Weight gain during pregnancy: Does the antenatal care provider make a difference? A retrospective cohort study

Proportions of pregnancies with weight gain below, within and above recommended levels, by antenatal health care provider.

Adjusted relative risk (RR) of being small for gestational age, being large for gestational age, preterm birth and cesarean delivery among pregnancies with a weight below that recommended relative to those with a weight gain within recommended levels, stratified according to antenatal health care provider. Note: CI = confidence interval. *Adjusted for maternal age, parity, gestational age at birth, prepregnancy body mass index (BMI), income quintile, education quintile, smoking, depression, preexisting diabetes, preexisting hypertension and gestational diabetes mellitus. †Adjusted for maternal age, parity, gestational age at birth, prepregnancy BMI, income quintile, education quintile, smoking, preexisting diabetes, preexisting hypertension, gestational diabetes, drug exposure, alcohol consumption, mental illness, previous cesarean delivery, previous term birth, previous preterm birth, previous vaginal birth, previous stillbirth, previous abortion, nonvertex presentation and male infant.

Population attributable fractions of being small for gestational age, being large for gestational age, preterm birth and cesarean delivery for weight gain above that recommended relative to weight gain within recommended levels, stratified according to antenatal health care provider. Note: CI = confidence interval, RR = relative risk.
