IntroductionStudies on the relationship between environmental tobacco smoke (ETS) and gestational diabetes mellitus (GDM) are limited. In this study, we aimed to clarify the association between ETS at different trimesters of pregnancy and the risk of GDM among non‐smoking pregnant women.MethodsA total of 16,893 non‐smoking mothers from the Southwest Birth Cohort, China, were included in the final analyses. Exposure and outcome measures included self‐reported ETS status at different trimesters of pregnancy and GDM diagnosis. Multivariable logistic regression models were constructed to estimate the association between ETS and GDM.ResultsThe prevalence of ETS exposure was 25.7%. Compared with no ETS, ever ETS had an increased risk of GDM, with an adjusted odds ratio (95% confidence intervals) of 1.21 (1.09, 1.33). The association remained consistent at different trimesters of pregnancy ETS exposure. In the last trimester and with continuous ETS exposure, the risk of GDM increased significantly with the increase in the duration of the exposure. The risk of GDM associated with ever ETS during pregnancy significantly increased in mothers over 30 years old and pre‐pregnancy overweight (P for interaction <0.05).ConclusionsETS exposure at different trimesters of pregnancy was associated with an increased risk of GDM among non‐smoking pregnant women. These findings emphasise the importance of preventing ETS exposure during pregnancy.
