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.

BACKGROUND: Chemicals that enter the body, especially benzene, will undergo a detoxification process. Unfortunately, at the detoxification process, sometimes benzene can produce free radicals. Free radical oxidation of lipids produces MDA compounds (malondialdehyde). To overcome these free radicals, the body will adapt to produce Glutathione (GSH) enzymes. AIM: The purpose of this study was to analyse the relationship between benzene concentration, MDA levels and glutathione enzymes in Shoe-Maker Home Industry workers exposed to benzene for more than 10 years. METHODS: Measurement of benzene concentration using a gas chromatography-flame ionisation detector (GC-FID). MDA levels used a modified spectrophotometric and GSH method of thiobarbituric acid (TBA) test. RESULT: The results showed that the majority of respondents had benzene concentrations still below the TLV value, mean of MDA levels were 6.94 mg/ml, while GSH was 4.54 mg/ml. Benzene concentration did not have a significant correlation with MDA and glutathione levels, whereas MDA levels had a strong correlation with glutathione levels (p = 0.000; r = -0.947). CONCLUSION: Workers should always use PPE and always eat foods that contain lots of glutathione enzymes such as spinach or broccoli to reduce the impact of free radicals from benzene inhalation.

Background: Children in primary schools use school bags to carry study material, although the heavy bags are often associated with musculoskeletal problems, especially back pain. This practice requires strength, which significantly changes the body posture and walking pattern, subsequently leading to the incidence of back pain as a side effect. The aim of this study, therefore, is to analyze the differences in bag loads between elementary school children in urban and suburban area, and also analyze the relationship with the occurrence of back pain. Design and methods: This was a cross sectional study, which used stratified random sampling to choose 2 elementary schools each representing the urban and suburban areas. Furthermore, a total sample of 164 students were selected, whose school bag weight were measured for 5 consecutive days, particularly in the morning on respondents arrival at school. Moreover, the occurrence of back pain was evaluated using a modified Nordic map, and data analysis required the use of independent sample analysis t test and χ² test. Results: The results showed the presence of highly significant differences in the school bags weight of respondents in the urban and suburban areas, as well as between schools using the 2013 curriculum and otherwise. Conclusions: In conclusion, there is a correlation between the weight measured and the occurrence of back pain, hence the 2013 curriculum is recommended to be adopted by all elementary schools. Also, the use of lockers to store items used at school repeatedly by children is also highly encouraged.

BACKGROUND: Pencak Silat is a self-defense exercise originated from Indonesia and categorized as a high-intensity exercise. AIM: This research was intended to identify the acute response of Pencak Silat basic exercise toward interleukin-6 (IL-6) as an immune system biomarker on students of Perguruan Pencak Silat Perisai Diri Tulungrejo, Bojonegoro. METHODS: A number of 26 students (10 boys and 16 girls) of Perguruan Pencak Silat Tulungrejo, Bojonegoro, were participated in this study. The students did the 2 h Perguruan Pencak Silat Perisai Diri, Bojonegoro, training program with 75–85% intensity. The IL-6 serum was measured using ELISA method. RESULTS: The result of this study showed that the IL-6 serum level in post-2 (12 h after training) (6.2981 pg/mL) was higher compared with the IL-6 serum level in post-1 (shortly after training) (6.11981 pg/mL) and before training (4.5146 pg/mL). The result also showed that there was a significant difference of IL-6 levels between pre-training and after training. CONCLUSION: This study concluded that the basic exercise performed by the new students of Perguruan Pencak Silat Perisai Diri increased IL-6 serum level.

The perception of risk is an important element of many theories about changing safety behavior. Perceived risk is often subject to survival behavior change interventions. The perception of risk to occupational safety and health is an important factor in the success of the work accident prevention program. Risk perception is an important determinant of safety behavior, although the nature of the relationship between risk perception and safety behavior may depend on the profile of different types of risk perception and the accuracy of the perception. The perception of workers, both permanent and non-permanent workers, on occupational safety and health and accident prevention with risk perceptions is an important factor in the success of this accident prevention program. This study aims to find out more about adapting the TRIRISK model for intentionally perceived risk in the context of perception. By assessing the role of the deliberative, affective, and experiential dimensions of safety and health risks in the workplace. Quantitative research was conducted by means of a survey with a questionnaire. The survey was conducted from November to December 2021 and obtained as many as 102 respondents.

Background: Firefighting is one of the jobs that have a high risk of experiencing work fatigue. This is because firefighters are required to be able to complete their work optimally and carefully. Firefighters who experience work stress and bad sleep quality can increase the risk of work fatigue. Objectives: This study aims to determine the relationship between sleep quality and work stress with work fatigue in firefighters at the East Jakarta Fire and Rescue Service. Methods: This study is an analytical observational study with a cross-sectional study approach. The sample in this study was determined using a simple random sampling technique on the workers of the Sub-Unit Members of the Fire and Rescue Service at the East Jakarta Fire Department with various criteria, so that 40 people were obtained. Results: Data analysis using Chi Square and Rank Spearman analysis techniques showed that there was a significant relationship between sleep quality and work fatigue (p value = 0.027 < 0.05) and there was a significant relationship between work stress and work fatigue (sig. (2-tailed) = 0.000 < = 0.05). Conclusions: It was concluded that there is a relationship between sleep quality and work stress with work fatigue on firefighters of the East Jakarta Fire and Rescue Service Department.
