This paper presents results of surveys conducted continuously during a period of years to assess the trend in the incidence of breast-feeding. From 1955 to 1984, questionnaires were mailed to a large nationally representative sample of mothers to determine the use of various milks for feeding infants during the first 6 months of life. Data from these surveys demonstrated the resurgence of breast-feeding both in incidence and duration through 1982. From 1982 through 1984, these increases continued but at a markedly reduced level.
本文呈现了多年来持续进行的调查结果，以评估母乳喂养率的趋势。1955年至1984年期间，向全国具有广泛代表性的大量母亲样本邮寄了调查问卷，以确定在婴儿出生后的前6个月中使用各种奶类进行喂养的情况。这些调查数据显示，到1982年，母乳喂养在发生率和持续时间上均出现了回升。从1982年到1984年，这些增长仍在继续，但幅度明显减小。
