“…28 Alcohol also has a direct effect on the rapid eye movement phase of the sleep cycle, and alters the sleep-wake cycle with hormone changes which is likely impairing sleep in both cohorts. 29 Therefore, binge drinking can affect directly on player wellbeing and performance, as such must be addressed within the team culture through education and awareness. In addition, the high alcohol intake seen in the age-matched cohort is an area of public health concern and would likely benefit from increased awareness and education.…”

Objective: To study sleep quality and sleep hygiene in professional athletes and an age-matched cohort. Design: Cross-sectional study. Setting: Professional athletes and a sport medicine center. Participants: Professional rugby, netball and football athletes (n = 184) and attendees to a sport medicine center (n = 101). Interventions: Participants completed an online survey. Main Outcome Measures: Sleep Hygiene Index (SHI) and Pittsburgh Sleep Quality Index (PSQI). Results: Forty-five percent (n = 128) of respondents were aged between 18 and 24 years, 54% (n = 154) were men and 65% (n = 184) were professional athletes. The sleep duration of the professional athletes (mean rank 134.3, n = 181) was greater than the age-matched cohort (mean rank = 154.4, n = 101), U = 7835.0, z = −2.3, P = 0.02; however, they reported more sleep disturbance (mean ranking = 148.0, n = 181) than the age-matched cohort (mean rank = 129.8, n = 101), U = 7960.5 z = −2.5, P = 0.01, 2–tailed. Professional athletes had worse sleep regularity (mean rank = 152.3, n = 183) compared with the age-matched cohort (mean rank = 124.6, n = 101), U = 7448.5, z = −2.7, P = 0.006, 2-tailed, had an inferior sleep environment (mean rank = 149.5, n = 183) compared with the age-matched cohort (mean rank = 129.8, n = 101), U = 7959.5, z = −2.0, P = 0.047, and had more naps (mean rank = 156.2, n = 183) compared with the age-matched cohort (mean rank = 117.6, n = 101), U = 6729.0, z = −4.2, P = 0.00 0, 2-tailed. Conclusions: Professional athletes reported poorer sleep quality and sleep hygiene compared with an age-matched cohort, and difficulty falling asleep following competition. It is likely this is due to the stress of competition, training, and traveling. Because sleep plays an important role in postexercise recovery and has an impact on injury and athletic performance, it is important to have strategies to support better sleep quality and sleep hygiene in athletes.

“…Eating and sleeping are two critical parts of human survival, and these two parts interact with circadian rhythms and hormonal regulation [6]. Sleep problems are characterised by various difficulties, including difficulty initiating sleep, difficulty maintaining sleep, non-restorative sleep Knudsen et al [7], and related symptoms or disorders such as sleep-disordered breathing, irregular sleep patterns (e.g., circadian rhythm sleep-wake disorders), parasomnia (e.g., sleepwalking, confusional arousals, night terrors, sleep talking, and nightmares), and sleep-related movement disorders (e.g., restless leg syndrome).…”

“…These issues with sleep can be assessed using various methods, including polysomnography, actigraphy, sleep diaries, Multiple Sleep Latency Testing, the Epworth Sleepiness Scale, the Fatigue Severity Scale, and the Insomnia Severity Index [8]. Sleep deprivation has been shown to have a negative impact on hormones that control appetite, namely leptin and ghrelin, which can lead to an abnormal increase in appetite [6]. In sleep studies conducted with patients diagnosed with anorexia and bulimia, it has been shown that people have reduced sleep maintenance and increased night-time awakenings [1].…”

Sleep and diet are essential for maintaining physical and mental health. These two factors are closely intertwined and affect each other in both timing and quality. Eating disorders, including anorexia nervosa and bulimia nervosa, are often accompanied by different sleep problems. In modern society, an increasing number of studies are being conducted on the relationship between eating disorders and sleep. To gain a more comprehensive understanding of this field and highlight influential papers as well as the main research domains in this area, a scientometric approach was used to review 727 publications from 1971 to 2023. All documents were retrieved from Scopus through the following string “TITLE-ABS ((“sleep” OR “insomnia”) AND (“anorexia nervosa” OR “bulimia nervosa” OR “binge eating” OR “eating disorder*”) AND NOT “obes*”) AND (LIMIT-TO (LANGUAGE, “English”))”. A document co-citation analysis was applied to map the relationship between relevant articles and their cited references as well as the gaps in the literature. Nine publications on sleep and eating disorders were frequently cited, with an article by Vetrugno and colleagues on nocturnal eating being the most impactful in the network. The results also indicated a total of seven major thematic research clusters. The qualitative inspection of clusters strongly highlights the reciprocal influence of disordered eating and sleeping patterns. Researchers have modelled this reciprocal influence by taking into account the role played by pharmacological (e.g., zolpidem, topiramate), hormonal (e.g., ghrelin), and psychological (e.g., anxiety, depression) factors, pharmacological triggers, and treatments for eating disorders and sleep problems. The use of scientometric perspectives provides valuable insights into the field related to sleep and eating disorders, which can guide future research directions and foster a more comprehensive understanding of this important area.

“…The sleep-related eating disorder (SRED) is considered to relate to sleep disorders rather than to eating disorders. SRED and NES both include NI, and although the differences between SRED and NES are somewhat controversial, it is useful to differentiate between them [ 27 ]. SRED is considered to be a sleep disorder (parasomnia) whereas NES is considered to be an eating disorder.…”

“…For this reason, SRED was excluded from the new NES diagnostic criteria in the DSM-5, as it was considered a unique diagnosis representing a sleep disorder and not an ED [ 2 , 14 ]. Despite this classification, the relationships between NES, ED, and SRED still elicit debate in the literature [ 11 , 14 , 27 , 29 , 30 ].…”

Night eating syndrome (NES) is an eating disorder (ED) characterized by nocturnal ingestion (NI), evening hyperphagia, morning anorexia, as well as mood and sleep disturbances. This study compared subjective and objective sleep quality and ED-related psychopathologies in patients seeking treatment for ED. Method: The sample was composed of 170 women, aged 18–68, who were referred for an ED assessment from 2011 to 2020. The participants were divided into three subgroups: NES-NI only (n = 30), NES+ binge eating (BE) (including binge eating disorders or bulimia nervosa (n = 52), and BE-only (n = 88). The measures consisted of a psychiatric evaluation, objective sleep monitoring measured by an actigraph for 1 week, a subjective sleep self-report, and ED-related psychopathology questionnaires. Results: Objective sleep monitoring revealed significant group differences, with higher sleep efficiency in participants with BE-only and longer sleep durations for the NES-NI only group. Subjectively, the BE-only group described a significantly lower sleep quality than either the NES-NI only or the NES+BE groups. ED-related psychopathology was lower in the NES-NI-only group. A stepwise linear regression revealed that general psychopathology (the brief symptom inventory total score) was a significant predictor of subjective sleep quality. Conclusion: NES-NI-only was correlated with less psychopathology, but with more subjective and objective sleep disturbances. These results lend weight to the supposition that NES lies on a continuum of ED psychopathologies, and that NES-NI-only appears to be a separate entity from NES+BE and BE-only in terms of its psychopathology.
