Abstract Objective To analyze the effects of the weight changes during pregnancy of gestational diabetes mellitus on neonatal birth weight. Methods From January to December 2016, in Tongzhou Maternal and Child Health Hospital of Beijing, the dates of 1240 pregnant woman with gestational diabetes mellitus and complete single birth and complete medical records were retrospectively. They were divided into(BMI <18.5 kg/m2, groupⅠ), normal body weight group (BMI 18.5-<24.0 kg/m2, groupⅡ),overweight group (BMI 24.0-<28.0 kg/m2, groupⅢ), obese (group B), obesity group (BMI≥28.0 kg/m2, group Ⅳ). They were divided into groupⅠ+Ⅱ and group Ⅲ+Ⅳ, because of the low proportion of low weight group. The effects of the weight changes of gestational diabetes mellitus on neonatal birth weight in two groups were compared. Results In groupⅠ+Ⅱ and group Ⅲ+Ⅳ, the weight [(61.41±4.34) vs (70.41±3.90) kg], pre-pregnancy BMI [(22.34±3.19) vs (26.79±3.72)kg/m2], body weight gain during pregnancy [(16.08±5.42) vs (12.55±6.59) kg], neonatal body weight [(3414.2±460.7) vs (3480.1±542.7) g] were compared, the differences were statistically significant (P < 0.05). In groupⅠ+Ⅱpregnancy weight gained≥20 kg, the risk of LGA increased (P < 0.05); pregnancy weight gained 2.5-< 10.0 kg, SGA increased risk (P < 0.05); in group Ⅲ+Ⅳ: gestational weight gained≥12.5 kg, LGA increased risk (P < 0.05); pregnancy weight gained 2.5-<7.5 kg, SGA increased risk (P < 0.05). Conclusion In the management of gestational diabetes, blood glucose should be monitored at the same time, it should pay attention to the management of its weight, the weight of the changes in the weight of newborns have a significant impact on low birth weight and normal weight of gestational diabetes maternal pregnancy weight gain should be controlled at 10-20 kg, for pre-pregnancy overweight and obese gestational diabetes mellitus pregnancy weight gain should be controlled at 7.5-12.5 kg.
