Objective:
To determine whether vulnerability factors (confidence with breastfeeding, postpartum depression, supplementation, and perceived adequacy of support) are associated with breastfeeding outcome at 6 weeks postpartum after controlling for age and education.
Design:
Secondary analysis of a cross-sectional telephone survey at 6 weeks postpartum.
Setting:
Ottawa-Carleton, Ontario, Canada.
Participants:
A proportionate, consecutive sample of breastfeeding women from each of four hospitals in the region (526/554, 95% response rate).
Methods:
Stratified bivariate analyses were used to examine the relationship between each factor and breastfeeding outcome. Multivariate logistic regression analyses examined relationships between all factors and breastfeeding outcome.
Results:
In the logistic regression analyses, confidence with breastfeeding (odds ratio: 1.85, 95% confidence interval: 1.50-2.27, p < .001) and postpartum depression (odds ratio: 0.28, 95% confidence interval: 0.11-0.71, p= .007) were related to breastfeeding after controlling for age and education.
Conclusions:
Support for breastfeeding should include assessment of maternal confidence with breastfeeding and postpartum depression. Evaluation of intervention strategies to address these vulnerability factors is a priority.
