Participants were categorized into three groups: GDM (n = 90), PGDM (n = 80), and healthy controls (n = 110) . Nutritional status was assessed using the Controlling Nutritional Status (CONUT) and Prognostic Nutritional Index (PNI) scores. Inflammatory indices including NLR, SII, SIRI, PIV, and others were calculated. Perinatal outcomes such as preterm birth, NICU admission, and Composite Adverse Perinatal Outcomes (CAPO) were recorded. ROC analysis was used to determine the predictive power of the biomarkers.  \nResults The PGDM group demonstrated significantly higher CONUT scores and lower PNI scores compared to the other groups (p \u003C 0. 001) . Among inflammatory markers, NLR, SII, SIRI, and PIV were significantly elevated in PGDM cases. ROC analyses revealed that the CONUT score had strong discriminative ability in differentiating diabetic (GDMand PGDM) from non-diabetic pregnancies (AUC = 0 . 787; specificity = 89 . 1%), while the PNI score showed limited discriminative capacity (AUC = 0 . 291) . Inflammatory indices also demonstrated moderate predictive value, particularly among PGDM cases. Higher CONUT and inflammatory scores were associated with increased rates of preterm birth, NICU admission, and CAPO (p \u003C 0. 001) .  \nConclusion Nutritional and inflammatory disturbances are more prominent in PGDM than in GDM. The CONUTscore and selected inflammatory indices may serve as valuable tools for early risk stratification in diabetic pregnancies. Integration of these parameters into clinical decision-making may improve perinatal outcomes, particularly in highrisk groups such as PGDM.  \nKeywords Gestational diabetes, Pregestational diabetes, CONUT score, Inflammatory indices, Pregnancy outcomes, Perinatal prognosis  \n*Correspondence: Mustafa Rasit Ozler[m.rasitozler@gmail.com](m.rasitozler@gmail.com)  \n1Department of Obstetrics and Gynecology, Division of Perinatology, , Bursa City Hospital, Bursa, Turkey  \n2Department of Obstetrics and Gynecology, Perinatology Unit, Faculty of Medicine, Uludag University, Bursa, Nilüfer 16100, Turkey  \n© The Author(s) 2025.
