“…However, it was only evening hyperphagia and not nocturnal ingestion, that showed an independent and significant association with a higher BMI. This finding suggests that individuals with high BMI are more prone to developing evening hyperphagia, which is partly in line with a report showing that obesity is less common in individuals with nocturnal ingestion than in those with evening hyperphagia [17]. In individuals with obesity, the comorbidity of NES interferes with weight loss [65,66], but this phenomenon might be caused by evening hyperphagia and not nocturnal ingestion.…”

“…Based on the A1 criterion (evening hyperphagia) of "At least 25% of the daily food is consumed after the evening meal," participants who had dinner as well as snacked between dinner and the next morning and consumed at least 25% of their daily calories between dinner and bedtime every day were identified as having met the A1 criterion and defined as having evening hyperphagia. They included some participants who also met the A2 criterion [17]. According to the A2 criterion (nocturnal ingestion) of "At least two eating episodes per week occur upon awakening during the night," participants whose last episodes of eating/drinking were later than their sleep onset time at least twice a week (both workdays and days off) were identified.…”

“…A recent video polysomnography study showed that participants with nocturnal ingestion were younger and less obese than those with evening hyperphagia [17]. Additionally, in terms of eating and subsequent falling asleep behaviors, the participants in the evening hyperphagia group had significantly longer eating episodes and sleep resumption times after eating offset than those in the nocturnal ingestion group [17]. However, no studies have examined the differences in the psychological burden and lifestyle-related factors, including sleep variables, between evening hyperphagia and nocturnal ingestion.…”

A Cross-Sectional Study of Evening Hyperphagia and Nocturnal Ingestion: Core Constituents of Night Eating Syndrome with Different Background Factors

This web-based cross-sectional survey aimed to elucidate the differences between the two core symptoms of night eating syndrome (NES): evening hyperphagia and nocturnal ingestion in the general Japanese population aged 16–79 years. Participants who consumed at least 25% of daily calories after dinner were defined as having evening hyperphagia. Those who consumed food after sleep initiation at least twice a week were determined to have nocturnal ingestion. Of the 8348 participants, 119 (1.5%) were categorized in the evening hyperphagia group, 208 (2.6%) in the nocturnal ingestion group, and 8024 in the non-NES group. Participants with evening hyperphagia and nocturnal ingestion had significantly higher anxiety scores (p < 0.05 and p < 0.001, respectively) and depression (p < 0.001 for both) than those without NES. Multiple logistic regression analysis revealed that evening hyperphagia was significantly and independently associated with higher body mass index, shorter sleep duration, later sleep-wake schedule, and higher insomnia score, while nocturnal ingestion was significantly and independently associated with younger age, smoking habit, living alone, earlier sleep-wake schedule, and higher insomnia score. Sleep duration and sleep-wake schedule characteristics in the two groups were opposite, suggesting differences in the sleep pathophysiology mechanisms.

BackgroundNight eating syndrome (NES) is included in the Diagnostic and Statistical Manual for Mental Disorders, 5th edition, as an example of “Other Specified Feeding or Eating Disorders” with minimal guidance about how to define and operationalize NES. The literature suggests that research practices vary widely, making it difficult to draw conclusions about the public health burden of, effective interventions for, or policy implications relevant to NES. This Forum article seeks to illustrate the lack of definitional agreement to underscore the need for a consensus about NES diagnostic criteria, and to propose steps toward closing knowledge gaps and achieving consensus.MethodWe searched PubMed and PsycINFO titles and abstracts, using “NES” as the search term, for research articles published in English between January 1, 2013 to August 12, 2024 with sample sizes of NES > 10 and ages 18 or older. Eligible articles were coded for NES definitions and assessment method used to diagnose participants with NES and for information about comorbidity of NES and any other eating disorder (ED).ResultsSeventy‐three articles met inclusion criteria. Most commonly, NES was diagnosed using a diagnostic criteria set (35/73) or a symptom score threshold (34/73); among the former, only eight studies employed DSM‐5 NES criteria. Thirteen studies, varying widely in methodology, examined comorbidity with other EDs, most commonly binge‐eating disorder where comorbidity was high.ConclusionHeterogeneity of definitions and assessment impede progress in the study of NES. We propose strategies for developing a consensus definition and addressing research gaps.
