Computer-usage and associated musculoskeletal discomfort in college students

Abstract

Background: High use of computers among college students and the resulting musculoskeletal disorders raises concerns regarding healthy usage patterns.

Objective: The purpose of this study is to examine college student's computer usage and related musculoskeletal discomfort.

Methods: A sample of 338 college students completed a cross-sectional survey consisting of demographic questions, musculoskeletal discomfort indicators and questions regarding computer use.

Results: The sample included 232 (68.6%) females and 106 (31.3%) males. 61% students had reported discomfort during or after working using computers with greatest discomfort in the neck (68.5%) and lower back (66%). Female students were more likely than male students to report any musculoskeletal discomfort (66% vs 51%), p < .05. Sitting duration, awkward postures and length of time (more than eight hours) were significantly associated with musculoskeletal discomfort (R2 = 0.24, p < .01).

Conclusion: Most female college students reported musculoskeletal discomfort during or after computer use. Daily use of computer for more than eight hours, assuming awkward postures and sitting for long duration without breaks were found to be significantly related to musculoskeletal discomfort. Emphasizing good computing habits in college students to avoid musculoskeletal symptoms in the future will prevent morbidity in future workforce.
