"Genetics is not a decisive factor in mental development": finds a doctor from Rosaria



After more than ten years of work together with a team of 300 experts from around the world, the largest global research on child development and development for up to two years under the guidance of Argentine physician José Villar has arrived today on the pages of a prestigious magazine. nature.

The work was performed at the University of Oxford, where Villar – specialist in obstetrics, gynecology and perinatology – has served as a professor of perinatal medicine and researcher for two decades and their conclusions will change the way pediatricians "measure" the growth and integral development of childrenThis will, in turn, result in benefits during the pregnancy phase, facilitate the detection of baby problems in the early stages and favor the implementation of public health policies that emphasize the well-being of a mother and child, Villar is a great obsession with being a young professional.

The project was the largest prospective population-based prospective study on fetal and neonatal growth and development that encompassed nearly 60,000 mothers and babies, and was conducted in two phases. First, since the tracking of intrauterine growth in each of these pregnant women from different parts of the world. Others, occasionally, evaluate more than 1,300 these babies up to two years.

In order to study growth, health, nutrition and neurological development of 14 weeks of pregnancy up to two years, the team used the same conceptual framework as the multicentre reference study of the World Health Organization. Health (WHO) to produce prescribed standards to complement these standards for child growth in WHO and new phenotypic classification of fetal growth restriction and premature birth syndromes.

Novel results, whose data are consistent with WHO findings about the similarity of growth of healthy and infant children worldwide, lies in their discovery of physical and neurological growth and baby behavior. a very similar rate for children irrespective of their ethnic origin or place of residence, provided that the conditions of life are appropriate and with good nutrition. Moreover, to confirm that neither the color of the skin nor the place of birth indicates differences in these issues, but quality of life, "What really distinguishes us from health is social and economic, not genetic," Villar told the newspaper La Capital his native Rosario from England.

Villar, who for years had been maternal and perinatal health coordinator in WHO, added: "Our study clearly shows that the genetic code is not a central factor of mental development or growth, but that access to medical controls, good nutrition, breastfeeding, adequate accommodation, access to education and low environmental risk".

Researchers from Oxford and their associates compared mothers in similar socioeconomic, health and educational settings but from different ethnic groups and found that there were no differences in development in the two years between boys raised in good condition either from African cities and others from London. "We are much more similar than different, in any case, there is much more difference between poor and" rich "in a particular country than among the" rich "from different parts of the world, to express it in a simple language," the expert said.

Influence of discovery

The results of this research are of international reach, in addition to the World Health Organization's growth standard for children up to five years of age. "For the first time in medicine we have the standard mental development parameters in the two-year boys and girls of the same mothers we studied in the first trimester of pregnancy, Complete assessment, using the same criteria and the same healthy population as standards. This unique strategy of comprehensive mother and child control is first obtained for the mother, the fetus, the newborn, the infant, the infant and the children up to two years, "explains Villar.

Pediatricians (especially mothers and fathers) will have a comprehensive international method, including mental development, "based on WHO criteria, not on a mixture of local curves, sometimes of dubious quality and vague in relation to population-based, non-standardized measures and that change if moved from town or country, "explained the expert.

on that way, The paper provides new tools based on evidence to identify a baby with growth problems in the uterus, a common method for quantifying and comparing the incidence of nutritional deficiencies in populations at birth and the first method based on evidence for postnatal growth of non-mammals.

It is estimated that every year 13 million newborns worldwide will be identified as being undernourished using new standards compared to current practice.
