5 papers analyzed
These studies suggest that the average blood pressure for females varies by region, age, income, and body composition, with higher levels generally found in urban areas, low-income and middle-income countries, post-menopausal women, and those with higher BMI.

Average Blood Pressure for Females: A Comprehensive Analysis
Global Trends in Female Blood Pressure
Mean Systolic Blood Pressure (SBP) in Women
Globally, the average systolic blood pressure (SBP) for women has shown a slight decrease over the past few decades. In 2008, the age-standardized mean SBP for women worldwide was 124.4 mm Hg. By 2015, this figure had slightly decreased to 122.3 mm Hg. These trends indicate a modest decline in SBP among women globally, although regional variations exist. For instance, female SBP decreased significantly in Western Europe and Australasia by more than 3.5 mm Hg per decade. Conversely, regions such as Oceania, East Africa, and South and Southeast Asia experienced an increase in SBP for women, ranging from 1.0 to 2.7 mm Hg per decade.
Mean Diastolic Blood Pressure (DBP) in Women
The global age-standardized mean diastolic blood pressure (DBP) for women in 2015 was 76.7 mm Hg. This figure represents a slight decrease from previous decades, reflecting similar trends observed in SBP. The decrease in DBP was more pronounced in high-income regions, while some low-income and middle-income countries saw an increase or stabilization in DBP levels.
Regional Variations in Female Blood Pressure
Blood Pressure in South India
A study conducted in the North Arcot District of Tamilnadu State, South India, revealed significant differences in blood pressure between rural and urban women. The mean systolic blood pressure was 101.4 mm Hg for rural women and 105.3 mm Hg for urban women. Similarly, the mean diastolic blood pressure was 65.9 mm Hg for rural women and 68.0 mm Hg for urban women. These findings highlight the impact of urbanization on blood pressure levels among women in this region.
Blood Pressure in Adolescents
In a study of adolescents aged 10-18 years, the average systolic blood pressure for females ranged from 117.71 to 128.75 mm Hg, while the diastolic blood pressure ranged from 77.97 to 88.85 mm Hg. This study also found that blood pressure in adolescent females was significantly associated with weight, BMI, and waist circumference, indicating that anthropometric characteristics play a crucial role in determining blood pressure levels in this age group.
Gender Differences in Blood Pressure
Historically, women have exhibited lower blood pressure levels compared to men until the late forties, after which women's blood pressure tends to surpass that of men. For instance, a study analyzing blood pressure records from University of California freshmen and office patients found that the mean pressure for women was 10 mm Hg less than that for men until the late forties. This gender difference in blood pressure highlights the influence of hormonal and physiological changes that occur with aging.
Conclusion
In summary, the average blood pressure for females varies significantly across different regions and age groups. Globally, the mean systolic blood pressure for women is around 122.3 mm Hg, while the mean diastolic pressure is approximately 76.7 mm Hg. Regional studies, such as those conducted in South India, show variations between rural and urban populations. Additionally, adolescent females exhibit blood pressure levels influenced by anthropometric factors. Understanding these variations is crucial for developing targeted interventions to manage and reduce blood pressure-related health risks among women.
