Computer use and musculoskeletal symptoms among undergraduate university students

• All students used computers, laptop more than desktop.
• The prevalence of computer-related MSS was high.
• MSS prevalence increased significantly year-on-year.
• MSS were significantly associated with daily computer use and hand dominance.
• Computer-related MSS impacted on students lives.

The use of computers has been shown to have the potential for detrimental effects on the musculoskeletal system. Previous research has identified risk factors for computer-related musculoskeletal symptoms (MSS) in the workforce, but the focus of investigation on university students is comparatively recent. There appears to be a relative paucity of research into computer-related MSS in European universities and none to date in Ireland. The primary aim of this study was to determine the prevalence of computer-related MSS in a cohort of undergraduate university students in Ireland. The cross-sectional study design involved a questionnaire of two parts. Part A was a questionnaire adapted from previously used questionnaires and included questions relating to demographic information regarding age, gender, year of study, hand dominance and details of computer use. Part B was a modified (to include only computer-related symptoms) Nordic Musculoskeletal Questionnaire. A total of 312 Health Sciences students were surveyed and 241 responded, giving an overall response rate of 76.9%. All students used a computer, with 95.4% using a laptop. Although the reported duration of computer use was quite low, the prevalence of computer-related MSS was high (52.8%). Increased prevalence of MSS was significantly associated with year of college, average daily laptop use and right hand dominance. A considerable proportion of students reported that MSS impacted on their work (18.3%) and leisure activities (23.6%) and furthermore 17.1% sought medical attention. The current study suggests that further research should be carried out on students from other disciplines and on students in other European universities to facilitate a greater understanding of the risk factors for computer-related MSS in undergraduate students.
