The present study aimed to determine the factors that contribute to the delivery of overweight babies by pregnant women who have not been diagnosed with an abnormal glucose metabolism. From 273 delivery cases in fiscal year 2021 at one acute care hospital, the pregnant women of group A （24 cases who delivered a baby weighing 3,500 g or more） and group B （192 cases who delivered a baby weighing 2,500–3,499 g） were compared, excluding the pregnant women who delivered stillbirth, multiple births, a baby weighing less than 2,500 g, and those with an abnormal glucose metabolism. Group A had a later delivery week （p < 0.001），a higher nongestational BMI （p = 0.028），and higher initial blood glucose （p = 0.037） than group B. The neonatal weight correlated with the week of delivery and the non-pregnancy BMI. A multivariate analysis revealed the factors contributing to the delivery of overweight babies to include a delay in the number of weeks of delivery, a high non-gestational BMI, a high initial blood glucose level, and a history of infertility treatment （odds ratio ［95％CI］:2.46 ［1.46-4.15］, 1.20 ［1.07-1.35］, 1.06 ［1.00-1.12］, 5.91 ［1.26-27.60］）.
The necessity to develop preventive intervention strategies while considering the various risk factors of overweight babies was indicated, even when the mother has not been diagnosed to have any glucose metabolism abnormality.
