The Claim
In older adults aged 65 and above, resting systolic blood pressure below 115 mmHg and diastolic blood pressure below 68 mmHg are associated with an increased risk of falls.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Older adults with low resting blood pressure—below 115/68 mmHg—have a higher rate of falls compared to those with higher blood pressure.
See the scientific wording
In older adults aged 65 and above, a lower resting systolic blood pressure (below 115 mmHg) and diastolic blood pressure (below 68 mmHg) are associated with an increased risk of falls, as observed in a cohort of 30 individuals where fallers had significantly lower baseline blood pressure compared to non-fallers (p = 0.004 for systolic, p = 0.018 for diastolic). This association suggests that hypotension may contribute to postural instability, though confounding factors such as medication use or frailty were not fully controlled.
When a person stands up, blood pools in the legs, lowering blood pressure. The body normally responds by tightening blood vessels and increasing heart rate to keep blood flowing to the brain. In older adults with low resting blood pressure, this response is too slow or too weak, so the brain doesn't get enough blood for a few seconds. This causes dizziness and loss of balance, leading to a fall.
What the research says
1 studyOlder adults who had fallen before tended to have lower blood pressure when sitting or lying down than those who hadn’t fallen, and this was a clear, measurable difference in the study.
