The health and quality of life of dental workers in jordan during COVID-19: A cross-sectional study.

Dental team members are susceptible to high mental and physical stress levels, which could have increased during the Coronavirus disease 2019 (COVID-19). This study aimed to evaluate Jordanian dental workers' health-related quality of life (HRQoL) and determine its predictors during the COVID-19 Pandemic. This was a cross-sectional survey study conducted on dental team members, namely; Dentists, dental Assistants, and Dental Technicians. The survey questionnaire was composed of questions related to stress during COVID-19, a short-form survey of 12 items (SF-12), a Depression, Anxiety, and Stress scale (DASS-21), and a Nordic musculoskeletal disorder questionnaire (NMQ). Descriptive analyses were used to describe the main outcome measures, and multiple variable regression analysis was conducted to identify the quality of life predictors. Participants' HRQoL measured by SF-12 showed a mean±SD score of 67.1±17.19 for the physical component and 54.51±20.27 for the mental component. The Nordic scale showed symptoms of lower back pain as 63.9% over 12 months, 32% over 12 months' functional limitation symptoms, and 45% in 7 days The regression model was found strong for our study with 53.8% variations (r2 = 0.538, F = 43.739, P < 0.001) in health-related quality of life. Our study concluded that the level of HRQoL among Jordanian dental specialists during COVID-19 was observed to impact levels of physical and mental well-being which negatively influence the quality of life. Predictive factors like depression, stress, anxiety, musculoskeletal health, and individual everyday quality of life significantly affect the HRQoL of dental specialists.

Fizyoterapi Birinci Sınıf Öğrencilerinin Egzersiz Algısı ile Muskuloskeletal Ağrı ve Akıllı Telefon Bağımlılık Düzeyi Arasındaki İlişki

Purpose: We think that possible inactivity and a high risk of smartphone addiction may increase the potential musculoskeletal disorders in physiotherapy and rehabilitation students before beginning their professional lives. To draw attention to this issue, we aimed to investigate the relationship between exercise perception, musculoskeletal pain, and smartphone addiction. Material and Methods: Demographic data form, Exercise Benefit/Barrier Scale (EBS), Cornell Musculoskeletal Disorder Questionnaire (CMDQ), and Smartphone Addiction Scale (SAS) were filled out online by 45 volunteer students from the Physiotherapy and Rehabilitation Department of Kırklareli University's Faculty of Health Sciences. Results: It was found that those who regularly exercised had lower EBS (p=0.031), exercise benefit (p=0. 029) and exercise barrier (p=0.251) scores, higher right forearm pain scores (p=0.035), higher median values for the CMDQ total score (p=0.052) and lower median SAS total scores (p=0.101) than those who did not. Conclusion: There was no statistically significant correlation between exercise perception, musculoskeletal pain, and smartphone addiction. However, it has been found that students who have the habit of exercising regularly have a lower level of exercise perception, a higher level of musculoskeletal pain, especially a higher level of forearm pain, and a lower risk of smartphone addiction.

Analysis of work-related musculoskeletal disorders among automobile manufacturing logistics workers in Guangzhou

Objective: To investigate the occurrence of work-related musculoskeletal disorders (WMSDs) in logistics workers of automobile manufacturing enterprises in Guangzhou, and explore their potential categories and influencing factors, so as to provide basis for the prevention and control of WMSDs in logistics workers of automobile manufacturing enterprises. Methods: From April to May 2020, a convenient sampling method was adopted to select 1442 logistics workers in 2 automobile manufacturing enterprises in Guangzhou as the research objects. The incidence of WMSDs among them was investigated by using the Nordic Musculoskeletal Disorders Questionnaire, and the incidence pattern of WMSDs among the subjects was analyzed by the method of potential category analysis. Chi-square test and multiple logistic regression model were used to analyze the influencing factors of the disease. Results: The total prevalence of WMSDs was 42.9% (619/1442). The three parts with high prevalence of WMSDs were neck (23.5%, 339/1442), shoulder (21.3%, 307/1442) and lower back (19.1%, 275/1442). 69.0% (427/619) of the patients showed simultaneous disease in two or more sites. The subjects were divided into four latent groups by the analysis of latent categories: the group with multiple body parts (4.51%), the group with very low or no disease (70.39%), the group with shoulder and neck and upper back (11.37%), and the group with limbs and lower back (13.73%). Multivariate logistic regression showed that compared with the "very low or no disease group", the risk factors of multiple body parts of automotive logistics workers suffering from WMSDs mainly included: Working posture uncomfortable (OR=3.10, 95%CI: 1.44~6.70, P=0.004), often bend and turn (OR=2.36, 95%CI: 1.05~5.29, P=0.037), bend your knees homework for a long time (OR=2.29, 95%CI: 1.17~4.47, P=0.015) ; Working posture uncomfortable (OR=2.26, 95%CI: 1.51~3.38, P<0.001), bending the neck (OR=1.68, 95%CI: 1.03~2.74, P=0.036), neck minister time keep the same position (OR=1.81, 95%CI: 1.22~2.67, P= 0.003) It is a risk factor for shoulder, neck and upper back WMSDs; Risk factors for limb-lower back WMSDs include: Length > 10 years (OR=2.16, 95%CI: 1.24~3.78, P<0.001), the working position uncomfortable (OR=2.38, 95%CI: 1.63~3.48, P<0.001), bending the neck (OR=1.66, 95%CI: 1.03~2.68, P=0.039) . Conclusion: The prevalence rate of WMSDs among logistics workers in automobile manufacturing enterprises is high, which has obvious characteristics of classification and comorbis, and is closely related to individual characteristics such as sufficient rest time and working posture of workers.

Musculoskeletal Disorders and Their Impact on Job Performance Among School Teachers in Buraydah City.

Musculoskeletal disorders (MSD) pose a significant challenge to the well-being and productivity of individuals and various occupational groups, including teachers. Among teachers, the prevalence of MSD has raised concerns globally, impacting their daily activities and overall quality of life. Buraidah and Saudi Arabia, like many other regions, face the implications of this issue. This study aimed to explore the prevalence and associated risk factors of MSD among teachers in Buraydah, providing valuable insights into the extent of the problem and potential areas for intervention. An analytic cross-sectional study was conducted for three months, from April 1 to June 30, 2023, using the Arabic version of the standardized Nordic Musculoskeletal Disorder Questionnaire. This study was conducted in all schools in Buraydah City, Saudi Arabia. The study population was all schoolteachers (including principals, vice principals, etc.) in Buraydah City. The study analyzed responses from 648 teachers and 139 school workers using statistical tests, including chi-square tests and logistic regression models. The results indicated a notable prevalence of MSDamong teachers, with a significant association found between age, gender, and major depressive disorder (MDD) and MSD. The study reveals that females are at higher risk of MSDcompared to males, emphasizing the need for gender-specific interventions. Moreover, the presence of MDD is identified as a significant contributor to MSDamong teachers. However, certain demographic and lifestyle factors, such as marital status, level of school, smoking habits, and fixed rest times, do not show significant associations with MSD. Although age and years of experience are correlated, only age is found to significantly contribute to MSD. Regular exercise and BMI also do not emerge as significant contributors, although a lack of exercise shows a marginal impact. This study's findings have implications for educational institutions and policymakers, highlighting the need for tailored interventions to address MSDamong teachers. It underscores the importance of ergonomic interventions, gender-sensitive approaches, and mental health support.

Negative effects of the COVID-19 pandemic on the musculoskeletal system and depression in healthcare professionals.

During the COVID-19 pandemic, it is thought that healthcare workers are most exposed to musculoskeletal disorders. However, there are limited studies in the literature examining the musculoskeletal disorders among healthcare workers during the COVID-19 pandemic. The aim of this study was to examine musculoskeletal problems and psychological disorders in healthcare personnel working at Dicle University Faculty of Medicine and Research Hospitals during the COVID-19 pandemic and to come up with solutions for rehabilitation. The Cornell Musculoskeletal Disorder Questionnaire (CMDQ) was used to assess musculoskeletal problems in the past week. Additionally, Beck depression inventory (BDI) was used to evaluate the psychological state of the participants. Questions on demographic characteristics, habits, the presence and localisation of musculoskeletal system (MSS) diseases, severity and duration of pain, chronic diseases, trauma history and working conditions were included in the questionnaire prepared by the researchers. The study included 74 nurses, 42 residents, 26 specialists, 24 technicians, 16 dentists, 12 physiotherapists, and 26 other allied health personnel. Dentists had the highest total CMDQ score (160.73) whereas resident doctors had the lowest total CMDQ score (98.33). Low back, neck and back pain were the most common MSS problems. BDI was highest in nurses and 70.27% of the nurses were women. The total workplace ergonomics score was found to be 25.91%, and the visual analogue scale (VAS) was highest in nurses (6.72). While MSS pain is concentrated on the waist, neck and back regions in all healthcare workers. We concluded that the uncertainty associated with the pandemic, delay in preventive measures such as vaccination and medication, rapid and strong transmission of the disease and increasing number of deaths have led to an increase in stress, depression and burnout among healthcare workers.

Epidemiological study of work-related musculoskeletal disorders and related risk factors among automobile maintenance workers.

The automotive industry is labor-intensive, and workers are involved in highly repetitive tasks, long hours, and medium to low workloads, resulting in work-related musculoskeletal disorders (WMSDs), which have become a major health concern for workers in this industry. China is a major automotive country with tens of thousands of auto repair workers, but their conditions of WMSDs have been poorly reported. This work aimed to analyze the current prevalence of WMSDs and their associated risk factors among automobile maintenance workers. A total of 539 respondents from 50 automotive repair and maintenance companies in China were selected to investigate the prevalence of WMSDs via the modified Nordic Musculoskeletal Disorders Questionnaire. Chi-square test and logistic regression models were applied to analyze their associated risk factors. The total prevalence of WMSDs among 539 workers was 32.8%. The top three body parts for prevalence were the lower back (17.1%), neck (16.3%), and shoulders (14.5%). The highest prevalence of WMSDs was found in the neck (23.6%) and lower back (14.3%) for sheet metal workers and mechanics, respectively, whereas painters had the highest prevalence of WMSDs in the lower back and feet (both at 15.4%). Logistic regression analysis showed that females were at higher risk of WMSDs than males (OR 5.027, [95% CI] [1.278-19.772], p < 0.05). Workers subjected to uncomfortable positions were at increased risk of WMSDs (OR 1.79, [95% CI] [1.333-2.410], p < 0.01). The prevalence of WMSDs is high among automotive maintenance workers, with the highest prevalence in the lower back (17.1%). Uncomfortable working postures and frequent repetitive movements with lower limbs and ankles at work may be important risk factors.

Work-related musculoskeletal disorders in vulnerable populations: what are the most common body parts affected?

Studies investigating vulnerable populations have shown that work-related musculoskeletal disorders have a negative impact on quality of life. However, no study has examined the body regions commonly affected by work-related musculoskeletal disorders in vulnerable populations. To describe the body regions commonly affected by work-related musculoskeletal disorders in vulnerable populations. Cross-sectional study. We used the ABEP questionnaire, the World Health Organization Quality of Life, the Nordic Musculoskeletal Disorders Questionnaire, the Perceived Stress Scale, and a self-report questionnaire to determine morning-evening in human circadian rhythms (chronotype assessment). To reduce the possibility of information bias, we provided prior training in the use of the instruments and created an electronic database that was filled out in duplicate (in cases of disagreement, a third researcher was consulted). We tested the normality of the data using the Shapiro-Wilk test. The sample consisted of 132 participants, but there was a sample loss of 41.6% (final sample n = 77). We observed the predominance of those who worked from 6 to 8h/day, rest of 1h during the working day, from 1 to 10years of service and only 1 employment relationship. Regarding the quality of life, we observed a worse result in the domain related to the environment, as well as a stress level of 15.43 (± 7.52) with a maximum of 30. Finally, we observed the presence of pain self-reported by the artisanal fishermen in several regions of the body, lumbar being the most mentioned. The neck, shoulders, arms, elbows, forearms, wrists, back, lumbar spine, and lower limbs are the most common parts of the body affected by work-related musculoskeletal disorders in artisanal fishermen.

Self-reported musculoskeletal disorders questionnaire for agriculturists: An online self-assessment tool development.

The musculoskeletal disorders (MSDs) severity and frequency questionnaire (MSFQ) has been used with agriculturists. Although it frequently appears in the literature, it does not periodically reflect the levels of MSDs. This study aimed to develop a MSDs assessment tool for agriculturists via an online database. The four hospitals that were assigned to the development and tryout group received a random selection of participants from 33 health promoting hospitals. In the development phase, 55 agriculturists (from two hospitals) completed the structured interview questionnaire. The MSFQ document for the analysis of MSDs symptoms among agriculturists was concentrated on the frequency and severity of symptoms. The online MSFQ was checked by using intraclass correlation coefficients (ICC) in a one-way random-effects model. In the tryout phase, a group of 44 agriculturists (from another two hospitals) completed a similar online MSFQ. Cronbach's alpha was used to test the reliability of the online self-reported MSDs questionnaires. A Likert rating scale, used to measure the satisfaction of users, was divided into three categories: information, program design, and benefits. The development phase showed an ICC = 0.99 with a 95% CI = 0.98-0.99. More than 65 percent of agriculturists were female, aged from 41-50 years old. A large number of them were engaged in self-cultivation. Their main crops were rice and cassava. In total, 50% reported that they had experienced mild MSDs levels. The shoulder, knee-calf, and hip-thigh areas were the top three parts of the body where agriculturists had experienced MSDs from cultivation. Excellent reliability of online MSFQ was found after the tryout. The agriculturists were very satisfied overall (information, program design, and benefits). Developments to the MSFQ and online administration did not diminish its reliability for obtaining information about the level of MSDs of agriculturists' musculoskeletal symptoms. This self-reported MSDs questionnaire was appropriate to be used among agriculturists.

Multi-Site Musculoskeletal Symptoms in the Electronics Manufacturing Industry in China: A Cross-Sectional Study.

Background: With the development of the electronics manufacturing industry, the demand for human resources has increased, which has also led to the frequent occurrence of multi-site work-related musculoskeletal disorders. Method: The participants (n = 7307) were recruited from 30 enterprises in China in 2018. The prevalence of musculoskeletal disorders was estimated using a modified Chinese version of the Musculoskeletal Disorders Questionnaire. The multivariate logistic regression model was applied to evaluate the effects of risk factors on multi-site musculoskeletal symptoms. Additionally, the log-binomial model was established to examine the correlation between the various sites of musculoskeletal symptoms in the body. Results: The 12-month prevalence of musculoskeletal symptoms among participants was 40.6%. The proportion of musculoskeletal symptoms involving single-site and 2/>2 body sites were 11.6% and 29.0%, respectively. The results of logistic regression showed that female adults who smoked, had >5-year job tenure, and always stood or sat for long period at work had a higher risk in 2/>2 body sites of musculoskeletal symptoms (p < 0.05). However, physical exercise during leisure time and “Squatting or kneeling for long period at work” were more frequently protective factors. Furthermore, the log-binomial model indicated that the neck and shoulder were significantly related to each other (Prevalence Ratio, PR: 5.511 and 7.017). Conclusions: Several demographic characteristics and work-related factors were associated with multi-site musculoskeletal symptoms in the electronics manufacturing industry in China. Improving the levels of physical exercise and reducing posture problems and force loads may help to promote the health of workers.

Prevalence and pattern of work-related musculoskeletal disorders among Nigerian bricklayers.

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. This study examined the prevalence of WRMSDs among bricklayers in Nigeria. 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. 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. 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.

Occurrence pattern of musculoskeletal disorders and its influencing factors among manufacturing workers

To explore the occurrence pattern and its influencing factors of multi-site work-related musculoskeletal disorders (WMSDs) of the main affected body sites among manufacturing workers. Musculoskeletal disorders questionnaire was adopted to investigate the prevalence of WMSDs and the influencing factors among workers from four manufacturing factories in China. The case of WMSDs was defined as the one who had symptoms such as pain, numbness, discomfort, or limitation of activities in one or more of the nine body sites, including neck, shoulder, elbow, wrist/hand, upper back, lower back, hip/thigh, knee and ankle/foot during the last year, which lasted for more than 24 hours and did not completely relieve after rest. Besides, trauma, disability, other acute injuries or sequelae were excluded. The correlation of WMSDs between different body sites was estimated by the prevalence ratio (PR) calculated by log-binominal model. The influencing factors of multi-site WMSDs of the main affected body sites were analyzed by multinomial logistic regression model. The overall prevalence rate of WMSDs was 79.7% among the manufacturing workers. The main affected body sites were lower back, neck, shoulder and upper back, of which the prevalence rates were 62.3%, 55.7%, 45.6%, and 38.7%, respectively. The PR values of WMSDs among these sites were relatively high. The prevalence of multi-site WMSDs involving these four sites at the same time was 25.2%, and that of three to four sites was 41.4%. Multinomial Logistic regression analysis suggested that influencing factors of multi-site WMSDs in 3-4 sites of neck, shoulder, upper back and lower back involved several aspects. Among these factors, females (OR=2.86, 95%CI 2.38-3.33) and individuals with job tenure of 15-19 years (OR=1.87, 95%CI 1.49-2.34) might have higher risk of disease. Biomechanical factors, such as often bending neck forward or holding neck in a forward position for long periods (OR=2.15, 95%CI 1.86-2.48), often twisting neck or holding neck in a twisted position for long periods (OR=1.64, 95%CI 1.40-1.92) and often twisting trunk heavily (OR=1.40, 95%CI 1.20-1.64) might be risk factors. In the aspect of work organization, doing the same work every day (OR=1.73, 95%CI 1.44-2.08), shortage of workers (OR=1.50, 95%CI 1.31-1.71) and often working overtime (OR=1.38, 95%CI 1.20-1.60) might increase the risk of disease. Factors, such as often standing for long periods at work (OR=0.77, 95%CI 0.65-0.91) and feeling breaks sufficient (OR=0.51, 95%CI 0.44-0.59) were suggested to be protective factors with OR<1. The pre-valence rates of WMSDs in neck, shoulder, upper back, and lower back were high among manufacturing workers in this study. The correlation of WMSDs of these four sites was close in this study, and the comorbidity rate of 3-4 sites of these sites was relatively high, suggesting that there might be a multi-site occurrence pattern of WMSDs in "neck-shoulder-upper back-lower back" among manufacturing workers. The main influencing factors of this pattern included individual factors, biomechanical factors and work organization factors.
