Outcome Measures

Primary Outcomes (2)

  • Change in Major Cobb Angle

    Major curve magnitude will be measured on standing full-spine radiographs using the standard Cobb method.

    Baseline and every 6 months up to 24 months

  • Change in Angle of Trunk Rotation (ATR)

    Trunk asymmetry will be assessed using a scoliometer to measure angle of trunk rotation.

    Baseline and every 6 months up to 24 months

Secondary Outcomes (4)

  • Scoliosis Research Society-22 (SRS-22) Questionnaire Score

    Baseline and every 6 months up to 24 months

  • Gut Microbiota Composition

    Baseline and Month 6

  • Gastrointestinal Symptoms

    Baseline and Month 6

  • Serum Bile Acid Levels

    Baseline and Month 6

Study Arms (2)

Bifidobacterium breve Supplementation plus Lifestyle Education

EXPERIMENTAL

Participants in this arm will receive oral Bifidobacterium breve supplementation at a dose of 4.5 × 10\^6 CFU daily for 6 months, together with a one-time standardized lifestyle education session at baseline. The education program will include guidance on healthy diet, appropriate physical activity, and avoidance of unnecessary antibiotic use. Adherence to probiotic supplementation will be reinforced by regular telephone follow-up.

ACTIVE COMPARATOR

Participants in this arm will receive the same standardized lifestyle education session and study materials as the experimental group, but no probiotic supplementation will be provided.
