In large epidemiologic studies, information on breastfeeding practice is often collected from maternal recall through interviews, but there is concern about the accuracy of the data, especially when mothers are asked to recall their practices from many years earlier. This review examines the validity and reliability of maternal recall of breastfeeding history using 11 studies published between 1966 and 2003 in English with a sample of 10 or more. Validity is the degree to which recall compares with a validation standard or reference, and reliability refers to the degree to which the breastfeeding practices obtained by recall are repeatable over time. The existing studies suggest that maternal recall is a valid and reliable estimate of breastfeeding initiation and duration, especially when the duration of breastfeeding is recalled after a short period (< or = 3 years). Validity and reliability of maternal recall for the age at introduction of food and fluids other than breast milk are less satisfactory. Further and more extensive studies on maternal recall of breastfeeding history and ways to improve such recall are warranted.
在大型流行病学研究中，母乳喂养情况的信息通常通过访谈由母亲回忆收集，但人们担心数据的准确性，尤其是当母亲被要求回忆多年前的喂养情况时。本综述使用1966年至2003年间发表的11篇英文研究（样本量为10或更多），考察了母亲回忆母乳喂养史的有效性和可靠性。有效性是指回忆与验证标准或参考相比的程度，可靠性是指通过回忆获得的母乳喂养情况随时间的可重复性程度。现有研究表明，母亲回忆是母乳喂养开始和持续时间的有效且可靠的估计，尤其是在短时间内（≤3年）回忆母乳喂养持续时间时。母亲回忆引入母乳以外的食物和液体的年龄的有效性和可靠性则不太令人满意。有必要对母亲回忆母乳喂养史以及改善这种回忆的方法进行进一步和更广泛的研究。
