摘要：This study compares rates of breast feeding reported in the National Surveys of Family Growth with those from the Ross Laboratories Mothers Surveys. Both surveys have documented rates of breast feeding over the last 30 or more years. Despite differences in survey methodology, both surveys document similar long-term trends in breast feeding. The similarities of rates in breast feeding also are evident across several maternal sociodemographic characteristics. We conclude that both surveys produce reliable and useful estimates of breast feeding.
