Attenuated Cardiovascular Reactivity to Acute Psychological Stress Predicts Future Fatigue Symptoms in Truck Drivers

This article reports on a study that evaluated the impact of a 6-month health intervention on truck drivers' cardiovascular reactivity to stress. The study also considered whether cardiovascular reactivity was a predictor of depression, anxiety, or fatigue symptoms at 6-month follow-up. The authors used a cluster randomized, controlled trial in 238 truck drivers, who each completed a stress protocol (Stroop and mirror-tracing tasks) with measurements of heart rate, systolic blood pressure, and diastolic blood pressure. The truck drivers also underwent an assessment of fatigue, anxiety, and depressive symptoms. Similar measurements were taken at baseline and at 6 months. Half of the cohort was randomized into the multicomponent health intervention group, which included a health workshop, use of a FitbitĀ® Charge 2 (Fitbit, Inc., San Francisco, CA), fitness equipment, and ongoing health coach support via text messages. The study found no intervention effects; there were no differences between the two groups at any time point for measures of fatigue, anxiety, or depression. The authors found a negative relationship between baseline diastolic blood pressure reactivity and 6-month persistent fatigue. In addition, trends toward negative relationships between systolic blood pressure reactivity and future anxiety and fatigue symptoms at 6 months were found. The authors conclude with a brief discussion of the implications of their findings, particularly in light of the role of fatigue as a cause of motor vehicle crashes in truck drivers.
