Gestational diabetes mellitus (GDM) is on the rise in the world and Vietnam. Primary intervention was a modest diet; some recent
studies have documented the high blood glucose level in 75 grams glucose tolerance testing associated with simple dietary control
failure. Objectives: To determine the relationship between the level fasting plasma glucose in 75 grams of glucose tolerance test and
the needs of insulin therapy in gestational diabetes mellitus at the Department of High-Risk pregnancy, Hung Vuong hospital.
Methods: A nested case-control study including 160 pregnant women with GDM treated at the Department of High-Risk pregnancy,
Hung Vuong Hospital, HCMC from 11/2017 to 11/2019, were eligible for sampling and consent to participate. Results: Fasting
plasma glucose, 1 hour after ingestion, and 2 hours after ingestion in the 75 grams glucose test were significantly higher in the
gestational diabetes mellitus group with insulin compared with the control group diet. Conclusion: Fasting plasma glucose values in
the 75-gram glucose test - 2 hours can help predict the need for insulin in pregnant women with GDM.
