The aim of this study was to investigate the relation between laterality and spine deformities in early adolescence, with special reference to sex differences. Interviews, anthropometric measurements and clinical examinations of body posture were carried out on a sample of 2546 schoolchildren, aged from 11 to 14 years, in seven elementary schools in the centre of Belgrade. Possible confounding factors (age, sex, body weight and body height) were controlled for. The overall prevalence of spine deformities (scoliosis and/or thoracic hyperkyphosis) in the investigated population was 11.8%, out of which there were 7.8% adolescents with scoliosis, 4.0% with thoracic hyperkyphosis, and 0.3% with both spine deformities. The prevalence of scoliosis was 2.7 times higher in girls compared to boys (11.7% vs. 4.3%) while the prevalence of thoracic hyperkyphosis was 1,6 higher among boys (5.0% vs. 3.2%). We found 7.6% of the schoolchildren examined to be left-handed. Left handedness was significantly related to scoliosis in girls (crude OR = 1.60 and 95% confidence interval = 1.01-2.54). Multivariate analysis showed that significant independent factors for scoliosis were female sex (p < 0.001), age (p = 0.01) and left handedness (p = 0.02). We did not find any appreciable relation between left handedness and thoracic hyperkyphosis in both sexes.
本研究旨在调查青春期早期偏侧性与脊柱畸形之间的关系，特别关注性别差异。对贝尔格莱德市中心7所小学的2546名11至14岁学童样本进行了访谈、人体测量和身体姿势临床检查。对可能的混杂因素（年龄、性别、体重和身高）进行了控制。被调查人群中脊柱畸形（脊柱侧弯和/或胸椎后凸）的总体患病率为11.8%，其中脊柱侧弯青少年患病率为7.8%，胸椎后凸患病率为4.0%，两种脊柱畸形均有的患病率为0.3%。女孩脊柱侧弯患病率比男孩高2.7倍（11.7%对4.3%），而男孩胸椎后凸患病率比女孩高1.6倍（5.0%对3.2%）。我们发现接受检查的学童中有7.6%是左撇子。左撇子与女孩脊柱侧弯显著相关（粗优势比=1.60，95%置信区间=1.01-2.54）。多变量分析表明，脊柱侧弯的显著独立因素是女性性别（p<0.001）、年龄（p=0.01）和左撇子（p=0.02）。我们未发现左撇子与男女胸椎后凸之间存在任何明显关系。
