Abstract
A group of 5953 adolescents, ages 11-17 years (2939 boysand 3014 girls) were examined in a school screening pro-gram using two standard positions: standing forwardbending (FB) and seated forward bending. TA was evalu-ated in both positions using a Pruijs scoliometer whichmeasured the angle of trunk inclinations (ATIs) across theback at each of three regions: thoracic, thoracolumbar andlumbar. An abnormal ATI was defined as being beyond 2standard deviations from the mean for region, age, genderand position, and this was termed severe TA. Each childwas assigned to a relatively lower or relatively higher BMIgroup using a median value of BMI by age and sex. The sit-ting FB position is thought to express intrinsic TA freefrom extrinsically-induced effects of any leg-length ine-quality.
Highlights
Recent findings have linked BMI in girls with thoracic adolescent idiopathic scoliosis (AIS) to skeletal asymmetries of the spine and upper arm
In the sitting forward bending (FB) position relatively lower BMIs, after correcting for age, are associated with a greater number of severe TAs than with relatively higher BMIs in both boys and girls. It appears that body fat, BMI, menarche and TA have mechanisms in common during development
BMI is a surrogate measure for body fat and circulating leptin levels
