The relationship between daily step count and all-cause mortality – umbrella review

<ns3:p>Background: This umbrella review assesses the relationship between daily step count and all-cause mortality. The aim is to approximate the ideal number of steps per day and provide insights into improving public health. Methods: The inclusion criteria focused on studies analyzing daily step count and health outcomes, specifically mortality. Databases searched included PubMed and Scopus from January 2020 to December 2024. Search terms included “daily steps,” “mortality,” and “health.” Risk of bias was assessed using PEDro scale. Results: Of 389 articles, 17 met the inclusion criteria, encompassing over 200,000 participants. An increase in daily step count was consistently associated with reduced all-cause mortality. Significant benefits were observed with 8,000–10,000 steps per day. The review highlighted variations in participant characteristics, step measurement methods, and geographic distribution. Discussion: The evidence has limitations, such as differences in how steps were measured, variations in participant groups, and study locations, which may affect the results. Some studies also lacked consistent reporting, leading to potential bias. Future research should address these gaps to strengthen the overall findings.</ns3:p>
