Objective To investigate the influence factors of hypoglycemia in children with type 1 diabe⁃ tes. Methods Clinical data of 542 children with type 1 diabetes hospitalized from January 2017 to December 2019 were collected，and the influence factors of hypoglycemia were analyzed. Results Blood glucose control rate of diabetic children was 22.0%；incidence of hypoglycemia 60.89%and occurrence density of hypoglycemia 3.89%. The period before meals witnessed high incidence of hypoglycemia in children. The incidence of hypoglycemia in children with type 1 diabetes was influenced by the age of the child，newly⁃confirmed case，and HbAlc（P < 0.05）. Multivariate logistic showed that age was a protective factor for reducing hypoglycemia，while newly⁃confirmed case risk factor for hypoglycemia. Conclusion The incidence of hypoglycemia in children with type 1 diabetes remains high，and the rate of blood glucose control is low. Young children and newly⁃diagnosed children are at a high risk of hypoglycemia.
