Konferensbidrag (refereegranskat)abstract
- Main Abstract Content: Purpose To investigate the association between conflict frequency and bullying at T1 and T2, moderation of individual conflict management styles and mediation of negative acts. Methodology Data from the Workplace Bullying and Harassment cohort (2006-2008) were analysed cross-sectionally (n=3363) and longitudinally (n=1664). Measures: conflict frequency; three individual conflict management styles (Active-Constructive, Active-Destructive and Passive-Avoiding); the Negative Acts Questionnaire; being a target or perpetrator of bullying. All analyses were adjusted for gender, age, workplace fairness and supervisor’s conflict solving abilities. Results Cross-sectional findings: Higher conflict frequency was significantly associated with more negative acts and a higher risk of being a target or perpetrator. Among those higher in Passive-Avoidant conflict management style, there was a stronger association of conflict frequency with both negative acts and being a target or perpetrator. Longitudinal findings: Higher conflict frequency (T1) was associated with more negative acts (β=0.23, p<.001) and higher risk of being a target (β=0.13, p<.001) or perpetrator (β=0.11, p<.001) (T2). Passive-Avoidant conflict management style enhanced the association between conflicts and being a target of bullying (β=0.18, p<.01). The association between conflicts (T1) and being target or perpetrator (T2) was mediated by negative acts (T1). Limitations The associations were significant only in the cross-sectional analyses and in longitudinal analyses not adjusted for baseline levels of the outcome: Inferences about causality should be cautious. Practical implications Implementation of conflict management strategies should focus on the Active-Constructive style. Value: This is the first study testing 2-year associations between conflicts and bullying with negative acts as a mediator.

- Over the last decade, the technique of using ambulatory salivary sampling has become increasingly popular in field research and clinical studies. The non-invasive method is easy to administer and analyze and allows implmentation in large scale study designs. However, this large interest in the use of salivary cortisol measurement is paralleled with frustrations on opposing results. This presentation is based on a critical evaluation of the existing literature on salivary cortisol, aiming to evaluate the utility of salivary cortisol as a biomarker in various settings and how we can understand cortisol reactivity using evidence of experiences from different study designs. The work is compiled by the Scandinavian Stress and Cortisol Network, a network financed by the Swedish Research Council, and one main question asked was: is it possible that different results of studies involving cortisol assessments are functions of differences in the theoretical assumptions made and methods used. In particular, the symposium will focus on how the many different ways of evaluating levels and dynamics of salivary cortisol (i. e. with regard to time points of assessment and different algorithms based on multiple time points) may have an impact on the interpretation of cortisol measurements in various contexts. Salivary cortisol has been studied in relation to the following topics: demographic variables, psychosocial work environment, psychosocial resources (e.g. mastery) and outcomes (e.g. burnout), sleep quality, biological markers (markers of cardivascular risk, inflammation and metabolism) and somatic outcome.

- Objective: This study aimed to examine the onset of workplace bullying as a risk factor for BMI increase.Methods: Repeated biennial survey data from three Nordic cohort studies were used, totaling 46,148 participants (67,337 participant observations) aged between 18 and 65 who did not have obesity and who were not bullied at the baseline. Multinomial logistic regression was applied for the analysis under the framework of generalized estimating equations.Results: Five percent reported onset of workplace bullying within 2 years from the baseline. In confounder-adjusted models, onset of workplace bullying was associated with a higher risk of weight gain of >= 1 BMI unit (odds ratio = 1.09; 95% CI: 1.01-1.19) and of >= 2.5 BMI units (odds ratio = 1.24; 95% CI: 1.06-1.45). A dose-response pattern was observed, and those exposed to workplace bullying more frequently showed a higher risk (P-trend = 0.04). The association was robust to adjustments, restrictions, stratifications, and use of relative/absolute scales for BMI change.Conclusions: Participants with exposure to the onset of workplace bullying were more likely to gain weight, a possible pathway linking workplace bullying to increased long-term risk of type 2 diabetes.

- AIMS/HYPOTHESIS: The aim of this multicohort study was to examine whether employees exposed to social stressors at work, such as workplace bullying and violence, have an increased risk of type 2 diabetes.METHODS: The study included 45,905 men and women (40-65 years of age and free of diabetes at baseline) from four studies in Sweden, Denmark and Finland. Workplace bullying and violence were self-reported at baseline. Incident diabetes was ascertained through national health and medication records and death registers. Marginal structural Cox models adjusted for age, sex, country of birth, marital status and educational level were used for the analyses.RESULTS: Nine per cent of the population reported being bullied at work and 12% were exposed to workplace violence or threats of violence. Bullied participants had a 1.46 (95% CI 1.23, 1.74) times higher risk of developing diabetes compared with non-bullied participants. Exposure to violence or threats of violence was also associated with a higher risk of diabetes (HR 1.26 [95% CI 1.02, 1.56]). The risk estimates attenuated slightly when taking BMI into account, especially for bullying. The results were similar for men and women, and were consistent across cohorts.CONCLUSIONS/INTERPRETATION: We found a higher risk of incident type 2 diabetes among employees exposed to bullying or violence in the workplace. Further research is needed to determine whether policies to reduce bullying and violence at work may reduce the incidence of type 2 diabetes in working populations. Research on the mechanisms is also highly warranted.

- AimsTo assess the associations between bullying and violence at work and cardiovascular disease (CVD).Methods and resultsParticipants were 79 201 working men and women, aged 18–65 years and free of CVD and were sourced from three cohort studies from Sweden and Denmark. Exposure to workplace bullying and violence was measured at baseline using self-reports. Participants were linked to nationwide health and death registers to ascertain incident CVD, including coronary heart disease and cerebrovascular disease. Study-specific results were estimated by marginal structural Cox regression and were combined using fixed-effect meta-analysis. Nine percent reported being bullied at work and 13% recorded exposure to workplace violence during the past year. We recorded 3229 incident CVD cases with a mean follow-up of 12.4 years (765 in the first 4 years). After adjustment for age, sex, country of birth, marital status, and educational level, being bullied at work vs. not was associated with a hazard ratio (HR) of 1.59 [95% confidence interval (CI) 1.28–1.98] for CVD. Experiencing workplace violence vs. not was associated with a HR of 1.25 (95% CI 1.12–1.40) for CVD. The population attributable risk was 5.0% for workplace bullying and 3.1% for workplace violence. The excess risk remained similar in analyses with different follow-up lengths, cardiovascular risk stratifications, and after additional adjustments. Dose–response relations were observed for both workplace bullying and violence (Ptrend < 0.001). There was only negligible heterogeneity in study-specific estimates.ConclusionBullying and violence are common at workplaces and those exposed to these stressors are at higher risk of CVD.
