Objective The study aims to investigate the relationship between maternal prepregnancy body mass index(BMI), physical activity during pregnancy and the gestational diabetes mellitus (GDM). Methods A birth cohort study,which including 6 211 pregnant women with single birth, was conducted from March 2012 to December 2014 in the First Affiliated Hospital of Shanxi Medical University. Information on birth outcomes and maternal complications were abstracted from medical records. Multivariate unconditional logistic regression models were employed to estimate the associations between pre-pregnancy BMI and GDM. Results A total of 16.02%(995/6 211) women were diagnosed with GDM. The risk of GDM in obese and overweight pregnant women was higher than that in normal BMI pregnant women (OR=2.288,95% CI:1.946-2.691), but the risk of GDM in underweight pregnant women was lower (OR=0.692,95%CI:0.541-0.885). The association between physical activity during pregnancy and the risk of GDM had not been found. We also did not observe significant interactions between pre-pregnancy BMI and physical activity during pregnancy (OR=0.899,95% CI:0.370-1.534). Conclusions High pre-pregnancy BMI may be a risk factor of GDM, and keeping normal pre-pregnancy BMI is a better way to prevent GDM.
