Methods A total of 1 016 children aged 18~36 months from the Department of Child Health Care in Sichuan Provinicial Hospital of Women and Children were enrolled as subjects in the study,and the Language Development Screening Scale for infants and young children was used as the investigation tool. Results Boys aged 18～30 months had significantly lower scores than girls in the same age group (P<0.05),and the incidence of language development retardation of boys was significantly higher than that of girls (P<0.05).The rapid growth of language in boys and girls appeared in their 24 months,but the language development had no significant gender difference between from 30 months to 36 months (P>0.05).
