Symptom på bristande synergonomi och dess samvariation med upplevd produktivitet

Sammanfattning: Aim: The aim of this cross-sectional study was to investigate the prevalence of Computer Vision Syndrome symptoms in office workers conducting ordinary computer work and if the intensity of such symptoms covaried with self-estimated limitations in work productivity.  Method: A digitalized survey consisting of Computer Vision Syndrome Questionnaire and Work Limitations Questionnaire was sent out to 580 office workers at three different organizations. 146 people responded to the survey (25% response rate). After removal due to exclusion criteria’s, 54 (59%) women and 38 (41%) men remained. Multiple regression analysis analyzed the association between visual symptoms and self-assessed productivity loss. Main result: Out of the 92 respondents, 42 were classified as non-Computer Vision Syndrome cases (46%). The estimated prevalence of Computer Vision Syndrome was 54% (50). The multiple regression analysis showed statistically significant associations (p <0,05) between Computer Vision Syndrome symptoms and self-assessed productivity loss. More intense visual symptoms were associated with more self-assessed productivity loss.  Conclusions: More than half of the office workers had Computer Vision Syndrome, which indicates that there is a common occupational health problem for the office workers and that organizations have potential productivity gains. Further research is needed to investigate more confounding factors and to draw conclusions about causality.
