The natural history of idiopathic scoliosis has been studied between 1969 and 1985 in a well-controlled population of school children, 66,200 cases, between 7 and 16 years of age. The incidence of scoliosis needing treatment (25 degrees or more in progress in growing children) was studied with a cross-sectional as well as a longitudinal survey. When using a cross-sectional technique, a decrease of cases being treated was seen after the introduction of a conventional screening program--thus indicating a change in the natural history of moderate scoliosis. This could, however, be explained by the consequence of an accumulation of treated cases, formerly diagnosed and treated later on, seen immediately after the introduction of screening. When the longitudinal method was used, this trend could not be observed. And finally, when taking changes of indication of treatment and of the population into consideration, no tendency at all toward a change in the natural history could be seen.
1969年至1985年间，在一个控制良好的学龄儿童群体（66200例，年龄在7至16岁之间）中对特发性脊柱侧弯的自然病史进行了研究。采用横断面调查和纵向调查相结合的方式，研究了需要治疗的脊柱侧弯（生长发育期儿童侧弯进展达25度或以上）的发病率。采用横断面技术时，在引入传统筛查项目后，接受治疗的病例数有所减少，这表明中度脊柱侧弯的自然病史发生了变化。然而，这可能是由于筛查引入后立即出现的一种情况所导致的，即之前被诊断但后来才接受治疗的病例积累的结果。当采用纵向方法时，未观察到这种趋势。最后，当考虑到治疗指征和人群的变化时，未发现自然病史有任何变化的趋势。
