Abstract:
This was a retrospective study that aimed to provide a first estimate of the prevalence of developmental language disorder (DLD) in Mexico, where there is currently a lack of epidemiological data on this disorder. Children aged 4;0 to 6;11 years in the cities of Mexico, Queretaro, and Monterrey were classified into two groups: those with DLD (N = 46) and those with typical language development (N = 497). The diagnosis of DLD was based on standardized norm-referenced assessment and language sample analyses. Children with other disabilities were excluded from the final sample. The final sample consisted of 543 children (55% male; 45% female) aged 4;0 to 6;11 years. The estimated prevalence of DLD was 8.5%. The study has clinical implications given that the prevalence of DLD in Mexico may raise awareness of this long-lasting disorder and may help health and educational authorities establish a system to early identify and diagnose children with DLD.
摘要:
这是一项回顾性研究,旨在对墨西哥发育性语言障碍(DLD)的患病率进行首次评估。目前缺乏这种疾病的流行病学数据。4岁的儿童;0至6岁;墨西哥城市中的11岁,克雷塔罗,和蒙特雷被分为两类:具有DLD的(N=46)和具有典型语言发展的(N=497)。DLD的诊断基于标准化的规范参考评估和语言样本分析。其他残疾儿童被排除在最终样本之外。最终样本包括543名4岁、0至6岁、11岁的儿童(55%男性;45%女性)。DLD的估计患病率为8.5%。该研究具有临床意义,因为墨西哥DLD的患病率可能会提高人们对这种长期疾病的认识,并可能帮助卫生和教育当局建立一个系统来早期识别和诊断DLD儿童。
