Systolic Blood Pressure: Males, Age 20-29
Systolic blood pressure is the 'upper number', the peak pressure in your arteries when the heart contracts. The American Heart Association defines normal systolic BP as below 120 mmHg. Data are from NHANES 2001-2008 (n=19,921), a nationally representative survey of US adults. Age-standardized mean systolic BP in the US is above the global median (NCD-RisC, Lancet 2021), so upper percentiles may not generalize to all populations.
Percentile Distribution (mmHg)
| Percentile | Value (mmHg) | Rating |
|---|---|---|
| 5th | 100 | Excellent |
| 25th | 110 | Above average |
| 50th | 118 | Average |
| 75th | 126 | Below average |
| 95th | 140 | Poor |
What these numbers mean for males aged 20-29
A score around 118 mmHg is typical (50th percentile) for males in this age group. Times below about 110 mmHg fall near the 75th percentile or higher, indicating above-average performance (faster is better). Times above about 126 mmHg fall near the 25th percentile; about 75% of the reference population ran faster.
Percentiles show how common a value is, not whether it is healthy.
