Abstract
OBJECTIVE To estimate the prevalence of work-related musculoskeletal disorders and their association with physical activity among schoolteachers in the United Arab Emirates. METHODS This observational cross-sectional study involved 209 schoolteachers (aged 20-60) with a minimum of two years of experience. Data, including demographics (gender, age), Nordic Musculoskeletal Questionnaire (NMQ) for WMSD prevalence and pain sites, and Global Physical Activity Questionnaire (GPAQ) for physical activity levels, were collected. Six schools were visited for data collection, with consent from school heads and participants. Schedules were tailored to participant availability, allowing up to three attempts for participation. Non-respondents were identified after three unsuccessful attempts. RESULTS Of the total 206 participants, 149 were female, while the remaining 57 were male. Age distribution analysis revealed that 18% of individuals were within the 20 to 30 years range, 26.2% fell within the 30 to 40 years, and 36.9% had 40 to 50 years age brackets. The responses were obtained in Arabic (90%) and English (10%). The study identified a high prevalence (71.4%) of work-related musculoskeletal disorders (WMSD) in UAE schoolteachers, with neck pain being the most common (74.3%). Major risk factors included age, workload, and low physical activity. The data was normally distributed, and Pearson's Correlation test revealed weak positive correlation (r: 0.14), but statistically significant (p value = 0.04) between WMSD and PA, indicating that it was a contributing factor but other factors beyond PA influenced WMSD prevalence in this cohort. The findings of the study are based on certain limitations such as cross-sectional design and convenient sampling which could have potential selection bias and affect generalizability of the results. CONCLUSION Findings suggest the need to promote physical activity and reduce workload for teachers, considering their age and gender. Additionally, there is a need to raise awareness regarding ergonomics and the importance of taking short breaks for stretching or physical movement to enhance the overall well-being of schoolteachers in the UAE and similar contexts. Diverse prevalence rates across different body areas underscore the necessity for individualized treatments.

Abstract
BACKGROUND Work-related musculoskeletal disorders most commonly contribute to years lived with disability among workers. Heavy physical work, static work posture, awkward posture, force exertion, lifting and repetitive movements increase the risk of developing work-related musculoskeletal disorders. OBJECTIVES The aim of the study was to determine the prevalence of work-related musculoskeletal disorders and associated factors among non-academic workers at the University of Zimbabwe Faculty of Medicine and Health Sciences. Non-academic workers included security personnel, catering staff, drivers, library staff, clerical staff, technicians and janitorial staff. METHODS AND MATERIALS The study used a cross-sectional analytical design. One hundred and eight non-academic workers at the University of Zimbabwe Faculty of Medicine and Health Sciences were sampled through proportional stratified sampling in January 2021. An adapted Nordic Musculoskeletal Questionnaire capturing socio-demographics and ergonomic risk factors was used to gather data. SPSS v24 was used for data analysis including frequencies, tests of association and multivariate logistic regression. RESULTS One hundred non-academic workers from the University of Zimbabwe Faculty of Medicine and Health Sciences responded. The 3-month and 12-month prevalences of work-related musculoskeletal disorders were highest in the lower back (n = 72, 72% and n = 75, 75%) and wrists/hands (n = 60, 60% and n = 69, 69%) respectively. Sociodemographic factors such as age (p = 0.002), gender (p < 0.001), educational level (p = 0.008) and worker category (p < 0.001) were associated with increased work-related musculoskeletal disorders, while work experience (p = 0.002) was associated with a decreased prevalence of back pain and discomfort. Females (AOR = 55.90; 95% CI [3.84, 814.54]), security personnel (AOR = 39.53, 95% CI [1.57, 996.00]), catering staff (AOR = 91.3295% CI [2.24, 3724.78]) and those who attained bachelor's degrees (AOR = 73.25, 95% CI [1.46, 3682.39]), higher national diplomas (AOR = 93.49, 95% CI [1.28, 6848.04]) and national diplomas (AOR = 52.22; 95% CI [1.09, 2510.73]) had higher odds of experiencing WMSDs. Increased working experience was protective against experiencing lower back pain (AOR = 0.84; 95% CI [0.74, 0.95]). DISCUSSION AND CONCLUSION The prevalence of work-related musculoskeletal disorders was high among the participants. This was influenced by the nature of work as well as cultural factors. RECOMMENDATIONS Occupational therapists and physiotherapists need to design focused ameliorative and health promotive interventions targeting at-risk populations in universities. Employers should consider developing wellness programs for workers and promoting healthy working environments.

Abstract
Data on the prevalence and risk factors of low back pain (LBP) in Malaysia remain unclear as they are currently limited to specific settings and occupational groups. Therefore, this study aims to determine the prevalence and risk factors of low back pain in Malaysia. In this scoping review, we had systematically searched PubMed, Scopus, ScienceDirect and Google Scholar from January 2016 to April 2020. In addition, we had included cross-sectional studies on LBP in Malaysia. Studies without data on the prevalence and risk factors were excluded. The settings, population, design, sample size, evaluation methods, prevalence and risk factors of the studies were summarised. The literature search identified 435 potentially eligible studies; of these, 21 had met the inclusion criteria. The prevalence of LBP in Malaysia among various types of the population had ranged from 12.4% to 84.6%. Among the various types of occupation, the prevalence of LBP was the highest among nurses (67.9%), followed by drivers (65.7%). In addition, age, gender, body mass index (BMI), lifting heavy objects, working posture, lifestyle, working hours and mental health were identified as the risk factors of LBP in Malaysia. The current evidence suggests that LBP is a serious health problem among several occupational groups in Malaysia. Therefore, it is crucial to implement the correct interventions for the prevention of LBP among these groups.

Abstract
Introduction Musculoskeletal disorders (MSDs) represent an important threat to public health in both developed and developing countries, and are present in many occupational sectors including education. Regular practice of physical activity (PA) is known elicit preventive effects on the occurrence of MSDs. Objective This study aimed at determining the prevalence of MSDs and the preventive impact of PA on their occurrence among secondary school teachers. Participants and Methods A cross-sectional study was conducted among 179 teachers in five government secondary schools in Douala, Cameroon. The Nordic and Ricci-Gagnon questionnaires were used to determine MSDs and to assess the level of PA, respectively. Results The 12-month and 7-day prevalence of MSD (PMSD-12m and PMSD-7d) were 84.3% and 69.3%, respectively. The most affected body regions by MSDs were neck (PMSD-12m = 54.2%, PMSD-7d = 33.5%), lower back (PMSD-12m = 43%, PMSD-7d = 33%), and shoulders (PMSD-12m = 35%, PMSD-7d = 22.9%). Compared to female, males were protected against MSDs during the last 12 months (OR = 0.37; 95% CI 0.16-0.93; p = 0.04). The risk of MSDs during the last seven days was higher in teachers aged 30-40 years (OR = 2.86; 95% CI 1.14-7.14; p = 0.02) and 40-50 years (OR = 4.28; 95% CI 1.49-16.29; p = 0.008) than those under 30 years. This risk was tripled in inactive teachers (OR = 3.07; 95% CI 1.40-6.78; p = 0.005), compared to their active counterparts. Conclusion MSDs are prevalent among secondary school teachers and associated with aging, gender, and lower level of PA.

Abstract
BACKGROUND School teachers constitute an occupational group which reported a high prevalence of work-related musculoskeletal disorders (WRMSDs). Different individual, occupational and psychosocial factors have been identified to influence the complex process of WRMSDs. WRMSDs represent an important and costly occupational health problem being responsible for a poor quality of life (QOL) of teachers. This study aimed to determine the prevalence, the risk factors, and the impact of WRMSDs on the QOL of teachers. METHODS 310 full-time teachers from 15 public schools were surveyed using an interview questionnaire about their sociodemographic and occupational characteristics, the Nordic Musculoskeletal Questionnaire and the SF-36 Health Survey (SF-36). RESULTS Self-reported prevalence of WRMSDs at any body part over the past 12 months among teachers was 66.77%. Neck pain (56.1%) was the most prevalent WRMSD followed by shoulders (53.2%), low back (53.2%) and knees (50.6%) pain. Female gender, body mass index, the number of students per classroom, the number of classes per week, different adapted awkward postures and the lack of enough supervisor's psychological support at work were among the risk factors positively associated with WRMSDs. WRMSDs had a negative impact on the physical and mental QOL of teachers with WRMSDs as reflected by their lower scores on all scales of the SF-36 compared to their counterparts without WRMSDs (p ˂ 0.05). CONCLUSION WRMSDs were a highly prevalent problem among teachers in Cairo, Egypt and negatively influencing their physical and mental QOL. Different individual, occupational and psychosocial factors had been shown to be significant predictors for the occurrence of WRMSDs reflecting their complex nature and multifactorial etiology.

Abstract
Objectives. This study aimed to explore the work productivity loss (WPL) due to musculoskeletal symptoms (MS) and its explanatory psychosocial, ergonomic and personal factors in Tunisian shoe and leather industry workers. Methods. We conducted a cross-sectional survey among 337 workers. We evaluated WPL using the work productivity and activity impairment questionnaire. We used the Nordic questionnaire to assess the MS prevalence, the job content questionnaire of Karasek to examine the psychosocial work environment and the quick exposure check (QEC) tool to estimate the ergonomic exposure levels. Results. The mean WPL was 44.9 ± 33%. In the multiple linear regression model, WPL was positively correlated with a history of MS, professional seniority, a rhythm perceived as restrictive, low social support and decision latitude, the number of symptomatic sites and the QEC strain level of the back. Conclusion. There was a decline in work productivity due to MS that results from a combination of personal, psychosocial and biomechanical factors. Once addressed, both work productivity and workers' well-being should be restored.

Abstract
BACKGROUND: Typically, bricklayers in developing countries’ contexts manually lay bricks, concrete blocks and other similar materials to construct walls and buildings which make them susceptible to work-related musculoskeletal disorders (WRMSDs). The burden of WRMSDs among this high-risk group seems has not been well documented. OBJECTIVES: This study examined the prevalence of WRMSDs among bricklayers in Nigeria. METHODS: A cross-sectional survey of 118 consenting bricklayers from a Nigerian setting was carried out. The standardized Nordic musculoskeletal disorder questionnaire and a proforma were used to profile the prevalence of WRMSDs and socio-demographic information of the respondents. Data was analyzed using descriptive and inferential statistics. Alpha level was set at p < 0.05. RESULTS: The 12-months and 7-days prevalence of WRMSDs were 87.3% and 67.4%. Shoulder (61.0%) and the low-back (59.3%) were the two most affected anatomical sites based on 12-month prevalence. WRMSDs affecting the knees (6.8%) was the most disabling in carrying normal work routines. Working for less than 10 years was significantly associated with high prevalence of WRMSDs in the shoulder (odd ratio (OR) = 0.27, 95% confidence interval (CI) = 0.09 to 0.87) and wrist region (OR = 0.24, 95% CI 0.08 to 0.73). Having neck pain led to higher odds (OR = 0.29, 95% CI 0.13 to 0.68) of taking a break from work among the bricklayers. CONCLUSIONS: WRMSDs were high among Nigerian bricklayers. Years of work experience was associated with high prevalence of WRMSDs in the shoulder and wrist. In addition, taking work breaks was associated with neck pain.

Abstract
Background Work-related upper extremity disorders (WRUEDs) are aches, pains, tension, and discomfort in the neck, shoulders, arms, wrists, hands, and fingers. The situation is escalating in educational sectors due to a lousy working environment intertwined with extracurricular deeds. However, empirical evidence focusing on academicians in higher education society is negligible. The purpose of this study is to examine the prevalence and risk factors of WRUEDs among university teaching staff in Ethiopia. Materials and Methods We conducted a cross-sectional study design from March to April 2021. A sample of 607 academicians were recruited using a stratified sampling technique, and a self-administered structured Nordic Musculoskeletal questionnaire was used to assess upper extremity disorders during the past 12 months. The collected data were entered into EpiData version 4.6 and analyzed using STATA version 14 software. The association between dependent and independent variables was computed with a binary logistic regression. The association was ascertained using an adjusted odds ratio (AOR) with a 95% confidence interval (CI) at a p value of <0.05. Results A total of 607 participants correctly completed the questionnaire (response rate of 95.44%). Age ranges from 21 to 70 with a mean of 32.39 (SD ± 6.80)) years, and the majority (76.28%) of them were males. The prevalence of WRUED during the last 12 months was 59.14% [95% CI (55.1, 63.1)]. There is no significant difference in prevalence between males and females (45.14% versus 14%), respectively; χ2 = 0.001; p=0.974. Working more than 8 hours per day [AOR: 2.37; 95% CI (1.40, 4.00)], not performing physical exercise [AOR: 2.34; 95% CI (1.6, 3.45)], and job dissatisfaction [AOR: 2.50; 95% CI (1.69, 3.68)] were factors significantly increased the risk of experiencing WRUEDs. Conclusion This study divulged upper extremity disorder among university teaching staff is pervasive, with more than three-fifth of the academicians were suffering from the condition, and it also indicates that males experienced higher proportions of pain than females. The manifestation of upper extremity disorder was affected by working hours per day, physical activity, and job satisfaction. Optimizing working hours, having a group regular exercise, and proper management of workplace conditions related to job satisfaction are recommended to lessen the condition.

Abstract
Occupational traffic accidents are a leading cause of injuries or deaths among workers. Teachers in Spain are especially concerned about the problem of commuting due to their particular labor conditions. Multiple work-related factors are associated with the risk and severity of occupational traffic-related motor vehicle crashes. The objective of this research is to analyze the influence of the variables associated with the severity of occupational traffic accidents among teachers in Spain. A logistic regression model was used for the current study. The odds ratio (OR) and confidence interval (CI) were calculated for the injured worker on a sample of 20,190 occupational traffic accidents suffered by teachers. The results showed that women, Spanish nationality, younger than 55 years, and those driving a car were more likely to suffer a light crash. In contrast, men, foreign nationalities, older than 55 years, and those riding a motorbike were more likely to suffer a serious crash. Based on these findings, motor vehicle safety training could be designed and adapted to the riskiest profiles. Additionally, effective mobility plans for commuting could help reduce work-related traffic accidents.

Abstract
Academicians across the globe due to Covid 19 shifted to online teaching as a mainstream method by replacing the chalk and talk method. The main objective of this study is to find the impact of different sizes of digital boards used for online teaching on muscle activity and muscle fatigue, and then results are compared with conventional writing. Initially, a questionnaire survey is conducted among 100 college professors about the issue they faced while using online teaching methods. Experimental analysis are then conducted using electromyography sensor (sEMG) among ten college professors and their muscle activity on the dominant hand and neck while writing on two commercially available digital boards namely Type 1 (small writing area) and Type 2 (large writing area). Four muscles namely Flexor carpi radialis, Extensor carpi radialis, Biceps brachii, and Sternocleidomastoid (SCM) are chosen for the study. The results are then compared with muscle activity while writing on conventional A4 sheets. Normalized root mean square (RMS) is used to assess the muscle activity and the trend line of MPF value is utilized to assess the muscle fatigue. The results show that SCM muscle has more muscle activation compared to other selected muscles followed by flexor carpi radialis. Subjective analysis is carried out using the Borg scale, which has reported that Type 2 digital board having larger working area was preferred by the participants as it reduces muscle fatigue.

Abstract
The aim of this study was to assess the epidemiology of musculoskeletal disorders (MSDs) among the teaching staff of the University of Douala and determine their association with physical activity (PA) practice. The Nordic questionnaire was used to assess MSDs. Ricci-Gagnon questionnaire was used to determine the level of PA. We recruited 104 participants mean-aged 42 ± 8 years, 80% male. Previous 7 days and 12 months prevalence were 56.7% and 80.8%, respectively. The most affected body regions were neck, shoulders and lower back. No significant association was found between MSDs and PA. Celibacy was significantly associated with previous 7-days MSDs (p = 0.048) while age ≥ 45 years and job seniority ≥ 10 years were significantly associated with a reduced risk of previous 12-months MSDs (p = 0.039 and p = 0.016, respectively). The prevalence of MSDs among university of Douala teaching staff showed no significant effect with the practice of PA.

Abstract
Introduction: Teachers have been reported to be a labor group with high rates of musculoskeletal disorders (MSDs), stress, and strong deterioration of quality of life (QoL). However, little information exists about the association between MSD, QoL, and body composition in rural and urban teachers. Objective: The aim was to study the association of MSD with QoL perception and body composition of urban and rural teachers. Participants and Methods: Participants are comprised a representative sample of urban and rural public schoolteachers from the Valparaiso Region, Chile. MSDs were evaluated with the Standardized Nordic Questionnaire for Musculoskeletal Symptoms validated for the Chilean population. QoL perception was evaluated with the 36-Item Short-Form Survey (SF-36). Body composition was measured via bioimpedance. A logistic regression model was used to evaluate the association between MSD, QoL, and body composition, adjusted for age and gender. Results: A total of 88.9% (urban 90%; rural 87%) of teachers felt pain in some body area, 71.2% of them with limitations; 39% of teachers presented body fat obesity, with the highest rate in rural women. The body area with the greatest MSD prevalence was the neck and shoulders (68.6%). Significant differences were observed between teachers with >p75 of MSD (over six pain regions) and those with ≤p75 (six or fewer painful regions; p < 0.05) on six QoL scales and on physical health components (PCSs) and mental health (MCS) in urban teachers. However, rural teachers presented no differences. The association between teachers with >p75 MSD and low QoL perception was significant (p < 0.05) in PCS and MCS. Furthermore, the regression model presents a significant association between rural areas and low PCS perception. Conclusions: Urban and rural teachers present high rates of MSD and obesity. Teachers with higher rates of MSD have their mental and physical QoL affected, making workplace intervention in MSD necessary to prevent teacher health deterioration.

Abstract
BACKGROUND Despite the increasing emergence of modern facilities, the ancient practice of writing on a teaching board is still common in the teaching profession. Ergonomic guidelines of this practice are required for the prevention of work-related neck musculoskeletal disorders inherent of teachers. OBJECTIVE This study investigated the effects of varying teaching board heights on the activities of the neck muscles. METHODS Thirty participants (15 males and 15 females) participated in this experimental study. Each performed writing tasks on a teaching board set at five different heights derived from their standing height (SH) [(D 10 = SH minus 10% of SH; Norm H = SH; Sum 10 = SH plus 10% of SH; Sum 20 = SH plus 20% of SH; Sum 25 = SH plus 25% of SH)]. Electromyographic (EMG) activities of both components of the sternocleidomastoid and upper trapezius muscles were measured during each task. Asymmetry ratio of right and left muscle components were determined. Data were analyzed with one-way ANOVA. RESULTS EMG activities of the four muscles as well as their asymmetry ratios significantly (p< 0.01) increased with increasing board heights. CONCLUSION Teaching board-related tasks have increased possibilities of inducing neck disorders when performed beyond Norm H vertical heights.
