Prevalence of eye and visual symptoms among office workers and their relationship to self-assessed productivity loss

Wärme, Josefin January 2020 (has links)
Aim: The dual aims of this descriptive cross-sectional study were: 1) to assess the prevalence of eye-and visual symptoms among a population of office workers and; 2) to analyse if these symptoms were associated with self-assessed productivity. Method: A questionnaire consisting of the Computer Vision Syndrome Questionnaire, Convergence Insufficiency Symptom Scale and the Work Limitations Questionnaire was provided to each employee. Descriptive statistics on the number of individuals classified as eye-and visual symptom cases was computed. Multiple logistic regressions analyses were performed on the individual eye-and visual symptom scores as independent variables with the self-assessed productivity limitation scores as the dependent variable. Main result: Out of 127 office workers, 76 answered the questionnaire (60% response rate). The estimated prevalence’s of eye- and visual symptoms were 73% (95% CI: 61−83%) for Computer Vision Syndrome and 32% (95% CI: 21−43%) for Convergence Insufficiency-related symptoms. The multiple regression analyses revealed strong positive associations between eye/visual symptoms and productivity limitations for both Computer Vision Syndrome scores (p<0.001, r2=0,22) and Convergence Insufficiency-related symptoms scores (p<0.001, r2=0,39). Conclusions: Symptoms of Computer Vision Syndrome and Convergence Insufficiency were both prevalent, the former more so than the later. These symptoms were both strongly associated with limitations in self-assessed productivity. More research efforts are warranted to replicate and explore these work and health associations. / Syfte: Det första syftet i studien var att uppskatta prevalensen av Computer Vision Syndrome och symtom relaterade till konvergensinsufficiens i en population av kontorsarbetare. Det andra syftet var att analysera om det fanns ett samband mellan dessa symtom och självskattad produktivitetsförlust eller inte. Metod: En kvantitativ enkätstudie med tvärsnittsdesign genomfördes med följande enkätinstrument: Computer Vision Syndrome Questionnaire, Convergence Insufficiency Symptom Scale and Work Limitations Questionnaire. Deskriptiv statistik beräknades för prevalenserna av antalet fall som var drabbade av respektive arbetshälsoproblem. Två separata multipla regressionsanalyser genomfördes dessutom. Huvudresultat: 76 kontorsarbetare svarade på enkäten (60 % svarsfrekvens). Den uppskattade prevalensen av Computer Vision Syndrome var 73% (95% CI: 61−83%) och av symtom relaterade till konvergensinsufficiens var 32% (95% CI: 21−43%). De multipla regressionsanalyserna visade statistiskt signifikanta (p < 0,001) samband mellan både Computer Vision Syndrome och symtom relaterade till konvergensinsufficiens, med självskattad produktivitetsförlust. Ju mer synsymtom en person skattade, desto högre var den självskattade produktivitetsförlusten. Slutsats: Nästan tre fjärdedelar av kontorsarbetarna hade Computer Vision Syndrome och en tredjedel uppgav symtom relaterade till konvergensinsufficiens. Detta är ett arbetshälsoproblem för de drabbade kontorsarbetarna som behöver åtgärdas, både för de möjliga arbetshälsovinsterna för arbetstagarna och för de möjliga produktivitetsvinsterna för företagen. Större studier behövs för att bekräfta och vidare analysera sambanden mellan synhälsa och arbetsproduktivitet.
