the nature of Night Eating Syndrome using network analysis to understand unique symptomological relationships
International Journal of Eating Disorders, 2021Co-Authors: Marshall T Beauchamp, K. C. Allison, J. D. LundgrenAbstract:Objectives Despite the initial characterization of Night Eating Syndrome (NES) in 1955, the definition and operationalization of its symptoms has varied considerably. To standardize the definition of NES and its symptoms, Allison et al. developed research diagnostic criteria. Even so, conceptualization and intervention of NES remains guided by medical models, which assume that pathology is driven by a distinct, underlying causal mechanism. Conversely, recent work on other Eating disorders (EDs) has used network analysis to reconceptualize ED psychopathology and treatment by identifying (a) unique relationships between key symptoms, and (b) the symptoms most central to specific EDs. The present study examined NES symptoms through network analysis to identify the most central symptoms within the NES network. Method Regularized partial correlation networks were estimated using 144 individuals in a community sample diagnosed with NES. Participants completed semi-structured interviews, self-report measures, and food/sleep diaries to measure NES symptoms, nonspecific health domains (e.g., sleep disturbance, overall mood, stress, and circadian rhythm functioning), and transdiagnostic ED symptoms. Results Depressed mood, poor sleep quality, and a strong urge to eat upon awakening at Night were highly central to the psychopathology network for NES and were significantly more central than most other NES symptoms and nonspecific health domains. Discussion This study provides insight on the unique symptomological relationships of NES and sets the stage for future work that can identify causal linkages among NES symptoms. These symptoms represent key elements of the core psychopathology of NES and should represent primary targets for intervention.

a review of the relationship between Night Eating Syndrome and body mass index
Current obesity reports, 2019Co-Authors: Maija B Bruzas, K. C. AllisonAbstract:To review literature on Night Eating Syndrome (NES) and body mass index (BMI, kg/m2) published in the last 5 years. Since December, 2013, 11 studies examined the association between NES and BMI. Five of these studies reported a positive relationship, five showed no relationship, and one produced mixed findings. Emotional Eating and age were moderators. Twelve studies examined whether there was a difference in BMI between those with and without NES with only five of these finding differences. A primary weakness of the recent literature base is that it is almost entirely cross-sectional. Recent findings regarding the relationship between NES and BMI are mixed. Future research should examine the relationship between these variables longitudinally and continue to examine moderating variables that explain why some individuals manifest excess weight with NES and others do not.

disordered Eating and obesity associations between binge Eating disorder Night Eating Syndrome and weight related comorbidities
Annals of the New York Academy of Sciences, 2018Co-Authors: Courtney Mccuenwurst, Madelyn Ruggieri, K. C. AllisonAbstract:Binge-Eating disorder (BED) and Night-Eating Syndrome (NES) are two forms of disordered Eating associated with overweight and obesity. While these disorders also occur in nonobese persons, they seem to be associated with weight gain over time and higher risk of diabetes and other metabolic dysfunction. BED and NES are also associated with higher risk of psychopathology, including mood, anxiety, and sleep problems, than those of similar weight status without disordered Eating. Treatments are available, including cognitive behavior therapy (CBT), interpersonal psychotherapy, lisdexamfetamine, and selective serotonin reuptake inhibitors (SSRIs) for BED; and CBT, SSRIs, progressive muscle relaxation, and bright light therapy for NES.

2016Co-Authors: Namni Goel, Albert J. Stunkard, K. C. Allison, Moonseong Heo, Hans P A Van Dongen, Rexford S Ahima, David E Cummings, Naomi L. Rogers, John P. O’reardon, David F DingesAbstract:Abstract Night Eating Syndrome (NES) is characterized by evening hyperphagia and frequent awakenings accompanied by food intake. Patients with NES display a delayed circadian pattern of food intake but retain a normal sleep-wake cycle. These characteristics initiated the current study, in which the phase and amplitude of behavioral and neuroendocrine circadian rhythms in patients with NES were evaluated. Fifteen women with NES (mean age ± SD, 40.8 ± 8.7 y) and 14 control subjects (38.6 ± 9.5 y) were studied in the laboratory for 3 Nights, with food intake measured daily. Blood also was collected for 25 h (every 2 h from 0800 to 2000 h, and then hourly from 2100 to 0900 h) and assayed for glucose and 7 hormones (insulin, ghrelin, leptin, melatonin, cortisol, thyroid-stimulating hormone [TSH] and prolactin). Statistical analyses utilized linear mixed-effects cosinor analysis. Control subjects displayed normal phases and amplitudes for all circadian rhythms. In contrast, patients with NES showed a phase delay in the timing of meals, and delayed circadian rhythms for total caloric, fat, and carbohydrate intake. In addition, phase delays of 1.0 to 2.8 h were found in 2 food-regulator

Night Eating Syndrome report of a family case
Eating Behaviors, 2016Co-Authors: Guzin Mukaddes Sevincer, K. C. AllisonAbstract:Night Eating Syndrome (NES) represents a circadian delay in the pattern of Eating. As there are genetic links for other Eating- and circadian-based disorders, it is likely that there is a genetic basis for NES as well. We present a family case study of three identified patients and their extensive family history of NES and co-morbid mood disorders. This case report suggested that NES may have a heritable feature, particularly nocturnal ingestions. Of the seven identified cases, four had co-morbid mood disorders, and all descended from a couple with bipolar disorder and delusional disorder. More work is needed to understand the extent of genetic influence on NES, and the relationship between NES and other psychiatric disorders.

an open label efficacy trial of escitalopram for Night Eating Syndrome
Eating Behaviors, 2013Co-Authors: K. C. Allison, Renee H Moore, Stacia Studt, Robert I Berkowitz, Louise Hesson, Jacob Dubroff, Andrew B Newberg, Albert J. StunkardAbstract:Abstract Objective Night Eating Syndrome (NES) has become increasingly recognized as a disorder in need of effective treatments. Selective serotonin reuptake inhibitors have shown efficacy in previous trials, so we sought to expand our understanding of the efficacy of escitalopram in the current trial. Method Thirty-one adults with NES participated in a 12-week open-label trial of escitalopram. Outcome measures included the Night Eating Symptom Scale (NESS), percent of daily intake after the evening meal (% intake) and number of nocturnal ingestions/week (NI), weight, total awakenings/week, mood, and quality of life. Mixed-effects models were used to assess change over time. Results Significant reductions were observed from week 0 to week 12 for the NESS (30.2 to 15.2), % intake (46% to 17%), NI (5.8 to 1.2), weight (90.2 to 88.6 kg), awakenings (8.1 to 2.7), and BDI-II (12.1 to 7.7). Outcomes did not differ significantly by gender, age, race, or psychiatric co-morbidity status. Eighteen of 31 completed 12 weeks of treatment. Discussion This open-label trial of escitalopram showed significant reductions in symptoms associated with NES. Randomized controlled trials are warranted to test these findings. Trial Registration: clinicaltrials.gov identifier: NCT01401595 .

treatment of the Night Eating Syndrome
2011Co-Authors: Albert J. Stunkard, K. C. AllisonAbstract:Treatment of the Night Eating Syndrome (NES) derives in large part from its delayed circadian rhythm of its food intake and neuroendocrine measures. The best established pharmacotherapeutic measures are the Selective Serotonin Reuptake Inhibitors (SSRIs). Studies of the SSRIs have shown rapid normalization of the disordered circadian rhythms, with decreased evening hyperphagia and nocturnal ingestions and increased morning food intake. The serotonergic aspects of NES and its treatment have been supported by the response to another serotonergic agent, d-fenfluramine. There have also been reports of response of Night eaters to topiramate. A more focused effort to alter the circadian rhythm has been phototherapy. Administration of bright light treatment in the morning has proven effective in controlling the Night Eating of a small number of patients. Two forms of psychotherapy have been reported. First, a study of Progressive Muscle Relaxation (PMR) revealed a reduction in anxiety and evening appetite and increases in morning appetite. Second, a pilot study of Cognitive Behavior Therapy (CBT) of 25 Night eaters found a decrease in evening hyperphagia, number of awakenings, and number of nocturnal ingestions. In addition, weight fell by 3.1 kg. Completers had a more favorable outcome than noncompleters.

cognitive behavior therapy for Night Eating Syndrome a pilot study
American Journal of Psychotherapy, 2010Co-Authors: K. C. Allison, J. D. Lundgren, John P Oreardon, Renee H Moore, Albert J. StunkardAbstract:Because no studies of psychotherapy treatments for Night Eating Syndrome (NES) have been published, we conducted a pilot study of a 10-session cognitive behavior therapy (CBT) for NES. Twenty-five patients (19 female, 6 male) were screened and comprehensively assessed before being enrolled. At each visit, patients completed the Night Eating Symptom Scale (NESS), were weighed, and number of awakenings and the number of nocturnal ingestions and daily caloric intake were calculated from weekly food and sleep records. Mixed model regression analyses [of the data] showed significant decreases in caloric intake after dinner (35.0% to 24.9%); number of nocturnal ingestions (8.7 to 2.6 per week); weight (82.5 to 79.4 kg); and NESS score (28.7 to 16.3; all p values <0.0001). Number of awakenings per week, depressed mood, and quality of life also improved significantly (p values <.02). This first clinical trial of CBT for NES shows significant improvements in the core aspects of NES and weight reduction, suggesting the need for a controlled treatment trial.

bright light therapy for the treatment of Night Eating Syndrome a pilot study
Psychiatry Research-neuroimaging, 2015Co-Authors: Ashley Mccune, J. D. LundgrenAbstract:The effect of bright light therapy (BLT) on the symptoms of Night Eating Syndrome was evaluated. Fifteen adults completed two weeks of daily 10,000 lux BLT administered in the morning. Significant reductions were found pre-to-post treatment in Night Eating symptomatology, mood disturbance, and sleep disturbance. This pilot trial provides preliminary support for the efficacy of BLT for the treatment of Night Eating Syndrome.

the Night Eating Syndrome and obesity
Obesity Reviews, 2012Co-Authors: Annette Gallant, J. D. Lundgren, Vicky DrapeauAbstract:The rising prevalence of obesity is a global concern. Eating behaviour and circadian rhythm are proving to be important factors in the aetiology of obesity. The Night-Eating Syndrome (NES) is characterized by increased late-Night Eating, insomnia, a depressed mood and distress. It is evident that prevalence is higher among weight-related populations than the general community. The exact relationship between this Syndrome and obesity remains unclear. The reasons for the discrepancies found in the literature likely include varying diagnostic criteria and a wide range of study population characteristics. NES does not always lead to weight gain in thus certain individuals may be susceptible to Night-Eating-related weight gain. Weight loss through surgical and behavioural treatments has shown success in diminishing symptoms. The increasing literature associating obesity with circadian imbalances strengthens the link between the NES and obesity. Circadian genes may play a role in this Syndrome. This review will examine different aspects of obesity in the context of the NES.

Night Eating patterns of individuals with Eating disorders implications for conceptualizing the Night Eating Syndrome
Psychiatry Research-neuroimaging, 2011Co-Authors: J. D. Lundgren, Ashley Mccune, Carrie D Spresser, Paula Harkins, Lauren Zolton, Konoy MandalAbstract:The prevalence, correlates, and symptom coherence of Night Eating Syndrome (NES) in individuals seeking inpatient treatment for Eating disorders were assessed. Inpatients (n=68; M age=29.8 years; % female=94.1; % diagnosed with anorexia nervosa [AN]=47.1; % diagnosed with bulimia nervosa [BN]=47.1) were interviewed with the Night Eating Syndrome History and Inventory. Additionally, medical charts were reviewed and participants completed measures of Eating behavior and quality of life. NES was diagnosed in 25% of patients; significantly more patients diagnosed with BN meet criteria for NES compared to those diagnosed with AN. In general, patients with NES did not differ from patients without NES on Eating behaviors, attitudes, or quality of life; symptoms of NES frequently co-occurred. This study supports previous research finding that Night Eating behavior is common in individuals diagnosed with Eating disorders.

a biobehavioural model of the Night Eating Syndrome
Obesity Reviews, 2009Co-Authors: Albert J. Stunkard, J. D. Lundgren, K. C. Allison, John P OreardonAbstract:This paper will propose a biobehavioral mechanism for the Night Eating Syndrome (NES), a disorder characterized by a delayed circadian rhythm of food intake and neuroendocrine function. Food intake consists of at least 25% of daily caloric intake after the evening meal and/or at least two Nighttime awakenings with ingestions per week. This will be explored by reviewing neuroimaging of brain serotonin transporters (SERT) and treatment with selective serotonin reuptake inhibitors (SSRIs). SERT binding is elevated in the midbrain of Night eaters, causing dysregulation of the circadian rhythm of both food intake and neuroendocrine function. The administration of SSRIs blocks the reuptake of serotonin and restores the circadian rhythm of both food intake and neuroendocrine function. This hypothesis implies that reduction of SERT activity should increase postsynaptic serotonin transmission and relieve NES. This is precisely the effect of SSRIs. NES is a function of elevated SERT, and blocking of SERT with an SSRI resolves NES. This model of NES attests to the validity of the diagnosis of NES and the criteria by which it is identified, and it provides an explanation of the mechanism.

development of criteria for a diagnosis lessons from the Night Eating Syndrome
Comprehensive Psychiatry, 2009Co-Authors: Albert J. Stunkard, J. D. Lundgren, K. C. Allison, Allan Geliebter, Marci E Gluck, John P OreardonAbstract:Criteria for inclusion of diagnoses of Axis I disorders in the forthcoming Diagnostic and Statistical Manual (DSM-V) of the American Psychiatric Association are being considered. The 5 criteria that were proposed by Blashfield et al as necessary for inclusion in DSM-IV are reviewed and are met by the Night Eating Syndrome (NES). Seventy-seven publications in refereed journals in the last decade indicate growing recognition of NES. Two core diagnostic criteria have been established: evening hyperphagia (consumption of at least 25% of daily food intake after the evening meal) and/or the presence of nocturnal awakenings with ingestions. These criteria have been validated in studies that used self-reports, structured interviews, and symptom scales. Night Eating Syndrome can be distinguished from binge Eating disorder and sleep-related Eating disorder. Four additional features attest to the usefulness of the diagnosis of NES: (1) its prevalence, (2) its association with obesity, (3) its extensive comorbidity, and (4) its biological aspects. In conclusion, research on NES supports the validity of the diagnosis and its inclusion in DSM-V.

proposed diagnostic criteria for Night Eating Syndrome
International Journal of Eating Disorders, 2009Co-Authors: K. C. Allison, J. D. Lundgren, James E Mitchell, John P Oreardon, Allan Geliebter, Marci E Gluck, Piergiuseppe Vinai, Carlos H Schenck, Michael J HowellAbstract:Objective: To propose criteria for diagnosis of the Night Eating Syndrome (NES). Method: An international research meeting was held in April 2008, and consensus criteria for NES diagnosis were determined. Results: The core criterion is an abnormally increased food intake in the evening and Nighttime, manifested by (1) consumption of at least 25% of intake after the evening meal, and/or (2) nocturnal awakenings with ingestions at least twice per week. Awareness of the Eating episodes is required, as is distress or impairment in functioning. Three of five modifiers must also be endorsed. These criteria must be met for a minimum duration of 3 months. Discussion: These criteria help standardize the definition of NES. Additional aspects of the nosology of NES yet to be fully elaborated include its relationship to other Eating and sleep disorders. Assessment and analytic tools are needed to assess these new criteria more accurately. © 2009 by Wiley Periodicals, Inc. Int J Eat Disord 2010

Obesity, 2006Co-Authors: K. C. Allison, Albert J. Stunkard, Thomas A. Wadden, David B Sarwer, Anthony N Fabricatore, Canice E Crerand, Lauren M Gibbons, Rebecca M Stack, Noel N WilliamsAbstract:ALLISON, KELLY C., THOMAS A. WADDEN, DAVID B. SARWER, ANTHONY N. FABRICATORE, CANICE E. CRERAND, LAUREN M. GIBBONS, REBECCA M. STACK, ALBERT J. STUNKARD, AND NOEL N. WILLIAMS. Night Eating Syndrome and binge Eating disorder among persons seeking bariatric surgery: prevalence and related features. Obesity. 2006;14(Suppl 2):77S–82S. Objective: To assess the prevalence of Night Eating Syndrome (NES) and binge Eating disorder (BED) and their related behavioral and psychological correlates in persons who sought bariatric surgery. Research Methods and Procedures: A consecutive series of 215 persons with extreme obesity (82% women, 70% European American) completed the Weight and Lifestyle Inventory and a semistructured interview as part of a presurgery behavioral/psychological assessment. Diagnoses for NES and BED were based on graded diagnostic criteria. Results: Percentages of participants who met diagnostic criteria for NES by interview were 1.9% for the strictest definition and 8.9% across all definitions of NES. After interview, full DSM-TR criteria for BED were met by 4.2%; an additional 1.4% reported binge Eating at least once per week. Self-reported prevalence of NES and BED were higher. Those with NES or BED had significantly more symptoms of depression and a greater history of psychological complications than the remaining sample. Discussion: The prevalence rates of NES and BED among this population of bariatric surgery candidates were lower than expected based on previous reports. Findings and hypotheses regarding lowered prevalence rates are discussed.
