PROJECT SUMMARY/ABSTRACT Breastfeeding in the US has radically changed over the past two decades: feeding at the breast was once the norm, but now more than 85% of infants fed human milk are fed expressed milk from a bottle at least some of the time, and 5-7% of human-milk fed infants are never fed at the breast at all. Data from national surveys are routinely used to inform and evaluate breastfeeding promotion efforts at the national and local levels and are also the basis for research, but the questions currently in use in NCHS surveys no longer reflect contemporary infant feeding and lactation practices and result in significant measurement error. Our long-term goal is to contribute a new understanding of the impact of contemporary infant feeding and lactation practices on maternal and child health. Our objective here, which is the next step towards that goal, is to develop and evaluate a brief set of survey questions to accurately capture these practices among respondents. We will meet this objective by building on our prospective Moms2Moms study to survey mothers of children aged 0-5 years. Our objective was formulated based on our preliminary data revealing that up to 19% of children in our Moms2Moms study would have been misclassified as “not breastfed” or had human milk feeding duration values that were under/overestimates of greater than 1 month if the NCHS questions had been used rather than our pilot survey questions. The rationale for the proposed project is to support future, high-quality research and public health surveillance of maternal and child health which use federal survey data. We plan to attain our objective by pursuing the following Specific Aims: 1) Develop and evaluate a concise set of survey questions about lactation and infant feeding that reflect contemporary practices, and 2) Ensure any recall bias imposed by our question set is equivalent to or less than the bias imposed by the questions currently used in NCHS surveys. The approach will include 3 phases: Pretest, Cross-sectional Field Test, and Comparison with Prospective Data. The proposed research is innovative because it will proactively address pitfalls by systematically pre-testing our question set before fielding with respondents, it will formally test our question set against the existing NCHS questions for direct comparison, and it will directly estimate recall bias by comparing responses to our question set to prospective data collected with the same respondents 4 years' previous. Through the research proposed in this application, we expect to contribute a new, concise, field-tested set of questions that may be used in NCHS surveys and also non-federal surveys. This contribution is significant because it will have a direct, positive impact on the quality of the data produced by these surveys, and thereby, a positive impact on the quality of research and surveillance efforts that rely on these data.

项目摘要/摘要 在过去的二十年中，美国的母乳喂养发生了根本性的变化：乳房喂食曾经是 规范，但现在有85％以上的喂养牛奶的婴儿是从瓶子中喂养牛奶的至少一些 时间和5-7％的人乳喂养婴儿从来没有在乳房中喂食。来自国家调查的数据是 通常用来告知和评估国家和地方一级的母乳喂养促进工作，并且是 这也是研究的基础，但是NCHS目前正在使用的问题不再反映当代 婴儿喂养和哺乳实践，并导致重大的测量误差。我们的长期目标是 对当代婴儿喂养和泌乳实践的影响有了新的了解 母亲和儿童健康。我们的目标是朝着该目标迈出的下一步，是发展和 评估一组简短的调查问题，以准确捕获受访者中的这些做法。我们将 通过基于我们潜在的MOMS2MOMS研究来满足这一目标，以调查年龄在0-5岁的儿童的母亲 年。我们的目标是根据我们的初步数据提出的，表明我们的儿童中有多达19％ MOMS2MOMS研究本来会被错误分类为“不母乳喂养”或喂入人牛奶的持续时间 如果使用NCHS问题，则低于/高估了1个月的值 比我们的试点调查问题。拟议项目的理由是支持未来，高质量 使用联邦调查数据的孕产妇和儿童健康的研究和公共卫生监视。我们计划 通过追求以下特定目标来实现我们的目标：1）开发和评估一套简洁的调查集 关于反映当代实践的哺乳和婴儿喂养的问题，以及2）确保任何回忆偏见 我们的问题集施加的相当于或少于当前使用的问题所施加的偏见 NCHS调查。该方法将包括3个阶段：预测试，横截面测试，并与 前瞻性数据。拟议的研究具有创新性，因为它将主动解决 在与受访者签署之前，系统地对我们的问题集进行了预测试，它将正式测试我们的问题集 针对现有的NCHS问题进行直接比较，它将通过比较直接估计召回偏见 对我们的问题的回答是对以相同回答收集的前瞻性数据进行的4年回答。 通过本申请中提出的研究，我们希望为一组新的，简洁的现场测试集 NCHS调查和非联邦调查中可能使用的问题。这项贡献很重要 因为它将对这些调查产生的数据的质量产生直接的积极影响，从而 对依赖这些数据的研究和监视工作质量的积极影响。
