Previous studies have indicated that GDM can be effectively managed through antenatal care and lifestyle interventions. This study aims to explore whether GDM still remains a risk factor for adverse neonatal outcomes among multiparous women after the implementation of the universal two-child policy and the enhancement of antenatal care in China.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A total of 7,496 multiparous women were categorized into four groups: those without any complications, those with GDM only, those with non-GDM complications, and those with both GDM and non-GDM complications. Logistic regression models were employed to calculate the adjusted odds ratio (aOR) and its 95% confidence interval (CI) for each outcome. Stratified analysis (based on maternal age) and sensitivity analysis (restricted to multiparas with GDM and\/or hypertensive disorders in pregnancy) were carried out to evaluate the robustness of the results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Compared to infants born to multiparous women with GDM alone, infants born to multiparas without any complications had lower risks of preterm birth (PTB) (aOR 0.57, 95% CI 0.46\u20130.70), macrosomia (aOR 0.60, 95% CI 0.43\u20130.83), large for gestational age (aOR 0.53, 95% CI 0.44\u20130.61). When considering multiparous women with GDM with non-GDM complications, the offspring had higher risks of PTB (aOR 1.98, 95% CI 1.33\u20132.96), LBW (aOR 2.49, 95% CI 1.54\u20134.01), and small for gestational age (aOR 4.82, 95% CI 2.41\u20139.65).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Despite advancements in China's prenatal care system following the two-child policy, GDM persists as a modifiable, high-impact risk factor for neonatal adverse outcomes in multiparous women. Crucially, the synergistic effects of GDM with other pregnancy complications amplify these risks, necessitating early screening (e.g., first-trimester glucose profiling), intensified glycemic management protocols, and family-centered interventions tailored to China's unique sociodemographic landscape.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fped.2025.1573470","type":"journal-article","created":{"date-parts":[[2025,6,13]],"date-time":"2025-06-13T05:51:30Z","timestamp":1749793890000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Gestational
