Health and gender comparisons in the long-haul trucking industry: a pilot study

Cardiometabolic risk factors and mental health status among truck drivers: a systematic review

OBJECTIVE

This study aimed to systematically review and summarise the literature on cardiometabolic risk factors, lifestyle health behaviours and mental health status of truck drivers globally to ascertain the scale of these health concerns.

DESIGN

Systematic review reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

DATA SOURCES

PubMed, Scopus, PsycINFO and Web of Science were searched in January 2019 and updated in January 2020, from the date of inception to 16 January 2020.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Papers were included if they (1) reported independent data on truck drivers, (2) included quantitative data on outcomes related to cardiometabolic markers of health, mental health and/or health behaviours, (3) were written in English and (4) were published in a peer-reviewed journal. Grey literature was ineligible for this review.

DATA EXTRACTION AND SYNTHESIS

One reviewer independently extracted data and assessed methodological quality using a checklist based on the National Heart, Lung and Blood Institute Quality Assessment tool. 20% were independently assessed for eligibility and quality by a second reviewer. Due to heterogeneity of the outcomes, results were narratively presented.

RESULTS

3601 titles and abstracts were screened. Seventy-three studies met the inclusion criteria. Truck driving is associated with enforced sedentarism, long and irregular working hours, lack of healthy foods, social isolation and chronic time pressures. Strong evidence was observed for truck drivers to generally exhibit poor cardiometabolic risk profiles including overweight and obesity, hypertension, hypercholesterolaemia, high blood glucose, poor mental health and cigarette smoking.

CONCLUSIONS

Improving truck driver health is vital for the longevity of the trucking industry, and for the safety of all road users. The workplace plays a vital role in truck driver health; policies, regulations and procedures are required to address this health crisis.

The Impact of Work Organization, Job Stress, and Sleep on the Health Behaviors and Outcomes of U.S. Long-Haul Truck Drivers

Background. Compared with other occupations, long-haul truck drivers (LHTD) engage in excessively unhealthy behaviors and experience disproportionately poor health outcomes. Health promotion efforts targeting LHTDs focus on improving individual-level behaviors; however, this occupation is replete with adverse work organization characteristics, high job stress, and compromised sleep health, which are hypothesized to cause poor health behaviors and outcomes among LHTDs. Therefore, the purpose of this study was to explore the connections between work characteristics, job stress, and sleep outcomes, and health behaviors and physical and mental health outcomes among LHTDs. Method. This was a cross-sectional study, using interviewer-administered surveys with LHTDs (n = 260). Bivariate correlation analysis was used to explore the associations among work organization, job stress, sleep health, and health behaviors and outcomes. Logistic regression analyses were used to determine whether these work organization, job stress, and sleep factors predicted health behaviors and outcomes. Results. Long work hours of more than 11 hours daily (odds ratio [OR] = 2.34) resulted in increased odds of high caffeine consumption. High job stress (OR = 0.48) and poor sleep quality (OR = 0.42) led to decreased odds for spending at least 1 hour daily for cooking/eating. Low sleep duration, less than 7 hours daily (OR = 2.55), led to increased odds of a physical health diagnosis. Both high job stress (OR = 3.58) and poor sleep quality (OR = 2.22) resulted in increased odds of a mental health diagnosis. Conclusion. Health promotion efforts targeting LHTDs need to be coupled with upstream policy, environmental, and systems-level change, especially at the governmental and trucking industry levels.

Truckies and health promotion: using the ANGELO framework to understand the workplace’s role

Purpose

Workplaces are challenging environments which place workers at the risk of obesity. This is particularly true for Australian road transport industry workplaces. The Analysis Grid for Environments Linked to Obesity (ANGELO) framework is a public health tool which can be used to conceptualise obesogenic environments. It suggests that workplaces have a variety of roles (in the physical, economic, political and sociocultural domains) in responding to obesity in transport industry workplaces. The purpose of this paper is to present the findings which explore this idea.

Design/methodology/approach

The project used a mixed-methods approach located within a participatory action research framework, to engage workplace managers and truck drivers in the implementation and evaluation of workplace health promotion strategies. The project involved six transport industry workplaces in Queensland, Australia.

Findings

This study found that transport industry workplaces perceive themselves to have an important role in addressing the physical, economic, political and sociocultural aspects of obesity, as per the ANGELO framework. However, transport industry employees – specifically, truck drivers – do not perceive workplaces to have a major role in health; rather, they consider health to be an area of personal responsibility.

Practical implications

Balancing the competing perceptions of truck drivers and workplace managers about the workplace’s role in health promotion is an important consideration for future health promotion activities in this hard-to-reach, at-risk population.

Originality/value

The use of the ANGELO framework allows the conceptualisation of obesity in a novel workplace context.

Postural sway, working years and BMI in healthy truck drivers: an observational study

OBJECTIVES

The following study analyses the influence of risk factors among the occupational group of truck drivers on postural control and body mass index (BMI).

DESIGN

Observational study.

SETTING

One motorway station close to several highways in Germany.

PARTICIPANTS

180 truck drivers (177 male/3 female), aged 21-65 years old, took part in this study.

OUTCOME MEASURES

Postural control was examined using a pressure plate. In order to examine the influence of body weight (BMI) and working years on postural control, subjects were divided into samples of five and three groups, respectively. Furthermore, it was evaluated whether the subjects suffered from back pain. For data analysis, the Kruskal-Wallis test was used as the data were not normally distributed. Once the p value of the Kruskal-Wallis test was p≤0.05, the Conover-Iman comparison and afterwards the Bonferroni-Holm correction were used. The significance level was set at α ≤0.05.

RESULTS

Regarding the number of working years, a significant increase of frontal (p≤0.04) and sagittal (p≤0.001) sway were observed. The correlation of the five BMI groups with the number of working years demonstrates that an increase of the working years leads to an increase of BMI (p≤0.03). Furthermore, the majority of truck drivers participating in this study suffered from back pain (61.7%).

CONCLUSIONS

BMI and musculoskeletal impairment are indicators of health risk factors. In this study, it is shown that an increasing number of working years and an increasing BMI lead to a decrease in frontal and sagittal postural sway. In addition, the number of working years correlates with body weight and back pain.

Multiple Conditions Increase Preventable Crash Risks Among Truck Drivers in a Cohort Study

OBJECTIVE

This study aims to quantify the crash risk for truck drivers with multiple comorbid medical conditions, after adjusting for confounders.

METHODS

This retrospective cohort of 38,184 drivers evaluated concomitant medical conditions and subsequent crash data between January 1, 2005, and October 31, 2012. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were calculated for any cause and preventable crashes of varying severity.

RESULTS

Drivers with three or more medical conditions had a significantly increased risk of preventable Department of Transportation (DOT) reportable crashes (HR = 2.53, 95% CI = 1.65 to 3.88) and preventable crashes with injuries (HR = 2.23, 95% CI = 1.09 to 5.31) after adjustment for covariates. Similarly, adjusted HRs were 2.55 (95% CI = 1.37 to 4.73) for any cause DOT-reportable crashes and 3.21 (95% CI = 1.18 to 8.75) for any cause crashes with injuries.

CONCLUSIONS

Having three concomitant medical conditions may be a statistically significant risk factor for preventable and any cause DOT-reportable crashes and crashes with injuries.

A Pilot Study of Healthy Living Options at 16 Truck Stops Across the United States

PURPOSE

There is a growing body of evidence that the built environment influences diet and exercise and, as a consequence, community health status. Since long-haul truck drivers spend long periods of time at truck stops, it is important to know if this built environment includes resources that contribute to the emotional and physical well-being of drivers.

SETTING

The truck stop environment was defined as the truck stop itself, grocery stores, and medical clinics near the truck stop that could be accessed by a large truck or safely on foot.

DESIGN

Researchers at the National Institute for Occupational Safety and Health (NIOSH) developed and utilized a checklist to record the availability of resources for personal hygiene and comfort, communication and mental stimulation, health care, safety, physical activity, and nutrition at truck stops.

SUBJECTS

The NIOSH checklist was used to collect data at a convenience sample of 16 truck stops throughout the United States along both high-flow and low-flow truck traffic routes.

MEASURES

The checklist was completed by observation within and around the truck stops.

RESULTS

No truck stops offered exercise facilities, 94% lacked access to health care, 81% lacked a walking path, 50% lacked fresh fruit, and 37% lacked fresh vegetables in their restaurant or convenience store.

CONCLUSION

The NIOSH found that most truck stops did not provide an overall healthy living environment.

Occupational stressors and the mental health of truckers

Trucking has been classified as one of the highest-risk occupations in the United States. Occupational stress is even greater for long-haul truckers who are away from home, family, friends, and other support networks for several days or weeks at a time. Occupational stressors and the mental health of truckers was studied using data collected as part of a large multisite ethno-epidemiological study of trucker networks. Findings from the current study show that truckers face many occupational stressors including constant time pressures, social isolation, disrespectful treatment from others, driving hazards such as weather changes, traffic, and road conditions, and violence or fear of violence. Facing such stressors may be a factor in the prevalence of risky behaviors including drug use and paying for sex. Therefore, mental health promotion and treatment for truckers is an important area of concern and must be examined within the broader context of the transportation environment.

Worksite-induced morbidities among truck drivers in the United States

A critical review was conducted of social, psychological, and health science literature on the array of health risks and morbidities of truckers. Multilevel worksite-induced strains (e.g., long work hours and fatigue, shift work and sleep deprivation, postural fatigue and exposure to noise and vibration, sedentary lifestyle and unhealthy diet, exposure to diesel exhaust fumes, and other occupational stressors) were categorized into six primary morbidities for truckers: (1) psychological and psychiatric disorders; (2) detriments resulting from disrupted biological cycles; (3) musculoskeletal disorders; (4) cancer and respiratory morbidities; (5) cardiovascular disease; and (6) risk-laden substance use and sexual practices. Elevated morbidity risks suggest the need for the design and implementation of systematic epidemiological research and environmental interventions in the transport sector.

Hipertensão arterial e obesidade em motoristas profissionais de transporte de cargas

OBJETIVOS: Verificar a prevalência de hipertensão arterial e obesidade em motoristas profissionais de transporte de carga e associá-la com variáveis estudadas. MÉTODOS: Estudo transversal abragendo amostra de 258 motoristas profissionais de transporte de cargas que trafegavam pela Rodovia BR-116, no trecho paulista Regis Bittencourt. RESULTADOS: Os motoristas eram adultos jovens (37,5±10 anos), 19% tabagistas, 55% referiram ingestão de bebidas alcoólicas, 74% sedentários, 57% usavam medicamentos inibidores do sono, percorriam em média 800 km/dia e dirigiam 10 horas/dia. A prevalência da hipertensão arterial foi de 37%, 46% tinham sobrepeso, 36% obesidade e 58% circunferência abdominal aumentada. A análise de regressão logística indicou que a hipertensão arterial se associou (OD: Odds ratio, IC: intervalo de confiança a 95%) com: aumento do índice de massa corporal (OR=1,183 IC 1,065-1,314); glicemia (OR=1,039 IC 1,004-1,076); e hábito de ingerir medicamento para inibir o sono (OR= 0,322 IC 0,129-0,801). CONCLUSÃO: Foi expressiva a presença de hipertensão, sobrepeso e obesidade nesses profissionais.
