A survey was conducted at a 526-bed community hospital in Rochester, N
ew York, to determine the prevalence of formula advertising and distri
bution during pregnancy to 136 consecutive intrapartum patients. Women
answered a questionnaire about their choice of infant feeding methods
and prenatal exposure to formula advertising. Of those who received p
rinted information on infant feeding, 78 percent reported that it was
published by a formula company, and 65 percent recalled receiving offe
rs for free formula during their pregnancy. The likelihood of having r
eceived such offers was the same in women who planned to breastfeed as
in those who planned to formula feed. Thirty-eight percent of women o
btained formula through a free offer before their infant's birth. Wome
n who were privately cared for were more likely to have received offer
s for free formula (p <0.001) than were women cared for in hospital-af
filiated clinics. Ninety percent of women who received free formula pr
enatally reported their prenatal caregiver as a source of samples. Of
samples that women obtained prenatally, 93 percent were from companies
that advertise only indirectly through hospitals and physicians, wher
eas 7 percent were from companies that advertise directly to patients.
The prevalence of formula company advertising during the prenatal car
e of women who deliver in this hospital is high. The continued partici
pation of prenatal caregivers in promotion efforts of formula companie
s provides a negative or mixed message about the importance of breastf
eeding and may be a barrier to its success.
