ABSTRACT
OBJECTIVES:
To examine whether use of expressed human milk in the first two weeks postpartum is associated with cessation of human milk feeding and non-exclusive human milk feeding up to 6 months.DESIGN:
Pooled data from two prospective cohort studiesSETTING:
Three Canada Prenatal Nutrition Program (CPNP) sites serving vulnerable families in Toronto, Canada.PARTICIPANTS:
337 registered CPNP clients enrolled prenatally from 2017 to 2020; 315 (93%) were retained to 6 months postpartum. EXCLUSIONS pregnancy loss or participation in prior related study; Study B preterm birth (<34 weeks); plan to move outside Toronto; not intending to feed human milk; hospitalisation of mother or baby at 2 weeks postpartum. PRIMARY AND SECONDARY OUTCOMEMEASURES:
Main exposure variable any use of expressed human milk at 2 weeks postpartum.OUTCOMES:
cessation of human milk feeding by 6 months; non-exclusive human milk feeding to 4 months and 6 months postpartum.RESULTS:

At 2 weeks postpartum, 34% reported use of expressed human milk. Any use of expressed human milk at 2 weeks was associated with cessation of human milk feeding before 6 months postpartum (aOR 2.66; 95% CI 1.41 to 5.05) and with non-exclusive human milk feeding to 4 months (aOR 2.19; 95% CI 1.16 to 4.14) and 6 months (aOR 3.65; 95% CI 1.50 to 8.84).
