Encouraging direction, but not yet definitive.
This retrospective observational study of 458 women with gestational diabetes identifies independent factors associated with antenatal insulin therapy requirement, including pre-pregnancy obesity, miscarriage history, pregestational hypothyroidism, and OGTT-based GDM phenotype. Women with combined hyperglycaemia (fasting and post-load) face nearly twofold increased risk of insulin use compared to isolated fasting hyperglycaemia, suggesting OGTT phenotype classification may help individualise management decisions.
Retrospective observational study. Women with diagnosed gestational diabetes mellitus; stratification by OGTT-based phenotype and treatment modality. Intervention: Insulin therapy. Compared with: Nutritional therapy alone. n = 458.
39.3% of 458 women required insulin therapy Pre-pregnancy obesity associated with insulin therapy (OR 2.07, 95% CI: 1.21–3.55) Spontaneous miscarriage history associated with insulin therapy (OR 1.89, 95% CI: 1.21–2.93)
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Clinicians managing GDM may use OGTT-based phenotype classification alongside clinical risk factors (obesity, hypothyroidism, miscarriage history) to stratify insulin therapy requirement; combined hyperglycaemia signals higher need for insulin, whereas isolated post-load hyperglycaemia suggests lower risk. This observational finding should be validated in prospective studies before routinely embedding it in decision algorithms.
Retrospective observational study identifying clinical and biochemical factors associated with insulin use in GDM using multivariable logistic regression; sound methodology with clear effect estimates but limited by observational design and lack of hard clinical outcomes.

Abstract Gestational diabetes mellitus (GDM) represents one of the most common metabolic disorders of pregnancy. This study aimed to identify clinical and biochemical factors associated with antenatal insulin therapy, focusing on the association with oral glucose tolerance test (OGTT)‐based phenotypes. Retrospective observational study among GDM women, divided according to their treatment (nutritional therapy (NT) or insulin therapy). GDM was classified into three phenotypes based on OGTT results: isolated fasting hyperglycaemia (IFH‐GDM), isolated post‐load hyperglycaemia (IPH‐GDM) and combined hyperglycaemia (CH‐GDM). Maternal demographic, obstetric and biochemical data were analysed. Multivariable logistic regression analysis was performed to identify factors independently associated with insulin therapy. Among 458 women, 39.3% required insulin therapy. Independent factors associated with the use of insulin therapy included pre‐pregnancy obesity (odds ratio (OR) 2.07, 95% CI: 1.21–3.55), spontaneous miscarriage history (OR 1.89, 95% CI: 1.21–2.93), pregestational hypothyroidism (OR 2.63, 95% CI: 1.08–6.42), GDM diagnosis at 24–28 weeks versus earlier diagnosis (OR 0.45, 95% CI: 0.28–0.72), and GDM phenotype. Compared with IFH‐GDM, IPH‐GDM was associated with a lower risk of insulin therapy (OR 0.51, 95% CI: 0.31–0.84), whereas CH‐GDM was associated with a higher risk (OR 1.90, 95% CI: 1.10–3.31). In conclusion, women with fasting and combined hyperglycaemia represent the highest‐risk group for insulin therapy. Integrating OGTT‐based phenotypes with clinical risk factors was associated with increased likelihood of insulin therapy requirement and may support individualized clinical assessment.
