- Objective: This study investigated the association between occupational physical activity (OPA) and resting blood pressure in a cohort of Swedish construction workers.Methods: The final sample included 241,176 male construction workers. Occupations with low OPA were foremen and white-collar workers. The most frequent occupations in the medium OPA group were electricians, pipe workers, and machine operators, and in the high OPA group woodworkers, concrete workers, and painters.Results: Mixed effects models showed higher systolic and lower diastolic blood pressure with higher OPA, but the associations varied depending on the year of participation and participant age as shown by significant interaction terms (OPA*age, OPA*calendar year, age*calendar year). Age-stratified linear regression analyses showed a pattern of slightly higher systolic (1.49, 95% confidence interval: 1.08-1.90 mmHg) and lower diastolic (0.89, 95% confidence interval: 0.65-1.13 mmHg) blood pressure when comparing low with high OPA, but not among the oldest age groups.Conclusion: Despite a rather large contrast in OPA, the differences in systolic and diastolic blood pressure according to OPA were small.

Tidskriftsartikel (refereegranskat)abstract
- An accurate rating of hand activity and force is essential in risk assessment and for the effective prevention of work-related musculoskeletal disorders. However, it is unclear whether the subjective ratings of workers and observers correlate to corresponding objective technical measures of exposure. Fifty-nine workers were video recorded while performing a hand-intensive work task at their workplace. Self-ratings of hand activity level (HAL) and force (Borg CR10) using the Hand Activity Threshold Limit Value(& REG;) were assessed. Four ergonomist observers, in two pairs, also rated the hand activity and force level for each worker from video recordings. Wrist angular velocity was measured using inertial movement units. Muscle activity in the forearm muscles flexor carpi radialis (FCR) and extensor carpi radialis (ECR) was measured with electromyography root mean square values (RMS) and normalized to maximal voluntary electrical activation (MVE). Kendall's tau-b correlations were statistically significant between self-rated hand activity and wrist angular velocity at the 10th, 50th, and 90th percentiles (0.26, 0.31, and 0.23) and for the ratings of observers (0.32, 0.41, and 0.34). Significant correlations for force measures were found only for observer-ratings in five of eight measures (FCR 50th percentile 0.29, time > 10%MVE 0.43, time > 30%MVE 0.44, time < 5% -0.47) and ECR (time > 30%MVE 0.26). The higher magnitude of correlation for observer-ratings suggests that they may be preferred to the self-ratings of workers. When possible, objective technical measures of wrist angular velocity and muscle activity should be preferred to subjective ratings when assessing risks of work-related musculoskeletal disorders.

- We compared hand activity and force ratings in women and men doing identical hand-intensive work tasks. Musculoskeletal disorders are more common in women and hand-intensive work leads to an increased risk of these disorders. Knowledge of the gender influence in the rating of work exposure is lacking. The aim of this study was to investigate whether women and men performing identical hand-intensive work tasks were equally rated using hand activity and normalized peak force levels with the Hand Activity Threshold Limit Value((R)). Fifty-six workers participated, comprising 28 women-men pairs. Four observers-two woman-man pairs-were also involved. Self-ratings and observers' ratings of hand activity and force level were collected. The results of these ratings showed no significant gender differences in self-rated hand activity and force, as well as observer-rated hand activity. However, there was a significant gender difference in the observer-rated force, where the women were rated higher (mean (SD): women 3.9 (2.7), men 3.1 (1.8) (p = 0.01)). This difference remained significant in the adjusted model (p = 0.04) with grip strength and forearm-finger anthropometrics. The results provide new insights that observers' estimates of force can be higher in women compared with men in the same work tasks. Force should be further investigated and preferably compared to objective measurements.

Aerobic training for improved memory in patients with stress-related exhaustion : a randomized controlled trial
- 2017
-
Ingår i: BMC Psychiatry. - : BioMed Central. - 1471-244X. ; 17:1
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Patients with stress-related exhaustion suffer from cognitive impairments, which often remain after psychological treatment or work place interventions. It is important to find effective treatments that can address this problem. Therefore, the aim of this study was to investigate the effects on cognitive performance and psychological variables of a 12-week aerobic training program performed at a moderate-vigorous intensity for patients with exhaustion disorder who participated in a multimodal rehabilitation program.METHODS: In this open-label, parallel, randomized and controlled trial, 88 patients diagnosed with exhaustion disorder participated in a 24-week multimodal rehabilitation program. After 12 weeks in the program the patients were randomized to either a 12-week aerobic training intervention or to a control group with no additional training. Primary outcome measure was cognitive function, and secondary outcome measures were psychological health variables and aerobic capacity.RESULTS: In total, 51% patients in the aerobic training group and 78% patients in the control group completed the intervention period. The aerobic training group significantly improved in maximal oxygen uptake and episodic memory performance. No additional improvement in burnout, depression or anxiety was observed in the aerobic group compared with controls.CONCLUSION: Aerobic training at a moderate-vigorous intensity within a multimodal rehabilitation program for patients with exhaustion disorder facilitated episodic memory. A future challenge would be the clinical implementation of aerobic training and methods to increase feasibility in this patient group.TRIAL REGISTRATION: ClinicalTrials.gov: NCT03073772 .

- It is important to understand how people with exhaustion disorder (ED) perceive interventions aiming to facilitate cognitive functioning. Therefore, the overall aim of this study was to explore experiences from persons with ED after participating in a 12-week intervention of either computerized cognitive training or aerobic training. Both interventions were performed in addition to a multimodal rehabilitation programme. Thirteen participants, 11 women and 2 men, were interviewed about pros and cons with participating in the training. The interviews were analysed with Qualitative Content Analysis. The analyses resulted in the theme hopeful struggling for health and the categories support, motivation and sensations. It was hard work recovering from ED. Support from others who are in the same situation, family members, and technology and routines for the training were strongly emphasized as beneficial for recovery. Timing, i.e., matching activities to the rehabilitation programme, getting feedback and perceiving joy in the training were important for motivation. Participants in both interventions experienced positive sensations with improved memory performance, everyday life functioning and increased faith in the prospect of recovery. However, it is important to consider various aspects of support and motivation in both computerized cognitive training and aerobic training to enable participants to pursue their participation.

- Background: Stress is a commonly perceived cause of cancer, but the evidence to date is limited and inconclusive. We examined work-related stress in relation to cancer incidence in a population-based cohort, with outcome data from Swedish national registries.Methods: The study population included 113,057 participants in the Västerbotten Intervention Programme. HRs were estimated using Cox proportional hazards regression, for cancer overall and for types with ≥500 cases, and adjusting for several potential confounders. The primary exposure was prediagnostic work-related stress, using the well established Karasek job demand/control model. Demand and control variables were dichotomized at the median, and participants were classified according to combinations of these categories. We also considered social network and aspects of quality of life.Results: "High-strain" work (high demand/low control) was not associated with cancer risk compared with "low-strain" work (low demand/high control): multivariable HR 1.01 [95% confidence interval (CI), 0.94-1.08] for men and 0.99 (95% CI, 0.92-1.07) for women. Results were also null for most cancer types assessed: prostate, breast, colorectal, lung, and gastrointestinal (GI). The risk of GI cancer was lower for "passive" (low demand/low control) versus "low-strain" work, particularly for colorectal cancer in women: multivariable HR 0.71 (95% CI, 0.55-0.91), but statistical significance was lost after adjustment for multiple testing.Conclusions: The findings of this population-based, cohort study do not support a role for work-related stress in determining cancer risk.Impact: This study helps fill an important knowledge gap given the common concern about stress as a risk factor for cancer.

- Introduction: Impaired kidney function has been linked to both ischemic events as well as bleeding complications in several clinical conditions. Our aim was to investigate if cystatin C, creatinine and calculated glomerular filtration rate (eGFR) were related to future risk of bleeding complications, cardiovascular events or all-cause mortality during oral anticoagulant treatment.Materials and methods: In a cohort study, 719 patients on long-term vitamin K antagonist (VKA) treatment were followed for a mean of 4.2 years. Blood sampling was taken at inclusion and patients were followed prospectively. Cystatin C and creatinine were analysed and eGFR was calculated. All medical records were reviewed. Major bleeding events, myocardial infarctions, strokes, arterial emboli, and deaths were recorded and classified.Results: After adjustment for age, no association between cystatin C, creatinine or eGFR and major bleeding was found. Cystatin C was independently associated with cardiovascular events (hazard ratio 1.50 (95% CI: 1.27-1.77)) and all-cause mortality (hazard ratio 1.62 (95% CI: 1.38-1.90)). Creatinine was only associated with all-cause mortality, while eGFR was not associated with any of the outcomes.Conclusions: Our findings underscore the superiority of cystatin C as a marker of cardiovascular risk compared to creatinine or eGFR. VKA-treated patients with increased cystatin C levels should be considered to be at an increased risk of cardiovascular events, and not bleeding complications.

- Objectives: Previous studies have shown that biomarkers in blood plasma can predict bleeding complications during anticoagulant treatment as well as thromboembolic events and may improve existing risk stratification schemes in patients on or considered for oral anticoagulant treatment. The aim of this study was to investigate if levels of D-dimer, tissue plasminogen activator (tPA) and its complex with plasminogen inhibitor type 1 (tPA/PAI-1 complex) can predict major bleedings, cardiovascular events and all-cause mortality in patients with warfarin treatment.Design and methods: In a longitudinal cohort study, 719 patients on oral anticoagulant treatment were followed for a total of 3001 treatment years. Major bleeding, stroke, arterial emboli, myocardial infarction and death were recorded and classified. Blood samples collected at baseline were analyzed for D-dimer, tPA, and tPA/PAI-1 complex.Results: In multivariate Cox regression analysis, high levels of D-dimer were associated with major bleeding (HR 1.27 per SD; 95% CI: 1.01-1.60), cardiovascular events (HR 1.23 per SD; 95% CI: 1.05-1.45) and all-cause mortality (HR 1.25 per SD; 95% CI: 1.06-1.47). Neither tPA nor the tPA/PAI-1 complex was associated with major bleeding, cardiovascular events or all-cause mortality.Conclusion: We conclude that high levels of D-dimer predict major bleeding, cardiovascular events and all-cause mortality during warfarin treatment.
