Incidence and factors associated with hypoglycemia in newly diagnosed hospitalized children and adolescents with type 1 diabetes mellitus in China.

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.
