The association between burnout and physical illness in the general population--results from the Finnish Health 2000 Study

OBJECTIVE: The association between burnout and physical diseases has been studied very little. The purpose of this study was to examine the relationship between burnout and physical illness in a representative nationwide population health study. METHODS: As a part of the "Health 2000 Study" in Finland, 3368 employees aged 30-64 years were studied. Burnout was assessed with the Maslach Burnout Inventory-General Survey. Physical diseases were diagnosed in a comprehensive health examination by research physicians. RESULTS: Physical illness was more common among subjects with burnout than others (64% vs. 54%, P<.0001), and the prevalence of diseases increased with the severity of burnout (P<.0001). Burnout was an important correlate of cardiovascular diseases among men (OR=1.35; 95% CI, 1.13-1.61) and musculoskeletal disorders among women (OR=1.22, 95% CI, 1.07-1.38) when adjusted for age, marital status, education, socioeconomic status, physical strenuousness of work, smoking, physical activity, alcohol consumption, body mass index, and depressive symptoms. The prevalence of musculoskeletal disorders and cardiovascular diseases increased with the severity of all three dimensions of burnout, that is, exhaustion (P<.0001 and P<.001, respectively), cynicism (P=.0001 and P<.001, respectively), and lack of professional efficacy (P<.01 and P<.0001, respectively). CONCLUSIONS: Burnout is associated with musculoskeletal diseases among women and with cardiovascular diseases among men. These associations are not explained by sociodemographic factors, health behavior, or depression. Physical illnesses are associated with all three dimensions of burnout and not only with the exhaustion dimension. In the future, the causal relationships between burnout and physical diseases need to be investigated in prospective studies.     

Burnout as a predictor of all-cause mortality among industrial employees: A 10-year prospective register-linkage study

Objective

Burnout, a psychological consequence of prolonged work stress, has been shown to coexist with physical and mental disorders. The aim of this study was to investigate whether burnout is related to all-cause mortality among employees.

Methods

In 1996, of 15,466 Finnish forest industry employees, 9705 participated in the ‘Still Working’ study and 8371 were subsequently identified from the National Population Register. Those who had been treated in a hospital for the most common causes of death prior to the assessment of burnout were excluded on the basis of the Hospital Discharge Register, resulting in a final study population of 7396 people. Burnout was measured using the Maslach Burnout Inventory-General Survey. Dates of death from 1996 to 2006 were extracted from the National Mortality Register. Mortality was predicted with Cox hazard regression models, controlling for baseline sociodemographic factors and register-based health status according to entitled medical reimbursement and prescribed medication for mental health problems, cardiac risk factors, and pain problems.

Results

During the 10-year 10-month follow-up, a total of 199 employees had died. The risk of mortality per one-unit increase in burnout was 35% higher (95% CI 1.07-1.71) for total score and 26% higher (0.99-1.60) for exhaustion, 29% higher for cynicism (1.03-1.62), and 22% higher for diminished professional efficacy (0.96-1.55) in participants who had been under 45 at baseline. After adjustments, only the associations regarding burnout and exhaustion were statistically significant. Burnout was not related to mortality among the older employees.

Conclusion

Burnout, especially work-related exhaustion, may be a risk for overall survival.     

Mental disorders and employee sickness absence: the NEMESIS study

  Background: This study aimed to determine to what extent different forms of mental disorders are related to an increased likelihood of sickness absence and whether this increase depends on the employee's sex. Methods: Data of 3695 employed persons aged 18–64 years from a national sample of the Dutch population were derived from the first two waves of the Netherlands Mental Health Survey and Incidence Study (NEMESIS). Mental disorders (DSM-III-R) in the past 12 months were assessed at baseline (1996). Subsequent sickness absence was assessed at the follow-up 1 year later. Somatic illnesses and age were included as controlled confounders. Results: Major depressive disorder, dysthymia, simple phobia and drug abuse/dependence were predictive of sickness absence in men. In women, the associations were weaker, and none of the 1-year DSM-III-R disorders was significantly related to the likelihood of sickness absence. Conclusions: Mental disorders are a more important risk factor for sickness absence for male employees than for female employees. Knowledge of this sex difference can be valuable for the development of interventions aiming at reducing sickness absence rates due to mental illness. Accepted: 2 November 1999     

The mental health effects of multiple work and family demands

Background Individuals who experience work stress or heavy family demands are at elevated risk of poor mental health. Yet, the cumulative effects of multiple work and family demands are not well known, particularly in men. Methods We studied the association between multiple work and family demands and sickness absence due to non-psychotic psychiatric disorders in a longitudinal study conducted among members of the French GAZEL cohort study (8,869 men, 2,671 women) over a period of 9 years (1995–2003). Work stress and family demands were measured by questionnaire. Medically certified psychiatric sickness absence data were obtained directly from the employer. Rate ratios (RRs) of sickness absence were calculated using Poisson regression models, adjusting for age, marital status, social support, stressful life events, alcohol consumption, body mass and depressive symptoms at baseline. Results Participants simultaneously exposed to high levels of work and family demands (≥2 work stress factors and ≥4 dependents) had significantly higher rates of sickness absence due to non-psychotic psychiatric disorders than participants with lower levels of demands (compared to participants exposed to 0–1 work stress factors and with 1–3 dependents, age-adjusted rate ratios were 2.37 (95% CI 1.02–5.52) in men and 6.36 (95% CI 3.38–11.94) in women. After adjusting for baseline socio-demographic, behavioral and health characteristics, these RRs were respectively reduced to 1.82 (95% CI 0.86–3.87) in men, 5.04 (95% CI 2.84–8.90) in women. The effect of multiple work and family demands was strongest for sickness absence due to depression: age-adjusted RRs among participants with the highest level of work and family demands were 4.70 (1.96–11.24) in men, 8.57 (4.26–17.22) in women; fully adjusted RRs: 3.55 (95% CI 1.62–7.77) in men, 6.58 (95%CI 3.46–12.50) in women. Conclusions Men and women simultaneously exposed to high levels of work stress and family demands are at high risk of experiencing mental health problems, particularly depression.     

Depressive symptoms and the risk of long-term sickness absence

Background The aim of this paper is to examine the impact of depressive symptoms on long-term sickness absence in a representative sample of the Danish workforce. Methods This prospective study is based on 4,747 male and female employees, participating in the Danish Work Environment Cohort Study. Depressive symptoms were measured at baseline. Data on sickness absence were obtained from a national register on social transfer payments. Onset of long-term sickness absence was followed up for 78 weeks. Results The cumulative 78 weeks incidence for the onset of long-term sickness absence was 6.5% in men and 8.9% in women. Both men and women with severe depressive symptoms (≤52 points) were at increased risk of long-term sickness absence during follow-up (men: HR = 2.69; 95% CI: 1.18, 6.12; women: HR = 2.27; 95% CI: 1.25, 4.11), after adjustment for demographic, health related, and lifestyle factors. When we divided the depressive symptom scores into quartiles, we found no significant effects with regard to long-term sickness absence. Conclusions Severe depressive symptoms, as measured with the MHI-5, increased the risk of future long-term sickness absence in the general Danish working population. However, effects were not linear, but occurred mostly only in those employees with high levels of depressive symptoms.     

Sickness absence and disability pension in a cohort of employees initially on long-term sick leave due to psychiatric disorders in Sweden

Background Over the last decade sickness absence and disability pension (DP) due to psychiatric disorders have increased considerably in Western countries. The scientific knowledge base about prognoses for such absences is very limited, but employers and clinicians often predict them to be very long. The aim of this study was to investigate sickness absence and disability pension in a cohort of employees who initially were on long-term sick leave due to psychiatric disorders, with regard to gender, age, socioeconomic status, and previous sickness absence. Methods The cohort included 4,891 employees in Sweden, who, in 1999 were aged 20–61 and had a new sick-leave spell >90 days with a psychiatric disorder. Retrospective and prospective registry data on sickness absence and DP for 1996–2002 were obtained. Logistic regressions were performed to estimate odds ratios (ORs) with 95% confidence intervals (CIs) for having a low, intermediate, or high level of sickness absence (<17, 17–90, and 91–365 days, respectively) or DP in 2002. Results The mean number of sick-leave days per person per year 3 years prior to inclusion was low; 17 days, but had increased to 211 days by 2000. In 2002, 26% had been granted DP, significantly higher rate among men, while a higher rate of the women had long-term sickness absence. Of all 4,891 subjects, 35% had <17 sick-leave days in 2002. The OR of having low, intermediate, or long-term sickness absence decreased with age. The reverse was found for obtaining DP, for which also low socioeconomic status was an independent predictor of an increased risk (OR = 3.40, CI 2.28–5.08). Conclusions Employees with long-term sick leave due to psychiatric disorders did not have a high level of sickness absence in the 3 years prior to inclusion in the study. Also, 3 years after inclusion, only 35% had very low levels of sickness absence, whereas 26% had been granted DP. Employees who were aged 55–61 showed the lowest risk of sick leave but the highest risk of DP. Low SES was a significant predictor of DP in 2002.     

Burnout in the general population

Background Burnout is a chronic stress syndrome which develops gradually as a consequence of prolonged stress situation. Socio-demographic factors related to job-related burnout have not been studied in the whole population. We investigated the relative differences in the level of burnout between groups based on various socio-demographic factors in the population-based Finnish sample. Methods The nationally representative sample comprised 3,424 employees aged 30–64 years. Burnout was assessed with the Maslach Burnout Inventory–General Survey. The socio-demographic factors of interest were gender, age, education, type of employment, work experience, socio-economic status (SES), working time, and marital status. Results Only small differences in burnout were found between the different population groups. As a three-dimensional syndrome, burnout was associated with age. In contrast to what has been consistently reported so far, mostly among human service work and in non-representative studies, burnout seemed to increase somewhat with age. Among women, burnout was also related to education, SES, and work experience, and among men, to marital status. Conclusions Burnout can evolve in all kinds of vocational groups. It seems that age does not generally protect against burnout. A low education level and low social status carry a possible risk of burnout for women, and being single, divorced, or widowed carry a possible risk of burnout for men.     

Social factors of sickness absences and ways of coping: a qualitative study of men and women with mental and musculoskeletal diagnoses,Norway

The rate of sickness absence is a serious problem in Norway and Scandinavia as a whole. Musculoskeletal problems are a heterogeneous category, covering a spectrum from a broken back and diffuse muscle pains. Mental diagnoses constitute generally about 25–30% of the total number of the long-term sickness absences. It is thus important to document scientifically how and why participation in nature–culture–health (NaCuHeal) activities may prove beneficial for individuals with long-term illnesses. The purpose of our project is to focus on and to discuss how social factors influence sickness absence. There were two aims of this study: (a) to explore and reveal the absentees' own experiences and perceptions of sickness absence in daily life and (b) to explore and reveal the absentees' own perceptions and experiences of various coping strategies while being on sickness absence. Qualitative method through a pragmatic synthesis of elements of ethnography and grounded theory were used. The sample from the county of Oppland, Norway (n = 30), had a mental or a musculoskeletal diagnosis in accordance with the ICPC-2 medical classification system. In this study, men and women understand and interpret their health situation differently; most men in this sample have become ill due to work-related factors, and for women it seems to be the combined impact of domestic responsibilities and job strain, the so-called double exposure. Health-promoting nature and culture activities refuel their energy levels, which in turn help them to sustain their social network. A combination of various social activities seemed also to be beneficial as long as these activities could be personally chosen within their own time and space. This notion highlights the importance of a lay perspective on the illness experience and its connections to coping strategies. Combined with discussion of sickness absence as a phenomenon, we believe that our findings can contribute to a wider understanding of sickness absence, the complexity behind the outbreak of long-term illnesses and ways of coping in everyday life. This research may add important knowledge and insight, hence increase awareness and understanding of NaCuHeal benefits among health personnel and rehabilitation.

Burnout as a risk factor for antidepressant treatment – a repeated measures time-to-event analysis of 2936 Danish human service workers

Burnout is a state of emotional exhaustion, feelings of reduced personal accomplishment, and withdrawal from work thought to occur as a consequence of prolonged occupational stress. The condition is not included in the diagnostic classifications, but is considered likely to develop into depressive disorder in some cases. We examined the prospective association between burnout and antidepressant treatment, as an indicator of clinically significant mental disorder. We further investigated potential effect-modifiers of the association, to identify factors that may prevent this progression of burnout. We used questionnaire data from a three-wave study of Danish human service workers conducted during 1999–2005, linked with national register data on purchases of antidepressants (ATC: N06A). We included 4788 observations from 2936 individuals (81% women) and analysed data by Aalens additive hazards modeling, examining the risk of entering antidepressant treatment in relation to the level of work-related burnout measured by the Copenhagen Burnout inventory. As effect-modifiers we examined both sociodemographic factors and a range of psychosocial work environment factors. The level of burnout predicted antidepressant treatment. This association was modified by sex (p < 0.01). In men, high vs. intermediate burnout was associated with a 5% increased risk of antidepressant treatment per year of follow-up. This risk difference was 1% for women. Due to the sex specific patterns, we restricted effect modification analyses to women. We found no effect-modification by the examined work environment factors, though a sensitivity analysis indicated a possible stronger association in women of lower occupational position. In conclusion, burnout predicted antidepressant treatment, with a stronger association in men than women. We found no evidence of effect-modification by any of the examined psychosocial work environment factors.     

Insomnia and sleep quality among primary care physicians with low and high burnout levels

OBJECTIVE: The aim of this study was to assess insomnia and sleep quality in primary care physicians with low and high burnout scores. METHODS: A representative sample of 240 physicians was drawn from 70 medical centers in Madrid, Spain. Based on quartile splits of the overall index of the Shirom-Melamed Burnout Questionnaire, 55 participants were allocated to a low-burnout group, and 58 were included in a high-burnout group. The questionnaire also included sociodemographic data, insomnia symptomatology, and the Pittsburgh Sleep Quality Index. RESULTS: Of the total sample, 18.8% met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for insomnia diagnoses. More individuals with high burnout scores (21.1%) than individuals with low burnout scores (6.9%) fulfilled these criteria. Results of multivariate logistic regression analyses showed that burnout was the only variable related to insomnia diagnoses (odds ratio=7.56; 95% confidence interval=2.38-14.02). Furthermore, the results of multivariate analysis of covariance, after adjustments for sociodemographic variables, indicated that subjects from the high-burnout group scored significantly higher than subjects from the low-burnout group on the global sleep quality index and its components, indicating significantly greater disturbed sleep for the former. CONCLUSION: The results of the present study provide support for a clear relationship between burnout and disturbed sleep, as shown by the high prevalence of insomnia and poor sleep quality among physicians with high levels of burnout.     

The epidemiology of chronic fatigue, physical illness, and symptoms of common mental disorders: a cross-sectional survey from the second British National Survey of Psychiatric Morbidity

OBJECTIVE: The study aimed to describe the prevalence of chronic fatigue in the general population and to investigate the extent to which its association with physical illness was independent of other symptoms of common mental disorders. METHODS: Data from the second British National Survey of Psychiatric Morbidity (2000) were analyzed. The survey covered people aged 16 to 74 years living in private households. Chronic fatigue (significant reported fatigue lasting 6 months or more) was ascertained using the revised Clinical Interview Schedule. Information on reported physical illness and sociodemographic factors was considered. Psychiatric symptoms were also assessed using the revised Clinical Interview Schedule. RESULTS: The prevalence of chronic fatigue was 15.0%, and this showed a significant association with the number of reported physical illnesses (odds ratio [OR] per reported illness, 1.79; 95% confidence interval, 1.68-1.90). It was higher in midlife, in women, in participants with less skilled occupations, and in those with lower educational attainment. Chronic fatigue was strongly associated with the presence of depressive symptoms (OR, 5.37), anxiety-related symptoms (OR, 4.66), and with sleep complaints (OR, 4.41). After adjustment for all sociodemographic and psychiatric factors, the number of reported physical illnesses was less strongly but still significantly associated with chronic fatigue (OR, 1.51; 1.39-1.63). CONCLUSION: Physical illness is strongly associated with chronic fatigue. Symptoms of common mental disorders are also associated with chronic fatigue, but the association between physical illness and chronic fatigue is evident even after adjusting for psychiatric symptoms. The assessment of physically ill people should include chronic fatigue and psychiatric symptoms.     

Long-term sickness absence and disability pension with psychiatric diagnoses: a population-based cohort study

Sickness absence certified with psychiatric diagnoses is increasing in many Western countries. A substantial proportion of the sickness absentees never return to work, but ends up with a permanent disability pension (DP). This study investigated the incidence of long-term sickness absence (LTSA) with different psychiatric diagnoses, and tested predictors of the transition to permanent DP. A special objective was to explore previously reported gender differences, using a population-based cohort study. The population at risk of LTSA was 106,674 occupational active men and 89,356 women in a Norwegian county in 1994; 314 women and 203 men with LTSA >8 weeks, certified with a psychiatric diagnosis, were followed to the end of 1999, with DP as the endpoint. Diagnoses on sickness certificates, age, gender and income were used as explanatory variables in Cox regression analysis. Annual incidence of LTSA with a psychiatric diagnosis was 7.0/1000/year for women and 3.8/1000 for men; 72% of the women and 50% of the men had a diagnosis indicating depression. During follow-up, 32% of the men and 25% of the women obtained DP. Increasing age, male gender, low income and a diagnosis of psychosis or "other" increased the DP risk. Separate analysis for men indicated a different effect of age and a larger role of serious mental illness. The study verified that women more often than men had LTSA with psychiatric diagnoses, especially with depression. Men were at higher risk of transition to DP, and the study suggested some possible explanations.     

Factors affecting disability in patients attending the internal medicine departments of general hospitals

The aim of this study was to investigate the effect of sociodemographic factors, physical factors and mental factors on the physical and social disability of patients attending outpatient clinics of general hospitals. Physical and psychiatric morbidity in 1580 consecutive patients attending the internal medicine department of general hospitals was assessed using a stratified two-stage sampling design method. Of the total, 336 patients completed the second stage interview composed of Primary Care Version of Composite International Diagnostic Interview and Groningen Social Disability Schedule to assess sociodemographic, physical and mental factors. In this study, restricted activity days, disability days and Brief Disability Questionnaire were used for the assessment of physical disability, and Groningen Social Disability Schedule was used for social disability. Sociodemographic, physical and mental factors were all related to disability. Among sociodemographic factors, unemployment was associated with physical disability and social disability mildly. Among physical factors, the severity of physical disease was not associated with disability and medically explained somatic symptoms were associated with disability. Furthermore, the mental factor was more strongly associated with physical and social disability. It could be said that the mental factor is more strongly associated with physical and social disability than sociodemographic or physical factors. In addition, even mild mental symptoms not leading to ICD-10 mental disorders affected disability. From the viewpoint of the patients' burden, it is important to assess the mental symptoms as well as physical status in outpatient clinics of internal medicine or primary care.     

Psychiatric disorders in homeless men and women in inner Sydney

OBJECTIVE: To determine the 12-month prevalence of mental disorders among homeless people in inner Sydney and compare this data with data collected on homeless populations in other Western cities. METHOD: Representative sample of 210 homeless men and women in Sydney were interviewed using the Composite International Diagnostic Interview (2.0). RESULTS: Seventy-three percent of men and 81% of women met criteria for at least one mental disorder in the past year and 40% of the men and 50% of the women had at least two mental disorders. The prevalence rate of schizophrenia among men and women was 23% and 46%, respectively. There was considerable comorbidity between mental disorders with one in five men (20%) and 29% of women meeting criteria for two mental disorders. The prevalence of any mental disorder is four times higher among homeless men and women in inner Sydney than within the Australian general population. International comparisons demonstrated significant cross-cultural differences in the prevalence of mental disorders among the homeless. CONCLUSIONS: This paper highlights the need for comparable epidemiological data when examining an international problem such as homelessness.     

The incidence of mental illness in early motherhood in a population-based survey

The present study examined the risk of mental disorders within the first 3 postpartum years in a nationally representative sample and the sociodemographic risk factors for mental illness in early motherhood. Women aged 18 to 55 years were asked, "Are you pregnant at this time?" at baseline. A total of 13,839 women answered, with 365 of these women reporting pregnancy. Mental disorders were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV version. After adjusting for sociodemographics, postpartum women were found to be at lower risk than non-postpartum women for having several first onset mental disorders (adjusted odds ratio range: 0.49-0.58). Postpartum women with a history of mental illness were at lower risk for the onset of any mental disorder (adjusted odds ratio: 0.60, 95% confidence interval: 0.39-0.91). No sociodemographic correlates of mental disorders were identified. Clinicians should be aware of these findings when counseling women about mental disorder risk postbirth.     

Burnout among direct-care staff members of facilities for persons with mental retardation in Japan

Using the Pines' Burnout Scale, we conducted the first nationwide survey in Japan to study burnout among 3,774 staff members in 216 social welfare facilities for persons with mental retardation. Mean burnout scores were significantly higher among direct-care staff members than among facility directors, middle managers, and other types of staff personnel. Burnout scores were significantly lower for staff members who reported having supervisors whom they could consult about work or personal problems than those who reported they could not. Findings suggest that supervisor support can reduce burnout among direct-care staff members at social welfare facilities for persons with mental retardation.     

Discrimination in health care against people with mental illness

This paper discusses factors associated with low rates of help-seeking and poorer quality of physical healthcare among people with mental illnesses. Evidence is reviewed on the associations between low rates of mental health literacy, negative attitudes towards people with mental illness, and reluctance to seek help by people who consider that they may have a mental disorder. People with mental illness often report encountering negative attitudes among mental health staff about their prognosis, associated in part with ‘physician bias’. ‘Diagnostic overshadowing’ appears to be common in general health care settings, meaning the misattribution of physical illness signs and symptoms to concurrent mental disorders, leading to underdiagnosis and mistreatment of the physical conditions.     

The relationship between body mass index and mental health

BACKGROUND: The association between atypical body weight and mental health remains poorly understood. We examined the relationship between body mass index and mental health in a population-based study of adults that included the full range of body weights, three disorder types, and three levels of mental illness severity. METHODS: Data came from the 2003 Alberta Mental Health Survey (n=5383), which included a validated, standard instrument for measurement of DSM-IV mental disorders as well as several indicators of psychiatric symptoms. Associations were examined using crosstabulation and chi squared statistics, and logistic regression adjusting for sociodemographic variables. RESULTS: Findings differed by type and severity of mental illness and by sex and age. For instance, anxiety disorders were elevated among underweight men compared to normal weight men and to women. Substance use disorders were elevated among obese men at younger compared to older ages. Mood disorders were elevated among obese women compared to normal weight women, and subclinical anxiety/depression was reduced among obese men compared to normal weight men and to women. CONCLUSIONS: These analyses highlight the importance of considering type of mental illness, level of severity, sex and age when examining the relationship between BMI and mental health. The diversity of patterns observed, detectable at the population level, warrant further examination and monitoring.     

Hostility and ill health: role of psychosocial resources in two contexts of working life

OBJECTIVE: The purpose of this study was to examine the extent to which increased risk to health problems in hostile employees is associated with psychosocial resources and life context. METHODS: Social relationships, job control, and sickness absence were assessed among 757 hostile and nonhostile municipal employees in two life contexts: during a stressful organizational downsizing; and during a period after the downsizing. The follow-up time was 550 person-years for men and 1677 person-years for women during the period of downsizing, and 519 person-years for men and 1568 person-years for women during the period after downsizing. RESULTS: The risk of sick leave was 1.2-1.4-fold higher in the hostile individuals than in the others. Small network size in hostile employees related to a 1.4-2.5-fold higher risk of sick leave compared to large network size. In nonhostile employees, network size did not associate with sick leave. Poor job control effected a 50% higher risk of sick leave in hostile than in nonhostile individuals during downsizing. During the less stressful period, both hostility and poorjob control increased absence rates independently of one another. Strong spouse support protected only nonhostile employees from sickness. No differences between hostile and nonhostile employees were found in the levels of psychosocial resources or changes in them. CONCLUSION: The risk of health problems in hostile persons could be linked with heightened vulnerability in poor psychosocial resource conditions and with the inability to benefit from existing psychosocial resources. Such personal deficits seem to be resource-specific and vary somewhat according to an individual's life context.
