Low adherence to MDQS is the reference (Ref.) category for diet and adequate RGWG is the reference category for adequacy of GWG in the logistic multilevel model.
a
Adjusted for gestational age.
b
Models adjusted for pre-pregnancy BMI, energy intake, gestational age, maternal age, educational level, parity, fetal sex, marital status and physical activity.
Abbreviations: RGWG: rate gestational weight gain; OR: odds ratio; CI: confidence interval; Pre- BMI: pregestational body mass index.
