Timing of prenatal care has become the most widely used indicator of adequacy of care, largely because it is easy to measure and is obtained by national data collection sources. Because it is a crucial input into setting policy goals, it is important that we have an accurate measure of timing of care. This article reviews the existing level of access to prenatal care, as measured by three different national data sources (Vital Statistics, the National Natality Survey, and the National Survey of Family Growth). Differences among the three sources are discussed; and drawing upon what we know of the problems of data collection, we speculate on the most accurate measure of access to care. Finally, suggestions for improving future data collection are made.
产前护理的时机已成为衡量护理充分性最广泛使用的指标，主要是因为它易于衡量且可从国家数据收集来源获取。由于它是制定政策目标的关键要素，因此准确衡量护理时机非常重要。本文回顾了通过三种不同国家数据来源（生命统计、全国出生调查和全国家庭成长调查）衡量的现有产前护理可及水平。讨论了这三种来源之间的差异；并根据我们对数据收集问题的了解，推测了衡量护理可及性的最准确方法。最后，提出了改进未来数据收集的建议。
