Abstract: Objective: To observe the effect of passive smoking during pregnancy on patients with gestational diabetes mellitus. Methods: The data of 177 patients who continued to participate in "one day outpatient service of gestational diabetes mellitus" was collected. According to whether passive smoking during pregnancy was divided into passive smoking group and non-passive smoking group, two groups of patients received the same " one day clinic for gestational diabetes " interventions. The fasting blood-glucose（FPG）,2 hours postprandial blood glucose（2hPG）, glycated hemoglobin (HbAlc), maternal outcomes and infant condition were analyzed. Results: The passive smoking rate during pregnancy among women with gestational diabetes mellitus was 45.20%. There was no significant difference in FPG、2hPG、HbAlc in the two groups before interventions (P>0.05), but there was difference after 2 months of interventions（P<0.05）. There was no significant difference in delivery weeks, polyhydramnios, oligohydramnios, postpartum hemorrhage and preeclampsia between two groups (P>0.05), and there was statistical significance difference in delivery route and pregnancy-induced hypertension(P<0.05),There was no significant difference in rate of neonatal gender, length, 5-minute Apger score, hypoglycemia, malformation, hypocalcemia and asphyxia between two groups(P>0.05),and there was a statistically significant difference in neonatal body mass and rate of macrosomia (P<0.05). Conclusion: Passive Smoking during pregnancy is one of the risk factors affecting blood glucose control in patients with gestational diabetes mellitus, smoke environmental exposure is not conducive to disease control, and it is easy to lead to adverse maternal and child outcomes.
