Recent declines in breast-feeding in the United States, 1984 through 1989

Ongoing surveys performed by Ross Laboratories demonstrate recent declines both in the initiation of breast-feeding and continued breast-feeding at 6 months of age. Comparing rates in 1984 and 1989, the initiation of breast-feeding declined approximately 13% (from 59.7% to 52.2%), and there was a 24% decline in the rate of breast-feeding at 6 months of age (from 23.8% to 18.1%). The decline in breast-feeding was seen across all groups studied but was greater in some groups than in others. Logistic regression analysis indicates that white ethnicity, some college education, increased maternal age, and having an infant of normal birth weight were all positively associated with the likelihood of both initiating breast-feeding and continuing to breast-feed to at least 6 months of age. Women who were black and who were younger, no more than high school educated, enrolled in the Women, Infants and Children supplemental food program, working outside the home, not living in the western states, and who had an infant of low birth weight were less likely either to initiate breast-feeding or to be nursing when their children were 6 months of age. The factors influencing the decline in breast-feeding were not uniform. There were fewer sociodemographic factors associated with the decline in the initiation of breast-feeding than in the decline in prolonged breast-feeding. While the disparity between older and younger mothers in initiating breast-feeding increased, there was an offsetting trend as the disparity associated with parity decreased.
