Older women who walk about 4,400 steps a day tend to live longer than those who walk only 2,700 steps. More walking is linked to lower risk of dying from any cause.

The association between daily step count and all-cause and cardiovascular mortality: a meta-analysis.
The study found that walking more steps each day is linked to a lower risk of dying from any cause, especially when going from about 2,700 to over 4,000 steps a day, which supports the claim.
Association of Step Volume and Intensity With All-Cause Mortality in Older Women.
The study found that older women who walked about 4,400 steps a day had much lower chances of dying during the study than those who walked about 2,700 steps, which matches the claim.
The study shows that older women who walk more steps each day have a lower risk of dying from any cause, and the biggest benefits happen up to about 5,000–6,000 steps a day. This generally supports the idea that walking more helps, even if the exact number in the claim is a bit lower.

The relationship between daily step count and all-cause mortality – umbrella review
The study says walking 8,000 to 10,000 steps a day is best for living longer, but the claim says 4,400 steps is enough — especially for older women. That doesn’t match.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
