Objective. To determine prevalent infant sleep positions before and af
ter the American Academy of Pediatrics position statement of 1992 and
to identify determinants of sleep position. Method. Design: cross-sect
ional survey. Setting: private and hospital-sponsored general pediatri
c offices. Participants: parents of infants younger than 7 months of a
ge. Results. Eight hundred fifty-two care givers completed surveys dur
ing the 5-week study. Fifty-four percent of the study infants were put
to sleep in the prone position. In 416 families with more than one ch
ild, however, 75% of the youngest siblings had been put to sleep in th
e prone position at the same age. Gender, race, family income, materna
l smoking, and birth weight were not associated with choice of sleep p
