Stair climbing data was collected through touchscreen questionnaire. The primary outcome was new-onset VHD, which was defined using ICD-10 code. Incident VHD was followed till March 1st, 2022. Cox models were used to assess the association between stair climbing and VHD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 488,964 participants (mean age 56.5 years) were included in the present study. During a median follow-up time of 13.0 years, 17,494 (3.6%) participants experienced new-onset VHD. After adjustments, climbing 10\u201350, 60\u2013100, 110\u2013150 and \u2265160 steps of stairs per day were associated with significant reduced VHD risks of 12%, 15%, 22%, and 20%, respectively (\n                      <jats:italic>P<\/jats:italic>\n                      for trend &amp;lt;0.0001), compared to not climbing any stairs. For VHD subtypes, individuals who climbed more than 160 steps per day exhibited a lowered risk of rheumatic valve disease (Hazard ratio: 0.79, 95% confidence intervals: 0.66\u20130.95), non-rheumatic valve disease (0.78, 0.72\u20130.83), multiple valve disease 0.82, 0.74\u20130.90), and endocarditis (0.63, 0.48\u20130.83). Such associations were more evident among participants with lower levels of total physical activity.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In this large population-based cohort study, the number of climbed stairs was independently associated with decreased risk of new-onset VHD.
