Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of study: 1. To investigate the prevalence of scoliosis, other spinal deformities, myopia, and visual impairments in adolescents (aged 6-18) in Zhejiang Province.

2.To track 8-year dynamic changes in spinal curvature and analyze associations between scoliosis, vision disorders, and potential risk factors.

3.To deliver scoliosis health education during screenings.

4.To mitigate scoliosis progression through early detection and intervention.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Scoliosis is the most common pediatric musculoskeletal disorder, affecting up to 4% of otherwise healthy children worldwide. Approximately 80-90% of cases are idiopathic scoliosis (IS), predominantly emerging during adolescence. While mild IS often causes no symptoms, moderate cases may lead to spinal deformity and mild respiratory dysfunction, with severe cases potentially resulting in cardiopulmonary compromise or even paralysis.

Despite extensive research exploring potential causes - including genetic, neuroendocrine, skeletal, muscular, postural, biomechanical and lifestyle factors - the underlying mechanisms of IS remain unclear. Bracing currently stands as the only proven conservative treatment to slow progression, yet 20-30% of braced patients still require eventual surgical correction. Adolescence represents both a critical window for rapid curve progression and the optimal period for effective intervention. Early screening has been demonstrated to significantly improve outcomes, highlighting the importance of preventive strategies during this developmental stage.

Recent studies across various populations have reported scoliosis prevalence rates ranging from 0.27% to 3.5%, with notable regional variations:

Singaporean studies found rates between 0.27%-2.49%

Greek research reported 1.7% prevalence

Large-scale US screening showed 0.9% prevalence

Chinese studies documented rates from 1.07% (Guangzhou) to 3.5% (Hong Kong)

Most existing research has been cross-sectional in design, lacking prospective data on curve progression patterns and associated risk factors.

This prospective cohort study aims to:1. To investigate the prevalence of scoliosis, other spinal deformities, myopia, and visual impairments in adolescents (aged 6-18) in Zhejiang Province.

2.To track 8-year dynamic changes in spinal curvature and analyze associations between scoliosis, vision disorders, and potential risk factors.

3.To deliver scoliosis health education during screenings.

4.To mitigate scoliosis progression through early detection and intervention.
