The dose-response relationship between physical activity and school scoliosis screening positive in children and adolescents: a preliminary cross-sectional study

1

Physical inactivity is a recognized risk factor for adolescent idiopathic scoliosis (AIS), with this study exploring detailed physical activity parameters.
2

A total of 1,051 students underwent scoliosis screening, revealing a U-shaped dose-response relationship between physical activity and positive scoliosis screening.
3

Moderate physical activity (approximately 54 min/day, 3–4 days/week) is associated with the lowest odds of positive scoliosis screening.
4

Low and vigorous physical activity levels were linked to higher odds of positive scoliosis screening, highlighting the importance of balanced activity.
5

Participation in aquatic and team sports was inversely associated with positive scoliosis screening, suggesting protective effects against scoliosis.
