Prevalence of developmental disorders (DDs) has been increasing worldwide. This study identifies a trend in their prevalence and incidence, using nationwide population-based data to analyze the characteristics of children with DDs in Korea. The prevalence of DDs steadily increased by more than four times (from 0.6 to 2.5) from 2003 to 2017. Boys had higher incidence than girls throughout the period, during which the gap increased from 19.1 to 31.4%. The incidence also increased by the size of city and medical insurance quartile. The ratio of autism spectrum disorder, developmental delay and language disorders among the total incident cases of DDs increased by 13.7%, 817.6%, and 30.7%, respectively, indicating their contribution to the trend of increasing prevalence.
发育障碍(DDs)的患病率在全球范围内不断上升。本研究使用全国性基于人群的数据,分析了韩国患有 DDs 的儿童的特征,以确定其患病率和发病率的趋势。2003 年至 2017 年,DDs 的患病率稳步增加了四倍多(从 0.6 增加到 2.5)。在此期间,男孩的发病率一直高于女孩,差距从 19.1%增加到 31.4%。发病率也随着城市规模和医疗保险四分位数的增加而增加。自闭症谱系障碍、发育迟缓、语言障碍在 DDs 总发病例中的比例分别增加了 13.7%、817.6%和 30.7%,表明它们对患病率上升趋势的贡献。
