ABSTRACT
Objective@#The purpose of this study is to understand associations of developmental coordination disorders (DCD) and sensory integration disorders (SID) with family environment for motor development.@*Methods@#A questionnaire survey was conducted among 309 parents of 3-4 years old children in two kindergartens in Beijing selected by clustering sampling, using Development Coordination Disorder Questionnaire, Sensory Integrative Function Scale and Family Environment Scale on Motor Development for Urban Preschool Children.@*Results@#Among the 309 children, the prevalence of DCD was 8.1% with gender difference with boys(11.0%) significantly higher than girls(4.4%)(χ2=6.71，P<0.05). The rate of SID was 42.1% with no significant gender difference(χ2=7.32，P=0.62). The concordance rate of SID and DCD(23/25，92.0%) was related to family environment for motor development. Specifically, parental rearing patterns was the primary factor for co-occurrence of SID and DCD(B=-0.37, OR=0.69, 95%CI=0.54-0.89，P<0.01).@*Conclusion@#The development of SID and DCD is closely related among preschoolers. Parental rearing pattern plays an important role in SID and DCD.
