Individual Risk Assessment (ERIN)

Work-related musculoskeletal disorders (WMSDs) prevention has become a global phenomenon and nowadays is one of the main challenges that ergonomics and work safety professionals face. The evaluation of risk factors exposition related to the WMSDs is one of the main activities that are performed for prevention. In order to accomplish it, many ergonomic assessment methods have been developed. In this chapter, an ergonomic observational individual risk assessment (ERIN) method is presented, which is distinguished for being easy to learn, apply, and it needs short training time. Results on the reliability, validity, and usability studies of ERIN are included too, as well as an example of how it can be used in the workplace intervention process.

The effectiveness of nutrition and health intervention in workplace setting: a systematic review

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 was 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.

Pandemics at Work: Convergence of Epidemiology and Ethics

Like COVID-19, new infectious disease outbreaks emerge almost annually, and studies predict that this trend will continue due to a variety of factors, including an aging population, ease of travel, and globalization of the economy. In response to episodic public health crises, governments and organizations develop, implement, and enforce policies, procedures, protocols, and programs. The epidemiological triad is both a model of disease causation and fundamentally used to design and deploy such control measures. Here we adapt this model to the workplace setting and use the epidemiological triad to characterize the related ethical challenges in implementing the control measures employers face as a guide for a workplace intervention framework. Through this approach, our aim is to show how an integrated ethical framework, grounded in epidemiological principles, has important implications for how we categorize, understand, and resolve the difficult decisions that emerge in the workplace under pandemic conditions.

Process evaluation of a complex workplace intervention to prevent musculoskeletal pain in nursing staff: results from INTEVAL_Spain

Background INTEVAL_Spain was a complex workplace intervention to prevent and manage musculoskeletal pain among nursing staff. Process evaluations can be especially useful for complex and multifaceted interventions through identifying the success or failure factors of an intervention to improve the intervention implementation. Objectives This study performed a process evaluation of INTEVAL_Spain and aimed to examine whether the intervention was conducted according to the protocol, to investigate the fulfilment of expectations and the satisfaction of workers. Methods The intervention was a two-armed cluster randomized controlled trial and lasted 1 year. The process evaluation included quantitative and qualitative methods. Quantitative methods were used to address the indicators of Steckler and Linnan’s framework. Data on recruitment was collected through a baseline questionnaire for the intervention and the control group. Reach and dose received were collected through participation sheets, dose delivered and fidelity through internal registries, and fulfilment of expectations and satisfaction were collected with two questions at 12-months follow-up. Qualitative methods were used for a content analysis of discussion groups at the end of the intervention led by an external moderator to explore satisfaction and recommendations. The general communication and activities were discussed, and final recommendations were agreed on. Data were synthesized and results were reported thematically. Results The study was performed in two Spanish hospitals during 2016-2017 and 257 workers participated. Recruitment was 62 and 51% for the intervention and the control group, respectively. The reach of the activities ranged from 96% for participatory ergonomics to 5% for healthy diet. The number of sessions offered ranged from 60 sessions for Nordic walking to one session for healthy diet. Fidelity of workers ranged from 100% for healthy diet and 79% for participatory ergonomics, to 42 and 39% for Nordic walking and case management, respectively. Lowest fidelity of providers was 75% for case management and 82% for Nordic walking. Fulfilment of expectations and satisfaction ranged from 6.6/10 and 7.6/10, respectively, for case management to 10/10 together for the healthy diet session. Discussion groups revealed several limitations for most of the activities, mainly focused on a lack of communication between the Champion (coordinator) and the workers. Conclusions This process evaluation showed that the implementation of INTEVAL_Spain was predominantly carried out as intended. Process indicators differed depending on the activity. Several recommendations to improve the intervention implementation process are proposed. Trial registration ISRCTN15780649.

Genetic risk for obesity and the effectiveness of the ChooseWell 365 workplace intervention to prevent weight gain and improve dietary choices

ABSTRACT Background It is unknown whether behavioral interventions to improve diet are effective in people with a genetic predisposition to obesity. Objectives To examine associations between BMI genetic risk and changes in weight and workplace purchases by employees participating in a randomized controlled trial of an automated behavioral workplace intervention to promote healthy food choices. Methods Participants were hospital employees enrolled in a 12-mo intervention followed by a 12-mo follow-up. Hospital cafeterias utilized a traffic-light labeling system (e.g., green = healthy, red = unhealthy) that was used to calculate a validated Healthy Purchasing Score (HPS; higher = healthier). A weighted genome-wide BMI genetic score was generated by summing BMI-increasing alleles. Results The study included 397 adults of European ancestry (mean age, 44.9 y; 80.9% female). Participants in the highest genetic quartile (Q4) had a lower HPS and higher purchases of red-labeled items relative to participants in the lowest quartile (Q1) at baseline [Q4–Q1 Beta HPS, –4.66 (95% CI, –8.01 to –1.32); red-labeled items, 4.26% (95% CI, 1.45%–7.07%)] and at the 12-mo [HPS, –3.96 (95% CI, –7.5 to –0.41); red-labeled items, 3.20% (95% CI, 0.31%–6.09%)] and 24-mo [HPS, –3.70 (95% CI, –7.40 to 0.00); red-labeled items, 3.48% (95% CI, 0.54%–6.41%)] follow-up periods. In the intervention group, increases in HPS were similar in Q4 and Q1 at 12 mo (Q4–Q1 Beta, 1.04; 95% CI, –2.42 to 4.50). At the 24-mo follow-up, the change in BMI from baseline was similar between Q4 and Q1 (0.17 kg/m2; 95% CI, –0.55 to 0.89 kg/m2) in the intervention group, but higher in Q4 than Q1 (1.20 kg/m2; 95% CI, 0.26–2.13 kg/m2) in the control group. No interaction was evident between the treatment arm and genetic score for BMI or HPS. Conclusions Having a high BMI genetic risk was associated with greater increases in BMI and lower quality purchases over 2 y. The 12-mo behavioral intervention improved employees’ food choices, regardless of the genetic burden, and may have attenuated weight gain conferred by having the genetic risk.
