IntroductionMost neonates experience transient hypoglycemia, which typically responds well to treatment and is associated with a favorable prognosis. However, hypoglycemia persisting beyond 48 hours, termed prolonged transitional Neonatal hypoglycemia (PTNHG), can result in abrupt neuronal injury and long-term neurodevelopmental impairments. Identifying its prevalence and associated risk factors is critical to inform clinical practices and improve neonatal outcomes.MethodsA weighted inverse-variance random-effects model was employed for the analysis. Heterogeneity among the studies was assessed using a forest plot, I2 statistics, and Egger’s test. Data extraction was conducted from May 20 to May 27, 2023, for studies published since 2020. A random blood sugar (RBS) concentration of ResultsThe pooled prevalence of PTNHG was 19.71% (95% CI: 16.85–22.56) with substantial heterogeneity (I2 = 79.20%, P 400 and ≤400, at 18% (95% CI: 15–22) and 21% (95% CI: 17–26), respectively. Similarly, prevalence estimates were comparable when using RBS thresholds of ConclusionsNearly one-fifth of hospitalized neonates experienced PTNHG. Fortunately, most of the associated risk factors were modifiable. Prioritizing early breastfeeding initiation, particularly in cesarean section deliveries and IDM cases, and integrating PTNHG management into national NICU guidelines could significantly reduce the burden of neonatal hypoglycemia.Trial registrationProspero ID: CRD42023424953. https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023424953.
