The Association between Working Posture and Workers' Depression.

Area of Science:

• Occupational Health
• Mental Health Research
• Epidemiology

Background:

• While physical health effects of working posture are well-studied, the link to mental health remains under-researched.
• Worker mental health is critical, yet the impact of workplace physical demands is often overlooked.
• Previous research has not sufficiently explored the relationship between specific working postures and depression.

Purpose of the Study:

• To investigate the association between various working postures and depression among a large worker population.
• To identify specific occupational postures and related factors contributing to depression in the workforce.
• To provide evidence for interventions aimed at mitigating mental health risks associated with workplace physical demands.

Main Methods:

• Analysis of data from the 5th Korean Working Conditions Survey, involving 49,877 workers.
• Utilized multiple logistic regression to identify variables associated with depression.
• Examined associations between working postures (e.g., tiring positions, standing, sitting) and depression.

Main Results:

• Several working postures, including tiring/painful positions, lifting, prolonged standing, and sitting, were significantly associated with depression.
• Musculoskeletal pain (back, neck, shoulder, arm, hip, leg, knee, foot), occupation type, and job satisfaction also correlated with depression.
• Improper or prolonged working postures, especially those causing pain, showed a notable association with workers' depression.

Conclusions:

• Working posture is demonstrably linked to depression in workers.
• Occupational factors like musculoskeletal pain and prolonged awkward postures are key contributors to worker depression.
• Workplace interventions targeting pain-inducing and improper postures are necessary to support worker mental well-being.
