Background: Although poor health conditions and decreased developmental levels have been investigated in migrant children, no study in China has focused on these children’s individual motor development. Objectives: This study aims to explore the prevalence of motor impairment in Chinese migrant children and to determine the contributory factors. Patients and Methods: In this cross-sectional study, a structured questionnaire was administered to primary caregivers of preschool children aged 3-6 (n = 2,976) in ten kindergartens from two districts of Suzhou, China, to assess the children’s home socioeconomic status and motor environment, that is, the presence of affordances for motor development. Motor ability was assessed using the Movement Assessment battery for children-second edition (MABC-2). Multiple logistic regression analysis was used to determine the risk factors for motor impairment in migrant children. Results: Migrant children showed correlations with impairment in manual dexterity, aiming and catching, and motor development (odds ratios [ORs] = 1.320, 1.255, 1.260, respectively; P < 0.05). Outdoor movement affordances and toys for fine motor development were significantly associated with motor impairment in migrant children (ORs = 0.834 [movement affordances, 0.843 [toys], P < 0.05). Conclusions: Chinese migrant children are at a high risk of motor impairment, which is associated with a lack of outdoor movementaffordancesandtoys forfinemotordevelopment.
