COMPARATIVE STUDY OF COMPUTER USAGE PATTERNS AND PREVALENCE OF MUSCULOSKELETAL SYMPTOMS AMONG COLLEGE STUDENTS

摘要

Recent studies have shown that computer-use-related musculoskeletal discomfort is prevalent in college students. In this paper two studies of college student computer usage, conducted five years apart (2003 and 2008), are compared. The participants in both studies completed online computer usage surveys. Questions included the duration of computer use, at what times they would most likely be using a computer, and at what locations. Some questions were focused on what safe computing practices the student had possibly adopted, such as taking breaks. Both studies indicated that students often assume awkward postures when computing. Students also reported continuously computing, with no breaks, though breaks are recommended by computer ergonomics programs in other sectors. Reported discomfort associated with computer use indicates that students are already experiencing musculoskeletal symptoms. This study can guide in the development, implementation, and evaluation of changes in the equipment and/or training that will reduce the ergonomic risks to students.
