Abstract
Objective: This study investigated the presence of musculoskeletal symptoms in high school
adolescents from public schools and its association with electronic device use.
Methods: The sample consisted of 961 boys and girls aged 14---19 years who answered a questionnaire
regarding the use of computers and electronic games, and questions about pain
symptoms and physical activity. Furthermore, anthropometric assessments of all volunteers
were performed. The chi-squared test and a multiple logistic regression model were used for
the inferential analysis.
Results: The presence of musculoskeletal pain symptoms was reported by 65.1% of the adolescents,
being more prevalent in the thoracolumbar spine (46.9%), followed by pain in the
upper limbs, representing 20% of complaints. The mean time of use for computers and electronic
games was 1.720 and 583 minutes per week, respectively. The excessive use of electronic
devices was demonstrated to be a risk factor for cervical and lumbar pain. Female gender
was associated with the presence of pain in different body parts. Presence of a paid job was
associated with cervical pain.
Conclusion: A high prevalence of musculoskeletal pain in adolescents, as well as an increased
amount of time using digital devices was observed. However, it was only possible to observe an
association between the increased use of these devices and the presence of cervical and low
back pain.
