The students exercising at least twice a week showed better mental health than those who donot exercise(t = -3.10, p < 0.01). Those who having musculoskeletal symptoms showed higher index of internet addiction score thanthose who do not(t = 4.21, p < 0.01). Those who have no musculoskeletal symptoms tended to have better mental health than thosewho have musculoskeletal symptoms(t = 2.28, p < 0.05). The variables correlated to mental health were internet addiction, subjectivephysical condition, and exercise at least twice a week.
