  • The level of leisure time physical activity is associated with work ability-a cross sectional and prospective study of health care workers
  • 2013
  • Ingår i: Bmc Public Health. - 1471-2458. ; 13:855
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: With increasing age, physical capacity decreases, while the need and time for recovery increases. At the same time, the demands of work usually do not change with age. In the near future, an aging and physically changing workforce risks reduced work ability. Therefore, the impact of different factors, such as physical activity, on work ability is of interest. Thus, the aim of this study was to evaluate the association between physical activity and work ability using both cross sectional and prospective analyses.METHODS: This study was based on an extensive questionnaire survey. The number of participants included in the analysis at baseline in 2004 was 2.783, of whom 2.597 were also included in the follow-up in 2006. The primary outcome measure was the Work Ability Index (WAI), and the level of physical activity was measured using a single-item question. In the cross-sectional analysis we calculated the level of physical activity and the prevalence of poor or moderate work ability as reported by the participants. In the prospective analysis we calculated different levels of physical activity and the prevalence of positive changes in WAI-category from baseline to follow-up. In both the cross sectional and the prospective analyses the prevalence ratio was calculated using Generalized Linear Models.RESULTS: The cross-sectional analysis showed that with an increased level of physical activity, the reporting of poor or moderate work ability decreased. In the prospective analysis, participants reporting a higher level of physical activity were more likely to have made an improvement in WAI from 2004 to 2006.CONCLUSIONS: The level of physical activity seems to be related to work ability. Assessment of physical activity may also be useful as a predictive tool, potentially making it possible to prevent poor work ability and improve future work ability. For employers, the main implications of this study are the importance of promoting and facilitating the employees' engagement in physical activity, and the importance of the employees' maintaining a physically active lifestyle.

  • The single-item measure of stress after myocardial infarction and its association with fatigue
  • 2015
  • Ingår i: Open Journal of Nursing. - 2162-5336 .- 2162-5344. ; 5:4, s. 345-353

    • Surviving a myocardial infarction (MI) can be a stressful event entailing challenges in daily life during the recovery period. Experiencing fatigue symptoms post-MI has been described as bothersome and occurs in nearly half of patients four months and two years after MI. The aetiology of fatigue disorder is unclear, but research has shown that fatigue plays an important role in the relationship between stress and perceived poor health. Previous findings indicate that having access to an easily administered stress measurement is worthwhile both in the clinic and in research. The single-item measure of stress symptoms has not been validated in persons treated for MI. The aim was to validate the single-item measure of stress symptoms and to explore its association with fatigue in a sample of persons treated for MI. Methods: 142 respondents completed the questionnaires of the Multidimensional Fatigue Inventory-20, the single-item measure of stress symptoms and the Perceived Stress Scale-10 (PPS-10) two months post-MI. Correlation analysis and t-tests were used to validate the single-item stress measure and its association with post-MI fatigue. Results: The convergent validity of the single-item measure of stress symptoms was confirmed. In analyses of relations between stress and fatigue, it was found that the single-item stress measure was strongly associated with both the global fatigue score and all four fatigue dimension scores (general, physical and mental fatigue as well as reduced activity). Conclusion: The single-item measure of stress symptoms was found to be a valid measure of post-MI stress. Also, the measure was useful in assessing associations between stress and fatigue and could therefore indicate that post-MI fatigue experiences should be further explored in full using multidimensional fatigue assessmen

  • Cardiorespiratory fitness protects against stress-related symptoms of burnout and depression
  • 2013
  • Ingår i: Patient Education and Counceling. ; 93:1, s. 146-152
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To examine how cardiorespiratory fitness and self-perceived stress are associated with burnout and depression. To determine if any relationship between stress and burnout/depression is mitigated among participants with high fitness levels.METHODS: 197 participants (51% men, mean age=39.2 years) took part in the study. The Åstrand bicycle test was used to assess cardorespiratory fitness. Burnout was measured with the Shirom-Melamed Burnout Questionnaire (SMBQ), depressive symptoms with the Hospital Anxiety and Depression Scale (HAD-D). A gender-matched stratified sample was used to ensure that participants with varying stress levels were equally represented.RESULTS: Participants with moderate and high fitness reported fewer symptoms of burnout and depression than participants with low fitness. Individuals with high stress who also had moderate or high fitness levels reported lower scores on the SMBQ Tension subscale and the HAD-D than individuals with high stress, but low fitness levels.CONCLUSION: Better cardiovascular fitness seems to be associated with decreased symptoms of burnout and a better capacity to cope with stress.PRACTICAL IMPLICATIONS: Promoting and measuring cardiorespiratory fitness can motivate employees to adopt a more physically active lifestyle and thus strengthen their ability to cope with stress exposure and stress-related disorders.

  • Fitness Moderates the Relationship between Stress and Cardiovascular Risk Factors
  • 2016
  • Ingår i: Medicine and Science in Sports and Exercise. - 0195-9131. ; 48:11, s. 2075-2081
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose This cross-sectional observational study examined the degree to which cardiorespiratory fitness (CRF) and self-perceived stress are associated with cardiometabolic risk factors and the overall risk score for cardiovascular diseases. The second aim was to determine whether participants' CRF levels moderate the relationships between stress and cardiometabolic risk. Methods A gender-matched stratified sample (N = 197, 51% men, M-age = 39.2 yr) was used to ensure that participants with varying stress levels were equally represented. CRF was assessed with the angstrom strand bicycle test, and perceived stress was assessed with a single-item question. Systolic blood pressure (SBP) and diastolic blood pressure (DBP), body mass index (BMI), total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), glycated hemoglobin, and total cardiometabolic risk score (sum of the z-standardized residuals of the previously mentioned indicators) were assessed as outcomes. Results Higher LDL-C, TG, and total metabolic risk were found in participants with high stress scores (P < 0.05). In addition, lower SBP, DBP, BMI, LDL-C, TG, and total metabolic risk were observed in participants with high CRF (P < 0.05). Two-way ANCOVA provided significant interaction effects for five of the nine outcome variables (P < 0.05, 3.6%-4.8% of explained variance). Participants with high stress who also had high CRF levels had lower SBP, DBP, LDL-C, TG, and total cardiometabolic risk than participants with high stress but low or moderate CRF levels. No significant main or interaction effects occurred for BMI, total cholesterol, high-density lipoprotein cholesterol, and glycated hemoglobin. Conclusion Better CRF is associated with more favorable levels of several cardiometabolic risk factors, specifically in participants experiencing high stress. Higher CRF may provide some protection against the health hazards of high chronic stress by attenuating the stress-related increase in cardiovascular risk factors.
