Overview

  • Fast walking for at least 15 minutes daily was linked to a 19–20% lower risk of death from any cause in the study population.
  • The protective effect was strongest for cardiovascular-related deaths and remained significant after adjusting for lifestyle factors like diet and smoking.
  • By contrast, more than three hours of slow walking per day yielded only a modest 4% reduction in mortality, underscoring the impact of walking intensity over duration.
  • Investigators used self-reported data from 79,856 predominantly low-income Black US adults across 12 southeastern states to assess walking habits and mortality outcomes.
  • Lead researchers urge tailored public health campaigns and community programs to promote brisk walking as an accessible strategy to reduce health inequities.
