title: Sleep problems are associated with binge eating in women.
abstract: OBJECTIVE
  We examined the association among current self-reported sleep problems, lifetime binge eating (BE), and current obesity in women from the Swedish Twin study of Adults: Genes and Environment.
  
  
  METHODS
  Logistic regression analyses were used to evaluate these associations in 3,790 women aged 20-47 years.
  
  
  RESULTS
  BE was reported by 244 (6.4%) women and was positively associated with not getting enough sleep (p < .015), sleeping poorly (p < .001), problems falling asleep (p < .001), feeling sleepy during work or free time (p < .001), and disturbed sleep (p < .001). These same sleep variables, as well as napping and being a night person, were also significantly associated with obesity. The associations between BE and sleep remained after accounting for obesity.
  
  
  CONCLUSIONS
  This investigation offers empirical support for an independent association between sleep problems and BE, which is likely due to complex psychological, biological, neuroendocrine, and metabolic factors.
