• The effect of air pollution on human health has been a major concern, especially the association between air pollution and gestational diabetes mellitus (GDM). In this study, we conducted a retrospective cohort study in Taiyuan, a typical energy production base in China. This study included 28,977 pairs of mothers and infants between January 2018 and December 2020. To screen for GDM, oral glucose tolerance test (OGTT) was performed in pregnant women at 24–28 weeks of gestation. Logistic regression was used to assess the trimester-specific association between 5 common air pollutants (PM10, PM2.5, NO2, SO2, and O3) and GDM, and the weekly-based association was also assessed using distributed lag non-linear models (DLNMs). Odds ratios (ORs) with 95 % confidence intervals (CIs) were calculated for the association between GDM and each air pollutant. The overall incidence of GDM was 3.29 %. PM2.5 was positively associated with GDM over the second trimester (OR [95 % CI], 1.105 [1.021, 1.196]). O3 was positively associated with GDM in the preconception period (OR [95 % CI], 1.125 [1.024, 1.236]), the first trimester (OR [95 % CI], 1.088 [1.019, 1.161]) and the 1st + 2nd trimester (OR [95 % CI], 1.643 [1.387, 1.945]). For the weekly-based association, PM2.5 was positively associated with GDM at 19–24 weeks of gestation, with the strongest association at week 24 (OR [95 % CI], 1.044 [1.021, 1.067]). PM10 was positively associated with GDM at 18–24 weeks of gestation, with the strongest association at week 24 (OR [95 % CI], 1.016 [1.003, 1.030]). O3 was positively associated with GDM during the 3rd week before conception to the 8th gestational week, with the strongest association at week 3 of gestation (OR [95 % CI], 1.054 [1.032, 1.077]). The findings are important for the development of effective air quality policies and the optimization of preventive strategies for preconception and prenatal care. [Display omitted] •PM10 and PM2.5 exposure increased GDM during 18/19–24 weeks of gestation.•O3 was highly associated with GDM during preconception and early gestation.•NO2 and SO2 had no association with GDM.
