Latent class-derived patterns of musculoskeletal disorders in sedentary workers and chair ergonomic design.

This study aimed to define specific patterns of multisite musculoskeletal disorders (MSDs) in office employees and to examine how derived patterns relate to ergonomic chair design. This cross-sectional study of 254 office employees extracted major patterns of MSDs using latent class analysis and investigated the association with ergonomic chair design. Four major patterns of MSDs were extracted using latent class analysis: class 1 (12.

Association of derived patterns of musculoskeletal disorders with psychological problems: a latent class analysis.

Background: Musculoskeletal symptoms often occur in more than one anatomical site. The present study aimed to define specific patterns of multisite musculoskeletal disorders and examine how these patterns are related to common psychological problems.

Methods: Using the data from an interview-based health survey of 358 samples of the industrial manufacturing male employees, we derived major patterns of musculoskeletal complaints using latent class analysis and investigated its association with psychological problems score extracted from depression, anxiety, and stress measured by Depression/Anxiety/Stress Scale (DASS-21).
