Graph to compare heights and gender9/10/2023 ![]() ![]() ![]() In a clinical situation, height measurements are seldom taken more often than once per office visit, which may mean sampling taking place a week to several months apart. Height measurements are by nature subject to statistical sampling errors even for a single individual. Developing countries such as Guatemala have rates of stunting in children under 5 living as high as 82.2% in Totonicapán, and 49.8% nationwide. This has been seen in North Korea, parts of Africa, certain historical Europe, and other populations. Malnutrition including chronic undernutrition and acute malnutrition is known to have caused stunted growth in various populations. Ĭhanges in diet (nutrition) and a general rise in quality of health care and standard of living are the cited factors in the Asian populations. Moreover, when the production and consumption of milk and beef is taken to consideration, it can be seen why the Germanic people who lived outside of the Roman Empire were taller than those who lived at its heart. Historically, this can be seen in the cases of the United States, Argentina, New Zealand and Australia in the beginning of the 19th century. Therefore, populations with high cattle per capita and high consumption of dairy live longer and are taller. Nations that consume more protein in the form of meat, dairy, eggs, and fish tend to be taller, while those that obtain more protein from cereals tend to be shorter. Average height in a nation is correlated with protein quality. The uneven distribution of nutritional resources makes it more plausible for individuals with better access to resources to grow taller, while individuals with worse access to resources have a lessened chance of growing taller. Īttributed as a significant reason for the trend of increasing height in parts of Europe are the egalitarian populations where proper medical care and adequate nutrition are relatively equally distributed. Average height is relevant to the measurement of the health and wellness ( standard of living and quality of life) of populations. Genetics is a major factor in determining the height of individuals, though it is far less influential regarding differences among populations. For individuals, as indicators of health problems, growth trends are tracked for significant deviations, and growth is also monitored for significant deficiency from genetic expectations. Growth has long been recognized as a measure of the health of individuals, hence part of the reasoning for the use of growth charts. The study of height is known as auxology. In regions of poverty or warfare, environmental factors like chronic malnutrition during childhood or adolescence may result in delayed growth and/or marked reductions in adult stature even without the presence of any of these medical conditions.ĭeterminants of growth and height The median (50th percentile) growth curves for males and females 0–20 years in the United States. The development of human height can serve as an indicator of two key welfare components, namely nutritional quality and health. Exceptional height variation (around 20% deviation from average) within such a population is sometimes due to gigantism or dwarfism, which are medical conditions caused by specific genes or endocrine abnormalities. When populations share genetic backgrounds and environmental factors, average height is frequently characteristic within the group. Short stature decreases the risk of venous insufficiency. The University of Hawaii has found that the "longevity gene" FOXO3 that reduces the effects of aging is more commonly found in individuals of small body size. Individuals of small stature are also more likely to have lower blood pressure and are less likely to acquire cancer. Studies show that there is a correlation between small stature and a longer life expectancy. Height is also important because it is closely correlated with other health components, such as life expectancy. In the early phase of anthropometric research history, questions about height techniques for measuring nutritional status often concerned genetic differences. It is measured using a stadiometer, in centimetres when using the metric system or SI system, or feet and inches when using United States customary units or the imperial system. Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect. ![]() For other uses, see Height (disambiguation). ![]()
