Abstract Objective To summarize the characteristics of early language development delay in children of different ages and genders, and provide evidence for the early intervention. Methods A total of 659 children（490boys and 169 girls）aged 12-35 months diagnosed with language development delay in the Department of Child Health Care, Chongqing Maternal and Child Health Hospital from November 2020 to December 2021 were selected as the research subjects. The children’s language development level was evaluated by using Gesell developmental schedule. The children were grouped on age and gender, and age and gender differences in language development levels were examined. Results There was no significant gender difference in the language development level of children in the 12-23 months group. In the 24-35 months group, boys had significantly lower scores in speech and language expression than girls
（P<0.05）. The proportion of abnormal speech and language expression in children aged 24-35 months, and the proportion of abnormal auditory perception and understanding in boys, were significantly higher than those in the 12-23 months group （P< 0 .05）. Conclusion Among children with language development delay, boys have poorer language expression abilities. Especially after 24 months of age, the language development of boys is more delayed than that of girls, and the proportion of abnormal auditory perception and understanding is higher than that of boys in younger age groups. Therefore, in clinical practice, attention should be paid to the language development of young children, especially boys, and intervention should be implemented as early as possible.
