%X Community nurses and physical therapists in the Southern Health region of Norway including about 12000 school children aged 12 years were invited to participate. All participating community nurses and physical therapists fulfilled an educational course to improve their knowledge about AIS and learn the screening procedure including the Adam Forward Bending Test and measurement of gibbus using a scoliometer.Sub-regions including 4000 school children participated. The prevalence of idiopathic scoliosis defined as a positive Adam Forward Bending Test, gibbus > 7กใ and primary major curve on radiographs > 10กใ, was 0.55%. Five children (0.13%) had a major curve > 20กใ. Bracing was not indicated in any child; all children were post menarche; four had Risser sign of 4, and one with Risser 1 did not have curve progression > 5กใ at later follow-up. In one of these 5 children however, the major curve progressed to 45กใ within 7 months after screening and the girl was operated.The point prevalence of AIS in 12- year old children is in agreement or slightly lower than previous studies. The screening model employed demonstrates acceptable sensitivity and specificity and low referral rates. Screening at the age of 12 years only was not effective for detecting patients with indication for brace treatment.There is a wide variation in the reported prevalence of adolescent idiopathic scoliosis (AIS). One study suggests that about 2.0% of adolescent children are found with screening to have scoliosis with a Cobb angle of > 10กใ, about 0.5% > 20กใ, and only 0.1% > 40กใ[1]. A review of twenty peer-reviewed papers shows a wide range variation of AIS prevalence in different countries with higher prevalence rates in the northern geographic latitudes and lower prevalence rates as the latitude is approaching the equator.(Finland 12%, Singapore 0.9%.) [2]. The prevalence of scoliosis > 20กใ in Scandinavia is reported to be 1.1% for girls and 0.1% for boys in another study [3]. Point prevalence is a m
