Nosotros, como futuros profesionales, elegimos el tema nutrición en el área (o momento) laboral. Creemos que es un tema que hoy en día le compete a todo aquel adulto que trabaje, y, es que, con la rutina diaria, el ir y venir, y los horarios que tenemos; el alimentarnos correctamente no es siempre posible. La mayoría de las personas que trabajan y además tienen otras actividades en el día, no pueden tener una nutrición correcta en cuanto al aporte de nutrientes que debería tener, ni tampoco en las cantidades que debería comer, y, en la actualidad, los momentos de la comida no son en los horarios que deberían ser (por ejemplo, el almuerzo al medio día, o las meriendas), lo cual en conjunto afecta considerablemente en la salud, el funcionamiento y la eficacia, disminuyendo la calidad de vida del trabajador. Los más afectados con esto son aquellos que cumplen la labor de forma sedentaria, los cuales, al tener menor actividad física respecto a otros, son más propensos a sufrir enfermedades como hipertensión, diabetes, cardiopatías, accidentes cerebrovasculares o problemas en las articulaciones. Así que creemos que es importante abordarlo, ya que es necesario alimentarnos bien para poder funcionar lo mejor posible en cada área que nos desarrollemos.

Abstract

Health status of workers are crucial to maintain their productivity and it will impact on output per capita. This systematic review aims to evaluate the effectiveness of nutrition and health intervention in workplace setting and implication for further research. Articles were searched from PubMed, PMC, Cochrane Library (Trial), Science-direct, and Google scholar published from 2005-2020. Inclusion criteria were the intervention subject aged 19-64 years old with experimental randomized control trial (RCT) or non-RCT study design. Several keywords used for literature searching including "nutrition education in workplace", "nutrition intervention in workplace", and "workplace intervention". Data were narratively described. Eleven studies were meet inclusion and exclusion criteria and further be reviewed. Five studies focused on intervene food environment in the workplace, four studies focused on nutrition education using different channels i.e., workplace visiting and emails, the other two interventions were objected to decrease health risk regarding occupational health. Positive outcomes were recorded for all workplace intervention, including increase in nutrition knowledge, self-efficacy, reduce risky behavior, and also improved body mass index and blood biomarkers. Workplace nutrition and health intervention proved to be an effective way to enhanced balanced nutrition behavior and improve health status. This study implies an urgency of nutrition and health intervention in a workplace.

This systematic review proved several nutrition and health intervention in workplace setting that resulting in improvement of healthy behavior, anthropometric and biochemical indicators. Further, nutrition and health intervention can be implemented in workplace as a way to increase work productivity, reduce the disease burden costs of employee, and improve general health status.

Key words: Behavior, nutrition intervention, occupational health, workers, obesity

Introduction

Based on social determinant of health concept, workplace is one of the places that could affect wide range of health, functioning, and quality-of-life outcomes and risks.1 It is strengthened by the WHO which described a workplace as a priority environment to influence dietary behaviors given that individuals can spend up to two-thirds of their waking hours at work.2 Tompa3 in his publication revealed that health status could directly impact workers' productivity which can be measured using output per hour worked, output per paid labor hour, output per worker, and output per labor force participant. In the end, those level of workers' productivity will impact on output per capita as a measure of standard living. Potential health problems among workers are work accident, occupational illness, non-communicable diseases and communicable diseases.4A good health status not only impact on individual but also for the workplace itself. Several strategies that could be used for improving workers' productivity including improving nutrition, sanitation, education, health promotion, healthy workplace, occupation-health and safety, and population health.

Indonesia's latest national survey in 2018 reported the highest non-communicable diseases among productive age was hypertension, followed by stroke, joint diseases, cancer, and diabetes. Moreover, 35.4% of adults reproductive age are overweight/obese.5 Overweight/obese found to be the dominant factor of metabolic syndrome which defined as metabolic disruption including hypertension, type 2 diabetes, central obese, high triglyceride level and low HDL cholesterol level.6 American College of Occupational and Environmental Medicine (ACOEM) explained that the workforce supports the financial underpinnings of healthcare system and drives the country's economy. Thus, building a preventive-based strategy to enhance workers' health and productivity is a crucial investment.7

Workplace nutrition intervention had the highest positive effect on health behaviors as mentioned by The American Heart Association.8 Further, AHA also describe a guideline of workplace nutrition intervention including the use of well-balanced meals (low-fat dairy products, low saturated fat and avoiding trans-fat, more fruits and vegetables, whole grains, seafood, lean meats and poultry, as well as salt alternatives. At least two studies revealed that workplace nutrition intervention bettered workers' diet and physical activity which could decrease the risk factor of cardiovascular diseases.9,10 Moreover, Hochart and Lang11 mentioned that nutrition education program in worksite able to increase work efficiency, lowering absenteeism and employees' healthcare cost. Hence upon, a behavior enhancing nutrition and health status of the workers should be implemented in every workplace. Further implication on the emergence of health and nutrition intervention in a workplace need to be assessed. To our knowledge, currently there are not many systematic reviews that focus on nutrition education in the workers, but focuses on vulnerable age groups such as school children, adolescents and pregnant women. In results, not many companies or small to medium enterprises (SMEs) that having nutrition and health education as their primary policy. Thus, this study aims to review the efficacy of health and nutrition intervention among workers that result can be used as the evidence based for policymakers to start implementing health and nutrition education periodically.

Methods

Articles were searched from five electronic databases i.e., PubMed, PMC, Cochrane Library (Trial), Science-direct, and Google Scholar. An online search was conducted in March 2020 for all intervention articles on workers published in 2005 - 2020. Several keywords used for literature searching including "nutrition education in workplace", "nutrition intervention in workplace", and "workplace intervention". This study did not limit the outcomes presented by the authors in the articles found. Figure 1 represents the article search flow chart.

Inclusion and exclusion criteria

The literature review aims to answer research questions "how is the effectiveness of interventions carried out in a workplace setting?". Studies to be included in this review had to match predetermined criteria according to the PICOS approach. Criteria for inclusion and exclusion are specified in Table 1 .

Data Extraction and data synthesis

Five electronic databases were searched up until March 2021. Key words identified studies intervening to improve nutritionrelated outcomes for industrial workers. Two reviewers worked independently of each other to assessed articles independently for inclusion and study quality and extracted data. Only studies published in English were included. Data were summarized narratively. There was no disagreement between two reviewers.

Results

Study selection

Initially, we subsequently screened 870 titles and abstracts described about workplace intervention through different electronic databases including PubMed, PMC, Cochrane Library (Trial), Science-direct, and Google Scholar. Of these, 775 were excluded due to uncorrelation with nutrition and health topic and/or published less than year 2005. We assume that a study longer than 2005 might be not suitable with recent conditions. Then, full text paper of 45 articles were following next review. Thirty-six articles were excluded due to the following reasons: non-experimental study or cross-sectional study, reviews, and unrelated studies. Thereafter, the full texts of 11 studies were assessed for eligibility and included in this systematic review.

Study characteristics

All 11 included studies were experimental study, eight studies using control-group and other two not measuring the control group.12-23 All of intervention study reviewed were able to prove the positive outcome of workplace nutrition and health intervention. Minimum duration taken for experiment study in workplace setting was 8 weeks (or 2 months) and the longest period of intervention was 3 years. This review included 11 articles from 11 different countries including South Korea, Iran, Bangladesh, Taiwan, Spain, the United States, Cambodia, Denmark, Canada, Brazil and Ireland. The most prevalent measurable outcomes were knowledge, behavioral change related to nutrition and physical, body mass index and several anthropometric and biochemical measurements. Ten studies assigned workplace's employees as the participant and only one study in which respondent was cafeteria manager. Most of the study measure behavioral outcome as it could last longer and maintain the respected behavior in workplace. Based on the type of intervention, there were four different types of nutrition and health intervention in workplace namely education and behavioral change program, meal intervention, exercise intervention and a combination of several intervention. Table 2 showed the details of each study.

Education and behavioral change program

Five studies were focus on giving education and behavioral intervention with different approach and time frame. A study in South Korea provided a nutrition counseling for male workers for 4 consecutive months. Nutrition education was conducted in a selfdirected coaching method, anthropometric and biochemical assessment was done before counselling session, as well as dietary habits. Each worker was visited 2 times with 20 mins for each session. Mean intake during intervention was 2160 kcal of energy, 321.3 g of carbohydrate, 79.7 g of protein, and 61.8 g fat (ratio 60:15:26), 15 g of fiber. This study results a significant decrease in body mass index, fasting blood sugar, total cholesterol and LDLcholesterol after nutrition education.12 Aligned with previous study, Hassani et al.13 also observed an increase in nutritional knowledge, improved dietary intakes, fasting blood glucose and homocysteine levels after 3 months educational workshop intervention. This study was done in five training sessions focusing on the limitation of trans-fats, saturated fats and simple carbohydrates, increasing the consumption of fruits/vegetables and whole grains while highlighting the importance of breakfast and healthy snacks through educational classes at work. The educational method used in this study included lectures, question/answer sessions and group discussion. The longest workplace intervention in this review was 3 years, done in 12 work centers in Spain and started in 2008.24 The study emphasized on health promotion and health monitoring, which included alcohol and drug awareness and the evaluation and monitoring of alcohol and drug consumption. Each worker given 5 hours awareness training session. This study was done considering high intake of alcohol and drugs among workers could increase risk of work accidents, absenteeism, work incapacities and decreased productivity. After intervention and close monitoring, positive result shown at the first year after intervention where the number of risky alcohol consumption was decrease and keep reducing over 3 years follow up.17 A different intervention approach for education program was done in Brazil. Instead of the workers, cafeteria's managers were educated to change the food environment in 29 companies for 6 months. This intervention succeeded to increase fruits and vegetable availability up to 49 g, while no change in control group and also gives a positive result in increasing fruits and vegetable for 11 g.22

A quasi-experimental mixed method study

1310 non-pregnant female RMG workers from four factories

(A) Lunch meal intervention package: daily nutritionally-enhanced (with fortified rice) hot lunch, once weekly iron-folic acid (IFA) supplement and monthly enhanced (with nutrition module) behavior change counseling (BCC) versus (B) lunch meal control package: regular lunch and BCC; and (C) non-meal intervention package: twice-weekly IFA and enhanced BCC v ersus (D) non-meal control package: BCC alone. (n=326)

(A) Lunch with regular rice and regular behavior change counseling (BCC) (B) regular BCC only (n=328)

10 months

Anemia was reduced significantly in both lunch meal and non-meal intervention (A and C) group (DID: 32 and 12 percentage points, p<0.001 and <0.05, respectively). The mean hemoglobin concentration also significantly increased by 1 gm/dl and 0.4 gm/dl in both A and C group (p: <0.001 respectively). Weight did not change in the intervention groups (A and C) but significantly increased by more than 1.5 kg in the comparison groups (B and D).

Peters et al.17

A matched-pair cluster randomized controlled trial

607

Five intervention groups The ARM intervention contained two main intervention components: (1) the Soft Tissue Injury Prevention Program (StIPP) which focused on improving ergonomics practices at the site and worker level to improve musculoskeletal health; and (2) Health Week, that integrated key messages and provided integrated health coaching opportunities for individual workers to improve ergonomic practices and improved health behaviors (diet, physical activity, and smoking) associated with cardiovascular health (n=283)

Five control groups (no intervention) (n=324)

6 months

There was a difference in favor of the intervention group for a reduction in physically demanding work (B = -0.25, p=0.008), increased recreational physical activity (B = 35.2, p=0.026) and higher consumption of fruits and vegetables (B = 0.87, p=0.008).

Geaney et al.22

A cluster-controlled trial

Four large, purposively selected manufacturing workplaces

Three different interventions i.e., nutrition education (education) (n=226), environmental dietary modification (environment) (n=113) and nutrition education and environmental dietary modification (combined) (n=400)

No intervention

9 months

There were significant positive changes in intakes of saturated fat (p=0.013), salt (p=0.010) and nutrition knowledge (p=0.034) between baseline and follow-up in the combined intervention versus the control. Small but significant changes in BMI (-1.2 kg/m2 (95% CI -2.385, -0.018, p=0.047) were observed in the combined intervention.

Another nutrition education in a workplace context was done using email. The intervention group received one physical activity and one parallel nutrition message per week for 12 weeks; while the control group received no weekly messages. Several messages sent through employee's email were active living, balanced nutrition, increase fruits and vegetable intake also reduce fat intake. The email-based intervention study proved to increase worker's selfefficacy in healthy eating habits and physical activity21.

Meal and/or supplement intervention

There were three interventions in a workplace focusing on meal and/or supplement intervention. An RCT dietary intervention trial by giving meal replacement made from white sweet potato for lunch and dinner, added two packs of shakes. In this intervention, all workers were also instructed to restrict daily energy intake up to 1200 kcal for women and 1500 kcal for men. After eight weeks of intervention, both intervention and control group showing a decrease of body weight, body fat, body mass index, wrist circumference, thigh circumference, calf circumference, mid-arm circumference, and triceps skinfolds, but intervention group resulted higher decrease than the control. In addition, the intervention group with meal replacement resulted a decrease in glycated hemoglobin levels which could reduce the risk of type 2 diabetes. This study able to showed a significant result due to the high compliance of the workers.15 Ferrara16 described that adherence on meal replacement program might influence by individual self-efficacy, outcome expectations, and social communication.

Hossain et al.14 did a quasi-experimental mixed method study among female workers by providing lunch meal, iron-folic acid supplement as well as behavior change counseling. After 10 months of intervention, the mean hemoglobin and anemia was decreased significantly in both lunch meal and non-meal intervention, but no change in weight. Lunch meal provided for the intervention group consist of green leafy vegetables, lentils, fortified rice, fortified oil, and iodized salt every day and flesh foods at least three times a week. Another RCT among female garment workers that was done by providing lunch set (stir-fried dish, a soup, a side item (cooked rice), and a fruit dessert). The lunch was given for six months with total approximately 700 kcal in the canteen using local Cambodian food. Lunch provision for female workers proved to increase intake of vitamin-A rich fruits, dark green leafy vegetables, oil and fats; but contrary lowering the intake of flesh meats, legumes, nuts and seeds, and sweets.19

Exercise intervention

One cluster-RCT intervention in a workplace setting known to have focused on worker's physical activity. An intervention was focused for production unit employees whose having high prevalence of neck and shoulder pain. This study involving 537 workers implement 20 weeks of high-intensity strength training for the neck and shoulders three times a week (each 20 min) for a worker with high prevalence of neck and shoulder pain. Strength training was introduce by the Experienced instructors before conducted by the workers. High intensity training program shown in Figure 1 . High-intensity strength training relying on principles of progressive overload can be successfully implemented at industrial workplaces, and results in significant reductions of neck and shoulder pain compared to control group without training.20

Combination of several intervention

The last two out of eleven studies in this review focused on mixed intervention.18,23 A matched-pair cluster randomized controlled trial on commercial construction sites called All the Right Moves (ARM) intervention. The ARM intervention contained two main interventions, namely the Soft Tissue Injury Prevention Program (StIPP) which focused on improving ergonomics practices at the site and worker and Health Week that integrated key messages and practices and improved health behaviors (diet, physical activity, and smoking) associated with cardiovascular health.18 The ARM intervention managed to reduce physically demanding work, increase recreational physical activity and also increase consumption of fruits and vegetables. The other RCT study targeting four different workplaces undergone three different interventions namely nutrition education, environmental dietary intervention, and combination of both for 9 months. Better results were shown by the combination group; in which improving saturated fat and salt intakes, increase nutrition knowledge, also body mass index.23

Discussion

The results of this review showed that the intervention given in a workplace setting in the form of nutrition and health education, meal and/or supplement replacement, physical activity and combination type of intervention all gives a positive outcome. Several positive outcomes proved by several studies in this review including improved nutrition knowledge, improvement of anthropometric indices (decrease body mass index, body fat, wrist circumference, thigh circumference, calf circumference, mid-arm circumference, triceps skinfolds), improvement of biochemical indices (fasting blood sugar, HbA1C, total cholesterol level, LDL-cholesterol level, hemoglobin level), reduce risky behavior (alcohol intake, salt, saturated fat), increase dietary diversity score, higher intake of fruits and vegetables as well as fiber and vitamin A, elevate selfefficacy of doing physical activity and balance eating, reduction in physically demanding work and increased recreational physical activity, decreased neck and shoulder pain intensity.12-23

Most of the studies undergone in this review employed a large sample size, thus, able to showed a significant change. Only two studies out of 11 that employed less than 100 respondents (75 vs 58, respectively).12,15 Similarly, the absence of comparison/control group were shown in two out of 11 studies although those two studies mentioned still able to captured a significant results of workplace intervention.12,17 However, the use of control group in intervention study could better the study design since it could minimize biases and variability of factors that may influence intervention trial outcomes the bias of intervention effect.25

The success of one intervention in twenty-nine workplaces is not only mainly due to the change of food environment by modifying fruits and vegetable availability but also combining with the advertisement of health food and involving workers in meal planning and management.26,27 To date, changing the workplace environment still offered a great potential for promoting healthy nutrition. 28 It is again supported by the result of Gaeney et al.'s study29 among manufacturing workplaces that proved a positive outcome from environment modification after 9 months. Environmental dietary modification included five elements: i) menu modification: restriction of saturated fat, sugar and salt; ii) increase in fiber, fruit and vegetables; iii) price discounts for whole fresh fruit; iv) strategic positioning of healthier alternatives; and v) portion size control. 29 Other environment intervention was repositioning certain healthy foods within the canteen i.e., confectionary products were replaced with healthy snacks (fresh fruit, dried fruit, natural nuts) by the cash registers. The environment modification combined with nutrition education focused on with aim focused on how they can make a healthy food choice within a modified workplace environment. Those study revealed a significant positive changes in intakes of saturated fat, salt and nutrition knowledge between baseline and follow-up in the combined intervention versus the control. Small but significant changes in BMI were also observed in the combined intervention.29 It is further described that improvement of fasting blood sugar after a nutrition intervention might be mediated by the higher intake of fiber and low glycemic index food, with overall control on energy intake and body weight.30 However, this study did not mention the pre and post intervention intake, thus we cannot conclude the causation between nutrition education intervention and blood glucose improvement. Another study using email-based nutrition education in weekly basis for twelve weeks able to increase worker's self-efficacy in healthy eating practice and physical activity. In addition, self-efficacy is an important factor to build a better nutrition behavior based on social cognitive theory.31 It is explained that E-mail-based health interventions hold particular promise because they could reach large numbers of workers and can provide immediate feedback to participants.21 Although, computer literacy of the workers might be an important issue to address this email-based intervention.32 To our knowledge, email-based nutrition intervention is easier to carry compared to other intervention, also does not need many resources such as manpower and money, and able to reach out many employees, therefore, it is possible to be carry out in many workplace settings. A newly published review also concerned the use of digital technology might be beneficial to increase worker's physical activity and decrease sedentary behavior in the workplace setting.33

Another type of nutrition intervention carried out is meal replacement. Meal replacement defined as portion and caloric controlled meals which suitable to use for overweight people in controlling the calorie intake.34,35 Environmental change especially food environment could benefit the health of employee and lower the risk of non-communicable diseases. Another six studies also demonstrated the intervention was done in working environment. Hossain et al. study among female workers was claimed as the first nutrition intervention study in Bangladesh conducted, which showed the effectiveness of a combination of interventions to reduce anemia.14 Micronutrient-fortified rice given to the female workers can be a significant source of dietary bioavailable iron that improved hemoglobin level.36 The positive results of the study imply the continuation of the program especially for female workers to reduce the burden of anemia with minimum 10 weeks of supplementation, nutritionally-improved lunch meal, and education. Decrease intake of flesh meats might not be beneficial for the female workers considering the important role of iron for woman in reproductive age. The quantities of lunch meal given might have not been sufficient to meet the RDA for iron as reported for Cambodian women in rural areas.37

Lastly, physical activity intervention in our review able to showed a better profile on neck and shoulder pain since the workers were in high risk of neck and shoulder pain;20 another one RCT, the Soft Tissue Injury Prevention Program (StIPP), which focused on improving ergonomics practices at the workplace proved to reduce physically demanding work and increased recreational physical activity.18 Both studies given an intervention based on the worker's need, considering the type of work that might worsen their health status. Therefore, further study focusing on physical activity intervention should also do an initial assessment to determine the need of the workers. A study among employees from different workplace setting in Australia revealed that working hours were mostly spent sedentary (77.0%) which could bring potential health risk burden.38 Previous study revealed that strategy such as standing meetings could be used to reduce sitting hours in a workplace setting; however, several barriers were identified in applying those strategy such as workload pressure and workplace social norms.39 Furthermore, a meta-analysis of workplace physical activity intervention describes several positive effects of workplace physical activity intervention including physical activity behaviour, fitness (VO ₂max), anthropometric measures, work attendance, and job stress (0.33).40 Beyond it health benefits, promoting physical activity and reducing sedentary activity also promote social, mental, and economic domains which benefits organization itself.41 Consequently, it is urge to do physical activity intervention in a workplace setting.

A publication in 1986 did not prove the long-term benefit of nutrition intervention to change behavior or improve health,42 but our review found that nutrition intervention is now prove to improve both behavior and health such as practicing healthy eating (more fruits and vegetable, less saturated fat/high fat food), balancing food intake with activity level, and reduce alcohol intake. This review proposed the development of research and science which prove both short and long-term benefit of nutrition intervention. In addition, another review43 suggests the success of nutrition intervention in the worksite should pay attention to appropriate design and theory, focus on <3 objectives; duration more than equal to 5 months; whereas in our study, 4 studies were done <5 months, but mostly have <3 objectives and all resulting in positive outcomes.

Similar to our review, Robroek44 also conclude that a review related to worksite health promotion programmes is essential to developed a specific health programme based on each worksite needs. Nevertheless, an effort to increase workers participation need to be considered because of their low participations. Another review that in line to our study suggest that diet-related workplace interventions have positive effects on workers' nutritional knowledge, food intake and health, increase productivity, reduced absenteeism and presenteeism.45

We note some strength in our study including the variety of health and nutrition intervention that resulting in positive health outcome ranged from anthropometric change to biochemical change and also most importantly, behavioral change. This systematic review can be used as the material to advocate nutrition and health interventions in the office. However, some limitations are also followed, i.e., risk of bias strategy was not present. Reviewers was assessed articles included using PICOS strategy only. Other than that, we only consider articles that were published in English, so that, there is a possibility that some recent and important findings published in languages other than English were left out.

A short- and long-term benefit of nutrition and health intervention in the workplace suggests the importance of its implementation specially to improve employees' productivity and reduce burden cost. Therefore, our review can be used by the company to start and tailored nutrition/health intervention. In the bigger level, it can be used for policy makers to develop regulations that require all companies to carry out nutrition / health interventions.

Conclusions

In conclusion, this review imply that workplace may provide an optimal setting to reach a large proportion of the adult population thus could improve both nutrition literacy and practice as well as health status. Workplace interventions related to nutrition, physical activity, and health reviewed in this paper all gives different positive outcomes from knowledge and self-efficacy elevation, behavior change especially in increasing fruits and vegetable intake, reduce fat intake, avoiding alcohol and drug consumption, and starting a balanced nutrition habit. Moreover, workplace intervention could also address ergonomic related work problem considering the health problem that might arise among workers. Comparing different type of intervention studies, a combination of education-behavioral change program and work environment modification seems to results better outcome. Modify the future research by focusing on matching workers' needs in terms of nutrition and health behavior might be done to benefit the industry. Moreover, assess the population with high-risk nutrition problem in the workplace might also needed to focusing the nutrition intervention program.
