Objective: The current study was conducted in order to assess sleep-wake cycles among obese (OB) adolescents with/and without binge eating behavior as compared to normal-weight (NW) control group. Method: The OB group consisted of 32 adolescents (age range 12-18). All participants received a diagnosis of primary obesity. The OB group was subdivided into two groups: obese with binge eating (OB-BE) and obese without binge eating (OB-non-BE). The OB-BE diagnosis was made in accordance with partial criteria of DSM-IV for binge eating disorder (BED). A NW control group comprised 12 adolescents. Sleep-wake cycles were monitored for 1 week, using mini-actigraphs and self-report questionnaires. Results: Actigraphic monitoring revealed no significant differences in objective and subjective sleep-wake cycles between groups. Forty-eight percent of the obese adolescents reported uncontrolled binge eating episodes. Discussion: The results were discussed in light of the contrast to previous results, which indicated that sleep disturbances among adolescents were not directly related to obesity, but rather to physical activity level.
