Risk Factors for Chronic Non-communicable Diseases of Long-Haul Truck Drivers: Integrative Review

1. Introduction

The main risk factors for the development of Chronic Noncommunicable Diseases (NCD) are linked to behaviors and the environment and include sedentary lifestyle, poor diet, smoking, alcohol consumption and chronic stress. These contribute to the epidemic increase of hypertension, diabetes mellitus, obesity, smoking, anxiety, depression and post-traumatic stress disorder; in recent years, because of the SARS-Cov2 pandemic (COVID-19), this global NCD syndrome has been aggravated [1].

Although preventable and/or modifiable, NCDs affect two billion people, causing three quarters of the deaths worldwide which corresponds to the death of 28 people every minute, due to some NCDs [2]. The World Health Organization (WHO) and the International Labour Organization (ILO) recognize that the high rate of NCDs contributes to the increase in mortality and loss of years due to disability DALYs (Disability Adjusted Life Years), causes damage to health systems, social security and economy of countries [2,3].

The road transport sector moves the world economy. Without the road transport sector, and long-haul truck drivers in particular, food, supplies, medications and various other essential products would never reach their destinations. Several studies have shown that the everyday work of long-haul truck drivers (LHTD) involve a series of occupational stressors including long journeys (more than 11 hours daily), irregular working hours, pressure related to schedules, chronic stress, social isolation, absence of routine regular physical activity and high risk of chronic non-communicable diseases (NCD) [4,5,6]. Long working hours (> 55 hours a week) are considered the largest occupational risk factor, to which 8.9% of the world’s population is exposed [7]. The work organization of the road transport sector can negatively influence the physical, cognitive and emotional health of workers, causing an imbalance in the work-life relationship [8].

It is important to explore the literature for the biological, behavioral, environmental and/or occupational risk factors that influence well-being and that contribute to the development of chronic non-communicable diseases in LHTD. In addition, articulating recommendations to promote the physical, cognitive and emotional health of LHTD, to overcome the challenges to achieve the goals of the Global Action Plan for the Prevention and Control of Chronic Non-Communicable Diseases 2023-2030 [2], as well as, the objectives of the UN Agenda 2030 for Sustainable Development [9], and presenting gaps in knowledge are also important. Given this context, the following guiding question of this study was formulated: What do we know about biological, behavioral and environmental risk factors for the development of chronic non-communicable diseases in long-haul truck drivers? This study aimed to analyze and synthesize the scientific findings about risk factors for the development of chronic non-communicable diseases in LHTD.

2. Materials and Methods

This is an integrative systematic review of the literature on biological, behavioral and environmental risk factors for the development of chronic non-communicable diseases and provides recommendations to promote the physical, cognitive and emotional health of LHTDs. Our aim is to help improve the practice of nurses in the health care of LHTDs, after the largest public health emergency of the last century -- the COVID-19 pandemic. To do so, seven steps were followed: (1) Write the review question, (2) Determine the search strategy, (3) Critical appraisal of the search results, (4) Summarise the search results (5) Data extraction and reduction, (6) Analysis, and (7) Conclusions and implications [10].

The problem was identified, that is, the occurrence of chronic non-communicable diseases in LHTDs, and the review question was established: “what scientific evidence are available in the literature about biological, behavioral and environmental risk factors for the development of chronic non-communicable diseases in long-haul truck drivers and the pandemic? The approach was based on the PICo strategy (P – Population, represented by long-haul truck drivers; I – Interest, expressed by the work-life-prevention relationship of chronic non-communicable diseases; Co – Context, Global – and the COVID-19 pandemic) [11].

The selection and review of studies took place from June to December 2023, from data collection and critical evaluation of the studies. The search strategies were performed from the descriptors in Health Sciences (DECs) and the respective terms of the SBJECT Headings Medical (Mesh) with the Bolean operator “and” “Long-Haul Truck Drivers”; “COVID-19”; “Health”; “Work-Life Balance”. The databases used were the National Library of Medicine (Medline) by the Virtual Health Library (VHL), with the following intersections. On the VHL regional portal (Long-Haul Truck Driver) = 13 (Long-Haul Truck Driver) and (Work-Life Balance) = 00 (Long-Haul Truck Driver) and (Health) = 02 (Long-Haul Truck Driver) And (COVID-19) = 01 (Long-Haul Truck Driver) and (Work-Life Balance) and (COVID -19) = 00. PubMed (Long-Haul Truck Driver) = 19 and (Work-Life Balance) = 00 (Long-Haul Truck Driver) and (Health) = 00 (Long-Haul Truck Driver) and (COVID -19) = 03.

The inclusion criteria were primary human studies, with either qualitative or quantitative methodologies (or both), randomized clinical trials, prospective and retrospective cohort studies, case control studies, cross-sectional studies, and published in Portuguese, English or Spanish between 2018 to 2022. The time frame adopted in the selection of articles was adopted to obtain studies published in the last five years, during the COVID-19 pandemic, studies available in full in English, Spanish or Portuguese, and that answered the research question. Dissertations, thesis, books, book chapters, editorials, newspaper articles, literature reviews, letters to the editor, reflective studies, experience reports and studies that did not respond to the objective of the review were excluded.

The selection of the studies occurred in the Rayyan application [12] and was conducted by two reviewers and a third was consulted when questions arose. A data collection instrument was developed by the researchers, addressing the following information: Authors, year and country of publication, objective, design, main results and recommendations for the prevention of chronic non-communicable diseases. Duplicate articles, which were articles that appeared in more than one database were grouped based on the database that contained a larger number of studies. This organization enabled the detailed visualization of the information for further analysis. After the search strategies were applied, 38 studies were found (Figure 1). All titles and abstracts were read to determine if the studies met inclusion criteria, which resulted -- 14 (of 38) studies that were excluded because they did not answer our research question and or because they were duplicates. When the abstract did not clearly determine whether the article should or should not be included, the article was read in full to determine its eligibility. For the critical appraisal of the search results, twenty-three articles were submitted to a full reading, and found to have met our inclusion criteria, thus all 23 were included in this review. For a summary of the search results, the guidelines of the Guidelines of Preferred Items of Systematic Reviews and Meta-Analyses (PRISMA) [13] were followed.

For data extraction and reduction of the selected articles, a researcher-developed instrument containing the following items was used: authorship; year of publication; objectives of the study; methodological description; characteristics of the sample; results and conclusions.

A descriptive analysis of the data was carried out from the reading of the titles and abstracts, as well as the full reading of the selected articles. The thorough reading allowed the convergent synthesis of the themes found in the literature. To calculate the means of prevalence of diagnoses of hypertension, diabetes mellitus, cholesterol, physical activity, sedentary lifestyle, obesity, smoking habit and alcohol consumption, a simple arithmetic mean calculation of the results presented in the review studies, highlighting the minimum and maximum value were performed. For the classification of biological, behavioral and environmental domains in the presentation of risk factors for chronic diseases (Table 2) and general recommendations to promote the physical, cognitive and emotional health (Table 3), the Global Action Plan for the Prevention and Control of NCDs 2023-2030 [2] document was used. And the International Labour Organization’s advancing the global agenda on prevention and control of noncommunicable diseases 2000 to 2020: looking toward 2030 [3] was also used. The biological risk factors inherent to the individual, considered non-modifiable, were age, sex, and gender. race and chronic diseases. The behavioral and environmental risk factors, considered modifiable, were described as education level, physical activity, smoking habit, overweight/obesity, inadequate diet, alcohol consumption, socioeconomic conditions, occupational safety, stress, depression, anxiety, fatigue, hours of sleep, number of hours and days of work in the week and month, time out of home, ergonomic risk, and access to health services. From this analysis it was possible to construct the conclusion and implications based on two categories, called “biological, behavioral and environmental risk factors for the development of chronic non-communicable diseases in long-haul truck drivers” and “general recommendations to promote the physical, cognitive and emotional health”.

3. Results

From the strategies employed in the search and recovery, 38 studies were identified, 23 in the Pubmed database and 16 in Medline (Figure 1).

After reading the titles and abstracts, 23 articles were selected for full reading [13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35] (Table 1).

The studies were conducted on five continents and in 10 countries, South Africa [25,32,35], Germany [22], Australia [26,36], Brazil [21], Canada [27,30], Spain [34], United States [14,15,17,19,23,24,28,29,31,33], Finland [20], Iran [16], and Sweden [18]. In 2018, eight articles were published [14,15,16,17,18,19,20,21]; followed by six publications in 2019 [22,23,24,25,26,27], two in 2020 [28,29], five in 2021 [30,31,32,33,34], and two publications in 2022 [35,36].

The 23 studies analyzed aimed to evaluate sleep [19,20,21], sleep and mental health [23,24,29], sleep and risk of cardiovascular disease [32], Diet [22], diet and physical activity [26], risk of cardiometabolic disease [17,18]. The prevalence of obesity and its association with systemic arterial hypertension and diabetes mellitus [35], sexual health [14], and sexually transmitted infection (STI) [33], risk of musculoskeletal injury [15], fatigue and occupational safety [34], physical and mental health [25,36], smoking [28], symptoms of depression [26] and about the health of truck drivers in the early years of the COVID-19 pandemic [30].

The authors evaluated the health of 7,363 LHTDs -- the samples ranged from 13 to 1,390 participants, with an average of 328 participants [14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36]. Of these, the methodology used in 19 studies was described as quantitative observational [14,15,17,19,21,22,23,24,25,26,27,28,29,31,32,33,34,35,36], a qualitative study [18], a case-control study [16] and an intervention study in education [20] (Table 1). None used mixed or multiple methods.

From the analysis of the 23 articles, biological, behavioral and environmental risk factors that contribute to the development of chronic non-communicable diseases in LHTDs were identified (Table 2). The average prevalence of diagnoses of hypertension was 24.6%, Diabetes Mellitus (11.6%), High Cholesterol (27.2%), Practice of Physical Activity (38%), Sedentarism (38.8%), BMI> 25 (55.3%), Obesity (48.4%), Smoking habit (37.1%), Alcohol consumption (48.5%).

The general recommendations to promote the physical, cognitive and emotional health were presented based on the themes addressed in the studies and described following the recommendations of the studies, the WHO’s global goals for the prevention of NCD [2]. and advancing the global agenda on prevention and control of noncommunicable diseases 2000 to 2020: looking forwards to 2030 [3] as a way to promote the health of LHTDs were described in (Table 3).

4. Discussion

When analyzing the articles regarding the evaluation of the occurrence of chronic non-communicable diseases and the recommendations of studies for the promotion of health of LHTDs, the results was presented in two categories: 1) biological, behavioral and environmental risks, and 2) general recommendations to promote physical, cognitive and emotional health.

4.1. Biological, Behavioral and Environmental Risk Factors for the Development of Chronic Non-Communicable Diseases in Long-Haul Truck Drivers

From the evaluation of the studies it was possible to identify biological, behavioral and environmental risk factors for the development of chronic non-communicable diseases in LHTDs. Among the biological factors, not modifiable for the development of chronic non-communicable diseases, the studies presented data on age, race, genetics and diagnosis of chronic diseases. Regarding age, 55% and 60% of the studies showed that LHTDs were over 45 years old [17,36]; other studies, with an average of more than 46 years old [19,30,35]; 50 years [24,27], and 53 years old [14,15,21,22]. Male sex is the most affected by premature deaths due to chronic non-communicable diseases and in all studies analyzed there was a predominance of male participants [14,15,17,18,21,22,25,27,28,30,31,32,34,36]. Only one study had a predominately female sample [29]. African Americans presented a higher risk for developing diabetes mellitus, although the sample in the articles were predominately Caucasian participants [14,15,19,27,29]. The study developed in South Africa had a predominance of African people in their sample [32].

Some chronic diseases have an important genetic component for health, such as hypertension, diabetes mellitus and obesity. The description of risk of diseases related to genetic factors was pointed out by one study, a professional, who reported that the cause of death of the father was due to heart attack, 3% of the participants revealed that their parents had stroke before the age of 60 [25], and 5% with history of acute myocardial infarction [14]. In other studies, the description of the diagnosis of some chronic non-communicable disease was frequent in 51% of LHTDs, with at least one chronic disease and there was a higher prevalence for arterial hypertension (33%) and high cholesterol (28%) among participants [23], 39.8% had high blood pressure diagnosis, 45.8% high cholesterol and 14% with diabetes mellitus [14], 71% of those who were overweight had some chronic disease (hypertension, diabetes and or chronic back pain) [22,30] and 30% reported three or more chronic health conditions [36]. For the diagnosis of hypertension, a mean of 22.5% was identified, with a minimum of 11% [25] and a maximum of 34% of hypertensive drivers [36]. Diabetes mellitus was identified on average in 14.5% of drivers, ranging from 2% [25] to 27% [17], and a mean of 27.2%, the diagnosis of high cholesterol varied from 7.8% [36] and 45% [14] of the participants of the studies.

Education level is a determining factor in people’s health due to increased exposure to risk factors and limitations to access to information and health services. The predominant level of education among drivers was high school in 91% [22]; followed by 56% who studied between four and eight years [21], 26% completed high school and more than 20% had studied at the college [30].

Sedentary behavior is related to the development of chronic diseases, and the evaluation of physical activity showed that on average 30.5% practiced physical activity three hours a week or more [31], with variation from 1% to 60% [23]. Similarly, the average of sedentary drivers was 48.5%, ranging from 26% to 45% [32,35].

Proper and healthy eating is a basic human right, promotes health and is related to the lower risk of chronic diseases. Regarding the diet of LHTDs, 74.2% reported spending only a few minutes to an hour per day for cooking and eating [23], 73% reported eating food brought from home and 32% reported eating the main meal in the places of stopping and resting [22], 88% consumed less vegetables than recommended, 63% consumed at least one health-damaging food per day and 65% consumed one can of sugary drink per day [26]. In addition, the difficulty of finding restaurants that were open during the COVID-19 pandemic was reported by 82% of drivers [30].

The control of overweight and obesity is considered fundamental for reducing the prevalence of chronic diseases. Among the studies evaluated, overweight was identified in studies that considered BMI > 25, the mean was 55.3%, with a minimum variation of 25.2% [32,36] and 90% [26] and obesity, on average 48.4%, ranging from 28% [22,32,35], to 69% [25]. Significant correlation was identified among drivers who ate meals in restaurants with weight gain during COVID-19 [30].

Among the modifiable behavioral risk factors for NCD illness, studies showed that tobacco consumption by LHTDs was on average 37.1%, with variation between 1.8% [21] and 68% [28]. Among smokers, 48.8% made at least one attempt to quit smoking the previous year [14]. The use of alcohol on days off work for 48% [23], and 50% reported consumption in the last 30 days [14]. Other studies have shown that the average usual consumption was 48.5%, with variation between 39% [21] and 57% [35]. Alcohol consumption by drivers compromises safety, and as well as tobacco use, increases the risk of chronic diseases and requires change in behavior, and prevention and control policies to reduce the consumption and marketing of cigarettes and alcohol harmful to health.

Income is part of the socioeconomic conditions, which define the living and working conditions of people. In the evaluation of drivers’ income, 54% earned more than $80 thousand US dollars per year and 95% of their revenue going to truck maintenance and labor-related expenses [14].

Increased stress at work may increase depression rate among drivers (HATAMI et al., 218). In a study of anxiety, depression, sleep and fatigue, there was a positive association between work and depression; drivers without co-pilots presented moderate to severe depression, while those with co-pilots had lower rates of depression, compared to those who worked alone [16]; 7% with anxiety and 12% with depression [19], 40% moderate perceived stress [24]; 8% Depression, 4% Posttraumatic Stress Disorder and 18% Daytime Drowsiness [25]; 19.4% of mental health problems [36]; 9% with severe headache and 10% with chronic fatigue, 60% moderate to chronic stress [23], 62% moderate or high perceived stress [24], 10% reported symptoms of anxiety or loneliness [29]. Drivers who reported depressive symptoms had a higher chance of low back pain, fatigue, fewer hours of sleep per night and greater use of medications [27] and 85% of drivers with depressive symptoms did not maintain follow-up appointments with their health care providers [27].

Time spent at work can be a barrier to changing behavior and adopting healthy habits. In the evaluation of the number of working days per week and month were described as more than five days per week in 73% [34], more than 15 days per month, by 85% [22,24]; and average of 20 days/month [25], more than 25 days per month, in 84% of participants [24]. As for working hours per day, the classification was five to eight hours per day was 11% and 53 % [34,36], 30% worked more than eight hours per day [21], more than 10 hours 53% [32]; mean of 10 hours per day [25], more than 11 hours per day was reported by 32% [24] and 50.4% [36], and more than 13 hours per day by 37.5% [36] and 38% [24]. It is understood that during the COVID-19 pandemic the workday for drivers has increased, considering that drivers carried essential items such as food and medical-hospital materials, which led 58% of drivers to report loss in quality of life from the outset of the COVID-19 pandemic [30].

Sleep hygiene is essential for the prevention of chronic diseases such as hypertension, diabetes mellitus, obesity, depression and road accidents, however, 29% of long-haul truck drivers reported worsening sleep quality during the COVID-19 pandemic [30]. Sleeping fewer than six hours compromises health, but sleep duration is a modifiable risk factor and in the evaluation of the number of hours of sleep was on average less than seven hours for 46% of drivers [23], seven hours of sleep [19] and more than seven hours of sleep [21,29,32]. The amount of time out of the house (i.e., on the road, working) and the feeling of loneliness varied according to the relationship with the company, the independent truck drivers stayed out of the house for significantly more nights than the company’s truck drivers [14] and 76% reported frequent support from supervisors [24]. In general, the period far from home varied in more than 21 days to 84% [24], and more than 14 days to 33% [22].

The driver’s work involves ongoing monotonous activity for hours and this can compromise safety. In order to maintain social interaction and decrease boredom, drivers performed secondary tasks while driving [18] and reported that they maintain social interaction and communication with friends, colleagues by smartphone and virtual social networks, and in places of stopping and rest [18].

The working conditions of drivers can cause acute musculoskeletal injuries that can then become chronic. The risk assessment of musculoskeletal injury showed that for 53% of drivers the injuries have led to the removal of work in the last 12 months [15]. Of these, 30% was the result of a drop in the same level and 32% by contact with object or equipment and 15% by effort [15]. The injuries occurred on the arm, shoulder and hand, for 26% of drivers and in 21% went after the neck and back, and 15% in the legs [15]. In other studies, 27% work-related injury and 26% reported chronic back pain [22]; 10% had work-related pain that lasted more than three months [25], and 40% chronic pain lasting three to 12 months [36], demonstrating the potential for chronicity.

The difficulty in accessing health services by LHTDs compromises the prevention of chronic non-communicable diseases. In an evaluation of health monitoring by professionals, 32% reported monitoring annually or every two years to 62.8%; 32% of truck drivers reported conflicts between work schedules and hours of care in health services and 19.6% citing financial problems that prevented them from obtaining health care [14]; 85% of drivers who reported depressive symptoms and who did not receive any form of psychiatric medications and 80% did not receive professional mental health treatment [27].

4.2. General Recommendations to Promote Physical, Cognitive and Emotional Health in Long-Haul Truck Drivers

The general recommendations of the studies to promote the physical, cognitive and emotional health were presented as a way to promote the health of LHTDs and were described in the (Table 3). These were categorized into behavioral and environmental areas (modifiable). In the behavioral area, the recommendations from this review about the promotion of physical activity were presented to increase the opportunities of physical activity with the installation of gyms in the places of stop and rest, availability of hiking trails and physical activity with supervision of health professionals, as well as providing health education on the importance of physical activity [14,17,23,31,32].

As for healthy eating, the need to provide health education for changing behavior was highlighted, increase the opportunities for healthy diet, with the availability of nutritious foods with fruits, vegetables, nutritious meals and free of excess salt, saturated fats, trans and sugars [14,17,22], as well as the recommendation for the automotive industry to improve food preparation sites in trucks [22]. Considering that 56% reported that finding a place to park is always a problem and for 64% was even higher during the COVID-19 pandemic [30].

The promotion of sleep and rest health was addressed in recommendations on the importance of encouraging rest and sleep hours [17,19,27,32], highlighting the importance of ensuring that the place of sleep is quiet, with adequate temperature control, and with quality air [17]. Also, to provide health education on the importance of sleep quality [27]; to monitor, detect and offer information on sleep changes and association with the risk of cardiovascular diseases [19], use new technologies to enable personalized, intensive and relevant training [20,32] and use strategies such as physical exercise, avoiding caffeine or other stimulants before bedtime [17], as well as providing resources and incentives to manage weight and reduce the risk of sleep disorders [17] and implement sleep disorder screening and treatment programs [17]. Still in relation to sleep quality, a study showed that monitoring the use of drugs, 53% of drivers who used antihypertensive drugs reported good or optimal sleep quality [21].

In addition, there is a need for initiatives to prevent STI with interventions to evaluate behavior, health education to prevent and control risk of infection by STI/HIV [32,33]. Health education interventions for smoking prevention and control [14], as well as text message interventions three times a week and counseling 10 to 15 minutes [28]. Similarly, the recommendations for health education interventions were recommended for prevention and control of the use of psychoactive/narcotic substances/drugs/alcohol [27]. With indication of mental health professional attendance via telephone, 24 hours (tele-health), or in online support groups, availability of emotional support and stress management technique [24,27,29], occupational stress level assessment [17]. In addition, one can explore the viability, acceptability and effectiveness of mindfulness practice. To encourage the practice of Mindfulness, considering that the practice of mindfulness acted as a protector against post-traumatic stress disorder [29].

In the environmental area, recommendations involving the work environment were included. These were described as general recommendations and highlighted the importance of expanding the opportunities for stopping and rest [14,23,34], with availability of space for basic needs and meals with tables and chairs [14,22].

For the prevention of injuries, it is recommended to evaluate and control risk factors and mechanism of injuries, use evidence to develop prevention and intervention protocols in work-related injuries [15]. The reorganization of the working day was pointed out as urgent, considering that more than 80% reported having a different daily work schedule each day [24] and the reorganization of working hours can act in the prevention of strenuous working hours [34], considering that professionals who had extensive journeys, had four times more chances of depression [27]. On the other hand, drivers with co-pilot had lower stress and depression rate [16].

There was an urgent recommendation to promote access to health care services for the prevention of non-communicable diseases, control of hypertension, diabetes mellitus and obesity, as well as the medications necessary to control non-communicable diseases. Health care services could be face-to-face at health centers close to roadways or online, need to include detecting and reporting on sleep, and disorders and their association with the risk of metabolic and cardiovascular diseases [14,27,31,32].

No studies were found that addressed two important issues for the prevention of chronic diseases. The first gap is knowledge about the social support network in and outside the workplace. Improving opportunities for social interaction in places of rest and rest with spaces for sports activities and intellectual games could have the potential to improve physical, cognitive and emotional health. Social interaction improves one’s sense of belonging, favors resilience, increases concentration, reduces loneliness and stress. The second gap is the absence of studies addressing opportunities for personal growth, learning spaces, such as libraries, face-to-face or online training, that promote the development of skills and individual growth in the workplace, in places of rest or remotely. Encouraging self-development, continuing education, skills development and participation in training can contribute to improving cognitive and emotional health. In addition, these activities can improve memory, performance at work, problem solving, concentration, interpretation and health literacy; and promote informed decision-making in health for the prevention and control of chronic non-communicable diseases.

4.3. Limitations

The possible limitations of the study may be related to the scarcity of studies produced during the COVID-19 pandemic period, which did not allow the deepening of how risk factors changed or were accentuated due to the need for care to prevent contagion. In addition, the methodological strategy adopted may have influenced the result, since it is estimated that the increase of search time and the inclusion of other databases and other languages could have expanded the sample. However, it is considered that this does not decrease the quality of the study, considering that appropriate methodological strategies were adopted to obtain the best scientific evidence, developed by researchers recognized in their areas and published in scientific journals with high impact indexes.

4.4. Contributions to Practice and Future Studies:

The Evidence Raised in This Study Can Contribute to Improve the Approach of Professionals to the Health of Truck Drivers, in the Prevention of Chronic Diseases, as Well as to Promote Reflection on the Need for Urgent Changes in Legislation and Work Organization, as Well as in the Environment of Places of Rest So that Measures Aimed at the Prevention of Chronic Non-Communicable Diseases Are Implemented. In Addition, the Gaps Found in the Scientific Literature on the Absence of Studies Addressing the Influence of the Social Support Network and the Encouragement of Personal Growth in Health Promotion and Encouraging the Development of other Studies that Promote Advances in the Prevention and Control of Chronic Non-Communicable Diseases Were Present in This Population.

5. Conclusions

The results of the study reported a synthesis of the evidence about the risk factors for the development of chronic non-communicable diseases in LHTDs and described recommendations for the promotion of physical health, cognitive and emotional of LHTD. Based on the analysis of the studies included in this review, it is clear that macrostructural changes are needed, which may improve working conditions, from the work and rest environment of LHTDs, and reduce barriers and allow behavioral changes such as access to health services, medications for control and treatment of NCDs, health education, implementation of programs to encourage physical activity, healthy eating, reduction of sedentary behavior, obesity, stress and depression.

The general recommendations of the studies to promote the physical, cognitive and emotional health were categorized in the behavioral and environmental areas, which are modifiable, such as the promotion of physical activity practice, healthy eating, health education on the quality and importance of sleep hours, control of tobacco and drug use, STI, and work reorganization, considering that long journeys are considered the highest occupational risk for heart disease, stroke, and deaths. For this, the demand to promote an environment conducive to changing behavior needs to be part of the global NCDs prevention agendas.

This study presented as a contribution the description of the main risk factors for the development of chronic non-communicable diseases and the general recommendations for health promotion. Faced with the gaps in the scientific literature, it is recommended that future research be conducted on the impact of strategies to strengthen the social support network and opportunities for personal growth in the prevention of chronic diseases and health promotion of LHTDs in the post-COVID-19 pandemic period.
