Background. Physician support has been shown to increase breast-feedin
g rates, but anecdotal reports suggest that physicians are ill prepare
d for their role in breast-feeding promotion. Inadequate breast-feedin
g education during residency training may be a contributing Factor. Me
thods. A self-administered questionnaire Ii-tailed to 1099 family medi
cine residents and 665 recently board-certified family physicians asse
ssed knowledge, attitudes, education, and activity related to breast-f
eeding promotion. Response rates were 71% for residents and 58% for ph
ysicians. Results. Although residents and physicians were strongly con
vinced that family physicians should be involved in breast-feeding pro
motion, both groups demonstrated significant deficits in know ledge ab
out breast-feeding benefits and clinical management strategies. Common
errors included inappropriate recommendations for breast-feeding term
ination or formula supplementation, a proven cause of breast-feeding f
ailure. Personal breastfeeding experience was the only factor consiste
ntly associated with more frequent breast-feeding promotion activity a
mong residents and increased self-confidence for both groups. Responde
nts reported only limited opportunities for developing breast-feeding
counseling skills during residency training. Conclusions. Improved bre
ast-feeding education is needed for family medicine residents and phys
icians. Residency training and continuing education programs should em
phasize the benefits of breast-feeding, clinical management strategies
, and development of practical counseling skills.
