Main Outcome Measures The position the infant was usually placed in for sleep, sleep position recommendations received from specific sources, and reasons reported for position choice. Results Between 1994 and 1998, prone placement declined from 44% to 17% among white infants and from 53% to 32% among black infants. Supine placement increased from 27% to 58% among white infants and from 17% to 31% among black infants. During this period, reports of supine recommendations from at least 1 source doubled from 38% to 79%.
