Abstract: Objective To analyze the correlation between the national physique evaluation and the indicators of children's coordination disorder in 3- to 6-year-old children in Beijing, so as to provide theoretical basis for further screening of developmental coordination disorders(DCD) in nurseries and kindergartens. Methods From March to April 2019, 253 children aged 3 to 6 years in three kindergartens in Beijing were selected into this study.The Children's Motor Coordination Ability Assessment Scale (Second Edition) (MABC-2) was used to evaluate the prevalence of children's DCD.Children's physical fitness was evaluated by using the early childhood section of the National Physical Fitness Measurement Standards Manual as the standard.Multiple linear regression method was used to analyze the relationship between children's physical fitness and DCD. Results Some indexes in the evaluation of 3- to 6-year-old children's physical fitness had certain correlation with the prevalence of DCD (P<0.05).The total score on physical fitness of DCD children was lower than that of non DCD children.For 3-to 6-year-old children, the risk of DCD decreased when the items of jumping on both feet and the tennis throw scored higher(OR=0.501, 0.507, P＜0.05). Conclusions There is a correlation between physical fitness scores and DCD in children aged 3—6 years.Physical fitness tests may play a supplementary role in screening children with DCD, and further studies with larger samples are warranted.
