title: Alcohol dependence and risk of somatic diseases and mortality: a cohort study in 19 002 men and women attending alcohol treatment.
abstract: OBJECTIVE
  To (1) estimate sex-specific risks of a comprehensive spectrum of somatic diseases in alcohol-dependent individuals versus a control population, and in the same population to (2) estimate sex-specific risks of dying from the examined somatic diseases.
  
  
  METHODS
  Register-based matched cohort study. Alcohol-dependent individuals were identified from the Copenhagen Alcohol Cohort. Controls were selected randomly from the Danish Civil Registration System. Information on somatic diseases was obtained from the Danish National Patient Registry and causes of death obtained from the Cause of Death Registry. Cox proportional hazards model was applied to estimate hazard ratios (HRs).
  
  
  METHODS
  Denmark.
  
  
  METHODS
  A total of 19 002 alcohol-dependent individuals and 186 767 controls.
  
  
  METHODS
  Outcome variables included 11 disease groups and 29 subgroups, defined according to the International Classification of Diseases (ICD). The main predictor variable was diagnosis of alcohol dependence according to ICD.
  
  
  RESULTS
  Alcohol-dependent men and women compared with controls had statistically significantly higher risks of all disease groups and the majority of subgroups when analysed as disease events. HRs were elevated for well-established alcohol-related diseases but also for diseases such as dementia [men, HR = 2.0, 95% confidence interval (CI) = 1.6-2.3; women, HR = 2.4, 95% CI = 1.8-3.2], psoriasis (men, HR = 4.3, 95% CI = 3.5-5.2; women, HR = 5.4, 95% CI = 3.7-7.8) and breast cancer in men (HR = 3.3, 95% CI = 1.6-7.0). Similar results were found when disease groups and subgroups were analysed as causes of death.
  
  
  CONCLUSIONS
  Alcohol-dependent men and women have significantly higher risks of a comprehensive spectrum of somatic diseases, both as disease events and as causes of death, relative to individuals from the general population.
