概括
当前持续时间 (CD) 方法用于估计不孕症时,与前性队列方法相比,其假设得到了可比的结果. 这证实了使用应用程序数据研究不同人群中的不孕症模式.
科学领域:
- 生殖健康
- 流行病学
- 生物统计学
背景情况:
- 与传统的前性队列研究相比,当前持续时间 (CD) 方法为评估人口不孕症提供了一种可行的,具有成本效益的方法.
- 然而,使用基于人口的样本对CD方法假设缺乏严格的测试,这限制了其广泛采用.
研究的目的:
- 评估当前持续时间 (CD) 估计人口不孕症的假设是否得到满足.
- 通过使用生育应用数据,将CD方法获得的不孕率估计与黄金标准事件前性队列方法的估计进行比较.
主要方法:
- 使用了来自生育智能手机应用程序的167,451名潜在队列数据 (2015-2022年).
- 从同一数据源生成6个CD样本 (17,196-26,259名参与者) 来进行比较.
- 使用前性和CD方法测试CD方法假设和估计12个月不育率,按年龄,教育程度,贫困程度分层.
主要成果:
- 显然违反了一个CD假设和另一个暗示证据.
- 预期队列方法的12个月不育率为36. 1%,而调整后的CD估计为37. 0%.
- 根据使用者特征的不孕症模式在两种方法中都相似,年龄较大,无孕,受教育程度较低和较贫穷的个体中患病率较高.
结论:
- 尽管存在违反假设的情况,但经过调整后,CD方法提供了与同一样本内的前性队列设计相匹配的不孕症患病率估计和模式.
- 在缺乏现有估计的群体中,CD方法可以促进不孕症研究,前提是假设违反被统计处理.
- 基于应用程序的估计可能不代表美国人口水平的不孕症,原因是潜在的报告不足和样本特征.

Infertility in Males
331
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Infertility in Females
401
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.

Kaplan-Meier Approach
258
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...
