title: Physical activity and alcohol use disorders.
abstract: BACKGROUND
  Prior research has documented a counterintuitive positive association between physical activity and indices of alcohol consumption frequency and heaviness.
  
  
  OBJECTIVE
  To investigate whether this relation extends to alcohol use disorder and clarify whether this association is non-linear.
  
  
  METHODS
  This is a cross-sectional, correlational population-based study of US adults (N = 34,653). The Alcohol Use Disorder and Associated Disabilities Interview Schedule was used to classify past-year DSM-IV alcohol use disorder and self-reported federal government-recommended weekly physical activity cutoffs.
  
  
  RESULTS
  After statistically controlling for confounds, alcohol abuse but not dependence was associated with greater prevalence of physical activity. Number of alcohol use disorder symptoms exhibited a curvilinear relationship with meeting physical activity requirements, such that the positive association degraded with high symptom counts.
  
  
  CONCLUSIONS
  There is a positive association between physical activity and less severe forms of alcohol use disorder in US adults. More severe forms of alcohol use disorder are not associated with physical activity.
