Relationship between pain catastrophizing and pain self-efficacy and presenteeism in workers: a cross-sectional-study focusing on gender differences

Presenteeism has been noted to be associated with cognitive factors of pain, such as pain catastrophizing (PC) and pain self-efficacy (PS). Pain perception differs by gender, so it is important to consider gender differences when examining the association between cognitive factors of pain and presenteeism. This study aimed to examine the association between presenteeism and cognitive factors of pain, taking gender differences into account. A cross-sectional survey of 305 workers was conducted using a self-administered questionnaire that included items on pain status, PC, PS, and work performance. Multiple logistic regression analysis was used to test whether PC and PS independently influence presenteeism, separately for men and women. Logistic regression analysis showed that PC was extracted in men, and the group with severe PC had higher odds of presenteeism (odds ratio 6.56, 95% confidence interval [CI] 1.83-23.40). Contrarily, PS was extracted in women, with higher odds of presenteeism in the moderate (odds ratio 2.54, 95% CI 1.01-6.39) and low (odds ratio 5.43, 95% CI 1.31-22.50) PS groups than in the high PS. This study showed that the cognitive factors of pain related to presenteeism may differ by gender.

Physical Therapist-Led Initiatives for the Prevention and Improvement of Chronic Pain Among Workers: A Case Study of Hosting Workshops Based on Survey Results in a Corporate Setting

Industrial physical therapy (IPT) interventions by physical therapists can enhance labor productivity. However, in Japan, there is a scarcity of case studies involving corporate visits, questionnaire-based data, and insights into corporate demands. Addressing this gap is vital for improving presenteeism related to chronic pain and increasing employees' health literacy, thereby advancing corporate health management. This case study evaluates the effectiveness of a workshop aimed at preventing and reducing chronic pain among employees in the Development Department of Company A, an information technology (IT) firm. The research employed pre- and post-survey questionnaires, workshop interventions, and meetings with corporate management to assess the current state of musculoskeletal chronic pain and productivity losses and to verify the intervention's effectiveness. Approximately 50 participants attended the workshop in person, while around 30 participated online, totaling 80 attendees. A total of 56 (51 men and 5 women) individuals responded to the pre-workshop questionnaire, and 28 responded to the post-workshop questionnaire. The age distribution of the 56 pre-survey respondents was as follows: 9 in their twenties, 13 in their thirties, 22 in their forties, and 12 aged 50 and older. Preliminary survey results showed that 55.4% of participants experienced chronic pain in at least one body part. The average presenteeism value was 82.8% (standard deviation = 16.8). It was also found that literacy regarding appropriate pain management strategies was low. An independent t-test comparing literacy scores based on the presence or absence of pain showed no significant differences (p = 0.34). Additionally, a one-way ANOVA conducted to examine differences across four age groups revealed no significant differences (F = 0.934, p = 0.431). Results from the post-workshop questionnaires indicated that more than 70% of the employees experienced an increase in understanding and satisfaction, with positive feedback on the improvement of knowledge about chronic pain mechanisms and posture. However, there were also requests for more interactive communication and a desire to learn more about specific care methods, suggesting the need to provide interventions tailored to appropriate stages of preventive medicine.

Daily Associations Between Presenteeism and Health-Related Factors Among Office Workers: An Ecological Momentary Assessment Approach

OBJECTIVE

The study examined daily associations between presenteeism and health-related factors among office workers using ecological momentary assessment (EMA).

METHODS

Diurnal mood and physical symptoms were repeatedly recorded over 2 weeks with EMA. Daily work performance (WP) was also recorded. Recalled WP and baseline health conditions were assessed via questionnaires. Daily sleep was assessed using actigraphy. Reliability between recalled and daily WP was compared. Hierarchical linear modeling (HLM) was used to analyze the effects of sleep, mood, and physical symptoms on daily WP.

RESULTS

Weak yet significant agreement was found between recalled and daily WP, with EMA capturing occasional declines in performance overlooked by recalled assessments. HLM indicated that longer sleep, reduced depressive mood, and decreased shoulder stiffness were significantly associated with increased daily WP.

CONCLUSIONS

These factors are associated with daily fluctuations in presenteeism, suggesting potential targets of intervention.

Work-related musculoskeletal pain among physical therapists: a cross-sectional study in Kyoto and Shiga prefectures, Japan

OBJECTIVES

This study aimed to determine the actual working conditions and prevalence of musculoskeletal pain among physical therapists in Japan, and the risk factors associated with low back pain (LBP) and upper limb pain (ULP).

METHODS

A cross-sectional study of physical therapists in the Kyoto and Shiga prefectures was conducted using a self-administered questionnaire. The survey contents included questions regarding personal, work-related, and musculoskeletal pain factors. Logistic regression models were used to analyze factors associated with LBP and ULP.

RESULTS

Responses from 1479 participants were included in the analyses. The prevalence of LBP at the time of the survey and in the past year was 40.1% and 74.3% in females, and 37.8% and 69.9% in males, respectively. The prevalence of ULP was 34.8% and 64.2% in females, and 27.2% and 53.3% in males. The numbers of patients who performed manual therapy per day, worked using a fixed-height bed, performed manual therapy, had job dissatisfaction and stress, were over 40 years old, and slept less than 6 hours were associated with LBP and ULP. Assistance task was a risk factor only for LBP, and female sex a risk factor only for ULP.

CONCLUSIONS

The prevalence of LBP and ULP among physical therapists in Japan was as high as that in nurses and care workers. Work-related factors associated with LBP and ULP were identified among physical therapists. Thus, to prevent work-related musculoskeletal disorders, measures to reduce the physical burden from the perspective of occupational health are required.

Relationship between impaired work function and coping behaviors in workers with low back pain

OBJECTIVES

The aim of the present study was to clarify the relationship between work functional impairment levels and three coping behaviors of workers with low back pain, which were about seeking medical attention, taking over-the-counter drugs, and taking self-care.

METHODS

We conducted a cross-sectional study on 14 Japanese companies in 2016. Work function impairment was measured using the Work Functioning Impairment Scale. Logistic regression analyses were conducted for the three coping behaviors and odds ratios (ORs) calculated for work functional impairment levels.

RESULTS

We analyzed 2232 subjects; 226 were women and 790 worked on production lines. 688 workers had sought medical attention, 436 had taken over-the-counter medication, and 1225 had engaged in self-care. Those seeking medical attention were associated with severe work function impairment compared with no work function impairment (adjusted OR = 2.84, 95% confidence interval: 1.82-4.45, p < .001). We observed a trend for the association between over-the-counter drug use with high levels of work function impairment (adjusted OR: 1.19 for low, 1.35 for moderate, 1.65 for severe). There was no apparent relationship between self-care and the degree of work functional impairment.

CONCLUSION

In workers with low back pain, severe work functional impairment may promote medical attention and over-the-counter medication use, but it would not encourage self-care, such as stretching or exercise. Therefore, workplaces need to provide special support to help them take care of themselves. Therefore, it is desirable to provide good support for self-care in the workplace.

The Relationship Between Fear-avoidance Beliefs in Employees with Chronic Musculoskeletal Pain and Work Productivity: A Longitudinal Study

This study aimed to identify risk factors for chronic musculoskeletal pain (CMSP) and sought to examine the effect of fear-avoidance beliefs (FABs) on work productivity in workers with CMSP. We performed a longitudinal study using self-administered questionnaires given to employees in three different industries between April 2016 and March 2017. The questionnaire concerned background characteristics, work-related factors and musculoskeletal pain, the Work Functioning Impairment Scale (WFun), and the Japanese version of the Tampa Scale for Kinesiophobia (TSK-J). We performed logistic regression analysis to evaluate factors affecting CMSP and a multi-way analysis of variance to analyze the relationship between FABs and CMSP and the effect of FABs on the ability to function at work. Age (odds ratio [OR] = 1.02, 95% confidence interval [CI]: 1.00-1.03), mean working hours (OR = 1.18, 95% CI: 1.04-1.33), and changes in working hours (OR = 1.18, 95% CI: 1.02-1.37) were significantly associated with CMSP. Regarding FABs, we found that the stronger the FAB, the greater the WFun score, and that an increase in FABs resulted in a significant increase in WFun scores. This study demonstrated that long or increased working hours may be risk factors for CMSP, and that stronger FABs in those with CMSP are associated with decreased ability to function at work. In addition, measures to reduce FABs in workers with CMSP may be effective.
