Hormonal imbalances can make people unusually tall or short. Nutrition: Nutrition is an important factor in growth. People who have poor nutrition may not grow as tall, especially those who do not get enough calcium , vitamin D , or other key vitamins and minerals.
Geographic location: There is a significant relationship between geographic location and ethnicity, which can contribute to height.
Beyond this factor, location affects exposure to natural sunlight, which is a source of vitamin D. Stunted growth: Factors that stunt growth can cause people to grow less tall than they otherwise would.
These factors may include eating disorders, severe illnesses, and exposure to some medications. How does height vary for females around the world? Find out more. Several health conditions can affect height, such as diabetes , cardiovascular disease, kidney failure, and cancer. A handful of other conditions can also cause extremes in height, such as:. Achondroplasia is a medical condition that causes unusually short arms and legs.
It is also the leading cause of dwarfism. Spondyloepiphyseal dysplasias SED causes a person to develop a shorter-than-average trunk. It is also a genetic condition, but many people do not receive a diagnosis until middle childhood. Dwarfs may experience a variety of health issues. SED, for example, can cause severe osteoarthritis. Children with an adenoma, or a tumor of the pituitary gland, may secrete too much growth hormone.
This causes them to grow much taller than they otherwise would. Gigantism is almost always the result of a pituitary tumor, though some rare medical conditions can also cause excessive growth. These include:. People who are extremely tall are also at risk of several health issues. Their excessive size can strain the metabolic system and cause cardiovascular problems, including an enlarged heart. Other studies have found that low socioeconomic status — and its connection to poor nutrition and infections early in life — may be to blame for the heart disease-height link.
Numerous studies have found that, on average, taller people not only hold jobs of higher status for instance, sales managers are taller than salespeople , they also earn more money. The findings help up even after researchers controlled for things like gender, weight, and age. In another blow to petite people, science shows that taller folks are also perceived as being more attractive.
In addition to factors such as power and self esteem, leg length may be a surprising influence. People with shorter-than-average legs were viewed as being less attractive than people with slightly longer gams, a study in Evolution and Human Behavior found. Sorry, supermodels: The study also found that having excessively long legs decreased attractiveness.
There may be an evolutionary explanation for the effect, note the researchers. Very short or tall people may have conditions called dwarfism or gigantism, respectively. About one in 15, people have dwarfism, defined as an adult height of 4 feet 10 inches or less. Genetic mutations that cause bones to grow short are the main causes, according to Michael J. At the other end of the spectrum is a more rare condition called gigantism, in which people grow very tall, usually due to an excess of growth hormones during childhood often caused by a benign tumor on the pituitary gland.
Behind the shrinkage: the discs in your spine, which lose water and begin to compress over time. Osteoporosis , a bone-weakening disease that affects up to 10 million Americans, can exacerbate the problem. If you buy through links on this page, we may earn a small commission. The study of measurement of the human body, such as weight, standing height, and skinfold thickness, is called anthropometry.
Scientists use these measurements for nutrition assessment and to come up with averages and trends in human growth. Designers can even use anthropometric data to create more ergonomic spaces, furniture, and assistive devices. Next up are the numbers illustrating the average height for men. This number comes from data published in December The data was collected between and as part of a National Health and Nutrition Examination Survey.
The analytic sample included 47, men and women, all at least 20 years of age. Participants reported their ages, races, and whether they were of Hispanic origin. The average height of 5 feet 9 inches takes all groups into account. A study showed that Iranian men have seen the biggest change in height over the last century, gaining about 6.
They explained that both biological factors such as genetic predisposition and socioeconomic factors such as access to quality foods can affect the range in heights. Some discrepancies may be attributed to self-reporting versus controlled measuring or to the ages of individuals who are recorded. Discrepancies may also be the result of:. It may be tricky to measure your height at home without some help. How tall will I be? The second important part is the timing of puberty.
