Age- and sex-specific prevalence of scoliosis and the value of school screening programs.
A prevalence study of idiopathic scoliosis was conducted among 29,195 children of a community health district in the province of Quebec. The study was designed to determine whether a permanent screening program for idiopathic scoliosis was justified. The prevalence of the condition among school children aged 8 to 15 years was 42.0 per 1,000 in the screened population, 51.9 per 1,000 among girls, and 32.0 per 1,000 among boys. The positive predictive value of the bending test is estimated as 42.8 per cent for scolioses of 5 degrees or more; it is only 6.4 per cent when curves of 15 degrees or more are considered. The average cost of finding one child with a scoliosis of 5 degrees or more is $194. Mass screening for idiopathic scoliosis does not seem to be justified in the present state of knowledge of the disease.
