Time in Nature Associated with Decreased Fatigue in UK Truck Drivers

Heavy goods vehicle (HGV) driving is recognised as a highly hazardous occupation due to the long periods of sedentary behaviour, low levels of physical activity and unhealthy food options when working. These risk factors combine with shift work and concomitant irregular sleep patterns to increase the prevalence of fatigue. Fatigue is closely linked with stress and, subsequently, poor physiological and psychological health. In parallel, a wealth of evidence has demonstrated the health and wellbeing benefits of spending time in nature. Here, we sought to examine whether spending time in nature was associated with lower levels of fatigue, anxiety and depression in HGV drivers. 89 long-distance drivers (98.9% male, mean ± SD age: 51.0 ± 9 years, body mass index: 29.8 ± 4.7 kg/m2) participating in a wider health promotion programme reported time spent in nature (during and before the Covid-19 pandemic) and symptoms of occupational fatigue, depression and anxiety. After controlling for covariates, truck drivers who visited nature at least once a week exhibited 16% less chronic fatigue prior to the pandemic, and 23% less chronic fatigue and 20% less acute fatigue during the pandemic. No significant differences were observed for either anxiety or depression. As fatigue has a range of physical and mental health sequelae, we propose that increased exposure to natural settings may make a valuable contribution to interventions to promote the health and wellbeing of this underserved group

Attenuated cardiovascular reactivity is related to higher anxiety and fatigue symptoms in truck drivers

Depression and anxiety have been linked with reduced stress-induced cardiovascular reactivity (CVR), which could be indicative of autonomic dysregulation. Less is known about the association between work-related fatigue and CVR. Truck drivers experience high levels of depression, anxiety, and fatigue, with repeated psychophysiological stressors on the road, yet little is known about the effects of these conditions on their CVR. 386 truck drivers completed the Hospital Anxiety and Depression Scale (HADS) and the Occupational Fatigue Exhaustion/Recovery Scale (OFER-15). Systolic (SBP) and diastolic (DBP) blood pressure, and heart rate (HR) were measured at rest and during a stressor protocol to measure CVR. Multivariate regression analyses were used to determine relationships between variables and adjusted for nine key covariates. Higher symptoms of persistent fatigue were related to a reduced SBP reactivity (β = -0.237, p = .008) and reduced DBP reactivity (β = -0.256, p = .005), whilst there was a positive trend between acute fatigue and DBP reactivity (β = 0.168, p = .053). Higher symptoms of anxiety were related to a reduced SBP reactivity (β = -0.167, p = .011). This study demonstrated in a population of truck drivers, both anxiety and persistent fatigue were related to an attenuated SBP reactivity in a combined model, whereas there was a positive trend between acute fatigue solely and DBP reactivity. These novel findings may have serious implications for cardiovascular disease risk in truck drivers, and future research should attempt to establish the causal effect of these associations and the underlying physiological mechanisms.</div

Attenuated cardiovascular reactivity to acute psychological stress predicts future fatigue symptoms in truck drivers

Objectives: This study aimed to investigate the impact of a 6-month health intervention on truck drivers’ CVR to stress and whether CVR was predictive of depression, anxiety, or fatigue symptoms at 6-months follow-up. Methods: 238 truck drivers completed a 6-month cluster RCT to increase physical activity and completed a stress protocol (Stroop and Mirror tracing tasks) with measurements of heart rate (HR), systolic (SBP), and diastolic (DBP) blood pressure taken, alongside fatigue, anxiety, and depressive symptoms assessment. Measures were taken at 0-months and 6-months. Results: Analyses showed a negative relationship between 0-month DBP reactivity and 6-month persistent fatigue. Trends towards negative relationships between SBP reactivity and future anxiety and fatigue symptoms at 6-months were evident. Conclusions: Our findings may have serious implications, as fatigue can be a major cause of road traffic collisions in truck drivers.</p

Sleep duration and sleep efficiency in UK long distance heavy goods vehicle drivers

Objective To profile sleep duration and sleep efficiency in UK long-distance heavy goods vehicle (HGV)drivers and explore demographic, occupational and lifestyle predictors of sleep. Methods Cross-sectional analyses were carried out on 329 HGV drivers (98.5% males) recruited across an international logistics company within the midland’s region, UK. Sleep duration and efficiency were assessed via wrist-worn accelerometry (GENEActiv) over 8-days. Proportions of drivers with short sleep duration (<6-h/24-h and <7-h/24-h) and inadequate sleep efficiency (<85%) were calculated. Demographic, occupational and lifestyle data were collected via questionnaire and device-based measures. Logistic regression assessed predictors of short sleep duration and inadequate sleep efficiency. Results 58% of drivers had a mean sleep duration of <6-h/24-h, 91% demonstrated <7-h sleep/24-h and 72% achieved <85% sleep efficiency. Sleeping <6-h/24-h was less likely in morning (odds ratio [OR] 0.45, 95% confidence interval [CI] 0.21–0.94) and afternoon (OR 0.24, CI 0.10– 0.60) shift workers (vs night) and if never smoked (vs current smokers) (OR 0.45, CI-0.22– 0.92). The likelihood of sleeping <7-h/24-h reduced with age (OR 0.92, CI 0.87–0.98). The likelihood of presenting inadequate sleep efficiency reduced with age (OR 0.96, CI 0.93–0.96) and overweight body mass index category (vs obese) (OR 0.47, CI 0.27–0.82). Conclusions The high prevalence of short sleep duration and insufficient sleep quality (efficiency) rate suggest many HGV drivers have increased risk of excessive daytime sleepiness, road traffic accidents and chronic disease. Future sleep research in UK HGV cohorts is warranted given the road safety and public health implications
