Hypoglycemia was defined as blood glucose &lt;3.9 mmol\/L (grade 1: 3.0\u20133.9 mmol\/L; grade 2: &lt;3.0 mmol\/L).Between-group comparisons were performed using independent samples t-test, \u03c72-test, Mann-Whitney U-test, and binary logistic regression analysis to identify factors associated with hypoglycemia.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Among 567 patients, The total number of blood glucose measurements during hospitalization was 50,626.Hypoglycemia (&lt;3.9 mmol\/L) occurred 2,545 times, with an incidence density of 5.03%.Regarding severity 1,995 episodes of grade 1 hypoglycemia occurred(incidence density 3.94%), and 550 episodes of grade 2 hypoglycemia occurred(incidence density 1.08%).In terms of frequency, 81.66% (463\/567) of patients had at least 1 hypoglycemia episode during hospitalization. Among those, 15.87% (90\/567) had one episode, 12.52% (71\/567) had two episodes, and 53.26% (302\/567) had three or more episodes. The recurrence rate (\u22652 episodes) was 65.78%(373\/567 ).Regarding timing, grade 1 hypoglycemia occurred most frequently at night (00:00\u201306:00), while the highest event density for grade 2 was observed in the pre-lunch period (09:00\u201312:00). Multifactorial logistic regression analysis showed that age 7\u201312 years(OR\u00a0=\u00a00.421,95%CI=0.244-0.727,p\n =<\/jats:italic>\n 0.002),longer hospitalization days (OR=1.346,95%CI=(1.217-1.488, p&lt;0.001), use of multiple daily injections (MDI) + continuous subcutaneous insulin infusion (CSII) regimen (OR\u00a0=\u00a03.232, 95%CI=1.399-7.469, p=0.006), fasting C-peptide (OR\u00a0=\u00a00.200, 95%CI=0.076-0.525, p\n =<\/jats:italic>\n 0.001), and fasting insulin (OR\u00a0=\u00a00.938, 95%CI=0.890-0.988, p=0.017) were independently associated with hypoglycemia.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Hypoglycemia is common among newly diagnosed hospitalized children and adolescents with T1DM in China, particularly at night for grade 1 events. Age, hospitalization days, insulin regimen, fasting C-peptide, and fasting insulin were associated with hypoglycemia. These associations, particularly for insulin regimen, should be interpreted considering potential confounding by indication due to the observational study design. These findings may inform targeted prevention strategies.<\/jats:p>\n
