“…Following article screening, a total of 51 studies were entered into the initial random effects model. Outlier analyses identified a total of ten studies 49 – 58 and these were subsequently excluded from the analysis (See Supplemental S2 for details of these studies including the 95% CI for each excluded effect size). Heterogeneity was reduced after excluding these studies (prior to exclusion I 2 = 77.9%, Q(52) = 235.11, p < 0.001, after exclusion I 2 = 60.2%, Q(42) = 105.5, p < 0.001) but remained substantial and significant.…”

Eveningness, a preference for later sleep and rise times, has been associated with a number of negative outcomes in terms of both physical and mental health. A large body of evidence links eveningness to Major Depressive Disorder (MDD). However, to date, evidence quantifying this association is limited. The current meta-analysis included 43 effect sizes from a total 27,996 participants. Using a random-effects model it was demonstrated that eveningness is associated with a small effect size (Fisher’s Z = − 2.4, 95% CI [− 0.27. − 0.21], p < 0.001). Substantial heterogeneity between studies was observed, with meta-regression analyses demonstrating a significant effect of mean age on the association between diurnal preference and depression. There was also evidence of potential publication bias as assessed by visual inspection of funnel plots and Egger’s test. The association between diurnal preference and depression is small in magnitude and heterogenous. A better understanding of the mechanistic underpinnings linking diurnal preference to depression and suitably powered prospective studies that allow causal inference are required.

“…A large body of evidence demonstrated that poor sleep quality or sleep disorders mediate the association between evening chronotype and depressive symptoms in healthy subjects and patients with mood disorders ( Van den Berg et al, 2018 ; Caruso et al, 2020 ; Li et al, 2020 ; Tian et al, 2020 ; Uzer and Yucens, 2020b ; Lin et al, 2021 ; Zhou et al, 2021 ) or other adverse outcomes ( Cox and Olatunji, 2019 ; Kandeger et al, 2019 ; Najem et al, 2020 ; Bradford et al, 2021 ). A study of older adults with depression indicated that the relationship between evening chronotype and depression is fully mediated by insomnia severity ( Uzer and Yucens, 2020b ). Clinical evaluation of patients with BD indicated that poor sleep quality mediated the association between evening chronotype and residual depressive symptoms ( Caruso et al, 2020 ).…”

Chronotype, circadian rhythm, and psychiatric disorders: Recent evidence and potential mechanisms

et al. 2022

The circadian rhythm is crucial for physiological and behavioral functions. Chronotype, which represents individual preferences for activity and performance, is associated with human health issues, particularly psychiatric disorders. This narrative review, which focuses on the relationship between chronotype and mental disorders, provides an insight into the potential mechanism. Recent evidence indicates that (1) the evening chronotype is a risk factor for depressive disorders and substance use disorders, whereas the morning chronotype is a protective factor. (2) Evening chronotype individuals with bipolar disorder tend to have more severe symptoms and comorbidities. (3) The evening chronotype is only related to anxiety symptoms. (4) The relationship between chronotype and schizophrenia remains unclear, despite increasing evidence on their link. (5) The evening chronotype is significantly associated with eating disorders, with the majority of studies have focused on binge eating disorders. Furthermore, the underlying mechanisms or influence factors are described in detail, including clock genes, brain characteristics, neuroendocrinology, the light/dark cycle, social factors, psychological factors, and sleep disorders. These findings provide the latest evidence on chronotypes and psychiatric disorders and serve as a valuable reference for researchers.

“…Consistent with previous research, people with eveningness-preference have poorer sleep hygiene practices, meaning they tend to engage in environmental and behavioral habits that lower sleep quality (e.g., drinking coffee or alcohol before sleep, irregular sleep time, improper temperature or light in the bedroom, etc. ), and thus have more insomnia symptoms ( 45 ). Prior studies have also found that patients with eveningness preference showed poorer response to classic insomnia treatments, thereby suggesting that chronotype might be related to the development of psychiatric diseases through distinct mechanisms ( 46 – 48 ).…”

ObjectiveCircadian preference and mental health disorders are closely related to insomnia. This study aimed to evaluate insomnia symptoms in textile factory workers with different work schedules, and to investigate the association between insomnia, morningness–eveningness preference, anxiety, and depression.MethodsA total of 3,883 textile workers were assessed using the 3-items of Pittsburg Sleep Quality Index, Composite Scale of Morningness, Beck Anxiety Inventory, Center for Epidemiologic Studies-Depression Scale, and socio-demographic questionnaires.ResultsThe prevalence rate of insomnia in textile workers was 16.7% (N = 646), with 49.8% (N = 322) were shift workers. Among shift workers (N = 1,833), 9.5% had difficulty initiating sleep, and almost 9.0% suffered from early morning awakening, a rate significantly higher than among daytime workers. Logistics regressions revealed that work schedule was insignificantly associated with insomnia. Depression (OR = 1.034, 95% CI = 1.022–1.046) and anxiety (OR = 1.031, 95% CI = 1.018–1.043) positively predicted insomnia, whereas morningness preference (OR = 0.977, 95% CI = 0.960–0.995) decreased the likelihood of insomnia. Furthermore, mediation analysis showed that both anxiety and depression independently mediated the association between circadian preferences and insomnia in textile workers with or without shift work.ConclusionThis study highlighted the insomnia, depression, and anxiety of textile factory workers in a Chinese textile factory. To improve insomnia symptoms, interventions to promote morningness circadian preference and reduce depressive and anxious symptoms among workers are encouraged.
