Objective To explore the influencing factors for developmental level and delay of the infant's gross motor, in order to provide reference for targeted prevention and intervention approaches. Methods A total of 653 healthy infants aged 3~4 months were selected as participants from May to September in 2015. The Ages & Stages Questionnaires Third Edition (Chinese Version) was used to assess gross motor development of infants, and the participants were divided into suspected abnormalities group and normal developing group according to results of assessment .The affordances in the Home Environment for Motor Development-Infant Scale instrument was adopted to assess the home support environment. Results The mean score of gross motor in 653 infants was 49.16±11.41, and 93 cases(14.2%) were identified with suspected developmental delays. After adjusting variables including city, maternal education, marital status and family structure,the appropriate level(β=4.255,95%CI:2.013~6.492) and sufficient level(β=3.010,95%CI:0.845~5.171)of activity space affected the gross motor significantly(both P＜0.05). After adjusting variables like city and marital status, the adequate activity space(OR=0.357, 95%CI: 0.195~0.653),appropriate activity space(OR=0.476, 95%CI: 0.272~0.783),and appropriate variety of stimulation(OR=0.507, 95%CI: 0.288~0.893) were related to suspected gross motor developmental delays. Conclusions Adequate or appropriate activity space, appropriate variety of activities could promote the development of gross motor. Child healthcare providers need to strengthen healthy education and guide parents to improve their home support environment so as to promote early childhood development.
