Work-Related Psychological Injury Is Associated with Metabolic Syndrome Components in Apparently Healthy Workers

Objective

The aim of this study was to evaluate the association between psychological damage caused by common occupational trauma and metabolic syndrome (MES).

Method

571 workers from 20 small Italian companies were invited to fill in the Psychological Injury Risk Indicator (PIRI) during their routine medical examination at the workplace.

Results

Compared to workers with no psychological injury, workers with a high PIRI score had a significantly increased risk of having at least one metabolic syndrome component (adjusted hazards ratio, 1.8; 95% confidence interval, 1.2 to 2.6). There was a significant increase in the risk of hypertriglyceridemia in male workers (OR 2.53 CI95% 1.03-6.22), and of hypertension in female workers (OR 2.45 CI95% 1.29-4.66).

Conclusion

Psychological injury related to common occupational trauma may be a modifiable risk factor for metabolic syndrome.
