Understanding 118/70 Blood Pressure: Normotensive Insights and Global Estimates
Normal Ambulatory Blood Pressure Ranges
Blood pressure (BP) is a critical indicator of cardiovascular health, and understanding what constitutes a "normal" range is essential for both clinical practice and personal health monitoring. A comprehensive meta-analysis of 23 studies involving 3,476 normotensive subjects provides valuable insights into the mean and range of normal ambulatory BP. The findings indicate that the average 24-hour BP for healthy individuals is approximately 118/72 mm Hg, with daytime BP averaging 123/76 mm Hg and nighttime BP averaging 106/64 mm Hg. These values serve as a reference for what is considered normal BP in a healthy population.
Blood Pressure in Children
Blood pressure norms can vary significantly with age, especially in children. The Ewha Birth and Growth Cohort Study developed BP reference values for non-overweight children aged 3-9 years. For boys and girls aged 9 years, the 90th percentile of systolic/diastolic BP was found to be 118/70 mm Hg and 116/70 mm Hg, respectively. This indicates that a BP of 118/70 mm Hg is within the higher range of normal for children in this age group, suggesting that it is a healthy BP level for young individuals.
Global Blood Pressure Estimates
Global estimates of BP levels by age and sex reveal significant variations across different regions. Data from over 230 surveys involving more than 660,000 participants show that mean systolic BP (SBP) values range from 114 to 164 mm Hg for females and 117 to 153 mm Hg for males, with SBP levels generally increasing with age. These findings highlight the importance of considering regional and demographic factors when assessing BP levels.
Ambulatory Blood Pressure in Adults
The Allied Irish Bank Study, which investigated 815 healthy bank employees aged 17-79 years, found that the average 24-hour ambulatory BP was 118/72 mm Hg, closely aligning with the meta-analysis findings. Daytime BP averaged 124/78 mm Hg, while nighttime BP averaged 106/61 mm Hg. These values further support the notion that a BP of 118/70 mm Hg falls within the normal range for healthy adults.
Conclusion
A blood pressure reading of 118/70 mm Hg is generally considered normal and healthy for both adults and children, based on extensive research and global estimates. This BP level aligns well with the average values found in multiple studies, indicating it is within the expected range for normotensive individuals. Understanding these norms can help in the early detection and management of potential cardiovascular issues.
