Job stress, social support, and prevalence of insomnia in a population of Japanese daytime workers

To clarify the relationship between perceived job stress, social support and prevalence of insomnia in Japanese daytime workers, 1161 male white-collar employees of an electric equipment manufacturing company (age, 23-60 years, mean age of 37.0) were surveyed by means of a mailed questionnaire. Perceived job stress was evaluated with the Japanese version of the generic NIOSH job stress questionnaire. Insomnia was diagnosed if workers had at least 1 of 3 types of symptoms on an almost nightly basis. The symptoms were (1) taking more than 30 min to fall asleep (Difficulty Initiating Sleep, DIS), (2) difficulty in maintaining sleep (DMS), or (3) early morning awakening (EMA). The overall prevalence of insomnia was 23.6% and the prevalences of the three subtypes were 11.3% for DIS, 14.2% for DMS, and 1.9% for EMA. Workers with high intragroup conflict (OR 1.6), high job dissatisfaction (OR 1.5), and high symptoms of depression (OR 2.0) (CES-D > 16) had a significantly increased risk for insomnia after adjusting for multiple confounding factors. Low employment opportunities, physical environment and low coworker support also were weakly associated with risk for insomnia among workers. Furthermore, high depressive symptoms significantly increased the risk of DIS (OR 2.4). Therefore in white-collar male daytime workers, psychological job stress factors such as interpersonal conflicts with fellow employees, job satisfaction, and social support were independently associated with a modestly increased risk of insomnia that included three different subtypes that were considered to be defining for the disorder.     

Cognitive Behavior Therapy for Chronic Insomnia in Occupational Health Services

Introduction The aim of this study was to examine the implementation and effectiveness of a cognitive behavioral group intervention model for chronic insomnia (CBT-I) in occupational health services (OHS). We also studied if insomnia symptoms and intervention effects differed on work days and days off. Methods The study design was a non-randomized group intervention, including a waiting period prior to CBT as a control condition. We followed up the results for a period of 6?months. Outcomes were assessed using a sleep diary, questionnaires, and actigraphy. The CBT-I groups were led by trained OHS nurses. Results A total of 26 participants completed the study. The intervention improved significantly participants?? different self-reported sleep variables, perceived severity of insomnia, sleep-related dysfunctional cognitions, and psychiatric and somatic symptoms. The effects lasted, and partly increased during the follow-up. The participants generally slept significantly better on days off than on work days, but the treatment improved sleep on both. Conclusions The study showed that a non-pharmacological treatment of insomnia can be implemented into OHS with a reasonable amount of effort and that the treatment delivered by trained OHS nurses yields promising results. These findings, however, need to be interpreted cautiously, due to the non-randomized design and small sample size.     

Estimated Prevalence of Insomnia among Women Veterans: Results of a Postal Survey

ObjectivesInsomnia is a significant public health concern known to particularly impact women and the veteran population; however, rates of insomnia disorder among women veterans are not known.MethodWomen veterans who had received health care at VA Greater Los Angeles Healthcare System between 2008 and 2010 and resided within 25 miles of the facility were sent a postal survey assessing sleep, demographics, and other related patient characteristics.ResultsA total of 660 women (43.1% of potential responders) returned the postal survey and provided sufficient information for insomnia diagnosis. On average, women reported 6.2 hours of sleep per night. The prevalence of insomnia, determined according to diagnostic criteria from the International Classification of Sleep Disorders-2, was 52.3%. Women with insomnia reported more severely disturbed sleep, and more pain, menopausal symptoms, stress/worries, and nightmares compared with women without insomnia. There was a quadratic relationship between age and insomnia with women in their mid-40s, most likely to have insomnia.ConclusionsThis survey study found that insomnia symptoms were endorsed by more than one-half of the women veterans in this sample of VA users, highlighting the critical need for enhanced clinical identification and intervention. Further research is needed to establish national rates of insomnia among women veterans and to improve access to evidence-based treatment of insomnia disorder.     

Prevalence and consequences of insomnia in New Zealand: disparities between Maori and non-Maori

OBJECTIVE: To investigate the prevalence of self-reported insomnia symptoms among Maori (Indigenous people) and non-Maori adults in the general population of New Zealand. To explore the consequences for health and quality of life experienced by those who report common insomnia complaints and sleeping problems. METHODS: In 2001, a two-page questionnaire was mailed to a stratified random sample of 4,000 adults aged 20-59 years nationwide. Participants were selected from the New Zealand electoral roll. The sample design aimed for equal numbers of Maori and non-Maori participants, men and women, and participants in each decade of age (72.5% response rate). RESULTS: Population prevalence estimates indicate that self-reported insomnia symptoms and sleeping problems are higher among Maori than non-Maori. Multiple logistic regression analyses showed that self-reported insomnia symptoms and/or sleeping problems are significantly associated with reporting poor or fair health and quality of life outcomes. CONCLUSIONS: Approximately one-quarter of adults in New Zealand may suffer from a chronic sleep problem, highlighting insomnia as a major public health issue in New Zealand. IMPLICATIONS: Significant differences in the prevalence of insomnia symptoms and current sleeping problems with respect to ethnicity have implications in the purchase and development of treatment services, with greater need for these services among Maori than non-Maori.     

Cognitive-Behavioral Group Therapy as an Early Intervention for Insomnia: A Randomized Controlled Trial

A randomized controlled design was used with a 1-yr follow-up. The purpose was to compare the effects of two early interventions, a cognitive-behavioral group intervention and a self-help information package, in patients with insomnia. In sum, 165 individuals seeking care for insomnia of 3–12 months duration were randomized to either a group receiving a CBT intervention or a group receiving a self-help information package. At the 1-yr follow-up, 136 participants had completed the entire study. At the 1-yr follow-up, the CBT group intervention was, compared with the control group, effective in producing reductions in dysfunctional beliefs and attitudes about sleep, negative daytime symptoms, as well as vital improvements in sleep (i.e. sleep onset latency, time awake after sleep onset, total sleep time, sleep quality, and sleep efficiency). In comparison with the control group, significantly more participants in the CBT group met criteria at the 1-yr follow-up for clinically meaningful improvements in sleep onset latency, time awake after sleep onset, and sleep efficiency. A CBT group intervention may well be a viable early intervention for patients with insomnia in a wide range of health services.     

Promoting social capital to alleviate loneliness and improve health among older people in Spain

Loneliness is especially frequent among older people in Southern Europe. Furthermore, promoting social capital to tackle loneliness and its health effects is an understudied intervention strategy. Therefore, a complex intervention was piloted in Spain in a pre–post study with a 2‐year follow‐up. Its aims were to explore the feasibility of the intervention and its short‐ and long‐term effects. It was conducted in one mixed rural–urban and two urban areas of diverse socioeconomic levels from 2011 to 2012. The intervention framework was based on social capital theory applying a behaviour change model and care co‐ordination. The intervention comprised: (i) a co‐ordinated action aimed at building a network between primary healthcare centres and community assets in the neighbourhood and (ii) a group‐based programme, which promoted social capital among lonely older people, especially social support and participation. Older people active in senior centres volunteered as gatekeepers. The main outcome domain was loneliness. Secondary outcome domains were participation, social support, self‐perceived health, quality of life, depressive symptoms and use of health resources. Pre–post changes were assessed with t‐test, Wilcoxon signed‐rank test and McNemar's test. Differences between the three time points were assessed with a one‐way ANOVA with repeated measures. Social workers and nurses were successfully involved as group leaders, 10 volunteers took part and 38 participants were included. After the intervention, loneliness decreased while social participation and support significantly increased. Furthermore, the number of visits to nurses increased. Exactly 65.8% of the participants built social contacts within the group and 47.4% became engaged in new activities. Two years later, social effects were maintained and depressive symptoms had decreased. Exactly 44.7% of the participants continued to be in contact with at least one person from the group and 39.5% continued participating. The intervention contributes a novel and feasible social capital‐based approach for alleviating loneliness among older adults while prompting meaningful changes in their lives.

目的 描述中国慢性病前瞻性研究（CKB）项目人群的睡眠时长、午睡习惯与失眠症状的人群分布,并分析睡眠因素之间的关联。方法 采用自行设计的电子问卷进行面对面基线调查,收集调查对象人口社会学特征、生活方式等信息。剔除患有冠心病、脑卒中、COPD或恶性肿瘤的个体后,共有452 829名30～79岁的研究对象纳入分析。描述不同人群调整性别、年龄、地区后的睡眠因素的分布特征;并分性别使用logistic回归分析睡眠因素间的关联。结果 研究对象平均每天睡眠时长为7.41 h;20.3%的研究对象一年四季均有午睡习惯,40.1%仅在夏季午睡,39.6%没有午睡习惯;研究对象自报“入睡困难”、“早醒”、“日间功能障碍”频率分别为11.0%、10.0%和2.1%。不同性别、年龄、地区、受教育程度、家庭年收入和婚姻状况人群的睡眠因素分布差异有统计学意义（P< 0.05）。随着睡眠时长的增加,失眠症状风险整体呈下降趋势（线性趋势检验P< 0.001）;没有午睡习惯者其入睡困难、早醒的风险更高（P< 0.05）;睡眠时间越长的人群中,有午睡习惯者所占比例越大（P< 0.05）。结论 不同社会人口学特征人群的睡眠时长、午睡习惯与失眠症状分布存在差异,睡眠因素之间也存在关联,故应在睡眠干预或临床诊疗中针对不同人群制定相应策略,并将睡眠因素综合考虑。     

Insomnia and its correlates in a representative sample of the Greek population

Background  

Insomnia is a major public health concern affecting about 10% of the general population in its chronic form. Furthermore, epidemiological surveys demonstrate that poor sleep and sleep dissatisfaction are even more frequent problems (10-48%) in the community. This is the first report on the prevalence of insomnia in Greece, a southeastern European country which differs in several socio-cultural and climatic aspects from the rest of European Community members. Data obtained from a national household survey (n = 1005) were used to assess the relationship between insomnia symptoms and a variety of sociodemographic variables, life habits, and health-related factors.     

Häufigkeit und Verteilung von Schlafproblemen und Insomnie in der deutschen Erwachsenenbevölkerung

Sleep disturbances are associated with a variety of physical and mental health disorders and cause high direct and indirect economic costs. The aim of this study was to report the frequency and distribution of problems of sleep onset and maintaining sleep, sleep quality, effective sleep time, and the consumption of sleeping pills in the adult population in Germany. During the 4 weeks prior to the interview, about one third of the respondents reported potentially clinically relevant problems initiating or maintaining sleep; about one-fifth reported poor quality of sleep. When additionally considering impairments during the daytime such as daytime fatigue or exhaustion, a prevalence of 5.7?% for an insomnia syndrome was found. Women were twice as likely to be affected by insomnia-syndrome as men. Significant age differences were not seen. Persons with low socioeconomic status had an increased risk of insomnia (OR: 3.44) as did people residing in West Germany (OR: 1.53). Women with low socioeconomic status (OR: 4.12) and West German men (OR: 1.79) were more affected. The results illustrate the considerable public health relevance of insomnia-related sleep disturbances.

Sleep disorder symptoms among nurses and nursing aides

Summary Nurses and nursing aides (n = 418) currently working on a regular evening or day schedule were compared in terms of sleep disorder symptoms. The relationship between past nightwork and sleep disorder symptoms was also assessed. The prevalence of individual symptoms varied from 6 to 53%. Evening workers showed a pattern of sleep disorder compatible with sleep deprivation, whereas the pattern for day workers was more compatible with insomnia. Past nightwork was significantly associated with symptoms of day tiredness and the quantity of sleep obtained was influenced by past nightwork. The prevalence of a combination of four insomnia symptoms (initial, intermittent, and terminal insomnia and fatigue during the day) was 5.4% among current day workers but no cases were identified among evening workers. Among day workers, the trend for insomnia across levels of duration of past nightwork fell slightly short of conventional statistical significance (P = 0.09). The relationship between a combination of four symptoms was neither modified nor confounded by variables such as age, chronotype, intensity of past nightwork, and latency. In conclusion, although some sleep symptoms were associated with nightwork, a clear residual effect on a combination of symptoms could not be shown.This project was supported by a grant from L'Institut de Recherche en Sante et Securite du Travail du Quebec     

Seasonal variations in sleep problems at latitude 63°-65° in Norway: The Nord-Trondelag Health Study, 1995-1997

Most studies on seasonal variability in sleep have asked participants if they think their sleep quality varies with the seasons, which reveals the research hypothesis to the participants. To date, the hypothesis of seasonal variation in sleep has not been tested in a large population-based fully blinded study. The aim of the current study was to investigate monthly variations in sleep problems in a geographic region of Norway with large seasonal differences in daytime light. Using data from a general health survey, the authors had access to information on sleep in the general population, collected across the seasons over 2 years without linking sleep to seasonal variation. In all, 43,045 participants (mean age, 44.6 years) of the Nord-Tr?ndelag Health Study, 1995-1997 (referred to as "HUNT-2"), provided reports of insomnia symptoms and time in bed in all months except July. The mean prevalence of insomnia symptoms was 12.4%. No evidence of a seasonal variation on reports of insomnia symptoms or time in bed was found. These null findings are in marked contrast to previous seasonality studies of sleep. Previous studies reporting seasonal variations in sleep and insomnia might have been subject to publication biases and lack of blinding to the research hypothesis.     

Associations between sleep disturbance and alcohol drinking: A large-scale epidemiological study of adolescents in Japan

In this study, we attempted to clarify the associations between various sleep disturbance symptoms and the frequency and amount of alcohol use among Japanese adolescents. This study was designed as a cross-sectional sampling survey. A self-administered questionnaire survey was administered to students enrolled in randomly selected junior and senior high schools throughout Japan. A total of 99,416 adolescents responded, and 98,867 questionnaires were subjected to analysis. The prevalence rates of sleep disturbance in the 30 days preceding the day of the survey were as follows: subjectively insufficient sleep (SIS) (boys: 37.6%, girls: 38.7%); short sleep duration (SSD) with less than 6 h of sleep (boys: 28.0%, girls: 33.0%); difficulty initiating sleep (DIS) (boys: 12.5%, girls: 14.1%); difficulty maintaining sleep (DMS) (boys: 10.1%, girls: 10.9%); and early morning awakening (EMA) (boys: 5.1%, girls: 5.0%). Adolescents reporting one or more symptoms of DIS, DMS, and EMA were classified as having insomnia, and its prevalence was 21.5%. The prevalence of each symptom of sleep disturbance increased significantly with the number of days on which alcohol was consumed in the previous 30 days and the amount of alcohol consumed per drinking session (p < 0.01). Multiple logistic regression analyses showed that the adjusted odds ratio (AOR) for each symptom of sleep disturbance, except SIS and EMA, tended to increase with the number of days on which alcohol was consumed and the amount of alcohol consumed per drinking session. The prevalence of sleep disturbance is particularly high among adolescents drinking alcohol. The risk of having each symptom of sleep disturbance, except SIS and EMA, increases with the number of days on which alcohol was consumed and the amount of alcohol consumed per drinking session. These findings reconfirm the need to eliminate underage drinking to ensure good sleep among adolescents.     

Help-seeking for insomnia among adult patients in primary care

OBJECTIVE: To clarify the patient characteristics associated with seeking medical help for insomnia. METHODS: A consecutive sample (n = 700) of adults attending a non-urgent primary care appointment was screened for sleep problems. A follow-up mailed survey then assessed insomnia symptoms, daytime impairment, beliefs about sleep, medication use, sleepiness and fatigue, and medical help-seeking. RESULTS: Fifty-two percent of patients with probable insomnia reported discussing this with a physician. Multivariate logistic regression analyses indicated that discussing one's probable insomnia with a physician was independently associated with having a greater number of medical conditions (OR, 2.19 [95% CI, 1.13 to 4.22]), being more highly educated (1.67 [95% CI, 1.11 to 2.51]), sleeping less per night (OR, 0.71 [95% CI, 0.52 to 0.96]), and greater perceived daytime impairment due to insomnia (OR, 2.07 [95% CI, 1.06 to 4.03]). CONCLUSIONS: Primary care patients often seek medical help when they experience insomnia. Clinical treatment ought to especially target poor sleepers presenting with significant insomnia-related impairment, medical morbidity, or both. Future research should further clarify the role of medical and psychiatric comorbidities and determine whether resolution of insomnia and its consequences improves the outcomes of common medical conditions.     

Risk factors for insomnia in a rural population

PURPOSE: This study compared in one data set the relative importance of most previously examined risk factors for different symptoms of insomnia. METHODS: Data were obtained from personal interviews of 1,588 adults in a rural area. Statistical methods evaluated the association of 42 risk factors with any insomnia and each of four insomnia subtypes: difficulty with initiating sleep (DIS), difficulty maintaining sleep (DMS), early morning awakening (EMA), and restless sleep (RS). RESULTS: Insomnia rates were greater in this rural population than most U.S. studies and greater in the United States than other countries. The correlations between insomnia subtype and energy level was highest for RS, -0.29, and lowest for EMA, -0.11. All sleep disturbances increased monotonically with depressive symptoms, but the increase was greatest for RS (r = 0.57) and weakest for EMA (r = 0.24). Anxiety and pain also were independently associated with each insomnia subtype. Insomnia problems of spouses were uncorrelated. Other risk factors were independently associated with some insomnia subtypes but not others. For example, the association of age with difficulty maintaining sleep was independent of health measures. CONCLUSION: The results suggest that different insomnias have different rates and risk factors and therefore possibly different etiologies and management strategies.     

Factors affecting COVID-19 vaccine hesitancy among healthcare providers in 23 countries

BackgroundSeveral early COVID-19 studies aimed to assess the potential acceptance of a vaccine among healthcare providers, but relatively few studies of this population have been published since the vaccines became widely available. Vaccine safety, speed of development, and low perceived disease risk were commonly cited as factors for COVID-19 vaccine hesitancy among this group.Purpose and methodsIn a secondary analysis based on a cross-sectional, structured survey, the authors aimed to assess the associations between self-reported vaccine hesitancy and a number of sociodemographic and COVID-19 vaccine perception factors using data from 3,295 healthcare providers (physicians, nurses, community health workers, other healthcare providers) in 23 countries.Findings494 (15.0%) of the participants reported vaccine hesitancy, of whom 132 (4.0%) would outright refuse to accept a COVID-19 vaccine. Physicians were the least hesitant. Vaccine hesitancy was more likely to occur among those with less than the median income and, to a lesser degree, younger age. Safety and risk concerns and lack of trust that vaccines would be equitably distributed were strongly associated with hesitancy, less so were concerns about the efficacy of COVID-19 vaccines.InterpretationFindings suggest a need to address safety and risk concerns through tailored messaging, training, and/or incentive approaches among healthcare providers, as well as the need for international and national vaccination efforts to ensure equitable distribution.     

Sociodemographic and socioeconomic differences in sleep duration and insomnia-related symptoms in Finnish adults

ABSTRACT: BACKGROUND: Poor sleep tends to be patterned by sociodemographic and socioeconomic factors. The aim of this study was to examine the associations of sociodemographic and socioeconomic factors with sleep duration and insomnia-related symptoms across life course. METHODS: We used cross-sectional Health 2000 Survey (2000-2001) among a total of 5,578 adult Finns, aged 30-79 years, representative of adult Finnish population. Data about sociodemographic and socioeconomic circumstances, insomnia-related symptoms over the previous month as well as average sleep duration were collected by questionnaires. Multinomial logistic regression models were adjusted first for gender and age, second for sociodemographic factors, and third for all covariates simultaneously. RESULTS: On average 70% of Finnish adults slept 7-8 hours a day. Frequent insomnia-related symptoms were more prevalent among women (14%) than men (10%). Not being married, not having children, having low education, low income, being unemployed, and being a disability retiree were associated with frequent insomnia-related symptoms. Similar factors were associated with short and long sleep duration. However, childhood socioeconomic position was mostly unrelated to sleep in adulthood except parental education had some associations with short sleep duration. CONCLUSIONS: Disadvantaged socioeconomic position in adulthood, in particular income and employment status, is associated with poorer sleep. When promoting optimal sleep duration and better sleep quality, families with low incomes, unemployed people, and disability retirees should be targeted. Key words: marital status; parental status; education; employment status; household income; residential area; insomnia-related symptoms; sleep duration; life course; self-perceived health.

The intersecting cognitive and aging needs of HIV-positive older adults: Implications for social work practice

Cognitive impairment is a significant health concern for people aging with HIV/AIDS. Using a community-based participatory research (CBPR) framework, we surveyed (n = 108) and interviewed (n = 20) people living with HIV who were over age 50 about their cognitive concerns and recommendations for social work intervention development. Quantitative findings indicate that our sample was greatly engaged in their HIV care, yet participants had many cognitive concerns. Qualitative findings highlighted fear, shame, and uncertainty concerning HIV and aging alongside a need for increased social work support. This paper provides practical engagement strategies for social workers to support clients concerning HIV, aging, and cognition.     

Voices of South Asian women: immigration and mental health

PURPOSE: This qualitative research aimed to elicit experiences and beliefs of recent South Asian immigrant women about their major health concerns after immigration. METHODS: Four focus groups were conducted with 24 Hindi-speaking women who had lived less than five years in Canada. The audiotaped data were transcribed, translated, and analyzed by identification of themes and subcategories. RESULTS: Mental health (MH) emerged as an overarching health concern with three major themes i.e. appraisal of the mental burden (extent and general susceptibility), stress-inducing factors, and coping strategies. Many participants agreed that MH did not become a concern to them until after immigration. Women discussed their compromised MH using verbal and symptomatic expressions. The stress-inducing factors identified by participants included loss of social support, economic uncertainties, downward social mobility, mechanistic lifestyle, barriers in accessing health services, and climatic and food changes. Women's major coping strategies included increased efforts to socialize, use of preventative health practices and self-awareness. CONCLUSION: Although participant women discussed a number of ways to deal with post-immigration stressors, the women's perceived compromised mental health reflects the inadequacy of their coping strategies and the available resources. Despite access to healthcare providers, women failed to identify healthcare encounters as opportunities to seek help and discuss their mental health concerns. Health and social care programs need to actively address the compromised mental health perceived by the studied group.     

Sleep disturbance in cancer patients

Sleep difficulty is a prominent concern of cancer patients, yet there has been no large study of the prevalence and nature of sleep disturbance in cancer patients. This cross-sectional survey study examined: (a) the prevalence of reported sleep problems in patients attending six clinics at a regional cancer centre; (b) sleep problem prevalence in relation to cancer treatment; and (c) the nature of reported insomnia (type, duration, and associated factors). For three months, all patients attending clinics for breast, gastrointestinal, genitourinary, gynecologic, lung, and non-melanoma skin cancers were offered a brief sleep questionnaire. Response rate was 87%; the final sample size was 982. Mean age of respondents was 64.9 years (SD 12.5). The most prevalent problems were excessive fatigue (44% of patients), leg restlessness (41%). insomnia (31%), and excessive sleepiness (28%). Chi square tests showed significant variation among clinics in the prevalence of most sleep problems. The lung clinic had the highest or second-highest prevalence of problems. The breast clinic had a high prevalence of insomnia and fatigue. Recent cancer treatment was associated with excessive fatigue and hypersomnolence. Insomnia commonly involved multiple awakenings (76% of cases) and duration > or = 6 months (75% of cases). In 48% of cases, insomnia onset was reported to occur around the time of cancer diagnosis (falling within the period 6 months pre-diagnosis to 18 months post-diagnosis). The most frequently identified contributors to insomnia were thoughts, concerns, and pain/discomfort. In a multivariate logistic regression analysis, variables associated with increased odds of insomnia were fatigue, age (inverse relationship), leg restlessness, sedative/hypnotic use, low or variable mood, dreams, concerns, and recent cancer surgery. This study provides new information about sleep-related phenomena in cancer patients, information which will be useful in planning supportive care services for cancer patients.
