Relationship between occupational stress and presenteeism status among workers in small and medium-sized enterprises.

This study aimed to identify characteristics of workers experiencing health problems without a decline in labor productivity to address presenteeism. A cross-sectional analysis was conducted on 554 workers in Japan, with a median age of 43 years. Participants reported any health problems in the past month, along with job stressors, stress responses, social support, and job and life satisfaction using the Brief Job Stress Questionnaire. They were categorized into three groups: "no symptoms," "pre-presenteeism" (health problems without work impact), and "presenteeism" (health problems with work impact). Results showed that 30.1% were in "prepresenteeism" and 52.0% in "presenteeism." Stress responses and social support were linked to both "pre-presenteeism" and "presenteeism," while job stressors and job and life satisfaction were only associated with "presenteeism." These findings offer insights for preventing presenteeism.

Association between different types of physical activity and occupational stress in Japanese workers: a cross-sectional study.

This cross-sectional study investigated the association between different types of physical activity (PA) and occupational psychological and physical stress responses among workers in Japan. Stress responses were assessed using the Brief Job Stress Questionnaire. Work-related PA (time spent sitting, sitting bouts, standing, walking, engaging in heavy labor, and moderate-to-vigorous PA [MVPA]) and exercise-based PA (frequencies [times/week] of flexibility and muscle-strengthening activity, and walking) were measured using a questionnaire. Multiple linear regression was performed to examine the association between each type of PA and stress responses. Participants who engaged in >108 min/day of work-related MVPA exhibited a statistically significant association with higher psychological stress responses when compared to those who engaged in 0-42 min/day of work-related MVPA. For exercise-based PA, participants who engaged in flexibility activity or walking five or more times/week, or muscle-strengthening activity one to three times/week, demonstrated significantly lower psychological stress responses compared to those who did not exercise. Participants who engaged in flexibility activity five or more times/week demonstrated significantly lower physical stress responses compared to those who did not exercise. This study suggests that work-related MVPA is associated with higher psychological stress responses, while exercise-based PA is associated with lower psychological or physical stress responses.

Combined associations of regular exercise and work-related moderate-to-vigorous physical activity with occupational stress responses: a cross-sectional study.

Objective: The association between work-related moderate-to-vigorous physical activity (MVPA) and higher levels of stress response is recognized, but whether this association is moderated by regular exercise remains unclear. This cross-sectional study investigated whether exercise-based physical activity (PA) associates with lower levels of stress responses moderated by work-related MVPA. Methods: The study participants comprised 863 workers from 35 small and medium-sized enterprises in Shimane prefecture, Japan, collected through convenient sampling from April 2021 to August 2022. The Brief Job Stress Questionnaire was used to assess stress responses. Work-related MVPA and exercise-based PA were measured using questionnaires. Multiple linear regression was used to analyze the combined variables of work-related MVPA and exercise-based PA. The reference group had no weekly exercise-based PA and >60 min of work-related MVPA. Results: When work-related MVPA exceeded 60 min/day, flexibility activity or walking for ≥5 days/week (B = -3.53, 95% CI = -5.96, -1.11; B = -2.53, 95% CI = -4.90, -0.16) and muscle-strengthening activity 1-3 times/week (B = -3.52, 95% CI = -6.91, -0.12) were significantly associated with lower psychological stress response. Flexibility activity (B = -1.74, 95% CI = -3.01, -0.46) showed a similar link with physical stress response. When work-related MVPA was below 60 min/day, flexibility activity (B = -3.23, 95% CI = -6.01, -0.44; B = -3.29, 95% CI = -5.94, -0.63) or walking (B = -4.03, 95% CI = -6.62, -1.45; B = -3.10, 95% CI = -5.76, -0.44) practice 1-4 times/week and ≥5 times/week was significantly associated with lower psychological stress response. Conclusion: Exercise-based PA greatly and consistently associates with a lower level of stress responses moderated by work-related MVPA.

Environmental Factors Affecting Cognitive Function among Community-Dwelling Older Adults: A Longitudinal Study.

Although neighborhood environmental factors have been found to be associated with cognitive decline, few longitudinal studies have focused on their effect on older adults living in rural areas. This longitudinal study aimed to investigate the role of neighborhood environmental factors in cognitive decline among rural older adults. The data of 485 older adults aged ≥60 years who were living in Unnan City in Japan and had participated in two surveys conducted between 2014 and 2018 were analyzed. Cognitive function was assessed using the Cognitive Assessment for Dementia, iPad version 2. Elevation, hilliness, residential density, and proximity to a community center were determined using geographic information system. We applied a generalized estimating equation with odds ratios (OR) and 95% confidence intervals (CIs) of cognitive decline in the quartiles of neighborhood environmental factors. A total of 56 (11.6%) participants demonstrated a decrease in cognitive function at follow up. Elevation (adjusted OR 2.58, 95% CI (1.39, 4.77) for Q4 vs. Q1) and hilliness (adjusted OR 1.93, 95% CI (1.03, 3.63) for Q4 vs. Q1) were associated with a higher likelihood of cognitive decline. The second quartiles of residential density showed significantly lower likelihoods of cognitive decline compared with the first quartiles (adjusted OR 0.36, 95% CI (0.19, 0.71) for Q2 vs. Q1). Thus, an elevated hilly environment and residential density predicted cognitive decline among rural older adults.
