Core Findings of the Meta-Analysis
A systematic review and meta-analysis published August 13 in the *American Journal of Cardiovascular Drugs* combined nine cohort studies tracking 480,479 adults aged 35–84 for a median of 14 years. Regular stair climbing was linked to a 39% lower risk of cardiovascular mortality and a 24% lower risk of death from any cause compared with infrequent stair use. The analysis also observed reduced incidence of heart attack, stroke and heart failure, though the exact magnitude varied across studies.
Study Design and Scope
The nine studies included healthy participants and individuals with prior heart attacks or peripheral artery disease; about 53 % of the pooled sample were female. Researchers measured stair use via self-reported daily flights, frequency of uninterrupted climbs, and occasional vigorous bouts, reflecting exposure in homes, workplaces and public buildings. A subset (five studies, 455,619 participants) provided the mortality risk ratios cited above.
Biological Rationale
Climbing a flight raises heart rate into the vigorous-intensity zone, similar to high-intensity interval training. Short bursts improve stroke volume, cardiac output and VO2peak, a strong predictor of mortality. These efforts also enhance endothelial function and lower LDL cholesterol, supporting the protective association.
Official Statements & Responses
Vassilios Vassiliou of the University of East Anglia’s Norwich Medical School emphasized that cardiovascular disease remains the world’s leading cause of death and that more than a quarter of adults globally fail to meet activity guidelines. He suggested promoting stair use in workplaces and public spaces as part of a broader strategy.
Sophie Paddock, also at UEA, noted that modest increases in stair climbing produced measurable health benefits and should be integrated into daily routines, while cautioning that stair climbing may not suit individuals with mobility limitations or unstable cardiovascular conditions.
Conflicting Reports & Gaps
Earlier investigations produced mixed results. The Harvard Alumni Health Study reported an all-cause mortality benefit but no significant reduction in cardiovascular deaths. A UK Biobank analysis of at-home stair use found benefits for all-cause and cancer mortality but not for cardiovascular mortality. The meta-analysis attributes these discrepancies to narrower exposure definitions and potential residual confounding—regular stair users may differ in diet, overall activity, socioeconomic status and other factors. Most underlying studies relied on self-reported stair use; validation studies show only a fair correlation with objective wearable measurements. The authors call for trials employing accelerometers to refine dose-response relationships and confirm causality.

- “Cardiovascular disease is the leading cause of death worldwide — with cases nearly doubling between 1990 and 2019,” — Vassilios Vassiliou
- “Even brief bursts of physical activity have beneficial health impacts, and short bouts of stair climbing should be an achievable target to integrate into daily routines,” — Sophie Paddock
What’s Next
The authors recommend further research using wearable accelerometers to establish an optimal “dose” of stair climbing and to assess its effects in younger and older populations not covered by the current analysis. They also suggest evaluating implementation strategies that encourage stair use in public and occupational settings.
