OBJECTIVES: 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.
