概括
根据母亲的身高定制出生体重图表可以改善对妊娠年龄小 (SGA) 和妊娠年龄大 (LGA) 婴儿的分类. 这张新的图表确保了在不同母亲身高范围内更一致的SGA和LGA流行率.
科学领域:
- 围产儿医学 围产儿医学
- 儿科内分泌学 儿科内分泌学
- 公共卫生 公共卫生
背景情况:
- 出生体重图表对于评估胎儿生长和识别偏差至关重要,例如对于妊娠年龄来说小 (SGA) 和对于妊娠年龄来说大 (LGA).
- 当前的图表可能无法充分解释母体人体测量的变化,这可能导致错误分类.
- 母亲的身高是影响胎儿生长和出生体重的重要因素.
研究的目的:
- 开发和验证一个根据母亲身高定制的出生体重表.
- 评估母体身高定制对SGA和LGA婴儿分类的影响.
- 将定制图表的性能与现有的标准图表进行比较.
主要方法:
- 利用了来自荷兰 (2012-2020) 的MiCaS项目 (n=21,350) 的数据.
- 使用哈德洛克的方法构建了MiCaS出生体重图表,结合了七个母亲身高类别 (5厘米间隔).
- 计算了SGA (
p90) 患病率,使用新的定制图表和当前荷兰图表进行比较.
主要成果:
- 定制的MiCaS图表显示,随着母亲身高的增加,相同百分点的出生体重值更高.
- 荷兰标准图表显示,随着母亲身高的增加,SGA患病率下降,LGA患病率增加.
- 定制的MiCaS图表显示,在母体身高类别中,SGA和LGA患病率更为稳定,范围更窄 (SGA3.3%,LGA1.7%).
结论:
- 根据母亲身高定制的MiCaS出生体重图表提供了SGA和LGA分类在不同母亲身高之间更公平的分布.
- 定制显著减少了在标准图表中观察到的偏差,在这些图表中,母亲的身高会影响SGA/LGA的分类.
- 这种方法提高了识别新生儿生长偏差的准确性和可靠性.

Regression Toward the Mean
6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

z Scores and Area Under the Curve
10.4K
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...

Polygenic Traits
65.5K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Applications of Normal Distribution
5.0K
The normal distribution is a useful statistical tool. One of its practical applications is determining the door height after considering the normal distribution of heights of persons, such that many can pass through it easily without striking their heads. The normal distribution can also determine the probability of a person having a height less than a specific height.
The heights of 15 to 18-year-old males from Chile from 1984 to 1985 followed a normal distribution. The mean height is 172.36...

Normal Distribution
10.6K
The normal, a continuous distribution, is the most important of all the distributions. Its graph is a bell-shaped symmetrical curve, which is observed in almost all disciplines. Some of these include psychology, business, economics, the sciences, nursing, and, of course, mathematics. Some instructors may use the normal distribution to help determine students’ grades. Most IQ scores are normally distributed. Often real-estate prices fit a normal distribution. The normal distribution is...

Variation: Normal Distribution, Range, and Standard Deviation
22.2K
In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...
