Abstract
Insomnia is a common symptom that may interfere with the efforts of alcohol-dependent patients to initiate and maintain sobriety. This study investigates the experiences of recovering alcohol-dependent patients with insomnia as well as preferences for treatment strategies. Semi-structured interviews were conducted with 27 patients in Ukraine and Germany. Most of the patients experienced negative psychological (n = 21), physiological (n = 14) effects and negative daytime consequences during insomnia. All 27 patients were engaged in nonpharmacological approaches to insomnia and 52% used pharmacological approaches to manage insomnia. This study provides insight for understanding how alcohol-dependent patients in recovery perceive insomnia.

Relationship between insomnia with alcohol drinking before sleep (Ne-Zake) or in the morning (Mukae-Zake) among Japanese farmers. Alcohol 2021; 93:57-62. [PMID: 33745986 DOI: 10.1016/j.alcohol.2020.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 11/10/2020] [Accepted: 11/27/2020] [Indexed: 10/21/2022]
Abstract
BACKGROUND Ne-Zake is the drinking of alcohol before sleeping for helping to fall asleep and sleep well, and Mukae-Zake is the drinking of alcohol in the morning for "calming down" or "curing hangovers". OBJECTIVE We sought to examine the relationship of insomnia with Ne-Zake and Mukae-Zake among healthy middle-aged Japanese farmers. METHODS In a cross-sectional study of 746 participants (mean age, 59.5 years; women, 25.9%), Ne-Zake and Mukae-Zake were defined based on a self-administered questionnaire. Insomnia was defined as the Athens Insomnia Scale Japanese version ≥6 or usage of sleeping pills in the previous year. Logistic regression was used to calculate odds ratio (OR) of insomnia related to Ne-Zake and Mukae-Zake adjusting for sex, age, presence of sleep-related disorders, frequency of alcohol consumption, and quantity of alcohol consumed per one occasion. RESULTS We observed insomnia, Ne-Zake, and Mukae-Zake in 174 (23.3%), 140 (18.8%), and 37 (5.0%) participants, respectively. After adjustment for demographic and confounding factors, participants with Ne-Zake had a significantly higher prevalence of insomnia (OR 2.00 [95% confidence interval, 1.27-3.16]), compared to those without Ne-Zake. Mukae-Zake was also independently associated with a higher prevalence of insomnia among men (OR 3.26 [1.55-6.87]). Participants with both Ne-Zake and Mukae-Zake had a highly significant association with insomnia (OR 4.77 [2.01-11.3]) than those with neither Ne-Zake nor Mukae-Zake. Additionally, for insomnia, the association of Mukae-Zake was more pronounced than that of Ne-Zake (OR 4.09, 95% CI 1.14-14.7, p = 0.031; and OR 1.81, 95% CI 1.08-3.06, p = 0.026, respectively). CONCLUSION Ne-Zake and Mukae-Zake were associated with insomnia independent of the quantity and frequency of alcohol consumption among Japanese farmers. This finding can be used for stratifying individuals with insomnia not only to improve sleep hygiene but also to prevent alcohol dependence by informing the general population that alcohol has a negative effect on sleep, contrary to popular beliefs.

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
Insomnia and depressive symptoms are common symptoms among alcohol-dependent (AD) patients. AD individuals (N = 364) were assessed during 2004-2009 in the Midwestern United States at baseline and 6-month intervals with the Sleep Problems Questionnaire, Time-Line Follow-Back interview, and the depression subscale of the Brief Symptom Inventory. Hierarchical Linear Modeling was used to analyze the data in this longitudinal study. When modeled separately, both quantity of drinking (p < .01) and depression (p < .001) predicted insomnia severity, controlling for time, age, and gender. Drinking also predicted depressive symptoms (p < .001), and its effect on insomnia was mediated by depression severity (p < .001).

Abstract
BACKGROUND Insomnia is an important symptom in alcohol-dependent patients because it may persist despite abstinence and predispose to relapse to drinking. The goal of the present study was to evaluate the prevalence and clinical correlates of insomnia in a sample of 302 alcohol-dependent patients admitted to treatment programs in Poland. METHODS Participants were mostly men (73.8%) with a mean (SD) age of 43.5 (9.7) years. Insomnia in the past 1 month was assessed using a total score of 6 or higher on the Athens Insomnia Scale. RESULTS Insomnia affected 62.9% of patients, and delayed sleep induction was the most common subtype. Insomnia was associated in bivariate analyses with less education, inadequate finances, problem drinking at an earlier age of onset, drinking frequency and quantity, drinking-related consequences, severity of alcohol and nicotine dependence, psychiatric and physical severity, and a childhood history of sexual or physical abuse (p < 0.05). Logistic regression analysis showed that mental and physical health status, severity of alcohol dependence, number of drinking days in the past 3 months, and childhood abuse were independent predictors of insomnia, explaining approximately 30 to 40% of the variance. CONCLUSIONS More than 60% of alcohol-dependent patients in a Polish sample screened positive for insomnia using a validated scale, a rate similar to those assessed with other scales in other countries. The study also showed that insomnia in alcohol-dependent patients is associated with poor physical health and childhood abuse, similar to the general population. The multifactorial nature of insomnia in alcohol-dependent patients has treatment implications.

Abstract
STUDY OBJECTIVES Insomnia is common, persistent, and associated with relapse in alcohol-dependent (AD) patients. Although the underlying mechanisms are mostly unstudied, AD patients have impaired circadian rhythms and sleep drive, which may be genetically influenced. A polymorphism in the PER3 gene (PER3(4/4), PER3(4/5), PER3(5/5)) has previously been associated with circadian preference and sleep homeostasis, and the PER3(4/4)genotype has been characterized by evening preference and decreased sleep drive. The purpose of this study was to examine the influence of this polymorphism on insomnia severity in AD patients. We hypothesized that the PER3 polymorphism would be an independent predictor of insomnia severity with greatest severity observed in those with the PER3(4/4)genotype. DESIGN Cross-sectional association of patient characteristics, genotype, and insomnia severity. Significant (P < 0.05) bivariate correlates were further analyzed by hierarchical, forced entry multiple linear regression. SETTING Alcohol treatment programs in Warsaw, Poland. PATIENTS Diagnosed with alcohol dependence (n = 285), according to the Diagnostic and Statistical Manual of Mental Disorders, 4(th) edition. MEASUREMENTS AND RESULTS Drinking frequency, mental and physical health status, childhood abuse, and PER3 genotype were independent predictors of insomnia severity, as measured by a 7-item subscale of the Sleep Disorders Questionnaire, explaining 28.9% of the variance. Addition of the genotype in the final step significantly increased the amount of variance explained by 1.1% (P = 0.027). Those with the PER3(4/4)genotype had the greatest severity of insomnia symptoms. CONCLUSIONS PER3 genotype contributed unique variance in predicting insomnia severity in AD patients. These results are consistent with genetically influenced impairment in sleep regulation mechanisms in AD patients with insomnia.

Abstract
Insomnia is common, persistent, and increases the risk for relapse in alcohol-dependent (AD) patients. Abstinence has long been considered the best strategy for allowing sleep to normalize, although how many and which patients respond to abstinence is unknown. The aims of this study were to investigate the prevalence and correlates of both baseline and persistent insomnia in AD patients. The course of sleep problems in response to abstinence, moderate drinking, or relapse following treatment was also examined. A naturalistic longitudinal outcomes study interviewed 267 patients (69% male; mean age of 44 years) with DSM-IV alcohol dependence at baseline and 6 months later (84% follow-up rate) . The Sleep Problems Questionnaire, Time-Line Follow-Back Interview, and Brief Symptom Inventory measured insomnia, drinking, and psychiatric symptoms, respectively. Simple correlations, logistic regression, and repeated measures analysis of variance were used to analyze the data. At baseline, 47% of patients were classified with insomnia, which was independently predicted by female gender and psychiatric severity. Both abstinence and moderate drinking outcomes significantly predicted a reduction of insomnia symptoms after controlling for gender and psychiatric severity. Among patients with baseline insomnia, however, insomnia persisted in over 60% of cases, which was predicted by baseline insomnia severity. Moreover, insomnia persisted in one-quarter of patients despite abstinence. Treatment aimed at preventing relapse to heavy drinking provides good first-line therapy for insomnia in AD patients, but some may require insomnia-specific evaluation and treatment in addition to substance-focused treatment and psychiatric care.

Abstract
We examined the individual association between body mass index (BMI) and sleep quality among the very elderly. The present study analyzed data from survey that was conducted on all residents aged 90 years or more in a district, there were 2,311,709 inhabitants in 2005. Subjects were divided into four groups according to quartile of BMI (<16.6, 16.6-18.9, 18.9-21.1, >21.1 kg/m(2)) and according to classification criteria of underweight, normal weight, overweight, and obesity in BMI (<18.5, 18.5-23.0, 23.0-27.5, >27.5 kg/m(2)), respectively. Sleep quality was measured using The Pittsburgh Sleep Quality Index (PSQI). Sleep quality included quality classification and scores, sleep duration, sleep latency, and sleep efficiency. The subjects included in the statistical analysis were 216 men and 444 women. According to quartile of BMI or classification criteria of underweight, normal weight, overweight, and obesity in BMI, none of the differences in sleep quality scores, sleep latency, sleep duration, sleep efficiency percentage, and prevalence of poor sleep quality was significant among different BMI groups. The difference in BMI between subjects with good and poor sleep quality was non-significant. Unadjusted and adjusted multiple logistic regression showed that none of the BMI groups had a function of decreasing the risk for poor quality. Among longevity Chinese, there is no association between BMI and sleep quality.

Abstract
Insomnia is often associated with substance dependence, with evidence suggesting that individuals seeking medical attention for sleep complaints are more likely to have drug or alcohol abuse problems than the general population. Disturbed sleep is associated with the abuse of a variety of drugs, with patients dependent on nicotine, alcohol and illicit drugs all reporting poor sleep. In addition, withdrawal from nicotine, alcohol and drugs of abuse is also associated with insomnia, and this may result in an increased risk of relapse if the sleep problems remain unresolved. Although studies suggest that the majority of pharmacological and behavioural interventions for insomnia are effective in treating sleep disturbances in dependent patients undergoing short-term drug withdrawal and short and long-term alcohol withdrawal, several questions remain unanswered. For example, little is known about the risk of relapse in abstinent drug-dependent patients experiencing withdrawal-related insomnia, the effect of insomnia treatment on nicotine withdrawal, or whether insomnia interventions prevent relapse. Participants of a workshop, held at the 6th annual meeting of The International Sleep Disorders Forum: The Art of Good Sleep in 2008, evaluated whether the effective management of sleep disorders could reduce substance dependence and the risk of relapse. Following the workshop a targeted literature review was conducted addressing this question. Data from this review that either pharmacological or cognitive behavioural treatment of insomnia could reduce the risk of relapse in substance dependence were substantially lacking. Further research is therefore required to increase our understanding of the impact of insomnia on patients with substance dependence.

Abstract
Virtually all psychiatric and substance use disorders are associated with sleep disruption. Studies indicate that psychiatric disorders are related closely to chronic insomnia and that psychoactive substances have acute and chronic effects on sleep architecture. Several aspects of sleep are compromised in individuals taking these substances, ranging from difficulty initiating sleep to difficulty maintaining sleep and hypersomnia. Sleep disturbances are apparent in person taking psychoactive drugs or alcohol and have been found to persist long after withdrawing from these drugs. For some, sleep disturbance can be so severe as to reverse treatment success and precipitate relapse to addiction or dependence. There is increasing evidence that primary insomnia without a concurrent psychiatric disorder is a risk factor for later developing substance use disorders. Patients were asked to complete two brief screening tools, the Michigan Alcohol Screening Test and Drug Abuse Screening Test, to examine substance use patterns among patients referred for a variety of sleep complaints in a sleep disorders clinic. We found that patients who demonstrated a variety of sleep complaints were more likely to have alcohol and drug problems than those in the general populations.

Abstract
BACKGROUND We examined the fluctuation and causes of voiding frequency during the night in patients with symptomatic nocturia. MATERIALS AND METHODS Actual night time frequency was recorded by 72 patients for a total of 769 nights (mean 10.7 nights per patient) and was compared with the 'nocturia score' of the International Prostate Symptom Scores (I-PSS). If a patient experienced nocturnal frequency higher or lower than usual, he or she checked the items on a questionnaire considered reasons for the changes. RESULTS For 471 nights of 769 (61%), actual voiding frequency did not correspond with nocturia score. Patient-by-patient fluctuation in actual voiding frequency during the night was marked. The most prevalent patient-reported reason for fluctuation was amount of fluid intake, followed by duration of time in bed, feeling colder or warmer during time in bed and increased difficulty going to sleep. Fatigue, difficulty going to sleep and salt intake could affect night time frequency positively or negatively. When nocturia score and total score of the I-PSS were high, the differences between actual nocturnal frequency and nocturia score were significantly larger (3 or less, 0.71; 3-4 or more, 1.05, P<0.0001 and 13 or less, 0.78; 14 or more, 0.97; P=0.0030, respectively). Female patients tended to have nocturia scores differing from actual frequency of urination (1.03 versus male patients 0.84, P=0.0673). CONCLUSIONS There is considerable discrepancy between the nocturia score of the I-PSS and actual voiding frequency, in addition to marked fluctuation of actual voiding frequency in symptomatic patients. Patient perception of fluctuation of night time frequency can provide clues to useful clinical education of patients regarding nocturia.

Abstract
Insomnia and alcoholism are significantly associated in community surveys and patient samples. Insomnia occurs in 36-72% of alcoholic patients and may last for weeks to months after initiating abstinence from alcohol. Some correlates of insomnia in alcoholic patients are identical to those observed in non-alcoholic insomniacs, including anxiety and depression, tobacco smoking, and the use of alcohol to aid sleep. Other studies suggest that as the severity of alcoholism increases, so does the likelihood of insomnia in alcoholic patients. In the sleep laboratory, alcoholic patients who complain of insomnia have disrupted sleep continuity when compared to alcoholic patients without insomnia complaints. Recently sober alcoholics are also more likely than non-alcoholics to have sleep-disordered breathing and increased periodic leg movements, which might contribute to insomnia in some alcoholic patients. The co-occurrence of insomnia and alcoholism is clinically significant because alcoholism can exacerbate the adverse consequences of insomnia (e.g. mood changes and performance decrements) and because insomnia among patients entering treatment for alcoholism has been significantly associated with subsequent alcoholic relapse. Baseline polysomnographic correlates of subsequent relapse include prolonged sleep latency, decreased sleep efficiency and total sleep time, increased rapid eye movement sleep pressure, and decreased slow wave sleep. Whether treatment of insomnia in alcoholic patients reduces relapse rates is unknown, but preliminary treatment guidelines that accommodate the special characteristics of alcoholic patients are provided, with a goal to reduce daytime impairment and psychological distress.

Abstract
Sixty DSM-IV alcohol dependent adults (39 males, 21 females) admitted to a voluntary sector alcohol detoxification unit in South London were studied. Socio-demographic data and information on level of alcohol dependence, quality of life, family history, cigarette smoking and the use of prescription/illicit drugs were collected. The subjects were followed-up at 12 weeks and subdivided into two groups, relapse and non-relapse. A relapse was defined as drinking 21 units or more per week for males and 14 units or more per week for females. Data were analysed for baseline and 12-week follow-up comparisons. At 12 weeks, 58 (97%) subjects (38 males, 20 females) were successfully followed-up and 36/58 (62%) had relapsed. After controlling for a Type I error there were significant differences between the relapse and non-relapse subgroups at 12-week followup on the following outcome measures; depression, life situation, withdrawal symptoms, energy, emotional reactions and social isolation. There were no significant differences at baseline between the relapse and nonrelapse subgroups for most of the socio-demographic variables, but Irish nationality and membership of lower social classes (IV and V) were associated with relapse. Major predictors of relapse at baseline after a forward stepwise logistic regression were (in order of increasing statistical significance) Irish nationality, lower social class, greater number of cigarettes smoked and disturbed sleep. The findings are discussed with reference to their consistency with existing research and potential clinical implications.

Abstract
To assess the effect of progressive relaxation training on insomnia in institutionalised chronic alcoholic men, 22 subjects between the ages of 20 and 60 years, were randomly allocated to treatment and control groups. The treatment group received 10 sessions of progressive relaxation training over a 2-wk. period after which both groups completed a postexperimental questionnaire. Analysis showed a significant improvement in the sleeping patterns of the treated group, but no changes in the sleeping patterns of the control group. In addition, a distribution-free two-sample permutation test to compare mean differences of the groups confirmed that a significantly greater change occurred in the quality of the sleeping patterns of the treated group.
