Work with visual display units and musculoskeletal disorders: A cross-sectional study.

Abstract:

BACKGROUND:Epidemiological studies have shown that employees working with visual display units (VDU) are more likely to complain about musculoskeletal disorders (MSDs). The aim of this study has been to evaluate associations among MSDs and individuals and work-related factors. MATERIAL AND METHODS:A total of 1032 VDU workers were assessed about their personal (i.e., age, working history, smoking history, physical activity) and work-related factors (i.e., predominant job tasks performed, work posture). Work environment was evaluated regarding fulfillment of the standard ISO 9241-5:1998. The investigation required a direct observation of participants (in order to accurately assess the prevalence of MSDs) and workstations. Adjusted odds ratios (ORa) were calculated by means of the logistic regression model. RESULTS:Prevalence of MSDs was relatively high (53%). In general, MSDs were significantly associated with female sex (OR = 2.832, 95% confidence interval (CI): 2.178-3.683), age ≥ 50 years old (OR = 2.231, 95% CI: 1.236-4.026), longer exposure to VDU, both as working history (10-14 years: OR = 1.934, 95% CI: 1.301-2.875; ≥ 15 years: OR = 2.223, 95% CI: 1.510-3.271) and working time (30-39 h/week: OR = 1.537, 95% CI: 1.087-2.273). Inappropriate workstation design was confirmed by the multivariate analysis as a risk factor for MSDs (ORa = 2.375, 95% CI: 1.124-5.018). CONCLUSIONS:Musculoskeletal disorders were significantly associated with individual factors as well as characteristics of work environment. An appropriate design of workstations may significantly reduce their prevalence amongst VDU workers. Med Pr 2016;67(6):707-719. WSTĘP:Badania epidemiologiczne wykazały, że osoby pracujące przy monitorach ekranowych (visual display units – VDU) częściej skarżą się na zaburzenia mięśniowo-szkieletowe (musculoskeletal disorders – MSDs). Celem badania była ocena związku między MSDs a cechami indywidualnymi pracowników i czynnikami związanymi z pracą. MATERIAŁ I METODY:Badanie przeprowadzono wśród 1032 osób używających VDU w pracy. Zebrano dane dotyczące cech indywidualnych badanych (wiek, staż pracy, historia palenia, aktywność fizyczna) i czynników związanych z wykonywaną pracą (najczęstsze czynności, pozycja ciała). Oceniono też zgodność środowiska pracy z normą ISO 9241-5:1998. W celu dokładnej analizy występowania MSDs przeprowadzono bezpośrednią obserwację osób badanych i ich stanowisk pracy. Skorygowane ilorazy szans (adjusted odds ratios – ORa) obliczono z zastosowaniem modelu regresji logistycznej. WYNIKI:Częstość występowania MSDs była stosunkowo wysoka (53%). Zaobserwowano statystycznie istotną zależność między MSDs a płcią żeńską (OR = 2,832, 95% przedział ufności (confidence interval – CI): 2,178–3,683), wiekiem powyżej 50 lat (OR = 2,231, 95% CI: 1,236–4,026) i dłuższym narażeniem na VDU – zarówno w wyniku dłuższego stażu pracy (10–14 lat: OR = 1,934, 95% CI: 1,301–2,875; ≥ 15 lat: OR = 2,223, 95% CI: 1,510–3,271), jak i większego wymiaru czasu pracy (30–39 godz./tydzień: OR = 1,537, 95% CI: 1,087–2,273). Analiza wieloczynnikowa potwierdziła, że nieodpowiednio zorganizowane stanowisko pracy jest czynnikiem ryzyka MSDs (ORa = 2,375, 95% CI: 1,124–5,018). WNIOSKI:Występowanie zaburzeń mięśniowo-szkieletowych jest istotnie związane z indywidualnymi cechami pracownika i właściwościami środowiska pracy. Odpowiednio zorganizowane stanowiska pracy mogą znacznie zmniejszyć częstość występowania MSDs u osób pracujących przy VDU. Med. Pr. 2016;67(6):707–719.
