Key result
Adolescents reporting both excessive screen time (≥2 hours/day) and inactive physical activity status had 8.84 times higher odds of developing adolescent idiopathic scoliosis compared to those meeting guidelines.
Why the study?
Data on the relationship between moderate-to-vigorous physical activity and adolescent idiopathic scoliosis were inconsistent, and the association with screen time remained unclear.
Case-Control (n=1,488)
Odds Ratio: 8.84 (95% CI 3.99–19.61)
p-value: p=<0.05
May inform adolescent scoliosis risk counseling; hypothesis-generating and requires prospective confirmation before practice change.
Background: Adolescent idiopathic scoliosis (AIS) is the most common type of idiopathic scoliosis, affecting approximately 0.61%–6.15% adolescents worldwide. To date, the results on the relationship between moderate-to-vigorous physical activity (MVPA) and AIS were inconsistent, and the association between screen time (ST) and AIS remained unclear. This study aimed to describe MVPA and ST among adolescents, and to explore the independent and joint associations between PA, ST, and AIS.

Zhu et al. (2023) conducted a case-control in Adolescent idiopathic scoliosis (n=1,488). Insufficient physical activity and excessive screen time vs. Meeting physical activity (≥60 min/day) and screen time (<2 h/day) guidelines was evaluated on Adolescent idiopathic scoliosis (OR 8.84, 95% CI 3.99-19.61, p=<0.05). Adolescents reporting both excessive screen time (≥2 hours/day) and inactive physical activity status had 8.84 times higher odds of developing adolescent idiopathic scoliosis compared to those meeting guidelines.
