Nocturnal eating is common among obese patients prior to bariatric surgery. Little is known about the relationship between nocturnal eating, eating-related and general psychopathology, and health-related quality of life (HRQOL). A group of 148 obese patients (mean BMI 49.3, SD 7.8) prior to bariatric surgery were investigated. We compared patients who reported nocturnal eating at least once in the last 4 weeks with patients without nocturnal eating episodes. Patients completed a battery of questionnaires assessing eating related and general psychopathology and quality of life. Twenty-nine (19.6%) patients reported nocturnal eating (eating after waking up at night) during the last 28 nights, men and women did not differ in frequency of nocturnal eating. Patients with nocturnal eating reported a significantly higher BMI (kg/m(2)), more feelings of hunger, and significantly more impairment in the mental aspects of HRQOL. The other measures of HRQOL showed only minor differences. Measures of general psychopathology (depression and anxiety) also differed significantly with nocturnal eating patients reporting significantly more impairment. Binge eating disorder and nocturnal eating showed no association.
[Show abstract][Hide abstract] ABSTRACT: The aim of the study was to explore the nature and extent of the association between night eating, other forms of disordered eating and obstructive sleep apnea (OSAS).Eighty-one participants (20 women and 61 men), mean age 53.7 years diagnosed with OSAS were assessed prior to starting treatment. Using a cut-off of > or =25 on the Night Eating Questionnaire (NEQ), 8.6% of the participants screened positive for night eating syndrome (NES). In addition, 7.5% met criteria for a daytime eating disorder. NES was significantly associated with diagnoses of depression, anxiety and eating disorders and was significantly correlated with an impairment of mental quality of life. No associations were found between NES and gender, BMI and the severity of the OSAS. NES does not appear to be closely linked to OSAS; however, in patients with OSAS and NES a significant co-morbidity with psychiatric disorders can be expected which might require additional treatment.
[Show abstract][Hide abstract] ABSTRACT: To review the empirical literature for evidence in support of inclusion of Night Eating Syndrome (NES) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders.
Based on a literature search using PubMed, 47 empirical studies of NES were identified.
The literature reflects use of varying definitions; progress has been made toward reliable measurement of night eating symptoms; evidence regarding a differentiation of NES from "normalcy" or from other eating disorders is based largely on samples of convenience; only one controlled treatment study has been published.
There are limited data supporting the clinical utility and validity of NES; several options regarding the inclusion of NES in DSM-V are discussed.

[Show abstract][Hide abstract] ABSTRACT: To examine clinical correlates of nocturnal eating, a core behavioral symptom of night eating syndrome.
Data from 285 women who had participated in a two-stage screening for binge eating were utilized. Women (n = 41) who reported one or more nocturnal eating episodes in the past 28 days on the eating disorder examination and women who did not report nocturnal eating (n = 244) were compared on eating disorder symptomatology, body mass index (BMI), and on measures of psychosocial adjustment.
Nocturnal eaters were significantly more likely to report binge eating and differed significantly from non-nocturnal eaters (with responses indicating greater disturbance) on weight and shape concern, eating concern, self-esteem, depression, and functional impairment, but not on BMI or dietary restraint. Group differences remained significant in analyses adjusting for binge eating.
This study confirms the association between nocturnal eating and binge eating previously found in treatment seeking samples yet also suggests that the elevated eating disorder symptoms and decreased psychosocial adjustment observed in nocturnal eaters is not simply a function of binge eating.
