Abstract Objective To investigate the risk factors for hypoglycemia after birth in preterm infants with a gestational age of ≤ 32 weeks. Methods A retrospective analysis was performed for 86 neonates with hypoglycemia and a gestational age of ≤ 32 weeks who were admitted to the neonatal intensive care unit from January 2017 to June 2020 (hypoglycemia group). A total of 172 preterm infants with normal blood glucose who were hospitalized during the same period were randomly enrolled as the control group. Univariate analysis and multivariate logistic regression analysis were used to screen out the risk factors for hypoglycemia in preterm infants. Results There were 515 preterm infants during the study, among whom 86 (16.7%) had hypoglycemia. Compared with the control group, the hypoglycemia group had significantly higher percentages of small for gestational age (SGA), cesarean section, maternal hypertension, and antenatal steroid administration (P < 0.05), but significantly lower birth weight and rate of intravenous glucose use before blood glucose test (P < 0.05). SGA (OR=4.311, 95% CI:1.285-14.462, P < 0.05), maternal hypertension (OR=2.469, 95% CI:1.310-4.652, P < 0.05), and antenatal steroid administration (OR=6.337, 95% CI:1.430-28.095, P < 0.05) were risk factors for hypoglycemia in preterm infants, while intravenous glucose use (OR=0.318, 95% CI:0.171-0.591, P < 0.05) was a protective factor against hypoglycemia in preterm infants. Conclusions SGA, maternal hypertension, and antenatal steroid administration may increase the risk of early hypoglycemia in preterm infants with a gestational age of ≤ 32 weeks, and intravenous glucose use is recommended as soon as possible after birth for preterm infants with a gestational age of ≤ 32 weeks to reduce the incidence rate of hypoglycemia.
