Effects of stable and changing demand-control histories on worker health

OBJECTIVES: The present study examined effects of stability and change in exposure to job demands and job control (demand-control histories) in relation to the strain hypothesis of Karasek's demand-control model. METHODS: The hypotheses [(i) high (low) levels of ill health were expected for workers exposed to stable 1 levels of high (low) job demands and low (high) job control; (ii) decreases (increases) in strain-related health outcomes were expected for workers with positive (negative) changes in job demands and job control; (iii) workers reporting major changes in job demands or control were expected to report more "objective" job changes] were tested with a group-by-time analysis of variance using data from a four-phase Dutch cohort study on musculoskeletal disorders, absenteeism, stress, and health. Associations between demand-control histories and job changes were tested in a log-linear analysis. RESULTS: The hypotheses for the stable exposure groups were supported for depression and job satisfaction. Those for positive and negative changes were partially supported. There was no relation, however, between the level of stability or changes in exposure to demands and control for the registered duration and frequency of sickness absence. Finally, the results showed that workers reporting major changes in demand-control histories over time had more job changes, and those reporting job changes towards high strain jobs evaluated the changes as more distressful. CONCLUSIONS: This longitudinal study supports the strain hypothesis of the demand-control model and shows a significant association between major changes in demand-control histories and job changes.     

Job stress and cardiovascular risk factors in male workers

BACKGROUND: This study examined whether job stress (work demand and decision latitude) is associated with smoking, blood pressure, lipid level (total cholesterol, triglyceride, HDL cholesterol), and homocystein as risk factors for cardiovascular disease in Korean male workers. METHODS: Study subjects of this study were recruited from a sample of 1,071 workers in 20 companies of W city and H counties, and they were grouped into four categories (high strain group, active group, passive group, and low strain group) based on the postulation of Karasek's Job Strain Model. Of them, we invited 160 male workers (40 people each subgroup) using a stratified sampling, and finally, 152 eligible participants were analyzed. RESULTS: In multivariate analyses, we found that decision latitude was associated with cholesterol, triglyceride, and homocystein and that work demand was related to smoking and systolic blood pressure. Job strain (the combination of high work demand with low decision latitude) was significantly related to higher levels of homocystein after controlling for age, BMI, smoking, and social support at workplace. CONCLUSIONS: These results indicate that job stress is associated with cardiovascular risk factors and might contribute to the development of cardiovascular disease. Some considerations for the future research were discussed.     

The association of the reporting of somatic symptoms with job stress and active coping among Japanese white-collar workers

To assess the associations between job stress and somatic symptoms and to investigate the effect of individual coping on these associations. In July 2006, a cross-sectional study was conducted during a periodic health check-up of 185 Japanese male office workers (21-66 yr old) at a Japanese company. Job stress was measured by job demand, control, and strain (=job demand/control) based on the Job Content Questionnaire (JCQ). Major somatic symptoms studied were headache, dizziness, shoulder stiffness, back pain, shortness of breath, abdominal pain, general fatigue, sleep disturbance, and skin itching. Five kinds of coping were measured using the Job Stress Scale: active coping, escape, support seeking, reconciliation, and emotional suppression. Comorbidities of hypertension, diabetes, obesity, depression, and anxiety were also evaluated. The most frequently cited somatic symptom was general fatigue (66%), followed by shoulder stiffness (63%) and sleep disturbance (53%). Of the five kinds of coping, only "active coping" was significantly and negatively associated with the number of somatic symptoms. The generalized linear models showed that the number of somatic symptoms increased as job strain index (p=0.001) and job demand (p=0.001) became higher, and decreased as active coping (p=0.018) increased, after adjusting for age and comorbidities. There was no statistical interaction among active coping, the number of somatic symptoms, and the three JCQ scales. Reporting somatic symptoms may be a simple indicator of job stress, and active coping could be used to alleviate somatization induced by job stress.     

Types of employment and health: analysis of the Second European Survey on Working Conditions

OBJECTIVES: To investigate the relationships among types of employment and several health self-perceived outcomes in a sample of active workers from the 15 state members of the European Union. METHODS: Cross-sectional study with data drawn from the Second European Survey on Working Conditions (n = 15,146 individuals). The predictive variable was the types of employment aggregated in: permanent workers, sole traders, small employers (less than 10 employees) and temporary workers (full-and part-time). Unconditional logistic regression models were adjusted by age, gender and several indications of working conditions. Permanent workers was used as the baseline category. RESULTS: Employees with permanent (69,3%) and temporary (12,5%) contracts notified the highest level of a job absenteeism while temporary employees reported the highest level of job dissatisfaction. On the other hand, sole traders (12,2%) and small employees (6.1%) notified the most frequent level of overall fatigue, backache and muscular pains. Having permanent workers as baseline category, temporary employees was associated with high dissatisfaction (OR = 1.68), and and overall fatigue (OR = 1.16), but with lower frequency of stress (OR = 0.74) and job absenteeism (OR = 0.87). Small employers showed a low frequency of absenteeism (OR = 0.68), but a high stress (OR = 1.77) and overall fatigue (OR = 1.27). Finally, sole traders reported more frequently overall fatigue (OR = 1.40), and stress (OR = 1.33), but less job absenteeism (OR = 0.58). CONCLUSIONS: These findings suggest that types of employment may have an independent effect on several health self-perceive outcomes. Further research is necessary to overcome various shortcoming of this study, and to assess the role either job security or level of income and social protection.     

Association between job stress and depression among Japanese employees threatened by job loss in a comparison between two complementary job-stress models.

OBJECTIVES: This study compared the separate effects produced by two complementary stress models--the job demand-control model and the effort-reward imbalance model--on depression among employees threatened by job loss. METHODS: A cross-sectional analysis was conducted to examine these associations among 190 male and female employees who responded to a self-administered questionnaire in a small Japanese plant with economic hardship. The employees were engaged in 2 job types--direct assembly line and indirect supportive tasks--and the latter was threatened by job loss because of downsizing. Independent variables were measured by the Japanese versions of Karasek's demand-control questionnaire and Siegrist's effort-reward imbalance questionnaire. Depression was assessed by the Center for Epidemiologic Studies Depression Scale. RESULTS: The employees with indirect supportive tasks (target for downsizing) were more likely to have depressive symptoms than direct assembly-line workers. Job strain, a combination of high demand and low control at work, was more frequent among the latter, while the combination of high effort and low reward was more frequent among the former. After adjustment for work environment factors, low control [odds ratio (OR) 4.7], effort reward imbalance (OR 4.1), and overcommitment (the person characteristic included in the effort-reward imbalance model) (OR 2.6) were independently related to depression. There is some indication that these effects were particularly strong in the subgroup suffering from potential job loss. CONCLUSIONS: This study confirms that the 2 job stress models identify different aspects of stressful job conditions. Moreover, effort-reward imbalance and low control at work are both associated with symptoms of depression.     

Job strain and leisure-time physical activity in female and male public sector employees

BACKGROUND: High work stress could decrease physical activity but the evidence of the relationship has remained equivocal. The present study examined the association between job strain and leisure-time physical activity in a large sample of employees. METHODS: Cross-sectional data related to a cohort of 46,573 Finnish public sector employees aged 17-64 years. Job strain was measured by questions derived from Karasek's Demand/Control model. Leisure-time physical activity was defined using activity metabolic equivalent task (MET) index. Analysis of variance was used to compare means of MET-hours/week by job strain categories and by tertiles of job control and job demands. RESULTS: Women and men with high strain (low control and high demands), passive jobs (low control and low demands), and low job control had 2.6 to 5.2 MET-hours/week less than their counterparts with low strain and high control, respectively, even after the effects of age, marital status, socioeconomic status, job contract, smoking, heavy drinking, and trait anxiety were taken into account. Active jobs (high control and high demands) were additionally associated with lower mean of MET-hours in men and in older workers. CONCLUSIONS: Our findings suggest an independent, albeit substantially weak, association between higher work stress and lower leisure-time physical activity.     

The relationship between perceived stress and self-reported illness-related absenteeism

PURPOSE: To investigate the association between perceived stress and illness-related work absenteeism. DESIGN: A standardized health profile questionnaire developed by Johnson & Johnson Advanced Behavioral Technologies, Inc., was used to collect demographic and personal health data between June 1988 and January 1993. Chi-square, odds ratio, and stepwise regression tests were used to analyze perceived stress and self-reported absenteeism data. SETTING: Worksite health promotion programs in 250 U.S. companies. SUBJECTS: Subjects consisted of 79,070 employees. MEASURES: Stress data, grouped as low, moderate, and high, were correlated with absenteeism data grouped by annual days missed (None, 1 to 2, 3 to 4, and 5+). RESULTS: Significant relationships were found (p < or = .05) between high stress and absenteeism for both genders. Female workers reported higher stress levels and absenteeism than men. Those with high stress were 2.22 more likely to be absent 5+ days per year than those with low stress. Work, finances, and family were the highest stress sources. Greatest absenteeism predictors were health, legal, social, and financial stress. CONCLUSIONS: These data primarily represented self-selected white workers and may not apply to all employees. However, if high stress relates to absenteeism, these data may provide valuable information for program design in stress management.     

Mental health and stress in the workplace: the case of general practice in the UK

This study adopted a 'workforce' perspective in a study of job strain in primary care (general practice) in the UK. It explored the level of stress amongst workers in general practice and between practices and examined the relationship between level of stress and work characteristics. Postal questionnaires were sent to a random sample of general practices (n = 81) in southern England. The study showed that 23% of all responders could be classified, according to the GHQ-12, as suffering from mental distress with practice managers having the highest level of stress and clerical and administrative staff the lowest. Work characteristics as measured by Karasek's Job Content Instrument were shown to be significant predictors of job stress as were marital status and health status. The implications of these findings are discussed, particularly focusing on the value of the job strain model for explaining job stress in general practice.     

Analysis of job stress in workers employed by three public organizations in Serbia

Objectives

The present study analyzes job stress in terms of education, age and the presence of cardiovascular and endocrine/metabolic diseases.

Material and Methods

A total of 411 workers employed by three public organizations completed the Job Content Questionnaire to classify their jobs based on the job strain model. Data about health condition, education and habits was obtained by the use of medical examinations and an interview.

Results

The analysis of the completed Job Content Questionnaires indicates that workers with high education have significantly higher decision latitude (DL) than low-educated workers (one-way ANOVA, p < 0.0001). DL was also different between age groups (one-way ANOVA, p < 0.0001) — the highest DL values were observed in the oldest group, while the lowest DL mean was found in the youngest group. Psychological job demands (PJD) and social support (SS) were not significantly different between educational and age groups. The frequency of job stress categories was significantly different between low and highly-educated workers (χ² test, df = 3, p < 0.0001) and also between different age groups (χ² test, df = 6, p < 0.0001). The majority of highly-educated men were exposed to “active” jobs (high PJD and high DL). Most frequently, men older than 45 years experienced jobs with high DL (“active“ and “low strain“), men aged 35 to 45 years were exposed to jobs with high PJD (“high strain” and “active”) while the majority of men younger than 35 years were exposed to jobs with low DL (“high strain” and “passive”). No association between cardiovascular and endocrine/metabolic disorders and different job stress categories was observed.

Conclusion

“High strain” and “passive” jobs were most frequently identified among low-educated and young men. Despite the absence of association between job stress and cardiovascular and endocrine/metabolic diseases, we recommend prevention of work stress, particularly in the case of low-educated workers and workers younger than 45 years exposed to unfavorable job stress categories.

Psychosocial Work Characteristics Predict Cardiovascular Disease Risk Factors and Health Functioning in Rural Women: The Wisconsin Rural Women''s Health Study

BACKGROUND: The aim of the present study is to investigate the association between psychosocial work characteristics and health functioning and cardiovascular disease risk factors among rural women of central Wisconsin and compare psychosocial work characteristics between farm and nonfarm women. METHODS: Stratified sampling was used to select a random sample (n = 1500) of farm and nonfarm women aged 25 to 71 years from the Central Marshfield Epidemiologic Study Area. The baseline examination included measurements of blood pressure, height, weight, and fasting blood lipids, glucose, and insulin. Psychosocial job condition was measured with the Karasek Job Content Questionnaires (JCQ). Health functioning was assessed by the Short Form-36 Health Survey. RESULTS: The analysis of JCQ showed that nonfarm residents were more likely to have jobs with high demand and high decision latitude compared to farm residents. Also, the farm residents (40.3%) were more likely to be occupied in passive jobs (jobs with low levels of demand and control) than the nonfarm residents (26.9%). Among farm residents, psychological job demand was associated with HDL level (beta = 0.17), triglycerides (beta = 0.0), their ratio (beta = 0.005), and blood insulin level (beta = 0.014), and among nonfarm residents, psychological job demand was associated with diastolic blood pressure (beta = 0.17) and total cholesterol level (beta = 0.002). CONCLUSION: Our results showed that rural farm residents had a higher prevalence of CVD risk factors and were more likely to be occupied in jobs with low levels of demand and control. Job stress predicted more CVD risk factors among farm residents compared to nonfarm residents. Therefore, interventions reducing job strain among rural farm residents are timely and necessary.     

Relation between job strain and myocardial infarction: a case-control study

OBJECTIVES: To study the influence of different job related and socioeconomic factors for development of myocardial infarction (MI). METHOD: The study was a case-control study of 76 male wage earners who had been admitted to hospital with MI. As a control group 176 male wage earners not admitted to hospital who were residents of the same county were used. Both groups were interviewed with an extensive questionnaire on job related conditions. Several indices on job related psychosocial factors were established in accordance with Karasek's job strain model as well as the extension of the model, the isostrain model. RESULTS: The most significant findings were consistent with Karasek's job strain model in that mean with a high degree of demand combined with a low degree of control at work had a significantly increased odds ratio (OR) 95% confidence interval (95% CI) of 2.1 (1.2 to 3.8) for MI after adjustment for age compared with men with a low degree of demand and a high degree of control at work. Further adjustment for smoking, socioeconomic status, employment sector, job category, and social network did not affect the OR substantially (OR 2.3 (1.2 to 4.4)). Other factors significantly associated to MI were job category (blue collar workers v white collar workers, OR 2.8 (1.6 to 5.8)), and employment sector (private v public, OR 3.1 (1.8 to 6.1)). CONCLUSIONS: Thus, the study confirmed the job strain model as well as the well known association between socioeconomic status and risk of MI, whereas the finding of an increased risk among employees in the private sector has not previously been described.

 

     

Perceived job stress and mental health in precision machine workers of Japan: a 2 year cohort study

OBJECTIVES: To determine whether perceived job stress affects mental health in occupational settings. METHODS: A 2 year cohort study was conducted. Initially, a survey including the general health questionnaire (GHQ) and a questionnaire about perceived job stress was carried out. Of 462 workers who initially showed a GHQ score of < or = 7,310 were successfully followed up for 2 years. The 2 year risks of developing mental ill health (a GHQ score > or = 8) were assessed relative to perceived job stress. To control for potential confounding factors, multiple logistic regression analyses were conducted. RESULTS: The overall 2 year risk for developing mental ill health was high at 57.7%. Workers who reported aspects of perceived job stress showed a greater 2 year risk than those without stress. Multiple logistic regression analyses showed that some components of perceived job stress were associated with a higher 2 year risk, among which "not allowed to make mistakes" showed the largest adjusted odds ratio (OR) (95% confidence interval (95% CI) of 2.37 (1.32 to 4.29). "Poor relationship with superior" had a significant effect on mental health only in women, with an adjusted OR (95% CI) of 3.79 (1.65 to 8.73). CONCLUSIONS: Certain specific items of perceived job stress seem to be associated with mental ill health in workers. These could broadly be described as job strain, or job demand items. The type of job stress that predicts mental health may be dependent on the characteristics of the workplace investigated.

How do types of employment relate to health indicators? Findings from the Second European Survey on Working Conditions

STUDY OBJECTIVE: To investigate the associations of various types of employment with six self reported health indicators, taking into account the part played by demographic variables, individual working conditions and four ecological indicators at the country level. DESIGN: Cross sectional survey (structured interview) of a sample of the active population of 15 European countries aged 15 years or over. Main independent variables were nine types of employment categorised as follows: small employers, full and part time permanent employees, full and part time fixed term employees, full and part time sole traders and full and part time temporary contracts. Main outcome measures were three self reported health related outcomes (job satisfaction, health related absenteeism, and stress) and three self reported health problems (overall fatigue, backache, and muscular pains). Logistic regression and multilevel models were used in the analyses. SETTING: 15 countries of the European Union. PARTICIPANTS: 15 146 employed persons aged 15 or over. MAIN RESULTS: Precarious employment was consistently and positively associated with job dissatisfaction but negatively associated with absenteeism and stress (as compared with full time permanent workers). Fatigue, backache and muscular pains also tended to be positively associated with precarious employment, particularly with full time precarious employment. Small employers reported high percentages of stress and fatigue, but absenteeism was relatively low. Sole traders generally reported high percentages of all outcomes, except for absenteeism, which was low. For each type of employment (except temporary contracts), full time workers tended to report worse health outcomes than part time workers. Patterns were generally consistent across countries. Associations persisted after adjustment for individual level working conditions and were not modified by country level variables. CONCLUSIONS: This study is the first to examine the relations between various types of employment and six health related indicators for all 15 member states of the European Union. Suggestive patterns worthy of further exploration have been found. Standardised definitions of types of underemployment and health related outcomes, more potent epidemiological designs and the inclusion of socioeconomic information (for example, social security systems, incapacity benefit schemes) at the regional level are proposed for inclusion in further research.     

Psychosocial job characteristics and risk of mortality in a Japanese community-based working population: the Jichi Medical School Cohort Study

We prospectively investigated the association between psychosocial job characteristics according to the job demand-control model and the risk of mortality in a Japanese community-based working population. A baseline examination conducted from 1992 to 1995 determined the socioeconomic, behavioural, and biological risks in addition to the psychosocial job characteristics of 3178 male and 3331 female workers aged 65 and under and free from cancer and cardiovascular diseases. During the 9-year follow-up study, 157 men and 64 women died. In the follow-up, the results of Cox proportional hazards regression analysis revealed that men with concurrent high job demands and high job control (an active job) had the lowest risk of mortality from all causes. Compared with the low demand and high control job category, the multivariate relative risk of an active job was 0.53 (95% confidence interval: 0.31, 0.89). This finding appeared largely attributable to a reduction in cancer mortality. Job characteristics were not associated with cardiovascular diseases or external causes of mortality. For women, no significant associations were observed. The findings suggest that an active job has a beneficial effect on the health of Japanese male workers. Investigating of the effect of psychosocial job characteristics on cancer might therefore provide valuable insights into the health of workers.     

Work organization and musculoskeletal injuries among a cohort of health care workers

OBJECTIVES: This study investigated the relationship between work-organization factors (job control, job demands, and workload measures) and the risk of lower-body musculoskeletal injury among health care workers. METHODS: A four-year, retrospective cohort study of 3769 health care workers was carried out in one acute care hospital in the Canadian province of British Columbia. A job-exposure matrix was constructed for the work-organization factors from survey and administrative data and assigned to workers on the basis of their occupation and department of employment. Musculoskeletal injuries resulting in workers' compensation claims were ascertained from the injury database of the hospital's Occupational Health and Safety Department. RESULTS: In the final Poisson models adjusted for demographic and biomechanical factors, an increased risk for compensated musculoskeletal injuries of the lower back and lower limb was related to low job control [relative risk (RR) 1.64, 95% confidence interval (95% CI) 1.08-2.49] and workload defined by working during periods of high absenteeism within a department (RR 2.10, 95% CI 1.61-2.98). The risk also increased with more biomechanical demands in an occupation and with a recent previous injury. CONCLUSIONS: The results indicate that work-organization characteristics (job control and workload) were associated with an increased risk of musculoskeletal injuries resulting in a compensation claim. These associations remained after the effect of demographic and biomechanical factors was taken into consideration. The association with workload measured by departmental levels of absenteeism should be explored further in future studies as reverse causality (musculoskeletal symptoms resulting in absenteeism) could not be fully ruled out in the current study.     

Job strain and sickness absence among nurses in the province of Québec

BACKGROUND: Using Karasek's job strain model, the objective of the study was to determine whether nurses exposed to job strain had a higher incidence of sick leave than nurses not exposed. METHODS: The design was longitudinal. Data on sick leave were collected for 1,793 nurses for a 20-month period: short-term leaves and certified sick leaves. The Job Content Questionnaire was used to measure psychological demands, job decision latitude, and social support at work. RESULTS: Short-term sick leaves were associated with job strain (incidence density ratio (IDR) = 1.20) and with low social support at work (IDR = 1.26). Certified sick leaves were also significantly associated with low social support at work (IDR = 1.27 for all diagnoses and IDR = 1.78 for mental health diagnoses). CONCLUSIONS: Our results support the association between job strain and short-term sick leaves. The association with certified sick leaves is also significant for subgroups of nurses with specific job characteristics. Social support at work, although associated with all types of sick leaves measured, does not modify the association between job strain and absence.     

Job control, job demands, social support at work and health among adolescent workers

OBJECTIVE: To evaluate physical and psychological dimensions of adolescent labor (such as job demands, job control, and social support in the work environment), and their relation to reported body pain, work injuries, sleep duration and daily working hours. METHODS: A total of 354 adolescents attending evening classes at a public school in Sao Paulo, Brazil, answered questionnaires regarding their living and working conditions (Karasek's Job Content Questionnaire, 1998), and their health status. Data collection took place in April and May 2001. Multiple logistic regression analysis was used to determine relations among variables. RESULTS: Psychological job demands were related to body pain (OR=3.3), higher risk of work injuries (OR=3.0) and reduced sleep duration in weekdays (Monday to Thursday) (p<0.01). Lower decision authority in the workplace (p=0.03) and higher job security (p=0.02) were related to longer daily working hours. CONCLUSIONS: It was concluded that besides physical stressors, psychological factors are to be taken into account when studying adolescent working conditions, as they may be associated with negative job conditions and health effects.     

Relationship between psychosocial job satisfaction and health in white collar workers

OBJECTIVE: To identify whether psychosocial satisfaction at work is associated with workers' health and to verify if sociodemographic characteristics have an impact on these associations. METHODS: A cross-sectional study was carried out in 224 employees of a private managed care and retirement savings company in S?o Paulo, Brazil. Four self-administered questionnaires on sociodemographic features, job satisfaction, and health (physical, mental, and work ability) were applied. Variables associations were analyzed using t-Student, Mann-Whitney and Kruskal-Wallis tests, Spearman correlation coefficient, and multiple linear regression analysis. RESULTS: Job satisfaction was associated with duration in the company (p <0.001) and job position (p=0.003), where greater satisfaction was observed among workers with shorter duration in the company and those in managing positions. Job satisfaction was associated with mental health and work ability (vitality: p<0.001; social aspects: p=0.055; emotional aspect: p=0.074; mental health: p<0.001; and work capacity: p=0.001). CONCLUSIONS: Job satisfaction is associated with workers' health regarding their "mental health" and "work ability", showing the importance of psychosocial factors for their health and well-being. Changes are suggested in work conception and organization to focus psychosocial factors. Longitudinal studies are recommended to investigate the causal direction of these associations.
