Abstract

Objectives: Most stress studies have used the questionnaire. Using salivary biomarkers to measure stress instead of questionnaire has several advantages. To study the association between salivary biomarkers (Salivary Cortisol and Salivary Immunoglobulin A), and the stress levels in police officers in Kuala Lumpur, Malaysia.

Methods: This was a cross-sectional study using cluster sampling to identify 2 district police headquarters in Kuala Lumpur in 2011. The study sample comprised of 497 subjects. The study with salivary cortisol and Salivary IgA comprised of 499 and 539 samples respectively. The Depression, Anxiety and Stress questionnaire was used as the research instrument. The Enzyme –linked Immunosorbent assay was used to measure the biomarker levels. The one way ANOVA and Non- Parametric test was used in the analysis.

Results: The prevalence of stress reported among police officers was 17.1% mild, 13.3% moderate and 5.9% severe to very severe stress. The analysis did not show any association between mean stress levels and mean salivary cortisol concentration nor between mean stress levels and mean salivary IgA secretion rates.

Conclusion: The absence of association may be related to the subjective nature of the questionnaire, the diurnal variations of the salivary cortisol and the single point sampling of the saliva for cortisol and IgA.
