A healthier child and adult develops a body that is better able to provide optimal prenatal conditions.
Thus, there is a cumulative generation effect such that nutrition and health over generations influences the height of descendants to varying degrees. The age of the mother also has some influence on her child's height. Studies in modern times have observed a gradual increase in height with maternal age, though these early studies suggest that trend is due to various socio-economic situations that select certain demographics as being more likely to have a first birth early in the mother's life.
Nature versus nurture[ edit ] The precise relationship between genetics and environment is complex and uncertain. A genome-wide association GWA study of more thanindividuals has identified hundreds of genetic variants in at least loci associated with adult human height. This gives insights into the biological mechanisms underlying how these genetic variants affect overall height.
As an example, 4 of the 7 loci identified for intracranial volume had previously been discovered for human height. In the early s, when Bogin first visited Guatemalahe observed that Mayan Indian men averaged only Bogin took another series of measurements after the Guatemalan Civil Warduring which up to a million Guatemalans fled to the United States. He discovered that Maya refugees, who ranged from six to twelve years old, were significantly taller than their Guatemalan counterparts.

February Learn how and when to remove this template message The main pathways in the endocrine regulation of growth Growth in stature, determined by its various factors, results from the lengthening of bones via cellular divisions chiefly regulated by somatotropin human growth hormone hGH secreted by the anterior pituitary gland. Somatotropin also stimulates the release of another growth inducing hormone Insulin-like growth factor 1 IGF-1 mainly by the liver.
Both hormones operate on most tissues of the body, have many other functions, and continue to be secreted throughout life; with peak levels coinciding with peak growth velocity, and gradually subsiding with age after adolescence. The bulk of secretion occurs in bursts especially for adolescents with the largest during sleep. The majority of linear growth occurs as growth of cartilage at the epiphysis ends of the long bones which gradually ossify to form hard bone.
The legs compose approximately half of adult human height, and leg length is a somewhat sexually dimorphic trait, with men having proportionately longer legs.
Some of this growth occurs after the growth spurt of the long bones has ceased or slowed.

The majority of growth during growth spurts is of the long bones. Additionally, the variation in height between populations and across time is largely due to changes in leg length. The remainder of height consists of the cranium.
Height is sexually dimorphic and statistically it is more or less normally distributedbut with heavy tails. Short stature and tall stature are usually not a health concern.

If the degree of deviation from normal is significant, hereditary short stature is known as familial short stature and tall stature is known as familial tall stature.
Confirmation that exceptional height is normal for a respective person can be ascertained from comparing stature of family members and analyzing growth trends for abrupt changes, among others. There are, however, various diseases and disorders that cause growth abnormalities. Most notably, extreme height may be pathological, such as gigantism resulting from childhood hyperpituitarism, and dwarfism which has various causes. Rarely, no cause can be found for extreme height; very short persons may be termed as having idiopathic short stature.
An even rarer occurrence, or at least less used term and recognized "problem", is idiopathic tall stature. This treatment involves the injection of pure growth hormone into thick tissue to promote growth.
These evolutionary pressures result in height related health implications. While tallness is an adaptive benefit in colder climates such as found in Europe, shortness helps dissipate body heat in warmer climatic regions. A person's waist-hip measurement compares their waist size with that of their hips.
Research has shown that people who have more body fat around their middle are more likely to develop cardiovascular disease CVD and diabetes. The higher the waist measurement in proportion to the hips, the greater the risk.
For this reason, the waist-hip ratio WHR is a useful tool for calculating whether a person has a healthy weight and size.
Measure your waist-hip ratio 1. Measure around the waist in the narrowest part, usually just above the belly button. Divide this measurement by the measurement around your hip at its widest part.
If a person's waist is 28 inches and their hips are 36 inches, they will divide 28 by This will give them 0. What does it mean?
How WHR affects the risk of cardiovascular disease CVD is different for men and women, because they tend to have different body shapes. In males Below 0. The risk of cardiovascular health problems is low.Conversion from feet to centimeters by Steve McCrea
The risk is moderate.
