Abstract：Objective To investigate the distribution of preschool children with developmental coordination dis-order（DCD），and its relationship with family environment in Nanjing city. Methods A cross-sectional survey with stratify cluster random sampling was conducted. 750 children aged 4 to 6 years from 6 kindergartens of Nanjing city were selected and their parents were asked to complete the developmental coordination disorder questionnaire and the family environment questionnaire. Partial correlation were used to analyze the relationship between DCD in preschool children and their family environment. Results （1）The prevalence of DCD in preschool children was 24.7%：26.5% in boys and 22.9% in girls. There was no significant difference in the prevalence of DCD among children of different gender（χ2 = 0.790，P = 0.423）. The prevalence of children with DCD in different age groups among 4，5，6 were 36.0%，24.2%，16.4%，respectively，and no statistical significance was found among children of different ages（χ2 = 20.584，P = 0.000）. （2）The difference of fineness handwriting and coordination ability among children with DCD was significant in different gender（t = 3.419、2.045，P ＜ 0.05）. There were significant differences between equilibrium control and fineness handwriting in children among DCD of different age group（t = 6.626、8.704，P ＜ 0.01）. （3）There were significant differences upon independence and morality concept between DCD group and normal group（t = 0.888、2.122，P ＜ 0.05）. There were significantly associations between children with DCD and the independence and morality concept of family environment scales. Conclusion The prevalence of DCD is higher in the preschool children population. The nonage diagnosis and nonage intervention of children with DCD is very important，and family environmental factors should be emphasized for children with DCD in nonage intervention.
