared to those with high-normal blood pressure (130-139/85-89 mmHg) or hypertension (≥140/90 mmHg) Conen2007Kringeland2020Kringeland2021. Studies show that even high-normal blood pressure in women is associated with a higher risk of developing cardiovascular disease and acute coronary syndromes compared to men with similar blood pressure levels Conen2007Kringeland2020Kringeland2021. This suggests that women may be more sensitive to increases in blood pressure within the high-normal range.
Progression to Hypertension in Women
High-normal blood pressure in midlife is a particularly strong predictor for the development of hypertension later in life for women, even more so than for men Ohldieck2023Ohldieck2022. Women with high-normal systolic blood pressure in early midlife are at greater risk of progressing to hypertension compared to men, highlighting the importance of early detection and intervention in women Ohldieck2023Ohldieck2022.
Prevalence and Trends of Blood Pressure in Women
Recent data from the United States show that the prevalence of both hypertension and high-normal blood pressure is lower in women compared to men . However, the risk associated with high-normal blood pressure is greater in women, especially regarding the development of cardiovascular disease and hypertension over time Conen2007Kringeland2020Ohldieck2022+2 MORE.
Optimal Diastolic Blood Pressure in Older Women
For older women, both low and high diastolic blood pressure are associated with increased mortality risk. The lowest risk of death is observed with a diastolic blood pressure between 68 and 75 mmHg, with a nadir at 72 mmHg . This suggests that maintaining diastolic blood pressure within this range may be optimal for older women.
Age and Sex Differences in Blood Pressure
Historically, women have lower average blood pressure than men until their late forties, after which women's blood pressure tends to rise and may surpass that of men . This age-related change highlights the importance of monitoring blood pressure in women as they age.
Conclusion
Normal blood pressure in women is defined as systolic less than 130 mmHg and diastolic less than 85 mmHg, with optimal diastolic pressure in older women between 68 and 75 mmHg. High-normal blood pressure poses a greater risk for cardiovascular disease and progression to hypertension in women than in men, emphasizing the need for careful monitoring and early intervention in women, especially as they age.
