How Human Height Increases

Many people have wondered how human height increases and what factors are responsible. There are several possible factors: Growth hormones, growth plates, and education. However, no single factor is responsible for every individual’s growth. Here’s what we do know. During the past century, the average height of British and European citizens increased by 3.9in (10cm) or 7.8in, respectively. Despite the dramatic increases in height, the causes of these increases remain unknown. Some people are naturally tall and may wonder how to get shorter.

Growth hormones

The human growth hormone is secreted by the pituitary gland in the brain and has been found to be responsible for increasing the height of children with abnormally short stature. In one study, Swedish researchers followed 151 children for 20 years. Their average height gain was 3 inches. Despite the positive results, there are no studies comparing the effects of growth hormone treatment with that of children who had normal levels of growth hormones.

In addition to the growth hormone, the pituitary gland also makes many other hormones that affect growth, including testosterone. Growth hormones influence a person’s height by regulating growth, and a lack of it can lead to a low adult height. In children, excessive growth hormones may cause a condition called gigantism, a condition in which their hands, feet, and face grow larger than normal. Treatment for this condition includes surgery to remove the tumor or medicines. In severe cases, the doctor may prescribe radiation therapy.

Growth plates

If you’re wondering how human height increases, you’re not alone. Genetics is one of the biggest factors determining human height. In most cases, growth plates close when we hit puberty, but sometimes they stay open until later in adulthood. Even so, it’s still unclear exactly how the plates close. Luckily, there are many ways to encourage growth during adolescence, including eating a healthy diet, getting enough sleep, and engaging in various physical activities. However, these habits can also negatively impact the growth process.

The linear growth rate (LGR) is a useful marker of growth plate senescence. The rate of linear growth drops dramatically with age. While a human fetus grows 100 cm per year, this rate drops to 50 cm per year by birth and only five cm per year during childhood. This decline is interrupted by the pubertal growth spurt, which interrupts this pattern. Animal studies have also suggested that the slowdown of linear growth in humans is due to intrinsic changes in the growth plate.

Environmental factors

Increasing evidence suggests that humans’ height is largely determined by a combination of genetic and environmental factors. This study assessed the extent to which genetic and environmental factors contribute to the variability of height across birth-year cohorts. A pooled study of height variation found that genetic and environmental factors accounted for the majority of variance. In addition, genetic and environmental factors were found to contribute to the greatest proportion of variation in height in the United States, Europe, and East Asia.

The authors used the classic twin modeling approach by Neale and Cardon. These twins are identical-by-descent and share 50% of their genomes. The variance in height can be further broken down into additive genetic and dominance genetic effects, as well as unique environmental factors. In addition, common environmental effects were defined as those that were correlated with height in MZ and DZ twins while unique environmental effects were defined as those that were uncorrelated across the two pairs.


The association between educational attainment and human height has long been a topic of debate. In cross-sectional studies, the relationship between height and education is correlated with parent socioeconomic status. In a longitudinal study, however, there has been little agreement as to the relative importance of these factors. Here, a nation-wide record-linkage cohort study of 950 000 Swedish men followed their attained educational status for 27 years after their baseline. The association between educational attainment and human height was examined using logistic regression models adjusted for age and cognitive ability, parental socioeconomic status, and shared family background.

The modern Europeans have significantly higher average heights than most other human populations. In contrast, the average height of Africans is decreasing. In the past, human heights varied significantly among different countries. In contrast, living standards in Sub-Saharan Africa have improved, while average human height has fallen. It is unclear which factor is most responsible for these diverging trends. While the correlation between human height and education is not absolute, it does suggest that there may be an underlying biological or genetic mechanism that can explain the observed disparity.

Income inequality

An increasing body of literature has investigated the relationship between anthropometric inequality and economic inequality. One indicator of anthropometric inequality is standard deviation, also known as Pearson’s Coefficient of Variation or Relative Standard Deviation. The standard deviation is an intuitive indicator of inequality. In fact, some biomedical research suggests that standard deviation increases as human height increases. Therefore, it is possible that anthropometric inequality increases with age.

While it is possible that the relationship between height and income inequality is causal, it is unclear whether this relationship is merely an association. The relationship is complex, despite the observable correlation between the two measures. One explanation for the correlation is that the social distribution of height and income are linked to changes in inequality. For instance, a change in relative food prices might result in a decline in income inequality. On the other hand, changes in the relative cost of food might explain the opposite trend.
