Relapse insomnia increases greater risk of anxiety and depression: evidence from a population-based 4-year cohort study

ObjectiveWe investigated the longitudinal impacts of insomnia on the subsequent developments of anxiety and depression during a four-year follow-up. We further categorized individuals with insomnia into different insomnia subgroups to examine whether the risk of anxiety and depression varies by subtype.MethodsParticipants were identified from National Health Insurance enrollees in Taiwan during 2002–2009. The study included 19,273 subjects with insomnia and 38,546 matched subjects without insomnia. All subjects did not have previous diagnosis of insomnia, sleep apnea, anxiety, or depression.ResultsCompared with non-insomniacs, insomniacs had a higher risk of developing anxiety only [adjusted hazard ratio (HR) = 8.83, 95% CI = 7.59–10.27], depression only (adjusted HR = 8.48, 95% CI = 6.92–10.39), and both anxiety and depression (adjusted HR = 17.98, 95% CI = 12.65–25.56). When breaking down the insomnia subgroups, individuals with a relapse of insomnia (adjusted HR = 10.42–26.80) had the highest risk of anxiety only, depression only, and both anxiety and depression, followed by persistent insomnia (adjusted HR = 9.82–18.98), then remitted insomnia (adjusted HR = 4.50–8.27). All three insomnia subgroups had a greater four-year cumulative incidence rate than the non-insomnia group for anxiety only, depression only, and both anxiety and depression (p < 0.0001).ConclusionOur findings reinforce the clinical predictor role of insomnia in the future onset of anxiety or/and depression. Awareness of insomnia and treatment of insomnia should be recommended at clinics, and patterns of insomnia should be monitored to help treatment and control of subsequent psychiatric disorders. Future research with comprehensive data collection is needed to identify factors that contribute to different insomnia subtypes.     

The association of insomnia with anxiety disorders and depression: exploration of the direction of risk

The purpose of this study is to explore the direction of the association between insomnia and anxiety disorders and major depression among a community-based sample of adolescents to better understand their potential etiologic relationships. Data come from a community-based sample of 1014 youth aged 13–16. Structured interviews were conducted to assess DSM-IV diagnoses. Retrospectively reported ages of onset were used in Proportional Hazards models to estimate increased risk of one disorder associated with prior onset of the others. The lifetime associations of DSM-IV insomnia with each anxiety disorder and with depression were moderate (OR = 3.2–6.8). Among those with comorbid disorders, anxiety disorders preceded insomnia 73% of the time, while insomnia occurred first in 69% of comorbid insomnia and depression cases. Any prior anxiety disorder was associated with an increased risk of insomnia adjusting for gender, race/ethnicity, and depression prior to insomnia (HR = 3.5). However, prior insomnia was not significantly associated with onset of anxiety disorders. Prior depression was not associated with onset of insomnia, but prior insomnia was associated with onset of depression adjusting for gender, race/ethnicity, and any prior anxiety disorder (HR = 3.8). These results suggest distinct natural courses of development between DSM-IV insomnia, anxiety, and depression during adolescence. Additionally insomnia may have independent, and potentially etiologically distinct, directional associations with anxiety disorders versus depression.     

Sleep duration,insomnia, and markers of systemic inflammation: Results from the Netherlands Study of Depression and Anxiety (NESDA)

Systemic inflammation has emerged as a potential pathway linking depressive and anxiety disorders with disease risk. Short and long sleep duration, as well as insomnia, are common among psychiatric populations and have previously been related to increased inflammation. The aim of the present study was to investigate associations between sleep duration and insomnia with biomarkers of inflammation and to explore whether these associations varied by psychiatric diagnostic status. To this end, self-reported measures of sleep duration, insomnia symptoms, and markers of inflammation, including C-reactive protein (CRP), interleukin-(IL)-6, and tumor necrosis factor (TNF)-α, were obtained in 2553 adults (aged 18–65 years) diagnosed with current/recent or remitted depressive and/or anxiety disorders and healthy controls enrolled in the Netherlands Study of Depression and Anxiety (NESDA). Regression analyses revealed associations between sleep duration and levels of CRP and IL-6 with higher levels observed in long sleepers. These associations remained statistically significant after controlling for age, gender, education, body mass index, smoking, alcohol consumption, medical comorbidities, medication use, psychotropic medication use, and psychiatric diagnostic status. There were no clear associations between insomnia symptoms and levels of inflammation. Relationships between sleep duration and inflammation did not vary as a function of psychiatric diagnostic status. These findings suggest that elevated levels of systemic inflammation may represent a mechanism linking long sleep duration and disease risk among those with and without depressive and anxiety disorders.     

Cross-sectional survey following a longitudinal study on mental health and insomnia of people with sporadic COVID-19

BACKGROUNDIn the post-pandemic era, the emergence of sporadic cases of coronavirus disease 2019 (COVID-19) and the scale of the pandemic are unpredictable. Therefore, the impact of sporadic cases of COVID-19 and isolation measures on mental health and sleep in different groups of people need to be analyzed. AIMTo clarify the severity of psychological problems and insomnia of staff and community residents around a hospital with sporadic cases of COVID-19, and their relationship with quarantine location and long-term changes.METHODSA cross-sectional survey was conducted on community residents and medical staff. Many of these medical staff had been subjected to different places of quarantine. Community residents did not experience quarantine. Hospital anxiety and depression scale (HADS), acute stress disorder scale (ASDS) and insomnia severity index (ISI) were used to evaluate anxiety and depression, acute stress disorder symptoms, and the severity of insomnia. Additionally, we conducted a 1-year follow-up study on medical staff, with related scales measurement immediately after and one year after the 2-wk quarantine period.RESULTSWe included 406 medical staff and 226 community residents. The total scores of ISI and subscale in HADS of community residents were significantly higher than that of medical staff. Further analysis of medical staff who experienced quarantine showed that 134 were quarantined in hotels, 70 in hospitals and 48 at home. Among all subjects, the proportions of HADS, ASDS and ISI scores above normal cutoff value were 51.94%, 19.17% and 31.11%, respectively. Multivariable logistic regression analysis found that subjects with higher total ASDS scores had a greater risk to develop anxiety and depression. The total ISI score for medical staff in hotel quarantine was significantly higher than those in home quarantine. Total 199 doctors and nurses who completed the 1-year follow-up study. Compared with baseline, HADS and ASDS scores decreased significantly one year after the end of quarantine, while ISI scores did not change significantly. CONCLUSIONSporadic COVID-19 cases had a greater psychological impact on residents in surrounding communities, mainly manifested as insomnia and depressive symptoms. Hotel quarantine aggravated the severity of insomnia in medical staff, whose symptoms lasted ≥ 1 year.     

A bidirectional relationship between anxiety and depression, and insomnia? A prospective study in the general population

OBJECTIVE: The purpose of this study was to examine whether there is a bidirectional relationship between, on one hand, anxiety and depression and, on the other hand, insomnia over the course of a year. METHODS: A randomly selected sample of 3000 participants from the general population filled out a baseline survey (N=1812) and a 1-year follow-up survey (N=1498) on anxiety, depression, and insomnia. RESULTS: On cross-sectional analyses, bivariate correlations showed that anxiety, depression, and insomnia were significantly intercorrelated (varphi=.31-.54). On prospective analyses, logistic regression analyses demonstrated that anxiety at baseline [odds ratio (OR)=4.27 (8% of variance)] and depression at baseline [OR=2.28 (2% of variance)] were related to new cases of insomnia on follow-up. Furthermore, insomnia at baseline was related to new episodes of high anxiety and high depression on follow-up [OR=2.30 (2% of variance) and OR=3.51 (4% of variance), respectively]. CONCLUSION: Evidence suggests that there is a bidirectional relationship between, on one hand, anxiety and depression and, on the other hand, insomnia. This suggests that anxiety, depression, and insomnia are intertwined over time, implying implications for theoretical conceptualizations and interventions.

目的 调查在新冠肺炎疫情常态化防控下社区居民的心理健康状况并分析其相关因素。方法 本研究为横断面调查,采用滚雪球抽样法,于2020年8月28日-9月7日通过问卷星网络平台向居民发放调查问卷。采用患者健康问卷抑郁量表（PHQ-9）、广泛性焦虑量表（GAD-7）、失眠严重程度指数量表（ISI）及中文版知觉压力量表（CPSS）评估居民的心理健康状况。结果 476名居民抑郁、焦虑、失眠及高水平压力症状检出率分别为32.35%、21.22%、24.58%及48.74%。男性高水平压力症状检出率高于女性（χ²=5.269）,未婚、离异或丧偶居民的抑郁及焦虑症状检出率均高于已婚居民（χ²=5.251、8.851）,有心理服务需求的居民抑郁、焦虑、失眠及高水平压力症状检出率均高于无此需求的居民（χ²=46.316、66.934、20.153、21.576）,差异均有统计学意义（P<0.05或0.01）。相关分析显示,社区居民年龄与CPSS评分呈负相关（r=-0.171,P<0.01）,睡眠时间与PHQ-9、GAD-7及ISI评分均呈负相关（r=-0.210、-0.247、-0.297,P均<0.01）,关注疫情信息时长与ISI评分呈负相关（r=-0.097,P<0.05）。结论 在疫情常态化防控下,居民的抑郁、焦虑、失眠及高水平压力症状仍较常见。男性和年轻居民更有可能出现高水平压力症状,睡眠时间短和有心理服务需求的居民更有可能出现抑郁、焦虑及失眠症状,关注疫情信息时长越短越有可能出现失眠症状。     

Nocturnal awakenings and comorbid disorders in the American general population

Objective

Nocturnal awakenings are one of the most prevalent sleep disturbances in the general population. However, little is know about how its severity affects co-morbidity with mental disorders and organic diseases.

Methods

A representative sample consisting of 8937 non-institutionalized individuals aged 18 or over living in Texas, New York and California states were interviewed by telephone. The interviews included sleeping habits, health, sleep and mental disorders. Nocturnal awakenings were evaluated according to their frequency per week and per night, their duration and the motive(s) for the awakenings.

Results

A total of 35.5% of the sample reported awakening at least 3 nights per week: 23% of reported awakening at least one time every night; 4.5% 5 or 6 nights per week and 7.9% 3 or 4 nights per week. Nocturnal awakenings increased with age only among people with nightly awakenings and were more frequent among women than men only among those awakening every night. More than 90% of subjects reported this problem lasted for more than 6 months. About 40% of subjects with nocturnal awakenings also reported other insomnia symptoms. Generally speaking, organic diseases and psychiatric disorders were more frequent among subjects waking up at least 3 nights per week regardless the frequency of nocturnal awakenings. However, nightly nocturnal awakenings were associated with more frequent organic diseases, obesity and psychiatric disorders.

Conclusions

Nocturnal awakenings disrupt the sleep of about one third of the general population. Nocturnal awakenings are associated with a wide variety of organic diseases and psychiatric disorders that warrant appropriate treatment.     

Effect of COVID-19 on mental health among the young population in Lebanon

BackgroundCOVID-19 is a global pandemic that has raised worldwide public health concerns. The wide spread of the virus has led to unprecedented disturbance to regular life for people around the globe and impacted their mental health.AimsThe aims of the current study were to investigate the prevalence of psychiatric symptoms related to insomnia, depression, and anxiety, and identify risk factors contributing to psychological stress in Lebanese young population during COVID-19 pandemic.MethodA cross-sectional study was done on the Lebanese young population. Participants were 4397 males and females aged 18 to 35 years who filled a self-administered online questionnaire. Three validated scales were used to measure the mental health status of the participants during the COVID-19 pandemic: 7-item Insomnia Severity Index for insomnia, the Patient Health Questionnaire 9-item depression module for depression, and the 7-item Generalized Anxiety Disorder scale for anxiety.ResultsThe median interquartile range scores for anxiety, insomnia, and depression, were 8 (4–13), 10 (5–14), and 9 (5–12) respectively. Higher anxiety scores were reported with female gender (P < 0.001) and alcohol usage (P = 0.04). Moderate to severe insomnia was associated with single (P = 0.02) and divorced marital status (P = 0.003), university education (P < 0.001), consumption of caffeinated beverages (P = 0.02) and energy drinks (P = 0.03). Higher depression scores were associated with status of being the only person working at home (P = 0.01), family income more than 500 USD (P = 0.008), multiple insurance plans (P = 0.01), and contact with a confirmed COVID-19 case (P = 0.01).ConclusionsThe findings of this study demonstrate the considerable impact of COVID-19 pandemic and lockdown on Lebanese young population's mental status such as anxiety, depression and insomnia. Further follow-up studies are warranted to assess the long-term mental effects that can be imposed by the pandemic.     

The associations of insomnia symptoms and chronotype with daytime sleepiness,mood symptoms and suicide risk in adolescents

ObjectivesTo investigate the association of insomnia and chronotype preference with daytime impairment and psychopathology in a community sample of adolescents in Hong Kong.MethodsThis was a cross-sectional study that included seven local secondary schools in Hong Kong. A total of 1667 adolescents (mean age: 14.8 ± 1.6 years old; boys: 56.5%) returned a battery of self-report questionnaires including Insomnia Severity Index (ISI) and reduced Horne and Östberg Morningness and Eveningness Questionnaire (rMEQ) for assessing insomnia symptoms and chronotype preference, respectively. A subset of adolescent samples (n = 768) were additionally assessed for suicidal ideation. Potential confounders including age, gender and sleep duration were controlled for in the analyses.ResultsThe prevalence of insomnia symptoms and eveningness chronotype was 37% and 25.6%, respectively. Regression models indicated that insomnia and eveningness were independently associated with excessive daytime sleepiness (insomnia: adjusted OR [AdjOR] = 3.8; 95% confidence interval [C.I.] = 2.9–5.0; eveningness: AdjOR = 2.6; 95% C.I. = 1.9–3.7), and an increased risk of depression (insomnia: AdjOR = 3.5, 95% C.I. = 2.5–5.0; eveningness: AdjOR = 2.0, 95% C.I. = 1.3–3.2). The odds ratio increased to 8.7 (95% C.I. = 6.1–12.3, p < 0.001) for excessive daytime sleepiness and 4.8 (95% C.I. = 3.2–7.2, p < 0.001) for depression among adolescents with both insomnia and eveningness. Insomnia symptoms, but not eveningness, were associated with anxiety symptoms (AdjOR = 5.8; 95% C.I. = 3.6–9.4) and suicidal ideation (AdjOR = 2.1, 95% C.I. = 1.4–3.2).ConclusionsThe present study provided further evidence that insomnia and eveningness uniquely contributed to poor daytime functioning and mood related outcomes, while the co-existence of these two conditions could confer a greater risk in adolescents. However, insomnia, but not eveningness, was significantly linked to suicidality after controlling for mood symptoms. Our findings highlighted the necessity of timely management of sleep and circadian issues in adolescents.

Sleep disturbances and reduced work functioning in depressive or anxiety disorders

Objectives

We aimed to examine the associations between sleep disturbances and work functioning in an epidemiologic cohort study in subjects with or without depressive or anxiety disorders.

Methods

There were 707 subjects included in our analyses with depressive or anxiety disorders and 728 subjects without current depressive or anxiety disorders. Insomnia was defined as a score ?9 using the Insomnia Rating Scale. Self-reported sleep duration was categorized in short, normal, and long (?6, 7–9, and ?10 h, respectively). Work absenteeism was defined as none, short (?2 weeks), or long (>2 weeks). Work performance was defined as not impaired, reduced, or impaired. Logistic regression analyses were performed to examine the associations of sleep disturbances with work functioning.

Results

In subjects with psychopathology, insomnia and short sleep duration were significantly associated with impaired work performance (odds ratio [OR] for insomnia, 2.20; [95% confidence interval {CI}, 1.50–3.22]; OR for short sleep, 2.54 [95% CI, 1.66–3.88] compared to normal sleep duration). Insomnia (OR, 2.48 [95% CI, 1.67–3.69]) and short sleep duration (OR, 1.85 [95% CI, 1.23–2.78]) also were associated with long-term absenteeism. These findings remained the same after considering clinical characteristics including medication use and symptom severity.In subjects without psychopathology, no significant associations were found between insomnia and short sleep duration on work functioning after considering subthreshold depression symptoms.

Conclusions

In subjects with psychopathology, sleep disturbances were negatively associated with work functioning, independent of disorder severity and use of psychotropic medication. Further research is needed to determine if treatment of sleep disturbances in subjects with psychopathology improves work functioning.     

The independent relationships between insomnia,depression, subtypes of anxiety,and chronotype during adolescence

ObjectivesTo investigate the independent effects of depression and subtypes of anxiety on insomnia, and vice versa, and the independent effect of chronotype on insomnia, depression, and subtypes of anxiety.MethodsIn all, 318 South Australian high school students from grades 7–11 (age range, 12–18 years; mean, 14.97 ± 1.34) participated in this cross-sectional study. Validated self-report questionnaires were used to assess insomnia, depression, subtypes of anxiety, and chronotype.ResultsAfter confounder variables were controlled, insomnia predicted depression and panic disorder (PD), whereas insomnia was predicted by depression and generalized anxiety disorder (GAD). Obsessive–compulsive disorder (OCD), separation anxiety (SAD), and social phobia (SP) were not significantly related to insomnia. Eveningness predicted the models in which depression and PD predicted insomnia and vice versa. Eveningness also predicted the models in which insomnia was predicted by OCD, SAD, and SP.ConclusionsInsomnia independently predicts depression and is predicted by depression and GAD, but not by other forms of anxiety. The independent prediction of insomnia on PD is unlikely to be clinically significant. Chronotype independently predicts and hence is a risk factor for insomnia and depression, but not subtypes of anxiety. Theoretical and clinical implications are discussed.

Insomnia symptoms increase during pregnancy,but no increase in sleepiness - Associations with symptoms of depression and anxiety

ObjectiveTo evaluate alteration in insomnia and sleepiness symptoms during pregnancy and assess early pregnancy risk factors for these symptoms, especially depressive and anxiety symptoms.MethodsA cohort of 1858 women was enrolled from the FinnBrain Birth Cohort Study. Insomnia and sleepiness symptoms were measured in early, mid- and late pregnancy with the Basic Nordic Sleep Questionnaire. Depressive symptoms were measured using the Edinburgh Postnatal Depression Scale and anxiety symptoms with the Symptom Checklist-90/Anxiety Scale. General linear models for repeated measures were conducted.ResultsGeneral sleep quality decreased (p < 0.001) and all insomnia types (p < 0.001) and sleep latencies (p < 0.001) increased as pregnancy proceeded. Snoring increased, but witnessed apneas remained rare. Nevertheless, morning (p = 0.019) and daytime (p < 0.001) sleepiness decreased from early to both mid-pregnancy and late pregnancy (p = 0.006 and p = 0.039). Women took more naps in early and late pregnancy compared to mid-pregnancy (both p < 0.001). Women with higher baseline anxiety symptoms had greater increase in sleep latency. At each pregnancy point, higher depressive and anxiety symptoms were associated with higher insomnia (p < 0.001) and sleepiness scores (p < 0.001) and higher depressive symptoms with longer sleep latencies (p < 0.001).ConclusionWe found a marked increase in insomnia symptoms throughout pregnancy. However, sleepiness symptoms did not increase correspondingly. Both depressive and anxiety symptoms in early pregnancy were associated with higher insomnia and sleepiness symptoms in later stages of pregnancy which emphasizes the importance of their assessment in early pregnancy.

Insomnia,anxiety, and depression during the COVID-19 pandemic: an international collaborative study

Importance and study objectiveThe COVID-19 pandemic has produced unprecedented changes in social, work, and leisure activities, which all have had major impact on sleep and psychological well-being. This study documented the prevalence of clinical cases of insomnia, anxiety, and depression and selected risk factors (COVID-19, confinement, financial burden, social isolation) during the first wave of the pandemic in 13 countries throughout the world.Design and participantsInternational, multi-center, harmonized survey of 22 330 adults (mean age = 41.9 years old, range 18–95; 65.6% women) from the general population in 13 countries and four continents. Participants were invited to complete a standardized web-based survey about sleep and psychological symptoms during the first wave of the COVID-19 pandemic from May to August 2020.ResultsClinical insomnia symptoms were reported by 36.7% (95% CI, 36.0–37.4) of respondents and 17.4% (95% CI, 16.9–17.9) met criteria for a probable insomnia disorder. There were 25.6% (95% CI, 25.0–26.2) with probable anxiety and 23.1% (95% CI, 22.5–23.6) with probable depression. Rates of insomnia symptoms (>40%) and insomnia disorder (>25%) were significantly higher in women, younger age groups, and in residents of Brazil, Canada, Norway, Poland, USA, and United Kingdom compared to residents from Asian countries (China and Japan, 8% for disorder and 22%–25% for symptoms) (all Ps < 0.01). Proportions of insomnia cases were significantly higher among participants who completed the survey earlier in the first wave of the pandemic relative to those who completed it later. Risks of insomnia were higher among participants who reported having had COVID-19, who reported greater financial burden, were in confinement for a period of four to five weeks, and living alone or with more than five people in same household. These associations remained significant after controlling for age, sex, and psychological symptoms.Conclusion and relevanceInsomnia, anxiety, and depression were very prevalent during the first wave of the COVID-19 pandemic. Public health prevention programs are needed to prevent chronicity and reduce long-term adverse outcomes associated with chronic insomnia and mental health problems.
