Psychosocial Factors and Work-related Musculoskeletal Disorders among Southeastern Asian Female Workers Living in Korea

Developing an observational technique for Agricultural Ergonomics Risk Assessment (AERA)

BackgroundErgonomics risk assessment tools are vital for evaluating awkward postures in various industries, with a primary focus on biomechanical factors. However, existing observational techniques often fail to meet specific postural loading criteria or are inadequate to establish validity, especially in agricultural settings. Enhancements in these tools have been guided by extensive literature reviews.ObjectiveThis study aimed to develop a new assessment tool, the Agricultural Ergonomics Risk Assessment (AERA), by utilizing electromyography (EMG) to classify postural loads and prioritize risks.MethodThis paper describes an experimental study utilizing EMG to analyze postural loads, emphasizing biomechanical factors and including an evaluation of individual and occupational risk factors associated with musculoskeletal disorders (MSD). The validity and reliability of AERA were assessed by five experts and thirty evaluators.ResultsThe study revealed strong effects of varying loads and postures on muscle activation. A key finding was the application of biomechanical factors to assess risk levels associated with awkward postures, especially regarding the prevalence of MSD in the neck, trunk, and arm regions. The evaluation indicated a Cronbach's alpha coefficient of 0.97 for precision in content validity of risk assessment criteria. Reliability tests comparing AERA with OWAS, RULA, and REBA yielded Cronbach's alpha coefficients of 0.99, 0.84, 0.93, and 0.88, respectively.ConclusionAERA's evaluation criteria incorporating specific and comprehensive risk factors produced the highest levels of test-retest reliability, making it a valuable screening tool for the agricultural sector.

Pain as a Symptom of Mental Health Conditions Among Undocumented Migrants in France: Results From a Cross-Sectional Study

Objectives

This study aimed to explore the associations between mental health status and experienced pain among undocumented migrants (UMs) in France.

Methods

We used data from the multicentric cross-sectional "Premier Pas" study conducted in the Parisian and Bordeaux regions from February to April 2019. Participants over 18 years of age were recruited from sixty-three sites. Pain was assessed through two variables: overall pain and musculoskeletal pain. Mental health conditions, including anxiety, sleep disorders, depression, and posttraumatic stress disorder (PTSD) were evaluated. Logistic regression models were used to explore associations, controlling for social determinants of health (SDHs).

Results

Our findings revealed significant associations between mental health status and pain among the 1,188 included participants. Sleep disorder was associated to higher odds of musculoskeletal pain (aOR = 2.53, 95% CI [1.20-5.33], p = 0.014). Stratified results indicated that among women, depression was associated to higher odds of pain (aOR = 4.85, 95% CI [1.53-13.36], p = 0.007).

Conclusion

This large study confirms the connection between mental health status and pain among UMs, providing valuable evidence for clinicians to address mental health issues in this population.

Occupational Characteristics and Health Status of Vietnamese Male Migrant Workers in the Republic of Korea

Background

The objective of this study is to identify the working conditions and health status of Vietnamese male migrant workers in Republic of Korea, in comparison to the Korean general population.

Methods

We conducted our survey through the Migrant People Center, and we received completed questionnaires from 87 male Vietnamese migrant workers. The questionnaire employed was identical to those used in the Korean Working Conditions Survey and the 2020 Korea National Health and Nutrition Examination Survey. The collected data from the Vietnamese migrant workers was then compared with the Korean reference population using indirect age-standardization.

Results

Vietnamese male workers demonstrated a higher prevalence of health problems including hearing problems (age-standardized prevalence ratio (aSPR) 13.22, 95% confidence interval [CI]: 8.07-20.4), skin problems (aSPR 13.49, 95% CI: 8.07-20.4), and low back pain (aSPR 8.40, 95% CI: 6.50-10.69). Elevated exposure to workplace hazards such as chemicals (aSPR 2.36, 95% CI: 1.51-3.51), organic solvents (aSPR 2.22, 95% CI: 1.44-3.28), handling of heavy objects (aSPR 1.67, 95% CI: 1.24-2.21), and high temperatures (aSPR 1.96, 95% CI: 1.46-2.57) was observed among them. Additionally, they faced a higher risk of no personal protective equipment (aSPR 2.53, 95% CI: 1.26-4.52) and a greater prevalence of unmet medical needs (aSPR 7.14, 95% CI: 4.74-10.32).

Conclusion

Our findings highlight the elevated workplace hazards, health problems, and unmet medical needs among Vietnamese male workers compared to the Korean reference population. These findings underscores the urgency for enhanced scrutiny over working conditions and protective equipment provision, coupled with efforts to improve healthcare accessibility and worker education.

Interview survey of physical and mental changes and coping strategies among 13 Vietnamese female technical interns living in Japan

We conducted a case study to assess 1) physical and mental changes; 2) self-assessments of symptoms; 3) coping strategies; and 4) adaptation to physical and mental changes by semi-structured interview survey among Vietnamese female migrant workers working in Japan under the Technical Intern Training Program. We found they experienced female-specific physical changes, and some interns' symptoms worsened because they did not consult anyone about their symptoms. We propose increasing opportunities to learn about possible physical and mental changes caused by migration and to improve health literacy, including prevention, coping, help-seeking, and consultations about health concerns among female technical interns.

Association of work-life balance with occupational injury and work-related musculoskeletal pain among Korean workers

Background

The concept of work-life balance (WLB) has become an important issue in workers' health and safety. This study aims to investigate the relationship between WLB and occupational injury and work-related musculoskeletal pain.

Method

The study included 27,383 workers who participated in the Fifth Korean Working Conditions Survey. Participants were divided into good WLB and poor WLB groups based on their responses to the five question items which comprised two dimensions: work-on-life conflict (items, 1–3) and life-on-work conflict (items 4 and 5). Occupational injury and musculoskeletal pain were also assessed using the question items. The χ² test and multivariate logistic regression analyses were performed to examine the relationship of WLB to occupational injury and musculoskeletal pain while considering socio-demographic and occupational characteristics and ergonomic and psychological risk factors.

Results

Of the 27,383 participants, 252 (0.9%) had experienced an occupational injury and 6,408 (23.4%) had musculoskeletal pain. The poor WLB group had higher injury rates for both men (1.7%) and women (0.9%) than the good WLB group (1.1% and 0.4%, respectively). Additionally, the prevalence of musculoskeletal pain was higher for both men and women in the poor WLB group (25.2% and 28.0%, respectively) than for men and women in the good WLB group (18.7% and 23.6%, respectively). In the logistic regression analysis, the adjusted odds ratio of WLB for occupational injury was 1.37 (95% confidence interval [CI]: 1.06–1.78), and that for musculoskeletal pain was 1.14 (95% CI: 1.07–1.21), showing positive associations of WLB with both occupational injury and musculoskeletal pain.

Conclusions

Poor WLB causes an increase in occupational injury and musculoskeletal pain. Therefore, an improvement in WLB may reduce the incidence of occupational injury and musculoskeletal pain among workers. Social and policy-related initiatives are needed to improve workers' WLB to reduce occupational injury and musculoskeletal pain.

Health risk behaviors, musculoskeletal disorders and associated cultural adaptation, depression: a survey among Myanmar migrant workers in Chiangmai, Northern Thailand

Background and purpose

When migrants go to a new country to work, they experience transition of epidemiological risk factors, a new system of access to healthcare and changing life styles. Their comprehension of health risk factors will depend on acculturation pattern. Moreover, musculoskeletal disorders (MSDs) are significantly prevalent in such a population due to the manual work in their jobs. Myanmar immigrant’s acculturation level has not yet been studied in relation to prevalent diseases. This study aimed to investigate health risk behaviors, the prevalence of musculoskeletal disorders, and associated factors.

Methods

A cross-sectional study surveyed 414 Myanmar migrant workers in Chiangmai, Thailand. Face-to-face interviews administered structured questionnaires which comprised the transculturally validated East Asian Acculturation Measure scale, Standardized Nordic musculoskeletal questionnaires, Patient Health Questionnaires 2 and 9 for depression and questionnaires to screen health behaviors and jobs. Data analysis applied binary logistic regression.

Results

About 26.3% were current smokers and 40.8% current drinkers. Of the 75.8% of participants did not exercise, 40.1% were overweight and obese, 44.7% had prehypertension, 27.1% hypertension, and 13% had depression. The prevalence of MSDs at any site over the previous 12 months was 53.4% and it was significantly associated (P-value≤0.05) with female (adjusted odd ratio (aOR)=1.75; 95% confidence interval (CI)=1.04–2.94), depression (aOR=2.19;CI=1.10–4.39), marginalization pattern of acculturation (aOR=1.87;CI=1.09–3.21) and MSDs at any site last week (aOR=8.41;CI=4.09–17.30).

Conclusion

Health behaviors in this young, working migrant population are risky, and MSDs are common problems for migrant workers in northern Thailand. Findings of the current study highlighted health behaviors and cultural adaption as attributes to chronic, disabling, and common health problems of migrant workers. Public health interventions and recommendations considering this evidence may improve migrants’ health status, leading to better quality-of-life and productivity.

Occupational health outcomes among international migrant workers: a systematic review and meta-analysis

BACKGROUND

Globally, there are more than 150 million international migrant workers-individuals who are employed outside of their country of origin-comprising the largest international migrant group. A substantial number of migrants work in hazardous and exploitative environments, where they might be at considerable risk of injury and ill health. However, little data on occupational health outcomes of migrant workers exist, with which to inform global policy making and delivery of health services.

METHODS

For this systematic review and meta-analysis, we searched Embase, MEDLINE, Ovid Global Health, and PsychINFO databases for primary research published between Jan 1, 2008, and Jan 24, 2018, reporting occupational health outcomes among international migrant workers (defined as individuals who are or have been employed outside their country of origin), without language or geographical restrictions. We excluded studies containing mixed cohorts of migrants and native workers in which migrant data could not be disaggregated, and studies that did not explicitly report migrant status. The main outcome was prevalence of occupational health outcomes (defined as any injury, mortality, or physical or psychiatric morbidity due to an individual's work or workplace environment) among international migrant workers. Summary estimates were calculated using random-effects models. The study protocol has been registered with PROSPERO, number CRD42018099465.

FINDINGS

Of the 1218 studies identified by our search, 36 studies were included in our systematic review, and 18 studies were included in the meta-analysis. The systematic review included occupational health outcomes for 12 168 international migrant workers employed in 13 countries and territories, mostly employed in unskilled manual labour. Migrant workers originated from 25 low-income and middle-income countries, and worked in the following sectors: agriculture; domestic, retail, and service sectors; construction and trade; and manufacturing and processing. Migrant workers had various psychiatric and physical morbidities, and workplace accidents and injuries were relatively common. In the meta-analysis, among 7260 international migrant workers, the pooled prevalence of having at least one occupational morbidity was 47% (95% CI 29-64; I2=99·70%). Among 3890 migrant workers, the prevalence of having at least one injury or accident, including falls from heights, fractures and dislocations, ocular injuries, and cuts was 22% (7-37; I2=99·35%).

INTERPRETATION

International migrant workers are at considerable risk of work-related ill health and injury, and their health needs are critically overlooked in research and policy. Governments, policy makers, and businesses must enforce and improve occupational health and safety measures, which should be accompanied by accessible, affordable, and appropriate health care and insurance coverage to meet the care needs of this important working population.

'Aches and Pains' of Filipino Migrant Workers in Malaysia: A Profile of Work-Related Musculoskeletal Disorders

Background and Purpose:

Musculoskeletal disorders (MSDs) are alarmingly high among migrant workers in Malaysia. MSDs are the most prevalent occupational-related conditions in most parts of the world affecting function, productivity and overall health-related quality of life. Therefore, this study aims to determine the profile of Filipino migrant workers in Malaysia and their various musculoskeletal complaints.

Method:

This study utilized a quantitative, nonexperimental, cross-sectional research design. A total of 60 subjects were randomly selected after passing the study’s sampling criteria. The Nordic Musculoskeletal Questionnaire (NMQ) was to used to determine common MSDs affecting the various regions in the body. The Demographic Pofile Sheet was provided to gather a subject’s demographic characteristics.

Results:

Filipino migrant workers mostly complain of pain in the low back area (60%) and shoulder pain (60%), followed by pain in the upper back (48.3%) and neck pain (45%) in the last 12 months. Household workers accounting for 73.3% of the subjects commonly complain of pain in the hips/thighs (78.9%), while workers in the service industry commonly complain of knee pain (39.1%).

Conclusions:

Results imply that Filipino migrant workers have a higher prevalence of shoulder and lower back pain in the last 12 months. Household workers are more susceptible to hip/thigh pain. Interventions focusing on ergonomics policy implementation, education on posture and lifting techniques and physical function is recommended. Further studies should consider the psychological and psychosocial aspects of migrant employment, which are known risk factors for MSDs.

The Current Working Conditions in Ugandan Apparel Assembly Plants

BACKGROUND

The present rapid shift of industrialization from developed to developing countries requires developing countries to understand issues related to work organization, management, and working conditions. There are many factors slackening production, of which working conditions is part. A complete inquiry into the workers' working conditions can enable managements to reduce risks in the workplaces and improve productivity. Understanding and awareness of the benefits of workplace research and a probe into the working conditions in the Ugandan apparel assembly plants are urgently required.

METHODS

A total of 103 (70 women and 33 men) workers from five different plants were interviewed. Together with the top management of various plants, questionnaires about the workers' opinions of their physical working conditions were prepared. Data was collected using two methods: (1) questionnaire; and (2) observation of the workers during their work.

RESULTS

The results indicated that poor plant working conditions were mainly contributed by the workers' social factors and the management policies.

CONCLUSION

The government, together with the management, should work to improve the working conditions in the apparel assembly plants, as it greatly affects both.
