Prevalence of musculoskeletal disorders amongst flower farm workers in Kenya

Work-Related Musculoskeletal Disorders Among Farmers in the Southeast Asia Region: A Systematic Review

Background

Southeast Asia has many people who work in the agriculture sector. Not many stakeholders pay special attention to the health of farmers, even though they are exposed to various types of hazards. One of the most common health complaints among farmers is related to work-related musculoskeletal disorders (WMSDs). This study aims to assess the prevalence of WMSDs and factors associated with them among farmers in Southeast Asia.

Methods

A literature search on PubMed, ScienceDirect, Scopus, and EBSCO was conducted. Articles were included if they studied ergonomic problems among farmers from 11 countries in the Southeast Asia region and were published during 2015-2022. The Critical Appraisal Skills Program was used to evaluate the quality of the articles. The search process and retrieval process reflected PRISMA's recommendation.

Result

There were 14 studies found from 3 countries that had published articles in PubMed and ScienceDirect, including Thailand [8], Indonesia [4], and Malaysia [2]. The prevalence of WMSDs in Thailand, Indonesia, and Malaysia was 78,31%, 81,27%, and 88,39%, respectively. Common factors associated with WMSDs include age, sex, smoking habits, drinking alcohol habits, working period (years), type of work, awkward position, non-ergonomic equipment, repetitive movements, and lifting heavy loads.

Conclusion

The prevalence of WMSDs among farmers in Southeast Asia is considerably high. Effective intervention is essential for reducing the prevalence and protecting workers' health and well-being.

Prevalence, Patterns, and Risk Factors of Work-Related Musculoskeletal Diseases Among Teachers in the Eastern Province, Saudi Arabia: A Community-Based Retrospective Cross-Sectional Survey

Background and objective Work-related musculoskeletal diseases (WMSDs) are one of the most common occupational health concerns among teachers. They refer to a variety of degenerative and inflammatory disorders that can be triggered by the work environment of the people affected. Teachers' health is substantially significant as it impacts their productivity at work. The aim of this study was to determine the prevalence, patterns, implications, and risk factors of WMSDs among teachers in the Eastern Province of Saudi Arabia. Methods This study involved a survey based on a cross-sectional questionnaire that was distributed to 404 random school teachers located in the Eastern province of Saudi Arabia. Information such as sociodemographic characteristics, workplace characteristics, characteristics of WMSDs experienced, associated factors, and impact of the symptoms experienced was collected. Questions related to symptoms were obtained from the Nordic Musculoskeletal Questionnaire and Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ). The collected data were then analyzed using the SPSS Statistics version 23.0 (IBM Corp., Armonk, NY). Results Among the participants, back pain, shoulder pain, and knee pain were the most reported symptoms of WMSDs in the past 12 months, while elbow pain was the least experienced; 41.1% had pain, discomfort, or numbness that prevented them from performing regular daily activities. The regression analysis revealed a relationship between moderate to severe pain and a pain duration of more than 12 months (p=0.001). Additionally, those who were able to perform lighter work and were not having depression had a low probability of pain persistence and were able to carry out their usual work while experiencing pain (p=0.002). Conclusions In the Eastern province of Saudi Arabia, WMSDs were commonly reported by school teachers. The prevalence of WMSDs among teachers was 41.1%. The pain was described as disabling and causing a negative impact on performance. The most common locations of symptoms were the back, shoulder, and knees. Risk factors for severe pain were female gender, sleeping for six to seven hours, and pain located in the neck shoulder, elbow, hand, thigh/hips, back, knees, and ankles. Furthermore, severe pain was associated with pain duration of more than 12 months, affecting sleep, causing anxiety, and mild depression. The impact of severe pain seriously affected the daily activities of teachers.

Evaluation of working conditions, work postures, musculoskeletal disorders and low back pain among sugar production workers

BACKGROUND: It is generally agreed that musculoskeletal disorders (MSDs) are a severe health concern, particularly for agricultural laborers. OBJECTIVES: The study aimed to identify risk factors and work-related disorders among agricultural workers at Amirkabir agro-industry company in Iran. METHOD: A total of 158 workers, of which 66 were manual harvesting workers (four postures), 40 were fertilizer transportation workers (three postures), and 52 were spraying workers (one posture), were included in the study. The research used questionnaires to collect data, and the postures were analyzed using 3DSSPP software. Related risk factors such as age, body mass index, work experience, working hours, and sports activity were analyzed. RESULTS: The incidence rate of lower back pain (94%), knee pain (82%), neck pain (69%), upper-back (63%), and shoulder (63%) were calculated. The logistic regression revealed that working hours and sports activities are significantly correlated to the wrist/hand and neck MSD with 5.62 and 6.38 times more likely among manual harvesting workers. The 3DSSPP software estimated that the lower back pain, especially in the first posture, for manure transportation workers was very high. Maximum L5-S1 compression, shear, and moment forces in the first posture among manure transportation workers were 7113 N and 472 N, -381 N-m, respectively. CONCLUSION: The 3DSSPP results also illustrated that compression, shear, and moment forces exceeded the NIOSH limit for the other postures. After interventions, compression, shear, and moment forces among all farm workers decreased. These findings emphasize that farm workers need to be under surveillance continuously at their workstations where interventions and improvement in specific tasks are required.

Musculoskeletal Pain Among School Teachers in Qassim, Saudi Arabia: Prevalence, Pattern, and Its Risk Factors

Introduction 

Work-related musculoskeletal disorders (WMSD) are defined as conditions that the environment contributes significantly to / worsens due to work conditions. WMSD comes second in the source of disability in both developed and developing countries. The aim of this study is to measure the prevalence, patterns, and risk factors of musculoskeletal pain disorders among teachers in the Qassim region, Saudi Arabia.

Methods

A cross-sectional study was conducted among school teachers in the Qassim region, Saudi Arabia. A validated online Arabic questionnaire was distributed among teachers living in the Qassim region through multiple social networking applications like Facebook, WhatsApp, and Telegram. The questionnaire consisted of Socio-demographic characteristics, the Nordic Musculoskeletal Questionnaire, and a modified version of the Örebro Musculoskeletal Pain Screening questionnaire.

Results

A total of 503 school teachers were recruited. The proportion of musculoskeletal pain was 91%, and the most common site of pain was back (74.4%), followed by the shoulder (57.5%) and leg (51.5%). The proportion of disabling pain was (80.1%) while the rest was non-disabling pain (19.9%). In the multiple regression model, the predictors of increased disabling pain were back pain, leg pain, neck pain, and those with 51-70 kg weight. In comparison, the predictors of decreased disabling pain were having more than 7 hours of sleep and those with 20-30 classes per week.

Conclusion

Musculoskeletal pain disorders were widely prevalent among school teachers in the Qassim region, Saudi Arabia. Most teachers considered pain as disabling, which negatively affected their attendance. The back, shoulder, and neck were the most painful sites associated with disabling pain.
