Longitudinal associations between occupational stress and depressive symptoms

Job stress and chronic low back pain: incidence, number of episodes, and severity in a 4-year follow-up of the ELSA-Brasil Musculoskeletal cohort

ABSTRACT

We investigated the association between job stress, as assessed by the effort-reward imbalance model, and the incidence of chronic low back pain (CLBP) over a 4-year period. A total of 1733 participants from the ELSA-Brasil Musculoskeletal cohort, who were free from LBP at baseline (2012-2014), were included. Episodes of LBP in the past 30 days, intensity, and the presence of disability were investigated in annual telephone follow-ups (2015-2018). Chronic LBP was defined as episodes of LBP lasting >3 months with at least moderate intensity. We analyzed the incidence of at least one episode of CLBP (yes/no), the number of CLBP episodes (0, 1, ≥2), and CLBP severity/disability (absent, nondisabling, severe/disabling). The association between these outcomes and tertiles of the effort-to-reward ratio, as well as each dimension of the effort-reward imbalance model, was investigated using multinomial logistic and Poisson regression models adjusting for sociodemographic and occupational variables. The cumulative incidence of CLBP over 4 years was 24.8%. High effort-reward imbalance increased the chances of experiencing multiple CLBP episodes and severe/disabling CLBP by 67% (95% confidence interval [CI]: 1.12-2.47) and 70% (95% CI: 1.14-2.53), respectively. High overcommitment increased the incidence of CLBP by 23% (95% CI: 1.01-1.50) and the chances of multiple CLBP episodes and severe/disabling CLBP by 67% (95% CI: 1.11-2.50) and 57% (95% CI: 1.05-2.34), respectively. These results indicate that exposure to job stress is associated with a higher incidence, a greater number of episodes, and increased severity of CLBP over a 4-year period. If this association is causal, measures aimed at reducing exposure to job stress are likely to alleviate the burden of CLBP.

Association of nature of work and work-related characteristics with cognitive functioning, life satisfaction and depression among Indian ageing adults

BACKGROUND

Most individuals spend a significant amount of their time at work, and the dynamics at work can potentially influence their overall life, especially health and mental health. The present study tried to understand the association of the nature of work categorized as physically demanding, psychologically demanding, and environmentally hazardous on life satisfaction, cognitive functioning, and depressive symptoms among working middle-aged and older adults in India.

METHOD

We used data from the Longitudinal Ageing Study in India (LASI), Wave 1, collected between 2017 and 2018. The study sample consists of 28,653 working adults aged between 45 and 70. The study measures were assessed using standard tools. Linear regression analysis was employed.

RESULTS

The results indicate that individuals working in less physically demanding (β = 0.06, 99% CI = 0.02-0.09) and not hazardous environments (β = 0.15, 99% CI = 0.09-0.20) had better life satisfaction. Also, not being involved in hazardous work environments increased the likelihood of good cognitive functioning and reduced depressive symptoms (β= -0.17, 99% CI= -0.20- -0.15). However, samples involved in works requiring less psychological demand had an increased likelihood of reduced life satisfaction and increased depressive symptoms.

CONCLUSION

This study's results highlight the importance of creating a conducive working environment for the ageing adults.

Translation and Initial Validation of the Depression Anxiety and Stress Scale (DASS-21) in Ilokano

The Depression Anxiety and Stress Scale (DASS-21) is a self-report screening tool of psychological symptoms used in many countries and translated in different languages. The DASS-21 was translated into Ilokano, one of the major languages in the Philippines spoken by over 9 million people all over the world. The translation process involved independent translations by multilingual clinical psychologists, reviews by two multilingual mental health professionals, and pilot testing. The translation was then validated in a study with 668 Ilokano speakers mainly from three regions of the Philippines where Ilokano was a native language or a lingua franca. A confirmatory factor analysis indicated a good fit of the three-factor model compared to a one-factor model. The three subscales showed good internal consistency were also positively correlated with other measures of depression, anxiety, and negative affect, and negatively correlated with measures of positive affect and flourishing. Using a stringent test of criterion validity, the results also show that DASS-Depression was more strongly correlated with a criterion measure of depression, compared to with measures of anxiety and negative affect, and that DASS-Anxiety was more strongly correlated with a criterion measure of anxiety compare to a measure of negative affect. The results provide good initial evidence for the validity and viability of the DASS-21 in Ilokano, which should be a useful tool in mental health programs in parts of the Philippine community, particularly in identifying individuals who may need attention of mental health professionals.

Prevalence of current and former smoking in industrial workers worldwide: a systematic review and meta-analysis

OBJECTIVES

One of the health problems in recent decades is the prevalence of smoking in the world. In this study, the global prevalence of smoking in industrial workers was investigated using meta-analysis.

METHOD

The method of the present study was a systematic review and meta-analysis. Three scientific sources, PubMed, Web of Science, and Scopus, were selected for the search, and these databases were searched until September 2020. Random effects method was used for the analysis and then the analysis was performed for the type of smoking (Current, Former), gender, and continent. Heterogeneity was examined in all analyses.

RESULT

A total of 88 studies were included in the meta-analysis. The prevalence of smoking in industrial workers was 41% also the confidence interval was 35-48%. The prevalence of current smoking in industrial workers was 39% also the confidence interval was 29-48%. The prevalence of former smoking in industrial workers was 18% also the confidence interval was 13-22%. I² heterogeneity test was 99.9%.

DISCUSSION

From the findings of the present study, it can be seen that industrial workers are more exposed to smoking compared to the general population, and this can put their health at greater risk.
