Abstract
STUDY OBJECTIVES Insomnia is a common sleep disorder and constitutes a major issue in modern society. We provide new clues for revealing the association between environmental chemicals and insomnia. METHODS Three genome-wide association studies (GWAS) summary datasets of insomnia (n = 113,006, n = 1,331,010, and n = 453,379, respectively) were driven from the UK Biobank, 23andMe, and deCODE. The chemical-gene interaction dataset was downloaded from the Comparative Toxicogenomics Database. First, we conducted a meta-analysis of the three datasets of insomnia using the METAL software. Using the result of meta-analysis, transcriptome-wide association studies were performed to calculate the expression association testing statistics of insomnia. Then chemical-related gene set enrichment analysis (GSEA) was used to explore the association between chemicals and insomnia. RESULTS For GWAS meta-analysis dataset of insomnia, we identified 42 chemicals associated with insomnia in brain tissue (p < 0.05) by GSEA. We detected five important chemicals such as pinosylvin (p = 0.0128), bromobenzene (p = 0.0134), clonidine (p = 0.0372), gabapentin (p = 0.0372), and melatonin (p = 0.0404) which are directly associated with insomnia. CONCLUSION Our study results provide new clues for revealing the roles of environmental chemicals in the development of insomnia.

Kim HY, Choi J, Lim HM, Park C, Hong YC. The association between non-regular work patterns and insomnia among Korean wage workers: the fifth Korean working condition survey. Ann Occup Environ Med 2021; 33:e9. [PMID: 34754470 PMCID: PMC8075738 DOI: 10.35371/aoem.2021.33.e9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Accepted: 03/05/2021] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Non-regular workers are steadily increasing on account of improving corporate productivity. They are classified as non-permanent, part-time, or non-typical workers. Non-regular work has a negative impact on workers' physical and mental health. This study analyzed the relationship between non-permanent, part-time and non-typical work and insomnia among Korean wage workers, and investigated the differences and interactions between different work patterns. METHODS The Fifth Korean Working Conditions Survey was used in this study. Non-regular work patterns were classified into 7 types: type 1, sole non-permanent; type 2, sole part-time; type 3, sole non-typical; type 4, part-time-non-typical; type 5, non-permanent-non-typical; type 6, non-permanent-part-time; type 7, all inclusive. Insomnia was measured on a scale from "normal sleep" to "insomnia" based on the 3-item Minimal Insomnia Symptom Scale. Multiple logistic regression was used to analyze the association between non-regular work patterns and insomnia among wage workers. RESULTS After multivariate adjustment, a significantly increased odds ratio (OR) for insomnia was found in types 1, 2, 3, 4, 5, 6, and 7 of non-regular work patterns compared to regular work patterns. After stratification for shift and night work, the OR of the group with shift and night work was higher than that of the group without shift and night work. CONCLUSIONS Insomnia was significantly associated with non-regular work patterns. This association was prominent in workers with shifts and night work. This finding suggests that proper work patterns may be needed to reduce the risk of insomnia among Korean wage workers and workers who initially had insomnia should consider these results before placement.

Abstract
Background Self-rated health (SRH), a subjective perception of an individual’s overall health, is widely used in public health assessment. The transition from adolescence to young adulthood is a critical period involving substantial changes in lifestyle and dietary habits. Therefore, it is important to understand SRH among young Japanese females. The present study aimed to investigate the relationships between SRH among female healthcare students and their lifestyle factors, such as living status (living with others or living alone), smoking habit, alcohol consumption, frequency of breakfast consumption (FBC), physical activity, insomnia, and physique recognition. Methods A cross-sectional survey was conducted on 1101 female healthcare students in Japan. The body mass index was calculated from the body height and weight using data from periodic health examinations. Self-reported sociodemographic, lifestyle or dietary habits, physical activity, and SRH were used through a self-administered questionnaire. Participants were classified as having either good SRH (excellent, very good, or good) or impaired SRH (fair or poor). Multivariate logistic regression analysis was performed to investigate the independent relationships between SRH and lifestyle factors. Results A total of 11.4% participants demonstrated impaired SRH. Multivariate logistic regression analysis showed that the University of California Los Angeles activity score, Athens Insomnia Scale, and physique recognition were associated with SRH. Conclusions It was suggested that public health activities that consider physical activity, sleep, and physique recognition may help maintain and improve SRH in female university students in Japan.

Abstract
Background: Shorter sleep duration and lower sleep quality have been previously associated with greater obesity risk among adult samples. Food insecurity has also been found to impact sleep patterns and obesity. Yet few studies have explored associations between sleep, food insecurity, and obesity in adolescent populations, who may have more irregular sleep patterns. Thus, the objectives of this study were to determine associations between measures of sleep, food insecurity, and weight status. Methods: Data were obtained from the Family Life, Activity, Sun, Health, and Eating (FLASHE) Study, an online cross-sectional study of parent and adolescent (12-17-year old) dyads. Participants were drawn from a Consumer Opinion Panel representative of the general population of the United States with respect to sex, education, income, age, household size, and region. First, multinomial logistic regression analyses were conducted to determine associations between sleep measures (adolescent-reported average nighttime sleep duration, having a regular bedtime, and having difficulty staying asleep), food insecurity (a validated two-item parent-reported measure), and weight status (being underweight, of healthy weight, overweight, and obese). Weight status was based upon adolescent BMI z-scores using Centers for Disease Control and Prevention growth charts using information from parent report of adolescent height and weight and adolescent-reported age and sex among adolescents (N = 1544). Conditional process models were also fitted to the data to determine whether food insecurity moderates the associations between sleep measures and weight status, and to determine whether the association between food insecurity and weight status is mediated by average sleep duration. Results: Compared to those with food security, a greater percentage of those with food insecurity reported having difficulties staying asleep and a longer average sleep duration. Multinomial logistic regression models demonstrated that having a regular bedtime was associated with lower odds of having obesity, having difficulties staying asleep was associated with greater odds of being underweight, and having food insecurity was associated with greater odds of being overweight. Conditional process models demonstrated that food insecurity did not moderate associations between sleep measures and weight status and that average nighttime sleep duration did not mediate the association between food insecurity and weight status. Conclusions: This is one of the first studies to examine associations between sleep, food insecurity, and weight status among adolescents. Results provide additional support for the need to uncover mechanisms for how sleep and food insecurity affect pediatric obesity using longitudinal data.

Arousability as a trait predisposition to insomnia: multidimensional structure and clinical utility of the Spanish and English versions of the Arousal Predisposition Scale. Sleep Med 2021; 81:235-243. [PMID: 33721601 DOI: 10.1016/j.sleep.2021.02.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 12/18/2020] [Accepted: 02/15/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVES Traits related to a hyper-reactive arousal system (arousability) and weakened sleep system (sleep reactivity) are considered predisposing factors for insomnia of potential clinical utility. However, research examining the psychometric properties (ie, reliability and validity) of the Arousal Predisposition Scale (APS) and its clinical utility (ie, cut-off scores) among population-based and clinical samples is very limited. METHODS A total of 500 adults (41.8% female, 39.1 ± 15.9 years) from the general population in Spain and 217 adults (64.5% female, 46.0 ± 16.1 years) from a clinical sample in the United States completed the APS, as well as measures of sleep reactivity, insomnia severity, anxiety, depression, and stress. Structural equation modeling was used to conduct confirmatory factor analysis (CFA) of the APS. Correlation and receiver operating characteristic (ROC) analyses were used to determine convergent and predictive validity of the APS and its factors. RESULTS The CFAs supported two dimensions of emotional reactivity (APS-ER, 9 items) and trait anxiety (APS-TA, 3 items) in both independent samples. APS-ER was associated with sleep reactivity and performed better than APS-TA when predicting clinically significant sleep reactivity and similarly when predicting clinically significant insomnia severity. CONCLUSIONS Our findings support the specificity of emotional reactivity and sleep reactivity as trait predispositions to insomnia, while trait anxiety is a predisposing factor for the comorbidity of insomnia with state anxiety rather than a specific diathesis for insomnia. These data provide further support for the diathesis-stress model of insomnia and, as a transdiagnostic process, its potential etiological link with psychopathology.

Abstract
Background: Insomnia causes a huge socioeconomic burden among the elderly, and is not simply a health problem. This study aimed to determine the comparative advantage of the effectiveness and acceptability of non-pharmacological interventions available for elderly individuals with insomnia. Methods: Comprehensive searches in 13 medical databases were performed to find relevant randomized controlled trials (RCTs) up to August 2019. Two independent reviewers performed study selection, data extraction, and quality assessment of included RCTs using the Cochrane Collaboration's risk of bias. A network meta-analysis within the frequentist model was performed by combining direct and indirect evidence from all available RCTs. The primary outcomes were effectiveness as measured by the Pittsburgh Sleep Quality Index (PSQI) total score and acceptability by the incidence of all-cause drop-out. Results: Twenty-eight RCTs involving 2,391 participants were included. Compared to wait-list, acupuncture (standardized mean difference -4.37, 95% confidence interval -8.53 to -0.12), acupuncture combined with benzodiazepines (-5.20, -9.82 to -0.57), behavioral therapy (-10.44, -17.31 to -3.58), benzodiazepines (-4.28, -8.45 to -0.11), benzodiazepines combined with cognitive behavioral therapy (CBT) (-7.18, -12.17 to -2.19), and CBT (-4.93, -8.63 to -1.22) showed significant superiority in their effectiveness. No significant comparative superiority or inferiority was found in terms of acceptability. Conclusions: In terms of effectiveness as indicated by the PSQI total score, compared to wait-list, superior benefits were observed for acupuncture, acupuncture combined with benzodiazepines, behavioral treatment, benzodiazepines, benzodiazepines combined with CBT, and CBT. Importantly, combined treatments, including benzodiazepines combined with CBT or with acupuncture, were generally superior to other monotherapies. In terms of acceptability, there was not enough data to draw conclusions. However, most RCTs included had methodological problems related to the lack of blinding procedure, suggesting a risk of effect size overestimation. Registration: CRD42019145518.

Abstract
INTRODUCTION This study examined sleep disturbances in first-time fathers from the third trimester of their partner's pregnancy to 2 months postpartum to determine prevalence, incidence, and persistence of sleep disturbances and identify associated determinants. METHODS Men expecting their first child were recruited from local prenatal classes and university-affiliated obstetric clinics. During their partner's third trimester of pregnancy and 2 months postpartum, 459 men completed standardized online self-report questionnaires measuring sociodemographics, lifestyle, and psychosocial variables and sleep quality. RESULTS Disturbed sleep (Pittsburgh Sleep Quality Index [PSQI] global score >5) increased from 29.6% during the third trimester to 44.7% at 2 months postpartum. The incidence of poor sleep at 2 months postpartum was 33.7%. Among men with disturbed sleep at the antenatal assessment, 70.6% continued to have sleep disturbances at 2 months postpartum. An increase in depressive symptoms and higher parenting stress was independently associated with onset and persistence of disturbed sleep at 2 months postpartum. CONCLUSIONS Sleep is compromised in expectant and new fathers. Strategies aimed at improving sleep, depressed mood, and managing the challenges of parenting may be important components to include in prenatal interventions aimed at enhancing the transition to parenthood and infant development.

Abstract
The objective of this randomized controlled trial was to test whether a commercially available, mindfulness meditation mobile app, (i.e., Calm app), was effective in reducing fatigue (primary outcome), pre-sleep arousal, and daytime sleepiness (secondary outcomes) in adults with sleep disturbance (Insomnia Severity Index Score >10) as compared to a wait-list control group. Associations between the use of the Calm app (i.e., adherence to the intervention) and changes in sleep quality was also explored in the intervention group only. Adults with sleep disturbance were recruited (N = 640). Eligible and consenting participants (N = 263) were randomly assigned to the intervention (n = 124) or a wait-list control (n = 139) group. Intervention participants were asked to meditate using the Calm app ≥10 minutes/day for eight weeks. Fatigue, daytime sleepiness, and pre-sleep arousal were assessed at baseline, mid- (4-weeks) and post-intervention (8-weeks) in both groups, whereas sleep quality was evaluated only in the intervention group. Findings from intent-to-treat analyses suggest the use of the Calm app for eight weeks significantly decreased daytime fatigue (p = .018) as well as daytime sleepiness (p = .003) and cognitive (p = .005) and somatic (p < .001) pre-sleep arousal as compared to the wait-list control group. Within the intervention group, use of the Calm app was associated with improvements in sleep quality (p < .001). This randomized controlled trial demonstrates that the Calm app can be used to treat fatigue, daytime sleepiness, and pre-sleep arousal in adults with sleep disturbance. Given that the Calm app is affordable and widely accessible, these data have implications for community level dissemination of a mobile app to improve sleep-related symptoms associated with sleep disturbance.

Abstract
This empirical study aims to investigate factors associated with insomnia symptoms during the COVID-19 pandemic in 4,921 Norwegian adults. Participants were queried across two time-points, between March 31st and April the 7th 2020, and between June 22nd and July 13th, 2020. Relevant risk factors and psychological correlates at the first time-point and insomnia symptoms were measured 3 months later, allowing for the investigation of concurrent associations as well as associations across time. Insomnia symptoms were measured with the Bergen Insomnia Scale. The results revealed that individuals reported higher mean levels of insomnia symptoms during the COVID-19 lockdown, compared to pre-pandemic surveys from 2008 (p < 0.0001, Cohen's d = 0.29). Individuals who predominantly socially distanced reported higher mean levels of insomnia symptoms than those who did not predominantly distance. Females, individuals with lower education levels, individuals who had lost their job, and individuals who declared having been diagnosed with an unspecified pre-existing psychiatric disorder reported the most symptoms. The regression model (R2 = 0.44) showed that physical exercise, was associated with less symptoms of insomnia. Symptoms of health Anxiety, symptoms of depression, unhelpful coping strategies, worry about job and economy, and older age were all associated with higher levels of insomnia symptoms. These findings highlight particularly vulnerable subgroups, as well as providing clinicians with key areas of intervention to help individuals suffering from insomnia symptoms.

Abstract
OBJECTIVE To investigate the association between alcohol consumption and incidence of sleep disorder. METHODS PubMed, EMBASE and OVID were searched systematically until March 2020 for cohort studies quantitatively investigating the effect of alcohol on incident sleep disorder. We conducted a random-effects meta-analysis to calculate the summary ORs (odds ratios) and 95 %CIs (confidence intervals) on the incidence of sleep disorder in relation to alcohol consumption. RESULTS The pooled analysis of eleven included cohort studies demonstrated that general drinking was significantly associated with incidence of sleep disorder (OR:1.37, 95 %CI:1.22,1.54,I² = 0.0 %) while heavy drinking was not (OR:1.22, 95 %CI:0.94,1.60, I² = 81.1 %). (general drinking (women <24 g/day; men <48 g/day; < 4 times/week), heavy drinking (women ≥24 g/day; men ≥48 g/day; ≥ 4times/week)). CONCLUSIONS Findings from the present systematic review and meta-analyses showed that there was no evidence that alcohol consumption diminished sleep problems, and some evidence that general drinking might increase the sleep problems, but further study is necessary.

Abstract
Over the past decades, there has been an increase in overweight and obesity worldwide rates in both in adult and children. In parallel, it has been reported a worsening of sleep duration and quality. Some studies have shown an association between obesity and sleep disturbances (SD) vice versa, subjects with obesity have a greater risk of SD. As well as SD influences diet, also food choices have been shown to influence various sleep-related variables, such as duration and quality. For this reason, nutrition could represent an important tool not only to lose weight but also to improve sleep in patients with obesity and sleep disturbances. Thus, the aim of this review is to provide an overview of the studies that assessed the association between obesity and SD and vice versa, highlighting possible nutritional advices as a tool to improve sleep in patients with obesity and sleep disturbances.

Abstract
OBJECTIVE This study assessed the consequences of childhood traumatic brain injury (TBI) on sleep, fatigue, depression, and quality of life (QoL) outcomes and explored the relationships between these variables at 20 years following childhood TBI. PARTICIPANTS We followed up 54 young adults with mild, moderate, and severe TBI, and 13 typically developing control (TDC) participants, recruited at the time of TBI. METHODS Sleep was assessed with the Pittsburgh Sleep Quality Index and actigraphy. RESULTS At 20 years postinjury, results showed no significant difference between whole TBI group and TDC participants on subjective sleep quality; however, the moderate TBI group reported significantly poorer subjective sleep quality compared to those with severe TBI. Poorer subjective sleep was associated with increased symptoms of fatigue, depression, and poorer perceptions of General Health in the TBI group. Actigraphic sleep efficiency, fatigue, depression, and QoL outcomes were not significantly different between TBI and TDC or among TBI severity groups. CONCLUSIONS These preliminary findings underscore associations between subjective sleep disturbance, fatigue, depression, and QoL in this TBI sample, and mostly comparable outcomes in sleep, fatigue, depression, and QoL between the TBI and TDC groups. Further research is required to clarify these findings.

Abstract
Caffeine occurs naturally in various foods, such as coffee, tea, and cocoa, and it has been used safely as a mild stimulant for a long time. However, excessive caffeine consumption (1~1.5 g/day) can cause caffeine poisoning (caffeinism), which includes symptoms such as anxiety, agitation, insomnia, and gastrointestinal disorders. Recently, there has been increasing interest in the effect of caffeine consumption as a protective factor or risk factor for neurological and psychiatric disorders. Currently, the importance of personalized medicine is being emphasized, and research on sex/gender differences needs to be conducted. Our review focuses on the effect of caffeine consumption on several neurological and psychiatric disorders with respect to sex differences to provide a better understanding of caffeine use as a risk or protective factor for those disorders. The findings may help establish new strategies for developing sex-specific caffeine therapies.

Abstract
STUDY OBJECTIVES Racial and ethnic minorities are more likely to suffer from insomnia that is more severe; however, few studies have examined mechanisms by which racial disparities in severity of insomnia disorder may arise. One potential mechanism for disparities in insomnia severity is perceived discrimination. This study tested discrimination as a mediator in the relationship between race and insomnia. METHODS Participants were recruited from communities in the Detroit metropolitan area and were diagnosed with insomnia disorder using the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition). The final sample included 1,458 individuals. Insomnia symptom severity was assessed via the Insomnia Severity Index and self-reported racial discrimination was evaluated using a single item. Racial discrimination was tested as a mediator in the relationship between race and insomnia symptom severity. Individuals were categroized as either White or a racial minority (i.e., non White individuals), with sensitivity analyses examining Black individuals and non-Black racial minority groups. RESULTS Consistent with our hypothesis, racial discrimination was a significant mediator accounting for 57.3% of the relationship between race and insomnia symptom severity. Sensitivity analyses indicated that the indirect effect of racial discrimination was stronger in the non-Black racial minority group compared to Black individuals. CONCLUSIONS These results provide support that racial discrimination is likely an important mechanism by which racial and ethnic sleep disparities exist. Implications for prevention, intervention, and treatment of insomnia in racial minorities to reduce health disparities are discussed.

Abstract
Over 75% of people with active inflammatory bowel diseases (IBDs) report sleep disturbances, which heighten risk for IBD relapse and flares. Despite mounting evidence for sleep disturbances in IBD, discussion of treatment is severely limited. The most common sleep disturbance, insomnia, occurs in over 50% of adults with chronic health conditions. Herein we describe the gold standard treatment for insomnia, Cognitive Behavioral Therapy for Insomnia (CBT-I). Although yet to be studied in IBD, CBT-I reduces a number of IBD-related comorbidities, including chronic pain, depression, and systemic inflammation. We describe treatment with CBT-I, the impact of CBT-I on these comorbidities, and recommendations for providers.

Abstract
BACKGROUND Sleep disturbance is well established in individuals with obesity, and the relationship between poor sleep and obesity is supported by population, longitudinal, experimental, and intervention studies. However, the prevalence and characteristics of poor sleep in individuals seeking bariatric surgery have thus far been poorly examined. OBJECTIVES We sought to characterize self-reported sleep parameters in individuals seeking bariatric surgery and to compare these data with controls. SETTING Two Academic Medical Centers, United States, and an online survey of healthy controls. METHOD Individuals seeking bariatric surgery (n = 427) completed presurgical psychological evaluations at 2 comprehensive bariatric surgery programs. Data on medical co-morbidities and from self-report questionnaires on sleep quality, insomnia, anxiety, and depression were abstracted from charts. Data from controls (n = 180) were collected using an online survey tool and compared with bariatric cases. RESULTS Across study sites, 40.4% of bariatric cases took at least 30 minutes to fall asleep, 46.7% had insufficient total sleep time (<6.5 hr), 65.1% reported general poor sleep quality, and 30.8% reported clinically significant insomnia symptoms. Approximately 20% of the variance in poor sleep quality and insomnia was explained by body mass index, obstructive sleep apnea, anxiety, and depression. Cases and controls were similar, although bariatric cases reported significantly poorer sleep efficiency. CONCLUSIONS Our results suggest that similar to a control population, the majority of patients seeking bariatric surgery are experiencing sleep difficulties. Presurgical assessment and treatment of sleep problems may be beneficial to patients and may help improve weight loss treatment outcomes. Optimally, assessment would include 1 of the 2 self-report questionnaires used herein, and treatment would involve Cognitive Behavioral Therapy for Insomnia. Future research assessing sleep patterns with objective measurement tools and evaluating the impact of sleep on postsurgical outcomes is warranted.

Abstract
BACKGROUND Although many perinatal women are affected by anxiety, few studies have focused on perinatal anxiety and its potential triggers. The primary aim of this study was to examine concurrent and prospective associations between mid-pregnancy insomnia and perinatal anxiety. Furthermore, we compared psychosocial and reproductive characteristics between participants with and without mid-pregnancy insomnia and explored changes in the prevalence of obsessive-compulsive disorder (OCD) symptoms from mid-pregnancy to 8 weeks postpartum. METHODS This study was part of the Norwegian Depression and Anxiety in the Perinatal Period (DAPP) prospective, population-based, cohort study. We analyzed hospital birth records and questionnaire responses from pregnancy week 17 and postpartum week 8 (n = 530). The Bergen Insomnia Scale was used to measure insomnia and the Hopkins Symptom Checklist to measure anxiety. OCD symptoms were measured based on questions from the Mini-International Neuropsychiatric Interview. RESULTS Mid-pregnancy insomnia was significantly associated with both concurrent and postpartum anxiety in a linear mixed model adjusted for several potential confounders. Participants with mid-pregnancy insomnia had significantly higher levels of perinatal anxiety and postpartum OCD symptoms than participants with normal mid-pregnancy sleep. OCD symptoms affected more women after delivery than before (6.4% vs. 3.8% p = 0.034). LIMITATIONS Immigrants were underrepresented in our sample. CONCLUSION Our results suggest that mid-pregnancy insomnia is a marker for concurrent anxiety and predictor of postpartum anxiety. Future research should examine whether insomnia treatment starting in mid-pregnancy reduces both perinatal insomnia and anxiety. Health providers should also be aware that postpartum women have an increased risk of developing OCD symptoms.

Abstract
OBJECTIVE Self-reported "sleep quality" often is assessed in epidemiologic studies. However, the bases for variation in sleep quality is not fully understood. We quantified the extent to which subjective sleep quality was related to sleep disorders and sleep characteristics among 795 African American adults. METHOD Between 2012 and 2016, participants underwent home sleep apnea testing and 1-week actigraphy (estimating sleep duration, efficiency, fragmentation, latency). Sleep quality, insomnia and restless legs syndrome symptoms, sleepiness, and physician diagnosis of sleep disorders were self-reported. We fit linear regression models to determine the extent to which subjective and objective sleep measures as well as depressive symptoms and anxiety were related to subjective sleep quality. RESULTS After adjustment for covariates, worse sleep quality scores were associated with insomnia and restless legs syndrome symptoms, sleep apnea, physician diagnosis of a sleep disorder, and actigraphy-based fragmented sleep, lower sleep efficiency, and shorter sleep duration. Insomnia symptoms explained the most variance in subjective sleep quality, 21%. Other sleep measures each explained 3% to 7% and psychosocial factors explained 8% to 9% of the variance in subjective sleep quality after adjustment for confounders. CONCLUSIONS The weak associations of sleep quality with sleep disorders and objectively measured sleep disturbances are consistent with concepts of "sleep health" as a multidimensional construct. Sleep quality is a patient-centered outcome that provides unique information over objective measurements of sleep disturbances.

Abstract
BACKGROUND Insomnia and depression are highly prevalent perinatal complications. Ruminating on stress is etiologically implicated in both disorders, and ruminating while trying to fall asleep has been linked to insomnia and depression during pregnancy. Incompatible with rumination is everyday mindfulness, i.e., living with intentional and nonjudgmental awareness of internal and external experiences in the present moment. Responding to stress mindfully may protect against stress-related perinatal complications such as insomnia and depression. The present study described the association between everyday mindfulness and nocturnal rumination, and examined whether these trait characteristics were independently related to perinatal insomnia and depression. METHODS Cross-sectional and secondary analysis of existing data from 65 pregnant women recruited from a multisite hospital in Metro Detroit, MI, USA. Subjects completed online surveys including the Insomnia Severity Index, Edinburgh Postnatal Depression Scale, Presleep Arousal Scale, and the revised Cognitive and Affective Mindfulness Scale. RESULTS Over half (53.8%) of women screened positive for clinical insomnia and 12.3% screened positive for major depression. Women high in mindfulness, relative to those low in mindfulness, reported less nocturnal rumination (Cohen's d=1.16), insomnia symptoms (Cohen's d=1.24), and depressive symptoms (Cohen's d=1.35). Multivariate linear regression revealed that both mindfulness (β=-.24, p=.03) and rumination (β=.38, p<.01) were independently associated with insomnia. Similarly, a multivariate model showed that mindfulness (β=-.41, p<.001) and rumination (β=.35, p<.01) were independently associated with depression. CONCLUSIONS Ruminating in bed at night is strongly associated with insomnia and depression during pregnancy, whereas mindfulness may potentially protect against these stress-related perinatal complications.

Abstract
Sleep is involved in metabolic, emotional and cognitive regulation and is therefore an essential part of our health. Although an association between sleep quality and macronutrient intake has been reported, studies on the effect of macronutrient distribution with sleep quality are limited, and available results are inconsistent. In this study, we aim to assess the association between sleep quality and macronutrient distribution in healthy adults from systematically reviewed cross-sectional studies and randomized controlled trials (RCTs). A total of 19 relevant articles were selected and it was observed that good sleepers (sleep duration ≥ 7 h, global sleep score ≤ 5, sleep latency ≤ 30 min and sleep efficiency >85%) had a higher energy distribution from dietary protein than poor sleepers. On the other hand, good sleepers showed a relatively lower percentage of energy from dietary carbohydrate and fat than poor sleepers. However, meta-regression analysis revealed no dose-dependent association between the macronutrient distributions and sleep duration. These results suggest that consuming a greater proportion of dietary protein may benefit on improving sleep quality in healthy adults. However, findings may be susceptible to reverse causality and additional RCTs are needed.

Abstract
Sleep is an essential physiological process, especially for proper brain function through the formation of new pathways and processing information and cognition. Therefore, when sleep is insufficient, this can result in pathophysiologic conditions. Sleep deficiency is a risk factor for various conditions, including dementia, diabetes, and obesity. Recent studies have shown that there are differences in the prevalence of sleep disorders between genders. Insomnia, the most common type of sleep disorder, has been reported to have a higher incidence in females than in males. However, sex/gender differences in other sleep disorder subtypes are not thoroughly understood. Currently, increasing evidence suggests that gender issues should be considered important when prescribing medicine. Therefore, an investigation of the gender-dependent differences in sleep disorders is required. In this review, we first describe sex/gender differences not only in the prevalence of sleep disorders by category but in the efficacy of sleep medications. In addition, we summarize sex/gender differences in the impact of sleep disorders on incident dementia. This may help understand gender-dependent pathogenesis of sleep disorders and develop therapeutic strategies in men and women.

Insomnia in the Italian Population During Covid-19 Outbreak: A Snapshot on One Major Risk Factor for Depression and Anxiety. Front Psychiatry 2020; 11:579107. [PMID: 33384625 PMCID: PMC7769843 DOI: 10.3389/fpsyt.2020.579107] [Citation(s) in RCA: 47] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Accepted: 11/25/2020] [Indexed: 12/27/2022] Open
Abstract
Objectives: One of the largest clusters of Covid-19 infections was observed in Italy. The population was forced to home confinement, exposing individuals to increased risk for insomnia, which is, in turn, associated with depression and anxiety. Through a cross-sectional online survey targeting all Italian adult population (≥18 yrs), insomnia prevalence and its interactions with relevant factors were investigated. Methods: The survey was distributed from 1st April to 4th May 2020. We collected information on insomnia severity, depression, anxiety, sleep hygiene behaviors, dysfunctional beliefs about sleep, circadian preference, emotion regulation, cognitive flexibility, perceived stress, health habits, self-report of mental disorders, and variables related to individual difference in life changes due to the pandemic's outbreak. Results: The final sample comprised 1,989 persons (38.4 ± 12.8 yrs). Prevalence of clinical insomnia was 18.6%. Results from multivariable linear regression showed that insomnia severity was associated with poor sleep hygiene behaviors [β = 0.11, 95% CI (0.07-0.14)]; dysfunctional beliefs about sleep [β = 0.09, 95% CI (0.08-0.11)]; self-reported mental disorder [β = 2.51, 95% CI (1.8-3.1)]; anxiety [β = 0.33, 95% CI (0.25-0.42)]; and depression [β = 0.24, 95% CI (0.16-0.32)] symptoms. Conclusion: An alarming high prevalence of clinical insomnia was observed. Results suggest that clinical attention should be devoted to problems of insomnia in the Italian population with respect to both prevention and treatment.

Abstract
Alcohol consumption has been suggested as a potential risk factor for diverticular diseases. This study investigated the association between alcohol intoxication or abuse and colonic diverticular disease (CDD).Using the National Health Insurance Research Database of Taiwan from January 1, 2000, to December 31, 2008, 51, 866 subjects newly diagnosed with alcohol intoxication were enrolled in this study as the alcohol intoxication cohort. The control (nonalcohol intoxication) cohort was frequency-matched 1:4 by age, sex and index year. Data were analyzed using a Cox proportional hazards model.The overall incidence of CDD (per 10,000 person-years) for the alcohol intoxication and control cohorts was 16.4 and 3.46, respectively. Compared with patients in the control cohort (95% confidence interval [CI] = 2.76-3.74), those with alcohol intoxication exhibited a 3.21-fold risk of CDD; the risk was particularly higher in male patients (adjusted hazard ratio [aHR] = 3.19, 95% CI = 2.72-3.74) and in those aged <45 years (aHR = 4.95, 95% CI = 3.91-6.27). The alcohol intoxication still had higher risk of CDD than nonalcohol intoxication, regardless of subjects without comorbidity (aHR = 3.38, 95% CI = 2.77-4.11) or with (aHR = 2.85, 95% CI = 2.25-3.61).There was a significant relationship between alcohol intoxication or abuse and CDD.

Adherence to a Dietary Approach to Stop Hypertension (DASH)-Style in Relation to Daytime Sleepiness. Nat Sci Sleep 2020; 12:325-332. [PMID: 32607032 PMCID: PMC7292369 DOI: 10.2147/nss.s246991] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Accepted: 05/27/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND The beneficial impact of adherence to a DASH diet on several metabolic conditions and psychological well-being has been shown previously. Dietary modification can affect sleep quality. Thus, the aim of this present study was to investigate the correlation between adherence to the DASH diet and daytime sleepiness score in adolescent girls. METHODS A total of 535 adolescent girls aged between 12 and 18 years old were recruited from different regions of Khorasan Razavi in northeastern of Iran, using a random cluster sampling method. DASH scores were determined according to the method of Fung et al. A Persian translation of the Epworth Sleepiness Scale (ESS-IR) was used to assess of daytime sleepiness. To investigate the correlation between DASH-style diet and daytime sleepiness score, we applied logistic regression analysis in crude and adjusted models. RESULTS As may be expected, participants with the greatest adherence to the DASH diet had significantly higher intakes of fruits, vegetables, low-fat dairy products, fish and nuts, and lower consumption of refined grains, red and processed meat, sugar-sweetened beverages and sweets. There was an inverse correlation between adherence to the DASH-style diet and scores for daytime sleepiness in crude model (β= -0.12; P=0.005). These findings were remained significant after adjustment for confounding variables (β= -0.08 P=0.04). CONCLUSION There is an inverse correlation between adherence to DASH diet and daytime sleepiness score. Further studies, particularly longitudinal studies, are required to determine whether dietary intervention may improve daytime sleepiness.

Abstract
PURPOSE This review (Part II of a series on sleep disorders) presents an update of the characteristics, epidemiology, assessment, and latest management of insomnia, restless legs syndrome (Willis-Ekbom disease; RLS/WED), and narcolepsy. Insomnia, the most common sleep disorder and most prevalent of all psychological health disorders, is a problem of difficulty initiating and maintaining sleep and early morning awakenings. RLS/WED is characterized by a crawling sensation or urge to move the legs in the evening and nighttime. Narcolepsy is a sleep disorder that commonly results in chronic daytime sleepiness and cataplexy. Nonpharmacological management, which includes education, cognitive behavioral therapy, and complementary therapy, is used as primary or adjunctive to pharmacotherapy for the treatment of these disorders. METHODS This narrative review utilized medical databases such as PubMed to identify relevant English-language original and systematic review articles predominantly from peer-reviewed journals from 2012 to 2019. However, as background, findings from classic articles prior to 2012 were also included. CLINICAL RELEVANCE Assessment of sleep problems, excessive sleepiness, and difficulty performing activities or being productive should be routine in the care of all patients. Utilization of behavioral interventions, including cognitive behavioral therapy, in addition to education and sleep hygiene, can promote sleep quality. Management of insomnia, RLS/WED, and narcolepsy should include helping patients adjust to treatment, managing cataplexy triggers in narcolepsy, and initiating strategies to live with chronic illness to improve quality of life.

Abstract
The high incidence of poor sleep and associated negative health consequences substantiates the need for effective behavioral sleep interventions. We offer an integrative model of sleep disturbance whereby key risk factors for compromised sleep quality and quantity are targeted through mindfulness practice-namely, experiential awareness, attentional control, and acceptance. Theoretical considerations and burgeoning evidence suggest that mindfulness-based interventions (MBIs) may be promising treatments for improving sleep outcomes. However, evidence is mixed due to heterogeneity in design and methods across studies. More rigorous RCTs are needed to determine the efficacy and underlying mechanisms of MBI's for sleep. MBIs that are affordable, accessible, and scalable are needed to improve sleep outcomes at the population level.

Abstract
BACKGROUND The degree to which the relationship between alcohol use and sleeplessness is unidirectional or reciprocal is unclear due to great variation among the results of previous studies. The aim of the present study was to investigate if the relationship between alcohol use and sleeplessness is bidirectional by exploring how the change in and stability of alcohol use were related to sleeplessness, and vice versa, how the change in and stability of sleeplessness were related to alcohol use, in a longitudinal study spanning 13 years. METHOD Data were collected from 9941 adults who participated in two waves (T1: 1994-1995, and T2: 2007-2008) of the Tromsø Study, a Norwegian general population health study. Alcohol use was measured by questions asking about the frequency of drinking, amounts of alcohol normally consumed and the frequency of binge drinking, whereas sleeplessness was measured by one item asking about the frequency of experiencing sleeplessness. Variables representing change in and stability of consumption of alcohol and sleeplessness from T1 to T2 were created. Logistic regression analyses, stratified by gender, were used to analyze the data. RESULTS Men reporting stable high (OR = 2.11, p. < .001) or increasing (OR = 1.94, p. < .01) consumption of alcohol from T1 to T2 had a significantly higher risk of reporting sleeplessness at T2. Likewise, men experiencing stable (OR = 1.84, p. < .01) or increasing (OR = 1.78, p. < .001) sleeplessness from T1 to T2 had a significantly higher risk of reporting high consumption of alcohol at T2. No significant effects were detected among women. CONCLUSION The findings indicate a bidirectional relationship between high consumption of alcohol and sleeplessness only among men. Thus, healthcare professionals ought to be informed about the health risks associated with excessive drinking and struggling with sleeplessness, especially in men.

Abstract
STUDY OBJECTIVES To estimate the prevalence of insomnia disorder among older veterans and to study relationships among age and self-rated health, with insomnia disorder, self-reported sleep duration and sleep efficiency. METHODS A cross-sectional postal survey of community-dwelling older veterans (older than 60 years) seen at one VA Healthcare System in the prior 18 months was performed, which was constructed to align with the general diagnostic criteria for insomnia disorder (International Classification of Sleep Disorders, Second Edition [ICSD-2]). The survey also queried self-reported sleep duration, bedtime, and wake time, which were used to calculate sleep efficiency. The survey also asked about race/ethnicity and self-rated health (using the general health item from the Short Form-36). RESULTS A completed survey was returned by 4,717 individuals (51.9% response rate; mean age 74.1 years). Of those, 2,249 (47.7%) met ICSD-2 diagnostic criteria for insomnia disorder. In logistic regression analyses, insomnia disorder was more likely among younger age categories (odds ratios [OR] 1.4-2.5) and in those with worse self-rated health (OR 2.1-14.4). Both total nocturnal sleep time and time in bed increased with older age (all P < .001), whereas sleep efficiency did not differ. Worse self-rated health was associated with shorter total nocturnal sleep time, more time in bed, and lower (worse) sleep efficiency. CONCLUSIONS Results of the postal survey suggest that almost half of community-dwelling older veterans have insomnia disorder, which was more common in young-old and among those with worse self-rated health. Additional work is needed to address the high burden of insomnia among older adults, including those with poor health.

Abstract
Differences in sleep for men and women begin at a very early age, with women reporting poorer sleep and having a higher risk for insomnia compared with men. Women are particularly vulnerable to developing insomnia during times of reproductive hormonal change. Sleep across the woman's lifespan and special treatment considerations for using cognitive behavioral therapy for insomnia (CBT-I) in women will be addressed in this review.

Abstract
STUDY OBJECTIVES While anxiety rates are alarmingly high in short sleeping insomniacs, the relationship between insomnia and anxiety symptoms has not been extensively studied, especially in comparison to the relationship between insomnia and depressive symptoms. Using residency training as a naturalistic stress exposure, we prospectively assessed the role of sleep disturbance and duration on anxiety-risk in response to stress. METHODS Web-based survey data from 1336 first-year training physicians (interns) prior to and then quarterly across medical internship. Using mixed effects modeling, we examined how pre-internship sleep disturbance and internship sleep duration predicted symptoms of anxiety, using an established tool for quantifying symptom severity in generalized anxiety disorder (GAD). RESULTS Pre-internship poor sleepers are at more than twice the odds of having short sleep (≤6 h) during internship as good sleepers (OR = 2.38, 95% CI = 1.61, 3.57). Poor sleepers were also at twice the odds for screening positive for probable GAD diagnosis (OR = 2.08, 95% CI = 1.26, 3.45). Notably, sleep onset insomnia strongly predicted anxiety development under stress (OR = 3.55, 95% CI = 1.49, 8.45). During internship, short sleep associated with concurrent anxiety symptoms (b = -0.26, 95% CI = -0.38, -0.14) and predicted future anxiety symptoms even more strongly (b = -0.39, 95% CI = -0.76, -0.03). CONCLUSIONS Poor sleepers, particularly those with sleep onset insomnia symptoms, are vulnerable to short sleep and GAD anxiety and worry during chronic stress.

Abstract
Insomnia symptoms are highly prevalent and associated with several adverse medical conditions, but only few determinants, including non-modifiable ones, have been highlighted. We investigated associations between body silhouette trajectories over the lifespan and insomnia symptoms in adulthood. From a community-based study, 7 496 men and women aged 50–75 years recalled their body silhouette at age 8, 15, 25, 35 and 45, and rated the frequency of insomnia symptoms on a standardized sleep questionnaire. An Epworth Sleepiness Scale ≥11 defined excessive daytime sleepiness (EDS). Using a group-based trajectory modeling, we identified five body silhouette trajectories: a ‘lean-stable’ (32.7%), a ‘heavy-stable’ (8.1%), a ‘moderate-stable’ (32.5%), a ‘lean-increase’ (11%) and a ‘lean-marked increase’ (15.7%) trajectory. In multivariate logistic regression, compared to the ‘lean-stable’ trajectory, the ‘lean-marked increase’ and ‘heavy-stable’ trajectories were associated with a significant increased odd of having ≥1 insomnia symptoms as compared to none and of having a proxy for insomnia disorder (≥1 insomnia symptom and EDS). The association with the ‘lean-marked increase' trajectory’ was independent from body mass index measured at study recruitment. In conclusion, increasing body silhouette over the lifespan is associated with insomnia symptoms in adulthood, emphasizing the importance of weight gain prevention during the entire lifespan.

Abstract
PURPOSE This study aimed to investigate the prevalence of sleeping problems in prostate cancer survivors and to explore the role of predisposing, precipitating and perpetuating factors in this process. METHODS Using a cross-sectional design, 3348 prostate cancer survivors between 2 and 18 years post diagnosis reported experiences of insomnia using the QLQC30, along with their sociodemographic characteristics, health status and treatment(s) received. The EQ5D-5L and QLQPR25 assessed survivors' overall and prostate cancer-specific health-related quality of life. A hierarchical multiple regression analysis was constructed with three blocks: (1) predisposing (e.g. demographics at diagnosis), (2) precipitating (e.g. disease extent, treatment) and (3) perpetuating factors (e.g. side effects). RESULTS Nineteen percent of survivors reported significant problems sleeping. The final model accounted for 31% of the variance in insomnia scores (p < .001). In order of magnitude, associates of sleep disturbance were urinary symptoms (β = 0.22; p < .001), experiencing symptoms of depression/anxiety (β = 0.18; p < .001), hormone treatment-related symptoms (β = 0.12; p = .001), pain (β = 0.10; p < .001) and bowel symptoms (β = 0.06; p = .005). Having a lower education and more comorbidities at diagnosis also predicted sleep problems. CONCLUSION Results suggest that it is the ongoing adverse effects of prostate cancer and its treatment (e.g. urinary symptoms) that put survivors most at risk of sleep problems. Strong associations with symptoms of depression/anxiety were also observed. Findings highlight the need for health care practitioners to treat and manage adverse effects of prostate cancer treatment in order to mitigate sleep disturbance in survivors.

Abstract
BACKGROUND Sleep disorder after total knee arthroplasty (TKA) is complex as it greatly differs from patient to patient. Thus, it can be seen that we should further know the detail in sleep disorders following TKA to find well solutions to achieve satisfactory sleep and better recovery. METHODS Between October 2011 and January 2016, 965 patients accepted primary TKA. We reviewed each patient's data. Sleep disorder was evaluated via subjective instruments. The Sleep Questionnaire in the present study is a 12-item instrument that evaluates sleep in terms of three dimensions: sleep quality; disruptive factors; and specific forms. Patients were identified and confirmed as at least 1 kind of sleep disorders according to the Second Edition of the International Classification of Sleep Disorders (ICSD-2). And we compare the clinical characteristics and difference in postoperative recovery of different types of sleep disorders. RESULTS Sleep disturbances persisted approximately 2 months postoperatively. 75.9% patients was classified into primary insomnias, while 24.1% was secondary insomnias. There was the largest number of those who were adjustment sleep disorder. Pains, mental elements, and factors intrinsic to the patients were the most significant causes of insomnia of patients. There were significant differences in VAS pain score (P < 0.001*), active ROM (P < 0.001*) and LOS in hospital (P < 0.001*) among varied forms of insomnias. CONCLUSIONS Our data revealed that adjustment insomnia ranked first. Specifically, the factors affecting sleep quality postoperatively included pains, mental elements, and factors intrinsic to the patients etc. In addition, we found that patients with difficulty in staying asleep and non-restorative sleep has increased pain scores and LOS in hospital with decreased active ROM in comparison to difficulty in falling asleep and too early awakening. Our data may be of a certain benefit to rational use of medication to improve diverse insomnias and to make patients recover better.

Abstract
Background Insomnia is one of the main symptoms of sleep disorders. Previous studies have suggested that alcohol intake is associated with several adverse health outcomes. The association between alcohol consumption and insomnia has been addressed in several studies with different results. However, whether gender may modify the association between alcohol consumption and insomnia is not clear. This study will focus on gender differences in the relationship between alcohol consumption and insomnia. Methods The final study includes 8081 subjects aged between 18 and 65 years from the Jidong cohort. The data on alcohol consumption is collected by questionnaires, and insomnia problems are assessed using the entire 8-item Athens Insomnia Scale (AIS-8). Logistic analysis is used to evaluate the association between alcohol consumption and insomnia. Results Among the 8081 participants in this study, 2618 (32.4%) are alcohol drinkers, including 2424 males and 194 females. The prevalence of insomnia is 9.6% in the male and 10.6% in the female. The adjusted odds ratios (ORs) with 95% confidence interval (CI) of mild-to-moderate drinkers and heavy drinkers for insomnia are 1.27 (1.02–1.58) and 1.02 (0.79–1.32), respectively. Heavy alcohol consumption is significantly correlated with insomnia in the female, after controlling for potential confounding factors (OR: 2.11, 95% CI: 1.28–3.49, p for interaction = 0.002). Conclusion A significant association between alcohol consumption and insomnia is found in females, but not in males from the northern Chinese population.

Abstract
Sleep reactivity is the trait-like degree to which stress exposure disrupts sleep, resulting in difficulty falling and staying asleep. Individuals with highly reactive sleep systems experience drastic deterioration of sleep when stressed, whereas those with low sleep reactivity proceed largely unperturbed during stress. Research shows that genetics, familial history of insomnia, female gender and environmental stress influence how the sleep system responds to stress. Further work has identified neurobiological underpinnings for sleep reactivity involving disrupted cortical networks and dysregulation in the autonomic nervous system and hypothalamic-pituitary-adrenal axis. Sleep reactivity is most pathologically and clinically pertinent when in excess, such that high sleep reactivity predicts risk for future insomnia disorder, with early evidence suggesting high sleep reactivity corresponds to severe insomnia phenotypes (sleep onset insomnia and short sleep insomnia). High sleep reactivity is also linked to risk of shift-work disorder, depression and anxiety. Importantly, stress-related worry and rumination may exploit sensitive sleep systems, thereby augmenting the pathogenicity of sleep reactivity. With the development of cost-effective assessment of sleep reactivity, we can now identify individuals at risk of future insomnia, shift-work disorder and mental illness, thus identifying a target population for preventive intervention. Given that insomniacs with high sleep reactivity tend to present with severe insomnia phenotypes, patient sleep reactivity may inform triaging to different levels of treatment. Future research on sleep reactivity is needed to clarify its neurobiology, characterize its long-term prospective associations with insomnia and shift-work disorder phenotypes, and establish its prognostic value for mental illness and other non-sleep disorders.

Abstract
The prevalence of chronic insomnia is on the rise among young, middle-aged, and older adults. This secondary data analysis examined age-group differences in the experience of and factors perpetuating insomnia severity. Pretest data, obtained from a trial of behavioral interventions, were collected from 742 participants, using psychometrically sound measures of perpetuating factors (sleep habits, unhelpful beliefs, presleep arousal), insomnia experience (symptoms, perceived severity), and consequences or impact on daytime functioning. The age groups reported different insomnia symptoms (difficulty maintaining sleep in older adults) and impact on daytime functioning (poorer in older adults), but the same level of perceived insomnia severity. Unhelpful beliefs about sleep predicted insomnia severity in all age groups, and presleep arousal contributed to insomnia in young adults. The results highlight the importance of adequately managing chronic insomnia to minimize its impact on daytime functioning in all age groups, and of tailoring therapy to their experiences.

Abstract
Insomnia is a prevalent sleep disorder that is associated with a multitude of health consequences. Particularly, insomnia has been associated with cardiovascular disease and its precursors, such as hypertension and blood pressure (BP) non-dipping. The present systematic review aimed to summarize the evidence on the concurrent and prospective associations between insomnia and hypertension and/or BP. Using electronic search engines (PubMed, SCOPUS, PsycINFO), 5,618 articles published from January 1970 to December 2017 were identified, and 64 met the inclusion criteria (26 to 162,121 participants; age range: 18-100; 46.4% male). Insomnia was based on diagnostic or non-diagnostic criteria. Hypertension was based on self-or physician-reports, antihypertensive medication use, and/or measured BP. Findings indicate that when insomnia is frequent, chronic, and/or accompanied with short sleep duration or objective markers of arousal, there is a strong association with hypertension/BP. Based on limited studies, hypertension did not significantly predict future insomnia in middle-aged adults, but did in older adults. Based on a majority of case-control studies, no differences in BP were found between participants with and without insomnia. Further research is needed to identify putative pathophysiological mechanisms underlying the link between insomnia and hypertension. The impact of insomnia therapy on BP should also be further examined in the future.

Abstract
Hyperarousal is a key component in all modern etiological models of insomnia disorder. Overall patterns in the literature suggest that over-active neurobiological and psychological systems contribute to difficulty sleeping. Even so, mixed results regarding the specific mechanisms linking hyperarousal to sleep disturbance limit current etiological conceptualizations. Similar basal arousal profiles between individuals with high vs low risk for insomnia in the absence of stress exposure suggest that dysregulated stress "response" rather than general hyperarousal may be a more pertinent marker of risk. In this report, we discuss evidence for hyperarousal in insomnia and explore the role of sleep reactivity. A trait characteristic, sleep reactivity is the degree to which stress disrupts sleep, manifesting as difficulty falling and staying asleep. Premorbid sleep reactivity has been shown to identify individuals at risk for future insomnia disorder, such as highly reactive sleepers (whose sleep systems are sensitive to stress) who are at elevated disease risk. Research points to genetics, family history of insomnia, gender, and environmental stress as factors that influence sleep reactivity. Importantly, stress-related cognitive-emotional reactivity (e.g., rumination, worry) may exploit the vulnerability of a highly reactive sleep system. We propose that sleep reactivity and cognitive-emotional reactivity may share a bidirectional relationship, conferring an insalubrious environment for sleep in response to stress. Future research on sleep reactivity is needed to identify its neurobiology, characterize its relationship with cognitive-emotional reactivity, and explore the potential clinical utility of sleep reactivity in treatment planning.

Abstract
Introduction Sleep disturbance is a major public health issue and is comorbid with the cluster of conditions associated with metabolic syndrome (MetS). Our study explored the presence of sleep disturbance, including daytime sleepiness, the risk for obstructive sleep apnea (OSA), and insomnia symptoms, in a cohort of adult Black men and women with MetS. Methods Patients (n=1,013) from the Metabolic Syndrome Outcome Study (MetSO), 2009-2012, met criteria for MetS based on guidelines from the National Cholesterol Education Program's Adult Treatment Panel and provided sociodemographic data and the Apnea Risk Evaluation System (ARES) questionnaire to assess OSA risk, sleep characteristics, and physician-reported diagnosis of a sleep disorder. Results Prevalence of the components of MetS included: diabetes (60%); obesity (67%); hypertension (94%); and dyslipidemia (74%). Based on the ARES, 49% were at risk for OSA. Of all study patients, slightly more than half (53%) reported feeling sleepy during the day, and 10% reported an insomnia diagnosis. The most common sleep disturbance reported by 46% of the patients was early morning awakenings (EMA). This was closely followed by 42% who reported difficulty staying asleep (DSA) and 38% reporting difficulty falling asleep (DFA). Seventy percent reported short sleep (≤ 6 hours), whereas a minority (19%) reported long sleep (≥ 9 hours). Only 12% used sleep aids. Women, compared with men, reported greater daytime sleepiness, greater DFA, and greater DSA (57% vs 45%; 41% vs 32.4%; 45% vs 37%), respectively. Conclusion Blacks with MetS reported insomnia symptoms and insomnia disorder, use of sleep aids, feeling sleepy during the day, and inadequate sleep durations. The presence of these sleep characteristics suggests that patients with MetS should be referred for further sleep assessment.

Abstract
OBJECTIVE AND BACKGROUND Over the past few years, the comprehensive models of insomnia have exhibited impressive developments. However, there is scarce knowledge on predisposing or vulnerability factors for insomnia. One of the most promising constructs to aid in filling this gap is stress-induced sleep reactivity assessed through self-report. Our aim was to study the psychometric properties of the European Portuguese version of the Ford Insomnia Response to Stress Test (FIRST). PARTICIPANTS We recruited a large sample of students attending medical school (N = 699). METHODS Several analyses were carried out such as internal consistency, construct validity, and discriminant groups' analysis. RESULTS It was observed that FIRST-PT shows good internal consistency (Cronbach´s alpha = .81) and validity indicators. Interestingly, and contrary to what was observed in the previously published studies on psychometric properties of the FIRST, it was observed that a two-factor solution (Factor I = rumination, Factor II = worry) was the most adequate one to explain the correlation matrix, accounting for approximately 44% of the total variance. CONCLUSIONS The FIRST-PT proved to be a useful and reliable tool to measure stress-induced sleep reactivity. However, these results should be replicated in other groups, particularly clinical samples, in order to verify the stability of its factorial dimension.

Abstract
Understanding the underlying mechanisms of recovery from insomnia is an important goal for improving existing treatments. In a randomised controlled trial, 57 participants with insomnia disorder were given either cognitive therapy (CT) or mindfulness-based therapy (MBT) following 4 sessions of CBT. Each participant was assessed on process measures related to CT and MBT. MBT resulted in improvement on mindfulness process measures and the size of the improvement was significantly greater than achieved in the CT condition. Interestingly, CT and MBT both resulted in significant improvement on the cognitive process measures. Treatment outcome on the primary outcome measure (Insomnia Severity Index) was not predicted by type of treatment but was predicted by posttreatment scores on the cognitive process measures. The results suggest that changes in cognitive processes are especially important in treating insomnia, and that there are different therapeutic modalities through which this can be achieved.

Abstract
BACKGROUND Alongside obesity, insomnia and depression are common public health problems. Sleep problems are currently believed to be associated with excessive food intake and metabolic disturbances. Therefore, we aimed to explore a relationship between insomnia, depressive symptoms and eating habits as well as metabolic parameters in bariatric surgery candidates. METHODS A total of 361 unrelated obese subjects were included in this study. Severity of sleep problems was measured with Athens Insomnia Scale (AIS) and the severity of depressive symptoms was assessed with the Beck Depression Inventory (BDI-II). Obstructive sleep apnea (OSA) was assessed by the Apnea Hypopnoea Index (AHI). Information was obtained about demographics, eating habits and lifestyle. Blood samples were collected to measure concentration of lipids (cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol), and glucose. RESULTS The median (interquartile range) score for AIS in the study participants was 5 (3-8) with a range of 0-24 and 47% (171) participants scored ≥6 (met criteria for diagnosis of insomnia). Statistically significant correlations were found between the AIS scores and serum triglycerides and glucose concentrations, and BDI-II total scores. The highest scores on AIS and BDI-II were found in participants with high frequency of snack food consumption, in physically inactive individuals as well as in those who self-reported eating at night or who declared more than 3 intense emotions associated with a desire-to-eat. Adjusted multivariate logistic regression analysis revealed that clinical insomnia was most strongly associated with daily consumption of snack foods, with the odds ratio of 3.26 (95% CI: 1.74-6.11), while depressive symptoms were strongly associated with both eating in response to ≥3 specific emotions with OR = 2.93 (95% CI: 1.26-6.78) as well as with daily consumption of snack foods with OR = 2.87 (95% CI: 1.16-5.14). CONCLUSIONS The results indicate that insomnia and depression in obese individuals are associated with eating habits, and suggest that in some patients these associations appears as major factors affecting obesity development.

Abstract
PURPOSE OF REVIEW Sleep plays many roles in maintenance of cardiovascular health. This review summarizes the literature across several areas of sleep and sleep disorders in relation to cardiometabolic disease risk factors. RECENT FINDINGS Insufficient sleep duration is prevalent in the population and is associated with weight gain and obesity, inflammation, cardiovascular disease, diabetes, and mortality. Insomnia is also highly present and represents an important risk factor for cardiovascular disease, especially when accompanied by short sleep duration. Sleep apnea is a well-characterized risk factor for cardiometabolic disease and cardiovascular mortality. Other issues are relevant as well. For example, sleep disorders in pediatric populations may convey cardiovascular risks. Also, sleep may play an important role in cardiovascular health disparities. SUMMARY Sleep and sleep disorders are implicated in cardiometabolic disease risk. This review addresses these and other issues, concluding with recommendations for research and clinical practice.
