背景：许多关于母乳喂养对儿童或孕产妇健康影响的研究都依赖于回顾性报告的数据。本研究的目的是评估回顾性收集的数据，断奶年龄，停止的原因，乳房疼痛，哺乳期乳腺炎，和pumping.Methods：妇女在密歇根州和内布拉斯加州，美国进行了电话采访，每3个星期在第一个3个月后，他们的孩子出生，并在6个月邮寄问卷。出生后约1-3.5年，通过电话再次采访了一个子集。三个回忆期，收集1994-1998年的结果进行了比较，使用相关性，线性和考克斯回归分析，灵敏度和特异性estimation.Results：184名参与者年龄在18-42岁，大多数白色（95%）和63%有一个较大的孩子。与事件发生后3周内的访谈相比，出生后1-3.5年的访谈中断奶年龄往往被高估，1-3.5年的回忆约为1个月，6个月的回忆约为2周（两种情况下p < 0.001）。断奶原因的回忆准确性因原因而异，乳腺炎和返回工作具有最大的回忆效度。1-3.5年的乳腺炎回忆的敏感性为80%，但只有54%的乳头裂缝或sores.Conclusion：母乳喂养的时间在短期母乳喂养者往往有点高估时，测量产后1-3.5年。其他母乳喂养特征的报告具有可变的可靠性。采用回顾性母乳喂养数据的研究应考虑此类错误的可能性。
Background: Many studies of the impact of breastfeeding on child or maternal health have relied on data reported retrospectively. The goal of this study was to assess recall accuracy among breastfeeding mothers of retrospectively collected data on age of weaning, reasons for cessation, breast pain, lactation mastitis, and pumping.Methods: Women in Michigan and Nebraska, U.S.A. were interviewed by telephone every 3 weeks during the first 3 months after the birth of their child, and mailed a questionnaire at 6 months. A subset was interviewed again by telephone approximately 1-3.5 years after the birth. The results for the three recall periods, collected 1994-1998, were compared using correlation, linear and Cox regression analysis, and sensitivity and specificity estimates.Results: The 184 participants were aged 18-42, mostly white (95%) and 63% had an older child. The age of weaning tended to be overestimated in interviews 1-3.5 years after birth compared to those within 3 weeks of the event, by approximately one month for 1-3.5 year recall and two weeks for 6-month recall (p < 0.001 in both cases). Recall accuracy of reasons for weaning varied greatly by reason, with mastitis and return to work having the most recall validity. The sensitivity of 1-3.5 year recall of mastitis was 80%, but was only 54% for nipple cracks or sores.Conclusion: Breastfeeding duration among short-term breastfeeders tended to be somewhat overestimated when measured at 1-3.5 years post-partum. Reporting of other breastfeeding characteristics had variable reliability. Studies employing retrospective breastfeeding data should consider the possibility of such errors.
