Abstract

The prevalence of night eating syndrome (NES) was 17.4% among patients with bipolar disorder (BD).

  • Patients with BD experiencing NES reported poorer sleep quality compared to those without NES.
  • Greater seasonality was observed in BD patients who had NES.
  • Lower scores on the Morningness-Eveningness Questionnaire were associated with NES in BD patients.
  • Chronotype indirectly affected night eating symptoms through sleep quality in BD patients.
  • Direct effects of seasonality on night eating symptoms were identified in bipolar disorder.
