Mixed-effects multinomial models tested longitudinal associations. Robust clusters were used to control for repeated measures across subjects. All models were adjusted for visit.
Presence of depressive symptoms indicated by score ≥ 16 on the Center for Epidemiological Studies-Depression Scale, measured at each visit.
Model adjusted for visit and study intervention group. Chi-square goodness of fit for multinomial models=p>0.05.
t is the timepoint (i.e., home visit) preceding time t+1; t+1 is the timepoint succeeding time t.
Model adjusted for visit, breastfeeding outcomes (exclusivity and duration), infant distress to limitations, infant activity level, and study intervention group. Chi-square goodness of fit for multinomial models= p>0.05.
