Gender differences in musculoskeletal discomfort due to computer use among university students in the United States

Abstract

Objective: Women report higher incidence of musculoskeletal discomfort due to computer use. This study examines the gender differences in the association of musculoskeletal discomfort and computing characteristics among university students. Methods: A cross-sectional survey design was used with a sample size of 338 students from a public university. Multivariable logistic regression models were used to assess associations of musculoskeletal discomfort and participant characteristics. Results: 61% of students reported having MSD. Male students between the age group of 26-35 years (AOR=5.086 [CI=1.05-24.48]) and those who only sometimes took breaks (AOR=3.835 [CI=1.25-11.71]) were more likely to report MSDs. Female students who used computer for more than 8 hours a day (AOR=6.199 [CI=2.38-16.11]), those who spent between 5-8 hours (AOR=2.174 [CI=1.04-4.51]), and those who assumed awkward postures (AOR =5.588 [CI= 1.24-25.1]) were more likely to report MSDs after adjustment. Conclusion: It is important to emphasize the benefits of ergonomics for males in the adult age group. Regardless of age, for female students' adequate breaks from using the computer, and avoiding awkward postures are necessary to prevent and mitigate the risk factors of musculoskeletal discomfort. The different risks factors for male and female students have important implications for prevention of musculoskeletal disorders.
