【Objective】 To describe the body shape and motor ability of 2~3 years old children and to discuss the relationships between feeding factors and the two aspects. 【Methods】 149 children aged 2~3 years old were tested on body shape including height,sitting height,weight,and motor ability composed of walking the balance beam,throw for distance,standing long jump,seat proneness,split,shuttle runs,horizontal bar hanging,and so on.Feeding factors were investigated including feeding patterns,children's appetites and months when complementary food was added. 【Results】 Heights of boys were higher than those of girls,but there was no difference on motor ability.Body shape indicators of artificial feeding and mixed feeding groups were higher than those of breast-feeding group.Two pairs of canonical variables were selected by canonical correlation analysis.Height,weight and weight for height played the important role among body shape indicators in canonical variables.Walking the balance beam,throw for distance,standing long jump,split and repeated crossing in 20 seconds,the canonical variables representing the motor ability,played the important role. 【Conclusions】 Feeding factors would make efforts in body shape.Also,correlation is found between body shape and motor ability in 2~3 years old children.
