The International Researchers’ team analyzed data on heights and weights of more than 135,600 men and women who have not obese from all over the world and connected this information to the national level of prosperity. While both men and women become higher and harder as countries become richer, researchers have found that the trend of men is twice as high in women. At 22 January study published in Letters of biologyThe team suggests that this is at least partially due to modern sexual preferences.
“Our inter-ethnic analyzes suggest that, as the social and environmental conditions of nations are improved, including the reduction of the overall load of the disease, the height and severity of people increases, but more than twice as much in men, resulting in a larger SSD [sexual size dimorphism]”Researchers from Italy, the US -Ai UK wrote in a study. Sexual dimorphisms are physical differences between sexes of the same species.
Researchers speculate that it is more likely that women will choose more and muscular men as partners, while men, on the other hand, can care less about the height of women.
The dramatic difference in increased height between sexes in the more prosperous countries also suggests that the morphology of men may be more sensitive to the environment than in women.
“Based on our main finding that the SSD is greater in more favorable environments, it is clear that the development and maintenance of gross morphology is more sensitive to men’s living conditions than in women, at least in terms of height and weight,” researchers wrote in the study.
In other words, “how () an ecological or economic situation improves and there is better access to resources, males receive more biological benefits from women. The opposite is true when resources are scarce (males ‘suffer’ more than females), “said biologist Bogusław Pawłowski of Wrocław University in Poland, which was not involved in the studio, he said CNN.
Although researchers acknowledge that their results can only show the connection between data (as opposed to any final causes and consequences), they ultimately suggest that the height of men, as well as gender -based differences, could be useful to monitor the monitoring of supervision Changes in population health.
