Walking About 100 Minutes a Day Linked to Lower Risk of Chronic Low Back Pain, Study Finds

Using weeklong sensor data from more than 11,000 adults, researchers found walking time predicted risk more strongly than intensity.

Overview

  • People exceeding 100 minutes of daily walking had roughly a 23% lower risk of developing chronic low back pain than those walking under 78 minutes, with 78–100 minutes linked to a 13% reduction.
  • The prospective cohort study from NTNU, published in JAMA Network Open, followed 11,194 adults free of chronic low back pain at baseline over an average of 4.2 years.
  • Participants wore accelerometers on the thigh and back for about 5.7 days to capture walking volume and intensity, and approximately 15% reported chronic low back pain during follow-up.
  • Walking volume showed a stronger association with reduced risk than intensity, and higher intensity added little benefit for those already walking more than about 125 minutes daily.
  • The association was more consistent in adults 65 and older and similar across sexes, and authors cautioned that observational design, single baseline measurement, and residual confounding limit causal conclusions.
