Work ability and productivity among dentists: associations with musculoskeletal pain, stress, and sleep

Work-related musculoskeletal pain Among Jordanian dentists: Prevalence and associated demographic, physical, and psychosocial factors

ObjectivesMusculoskeletal pain is recognized as a major occupational health hazard among dentists worldwide. Physical exertion at work plays a major role in the development of musculoskeletal problems. There is growing evidence that work-related psychosocial factors may also contribute to musculoskeletal pain. Therefore, the aim of this study was to investigate the prevalence of work-related musculoskeletal pain and its demographic, physical, and psychosocial risk factors among dentists in Jordan.MethodsThis cross-sectional study utilized a validated self-administered questionnaire distributed to 272 currently working Jordanian dentists. The questionnaire consisted of four sections: sociodemographic information, work physical characteristics, work-related psychosocial factors, and musculoskeletal pain assessment.ResultsFifty-one percent (51%) of Jordanian dentists reported experiencing musculoskeletal pain in the last 12 months. Neck pain (42%), followed by shoulder pain (40%), and lower back pain (40%), were the most common among dentists in Jordan. Increasing age, being a female, and obesity were significantly associated with musculoskeletal pain while smoking, exercise, and specialty level did not. A positive correlation between musculoskeletal pain and unfavorable physical characteristics at work was identified. In addition, increased work stress was positively correlated with musculoskeletal pain.ConclusionThis study showed a high prevalence of musculoskeletal pain among Jordanian dentists. Increasing dentists' and healthcare authorities' awareness about factors associated with work-related musculoskeletal pain is needed. Educational programs targeting dentists at risk of developing musculoskeletal pain might be of potential preventive value.

Mediating effect of occupational stress between skeletal muscle disorders and depressive symptoms in firefighters: a Structural Equation Modeling approach

OBJECTIVES

The purpose of this study was to explore the relationship between skeletal muscle disorders (SMD), occupational stress (OS) and depressive symptoms (DS) among firefighters.

MATERIAL AND METHODS

A cross-sectional survey was conducted among firefighters in Chongqing, China. Descriptive statistic and correlation analyses were performed by using SPSS 26.0. AMOS 24.0 was used to construct the structural equation modeling between SMD and DS. The mediating effect of OS was also evaluated.

RESULTS

The results demonstrate that SMD can predict DS (β = 0.25, p < 0.001) and OS (β = 0.39, p < 0.001) positively, OS positively predicted DS (β = 0.39, p < 0.001) after controlling for SMD. Additionally, OS has a partial indirect effect between DS and SMD (indirect effects = 0.209, 95% CI: 0.093-0.372, p < 0.001).

CONCLUSIONS

Occupational stress has a partial indirect effect between SMD and DS among firefighters. Skeletal muscle disorders could affect DS not only directly, but also indirectly, by affecting OS. These findings may be of great significance and contribution to the future research of firefighters' occupational health. Int J Occup Med Environ Health. 2025;38(1):18-29.

Lifestyle, Working Conditions, and Quality of Life Among Dentists in Kazakhstan

Background: The study of working conditions and the quality of life (QoL) of medical workers has not lost its relevance worldwide. This highlights the need to understand the many aspects of life that may characterize physician performance and satisfaction with working conditions. This is extremely important for providing quality and safe medical care. This research aims to study dentists' lifestyles and working conditions in the Republic of Kazakhstan and the impact of these indicators on their QoL. Methods: This article presents the results of a cross-sectional survey of a sociological questionnaire conducted with the participation of 254 dentists in Kazakhstan. Results: Only a third of dentists follow a healthy lifestyle. In total, 39% of dentists currently smoke, and 24% drink alcohol. Dentists with more than 20 years of experience have a worse QoL and have the lowest scores in all domains compared to dentists with less experience. The lowest score was scored for mental health (mean = 51.81). On all scales, dentists who worked more than 40 h a week reported decreased QoL; the lowest score was in the "mental health" domain (mean = 52.80). Conclusion: The QoL of dentists in Kazakhstan is negatively affected by their working hours and long working experience. Measures are necessary to improve their working conditions, work schedule planning, and mental health.

Effect of a Novel Ergonomic Sheath on Dental Device-Related Muscle Work, Fatigue and Comfort-A Pilot Clinical Study

Background: Dental instrumentation with hand-held devices is associated with discomfort, fatigue and musculoskeletal diseases or repetitive stress injuries. The goal of this in vivo study was to determine the effect of an ergonomic handle sheath on muscle work, comfort and fatigue associated with (a) piezoelectric scaling by hygienists with and without musculoskeletal disorders (MSDs), and (b) dental cavity preparation by healthy dentists using a dental micromotor. Materials and Methods: Two groups of ten hygienists each tested the piezoelectric scaler. Hygienists in Group 1 had no MSDs, while those in Group 2 had been diagnosed with MSDs. Additionally, ten dentists with no MSDs used a dental micromotor to prepare four standardized cavities. Time-based work in four muscles, comfort and fatigue were recorded in the presence and absence of an add-on soft, insulating handle sheath. Data were analyzed using a repeated measures analysis of variance model with Tukey's post-hoc test. Results: Comfort, fatigue and muscle work were significantly better for both devices when the sheath was used. While hygienists with MSDs used more muscle work to complete the set scaling task, and the sheath-related reduction in work was somewhat greater, these MSD-related differences did not quite reach significance. Conclusions: The results of this pilot study show that the ergonomic performance of an ultrasonic scaler and a dental micromotor may be improved by the use of an ergonomic handle sheath.

High Prevalence of Work-Related Musculoskeletal Disorders Among Dentists: A Cross-Sectional Study From Kerala, India

BACKGROUND

 Literature on the prevalence of musculoskeletal disorders (MSD), work ability, and associated factors among dentists is limited. Therefore, this study aimed to determine the prevalence of MSD, work ability, and associated factors among dentists in Kerala, India.

METHODS

 This cross-sectional study was conducted among 290 dentists (median age: 34 years, 47% male), selected from a list of dentists in a district of Kerala. Information on MSD and work ability were collected using a structured, pre-tested questionnaire administered both online and through direct interviews. Factors associated with MSD were analyzed using multivariable regression analysis.

RESULTS

 The prevalence of MSD in the past 12 months was 86.9% (95% CI: 83.1 - 90.9), and in the past seven days was 42.4% (95% CI: 36.7 - 48.08). Among those reporting MSD in the last 12 months, 21.4% experienced it in two sites. Of the nine regions assessed, the neck was the most affected over the past 12 months, with 57.6% reporting discomfort, while the lower back was the most affected in the last seven days (21.4%). Work ability was rated as excellent by 24.5% of participants and good by 51.7%. In the regression analysis, no significant association was found between socioeconomic factors and MSD during either time period. However, bivariate analysis showed that dentists who were overweight and those aged 34 years or older reported significantly more knee-related MSD in the past seven days (p=0.033 and p=0.037, respectively).

CONCLUSION

 Despite the high prevalence of MSD among dentists, more than three-fourths reported good or excellent work ability. Implementing mandatory ergonomic assessments and interventions in dental workplaces may help reduce MSD among dentists.

Emotional and Work-Related Factors in the Self-Assessment of Work Ability among Italian Healthcare Workers

The Work Ability Index (WAI) is the most commonly used tool for evaluating work capacity. Self-assessments made by workers can be influenced by various occupational and emotional factors. We wanted to study the association of work-related factors, such as work annoyance, stress, overcommitment, job satisfaction, social support, and emotional factors, such as anxiety, depression, and happiness, with work ability, in a sample of 490 healthcare workers from an Italian public health company. A principal component analysis indicated the presence of two components of the WAI questionnaire; the first expresses "subjectively estimated work ability" (SEWA), and the second refers to "ill-health-related work ability" (IHRWA). Using stepwise multiple hierarchical linear regression, we identified the factors that best predicted the total score on the WAI and on the two components. The total score was negatively predicted by anxiety, depression, a lack of happiness, low job satisfaction, overcommitment, and work annoyance. Age, being female, anxiety, and occupational stress were associated with a reduction in the IHRWA component score, while overcommitment, work annoyance, a lack of social support, depression, and a lack of happiness were negatively associated with the SEWA component. These results can help interpret those of epidemiological studies and provide guidance on ways to improve work ability.

Effect of a Novel Adaptive Handle Design on the Ergonomic Performance of Periodontal Curettes in Dental Hygienists with and without Musculoskeletal Disorders: A Pilot Clinical Study

(1) Background: Musculoskeletal disorders (MSDs), discomfort, fatigue, pain, and other acute and chronic work-related injuries are common among dental clinicians. Hand instruments constitute a primary risk factor for these conditions. The overall goal of this study was to compare in dental hygienists with healthy hands, and in those with MSDs, the effect of three different handle designs on instrumentation-related muscle work, comfort, fatigue, and quality of tactile feedback. (2) Methods: Clinicians tested three periodontal curettes: one with a novel adaptive silicone handle, another with a rigid resin handle, and the third with a rigid silicone handle. Ten hygienists-five with MSDs and five without-each scaled three typodonts using the three different curettes. Statistical analysis was performed using a General Linear Model (GLIM) and Tukey's post hoc test, and a significance level of p < 0.05 was implemented. (3) Results: On average, mean comfort and fatigue across all instruments were significantly worse in testers with MSDs, who also expended significantly more work to complete the same task. In all testers, a novel adaptive handle design was associated with significantly reduced total muscle work and post-instrumentation fatigue, as well as better comfort than conventional rigid handle designs. (4) Conclusions: An adaptive curette handle design demonstrated significantly better ergonomic outcomes than conventional rigid curette handle designs. Hygienists with MSDs expend significantly more muscle work during dental instrumentation.

Space-time analysis of work-related musculoskeletal disorders in Brazil: an ecological study

This study aimed to analyze the incidence of work-related musculoskeletal disorders (WMSD) in Brazil from 2007 to 2019, examining the spatial, temporal, and spatiotemporal patterns of their occurrence. An ecological time series study was conducted using spatial analysis techniques. WMSD morbidity data from 2007 to 2019 were collected from the Brazilian Information System for Notificable Diseases of the Brazilian Health Informatics Department. Incidence rates were standardized and smoothed using the local empirical Bayes' theorem. Time trends were analyzed by segmented linear regression. Spatial analysis was performed using Moran's univariate global (I) and local (LISA) indexes. The spatiotemporal scan statistic was used to identify high-risk spatiotemporal clusters for WMSD. A total of 93,387 cases of WMSD were recorded in Brazil. Temporal trends showed an increase in all regions except the Northeast, which remained stable. The incidence of WMSD showed a spatial dependence, with spatial and space-time clusters identified, especially in the Southeast region, overlapping the largest economic-industrial center of the country. The spatiotemporal clustering observed in one region suggests the highest level of industrial and economic development. Our findings highlight the need to implement intersectoral surveillance policies, inspect working conditions, and invest in the prevention and promotion of workers' health.

Musculoskeletal disorders and risk indicators for pain chronification among German dentists: A cross-sectional questionnaire-based study

OBJECTIVES

The aim of this study was to determine the prevalence of musculoskeletal (MS) disorders in practicing German dentists and identify risk factors for pain chronification.

METHODS

This was a cross-sectional, quantitative, questionnaire-based study in which the validated German version of the Örebro Musculoskeletal Pain Questionnaire was sent out to practicing German dentists.

RESULTS

Of the 8,072 questionnaires sent out, 576 dentists responded (60.2% men, 39.8% women; mean [SD] age, 50 [10.1] years; response rate, 7.1%). Overall, 344 dentists had current pain at 719 pain sites (point prevalence, 59.7%). The risk of chronic pain in dentists with current MS pain was high in 28.5% (n = 98), moderate in 30.5% (n = 105), and low in 41% (n = 141). The multivariate logistic regression analysis showed that specialization in restorative dentistry was associated with a significantly higher risk of experiencing pain chronification (odds ratio [OR], 3.94; P = .008), followed by specialization in pediatric dentistry (OR, 0.35; P = .048). A history of current pain, particularly current leg pain, was predictive of higher chronification risk (OR, 22.0; P < .001) and neck pain (OR, 4.51; P = .001).

CONCLUSIONS

Almost two-thirds of practicing German dentists have MS pain, and one-third of these have a moderate through high risk of developing pain chronification. These health problems have an adverse impact on their ability to successfully perform dental services, with the potential for prolonged sick leave, disability, and early retirement. Accordingly, these problems deserve greater attention from the scientific community (identification of risk factors), universities (sensitization and education), and policy makers (development and implementation of appropriate countermeasures for MS disorders in the dental profession).

PRACTICAL IMPLICATIONS

Knowing the risk factors associated with acute and chronic MS pain may help dentists take preventive measures and thereby improve their physical well-being and work-related quality of life.

Analysis of musculoskeletal pains and productivity impacts among hispanic construction workers

This study investigated the top three musculoskeletal pains (MSP) among Hispanic construction workers in Texas and the relationship between sleep hours, age, and MSPs on worker productivity. The study recruited 228 participants from 28 small construction companies and surveyed them on their occupation, age, sleep hours, MSP, and the impact of pain on productivity. The results indicated that Foot pain was the most common among these workers, followed by Back pain and others. Additionally, the study found that the Foot was the most common body part reported with MSP among roofers, drywall installers, laborers, and helpers. The study conducted a three-factor ANOVA test to analyze if there were any significant differences in productivity based on age, number of MSPs, and sleep hours. The study found that MSPs and sleep hours significantly impacted productivity. However, there was no significant effect of age. The results also showed that the number of MSPs significantly impacted productivity, with an increase in MSPs leading to a more severe impact on productivity. Additionally, those who slept less than 6 h per day had a more severe impact on productivity than those who slept more. The study suggests that targeted interventions to improve musculoskeletal health and productivity in this population are needed and highlights the importance of considering Hispanic construction workers' specific needs when implementing safety measures and addressing pain management in the workplace.

Musculoskeletal disorders and work ability among dentists and dental students in Finland

BACKGROUND

Musculoskeletal disorders are leading causes for long sickness absences and early retirement. Dental work is physically strenuous, and many studies have shown a relation between work-related MSDs and dentistry. However, fewer studies have focused on how these conditions affect the work ability of dentists.

OBJECTIVE

This study aimed to reveal the relationship between MSD, work ability and sickness absences in Finnish dentists and dental students.

METHODS

A questionnaire was sent to 1200 dental workers and students. It inquired of age, gender, use of dental loupes, physical exercise, use of health care, and site, length and frequency of musculoskeletal complaints. Work ability was assessed with four parameters: work ability score (WAS), future work ability (FWA), self-estimation of MSD-related work disability, and sickness absence days.

RESULTS

The questionnaire gained 255 responses (response rate 21%). The majority (90%) of the respondents had experienced MSD during the past year but only eleven percent of them had been on sick leave. MSDs correlated significantly with WAS, FWA and MSD-related work disability. Results remained significant even age adjusted. Age was a strong predictor of declined work ability, but gender, physical exercise or dental loupe use did not have a significant impact.

CONCLUSIONS

Despite all the ergonomic advances in modern dentistry, the occurrence of MSD symptoms is still high. MSDs seem to affect dentists' work ability significantly, but amount of sickness absence is relatively low, which may indicate a high level of presenteeism.

The Relationship Between eHealth Literacy and Mental Health of Adult Workers: A Cross-Sectional Study

The current cross-sectional study aimed to investigate eHealth literacy among adult workers in China and explore the relationship between eHealth literacy and mental health in this population. Convenience sampling was used to conduct a survey among adult workers aged 18 to 60 years. Potential participants were chosen from those who completed physical examinations at the Health Management Center of one hospital in China. Participants' eHealth literacy and mental health were assessed using the eHealth Literacy Scale, Patient Health Questionnaire, Generalized Anxiety Disorder Scale, and Perceived Stress Scale. Mean scores for eHealth literacy and perceived stress were 28.39 (SD = 5.78) and 5.49 (SD = 2.61), respectively. Depression and anxiety were found in 8.2% and 10.1% of participants, respectively. Multivariate logistic regression analysis showed that a 1-point increase in eHealth literacy score was associated with a 7% decrease in depressive symptoms (odds ratio [OR] = 0.93, 95% confidence interval [CI] [0.88, 0.99]) and a 6% decrease in anxiety symptoms (OR = 0.94, 95% CI [0.89, 0.99]). Furthermore, multiple linear regression analysis showed that perceived stress decreased 0.08 points (B = -0.08, 95% CI [-0.13, -0.04]) with every 1-point increase in eHealth literacy score. Thus, eHealth literacy has the potential to reduce risk of depression, anxiety, and perceived stress, and to promote the mental health of adult workers.

Musculoskeletal disorders among doctors and nursing officers : an occupational hazard of overstrained healthcare delivery system in western Rajasthan, India

BACKGROUND

The present study was conducted to estimate the prevalence and distribution of MSDs in different anatomical regions among Doctors and NO and to determine their ergonomic risk factors and predictors.

METHODS

This cross-sectional study was conducted in an apex institution in Western India. The socio-demographic information, medical and occupational history, and other personal and work-related attributes were captured using a semi-structured questionnaire, which was developed and finalized by piloting on 32 participants (who were not part of the study). Nordic Musculoskeletal and International Physical Activity Questionnaires were used to assess MSDs and Physical activity. Data were analyzed using SPSS v.23. Prevalence of Musculoskeletal Symptoms (M.S.), Multisite Musculoskeletal Symptoms (MMS), and Widespread Musculoskeletal Symptoms (WMS) were calculated. A comparison was made to estimate the burden and distribution of MSD among Doctors and Nursing officers. Logistic regression was applied to identify the predictors of MSDs and pinpoint the risk factors associated with MSDs.

RESULTS

A total of 310 participants, of which 38.7% were doctors, and 61.3% were Nursing Officers (NOs) were included in the study. The mean age of the respondents was 31.63 ± 4.9 years. Almost 73% (95%CI: 67.9-78.1) of participants had MSD in the last 12 months, with approximately 41.6% (95%CI: 36.1-47.3) suffering from MSDs in the previous seven days of the survey. The lower back (49.7%) and the neck (36.5%) were the most affected sites. Working in the same position for a long time (43.5%) and not taking adequate breaks (31.3%) were the highest self-reported risk factors. Females had significantly higher odds of having pain in the upper back [aOR:2.49(1.27-4.85)], neck [aOR:2.15(1.22-3.77)], shoulder [aOR:2.8 (1.54-5.11)], hips [aOR:9.46 (3.95-22.68)] and knee [aOR:3.8(1.99-7.26)].

CONCLUSIONS

Females, who are NOs, work for > 48 h per week, and fall in the obese category were significantly at more risk of developing MSDs. Working in an awkward position, treating an excessive number of patients in a day, working in the same position for a long period, performing repeated tasks, and not having enough rest breaks were significant risk factors for MSDs.

The Effect of Stress of COVID-19 on Chinese Adults' Work-Family Conflict: Testing a Moderated Mediation Model

Purpose

The current study examined the effect of stress of COVID-19 on work-family conflict, how perceived work ability may mediate this effect, and lastly how perceived social support may moderate the various indirect pathway during COVID-19 pandemic.

Methods

A total of 2558 Chinese adults were recruited from the first author's university completed the questionnaire including stress of COVID-19 scale, work-family conflict, perceived social support and perceived work ability scale.

Results

The present study showed that stress of COVID-19 was positively associated with work-family conflict while negatively associated with perceived work ability, which in turn, was negatively associated with work-family conflict. Perceived social support magnified the effects of perceived work ability on work-family conflict.

Conclusion

Findings of this study shed light on a correlation between stress of COVID-19 and work-family conflict. Moreover, this study emphasizes the value of intervening individuals' perceived work ability and increasing the ability of perceived social support in the context of COVID-19.

Assessing the impact of job demands and hazardous workload activities on musculoskeletal symptoms in stone, sand, and gravel mining operations

BACKGROUND

Musculoskeletal disorders (MSDs) and associated musculoskeletal symptoms (MSS) are problematic in stone, sand, and gravel mining. Research is needed to explore relationships between job demands, work-related hazards and MSS.

OBJECTIVE

An exploratory study was conducted in Indiana during 2019-2020 to examine associations between job demands, work-related hazards and MSS.

METHODS

Through convenience sampling, cross-sectional survey data from 459 workers were collected and analyzed using logistic multiple and binary logistic regression methods. Outcome variables were MSS to the low back, neck/shoulder, and wrist/hand. Predictor variables and MSS measures are based on the Dutch Musculoskeletal Questionnaire.

RESULTS

Increased odds of low back MSS were related to dynamic loads (OR = 2.14), pushing/pulling heavy loads (OR = 1.56), torso bending or twisting (OR = 2.36), bent, stooped, or twisted posture (OR = 2.04), uncomfortable postures (OR = 2.07), repetition (OR = 1.67) and vibrating tools (OR = 1.81). Increased odds of neck/shoulder MSS were related to dynamic loads (OR = 1.83), static loads (OR = 1.24), heavy lifting (OR = 1.50), pushing/pulling heavy loads (OR = 1.68), bending or twisting of the neck (OR = 1.82), twisted neck posture (OR = 1.77) and uncomfortable postures (OR = 1.81). Increased odds of wrist/hand MSS were related to dynamic loads (OR = 2.06), static loads (OR = 1.45), bending or twisting of the wrists/hands (OR = 10.52), extended reaching (OR = 3.05), repetition (OR = 5.25), awkward postures (OR = 4.47), working above shoulder level (OR = 2.47), and vibrating tools (OR = 1.78).

CONCLUSION

Hazards that increased the likelihood of MSS were identified. These hazards should be abated or controlled to prevent MSDs in stone, sand, and gravel mining. More applied research, including ergonomic assessments to further identify hazards that can be controlled or abated, is warranted.

Prevalence of musculoskeletal disorders among dental healthcare providers: A systematic review and meta-analysis

Background: Work-related musculoskeletal disorders (MSD) are common in dentistry due to the prolonged static work involved during patient care, making dental health care personnel vulnerable to musculoskeletal complaints. We aimed to pool the prevalence estimates of MSD among various dental healthcare providers, including dentists, dental students, dental hygienists, and auxiliaries. Methods: A systematic search of five databases was performed (Scopus, Embase, CINAHL, Web of Science, Dentistry & Oral Sciences Source). The studies that reported the prevalence of MSD among dental healthcare workers and those written in English were selected. Screening and data extraction were performed by two review authors independently. Discrepencies were resolved by another review author. Risk of bias assessment was done using a nine-item questionnaire developed by Hoy et al. Pooled estimates were calculated using meta-analysis of proportions (random effects model). Results: Among the 3090 publications screened, 234 publications were included for full-text screening. Meta-analysis was performed for 89 estimates from 88 publications. Females showed significantly higher prevalence [OR = 1.42 (95% CI = 1.09-1.84); I ² = 66.02; N = 32]. The analysis yielded a pooled estimate of 78.4% (95% CI = 74.8-82). The meta-regression showed similar prevalence over the years (Coefficient: 0.001; P-value: 0.762). Conclusions: A high prevalence of MSD was noted among dental healthcare providers, with about seven out of ten having experienced MSD in the past. This emphasizes the need for awareness and adoption of appropriate ergonomic postures by dental healthcare providers from early in their careers to minimize work-related MSD.

A Grounded Theory Study on the Intention to Work While Ill among Workers with Musculoskeletal Disorders: An In-Depth Understanding of Workers' Experiences

BACKGROUND

Frequent short-term sickness absence is prevalent among workers with musculoskeletal disorders (MSDs). This in return leads to poor productivity in organizations and decreased ability to work among workers. Nevertheless, some workers with MSDs still continue to work despite pain and are able to maintain their productivity. Existing literature on attending work while ill is very limited. Understanding the factors influencing workers' attendance to work while having symptoms is crucial to help workers live with their MSD productively and healthily. According to literature on behavior theories, the proximal determinant of behavior is one's intention to engage in that behavior. Thus, this study was conducted to explore the factors that influence the intention to work while ill among workers with MSD.

METHODS

Twenty-one in-depth interviews were conducted using a semi-structured guide according to a grounded theory approach. Workers with MSD were recruited via a purposive and snowballing sampling until data saturation was attained. Data were analyzed by means of thematic analysis using computer software, ATLAS.ti.

RESULTS

Nine major significant themes of factors influencing the intention to work while ill were identified after transcription. From these, a total of six themes were associated with attendance incentives driving workers to attend work while ill (work commitment, work satisfaction, support from colleagues, workplace arrangements, ability to recover at home and ability to manage pain at work) and three themes were linked to attendance requirements (consequences to self, consequences to others and poor acceptance of one's illness for sickness absence by supervisor and colleagues) faced by workers to attend work while ill.

CONCLUSIONS

This study underlines the importance of both positive and negative motivators in influencing the intention to work while ill among workers with MSD. Future research suggests comparing both motivators in terms of work performance to aid more workers to work while ill.

Analysis of occupational stress, burnout, and job satisfaction among dental practitioners

BACKGROUND: Dental practitioners can be prone to stress because of the long working hours, high patient expectations, and work environment. OBJECTIVE: To investigate dimensions of occupational stress among dental practitioners leading to burnout and to model its causality with job satisfaction. METHODS: An analytical cross-sectional study was conducted for five months. A sample of 302 practicing dental practitioners was selected using the consecutive sample technique. This sample included dental practitioners working in clinical and non-clinical departments of public and private sector universities as well as those doing private general practice. A self-administered structured questionnaire based on the Work Stress Questionnaire was sent using Survey Monkey. Descriptive statistics were calculated. Spearman correlation was applied between stress scores and job satisfaction. A Chi-square test was applied to look into the association between stress levels and different categories. Univariate and multivariate analysis was performed. RESULT: The prevalence of overall occupational stress was high among dental practitioners (83.4%). Occupational stress was greatest in females (55.8%), dental practitioners in the private sector (55.7%), and general dental practitioners (GDPs) (47%). The overall prevalence of job satisfaction among dental professionals was 30%. Occupational stress was significantly associated with burnout and job dissatisfaction in dentistry. Stress levels and working hours were statistically and positively associated, whereas the association between stress levels and job satisfaction was inversely and significantly associated. CONCLUSION: The prevalence of occupational stress among dental practitioners was high and the level of job satisfaction was moderate. The model between these variables was well-fitted.

Work Performance, Mood and Sleep Alterations in Home Office Workers during the COVID-19 Pandemic

The sudden burst of the COVID-19 pandemic has changed the work environment in favor of remote working, affecting the perception of work quality, satisfaction and performance. This crisis has also influenced workers’ mood, sleep quality and general perception of everyday life. Our main purpose in this study was to give empirical contributions about home office workers experiencing remote working during the pandemic by assessing mood spectrum variations, sleep disturbances and the general impact of pandemic in everyday life. This cross-sectional study was performed between November and December 2020 through an online questionnaire. Participants were office workers performing remote work from workstations settled at home. The questionnaire investigated sociodemographic characteristics, health factors, perception of remote working, mood spectrum, sleep quality and pandemic context perception. The sample consisted of 94 respondents: 63 women and 31 men; the mean age was 50.4 years. Study population showed great satisfaction for remote working performance and online services for video connections. Only one third of the participants reported higher levels of irritability and loneliness and 16% of women complained of nightmares. Most of participants stated that the pandemic importantly affected daily life (85.1%). Half of female subjects with children <18 years stated that children’s age influenced their work performance. Since the pandemic is still an ongoing issue, the lesson learnt is that local government actions are needed to assist home office workers through tailored programs to support families. Given the central role of women in childcare, female workers would mainly benefit from social support accordingly to their parental tasks and remote work organization.

The relationship between occupational stress, mental health and work ability of coal chemical workers in Xinjiang

OBJECTIVE

To understand the current working ability of coal chemical workers in Xinjiang, and analyze the impact of occupational stress, mental disorders, and their interaction on work ability. To provide a scientific basis for improving the working ability and quality of life of coal chemical workers.

METHODS

In this study, a stratified random sampling method was used to conduct a questionnaire survey of 1,400 workers in six coal mining enterprises from June to December 2019. The Effort-Reward Imbalance Questionnaire (ERI), the Symptoms Checklist 90 (SCL-90), and the Work Ability Index Scale (WAI) were used to evaluate the level of occupational stress, mental disorders, and the ability to work as coal chemical workers.

RESULTS

The results showed that WAI scores had statistically significant differences between gender, age, length of service, shift, education, marital status, and monthly income (P < 0.05). The ability to work and its dimensions were inversely correlated with occupational stress, and mental disorders (P < 0.001). Occupational stress and mental disorders are risk factors affecting the ability to work. Workers with high occupational stress^* mental disorders (OR = 10.666, 95% CI: 6.443-17.658) are 10.666 times more likely to be at risk for developing poor work ability than low occupational stress^* no mental disorders. Structural equation models show that occupational stress and mental health conditions had a direct impact on work ability, and mental health conditions were the mediators of the relationship between occupational stress and work ability.

CONCLUSION

Occupational stress, mental disorders, and their interaction are risk factors affecting the ability of coal chemical workers to work. Occupational stress can indirectly affect the ability to work through mental health conditions.

Mitochondrial Function as Related to Psychological Distress in Health Care Professionals

OBJECTIVE

The present study evaluated the association of psychological distress and radiation exposure as a work-related stressor with mitochondrial function in health care professionals.

METHODS

Health care professionals at a regional hospital in Italy were evaluated for physical health and psychological measures using self-report questionnaires (n = 41; mean age = 47.6 [13.1] years; 66% women). In a second sample, individuals exposed to elevated levels of ionizing radiation (IR; likely effective dose exceeding 6 mSv/y; n = 63, mean age = 45.8 [8.8] years; 62% women) were compared with health care workers with low IR (n = 57; mean age = 47.2 [9.5] years; 65% women) because exposure to a toxic agent might act as a (work-related) stressor. Associations were examined between psychological factors (12-item General Health Questionnaire, Perceived Stress Scale), work ability (Work Ability Index), and IR exposure at the workplace with markers of mitochondrial function, including mitochondrial redox activity, mitochondrial membrane potential, mitochondrial DNA (mtDNA) copy number, biogenesis, and mtDNA damage response measured from peripheral blood mononuclear cells.

RESULTS

All participants were in good physical health. Individuals reporting high levels of psychological distress showed lower mitochondrial biogenesis as indicated by peroxisome proliferator-activated receptor-γ coactivator 1-α and lower nuclear factor erythroid 2-related factor 2 (NRF2) expression (2.5 [1.0] versus 1.0 [0.9] relative expression [rel exp], p = .035, and 31.5 [5.0] versus 19.4 [6.9] rel exp, p = .013, respectively). However, exposure to toxic agents (IR) was primarily associated with mitochondrial metabolism and reduced mtDNA integrity. Participants with IR exposure displayed higher mitochondrial redox activity (4480 [1202] mean fluorescence intensity [MFI]/min versus 3376 [983] MFI/min, p < .001) and lower mitochondrial membrane potential (0.89 [0.09] MFI versus 0.95 [0.11] MFI, p = .001), and reduced mtDNA integrity (1.18 [0.21] rel exp versus 3.48 [1.57] rel exp, p < .001) compared with nonexposed individuals.

CONCLUSIONS

This study supports the notion that psychological distress and potential stressors related to toxic agents might influence various aspects of mitochondrial biology, and that chronic stress exposure can lead to molecular and functional recalibrations among mitochondria.

Prevention of work-related musculoskeletal disorders among dental professionals: A scoping review

BACKGROUND

Musculoskeletal disorders (MSDs) are highly prevalent among dental professionals. Studies examining the prevention of dental work-related MSDs have been completed globally.

OBJECTIVE

To identify and evaluate the available evidence regarding MSD prevention in dental practice, and to identify knowledge gaps.

METHODS

An electronic search was conducted across multiple scientific databases. Identified articles were assessed according to inclusion/exclusion criteria. Systematic reviews, interventions and published expert opinion were included.

RESULTS

Five systematic reviews, 27 intervention studies and 21 expert opinion articles were included. There was overall consensus that use of ergonomic equipment is beneficial in MSD prevention. Knowledge gaps identified included: a lack of systematic reviews on the role of exercise and therapy in MSD prevention; a lack of high-quality intervention studies; a lack of research in general outside of ergonomic equipment use. Expert opinion articles have been published despite a lack of dental-specific research.

CONCLUSIONS

Whilst more robust research is required, current evidence supports the use of optical enhancement, saddle chairs, and wide-diameter silicone-handled instruments in MSD prevention. Knowledge gaps were identified relating to the use of exercise, therapy, and education in the prevention of dental work-related MSDs. Further research is required, specifically high-quality intervention studies.

Online supervised versus workplace corrective exercises for upper crossed syndrome: a protocol for a randomized controlled trial

Background and objective

Musculoskeletal disorders (MSDs) including upper crossed syndrome (UCS) are considered as the leading cause of work-related issues worldwide among office workers. Therefore, the present study aims to evaluate the effect of workplace-based versus online-supervised home-based corrective exercises among office workers with UCS.

Methods and design

To this end, 45 subjects within the age range of 30–45 years are randomly assigned to three groups in the present parallel-group, randomized control trial using a pretest-posttest design. These groups include the subjects who receive online-supervised exercise and workplace exercise containing three sessions of intervention for 8 weeks and the control group receives no intervention while performing routine activities. The primary outcome variables are neck-shoulder pain (NSP) and consequent sick leave due to NSP, followed by alignment, workability, and the surface electromyography of upper, middle, and lower trapezius (UT, MT, and LT), sternocleidomastoid (SCM), and serratus anterior (SA) as the secondary variables.

Discussion

The present study seeks to assess the effect of workplace versus online-supervised corrective exercise interventions among 45 office workers suffering from UCS. It is expected to improve and reduce the related symptoms including postural malalignment and imbalance muscles after 8 weeks of corrective exercises. If effective, the findings may lead to adherence and work performance among the office workers, and individuals subjected to UCS can use the benefits of an online-supervised intervention. In addition, the findings may be useful in different workplaces as the evidence for employers to benefit from the reduction in the related costs and side effects of work-related neck/shoulder disorders including work disability, productivity loss, time expense, social insurance, work absenteeism, and treatment costs. Finally, clinicians and corrective exercise therapists can consider it as a clinical based-evidence intervention for their further actions.

Psychometric Properties of the Work Ability Index in Health Centre Workers in Spain

The aim of the present study is to analyse the psychometric properties of the work ability index (WAI) within a sample of Spanish health centre workers. The WAI was translated into Spanish using transcultural and forward–backward translation processes and administered to 1184 Spanish health centre workers. Internal consistency, predictive validity, and discriminative ability were examined. Exploratory factor analysis, via principal components analysis and confirmatory factor analysis, determined the most appropriate questionnaire structure. All indices in relation to predictive validity and reliability were acceptable. Exploratory factor analysis supported validity of the one-factor structure, however, confirmatory factor analysis suggested better properties in relation to a two-factor structure (χ² = 59.52; CFI = 0.98; TLI = 0.96; RMSEA = 0.06). Items 3, 4, and 5 loaded onto factor one, and items 1, 2, 6, and 7 loaded onto factor two. The two factors could be broadly described as “subjectively estimated work ability” and “ill-health-related ability”. The WAI is valid and reliable when administered to health centre workers in Spain. In contrast to that suggested by studies conducted in other countries, future research and practical application with similar respondents and settings should proceed using the two-factor structure.

Occupational Stress among Dental Professionals

Stress at the work place was declared by the World Health Organization as a worldwide epidemic. The stress caused by work appears when the balance between one’s own possibilities and the environment demands is disturbed, which leads to a poor mental state. The fact is that the majority of dentists find they are under constant stress, which is caused by the nature of dental work. Literature describes dentistry as an extremely stressful profession. The main stressors include the tendency toward technical perfection, the causation of pain in patients, the lack of patient cooperation during dental treatment, the failure to maintain the given appointments. Adequate education and preparation, even during dental studies, non-neglect of symptoms and difficulties at the work place, adequate and timely response to the identification of the cause and its elimination or balancing, have a key role in solving this great problem in modern dentistry.

Drivers of productivity: Being physically active increases yet sedentary bouts and lack of sleep decrease work ability

Physical behavior (ie, physical activity, sedentary behavior, and sleep) is a crucial lifestyle factor for preventing and managing diseases across the lifespan. However, less is known about potential work-related psychological and cognitive outcomes such as productivity. The present study examined within-person associations between physical behavior and self-perceived work ability. To investigate the degree to which physical behavior parameters influence self-perceived work ability in everyday life, we conducted an Ambulatory Assessment study in 103 university students over 5 days. Physical behavior was assessed continuously via a multi-sensor system. Self-perceived work ability was assessed repeatedly up to six times per day on smartphones. We employed multilevel modeling to analyze the within-person effects of physical behavior on self-perceived work ability. Physical activity intensity (MET) (β = 0.15 ± 0.06, t = 2.59, p = 0.012) and sit-to-stand transitions (β = 0.07 ± 0.03, t = 2.44, p = 0.015) were positively associated with self-perceived work ability. Sedentary bouts (≥20 min) (β = -0.21 ± 0.08, t = -2.74, p = 0.006) and deviation from a recommended sleep duration (ie, 8 h) (β = -0.1 ± 0.04, t = -2.38, p = 0.018) were negatively associated with self-perceived work ability. Exploratory analyses supported the robustness of our findings by comparing various time frames. Total sedentary time and sleep quality were not associated with self-perceived work ability. Regular sleep durations, breaking up sedentary time through sit-to-stand transitions, and higher intensities of physical activity may be important for the regulation of self-perceived work ability in university students' daily lives.

Dentists working conditions - factors associated with perceived workload

BACKGROUND

Dentists are often exposed to occupational health hazards such as stress, high workload, and ergonomic and mental strain. However, there are limited studies focussing on occupational health and factors associated with working conditions. The aim of this study was to identify possible gender differences and factors associated with a high workload.

METHOD

The study population comprised of 187 dentists (123 women and 64 men) who had been working between 5 and 12 years. All participants completed a questionnaire regarding perceived workload and different working conditions. In the logistic regression analyses, gender and employment (employee or employer/manger), influence over work, social support, ergonomics, and working hours were used as independent covariates.

RESULTS

Poor satisfaction with ergonomic conditions and low influence on the work situation were reported by 40 and 47% of the participants, respectively. Female dentists were more often employees, reported lower influence over work situation, and more often worked part-time compared to male dentists. Those who reported a high workload significantly more often experienced that they had low influence over work, low levels of social support, and were not satisfied with ergonomic working conditions.

CONCLUSION

Dentists with low influence over work, low levels of social support, and who were unsatisfied with the ergonomic conditions reported higher levels of workload. The dentists experienced a similar workload, regardless of employment and gender. Preventive actions at the workplace in order to maintain a moderate workload promote both individual and organizational measures, to minimize the risk of poor occupational health.

Effectiveness of combined aerobic exercise and neck-specific exercise compared to neck-specific exercise alone on work ability in neck pain patients: a secondary analysis of data from a randomized controlled trial

OBJECTIVE

To compare the effect of combined aerobic exercise (AE) and neck-specific exercise to neck-specific exercise alone on the work ability of individuals complaining of neck pain.

METHOD

Secondary analysis of data from a previous randomized controlled trial was conducted to compare AE and neck-specific exercise (AE group, n = 69) to neck-specific exercise alone (control group, n = 70). The Work Ability Index (WAI) was administered after the 6-week intervention, and Global Rating of Change (GROC) was assessed after the 6-week intervention and at 12- and 24-week follow-ups.

RESULTS

Repeated-measure analyses of variance between groups indicated a significant time × group interaction on the GROC at 12- and 24-week follow-ups. The AE group showed better improvement on the GROC (mean ± SD) from 6 to 24 weeks than controls: 4.7(± 0.12) to 5.3 (± 0.13) vs. 4.4 (± 0.13) to 4.1(± 0.13), respectively, (P < 0.001). There was a significant group × time interaction on the WAI (P < 0.001): the AE group showed better improvement (mean ± SD) from baseline to 6-weeks than controls: 34.9 (± 4.4) to 39.2 (± 3.6) vs. 34.4 (± 4.9) to 35.8 (± 4.9), respectively, (P < 0.001). Work ability of participants with poor/moderate baseline scores improved more (P < 0.001) than those with good/excellent baseline scores (P = 0.48).

CONCLUSIONS

Combining moderate AE and neck-specific exercise improved the work ability of patients with NP more than neck-specific exercise alone. The combination should be recommended in health promotion programs, particularly for workers with low baseline work ability.

[Evaluation of dentists regulatory systems stress during the provision of dental care according to pulse oximetry data]

OBJECTIVE

To evaluate the status of individual hemodynamic parameters (HR) and respiratory indicators of dentists performing local anesthesia. Material and methods. In the period from April 2019 to December 2019 the determination of heart rate (Heart rate) and blood saturation at 120 doctors aged 25-55 years was performed. The value of blood saturation by non-invasive pulse oximeter technique: SpO₂ measurement range 0-99%; heart rate range 18-300 beats per minute. The limit of 95-98% was considered normal. However, we consider it correct to note the introduction of an error of 0.1% due to the constant wearing of a dentist's tight polymer mask. All subjects were preliminarily determined by Robergs-Landvere formula: maximum heart rate (MF)=205.8-(0.685·age).

RESULTS

Maximum HR limits for the groups of subjects were 185.6±3.1 beats per minute in the first group; 178.7±3.1 beats per minute in the second group; 171.5±3.4 beats per minute in the third group. In all groups the tendency to decrease blood saturation in case of pain appearance in patients during treatment against the background of block anesthesia, as well as during anesthesia on the mandible was determined. The definition of SpO₂ showed a slight downward trend in blood saturation when pain occurs within normal parameters. Thus, the limit of changes in the index against the background of performed local anesthesia on the mandible was 95.2-96.1% and 96.3-96.6% on the maxilla.

CONCLUSION

Measurement of arterial oxygen saturation in dentists showed a tendency for a slight decrease in this indicator within the normal range when the patient developed pain. Thus, the limit of changes in the indicator against the background of local anesthesia on the lower jaw was 95.2-96.1%, on the upper jaw - 96.3-96.6%.

Prevalence of multisite pain and association with work ability - Cross-sectional study

BACKGROUND

Multisite pain (MSP) has been studied among the working population because it is associated with reduced work ability. In Brazil, studies have investigated pain without addressing MSP and its interference with work ability.

OBJECTIVE

To evaluate the prevalence of MSP among Brazilian workers from different occupations and to associate MSP with work ability.

METHODS

Participants in the BRAzilian eValuation of Occupational health (BRAVO) database were analysed. The BRAVO database contains information about personal data, musculoskeletal symptoms (Nordic Musculoskeletal Questionnaire), occupational stress (Job Content Questionnaire) and work ability (Work Ability Index). The studies were approved by the Ethics Committee and all participants signed an informed consent form. Data were analysed using logistic and linear regression. Sex, age, comorbidities (hypertension, mild emotional disorder and gastritis), type of work (blue and white-collar) and occupational stress were included as covariates of the regression models.

RESULTS

The prevalence of MSP was 58% (95% CI = 53-62%) among the total sample, 57% (95% CI = 52-62%) in white-collar and 53% (95% CI = 40-66%) among blue-collar workers. The presence of MSP increases the chance of low work ability between 1.8 and 5.1 times. A dose-response relationship was found, with the increase in each pain site causing a reduction of 0.9-1.2 points in the work ability index.

CONCLUSIONS

MSP is highly prevalent among Brazilian workers and should be addressed due to its impact on reducing work ability.

Evaluation of the Cervical Physiotherapeutic Treatment Needs, Work Ergonomics, and Necessity for Physical Activity Among Students of Dentistry at a Medical University. A Pilot Study

INTRODUCTION

A lot of general dental practitioners suffer from job-related health problems. They are more prone to numerous different physical and psycho-emotional triggers that aggravate their working conditions.

THE AIM

The aim of the study was to evaluate cervical physiotherapeutic treatment needs, daily ergonomic habits and the necessity for physical activity among students of dentistry at a medical university.

MATERIALS AND METHODS

112 generally healthy dentistry students (73 women, 39 men) were enrolled for the study. The age range was 20-32, with an average of 22.88 ± 2.7. The study included subjects in their second to fifth year of studies. The survey was conducted with respect to the questionnaires about possible physiotherapeutic treatments, physical activities, imaging tests and diagnoses as well as statements regarding the respondents' knowledge and ergonomics habits. To estimate the association between the risk factor and neck disability as well as chronic pain, the Neck Disability Index, Perceived Stress Scale and the Graded Chronic Pain Scale were additionally applied.

RESULTS

35.71% of dentistry students had undergo physiotherapy in the preceding year. 26.79% of the respondents declared that they underwent rehabilitation on a regular basis. The most common reasons for treatment were complaints of the cervical (7.14%), lumbar (3.57%), and thoracic spine (1.79%) as well as a combination of these symptoms. 6.25% of the subjects had started rehabilitation due to muscle relaxation. 34.82% of the study participants did not do any physical activity. Females exercised more often than males (p = 0.02; 1-β = 0.65). Therapeutic exercises contributed to the improvement of well-being of 56% of students. 64.29% of the respondents chose a sitting position during pre-clinical and clinical classes and 26.79% of the subjects worked in sitting and standing postures.

CONCLUSION

26.79% of dentistry students required periodic therapeutic rehabilitation. 34.82% of the respondents were advised to implement systematic physical activity. Due to professional conditions, dental students are exposed to an early cervical spine disorders. The main factor influencing an early onset of such dysfunctions is increased stress level. An average level of pro-health awareness may be the reason for elevated cost of rehabilitation among this group of patients.

Is low-back pain a limiting factor for senior workers with high physical work demands? A cross-sectional study

BACKGROUND

Low-back pain (LBP) is highly prevalent among senior workers and may affect work ability, especially among those with hard physical work. This study determined the joint association of LBP intensity and physical work demands with work limitiations due to pain in senior workers.

METHODS

In the SeniorWorkingLife study (2018), 11,738 senior workers (≥50 years) replied to questions about physical work demands, LBP intensity, and work limitations due to pain. Using logistic regression analyses and controlling for potential confounders, associations between the physical work demands and LBP intensity (interaction) with work limitiations due to pain (outcome) was modeled.

RESULTS

Higher LBP intensity, as well as higher physical work demands, significantly increased the odds of experiencing work limitiations due to pain, and these two factors interacted with each other (p < 0.0001). In analyses stratified for LBP intensity, higher physical work demands gradually increased the odds of experiencing work limitiations due to pain.

CONCLUSIONS

Senior workers with a combination of physically demanding work and LBP are more affected by their pain during everyday work tasks compared to workers with similar LBP-intensity in sedentary occupations. Accommodation of work demands seems especially relevant for this group of workers.

A Novel Fabrication of Dose-Dependent Injectable Curcumin Biocomposite Hydrogel System Anesthetic Delivery Method for Care and Management of Musculoskeletal Pain

Chronic musculoskeletal pain has biological, psychological, and social components. In this article, we have demonstrated the easily injectable nanocomposite carrier for the treatment of chronic musculoskeletal pain. Briefly, the curcumin (Cur) loaded with lipid nanocapsules (LNCs; Cur@LNCs) using the phase invasion method. The synthesized Cur@LNCs were characterized by using scanning electron microscopy, transmittance electron microscopy, and the size of the fabricated nanoparticles confirmed by dynamic light scattering analysis. The synthesized Cur@LNC injectable hydrogel shows excellent results in vivo in the rat model. We have examined the efficiency of the chronic constriction injury in the rat model and induced the pain using thermal paw withdrawal latency. The injectable hydrogels Cur@LNCs display a remarkable reduction in pain 7 days post administrations compared to the untreated group animals. This work could establish the preclinical candidate of the neuropathic pain response in the future.

Hospital Staff Report It Is Not Burnout, but a Normal Stress Reaction to an Uncongenial Work Environment: Findings from a Qualitative Study

(1) Background: The issue of burnout in healthcare staff is frequently discussed in relation to occupational health. In this paper, we report healthcare staff experiences of stress and burnout. (2) Methods: In total, 72 healthcare staff were interviewed from psychiatry, surgery, and emergency departments at an Australian public health service. The sample included doctors, nurses, allied health professionals, administrators, and front-line managers. Interview transcripts were thematically analyzed, with participant experiences interpreted against descriptors of burnout in Maslach's Burnout Inventory and the International Statistical Classification of Diseases and Related Health Problems (ICD-11). (3) Results: Staff experiences closely matched the ICD-11 description of stress associated with working in an uncongenial workplace, with few reported experiences which matched the ICD-11 descriptors of burnout. (4) Conclusion: Uncongenial workplaces in public health services contribute to healthcare staff stress. While previous approaches have focused on biomedical assistance for individuals, our findings suggest that occupational health approaches to addressing health care staff stress need greater focus on the workplace as a social determinant of health. This finding is significant as organizational remedies to uncongenial stress are quite different from remedies to burnout.

Mediating Factors for the Relationship between Stress and Work Ability over Time in Young Adults

Stress can affect work ability. The aim of this study was to identify how this pathway is mediated over time in young adults. Participants of the Work Ability in Young Adults cohort were selected. A theoretical framework was built, which lead to a statistical model. Selected dimensions of mediators were recovery, work demands affecting private life, feelings of control over private life, and physical activity in leisure time. A quadruple serial mediation model was built with four mediators. The total effect of stress on work ability was -0.3955, 95% CI [-0.4764, -0.3146]. The total indirect effect amounted to 81% with an effect of -0.3182, 95% CI [-0.3750, -0.2642]. The relationship between stress and Work Ability Score five years later in young adults was mediated by stress five years later, work demands affecting private life, feelings of control over private life and feeling well-rested upon waking. These results indicate that work demands affecting private life and feelings of control over private life are important mediators of the relationship between stress and work ability in young adults. A well-balanced relationship between work and private life can counteract the influence of stress on work ability in this age group.

Ergonomic risk exposure and work ability among young dental professionals in China: A cross-sectional study

BACKGROUND

Exposure to high ergonomic risk resulted in an increasing prevalence of musculoskeletal disorders among dental professional. However, little is known about the high exposure risk impact on work ability among dental professionals.

OBJECTIVE

We conducted a cross-sectional study to examine the association between ergonomic risk exposure and work ability among young dental professionals in their early careers.

METHODS

A total of 230 dental professionals including dentists, dental assistants, and nurses were clustered sampled from three hospitals in Guangzhou, south of China. We used the Quick Ergonomic Check (QEC) to assess participants' ergonomic risk exposure and Work Ability Index (WAI) to evaluate their work ability. Demographics and other factors related with WAI were also included in the data collection. Multiple linear regression was applied to analyze the association between ergonomic exposure scores and WAI.

RESULTS

A total of 218 participants (94.8%) had valid data and consent forms. The participants' average WAI was 39.6, of which the poor and moderate WAI composed 31%. High and very high ergonomic risk exposure level was 45.9% for the neck and 21.1% for the wrist/hand. In general, WAI decreased with higher ergonomic exposure level. With adjustment of other potential risk factors, the ergonomic scores for wrist/hand and total scores for the whole body were significantly associated with the decreased WAI.

CONCLUSION

High ergonomic risk exposure might risk in reducing work ability among young dental professionals. Intervention measures toward ergonomic risk should be taken to prevent WAI from decreasing in their early careers.
