Neck pain prevalence and associated occupational factors in Portuguese office workers

Objective: This study aimed to assess the prevalence of neck pain and to identify associated occupational factors in Portuguese office workers. Background: There is still necessary to quantify the association of the use of new technologies with neck pain in office workers. Methods: Six hundred-and-one office workers completed online questionnaires with questions related to anthropometric parameters, work-related variables, workstation setup, and musculoskeletal pain from the Portuguese version of the Standardized Nordic Musculoskeletal Questionnaire. Results: The prevalence of neck pain was 56.1%. An average of 35.6% of the office workers with neck pain reported pain in more than three body segments. The significantly risk factors were “age between 50 and 65” [OR: 1.92 (1.26–2.91) P = 0.002], “working without break for 2 h” [OR: 1.82 (1.00–3.31) P = 0.05], “more than 3 h” [OR: 2.41 (1.35–4.10) P = 0.003], screen localization not centered” [OR: 2.01 (1.01–4.00) P = 0.045], and “use of computer mouse more than 50% of the worktime” [OR: 2.05 (1.14–3.71) P = 0.017]. Conclusion: There was a high prevalence of neck pain and a considerable number of painful body segments in office workers. Age, working without break, screen localization and the use of computer mouse where the significant risk factors associated with the development of neck pain. Relevance to industry: A high prevalence of neck pain and number of areas with pain in office workers require a detailed pain mechanism assessment. There were associated occupational risk factors for the development of neck pain. Call for concerted actions to explore optimal and efficient management plans.
