We compared the prevalence of self-injurious behaviors (SIB) in preschoolers aged 30-68 months with autism spectrum disorder (ASD) (n = 691) versus other developmental delays and disorders (DD) (n = 977) accounting for sociodemographic, cognitive, and medical factors. SIB prevalence was higher in ASD versus all DD [adjusted odds-ratio (aOR) 2.13 (95% confidence interval (95% CI) 1.53, 2.97)]. In subgroup analyses, SIB prevalence was higher in ASD versus DD without ASD symptoms [aOR 4.42 (95% CI 2.66, 7.33)], but was similar between ASD and DD with ASD symptoms [aOR 1.09 (95% CI 0.68, 1.77)]. We confirmed higher prevalence of SIB in ASD versus DD, independent of confounders. In children with DD, SIB prevalence increased with more ASD symptoms. These findings are informative to clinicians, researchers, and policymakers.
我们比较了 30-68 个月自闭症谱系障碍(ASD)(n=691)和其他发育迟缓障碍(DD)(n=977)学龄前儿童的自伤行为(SIB)的患病率,同时考虑了社会人口统计学、认知和医疗因素。与所有 DD 相比,ASD 中的 SIB 患病率更高[调整后的优势比(aOR)为 2.13(95%置信区间(95%CI)为 1.53,2.97)]。在亚组分析中,与无 ASD 症状的 DD 相比,ASD 中的 SIB 患病率更高[aOR 为 4.42(95%CI 为 2.66,7.33)],但与有 ASD 症状的 DD 相比,ASD 中的 SIB 患病率相似[aOR 为 1.09(95%CI 为 0.68,1.77)]。我们证实了 ASD 中 SIB 的患病率高于 DD,且不受混杂因素的影响。在 DD 儿童中,SIB 的患病率随着 ASD 症状的增加而增加。这些发现为临床医生、研究人员和政策制定者提供了信息。
