Scoliosis is a three-dimensional deformity of the spine with lateral curvature in addition to the rotation of vertebral bodies. The aim of the present study was to determine the prevalence of adolescent idiopathic scoliosis (AIS) in our society and its demographic-related factors.
This was a cross-sectional study that took place from November 2014 to March 2015 in Isfahan, Iran. During the period of study, 24 schools were randomly chosen from six zones by a simple random sampling method. In each school, about 120 students were randomly selected and evaluated. Anterior forward bending test and scoliometry were done in all students and suspicious ones referred to Alzahra spine clinic for further evaluation. The diagnosis of AIS was based on radiographic finding and Cobb angle more than 10°. Data about age, sex, height, body mass index, hand dominancy, and type of schoolbag were recorded.
A total number of 3018 children were evaluated and 19 were diagnosed with AIS that showed the prevalence of 0.62%. None of the study variables had a significant relation with the presence of AIS. The cutoff point for the detection of AIS with scoliometry was calculated as 3.5, with a sensitivity of 73.7% and specificity of 86.7%.
The prevalence of AIS in our area was 0.62%, which was lower than previous reports and did not have a relation with demographic factors; however, screening surveys identify a significant number of children with AIS who could benefit from preventive treatment.
脊柱侧弯是脊柱的三维畸形，除椎体旋转外还伴有侧方弯曲。本研究的目的是确定我们社会中青少年特发性脊柱侧弯（AIS）的患病率及其与人口统计学相关的因素。
这是一项横断面研究，于2014年11月至2015年3月在伊朗伊斯法罕进行。在研究期间，通过简单随机抽样方法从六个区域中随机选择了24所学校。在每所学校中，随机选择约120名学生进行评估。对所有学生进行前屈试验和脊柱侧弯测量，可疑者转诊至阿尔扎赫拉脊柱诊所进行进一步评估。AIS的诊断基于影像学检查结果和Cobb角大于10°。记录有关年龄、性别、身高、体重指数、利手和书包类型的数据。
共评估了3018名儿童，其中19名被诊断为AIS，患病率为0.62%。没有一个研究变量与AIS的存在有显著关系。脊柱侧弯测量检测AIS的截断点计算为3.5，灵敏度为73.7%，特异度为86.7%。
我们地区AIS的患病率为0.62%，低于先前的报告，且与人口统计学因素无关；然而，筛查调查发现大量AIS儿童可从预防性治疗中受益。
