This study analyzed the incidence of treatment of scoliosis using a cross-sectional and a lon-gitudinal technique.
To follow the incidence of treated scoliosis in Malmö, Sweden, in children both between 1970 and 1977 and compare observations with those of a study from 1988, in which the incidence of this disorder was followed in children born between 1963 to 1969. of Background Data.
During the late 1970s and early 1980s, the incidence of treated scoliosis decreased yearly in Malmö.
This trend was supported by other reports.
However, introduction of worldwide screening for scoliosis was a confounding factor.
When cohorts of cnildren born between 1963 and 1969 were analyzed, no change was found.
In a study in Malmö in 1988, this was shown to be an effect of using a longitudinal instead of a cross-sectional technique of analyzing the data.
In a cross-sectional study, the authors registered all new treatments for idiopathic scoliosis, brace treatments, or direct surgery, for each year between 1984 and 1993.
In a longitudinal study, all new treatments in each cohort of children born between 1970 and 1977 were followed.
The results were compared with figures from the 1988 study.
After the introduction of school screening in 1976, a peak in the incidence of treated scoliosis was seen in 1977.
After a continuous decrease in the incidence until 1983, a steady state developed. (...)
