Mental and self-rated health of bakery workers in Lebanon: A national study

Work-related musculoskeletal disorders and related risk factors among bakers: A systematic review

BACKGROUND

Work-related musculoskeletal disorders (WRMSDs) and ergonomic risk factors are very common in bakery workers.

OBJECTIVE

The purpose of this study is to (1) assess the prevalence of musculoskeletal disorders among bakers because they use automated machines or traditional baking, and (2) to determine the strategies to prevent musculoskeletal disorders in bakers.

METHODS

A systematic review of PubMed, Scopus, and Web of Science was conducted from the beginning to February 4, 2022, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Mesh keywords and phrases were used to execute the search strategy. Information on MSDs and ergonomic risk factors in bakery workers was collected. Two reviewers worked independently on study selection, data extraction, and paper quality ranking.

RESULTS

This study identified 14 papers from seven countries. Although the prevalence of MSDs in bakery workers has been studied, only a handful of them have been studied ergonomic risk factors, and the findings have been very limited. The association between different risk factors and MSDs seemed significant compared to many other occupational diseases. The traditional bread-baking system and lack of mechanization may increase the risk of MSDs in bakery workers.

CONCLUSION

WRMSDs for bakery workers have been less studied than other occupational diseases. Our systematic review found several significant relations between the factors influencing the prevalence of MSDs. This study also showed the comparison of traditional and modern cooking systems with diseases of the upper limbs, shoulders, and back pain as possible fields for future research.

The Effect of Awkward Postures and Musculoskeletal Disorder Incidents: A Case Study of Bakery Workers

Musculoskeletal complaints or MSDs are common in the bakery industry. Observations and analyses of work posture among bakers are crucial to determine the most practical solution to MSD subjective complaints. This study aims to analyze the impact of work posture on musculoskeletal events in bakery industry workers. This research is quantitative research with a cross-sectional approach. This study recruited 52 bakers. Work posture data was obtained by utilizing the Rapid Entire Body Assessment (REBA) instrument. The subjective musculoskeletal complaint data were collected using the Nordic Body Map (NBM) instrument. The results indicated that most workers (90.4%) were in the young category, 67.3% were male, and 51.9% had a long permanent contract. Most respondents are in the high ergonomic risk category (75%). The lower back (63.5%), neck (25%), and ankle (25%) were subjectively reported by the respondents using the NBM instrument. There was no significant relationship between ergonomic risk and MSD complaints (p-value = 0.721 at α = 0.05). The bakers were exposed to ergonomic limitations and experienced some subjective MSD complaints. However, no significant association was found between ergonomic work posture limitations and MSD complaints. The non-significant finding might be related to the small sample study size or the measurement bias.

Mental health in Lebanon: Tomorrow's silent epidemic

Lebanon is a middle-income country that has been recently crippled by several tragedies including the economic collapse, COVID-19, and the fourth of August Beirut port explosion, the world’s most powerful non-nuclear explosion of the twenty-first century. Recent data on mental health from Lebanon is summarised, and other topics such as the psychological impact of cumulative adversities and the role of international support in Lebanon are examined. Data from Lebanon shows severe levels of distress among the people, in a country with minimal resources. Given current adversities in Lebanon, recent data in the country, and the literature on adversity and mental health outcomes of man-made disasters, Lebanon is most likely going to face an epidemic in poor mental health. A call is made for the wider scientific community and international organizations to support the mental health field in the country and help prevent further negative mental health outcomes. Understanding how to better navigate mental health in places with extreme adversity and emergencies can be beneficial to other communities which might face similar challenges.

Longer leisure walking time is associated with positive self-rated health among adults and older adults: a Brazilian nationwide study

Background

To verify the association between weekly leisure walking time and positive self-rated health in the Brazilian adult and elderly population.

Methods

This cross-sectional study used information collected in 2019 across all regions of Brazil. This study included 25,785 people aged ≥ 18 years (mean = 51.6; standard deviation = 18.0) from all capitals of the Brazilian states who reported practicing walking as physical activity during leisure time. Self-rated health was the dependent variable (positive or negative). The leisure walking time/week was the main exposure and it was categorized in “150 minutes/week”, “150–299 minutes/week” and “≥ 300 minutes/week”. We used binary logistic regression to estimate odds ratio (OR) and 95% confidence intervals (95% CI) that was adjusted for relevant covariates.

Results

We found that individuals who reported leisure walking for a period from 150 to 299 minutes/week and those who reported walking for a period ≥ 300 minutes/week were respectively 28% (OR = 1.28. 95% CI [1.10–1.48]) and 52% (OR = 1.52. 95% CI [1.27–1.82]) more likely of perceiving their health positively compared to those who reported walking for a period < 150 minutes/week. Individuals who reported leisure walking time <150 minutes/week had 72.3% (95% CI [70.4–74.1]) probability of perceiving their health positively. Individuals who reported leisure walking time from 150 to 299 minutes/week had 76.6% (95% CI [75.0 –78.3) probability of perceiving their health positively. On the other hand, individuals who reported leisure walking time ≥ 300 minutes/week had 79.2% probability (95% CI [77.1–81.4]) of perceiving their health positively.

Conclusion

Longer leisure walking time was associated with positive self-rated health among adults and older adults in Brazil.

Heat Stress-Related Symptoms among Bakery Workers in Lebanon: A National Cross-Sectional Study

Heat exposure is linked to a range of heat-related illnesses and injuries. This study assessed the association between workers’ perceptions of the work environment and reports of heat stress-related health symptoms in bakery workers in Lebanon. A national cross-sectional survey of workers was carried out in 504 bakeries in Lebanon. One worker in each bakery was interviewed using questions relating to the workplace environment and heat stress-related health symptoms. Heat and humidity measurements were recorded in bakeries. Descriptive analyses were performed, and logistic regression assessed relationships between the workplace environment, worker perceptions, and reports of heat stress-related health symptoms. In total, 47.2% of workers experienced heat stress-related symptoms, 83% perceived workplace temperatures as hot, and 48% perceived these temperatures as affecting their health. Humidex readings showed that 49% of bakeries had conditions unsafe for routine work tasks. Working under pressure (AOR = 1.65; 95% CI = 1.12-2.43), job dissatisfaction (AOR = 1.76; 95% CI = 1.12-2.79), and perceptions that high temperatures negatively affected health (AOR = 2.73; 95% CI = 1.87-3.99) were all significantly correlated to reports of heat stress-related symptoms. Females were more likely to experience heat stress-related symptoms (AOR = 1.96; 95% CI = 1.13-3.39). Workers who reported low levels of water consumption at work were also more likely to experience heat stress-related health symptoms. We conclude that heat exposure potentially impacts workers’ health in Lebanese bakeries. Improvements in workplace conditions, adequate infrastructure, and workers’ training are key interventions for maintaining workers’ health.
