Objective: The etiology of nonspecific neck pain is widely accepted to be multifactorial. Each risk factor has not only direct effects on neck pain but may also exert effects indirectly through other risk factors. This study aimed to test this hypothesized model in office workers. Methods: A one-year prospective cohort study of 559 healthy office workers was conducted. At baseline, a self-administered questionnaire and standardized physical examination were employed to gather biopsychosocial data. Follow-up data were collected every month for the incidence of neck pain. A regression model was built to analyze factors predicting the onset of neck pain. Path analysis was performed to examine direct and indirect associations between identified risk factors and neck pain. Results: The onset of neck pain was predicted by female gender, having a history of neck pain, monitor position not being level with the eyes, and frequently perceived muscular tension, of which perceived muscular tension was the strongest effector on the onset of neck pain. Gender, history of neck pain, and monitor height had indirect effects on neck pain that were mediated through perceived muscular tension. History of neck pain was the most influential effector on perceived muscular tension. Conclusions: The results of this study support the hypothesis that each risk factors may contribute to the development of neck pain both directly and indirectly. The combination of risk factors necessary to cause neck pain is likely occupation specific. Perceived muscular tension is hypothesized to be an early sign of musculoskeletal symptoms.

Objective: All occupations expose workers to varied and unique conditions. The nature of work has been recognized as influencing the health of workers. Whether predictors for chronic neck and low back pain would be occupation-specific is unknown. This study aimed to identify predictors for chronic neck and low back pain in a cohort of office workers. Methods: A prospective study was carried out among 669 healthy office workers. At baseline, risk factors were assessed using a questionnaire and standardized physical examination. A symptomatic case was defined as an individual who reported pain greater than 30 mm on a 100-mm VAS, and chronic pain was defined as experiencing ongoing neck or low back pain for greater than 3 months over the past 6 months. Two regression models were built to analyze the risk factors for developing chronic neck and low back pain. Results: Of the sample, 17 and 27% of office workers who reported a new onset of neck or low back pain developed chronicity, respectively. Predictors for chronic neck pain were high body mass index, frequent neck extension during the work day, high initial pain intensity, and high psychological job demands. The development of chronic low back pain was associated with history of low back pain and high initial pain intensity. Conclusions: The findings suggest that predictors for chronic musculoskeletal pain in a subpopulation may be a subset of predictors identified in a general population or occupation specific. Successful management to prevent chronic musculoskeletal pain may also need to consider the patient's occupation.(J Occup Health 2016; 58: 16–24)
