METHOD We conducted a cross-sectional study of 4001 preschool children selected from 160classes. The children's motor performance was assessed using the Movement Assessment Battery for Children, 2nd edition (MABC-2). Home and educational environments were evaluated using validated checklists. The effects of home and educational environments on motor performance were analysed using mixed and multilevel logistic regression models.
RESULTSThe results showed that one score increase in the outside space of the family home was positively associated with the increase in total test score (0.104) subtest score of aiming and catching (0.037), and balance (0.034) of the MABC-2, after adjusting for potential confounders (each p<0.05). Possession of motor toys at home and parental rearing behaviours were also related to total test score, manual dexterity, and balance (b=0.022-0.104, each p<0.05). Space and furnishings, activity, and interaction in the classroom had a significant positive association with total test score (b=0.069-0.201), and with subtest scores of manual dexterity, aiming and catching, and balance respectively (b=0.115-0.206). Space and furnishings of classrooms and possession of toys in the household were protective factors for 'at risk' or significant poor performance (odds ratio 0.942-0.973, each p<0.05).
