However,most children with IBD have a low degree of readiness during the transition period,which seriously affects the prognosis and quality of life of children. This paper reviews the research progress on the domestic and foreign status of transition readiness for children with IBD,influencing factors,defects and intervention strategies. Suggestions,shortcomings in current research and practice are put forward,aiming to carry out relevant research for our country in the future and provide references to improve the transition readiness of children with IBD to adults.
