Association between frequency of meeting daily step thresholds and all-cause mortality and cardiovascular disease in older women
Published 2025Reviewer Insight11/7/2025This study only tracked women's walking for one week, which may not reflect their usual habits. The results showed confusing patterns—in one analysis, walking more than 6,000 steps appeared riskier. This raises doubts about the reliability of the 4,000-step recommendation. Since this is an observational study, we also can't validate the number of steps actually lower disease risk.
