Objective To explore the developmental characteristics of language developmental retardation children in different age groups, and to provide scientific basis for early detection and comprehensive intervention. Methods A total of 652 children aged 1-3 years who were admitted due to language development retardation were evaluated by S-S language retardation method from Janurary 2018 to March 2019.They were divided into four groups according to different age groups, and the developmental characteristics of children in different groups were analyzed and described. Results 1) With the growth of age, the number of children seeking medical treatment for language problems was increasing, and the peak age was >1.5-2.5 years old.Boys were significantly more than girls(male 526, female 126), and there was no difference between each of the two groups(P=0.102).2) Abnormal communication attitude in 1-1.5 years old group was 11.1%,>1.5-2 years old group was 15.7%,>2-2.5 years old group was 12.2%,>2.5-3 years old group was 21.9%.There was no statistical difference in the proportion of abnormal communication attitude between each group(χ2=6.171,P=0.104).Abnormal motor subject and abnormal language understanding in 1-1.5 years old group were 26.7% and 66.7%,>1.5-2 years old group were 46% and 82.8%,>2-2.5 years old group were 68.1% and 93.9%,>2.5-3 years old group were 78.1% and 99.0%.There was statistically significant differences among the four groups (P<0.001).3) As the age increases, the proportion of abnormal motor task and language comprehension ability increases gradually, and the most significant difference was around 2 years old. Conclusions Language retardation is most common in children around age 2, and is more likely to have comprehension abnormalities and other developmental problems after age 2.Therefore, it is necessary to do early screening and early intervention training for this age group.
