目的：为了确定不孕症的下降是否在各亚组之间是一致的。设计：来自全国生育率调查和全国家庭增长调查的定期数据被用来确定哪些因素导致了12个月内不孕症的下降。设置：全国家庭增长调查，一项定期的美国全国代表性研究。患者：一个全国性的15-44岁已婚妇女的代表性样本，N = 15，303，用于4个调查年的汇总数据。干预措施：无。主要结果测量：估计15-44岁已婚妇女的不孕症患病率。结果：在美国，12个月不育率从1982年的8.5%下降到2002年的7.4%，这是非常显著的。这种下降在几乎所有已婚妇女分组中都很明显。在多变量分析中，12个月的不孕症更可能发生在年龄较大、未经生育、非西班牙裔黑人或西班牙裔、没有大学学位的妇女中。12个月的不孕症的下降，即使在控制了人口的组成差异随时间的推移，观察到的结论（S）：在美国的mairred妇女，有一个显着的下降12个月的不孕症，这不能解释的人口组成的变化，从1982年至2002年。
Objective: To determine if the decline in infertility has been uniform across subgroups.Design: Periodic data from the National Fertility Survey and the National Survey of Family Growth were used to determine which factorrs contributed to the decline in 12-month,infertility in the Uhited States.Setting: National Survey of Family Growth, a periodic US nationally representative study.Patient(s): A nationally resentative sample of married women aged 15-44 years, N = 15,303 for pooled data across 4 survey years.Intervention(s): None.Main Outcome Measure(s): Estimates of infertility prevalence among married women aged 15-44 years.Result(s): The decline in 12-month infertility in the United States from 8.5% in 1982 and 7.4% in 2002 was significant. This decline was evident in nearly all subgroups of married women. In the multivariate analysis, 12-month infertility was more likely among women who were older and nulliparous, were non-Hispanic black or Hispanic, and did not have a college degree. The decline in 12-month infertility was observed even after controlling for the compositional differences of the population over time.Conclusion(s): Among mairred women in the United States, there has been a significant decline 12-month infertility, which cannot be explained by changes in the composition of the population from 1982-2002.
