title: Modifiable risks of incident functional dependence in Hispanic and non-Hispanic white elders: the San Luis Valley Health and Aging Study.
abstract: OBJECTIVE
  This study identified modifiable risks associated with incident functional dependence, compared their effects, and estimated the percent risk attributable to each factor, by ethnicity.
  
  
  METHODS
  The prospective study cohort comprised 751 rural Hispanic and non-Hispanic White elders from southern Colorado who reported no dependence in basic and instrumental activities of daily living (ADLs and IADLs) at baseline. Logistic regression modeled the effects of physical inactivity, nutritional risk, smoking, and falls on incident disability 22 months later, with and without adjustment for baseline ADL and IADL difficulty. Population attributable risk percentages assessed these modifiable risks by ethnicity.
  
  
  RESULTS
  Each risk factor multiplied the likelihood of incident dependence by 1.4 or more, adjusted for covariates. Attributable risk percentages ranged from 8% to 32% depending on risk factor, ethnicity, and baseline ADL and IADL difficulty status. Attributable risk was generally greater among Hispanic elders, the result of higher prevalence of most of the risk factors.
  
  
  CONCLUSIONS
  Interventions targeted at inadequate nutrition, inactivity, smoking, and preventable falls offer opportunities to reduce incident functional disability, especially among Hispanic elders.
