RESUMEN
BACKGROUND: Job insecurity has been associated with certain health outcomes. We examined the role of job insecurity as a risk factor for incident diabetes. METHODS: We used individual participant data from 8 cohort studies identified in 2 open-access data archives and 11 cohort studies participating in the Individual-Participant-Data Meta-analysis in Working Populations Consortium. We calculated study-specific estimates of the association between job insecurity reported at baseline and incident diabetes over the follow-up period. We pooled the estimates in a meta-analysis to produce a summary risk estimate. RESULTS: The 19 studies involved 140 825 participants from Australia, Europe and the United States, with a mean follow-up of 9.4 years and 3954 incident cases of diabetes. In the preliminary analysis adjusted for age and sex, high job insecurity was associated with an increased risk of incident diabetes compared with low job insecurity (adjusted odds ratio [OR] 1.19, 95% confidence interval [CI] 1.09-1.30). In the multivariable-adjusted analysis restricted to 15 studies with baseline data for all covariates (age, sex, socioeconomic status, obesity, physical activity, alcohol and smoking), the association was slightly attenuated (adjusted OR 1.12, 95% CI 1.01-1.24). Heterogeneity between the studies was low to moderate (age- and sex-adjusted model: I2 = 24%, p = 0.2; multivariable-adjusted model: I2 = 27%, p = 0.2). In the multivariable-adjusted analysis restricted to high-quality studies, in which the diabetes diagnosis was ascertained from electronic medical records or clinical examination, the association was similar to that in the main analysis (adjusted OR 1.19, 95% CI 1.04-1.35). INTERPRETATION: Our findings suggest that self-reported job insecurity is associated with a modest increased risk of incident diabetes. Health care personnel should be aware of this association among workers reporting job insecurity.

Prospective research on psychosocial effects on employees' health associated with organizational mergers has been scarce. The first aim of this study was to explore the subjective health effects (exhaustion and functional incapacity) of an organizational merger among employees who had experienced a change in their own job position differently (improved, unaltered, and declined). Secondly, the effects of pre-merger social support (organizational, supervisor, and coworkers) at work on the experienced change in job position and on subjective health were examined. The merger took place in 1999 between two multinational firms of equal size. The study is based on two surveys (n=2,225) carried out in 1996 and in 2000 in the Finnish part of the company. The data on age, sex, pre-merger sickness absence (1996-98) and subjective health status (1996) were used as covariates. The results indicate that all sources of social support had a significant effect on the experience of change in one's job position. A decline in job position strongly increased the risk of poor subjective health after the merger. Weak organizational support was associated with impaired subjective health, especially in blue-collar workers, while weak supervisor support impaired functional capacity in white-collar workers. In turn, strong co-workers' support increased the risk of poor subjective health among blue-collar workers when their job position declined. We conclude that negative changes experienced in one's job position and lack of upper-level social support at work create a potential risk for health impairment in different employee groups in merging enterprises.

The global recession has forced the Finnish forest industry to carry out major restructuring activities. Employees have faced different kinds of restructuring, mainly aimed at reducing staff and production. Many studies have shown the negative consequences of restructuring on employee well-being by using negative, ill-health indicators. Our aim is to examine the extent to which change appraisal influences both the negative and positive aspects of work-related well-being among employees who continue working in the organization after the restructuring process. We also examine the role of different actors (top management, immediate supervisor, employees themselves) in how the change is appraised. The study investigated blue-collar employees working in the Finnish forest industry during a period of extensive transition (2008-2009). All six participating factories underwent restructuring between baseline and the follow-up survey (n=369). After adjustment for gender, age and baseline well-being, negative change appraisal increased the risk of experiencing more stress and less work enjoyment. Negative change appraisals thus also damaged the positive, motivational aspects of employee well-being. The results showed the importance of offering employees the opportunity to participate in the planning of changes related to their work as regards positive change appraisal.

The Finnish forest industry has undergone extensive transition in recent years. This study investigates the effect of restructuring on the well-being of blue-collar employees who continued working in the organization after the changes. All six factories selected for the study were in the process of restructuring between baseline and the follow-up survey. The factories were grouped according to personnel reduction (dismissals): Change group 1 - no dismissals; and Change group 2 - dismissals. The majority of the analyses were carried out using longitudinal data (n=382). The associations between the changes in personnel and functional and psychological well-being were analysed using ANCOVA (adjusted for age, gender, education, and outcome at baseline). In both change groups the level of functional well-being improved after restructuring, but the level of psychological well-being decreased. The content of the changes, regardless of whether they involved personnel dismissals, did not affect the magnitude of the decrease in psychological well-being. It seems that the effect of restructuring on the psychological well-being of employees working in the restructuring organization is considerable, even when no dismissals are involved. The impact of change on functional well-being seems to be different.

OBJECTIVE: To determine the association between self reported job insecurity and incident coronary heart disease. DESIGN: A meta-analysis combining individual level data from a collaborative consortium and published studies identified by a systematic review. DATA SOURCES: We obtained individual level data from 13 cohort studies participating in the Individual-Participant-Data Meta-analysis in Working Populations Consortium. Four published prospective cohort studies were identified by searches of Medline (to August 2012) and Embase databases (to October 2012), supplemented by manual searches. REVIEW METHODS: Prospective cohort studies that reported risk estimates for clinically verified incident coronary heart disease by the level of self reported job insecurity. Two independent reviewers extracted published data. Summary estimates of association were obtained using random effects models. RESULTS: The literature search yielded four cohort studies. Together with 13 cohort studies with individual participant data, the meta-analysis comprised up to 174,438 participants with a mean follow-up of 9.7 years and 1892 incident cases of coronary heart disease. Age adjusted relative risk of high versus low job insecurity was 1.32 (95% confidence interval 1.09 to 1.59). The relative risk of job insecurity adjusted for sociodemographic and risk factors was 1.19 (1.00 to 1.42). There was no evidence of significant differences in this association by sex, age (<50 v ≥ 50 years), national unemployment rate, welfare regime, or job insecurity measure. CONCLUSIONS: The modest association between perceived job insecurity and incident coronary heart disease is partly attributable to poorer socioeconomic circumstances and less favourable risk factor profiles among people with job insecurity.

BACKGROUND: Prospective studies on the relationship between organisational merger and mental health have been conducted using subjective health indicators. The objective of this prospective occupational cohort study was to examine whether a negative change during an organisational merger is an independent predictive factor of psychiatric morbidity. METHOD: Survey data on organisational characteristics, health and other factors were collected prior to (1996) and after the merger (2000); register data on psychiatric morbidity were collected at baseline (1/1/1994-30/9/2000) and during the follow-up (1/10/2000-31/12/2005). Participants were 6511 (77% men) industrial employees aged 21-65 years with no register-based diagnosed psychiatric events prior to the follow-up (the Still Working Study). During the follow-up, 252 participants were admitted to the hospital due to psychiatric disorders, were prescribed a psychotropic drug or attempted or committed suicide. RESULTS: A negative self-reported change in the work organisation during the merger was associated with increased risk of postmerger psychiatric event (HR 1.60, 95% CI 1.19 to 2.14). This association was independent of mental health-related factors measured before the merger announcement, such as demographic characteristics, occupational status, personal orientation to life, self-rated health, self-reported psychiatric morbidity or chronic disease. CONCLUSION: A negative change in work organisation during an organisational merger may elevate the risk for postmerger psychiatric morbidity.

OBJECTIVE: To examine the impact of sense of coherence (SOC) on psychiatric events in the context of organizational merger. METHODS: Data were derived from a prospective "Still Working" study using questionnaire and health register data. The study population (n = 4279) consisted of employees with no psychiatric events prior to the 5-year mental health follow-up. RESULTS: Employees with a weaker premerger SOC were at a higher risk of perceiving the organizational change negatively (odds ratio = 1.83, 95% CI: 1.57 to 2.14) and had an elevated risk of postmerger psychiatric events (hazard ratio = 1.42, 95% CI: 1.04 to 1.94). A stronger SOC decreased the adverse effect of negative appraisal of change on psychiatric events. CONCLUSIONS: A strong premerger SOC seems to be a protective factor for mental health when the employee experiences negative changes during an organizational merger.
