title: Muscle strengthening activities and mortality with considerations by hearing sensitivity.
abstract: OBJECTIVE
  Research demonstrates that hearing impairment is associated with premature all-cause mortality. Emerging work indicates that physical activity is associated with hearing sensitivity and muscle strengthening activities (MSA) are favorably associated mortality in the general population. Whether MSA can promote survival among those with hearing impairment is, at this point, unknown, which was this study's objective.
  
  
  METHODS
  Prospective cohort study using data from the 2003-2006 National Health and Nutrition Examination Survey, with follow-up through 2011.
  
  
  METHODS
  1482 adult (20-85 years) participants comprised the analytic sample.
  
  
  RESULTS
  Among the study participants, 152 died over the follow-up period (10.26%; unweighted); the unweighted median follow-up period was 89 months (IQR = 74-98 months). Among adults with moderate or greater hearing loss who achieved the United States Department of Health and Human Services guidelines for MSA (2 + sessions/week), they were at a 71% reduced risk of all-cause mortality (HRadjusted = 0.29; 95% CI: 0.10-0.83; P = 0.02).
  
  
  CONCLUSIONS
  MSA may help to prolong survival among those with worse hearing impairment.
