There are several factors that predispose to having a premature birth, including genetics. More precisely the maternal one, as two new studies have revealedon the genes inherited from the mother who predispose to have a baby before the 37th week of gestation.
Studies suggest that it is only the maternal genes and not those inherited from both parents that affect fetal development in a way that increases the risk of being born prematurely.
To determine this, the scientists analyzed the births of millions of babies in Denmark and Sweden, and in both cases the results were similar.
In women whose mother, sister or half-sister (of the same mother) had had a premature birth, they found that they were 60 percent more likely to have a baby prematurely.
AdvertisingOn the other hand, premature deliveries of women members of the paternal side of the family or between the wives of male relatives did not influence the risk of giving birth in advance.
It does not mean that the risk is high in women with a mother or sister who has had a preterm birth, but there are certain genes that influence fetal development whose imprint is manifested depending on who is inherited, the mother or the father.
