Persistent Neck and Shoulder Pains among Computer Office Workers: A Longitudinal Study

Background & Aims of the Study: In developing countries, with increasing use ofcomputer systems, millions of computer workers are at high risk of neck and shoulderpains. The aim of this study was to assess the relationships between work-related physicaland psychosocial factors and persistent neck and shoulder pains among computer officeworkers.Materials & Methods: This longitudinal study with 1-year follow-up was conductedamong all eligible computer office workers (n=182) of Shahroud universities (northeasternIran) in 2009-2010. Cultural and Psychosocial Influences on Disability (CUPID) questionnaire was used to collect data on demographic characteristics, physical,organizational and psychosocial factors at work, and neck and shoulder symptoms. Chisquare and logistic regression analysis was used to analyze the data through SPSS version16.Results: Computer office workers with the mean±SD age of 32.1±6.7 years and themean±SD weekly work hours of 47.4±8.2 participated in this study. At the baseline 39.6%of workers reported neck and shoulder pains. At one year follow-up, 59.7% of themreported neck pain and 51.3% reported shoulder pain. Significant relationships were foundbetween persistence of neck and shoulder pains and age, gender, and decision latitude atwork.Conclusions: Although neck and shoulder pains were equally prevalent among the studygroup, after one year follow up, persistent neck pain was more than shoulder pain. Age,gender, and decision latitude at work were identified as risk factors for both pains.
