The Claim

In community-dwelling older adults with hypertension, intensive blood pressure control (<130/70 mmHg) is associated with a 30% lower risk of falls or fractures among individuals classified as non-frail by the Frailty Phenotype, but not among those classified as non-frail by the Clinical Frailty Scale.

In plain English

Among older adults with high blood pressure, strictly lowering blood pressure to below 130/70 mmHg is linked to a 30% reduction in falls or fractures for those deemed non-frail using the Frailty Phenotype criteria, but not for those deemed non-frail using the Clinical Frailty Scale.

See the scientific wording

In community-dwelling older adults with hypertension, intensive blood pressure control (<130/70 mmHg) is associated with a 30% lower risk of falls or fractures among those classified as non-frail by the Frailty Phenotype, but no such protective effect is observed in those classified as non-frail by the Clinical Frailty Scale.

Why this might work

When older adults have weak muscles and low physical activity, their muscles cannot push blood back to the heart well when they stand up. If their blood pressure is lowered too much, their blood pressure drops even further when standing, causing dizziness and loss of balance. This leads to falls and broken bones. People with other health problems or disabilities fall for different reasons, like poor balance or confusion, and lowering their blood pressure does not make their falls worse or better.

    In older adults with high blood pressure who are physically strong (as measured by the Frailty Phenotype), lowering blood pressure more aggressively helped prevent falls and broken bones — but this benefit didn’t show up in people considered strong based on clinical symptoms (Clinical Frailty Scale).
