Summary
Pubertal growth
Area of Science:
- Human growth and development
- Pediatric endocrinology
Background:
- Limited data exist on the precise timing of the pubertal growth spurt across diverse populations.
- Understanding the pubertal growth spurt's contribution to final height is crucial for growth assessment.
Purpose of the Study:
- To investigate the contribution of pubertal growth to overall adult height.
- To determine if this contribution varies significantly between populations or sexes.
Main Methods:
- Analysis of data from 11 reports encompassing multiple populations and longitudinal studies.
- Calculation of the percent contribution of pubertal growth to final height, using age 9 for girls and age 11 for boys as the onset of puberty.
Main Results:
- Pubertal growth's contribution to final height showed remarkable consistency across different populations and sexes (p < 0.003).
- Results for the 50th percentile suggest pubertal growth contribution may be a biological invariant.
- No secular trend was observed in the percent contribution of pubertal growth to final height.
Conclusions:
- The pubertal growth spurt's contribution to final height appears to be a stable biological parameter across populations.
- This finding has implications for understanding normal human growth patterns and identifying potential deviations.

01:18Polygenic Traits
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...
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...
00:57Population Growth
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.However, realistic environmental conditions limit the number of...
02:32Variation: Normal Distribution, Range, and Standard Deviation
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...
01:22Applications of Normal Distribution
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.

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...
