Night eating syndrome (NES) is characterised by recurrent episodes of night eating, evident through excessive food consumption after the evening meal or eating after awakening from sleep, often associated with significant distress and/or impairment in functioning. This scoping review was conducted according to PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews) guidelines. The search was conducted through the use of PubMed, Medline (OVID) and SCOPUS, to identify relevant articles published within the last 10 years. Search terms including "Night eating*" OR "NES" and Boolean phrases were used to refine the search. Additionally, the age of participants was restricted to 18 years and above, to ensure only adult participants were included. The abstracts of the remaining articles were used to screen for those that were relevant. From a total of 663 citations, 30 studies assessing night eating syndrome met the inclusion criteria to be included in the review. We found inconsistent associations of NES with higher body mass index (BMI), less physical activity, type 2 diabetes mellitus (T2DM) and poorer quality of sleep. These inconsistencies may have been due to the use of different measurement methods, lack of power from small sample sizes of NES in some studies and varying ages of participants, with associations being more likely to be found in higher-quality, representative populations than in university student samples. There were no associations of NES with T2DM in clinical populations and with hypertension, OSA and metabolic syndrome, but sample sizes were small. The impacts of NES on these medical conditions should be addressed in future, using well-sized and long-term studies involving representative populations of adults. In conclusion, NES likely has negative impacts on BMI, T2DM, physical activity, and sleep quality, which in turn may increase cardio-metabolic risk. However, further research is needed to elucidate the interaction between NES and its associated features.
夜间进食综合征（NES）的特征是反复发作的夜间进食，表现为晚餐后或从睡眠中醒来后过量进食，常伴有明显的痛苦和/或功能障碍。本综述按照 PRISMA-ScR（系统评价和荟萃分析的首选报告项目用于范围综述）指南进行。通过使用 PubMed、Medline（OVID）和 SCOPUS 进行检索，以确定过去 10 年内发表的相关文章。使用“夜间进食*”或“NES”等搜索词和布尔短语来精炼搜索。此外，参与者的年龄限制在 18 岁及以上，以确保仅纳入成年参与者。其余文章的摘要用于筛选相关文章。从总共 663 条引文，有 30 项研究评估了夜间进食综合征，符合纳入标准纳入本综述。我们发现 NES 与较高的体重指数（BMI）、较少的体力活动、2 型糖尿病（T2DM）和较差的睡眠质量之间的关联不一致。这些不一致可能是由于使用了不同的测量方法，一些研究中 NES 的样本量较小，参与者的年龄不同，在高质量、代表性人群中更有可能发现关联，而不是在大学生样本中。在临床人群中，NES 与 T2DM 之间没有关联，与高血压、OSA 和代谢综合征之间也没有关联，但样本量较小。未来应该在更大规模和长期的研究中，使用代表性的成年人样本，来研究 NES 对这些疾病的影响。总之，NES 可能对 BMI、T2DM、体力活动和睡眠质量产生负面影响，进而可能增加心血管代谢风险。然而，需要进一步的研究来阐明 NES 及其相关特征之间的相互作用。
