摘　　要：目的分析应用传统与改良的预产期推算公式推算预产期的差异。方法收集2014年1月-2015年2月在重庆市妇幼保健院单胎足月经阴道自然分娩的37–41+6周的产妇2055例(初产妇1300例,经产妇755例),其中39–41周的产妇1224例(初产妇832例,经产妇392例)。分别应用传统与改良的预产期推算公式推算预产期,比较两种方法推算的预产期与实际分娩日期的符合率。结果传统方法推算的预产期与实际分娩日期的符合率(39-41周),初产妇为8.4%,经产妇为9.7%;改良方法推算的预产期与实际分娩日期的符合率,初产妇为11.9%,经产妇为14.8%。改良公式推算的预产期符合率均明显高于传统公式推算的预产期符合率(P<0.05)。结论改良公式比传统公式推算的预产期更准确。Objective To analyze the difference of the delivery date reckoned by traditional and modified formula for calculating the expected date of confinement（EDC）. Methods The data of 2055 women（37-41^＋6 week） were collected who gave monotocousa term spontaneous birth in the Chongqing Health Center for Women and Children from Jan. 2014 to Feb. 2015. Of which 1300 were primipara, and 755 were multipara; and the data of 1224 women（39-41week） were collected, of which 832 were primipara, and 392 were multipara. The expected date was calculated with traditional and modified calculating formula, and then the actual delivery date was used for comparison and statistical analysis. Results The coincidence of actual delivery date with the estimated due date reckoned by traditional formula（39-41week） was 8.4% in primipara and 9.7% in multipara, and the coincidence reckoned by modified formula was 11.9% in primipara and 14.8% in multipara. The EDC estimated by modified formula was more precise than that calculated by traditional formula（P〈0.05）. Conclusion The EDC calculated with modified formula is more accurate than that calculated with traditional formula.
