Job demands and DHEA-S levels: a study on healthcare workers

Background: The intricate interplay between work-related stress and its physiological impact has drawn extensive research attention. Dehydroepiandrosterone sulphate (DHEA-S) emerges as a potential biomarker reflecting stress-related endocrine changes.

Aims: This cross-sectional study aimed to examine the association between job demands and DHEA-S levels among healthcare workers. The study also explored potential correlations between DHEA-S levels and psychophysical symptoms commonly linked to work-related stress.

Methods: A sample of 488 healthcare workers from a local health authority participated. Job demands were measured using the Demands scale of the Health and Safety Management Standards Indicator Tool. DHEA-S levels and symptom prevalence were assessed through serum analysis and questionnaires, respectively.

Results: Workers exposed to high job demands exhibited significantly lower DHEA-S levels compared to those with low job demands. Psychophysical symptoms, including sleep disorders, depression, and headache, were more prevalent in the high-demands group. DHEA-S levels showed significant negative correlations with the prevalence of all considered symptoms.

Conclusions: The study shows the inverse relationship between job demands and DHEA-S levels among healthcare workers, indicating that high job demands correlate with reduced DHEA-S secretion and increased symptom prevalence. The findings suggest DHEA-S as a potential biomarker for assessing the physiological consequences of work-related stress. Proactive interventions in managing job demands are crucial for promoting employee well-being and productivity in demanding work environments. By recognizing DHEA-S as a stress biomarker, organizations can effectively address stress-related health risks and implement targeted interventions for enhancing employees' overall health and work performance.
