概括
这项研究在一个大型社区人口中建立了特定年龄的抗米勒尔激素 (AMH) 参考范围. 这些新的百分位数有助于准确地评估女性的生育能力和生殖计划.
科学领域:
- 生殖内分泌学和生育研究.
- 生物标志物分析和人口健康研究.
背景情况:
- 抗穆勒尔激素 (AMH) 是卵巢储备的关键指标,对于生育能力评估至关重要.
- 现有的AMH名录通常缺乏来自一般社区人口的代表性,这可能会限制它们的适用性.
- 与年龄相关的AMH下降需要准确的,特定于年龄的参考值,以有效管理生殖健康.
研究的目的:
- 为AMH水平制定全面的,基于人口的,年龄特定的参考值 (百分数和z-score).
- 提供一个强大的工具来解释在社区环境中生育年龄妇女的AMH结果.
- 为了提高AMH测试的临床实用性,用于生育咨询和生殖规划.
主要方法:
- 这是一项涉及来自社区人口的5230名25岁至45岁以下女性的横截面研究.
- 使用Elecsys Cobas AMH测定法测量了血清AMH水平.
- 以特定年龄为特征的百分位数和z-score是使用位置,尺度和形状的一般添加模型 (GAMLSS) 来生成的,数据分为学习和验证组.
主要成果:
- 观察到AMH水平中位数明显的年龄相关下降,从25岁时的3.03 ng/mL到44岁时的0.31 ng/mL.
- 开发的参考图表允许对AMH结果进行年龄匹配的解释.
- 该模型表现出稳健性,在验证组中平均z分数接近零.
结论:
- 这项研究为AMH提供了基本的,基于社区的参考数据,解决了当前文献中的差距.
- 建立的特定年龄百分比提高了生育评估的准确性,并支持个性化生殖护理.
- 这些发现加强了AMH测试的价值,并强调了为公共卫生战略和生育意识制定标准化,人群特定的参考范围的必要性.

01:18Percentile
8.5K
A percentile indicates the relative standing of a data value when data are sorted into numerical order from smallest to largest. It represents the percentages of data values that are less than or equal to the pth percentile. For example, 15% of data values are less than or equal to the 15th percentile.

00:57Population Growth
28.0K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

01:25What is Population Genetics?
64.5K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

01:06Introduction to z Scores
11.0K
A z score (or standardized value) is measured in units of the standard deviation. It tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one.

z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...
