INTRODUCTION: This study aimed to evaluate the six-month incidence and possible risk factors of neck discomfort among sedentary workers. METHODS: Data, including demographic characteristics, work history, psychological characteristics and prevalent neck discomfort of 157 sedentary workers was collected by a questionnaire. A follow-up questionnaire was administered six months later to calculate the incidence of symptoms and related disability. RESULTS: The six-month incidence of neck discomfort was 23.5% (12/51). The two groups of prevalent and non-prevalent subjects showed no difference in demographic data and work characteristics except for work load (p<0.05) and score in "job control" in the Job Content Questionnaire (JCQ) (p<0.05). In logistic regression, light-load work (versus no-load work, OR = 0.10, p = 0.023) and higher score of 'job control' in JCQ (OR = 0.86, p = 0.031) were significant protecting factors. CONCLUSION: The six-month incidence rates of neck discomfort in our subjects were high. Light-load work and a higher score of 'job control' were important preventive factors. The results provide an epidemiological basis for prevention of neck discomfort in different working populations.
