Abstract:

〔Abstract〕 Objective： To investigate the language developmental delay of children aged 18-36 months in urban area of Panzhihua City. Methods： Stratified cluster sampling method was used to select children aged 18-36 months for questionnaire survey， language development screening， GESELL developmental diagnosis， physical examination， hearing test and other related examinations and diagnoses. Results： The detection rate of language retardation was 8.38%. Among them， the detection rate of boys was 11.69% while that of girls was 4.02%， and the ratio of detection rate of male to female was 3.8：1， and the difference was statistically significant（P< 0.01）.Only language area developmental delay accounted for 8.54%， overall developmental delay accounted for 83.54%， autism spectrum disorder accounted for 4.87%， cerebral palsy accounted for 0.61%， hearing impairment and cleft palate accounted for 1.22% respectively. There was a statistically significant difference in the detection rate of language developmental delay among children of different months（P<0.01）. The detection rate of children aged 18-24 months was the lowest at 5.20%； the detection rate of children aged 25-30 months was the highest， up to 12.53%. Conclusion： The incidence of language developmental delay in early childhood of boys is higher than that of girls， and it is most obvious in children aged 25 to 30 months. Overall global developmental delay accounts for the vast majority of language developmental delays.
