【Objective】 To investigate the distribution and its influential factors of the developmental coordination disorder (DCD) of preschool children in Nanjing city. 【Methods】 A cross-sectional survey with cluster random sampling was performed.750 children aged 4~6 years old from 6 kindergartens of Nanjing city were selected as survey venues,whose parents would complete the developmental coordination disorder questionnaire and the basic situation questionnaire and the Chi-square test and unconditional logistic regression analysis were used to analyze the data. 【Results】 1) The prevalence of DCD in preschool children was 24.7%.There were high significant difference in the prevalence of DCD among children of different ages(χ2=19.748,P=0.000),and no statistical significance was found between boys and girls(χ2=1.239,P＞0.05).2) The children with DCD were different from the normal children on the age,whether crawling clumsily or not,the time began to walk,the time began to use the spoon,the time began to use the chopsticks as well as the time and interested items for everyday's exercise (P＜0.05).3) Whether crawling clumsily or not,the time began to walk and the average time for everyday's exercise affected the happening of the DCD according to the unconditional logistic regression analysis. 【Conclusions】 The prevalence of DCD is higher in the preschool children population.Measures should be taken to promote the children's coordination ability by the parents and teachers.
