Mothers were breastfeeding at 6 months of age between 1989 and asked to recall the type of milk fed to their infant in the 1995, following a sharp decline in breastfeeding from hospital, and during each month of age. Two categories of breastfeeding were considered: breastfeeding (human 1984 –1989.

  • 3. Since 1997, the RLMS averaged 33 000 completed question- naires each month (28% response rate). To ensure that all geo- graphical areas are represented and to adjust for difference re- sponse rates, regions of the country where the response rates were low were oversampled. To maintain consistency, the question included in the RLMS, with respect to milk feeding, has not changed markedly over time. From a list of all commercial infant formulas, human milk, and cow’s milk (whole, 2%, etc) mothers were asked to indicate the type of milk fed to their infant “in the hospital,” “at 1 week of age,” “in the last 30 days.” and “most often in the last week.” The “in the hospital” category was used to determine infant feeding practices initiated at birth. The “most often in the last week” category was used to determine the types(s) of milk fed to a 6-month-old infant. The list of infant formulas is updated as new formulas are introduced or removed from the marketplace. Each mother was also asked to answer questions describing her socio- demographic status. Following the approach taken in previous publications,1– 8 the rates of breastfeeding in the hospital and at 6 months of age were evaluated. The present study provides breastfeeding data for 1996 and 2001, with some additional information on trends since 1965. Fig 1.

The weights that were used corresponded to the socio- demographic variables that have historically been associated with breastfeeding. The weights for these variables were derived from the National Center for Health Statistics.9,10 A z statistic was produced to test for significant increases in rates of breastfeeding between 1996 and 2001 in each sociodemo- graphic subgroup. An absolute value of z 1.65 for a 1-tailed test (P .05) was considered to be unlikely to have occurred by chance.11 RESULTS Trends in Breastfeeding and Exclusive Breastfeeding From 1965–2001 As shown in Fig. 1, initiation of breastfeeding and exclusive breastfeeding increased from 1971 to a high point in 1982 (61.9% and 55.0%, respectively). The prevalence of the initiation of breastfeeding and ex- clusive breastfeeding declined from 1983 to 1989. Since 1990, the prevalence of the initiation of breast- feeding dramatically increased 35%, from 51.5% in 1990 to 69.5% in 2001, reaching the highest level Fig 2.
