Abstract: 【Objective】 To investigate the characteristics of anorectal motility spectrum and the risk factors of functional constipation (FC) children,and in order to provide a scientific basis of etiology and precaution for children. 【Method】 Compare the characteristics of anorectal motility spectrum of FC children and healthy children,and the clinical data of these children diagnosed FC were analysed. 【Results】 No statistical differences were found in the anorectal stationary pressure of between two groups.But maximal systolic pressure and maximal tolerated volume between the two groups were significantly different.Factors including the poor balanced diet,excessive intake of fried food,excessive intake of meat,obesity,genetic genes,did not eat or occasionally some vegetables were significantly associated with the presence of chronic constipation. 【Conclusions】 Abnormal features exit in the anorectal motility spectrum of the children with functional eonstipation.Take some target actions and make early treatment could protect children from FC.
