High physical activity and high sedentary behavior increased the risk of gestational diabetes mellitus among women with excessive gestational weight gain: a prospective study

Table 2 Adjusted odds ratios and 95% confidence intervals for GDM risk among physical activity trajectory groups (N = 452)

Physical activity trajectory groups	GDM

Note. Non-GDM as reference
Model 1: Adjusted for gestational week at the time of blood sampling

Model 3: Adjusted for covariates in model 2 + parity + pre-pregnancy BMI + rate of GWG in the second trimester
