Factors Associated with Musculoskeletal Disorders (MSDs) Complaints Among Workers at PT Lucky Light Globalindo in 2026

Abstract

Musculoskeletal Disorders (MSDs) affect the body's movement system, including muscles, bones, joints, and connective tissues, and are a leading cause of physical disability worldwide. This study aimed to identify factors associated with MSDs complaints among workers at PT Lucky Light Globalindo. This quantitative cross-sectional study involved 74 workers selected by total sampling. MSDs complaints were measured with the Nordic Body Map (NBM) questionnaire, working posture was observed with the Rapid Entire Body Assessment (REBA) sheet, and other variables via a characteristics questionnaire. Data were analyzed univariately and bivariately using the Chi-Square test. A total of 20.3% of workers had moderate-to-high-risk MSDs complaints and 79.7% low-risk, mostly in the waist, back, and neck. No association was found between age (p = 0.771), sex (p = 0.265), smoking habit (p = 0.575), exercise habit (p = 0.367), nutritional status (p = 0.523), length of service (p = 0.124), working posture (p = 0.543), or working duration (p = 0.190) and MSDs complaints. Despite no statistical association, MSDs complaints still occurred in some workers. The company should install 20-20-20 rule stickers on computer users' desks, provide self-stretching educational media, conduct safety talks and display posters on ergonomic posture, and optimize rotational sports schedules.
