Human Height And Demographic Research

Powerful Essays
Human height is the distance from the bottom of the feet to the top of the head in a human body, standing erect.
When populations share genetic background and environmental factors, average height is frequently characteristic within the group. 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.[1]
In regions of poverty or warfare, environmental factors like chronic malnutrition during childhood or adolescence may account for delayed growth and/or marked reductions in adult stature even without the presence of any of these medical conditions.

Growth has long been recognized as a measure of the health of individuals, hence part of the reasoning for the use of growth charts. 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. Genetics is a major factor in determining the height of individuals, though it is far less influential in regard to populations. Average height is relevant to the measurement of the health and wellness (standard of living and quality of life) of populations.[2] Attributed 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.[3] Changes in diet (nutrition) and a general rise in quality of health care and standard of living are the cited factors in the Asian populations. Average height in the United States has remained essentially stagnant since the 1950s even as the racial and ethnic background of residents has shifted. Malnutrition including chronic undernutrition and acute malnutrition is known to have caused stunted growth in various populations.[4] This has been seen in North Korean, portions of African, certain historical European, and other populations.[5] Developing countries such as Guatemala have rates of stunting in children under 5 living as high as 82.2% in Totonicapán, …show more content…
Meanwhile, in many sports taller people have a major advantage. They include certain professional sports (see section "Sports"), fashion modelling, etc. In most occupational fields, body height is not relevant to how well people are able to perform. A correlation has been found between body height and occupational success in several studies, although there may be other factors such as gender or socioeonomic status that may have been influencing the subjects ' heights as well as their occupational

    Puberty is universal across the world, however social milestones such as beginning school varies between cultures. Physical appearances, such as race and racial stereotypes can have great impacts on a child’s development. In a society that is much racialized children become aware of the dynamics of racism at a very young age. In some cultures children are doing more physical duties in their community which affects their physical development. Another example of a particular region affecting a child’s physical development is a child that is growing up in a poorer country that does not have enough food to eat to reach optimal development, resulting in many children becoming malnourished at a young…

    Some children have a poor diet and this can affect their growth and thus affect the physical side of development. There have been many studies on diet and its effects and results have shown that a child who has a nutritious and healthy diet achieves more in life. It is difficult for a family on a low income to promote a healthy diet for their child and thus can result in poorer health and physical issues. Also some children’s genetic code may affect the pattern in which they develop. This could mean that they are slower to develop but no reason is found.…

    Physical development is physical growth of the body. During childhood, physical growth includes gross motor, which are the big muscles, and fine motor, which help gain control of the body. Physical growth patterns start with gross motor development and then fine motor development occurs. At approximately one year old, a baby can walk by itself. By the age of three, a child has shown sufficient growth by sitting, walking, toilet training, using a spoon, scribbling, and sufficient hand-eye coordination to catch and throw a ball. Around age five a child’s fine motor skills are obvious and the child can perform actions like scribbling. From age five to approximately age 12, huge developments are not apparent and the child’s skills are simply refined. While many physical developments, like growing taller, are concrete; the amount of vertical growth heavily depends on a child’s diet. Socioeconomic status is a big contributor to physical development because if the child’s parents do not have the money to provide essential food to the child, the child will not grow as tall as they could be (Eitzen, Zinn & Smith, 2011).…

    As practitioners working with children, there is a great deal that must be known, it is important that there is an understanding of the different aspects of development and also a greater understanding between the sequence of development and rate of development and why the difference of the two is important. The physical growth and development growth of children underpins other aspects of their development, the two go hand in hand and it can often be difficult to separate one from another.…

    As a child grows the changes in weight and height size are measured on a centile chart, these charts show the expected pattern at the particular ages. Development refers to the skills and abilities that you learn through life, but as we all know children are all individual and so when centile charts are used they are based on the “average” child but all children meet these different goals in their own time and don’t always fit nicely into the correct average box.…

    what genes a child possesses from their parents can determine how a child grows and develops, for example, each person is supposed to have 46 (23 paired from the mother and father) however some may have 47 chromosomes as a biological error and this causes the baby to have down syndrome, because of this the child will have ‘learning difficulties, a characteristic facial appearance and poor muscle tone (hypotonia) in infancy.’ (https://www.genome.gov/11508982/chromosome-abnormalities-fact-sheet/) this means that the child will not grow and develop the same as other children, because of their weak muscles, the baby will not be able to reach physical milestones according to the normal rate of development, their physical development will be slowed right down because of this. Other genetics may slow down the rate of physical development, for example, asthma, a child may not be able to do physical activities for as long as their children because of this. Other children with different genetics may strive with their physical development because of the genetics they possess, it may be just because they are good at it however it may be opposite with other babies and young children. All children have a different rate of development and will reach physical milestones at different ages and this may be down to genetics. Brain based investigation expresses the importance of physical movement and activities within young children and states that ‘sitting young children down to learn in a formal way is not the most effective form of supporting learning’ (children and young people’s workforce, Maureen…

    CDC Growth Charts

    In practice, clinicians use growth charts as standards rather than references. The CDC growth charts consist of a set of charts for infants birth to 36 months of age and a set of charts for children and adolescents from age 2 to 20 years. The charts for infants include sex-specific percentile curves for weight for age, recumbent length for age, head circumference for age, and weight for recumbent length. The CDC recommends that the WHO growth charts be used for children younger than 2 years of age, and the CDC charts for all children older than the age of 2. The WHO charts are based on information from a study engineered specifically for development of growth charts. These charts are standards that reflect how an infant should grow given optimal conditions. They also use breastfeeding as the standard method of feeding for optimal growth.2…

    Infants typically double their birth weight by the fourth month and triple it by their first birthday. Physical growth slows in the second year, but it is still rapid. By 24 months most children weigh almost 30 pounds (131⁄2 kilograms) and are between 32 and 36 inches (81–91 centimeters) tall. This means that typical 2-year-olds are already half their adult height. They are also about 15 to 20 percent of their adult weight, four times as heavy as at birth. Each of the above numbers is a norm, an average or standard for a particular population. Norms must be carefully interpreted. The “particular population” for the norms above is a representative sample of North American infants, who may be unlike representative samples of infants from other regions of the world. To understand norms, you also need to understand percentiles. A child who is average is at the 50th percentile, a number that is midway between 0 and 100, with half of the children above it and half below it. Percentiles allow a child’s growth to be compared not only with that of other children but also with his or her own prior development.…
