title: "Exercise dependence"--a problem or natural result of high activity?
abstract: OBJECTIVE
  To compare physical activity (PA) and exercise dependence (ED) in 267 weight-loss maintainers (WLM) and 213 normal-weight (NW) controls.
  
  
  METHODS
  PA and ED assessed via accelerometery and the Exercise Dependence Questionnaire.
  
  
  RESULTS
  WLM had higher  PA levels and ED scores than those of NW (P< 0.0001). WLM status (P=.006) and higher PA (P=.0001) were independently related to higher ED, although effect sizes were larger for PA. Exercising for weight control was the ED domain that most discriminated WLM from NW.
  
  
  CONCLUSIONS
  WLM  have higher ED scores than do NW, but this is mostly due to exercising for weight control.
