"Genetics is not a decisive factor in mental development": a physician from Rosario



After more than a decade of collaboration with a team of 300 specialists from around the world, the world's largest research for child development and growth up to two years, led by Argentine doctor José Villar, arrived today at the prestigious magazine Nature,

The work took place at Oxford University, where Villar, a obstetrician, gynecology and perinatology specialist, worked for two years as a professor of perinatal medicine and research and their conclusions will change the way pediatricians "measure" growth and the integral development of childrenThis will result in benefits during the pregnancy stage, will allow recognition of the child's problems in the early stages and will support the implementation of public health policies that emphasize the wellbeing of motherhood and child. He was a young professional.

The project was the largest prospective, population-based study on the development and development of the fetus and neonate that took place, involving nearly 60,000 mothers and children, and took place in two phases. The first of monitoring intrauterine growth in each of these pregnant women from different parts of the world. Second, regularly evaluating more than 1,300 of these children up to two years of age.

For the purpose of studying growth, health, nutrition and neurological development from 14 weeks of pregnancy to 2 years, the team used the same conceptual framework as the World Health Organization's multicentre reference study. Health (WHO) to develop normative norms to complement these WHO standards for child upbringing and a new phenotypic classification of fetal growth limitation and premature birth syndromes.

The new results, which are consistent with World Health Organization (WHO) findings on growth similarities in healthy and breast-fed infants across the globe, reveal that physical and neurological growth and behavior of children are very similar in children regardless of age to their ethnicity or place of residence, provided that living conditions are adequate and have good nutrition. And what more, confirm that neither the color of the skin nor the place of birth observe differences in these issues but the quality of life, "What really makes us healthier is more socio-economic than genetic," said Villar in the La Capital magazine of his native Rosario, England.

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

Oxford researchers and their coworkers compared their mothers in similar socio-economic, health and educational situations but from different ethnic groups, and found that between two years there were no differences in development among boys who were in good condition from the African city and the other from London. "We are much more similar than others, in many cases there are many more differences between the poor and the" rich "in a particular country than among the" rich "from different parts of the world, to be simply said," the expert stressed.

The impact of the discovery

The results of this research have an international scope, in addition to WHO standards for children under five. "For the first time in medicine, we have standard parameters of mental development in two years of boys and girls of the same mothers we studied in the first trimester of pregnancy, Complete rating using the same criteria and the same healthy population as standards. This unified strategy of comprehensive parental control is first acquired for mother, fetus, newborn, premature infants, infants and children up to two years of age, "explains Villar.

Pediatricians (and especially mothers and fathers) will have a comprehensive international method, including mental development, "based on WHO criteria, and not on a combination of local curves, sometimes dubious quality and unclear relationship to what population they are based on, with measures that are not standardized and which change if they move from city or country, "explained the expert.

So, The work provides new evidence-based tools for identifying children with growth problems in the uterus, a common method for quantifying and comparing the occurrence of nutritional deficiencies in births and the first method based on evidence to monitor the postnatal growth of preterm infants.

It is estimated that more than 13 million newborns worldwide will be identified as malnourished every year around the world with new standards compared to current practice.
