Abstract: Objective To study the developmental characteristic and influencing factors in children with language developmental delay,and provide scientific reference for these children' early recognition and comprehensive intervention. Methods A total of 240 children,who had developmental delay in language under five years old,were included.Gesell Test was used to evaluate children neurodevelopment. Results 1)After 2 years old,the developmental quotient (DQ) of each domain was significant decline (P<0.001),especially the DQ of language.2) Age and gestational age had statistic differences between children who had only language problem and combined other disorders(P<0.001).But there were no significant differences in gender,delivery,birth weight,maternal educational level and the family history(P＞0.05). Conclusions About 2 years old is a focus age to find language delay in children.Language screening should be strengthened at about 2 years old for the early detection of language delay.Premature delivery is the main factor of developmental delay in language.Avoiding premature delivery is the key to prevent developmental delay in language.
