The average ICFI score of infants was （8.31 ± 2.05）, which was hyper-mean level. The results of multiple linear analysis showed that the ICFI scores of infants who lived in cities （β’=0.233） and those of 12-24 months old （β’=0.316） and mothers with master’s degree or above （β’=0.166） had higher ICFI scores.
