背景：没有及早意识到自己怀孕的妇女可能不会及早开始产前护理。本研究调查了育龄妇女的孕期确认时间、产前检查开始时间和产前检查次数之间的关系。方法：本研究分析了美国孕期风险评估和监测系统(PRMS)的数据。分析样本代表了美国29个州的育龄居民妇女，她们在联系前2至6个月内生下了活着的孩子。结果：在136,373名孕妇中，92.5%(92.5%)的孕妇在怀孕12周时已经意识到自己怀孕了，80%的孕妇在怀孕的前三个月就开始了产前保健。在控制了社会人口学和以前的出生结局数据后，早期怀孕识别与早期开始产前护理的几率显著增加相关(OR=6.05，p<；0.01)，也与产前检查次数少于推荐次数的几率较低以及产前检查次数超过推荐次数的几率较高(OR：11次=0.71，15次=1.17，p<；0.01)。结论：早期怀孕识别与改善产前检查的时间和次数有关。通过鼓励和增强妇女在胎儿发育的关键时刻获得产前护理的能力，促进确认早孕可以成为改善生育结果的一种手段。(出生37：2010年3月1日)。
Background:A woman who does not recognize her pregnancy early may not initiate prenatal care early. This study examined the relationship between the time of pregnancy recognition and the time of initiation of prenatal care, and the number of prenatal visits among women of childbearing age.Methods:This study analyzed the Pregnancy Risk Assessment and Monitoring System (PRAMS) data for the United States. The analysis sample was representative of resident women of childbearing age in 29 U.S. states who had live births within 2 to 6 months before being contacted. The data were weighed to reflect the complex survey design of the PRAMS, and binary and multinomial logistic regressions were used for the analyses.Results:Most (92.5%) of the 136,373 women in the study had recognized their pregnancy by 12 weeks of gestation, and 80 percent initiated prenatal care within the first trimester. Early pregnancy recognition was associated with significantly increased odds of initiating prenatal care early (OR = 6.05, p < 0.01), after controlling for sociodemographic and prior birth outcome data, and was also associated with lower odds of having fewer than the recommended number of prenatal visits and higher odds of having more than the recommended prenatal visits (OR: < 11 visits = 0.71 and > 15 visits = 1.17, p < 0.01).Conclusions:Early pregnancy recognition was associated with improved timing and number of prenatal care visits. Promotion of early pregnancy recognition could be a means of improving birth outcomes by encouraging and empowering women to access prenatal care at a critical point in fetal development.
