Background: Schizophrenia is a complex psychiatric disorder that requires both pharmacological and behavioral treatment and is often accompanied by multimorbidity. Physical activity supports overall health and plays an important role in preventing and managing both somatic and mental disorders. This study aimed to evaluate the impact of an Adapted Physical Activity program using Nordic Walking (AAF-NW) on the quality of life of patients with schizophrenia, depending on the number of steps taken during an eight-week intervention, and to assess its influence on body composition and posture. Methods: A prospective, single-center pilot study was conducted using a pre–post experimental design and direct participatory observation. Eighteen patients from a psychiatric hospital (16 men, 2 women; mean age 43.9 years) completed the intervention. Quality of life (WHOQOL-BREF), musculoskeletal pain (Nordic Musculoskeletal Questionnaire), and subjective exercise intensity (Borg scale, 6–20) were assessed. Measurements were taken before and after the program. All continuous variables (step counts, anthropometric measures, and WHOQOL scores) were tested for normality using the Shapiro–Wilk test and visual inspection of histograms and Q–Q plots. Depending on distribution, parametric or non-parametric tests were applied, with results quantified using appropriate test statistics, effect sizes, and p-values to ensure methodological rigor and transparency. Results: No systematic increase in the number of steps was observed during the training period. A non-significant improvement in quality of life was noted, along with significant reductions in body weight and waist circumference. Conclusions: Regular, structured AAF-NW group activities may potentially support the rehabilitation and treatment process in psychiatric hospitals when implemented on a continuous basis. Although improvements were observed, the findings are exploratory and should be interpreted with caution. Further studies on larger, more homogeneous samples are needed to confirm these preliminary results. Full article

Background: Musculoskeletal disorders (MSDs) are a prevalent health concern among athletes, particularly female university students, who may face sport-specific, physiological, and biomechanical risk factors. In Saudi Arabia, the increasing participation of women in organized sports underscores the need to examine the burden of MSDs in this under-researched population. Objectives: This study aimed to (1) determine the prevalence of MSDs among female university student athletes, (2) identify the most commonly affected body regions, and (3) investigate associations between MSD occurrence and risk factors including sport type, warm-up practices, weekly training frequency, and history of previous injuries. Methods: A cross-sectional study was conducted among 407 physically active female university students aged 16–25 years from multiple Saudi universities. Data were collected using the validated Arabic version of the Nordic Musculoskeletal Questionnaire (NMQ) and a structured risk factor survey. Descriptive statistics, chi-square tests, and logistic regression analyses were used to examine prevalence and associated factors. Results: Among 407 participants, 65.8% reported at least one MSD in the past 12 months. The most commonly affected regions were the shoulders (43.2%), neck (41.8%), and lower back (32.2%). However, multivariate logistic regression revealed that previous injury history (OR = 2.44, 95% CI: 1.47–4.06, p = 0.001) and higher weekly training frequency (OR = 1.23, 95% CI: 1.02–1.49, p = 0.034) were significant independent predictors of MSD occurrence, while participation in team sports showed a borderline association (OR = 1.59, 95% CI: 0.95–2.67, p = 0.079). Conclusions: MSDs are highly prevalent among female university student athletes in Saudi Arabia, particularly affecting the shoulders, neck, and lower back. A history of previous injury and higher weekly training frequency are identified as significant independent predictors of MSD occurrence, while team sport participation showed a borderline association that warrants further exploration. These findings highlight the need for targeted prevention strategies that emphasize rehabilitation continuity—particularly for athletes with prior injuries—and training load management for those with higher weekly training frequency to reduce the risk of MSDs and promote long-term musculoskeletal health.

Background: Musculoskeletal disorders (MSDs) are a significant health problem associated with performing professional activities. The occurrence of pain often determines the type of work undertaken. Healthcare workers and public administration employees are occupational groups at risk of developing musculoskeletal disorders. The aim of this study was to compare the incidence and location of MSDs between two professional groups—healthcare and administrative workers—and to assess their impact on professional functioning. Methods: The study included 339 employees, comprising 188 healthcare workers and 151 administrative workers. An extended version of the Nordic Musculoskeletal Questionnaire (NMQ-E) was used. Results: Healthcare workers experienced MSDs significantly more often than administrative workers, both in the past and in the last 12 months. MSDs in healthcare workers more often led to absenteeism, changes in duties, use of healthcare services, and medication use. The observed differences were statistically significant, particularly in the upper and lower limbs. Conclusions: Musculoskeletal disorders (MSDs) are a significant health problem among healthcare and administrative workers, but they affect healthcare staff much more frequently, especially in the upper and lower limbs. This results in higher sick leave rates, the need to modify duties, and more frequent use of treatment and painkillers. These differences may result from varying working conditions, age, and education, highlighting the need to implement preventive measures tailored to the specific characteristics of each professional group.

The iron and steel industries globally have a high prevalence of occupational injuries, which need to be reduced. Obtaining safety climate information from workers assists in understanding the safety status at the workplace. This study aimed to assess the safety climate in the iron and steel industries and its association with occupational injuries. A cross-sectional study was conducted in four iron and steel industrial sites in Tanzania. Three hundred and twenty-one workers from the production lines and 50 managers/supervisors participated. The data were collected by interviews using the Kiswahili version of the Nordic Safety Climate Questionnaire (NOSACQ-50) and the modified International Labor Organization (ILO) manual on methods for occupational injuries. The managers/supervisors scored higher than the workers in five of the NOSACQ-50 dimensions. Most workers with low scores on safety climate had experienced occupational injuries. Analyses of the workers who had been injured at work showed that the dimensions ‘management safety priority and ability’, and ‘management safety justice’ were significant predictors of occupational injuries in the iron and steel industries, when adjusting for working years and working hours per day. This indicates that safety climate is a predictor of occupational injuries, and it is important to improve the safety priorities and commitments among the employees. Full article

Background: Several studies have examined the prevalence of musculoskeletal pain (MSP) among university students internationally. We aimed to assess the prevalence, pattern, and potential risk factors for MSP among Majmaah University students in Saudi Arabia. Methods: A cross-sectional questionnaire was administered to students from different faculties at Majmaah University. We collected data via the validated Arabic versions of the Standardized Nordic Musculoskeletal Questionnaire, the International Physical Activity Questionnaire, and the Perceived Stress Scale. Bivariate and multivariate logistic regression analyses were performed to explore associations between MSP and demographic, ergonomic, lifestyle, and psychosocial variables. Results: A total of 257 students (n = 195, 75.9% female; n = 62, 24.1% male) were included in this study. The 12-month prevalence of MSP was 225 (87.5%), with the lower back (n = 119, 46.3%) and neck (n = 113, 44.0%) regions being the most affected. Compared with male students, female students reported a higher MSP prevalence (90.3% vs. 79.0%, p = 0.035). The multivariable model was significant (likelihood-ratio χ² = 26.042, df = 7, p < 0.001), accounted for Nagelkerke R² = 0.182 of variance, and showed good calibration (Hosmer–Lemeshow χ² = 8.505, df = 8, p = 0.386). Perceived stress was the only independent predictor of 12-month MSP (β = 0.084, adjusted OR = 1.087, 95% CI 1.034–1.143, Wald χ² = 10.732, p = 0.001), while sex, smoking, academic workload, and sleep duration were non-significant (all p > 0.127). Conclusions: MSP appears to be prevalent among Majmaah University students, with psychological stress emerging as a key independent risk factor. Preventive strategies should include stress management prioritization and ergonomic and physical activity education to support university student well-being. Full article

Background: Orofacial dysfunctions are a source of discontent and impair daily living activities. Patients with hearing impairments exhibit an elevated risk of stomatognathic system changes. Hence, this pilot study aims to evaluate changes in stomatognathic system functions in patients with hearing impairments and cochlear implants. Methods: During the examination, the Nordic Orofacial Test-Screening was used to assess orofacial functions. The range of motion within the temporomandibular joints was measured using a vernier caliper. A socio-medical study was conducted to collect data regarding the patients, the cochlear implant sides, and the methods of communication. Results: The statistical analysis showed a significant difference in the total NOT-S scores (p < 0.001) and examination scores (p < 0.001) between patients with hearing impairments and the control group. These significant differences of the total NOT-S score and examination score have large effect sizes (r > 0.5). In particular, significant differences were observed in the results of maximum mouth opening (p = 0.006) and right laterotrusion (p = 0.020). Differences were also observed in the answers regarding the method of communication and the examination score of the NOT-S questionnaire (p = 0.040). The 6A of the NOT-S significantly affected the examination score (p = 0.015) and the total NOT-S score (p = 0.037), while the result of section 6B only significantly affected the NOT-S examination score (p = 0.032). Conclusions: Patients with hearing impairments presented orofacial dysfunctions significantly more often than the control group. The side of cochlear implant implantation is important for stomatognathic system changes. Full article

Background: Dietary advice for Paralympic athletes (PAs) with a spinal cord injury (PAs-SCI) requires particular attention and has been widely studied. However, currently, no particular attention has been addressed to nutritional guidelines for athletes with an amputation (PAs-AMP). This study aimed at filling up this gap, at least partially, and compared veteran PAs-SCI with PAs-AMP. Methods: A sample of 25 male PAs (12 with SCI and 13 with AMP), recruited during two training camps, was submitted to the following questionnaires: allergy questionnaire for athletes (AQUA), Nordic Musculoskeletal Questionnaire (NMQ), Starvation Symptom Inventory (SSI), neurogenic bowel dysfunction (NBD), orthorexia (ORTO-15/ORTO-7), alcohol use disorders identification test (AUDIT), and Mediterranean diet adherence (MDS). The PAs were also submitted to the following measurements: dietary Oxygen Radical Absorbance Capacity (ORAC) and intakes, body composition, handgrip strength (HGS), basal energy expenditure (BEE), peak oxygen uptake (VO_2peak), peak power, peak heart rate (HR), post-exercise ketosis, and antioxidant response after a cardiopulmonary exercise test (CPET) to voluntary fatigue. Results: Compared to PAs-AMP, PAs-SCI had higher NBD and lower VO_2peak (p < 0.05), peak power, peak HR, peak lactate, phase angle (PhA) of the dominant leg (p < 0.05), and ORTO15 (p < 0.05). The latter was related to NBD (r = −0.453), MDS (r = −0.638), and ORAC (r = −0.529), whereas ORTO7 correlated with PhA of the dominant leg (r = 0.485). Significant differences between PAs-AMP and PAs-SCI were not found in the antioxidant response, glucose, and ketone levels after CPET, nor in dietary intake, AUDIT, AQUA, NMQ, SSI, BEE, HGS, and FM%. Conclusions: The present study showed that PAs-SCI and PAs-AMP display similar characteristics in relation to lifestyle, energy intake, basal energy expenditure, and metabolic response to CPET. Based on both the similarities with PAs-SCI and the consequences of the limb deficiency impairment, PAs-AMP and PAs-SCI require personalized nutritional advice. Full article

Background/Objectives: The Nordic Orofacial Test-Screening (NOT-S) is a versatile tool used for the assessment of orofacial function. The aim of this study was to introduce the Polish version of the NOT-S along with the results of its cultural adaptation. Methods: The original NOT-S was validated into the Polish language in accordance with the current questionnaire translation standards, including the cultural adaptation, which consisted of an examination of Polish society. The pilot study, as a cultural adaptation, was carried out among fifty people between the ages of 3 and 34 (Mean—15.8, SD—8.9). Results: During the translation, three word discrepancies were noted, and also many linguistic equivalences, such as semantic, empirical, conceptual, and other differences, were reported. The average total NOT-S score during cultural adaptation was 1.62 (SD 1.16; Range 0–5). Abnormalities in section III, i.e., habits (78%), were found most frequently in the subjects. A thorough data analysis showed statistically significant results in section IV of the interview, i.e., chewing and swallowing (p = 0.00073), and also significant results in section 3 of the examination, i.e., facial expression (p = 0.00006). Conclusions: The Polish version of the NOT-S is linguistically comprehensible and culturally equivalent, and can be used for the examination of children, adolescents, and adults. The findings of this study indicate that orofacial function screening is advisable in the healthy population. Full article

(1) Background: Work-related musculoskeletal disorders (WMSDs) are a major occupational health concern in the construction industry owing to the physically demanding tasks and poor ergonomic conditions present. Limited data exist on the prevalence of WMSDs and their ergonomic determinants among construction workers in India. This study investigated the prevalence of work-related musculoskeletal disorders (WMSDs) and the associated ergonomic risk factors among construction workers in India. (2) Methods: This cross-sectional study was conducted among 250 construction workers in India. Data on musculoskeletal disorders were collected using the Nordic Musculoskeletal Questionnaire (NMQ), and ergonomic risk was assessed using the Rapid Entire Body Assessment (REBA) tool. Logistic regression was used to identify factors associated with WMSDs, and Spearman’s correlation was used to assess the relationship between the REBA scores and the number of affected body regions. (3) Results: The prevalence of WMSDs was 60.4%. The most affected regions were the lower back (48%), knees (45%), shoulders (40%), and the neck (30%). The REBA scores indicated that 60% of the workers were at high or very high ergonomic risk and 30% at medium risk. Workers in the high/very high-risk category had significantly higher odds of developing WMSDs (OR = 4.5, 95% CI: 1.8–11.2, p = 0.001). Age above 40 years was also significantly associated with WMSDs (OR = 3.5, 95% CI: 1.2–10.2, p = 0.02). (4) Conclusions: This study demonstrated a high prevalence of WMSDs among Indian construction workers and established a clear association with poor ergonomic conditions. Targeted ergonomic interventions, including posture improvement, tool redesign, and safety training, are essential for reducing the risk of WMSDs in this population. Full article

Introduction: Musculoskeletal disorders (MSDs) are a significant occupational health concern worldwide, particularly among healthcare professionals such as laboratory technicians. MSDs lead to chronic pain, decreased productivity, and reduced quality of life. This study aimed to investigate the prevalence of MSDs and associated ergonomics risk factors among Saudi clinical laboratory technicians. Methodology: This cross-sectional study was conducted on 167 clinical laboratory technicians in Taif city, Saudi Arabia. Data were collected through an online self-administered questionnaire, distributed via Google Forms. The questionnaire collected demographics information, assessed the prevalence of musculoskeletal pain using the Nordic Musculoskeletal Questionnaire (NMQ), and evaluated ergonomics risk factors using the Dutch Musculoskeletal Questionnaire (DMQ). Results: In total, 77.3% of the sample exhibited musculoskeletal issues in the last 12 months, with lower back (52.1%), neck (48.5%), and shoulders (40.7%) being the most frequent muscular complaints among laboratory technicians. Experience and nationality showed significant associations with MSDs (p ≤ 0.05). Lower back and neck complaints were commonly recorded with multiple laboratory tasks, including sustained sitting and standing and repetitive movement, whereas lower back and shoulder pain were notably prevalent with pipetting work. Conclusions: Work-related musculoskeletal disorders were highly apparent in laboratory practice. Periodic ergonomic training is mandated among laboratory personnel to limit occupational disability.

The aim of the study was to verify the relationship between musculoskeletal pain of elite Polish goalball players and selected physique and posture characteristics. We examined 12 players. The mean age was 21.8 ± 6.0 years, and a mean training experience of 6.3 ± 3.4 years. Physique (body mass, body height, waist circumference, fat tissue, fat-free soft tissue) and posture (thoracic kyphosis and lumbar lordosis) and range of motion (in the thoracic and lumbar regions) were assessed. The incidences and locations of musculoskeletal pain were identified using the Nordic Musculoskeletal Questionnaire, covering the period from the last seven days (NMQ-7) and six months (NMQ-6). Due to the small group size, non-parametric tests (Spearman’s rank correlation) were used. The significance level was set at p < 0.05. Players were more likely to report musculoskeletal pain in the last six months than in the previous week. Pain reported in both NMQ6 and NMQ7 was most common in the wrists/hands and lower back, and, in NMQ6, also in the shoulders and ankles/feet. There were significant negative correlations of total NMQ7 with lumbar lordosis angle in the habitual standing position (R = −0.6; p = 0.04), trunk flexion (R = −0.8, p = 0.002), and trunk extension (R = −0.6; p = 0.03), and a positive correlation with thoracic kyphosis angle in trunk flexion (R = 0.8, p = 0.005). There was a statistically significant, inversely proportional relationship of thoracic kyphosis angle values in the habitual position (R = −0.58; p = 0.049) and thoracic kyphosis angle THA in trunk flexion (R = −0.6; p = 0.038) with time of disability. Relationships between some body posture parameters and musculoskeletal pain in the studied athletes were also noted. Full article

Background: Low back pain (LBP) and musculoskeletal disorders are highly prevalent among agricultural workers. However, there is limited epidemiological evidence from rural regions of Ecuador, where working and living conditions may differ substantially from those in other settings. This study aimed to identify predictors of LBP among farmers in rural Ecuador to inform locally relevant prevention strategies. Methods: Participants aged 30 to 60 years (n = 103) were recruited through a traveling health clinic. Participants were assessed with behavioral and sociodemographic self-report questionnaires and anthropometric measurements. Low back pain (LBP) was assessed using the Standardized Nordic Musculoskeletal Questionnaire, which asked about symptoms experienced in the past 12 months. Bivariate (Chi-square and Fisher exact tests) and multivariate (binary logistic regression) analyses were conducted to explore associations between risk factors and LBP in individuals aged 30 to 60 years. Results: LBP was highly prevalent, affecting 78.6% of participants. Behavioral patterns were mixed, with low rates of smoking and moderate alcohol and coffee consumption associated with LBP. A normal body mass index (BMI) was observed in 66% of the sample, and over half reported stable mood and good self-perceived health. In the binary logistic regression analysis, only education level significantly predicted LBP, with secondary education acting as a protective factor. Conclusions: While lower back pain was widespread in the population studied, most risk factors that were analyzed were not significantly associated with its presence. Full article

Objectives: A dentist may assume incorrect working positions throughout their professional career, which can lead to musculoskeletal disorders (MSDs). This study aimed to quantify the prevalence of self-reported MSDs in dentists and the body region most affected, as well as to evaluate the most frequent working position, the area of work and the age group most frequently associated with MSDs. Methods: This is a cross-sectional observational study adhering to the STROBE and CHERRIES guidelines, approved by the local Ethics Committee. An online questionnaire (including the Nordic Musculoskeletal Symptoms Questionnaire) was applied to a convenience sample of Portuguese and Italian dentists. Data analysis was conducted with non-parametric comparisons (IBM© SPSS^® Statistics vs. 28.0, p < 0.05). Results: A total of 341 dentists (170 Portuguese, 171 Italian) aged 18–75 years participated. The prevalence of self-reported MSDs in Portugal and Italy was 78.8% and 81.9%, respectively. The most affected self-reported MSD body regions were the neck (65.3% Portuguese and 61.4% Italian dentists), shoulder (49.4% Portuguese and 39.2% Italian) and lumbar region (52.4% and 39.2%, respectively). The neck region was the one reported to cause the highest work absenteeism. The higher age group (41–50 years and higher) has a higher risk for self-reported MSD. Multivariate analysis highlighted increased practice time as a significant risk factor for MSDs in the previous year in both countries. Age group, practice duration and work position relative to the patient were significantly linked to MSD occurrence and work avoidance. Conclusions: Dentists showed a high prevalence of self-reported MSD despite performing clinical activity mostly seated. It was concluded that dentists older than 40 years and those who have been working for more than 20 years have a higher risk of MSD, and that endodontics is the area where they report feeling more discomfort. Dentists should be encouraged to take more breaks between appointments and regular exercise to prevent the development/progression of MSDs. Full article

This study examines safety climate perceptions in construction using two models: the Safety Climate Model (SCM) and the Nordic Safety Climate Questionnaire (NOSACQ-50). Data from 20 projects of various sizes (ranging from 11 to 50 floors) and company years of experience (1-25+) were analyzed using the 5-point Likert scale and ANOVA tests. SCM and NOSACQ-50 contained 10 and 7 questions, respectively. Responses were gathered from safety officers and supervisors. Results revealed insights into safety culture and the impact of management practices on safety perceptions in high-rise construction. The study found that safety climate perceptions were relatively poor, with a score of 3.865 for the SCM and 3.600 for NOSACQ-50. The findings emphasize the need for stronger safety practices at higher organizational levels, particularly in management, expressed by the findings of 3.3 and 3.5 in means of management commitment and safety climate fostering in NOSACQ-50 and the relatively large variance in the NOSACQ-50 model (0.23), control, and leadership. Cronbach’s alpha values were 0.935 and 0.943 for SCM and NOSACQ-50, respectively, indicating internal adherence of the models to safety practices. A moderate positive correlation of 0.470 between the two models suggests that both measures overlap but there exist distinct aspects of safety perceptions. In SCM, the highest-rated factors were safety equipment availability and employee participation in safety training, and employees feel the company prioritizes their well-being, highlighting the importance of resources and engagement. Current work pace does not compromise safety measures and protocols received the lowest score. In NOSACQ-50, the highest scores were for management’s commitment to safety and safety communication, while the lowest scores were found for management actions, reflecting their commitment to worker safety management and employees’ shared responsibility, suggesting areas for future improvement. The study underscores that project size and company years of experience do not significantly affect safety perceptions, but effective safety communication, management commitment, and employee engagement are crucial. The findings indicate that the NOSACQ-50 better elucidates safety climate core performance as depicted by the larger coefficient of variance (0.23 compared to 0.16). Full article

Introduction: In 2021, 10.5% of people aged 20–79 had diabetes, projected to rise to 12.2% by 2045, causing early deaths and straining healthcare systems. Musculoskeletal (MS) pain is common, affecting many workers and the general population. Prediabetes, notably impaired fasting glucose (IFG), is linked to increased MS pain risk. Objective: This study aims to assess IFG’s impact on MS pain and specific pain sites to aid prevention strategies. Methods: This cross-sectional study used the ‘2023 Employee Occupational Safety and Health Management Database’ from a Taichung hospital. It included health checks, demographics, living and work data, and MS pain surveys. Out of 2369 staff members contacted, 1039 valid responses were analyzed, excluding incomplete data, diabetes history, or fasting blood glucose levels above 125 mg/dL. Data on sex, age, marital status, coffee and alcohol consumption, sleep duration, exercise habits, height, weight, chronic diseases, profession, work hours, shift work, and education level were collected. Fasting blood glucose was verified using American Diabetes Association criteria (100–125 mg/dL). The Nordic Musculoskeletal Questionnaire (NMQ) measured MS pain frequency and severity, creating a pain degree index. Results: Overall, 21.17% had IFG. Participants were mostly female (85.18%), averaging 37.50 years. Neck and shoulder pain risk was linked to sex, coffee and alcohol consumption, sleep, exercise, chronic diseases, work hours, and IFG. Ankle pain risk was linked to coffee and alcohol consumption. IFG, coffee, alcohol, sleep under 6 h, chronic diseases, and work hours were independent risk factors for neck and shoulder pain. IFG was a risk factor for those without overweight or obesity. A mediation model tested IFG’s indirect effect on neck and shoulder pain among overweight or obese individuals, showing that IFG mediates the relationship between being overweight or obese and increased neck and shoulder pain risk. Conclusions: Among female-dominated healthcare workers, IFG, daily coffee, recent alcohol consumption, less than 6 h of sleep, chronic diseases (excluding diabetes), and longer work hours are independent risk factors for neck and shoulder pain. IFG mainly affects these areas, increasing pain risk regardless of body weight. Healthy blood glucose levels are associated with a lack of musculoskeletal pain, suggesting a novel prevention approach needing further study. Full article
