In this study, 915 children aged 1 to 3 years in urban and rural areas of Hubei Province were enrolled in this study. The factors affecting their intelligence development were analyzed by single factor and multiple stepwise regression analysis. The results showed that the main factors influencing the mental development of young children in rural areas were the educational level of mothers and caregivers, the weaning month of young children, the time of complementary feeding and the level of iron intake. Toddler height, upper arm circumference, Wilkens index and other contrasts also have a certain impact. The main influencing factors of mental development of preschool children in urban areas are the level of maternal education, the age of maternity, the occupation of fathers and the time of complementary feeding.
