BACKGROUND
Since 1981, we have performed school scoliosis screening (SSS) using Moiré topography in Miyazaki, Japan and attained a certain result in detecting scoliosis. However, this screening system was discontinued due to cessation of repair and production of Moiré topographic equipment. The purpose of this study was to make clear both the results and the problems of SSS by Moiré topography on the basis of our past 33 years' experiences.
METHODS
The subjects were 689,293 students (5th grade boys in 200,329, 5th grade girls in 191,919, 8th grade boys in 151,351, and 8th grade girls in 145,694) who were screened by Moiré topography between 1981 and 2013. The number of students received SSS, the positive rate of Moiré topography, the discovery rate of scoliosis greater than 20°, the reference rate to the second screening, and the positive predictive value of Moiré topography to detect scoliosis greater than 20° were investigated.
RESULTS
The number of students received SSS achieved a peak in 1992. The positive rate of Moiré topography and the discovery rate of scoliosis were highest in 8th grade girls. The reference rates to the second screening were 49.8% in 5th grade students and 41.4% in 8th grade students. The positive predictive values were 2.1% in 5th grade students and 7.6% in 8th grade students.
CONCLUSION
SSS by Moiré topography seemed to be effective in detecting scoliosis although both the positive predictive value and the reference rate to the second screening were low.
背景
自1981年以来，我们在日本宫崎使用莫尔条纹地形术进行学校脊柱侧弯筛查（SSS），在检测脊柱侧弯方面取得了一定成果。然而，由于莫尔条纹地形设备的维修和生产停止，该筛查系统已停用。本研究旨在基于我们过去33年的经验，明确莫尔条纹地形术进行SSS的结果和问题。
方法
研究对象为1981年至2013年间接受莫尔条纹地形术筛查的689293名学生（五年级男生200329名、五年级女生191919名、八年级男生151351名、八年级女生145694名）。调查了接受SSS的学生人数、莫尔条纹地形术的阳性率、大于20°脊柱侧弯的发现率、二次筛查的转诊率以及莫尔条纹地形术检测大于20°脊柱侧弯的阳性预测值。
结果
接受SSS的学生人数在1992年达到峰值。莫尔条纹地形术的阳性率和脊柱侧弯的发现率在八年级女生中最高。五年级学生的二次筛查转诊率为49.8%，八年级学生为41.4%。五年级学生的阳性预测值为2.1%，八年级学生为7.6%。
结论
尽管阳性预测值和二次筛查转诊率都较低，但莫尔条纹地形术进行SSS在检测脊柱侧弯方面似乎是有效的。
