title: Nonprescription use of pain relievers by middle-aged and elderly community-living adults: National Survey on Drug Use and Health.
abstract: OBJECTIVE
  To estimate the frequency, distribution, and correlates of nonprescription use of pain relievers by middle-aged and elderly persons in the United States.
  
  
  METHODS
  Cross-sectional data analysis of a national community survey.
  
  
  METHODS
  The 2005 and 2006 National Surveys on Drug Use and Health.
  
  
  METHODS
  Ten thousand nine hundred fifty-three respondents aged 50 and older (6,717 aged 50-64 and 4,236 aged > or = 65).
  
  
  METHODS
  Social and demographic variables, detailed assessment of nonprescription use (and abuse) of prescription pain relievers (e.g., acetaminophen with codeine, morphine), substance use, major depression, self-reported medical illnesses, and self-rated health.
  
  
  RESULTS
  A small proportion of the sample (1.4%) reported nonprescription use of prescription pain relievers during the previous year. Combinations of acetaminophen and hydrocodone or propoxyphene were the most commonly used drugs. Use was associated with younger age (odds ratio (OR)=2.39, 95% confidence interval (CI)=1.31-4.36), American Indian and Alaska native (OR=8.78, 95% CI=2.50-30.85), and use of marijuana (OR=7.07, 95% CI=3.99-12.53). Fewer than 10% of nonprescription users were abusing these medications or dependent upon them.
  
  
  CONCLUSIONS
  In a representative sample of middle-aged and older adults, nonprescription use of prescription pain relievers is relatively uncommon, but the much higher use by middle-aged adults suggests that, as this cohort ages, the problem may increase in elderly people.
