Objective To retrospectively analyze the characteristics of neurodevelopment in children with language developmental delay aged 18 to 36 months, so as to provide theoretical evidence for further assessment and intervention.
Methods Children with language problems aged 18 to 36 months from 2018 to 2019 were enrolled in this study from Children′s Hospital of Soochow University. Children′s neurodevelopment was assessed by Chinese Children Development Scale and Early Language Milestone Scale, which divided them into two groups according to the results: simple language delay and global developmental delay. The development quotients(DQ) of each dimension and early language development were compared within two groups. Positive detection rate of autism was analyzed.
Results A total of 700 children were included. There were no significant differences in age(
P=0.09) and gender(
P=0.15)between the two groups. The development of language areas, gross motor, fine motor, adaptability and social interaction in global developmental delay group was significantly worse than that in simple language delay group(
t=15.08, 20.26, 25.68, 18.76, 39.79,
P＜0.001). In addition, early language development in general language development, language understanding, expression and auditory perception, and visual-related language decreased significantly in global developmental delay group compared with simple language delay group (
t=8.20, 10.23, 9.18. 11.39,
P<0.001). Language delay was related to the DQ of fine motor, adaptability and social interaction in simple developmental delay group (
r=0.127, 0.146, 0.238,
P<0.001), while it was associated with the DQ of each dimension in global developmental delay group(
r=0.154, 0.392, 0.390, 0.435,
P<0.001). The positive detection rate of autism screening in global developmental delay group was significantly higher (
Conclusion Children with early language delay combined with backwardness in multiple dimensions have a significant lag in language development and should be further examined to identify neurodevelopmental disorders.
