This study describes factors influencing infant feeding choices of 434 moth
ers with 9-month-old infants in Vancouver. Consistent with Social Cognitive
Theory, both internal personal and socio-environmental factors influence i
nfant feeding choices. Mothers attributed the choice to breastfeed primaril
y to personal choice, whereas the choice to formula feed was attributed to
socio-environmental factors. Among mothers who breastfed <3 months, the cho
ice to ean was primarily attributed to concern for baby's nutrition; compar
ed to returning to work, concern about milk supply and concern for baby's n
utrition among those who breastfed greater than or equal to 3 to <6 months;
and returning to work and personal choice among those who breastfed greate
r than or equal to 6 months. Among Caucasian mothers, the choice to wean wa
s primarily attributed to returning to work, compared to concern for baby's
nutrition among non-Caucasian mothers. Initiatives to facilitate further a
dvances in breastfeeding promotion could address three areas; 1) prenatal i
ntentions, 2) early postpartum concerns, and 3) later issues surrounding re
turning to work and infant nutrition.
