• Description:
  Objective.
  
  Adults with foot symptoms (i.e., pain, aching, or stiffness) may be at increased risk of reduced time to all-cause mortality. The purpose of this study was to evaluate whether foot symptoms are independently associated with all-cause mortality in older adults.
  
  Methods.
  
  We analyzed longitudinal data from 2613 participants from the Johnston County Osteoarthritis Project (JoCoOA), a longitudinal population-based cohort of adults 45 years of age and older. Participants completed questionnaires at baseline to determine presence of foot symptoms and covariable status. Baseline walking speed was measured via an 8-foot walk test. To examine the association of foot symptoms with time to mortality, hazard ratios (HR) and 95% confidence intervals (CI) were calculated using Cox regression models, adjusted for potential confounders.
  
  Results.
  
  We observed 813 deaths over 4 to 14.5 years of follow-up. At baseline, 37% of participants had foot symptoms, mean age was 63 years, mean BMI was approximately 31 kg/m2, 65% were women, and 33% were Black. Moderate to severe foot symptoms were associated with reduced time to mortality after adjustment for demographics, comorbidities, physical activity, and knee and hip symptoms (HR=1.30, 95%CI=1.09–1.54). Importantly, this association was not modified by walking speed or diabetes
  
  Conclusion.
  
  Individuals with foot symptoms had an increased hazard of all-cause mortality compared to those with no foot symptoms. These effects were independent of key confounders and were not moderated by walking speed. Effective interventions to identify and manage at least moderate foot symptoms may reduce the risk of decreased time to mortality.
