概括
年龄校正对于评估极度和非常早产婴儿的成长至关重要. 使用校正年龄可以确保在36个月内准确测量体重,身高和头周长.
科学领域:
- 新生儿科学 新生儿科学
- 儿科生长与发展 儿科生长与发展
- 生物统计学 生物统计学
背景情况:
- 极度早产 (<28周) 和非常早产 (28至<32周) 婴儿通常会出现生长偏差.
- 准确的生长评估对于监测这个脆弱人群的健康结果至关重要.
- 当前的生长图表可能无法充分解释早产儿独特的发育轨迹.
研究的目的:
- 确定年龄校正对早产婴儿生长评估的影响.
- 在成长参数评估中,评估时间和校正年龄之间的差异.
- 确定年龄校正的必要性,以监测早产婴儿的生长,直到36个月.
主要方法:
- 从早产婴儿多中心生长研究 (2001-2014) 的数据进行了纵向分析.
- 包括1,416名早产婴儿,平均妊娠年龄为27周.
- 对体重,身高和头部周长的z分数进行比较,使用多个时间点 (0,4,8,21,36个月) 的时间和校正年龄.
主要成果:
- 基于时间年龄的z-score始终低于基于年龄的校正z-score,长度z-score在术语中差异高达-5.2.2.
- 在使用时间学年龄时,出现了严重的生长错误分类:高达72.9%的人被误诊为缩,89.8%的人被误诊为产后体重不足.
- 这些差异凸显了未经年龄校正的早产婴儿生长低估的可能性.
结论:
- 年龄校正对于精确评估极度早产和非常早产婴儿的生长是必不可少的.
- 包括体重,身高和头周长在内的生长指标需要经过36个月的年龄校正.
- 如果不实施年龄校正,可能导致对生长状态的误解,并可能影响临床管理.

01:10Nature and Nurture
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
01:52Regression Toward the Mean
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 researchers try to extrapolate results...
01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
