Annual 1\u2010week accelerometer trials were used to estimate steps. VF results from both eyes were merged to determine integrated VF sensitivity, with lower sensitivity indicating greater VF damage. Other potential risk factors for falls (age, sex, race, comorbid illness, polypharmacy) were determined using questionnaires.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The cumulative probability of falls was 45.2% at 12 months and 61.6% at 24 months; cumulative probability of injurious falls was 23.3% at 12 months and 40.0% at 24 months. Greater VF damage was associated with higher rates of falls\/steps (incident rate ratio = 1.40\/5 dB decrement in sensitivity; p = .004) but not with more falls\/year (incident rate ratio = 1.25\/5 dB decrement in sensitivity; p = .07). Several additional variables (older age, female sex, more comorbid disease) were also associated with a higher rate of falls\/step (p &lt; .02 for all) but not with falls\/year (p &gt; 0.10). Black participants had fewer falls\/year than whites (p = .002) but did not differ in falls\/step (p = .07). Similar results were obtained when injurious falls were analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>\n                      Risk factors associated with frequent falls when walking (falls\/step) are not properly identified when analyzing falls as a rate over time (falls\/year).
