a
Data taken from the Infant Feeding Practices Survey II. Prevalence estimate and 95% CI per 100 women, using multiple imputation for missing data.
b
OR from logistic regression for disrupted lactation vs. referent group that did not meet criteria for disrupted lactation (n=2,055).
c
MV-adjusted models include WIC status, marital status, race/ethnicity, maternal age, parity, and education.
d
OR from multinomial regression for early, undesired weaning vs. referent group with breastfeeding ≥12 months (n=434).
BMI, body mass index; EPDS, Edinburgh Postnatal Depression Scale; MV, multivariable; OR, odds ratio.
